Chapter 3664 Pure

For the next half a year, Xu Yi was busy. After more than half a year of practice, his skills in searching for Xuanhuang evil veins became more and more sophisticated, and he collected a lot of Xuanhuang evil veins.

In the words of Qin Bing, who temporarily took over the post of tower envoy, the Gray Killing Tower has collected more Xuanhuang evil spirits now than in the past ten years combined. There is absolutely no suspense in winning the first place this time.

That evening, Xu Yi controlled the Gray Killing Tower and saw another starry sky beast. It was a starry sky multi-legged three-eyed beast, huge in size, swimming lazily in the starry sky.

Huge tentacles passed near the Gray Killing Tower. Even though Xu Yi controlled the Gray Killing Tower to retreat quickly, he was still inevitably blocked by the tentacles, causing the entire Gray Killing Tower to completely lose control and spin several times in the starry sky.

But the giant beast didn't feel anything and still swam forward unsteadily.

After the huge body completely floated past, it brought up a galactic hurricane.

Xu Yi regained control of the Gray Killing Tower and easily withstood the violent hurricane.

He suddenly remembered the little wolfdog, whom he hadn't seen for many years. The little wolfdog had taken over the body of Titanosaurus and must have entered the starry sky, but he didn't know if it was on the ancient starry sky path.

After much experience, Xu Yi started to worry about the little wolfdog.

Judging from the body of the titanosaurus python occupied by the little wolf dog, it should be just a young python. Placed in this vast airspace, it is really not a terrifying beast.

He could only wish the little wolfdog good luck and hope he could meet him again in this life.

After looking at the main observation deck for a moment, Xu Yi handed over the control of the astrolabe to Qin Bing.

In the past six months, he has been busy and has never had a good rest.

Now, he has collected enough Xuanhuangsha to the extent that he can securely win the first place even if the other party plays tricks, so he has given up the idea of ​​continuing to toss.

Later, Xu Yi hid in the secret room. After sleeping for three days, he got into the four-color seal space.

In the vast and clear space, Xu Yi took out a black bottle. Then he removed the cork, turned the bottle over, and poured out a cloud of black and yellow miscellaneous gas.

When the miscellaneous energy overflowed, he collected Yunhe's pure energy and allowed the four-color seal space to decompose the black and yellow miscellaneous energy.

Yes, these Xuanhuang miscellaneous gases are exactly the Xuanhuang evil spirits he collected. There are many Xuanhuang bottles in the Xuanhuang Tower, which can be specially used to collect Xuanhuang evil spirits. Many officials have these things.

A bottle of Xuanhuang Sha can be sold for two pieces of Xuanhuang Essence.

Every time Xuanhuang Sha is collected through Xuanhuang Storm in Xuanhuang Tower, many immortal officials will take advantage of the situation to collect some Xuanhuang Sha. Although this is an explicitly prohibited behavior, almost all tower owners will turn a blind eye and use it as an opportunity to give benefits to their subordinates.

Xu Yi also did not prohibit it, and because of his excellent ability to find the Xuanhuang evil energy, everyone in the Gray Killing Tower made a small fortune by relying on the gathered Xuanhuang evil energy.

Of course, Xu Yi used the Xuanhuang bottle to collect the Xuanhuang evil spirit, not because he was so greedy that he would not let go of the three melons and two dates, but because he wanted to try to use the decomposition ability of the four-color seal space to decompose the Xuanhuang evil spirit. If these four It would be wonderful if the Color Seal Space could successfully purify this black and yellow evil spirit.

Time passed little by little, more than an hour passed, and Xuanhuangsha didn't change at all.

Xu Yi waited for another hour and gave up completely.

After thinking about it carefully, he felt relieved. Originally, this Xuanhuang evil was a natural thing, not a mixture, and could not be purified, which was reasonable.

Immediately, he took out a round bead with a dark yellow color and a turbid texture. Yes, this was exactly a dark yellow bead.

Xu Yi's official position was not enough to be issued Xuanhuang beads, but with Suijie's status, he could receive several Xuanhuang beads every year.

However, Suijie was promoted to general for a short period of time, and it was not yet time for the Xuanhuang beads to be distributed.

The black and yellow beads in his palm were captured when he raided Shan's family hall. He didn't get many, so he only got three.

He let go of Yunhe Qingqi and exposed the Xuanhuang Pearl to the decomposition ability of this clear space.

Within a moment, the Xuanhuang Pearl started to react. Xu Yi was very happy and stared closely at the changes in the Xuanhuang Pearl.

Soon, the black and yellow beads dispersed into streaks of mist, and slowly the smile on Xu Yi's face disappeared.

He clearly found that the black and yellow beads turned into a wisp of black and yellow evil under the tossing of the four-color seals.

In any case, this Xuanhuang Pearl is condensed from Xuanhuang Sha. It was purified by powerful monks who used their magical powers to remove the impurities in Xuanhuang Sha.

He was counting on the four-color printing space to be further purified.

But he never dreamed that the four-color seal space was so weak, and a reverse purification came. He was very depressed, and when he was about to finish the work, he was surprised to find that the wisp of black and yellow evil formed by the black and yellow beads began to vibrate, slowly overflowing with colorful colors. The lines finally condensed into a cool black and yellow mist.

"This, this..." Xu Yi was stunned.

The black-yellow mist was very similar to the black-yellow gas he had transformed from the black-huang essence, but the black-yellow mist was much purer than the black-yellow gas created by the black yellow essence.

"This, this is Gu Xuan Huang Qi, pure Gu Xuan Huang Qi."

Huangmei shouted excitedly, "Why do you have to refine into the Xuanhuang Sha when you reach the first level of Taoism? It's for this pure ancient Xuanhuang Qi.

Because the Xuanhuang Qi produced by Xuanhuang Essence is far from comparable to this thing.

The key point is that while the Xuanhuang Pearl provides ancient Xuanhuang Qi, it also provides impurities that are extremely difficult to refine.

That's it, you use the four-color seal space to directly refine the ancient black and yellow energy. "

Xu Yi was very excited, "I've made it, I've made it..."

"What a fart."

Huangmei curled her lips and said, "Although your four-color seal created the Ancient Mysterious Yellow Qi, this wisp of Ancient Mysterious Yellow Qi accounts for about one percent of the Ancient Mysterious Yellow Qi that a Black and Yellow Bead should have. Based on the fact that you have created the Mysterious Yellow Bead now, To reach the second level of Domain with this ancient Xuanhuang Qi at such a speed, you will need at least one or two thousand Xuanhuang Pearls, and with your income, you can save them for thousands of years."

Xu Yi was stunned, and then comforted himself, "It is better to be able to purify it than not to be able to purify it. As for the matter of getting the mysterious yellow beads, let's wait and see in the future."

At that moment, he inhaled the wisp of ancient black and yellow energy into his body. There was no need to deliberately refine it at all. The ray of ancient black and yellow energy dispersed directly into the limbs and bones, and then returned to the spiritual platform. The two golden realm roots in the life wheel trembled slightly, as if they had a serious illness. repair.

Xu Yi was so happy that his soul trembled. At that moment, he refined the remaining Xuanhuang beads into ancient Xuanhuang gas and inhaled it into his body.

Sure enough, as Huang Mei said, the ancient Xuanhuang Qi formed by the three Xuanhuang Pearls could not produce any intuitive benefit to the two golden domain roots.

However, Xu Yi was satisfied with the discovery of this change, and then he escaped from the four-color seal space.

In the evening of that day, an order from the top came from the Gray Killing Tower, saying that the one-year period had come, and all the tower owners were required to return and review what they had gained.
