Chapter 630: Crossroads (Please Vote for the Big Chapter)

"I think the deeper we go on this spaceship, the weirder things we encounter," Ye Yun sat in front of the instrument panel, "We have no way to guarantee that we won't get separated. It's better to have something to verify each other's identity, such as a token, such as a secret code, so that if I meet you again after getting separated, I can quickly rebuild trust." Strictly speaking, there is nothing wrong with Ye Yun's suggestion. After all, in a weird and extraordinary scene, it's not surprising that anything happens. When He Ao first entered the ruins, he met a B-level monster pretending to be Liu Nan. Of course, although He Ao has verified Ye Yun's life card and confirmed Ye Yun's human identity through his divine sense, in fact, the mutual trust between the two of them so far is actually based on such a long period of fighting side by side. After all, before this, He Ao had almost no contact with Ye Yun, even if the two were both from the research institute, there was no basis for trust. From Ye Yun's perspective, his "trust" in He Ao should be similar. After all, at the beginning, when the two met, he also expressed his vigilance against He Ao. From another perspective, the fact that he asked this question at this moment also meant that his "trust" in He Ao had reached the level of "comrades-in-arms" who could rely on each other. At least, he was no longer on guard against He Ao.

So, in a sense, asking this question was a way to express goodwill and a way to bring the two sides closer to trust each other.

Common secrets are often the bond that maintains trust.

After Ye Yun finished speaking, He Ao casually cut off the monster behind the car and quickly dug out the monster's energy source, and did not answer the question immediately.

"Well, if you don't think it's necessary,"

Ye Yun hesitated for a moment and spread his hands, "We can also not do it, after all, we may not encounter things that require us to separate."

The entire carriage fell into a brief silence, leaving only the roar of the monster.

"What do you want to use as a 'code'?"

With the next wave of blood splashing, He Ao's calm voice sounded.

"Anything is fine."

Ye Yun smiled, stood up, and walked to He Ao's side, "How about the standard code of the institute?"

The so-called standard code is actually a set of basic code codes set by the institute.

This codeword is composed of a group of chaotic symbols. When writing, these symbols are arranged in an almost chaotic order.

However, the meanings of these symbols are not fixed.

The same symbol may even correspond to hundreds of different characters in different writing situations.

The key to deciphering this codeword is the "headword", which is a group of symbols with special meanings.

The encryptor mixes these symbol groups into the codeword. The solver knows these symbol groups in advance, and then deciphers the codeword in the order indicated by the symbol groups, and can understand the original meaning of the codeword.

For the same group of codewords, if the headword symbol groups are different, the deciphered meaning may be very different.

So this set of standard codewords of the institute is completely open, but as long as the decipherer does not know the headword symbol group of the encryptor, he cannot decipher the meaning of the codeword.

And this set of standard codewords can also be converted into a simple code form, which is actually not complicated to learn, so it is widely used in the institute.

In the institute, most of the senior researchers have mastered this set of standard codewords.

Well, the problem is that He Ao is not a senior researcher.

He had only joined the institute for a month, and he had never learned this codeword, but only had a general understanding of it.

But it was not important.

The moment he heard Ye Yun mention the ‘standard codeword’, he controlled Hao Yi’s clone who was still in the main world, turned on the computer on the spot, and visited the institute’s website.

This codeword is completely public, so even if it is Hao Yi’s authority, it can be directly accessed.

He Ao controlled Hao Yi’s clone, and his eyes quickly swept over the content of the codeword.

At the same time, he looked at Ye Yun, “What prefix do you want to set?”

Ye Yun looked up at the camera behind him, raised his hand in front of He Ao with his back to the camera, and wrote two groups of symbols on his hand.

The corresponding meanings of these two groups of symbols are ‘leaves’ and ‘rivers’ respectively.

The prefix is ​​not limited to only one group of symbols. In fact, the more complex the codeword, the more symbol groups are used.

“What is the code you want to agree on?”

He Ao asked.

"The mountains and rivers of my hometown are beautiful."

Ye Yun, with the camera on his back, whispered to He Ao, "I will write this sentence in standard code when the time comes."

"Okay."

He Ao nodded.

"What about you?" Ye Yun looked at He Ao, "What code do you want to agree on?"

"I don't use standard code,"

He Ao raised his hand, avoiding the camera's sight, and quickly wrote a symbol on the palm of his hand.

"Is this your signature?"

Ye Yun looked at He Ao's moving fingers in surprise, "It's so beautiful, did you ask someone to design it?"

"I designed it myself,"

He Ao glanced at him, "So far, only we know this signature."

"Okay."

Ye Yun nodded, he smiled, "Compared to you, my code seems to be a bit complicated."

The password does not necessarily need to be complicated. A simple design such as a signature is also acceptable. The key point is that it cannot be copied and known by a third party.

