National Development: I Build A Base On The Rock Beast

In the solar system, all the major planets are under intense construction, but still cannot meet the expansion needs, so humans have set their sights on the vast asteroid belt between Mars and Jupiter. Anyone who passes the test can get a pioneering rocket issued by the Earth Alliance and go to the asteroid belt to build their own base. After successfully building a star port-level development base, Duan Ming became a master, having equal dialogue with the entire top management of the Ground Alliance and being admired by tens of billions of people. While everyone was scrambling to choose a larger asteroid, Duan Ming, who had a contract evolution system, chose an interstellar creature to build a base on the Fire Rock Beast! You start with a rock beast, which controls the body of the rock beast to grow various building modules, and flies to the precious ice mineral belt to mine fuel minerals. There is also the Zerg Queen... The contract evolves the cnidarian turret and becomes a fully automatic close defense system. Three hundred poisonous stings are fired every second, crushing all incoming enemies!
