The swarthy mouth of the cave seemed to lead to an endless abyss. The robot body where Wu Tian's consciousness was located walked in a spiral downward passage, and under the guidance of the micro-flying machine, it entered the underground base of Antarctica, which the outside world could not peep at.

If it was just trading knowledge materials, Wu Tian could do it outside the base. But if it is a physical transaction, Wu Tian had better come down in person.

"I have a copy of the core technical information of more advanced robots and mechas, and I need some items that can quickly improve my mental energy and physical fitness." In the brightly lit and empty hemispherical underground space, Wu Tian looked at the circular platform in the center of the underground space that was two meters above the ground like an altar, and said his request.

On the altar, a two-meter-tall illusory figure condensed by white light stretched out his hand, and the hard disk in Wu Tian's hand flew towards the altar under the traction of an unknown energy.

After reading the technical information brought by Wu Tian, the white illusory figure seemed to be very satisfied and said, "I can meet your requirements." However, in order to open a spatial portal, a lot of energy must be consumed. Therefore, although we can provide drugs that can quickly improve mental energy and strength, we can only provide a limited number of copies, and it is impossible to provide them in large quantities. ”

"No, I only need two copies in a short period of time, and I hope that the medicine you provide has no side effects and is worthy of the value of technical information." Wu Tian put forward a new demand.

"Are you sure you only need two?" The white projection of the God's Descent Heavenly Dome asked.

"I'd rather lack than excess, I just want high-quality products." Wu Tian replied.

"If it's better to have less than to overuse, why not a share?" Godseed Sky Dome asked.

"I'll give one of them to my subordinate scientific research institute to make sure that the drug you give has no side effects." Wu Tian said bluntly.

"It's a pity that I only have one high-quality medicine in my hand, I don't know if you dare to take it." The Divine Descent Heavenly Dome replied.

"Are you afraid I'll test the ingredients of the drug? But what I want to tell you is that if there is only one drug, then the drug will be handed over to the subordinate scientific research institute for research. I will only take it if I am sure it is safe enough. Wu Tian replied categorically.

"Humanity, we need more trust between us." Divine Descent Heavenly Dome said.

"Trust is built on understanding each other. For those who don't understand, blind trust is called blind obedience. Wu Tian replied.

"Human, I can feel from your consciousness that we share a common goal. That's why I chose to work with you. Otherwise, it would be impossible for the Godborn to cooperate with rebellious humans. Divine Descent Heavenly Dome said seriously.

"What you said may be true, but you must have missed a lot of important things. If you don't have tremendous external pressure, how can you, as a godborn, cooperate with me? Wu Tian replied.

Divine Descent Tianqiong didn't explain anything to Wu Tian, but just sighed and finally agreed to give two medicines.

With the strong energy fluctuations in the center of the circular altar, two black beads, one large and one small, appeared out of thin air, and then floated and flew towards Wu Tian outside the altar.

"This is the Qiangshen Pill, the small one is a secondary Qiangshen Pill refined from the failed variety, except that the medicinal effect is weaker, the ingredients are no different from the large Qiangshen Pill. If you have more advanced technical information, you can use the information to exchange more powerful elixirs or other medicines with me. With that, the white shadow of the God's Descendant Heavenly Dome disappeared above the altar.

In the flying machine, Wu Tian put a small secondary strong god pill in Ji Ya's hand, and he swallowed a large strong god pill in one bite. There was no so-called examination study, Wu Tian ignored the possible side effects of the drug and chose to take the risk of swallowing it directly.

There was no need to check the safety of the drug at all, and Wu Tian simply recognized the Qiangshen Pill with a strange pattern on the black marble-like surface in his hand. These strong god pills were not refined medicines at all, but inner pills obtained from the body of the miracle star beast! The reason why there is a difference in size is because the inner dan of the alien beast is large and small.

Feeling the surging energy in the alien beast's inner pill, Wu Tian knew that with his current spiritual energy, he couldn't withstand the surging energy in the inner pill at all, but Wu Tian still swallowed it without hesitation!

As Wu Tian expected, not long after the alien beast Neidan was swallowed by Wu Tian, wisps of energy seeped out from the Neidan.

"Sure enough, it is the legendary rune bondage, and it is precisely because of the rune bondage that the surging energy in the alien beast Neidan did not burst out all at once." Feeling the changes that seemed to be faintly occurring in his body, Wu Tian motioned for Ji Ya to also swallow the small No. 1 Alien Beast Neidan in his hand.

As time passed, Wu Tian's spiritual energy was steadily strengthening, and the strength of his body was also constantly improving. During this period, in order to provide the body's needs for energy and various essential elements of the human body, Wu Tian and Ji Ya both had drips on their arms.

With the energy support of the Alien Beast Inner Pill and a steady stream of potions to provide the necessary energy for the body, Wu Tian and Ji Ya quickly strengthened their body tissues and the most important spiritual strength in the feeling of high fever!

Ten hours later, as the high fever gradually subsided, the first round of reinforcement between the two was finally over! Now, the spiritual energy in Wu Tian and Ji Ya's bodies has reached the upper limit that their bodies can currently accommodate. In order to continue to absorb the energy in the alien beast Neidan in their bodies, the two of them must first improve their control over the spiritual energy. And the method of improving spiritual energy is a step-by-step cultivation for Ji Ya, and for Wu Tian, it is to separate more spiritual energy to descend on the alien planet! After all, with less spiritual energy in his body, Wu Tian's existing body could control the spirit in his body relatively freely. When the body gradually became familiar with the surging spiritual energy in the body, and when Wu Tian's consciousness outside returned, the mental control ability was further strengthened, and the second stage of strengthening should begin.

Based on the total amount of spiritual energy in his body alone, Wu Tian had already entered the level of a two-star interstellar mercenary. The time consciousness can stay outside has also been extended to two weeks!

"Ji Ya, the matter on this side of the earth will be handled by you, and I will be stranded on the alien planet for about two weeks before I can come back." Wu Tian, who was in great spirits, had come to leave the earth again.

"Don't worry, Ah Tian, I'll take care of things on this side of the earth, I've been teaching myself business management and psychology recently!" Ji Ya assured Wu Tian.

Nodding hard, Wu Tian finally said, "In case of an unexpected change of force majeure, even if it is completely exposed, it is nothing." You must remember that you can stay in the green mountains and don't worry about running out of firewood! ”