"As long as the effect is the same."

He Ao nodded slightly and began to concentrate on dealing with the monsters outside.

After exchanging passwords, the two took turns killing monsters several times, and the number of monsters following the car gradually decreased.

"These guys are so annoying,"

Ye Yun, who finally got some rest, leaned against the wall and took a breath. Then he looked at A02, "That artificial retard, when can we get there?"

"The next stop is the station closest to the core control room. After arriving at the station, you still need to walk for a while to reach the door of the core control room."

A02 answered slowly.

"Looks like we're finally going to catch up with that bastard Yin Weier."

Ye Yun smiled, and then he looked behind the car door again.

At this moment, there are almost no monsters chasing behind the car door.

He looked at this scene with some emotion, "I didn't expect that the closer we got to the core, the fewer the monsters would be."

"That's not necessarily good news."

He Ao put away the bone sword, walked to the instrument panel, and held the network card that he had pulled out when he just tested the terminal.

"What's the meaning?"

Ye Yun had some doubts.

boom--

The moment his words fell, the dark tunnel was suddenly torn apart.

A faint light shines through the huge hole in the dim tunnel.

"run!"

He Ao pulled out the network card and jumped out of the door without hesitation.

This time Ye Yun didn't hesitate. He followed He Ao's movements and quickly jumped out.

boom--

next moment.

The powerful plasma beam illuminated the entire dark space like daylight.

This blazing beam instantly penetrated the running tram.

The roaring explosion shook the eardrums of He Ao and Ye Yun.

"What is this?"

Ye Yun looked at the gap and asked tremblingly.

At this moment, a mechanical head half covered with squirming flesh poked out of the torn opening of the tunnel.

Countless chaotic mechanical sounds sounded from the mechanical head. Most of the sounds were incomprehensible to He Ao, but there was still a sentence in the second area's language mixed in, which meant,

"Intruder, kill!"

The next second, a huge plasma cannon stretched out from the monster's eyes and aimed at He Ao and Ye Yun.

The two of them rolled forward and jumped again.

Fiery light struck the tunnel wall behind them, punching a large hole in the wall.

He Ao stared at the head of this mechanical monster.

This mechanical monster's head alone is several meters in diameter.

The feedback from his spiritual consciousness told He Ao that judging from the density of energy flow, this monster was infinitely close to Class B.

The plasma cannon alone was much larger than the plasma cannon of the tentacle monster we met before.

To get rid of this monster, He Ao must activate super memory, engage in a fierce battle, and even use the power of the Miracle Wand to cause landslides and tsunamis.

That would exhaust most of his cards.

This is not conducive to He Ao stopping Yin Weier, because he still doesn't know if Yin Weier has any other trump cards.

"Let's go there."

He Ao did not hesitate and jumped directly into the large hole that had just been penetrated by the plasma cannon.

Judging from the previous battles, these monsters in the Navigator all have their own 'territory'.

Normally, they don't stray too far from their territory.

In other words, this monster can be avoided.

"Why didn't this guy attack Yin Weier in front of us?"

Ye Yun also followed He Ao, running in embarrassment and shouting loudly.

"Run forward and see if you can avoid it."

He Ao responded loudly. At this moment, the two of them were in a dark corridor.

A flash of light penetrated the ceiling above the two men, and a violent explosion sounded behind them.

"Intruder, kill!"

The noise of machinery echoed in their ears.

If you really can't hide, you have to fight hard.

Even with Ye Yun's help, He Ao was not sure that he could completely kill this monster without using all his strength.

And once he exhausts all his strength here, it means that he will completely lose the chance to stop Yin Weier.

Even if he didn't use up all his strength here and was just held back by this monster, Yin Weir, who was already in front of them, would be able to accomplish his goal without any hindrance.

"Is this guy... brought by Yin Weir... to stop us?"

Ye Yun followed He Ao, breathing heavily.

Such high-speed and violent exercise is a bit too much for him.

A blinding light flashed above them again, and this time the plasma cannon bombardment fell in front of them.

The originally dark corridor has been blasted with more and more openings.

He Ao raised his head and glanced at the top of his head.

Above these openings, there seems to be a huge space.

Where they are now is the corridor under this huge space.

Through the light exposed through the opening, He Ao could vaguely see the footsteps of the giant robot walking above.

Most of the robot's body was covered in squirming flesh. Where its two eyes were, one was a plasma cannon, and the other was a flesh-and-blood hole that glowed with blood-red light.

At this moment, the robot seemed to have discovered that He Ao was watching it. It lowered its head, and a strong light gathered at the muzzle.

He Ao rolled forward suddenly.

A fiery explosion sounded behind him.

That was the sound of the plasma cannon hitting the steel ground.

Doesn't this guy lack energy?

While running, He Ao quickly put the network card he pulled out of his hand into the microcomputer.

