"Old Xie, look at how much time you will need if you complete this project." Wang Chen asked Super Brain No. 4 to draw a pair of engineering drawings and handed them to Xie Rong, and then said.

On this engineering drawing is a tunnel nearly fifty kilometers long, and this tunnel is the passage that connects this place to the secret base in the future, which is Wang Chen's new task for the Xie clan.

"Even if there are gold-eating beasts to help dig the tunnel, it will take more than three months for our people to work overtime." Xie Rong replied cautiously, for fear of upsetting Wang Chen and cutting off their food source.

"Didn't you just say that the gold-eating beast has a very strong digging ability, why does it take so long?" Wang Chen asked a little puzzled.

"If the gold-eating beast digs with all its might, it can dig about two kilometers a day, but the residue from the excavation tunnel needs to be pulled out by cart and poured into the magma pool for ablation, which will take a lot of time." Xie Rong explained.

"In other words, if you have large loading equipment and transport vehicles, you can build about two kilometers of tunnels a day?" Wang Chen's eyes lit up after hearing this, and asked.

"As long as we can quickly remove the debris excavated by the gold-eating beasts, and we work around the clock, we can build at least three kilometers of tunnels a day." Xie Rong patted the "sternum" and said.

"If that's the case, that's going to be easy! So, you find a few people with a little more brains, go to the gate and wait for me, and I'll get some big equipment in a little bit, and I'll teach them how to use it. ”

Wang Chen is going to transfer his consciousness to Earth to get a batch of loaders and slag trucks, and with the help of these equipment, they will definitely be able to greatly speed up the progress of digging tunnels.

However, for the sake of safety, he still decided to go back to the gate first and close the gate before transferring consciousness, after all, the heart of defense is indispensable, he doesn't want to go back, and he can't come over

After half a month, Wang Chen returned to the secret base again, and to Wang Chen's surprise, Wang Jinxuan and Bai Xue actually went out hunting together, which made him miss a little unable to find a place to sustenance.

That's it, who knew that the other people who stayed in the secret base looked at him as if they were ignoring him, and even after Jiang Weijia pestered him to release the big stupid bear, he took the big stupid bear aside to play and threw him there alone.

After he handed over the wolf fox to Xu Cheng, he could only return to his room in a gloomy manner, but fortunately, Wang Jinxuan would irrigate the banyan tree every day for half a month, and now it has grown to a height of more than one meter, and it has finally regained consciousness, which allows him to finally find a person to communicate with.

However, before communicating with the Banyan Tree Consciousness, Wang Chen spent 10 million experience points to get No. 4 to start the transformation process of the energy system, after all, this process takes a day, and he can't use the hunter skill within this day, so the sooner the transformation, the better.

"In such a short period of time, not only have you become so strong, but you have also kept your promises, I really didn't misunderstand you, choosing to cooperate with you is definitely the most correct decision in my life." After Wang Chen came back to his senses, the banyan tree consciousness communicated with him through consciousness.

"Huh! It's just mutually beneficial, but there are really some things I want to help you with this time, can't you control the growth of your body? Is there a way to grow some leaves on the rhizomes to send oxygen into the underground tunnels? Wang Chen asked to the banyan consciousness.

"As long as there is enough life energy, this can be easily done, but the energy in the life source stone is not endless, are you sure you have to consume so much life energy to do this?"

"Then do you know how the Life Source Stone replenishes energy?"

"The Life Source Stone is actually a converter of life energy, which converts and absorbs the life energy of dead creatures, and then releases these life energies to living creatures, and so on. So to replenish its life energy, it only needs to be close to the dead creature. Banyan replied.

"Oh? It's that simple? Wang Chen asked with some surprise, he thought that he needed some harsh conditions.

"It's really simple for it, but apart from it, even the advanced beings in the nine-dimensional universe can't do this, so it's not simple at all." At this point, Number 4 spoke to him through consciousness.

"Looks like I've really picked up a treasure!"

After understanding the function of the life source stone, Wang Chen took out the life source stone, and took out a corpse from the space package, only to see that as soon as the corpse appeared, it emitted a little starlight to converge on the life source stone, and soon these starlights became more and more, and the corpse quickly dissolved, and in the end, there was no hair left except for clothes.

"This is the most basic law of nature, nature makes life conceive, born, and grow, and life returns itself to nature after death, and the source stone of life is the embodiment of nature, so it can convert and absorb 100% of the dead biological energy." After the body disappeared, Banyan Tree Consciousness said.

After listening to the words of Banyan Tree Consciousness, Wang Chen was no longer entangled, is this just cannibalism in disguise? Directly take out all the bodies in the space package, and let the life source stone be converted and absorbed.

Although this conversion is indeed suspected of cannibalism in disguise, since those people have died, they will eventually return to nature, and now being absorbed by the incarnation of nature, the Life Source Stone, represents the complete end of a life, and the life energy returned by that life will be used by the Life Source Stone to help other creatures.

This is the same as the richest man on the earth who drank feces to extract pure water, can you say that he really drank fecal water? In fact, as long as you pass the hurdle in your heart, this is just a normal thing.

Of course, if there is still a normal water source, he won't drink that kind of water if he kills Wang Chen, because there is no benefit! But the water emulsion of the life source stone is different, this is a good thing to prolong life and promote evolution, how can he not drink it, isn't that stupid?

Therefore, the living environment is the easiest way to change a person's way of thinking, and he has survived for a few months in the last days of Blue Star, and at this time he has also begun to think about problems with the way of thinking of people in the last days.

Soon after the Life Source Stone converted and absorbed all the corpses, Xu Cheng knocked on Wang Chen's door, it turned out that his experiment today had come to an end, and came over to ask Wang Chen what to do with the wolf fox.

"This still needs Uncle Dong's help." Wang Chen sat on the main seat of the stone table in the hall and said.

"Haha! Boy Chen, what do you want me to help with? It just so happened that Edelman Metal's experiment entered the neck bottle, so he took a two-day break to change his thinking. "It's better to be in time than to be in a hurry, Wang Chen's words dared to finish, and Dong Hua's voice came from behind him.