At this time, a T-shaped fork appeared in front of him, with two directions on the left and right.

"Go right."

He roughly built a model in his mind, shouted, and ran into the passage on the right.

The right side should be the direction to continue forward.

At the same time, his hands were constantly connecting various lines.

In the process, he dodged several plasma cannons, and the huge robot was getting closer and closer to them.

"Hello, sir, the main artificial intelligence A02 of the Navigator is at your service."

Finally, when the plasma cannon was almost close to He Ao, He Ao connected all the lines.

The image of A02's silver-haired girl appeared on the screen.

"A02, do you have a way to control the big guy outside?" He Ao asked quickly. "According to speculation, sir, you are now under the large mechanical laboratory of the Navigator. I can't connect to the laboratory's network. I am analyzing the noise of the large machinery around you. Please wait..." A02 paused for a moment, "According to calculations, the large machinery is completely out of control at this moment. There is an 80% chance that you will be judged as a spaceship invader and attacked." "Is there any way to avoid this guy?" He Ao asked quickly. "We are analyzing your location." A02 supported his head with his hand and made a thinking gesture. A huge palm suddenly pierced through the ceiling behind the two people and quickly grabbed them. "Ah!" Ye Yun, who was following He Ao, ran hard and even caught up with He Ao's speed in an instant. The two rushed forward frantically and dodged this attack. The monster above their heads grabbed nothing with one blow, and stretched out another hand again, grabbing them in front of them. "Turn left on the road ahead,"

A02 in the screen suddenly raised his head.

There was a fork in the road ahead.

After a brief thought, He Ao chose to follow A02's instructions and turn left.

Ye Yun followed closely behind him.

The giant robot's palm fell in front of the right road and grabbed nothing.

"Turn right on the road ahead,"

"Turn left again,"

"Go straight and turn right at the fork."

A02's instructions kept ringing in their ears.

After dodging again and again, the huge mechanical monster gradually slowed down and the distance between them widened.

"There are two gates at the end ahead. After opening, there will be a 5-second pass time,"

In a dark straight road, A02 slowly spoke, "After passing through the two gates, you will leave the large test area. In this case, sir, you have a 79% chance of getting rid of the pursuit of the large experimental machine."

As her voice fell, He Ao also saw the two gates.

Fortunately, the gate switch was good.

"A02, where do the two gates lead to?" He Ao asked. "Both gates lead to the core control room. According to calculations, the route of the right gate is shorter and more dangerous, while the route of the left gate is longer and safer." A02 replied. "Can the map of the two gate routes and the names of all laboratories or areas along the route be displayed?" He Ao asked quickly. "Yes." With this promise, a three-dimensional map appeared on the display screen. The two routes passed through this three-dimensional map. The laboratories and areas along the way were marked with names in Middle-earth characters. Some characters that seemed to be unknown to A02 were replaced by '□'. He Ao's eyes quickly scanned the map, and soon, his eyes stopped at the name of a laboratory, 'Research Institute of Space-Time Coordinates and Spacecraft Power' At this time, he also arrived in front of the gate, and he suddenly pulled the gate switch. At this time, Ye Yun also closed the distance with him. The sound of the huge robot moving was still following them. "Let's go to the right." He Ao looked at the gate that opened quickly, turned around and said quickly. This switch controls two gates at the same time, so the gates on both sides are open. This gate opened very quickly, and it was half open while he was talking. The sound of the huge robot was getting closer and closer. He Ao immediately rushed to the gate on the right. "Okay!" Ye Yun, who was following behind him, responded at this time. But just as he was about to follow He Ao's footsteps and rush into the gate on the right, a huge mechanical palm quickly fell from the sky, pierced through the ceiling in front of him, and grabbed him. At this time, the gates on both sides were fully opened and gradually closed. Ye Yun glanced at the blocked road ahead, and then suddenly jumped to the left. Before the gate on the left was about to close completely, he jumped into the gate. Boom---The gates on both sides were completely closed. The huge palm grabbed nothing and lifted it up. At this moment, no new attack appeared again. A02's speculation was correct.

But He Ao and Ye Yun entered different gates respectively. He Ao glanced at the gate switch on this side and found that it had been destroyed and could not be controlled with the mechanical core ring.

The two gates are in an inverted 'V' shape. There is a small window on the gate, and you can see the corridor behind the gate, and you can vaguely see behind the other gate.

Standing behind the small window, He Ao could see Ye Yun behind the small window of the gate on the other side.

At this moment, Ye Yun was sticking in front of the small window, talking and comparing to He Ao.

He Ao couldn't hear his voice, but through the shape of his mouth, he roughly understood his words:

‘My switch here is broken. See you in the core control room. Pay attention to safety. ’

He Ao looked at him and said, 'Be safe. ’

Ye Yun nodded.

The two turned around almost at the same time and looked towards their own road.
