"Elder Wu, I honor you as Elder Wu out of respect for you, but it doesn't mean that you can insult me as you please," Li Lang felt that this old man was really inexplicable, and the request was a bit rude, "Casually recognizing elders that's disrespectful to my parents, I'm already ungrateful, I don't want my father and mother to be unsettled in heaven too!"

"Cough cough, joke, joke, Xiao Li don't be so excited ah, come come come, I'll take you to visit my research base." Wu Tian after seeing Li Lang's reaction hastily snorted, sort of unveiling this matter over, only his eyes flashed a trace of regret, and some relief. Afterwards, he pulled Li Lang to stroll around the large test base.

Li Lang didn't notice anything, he just felt that this old man was really weird, but he just attributed this to all the eccentricities of geniuses. In fact, compared to some of the great scientists in history, this old unorthodox Wu Tian was still quite normal...

This research base was truly magnificent, and was described as very majestic. The entire base was divided into three levels, the three-dimensional structure was pyramid shaped, the further down the broader. The first level was where all kinds of conventional experiments were conducted. The second floor was refined and divided into a weapons area, a vaccine area, a catalytic area, and so on. Although there were no scientific researchers here, there were thousands of robots that could meticulously complete the experiments according to the instructions given by Wu Tian's old slut, and the final experimental data was analyzed and evaluated by the central light brain, and then sent to Wu Tian's face. Moreover, the centralized light brain belonged to the intermediate level artificial intelligence! This surprised Li Lang, because as far as he knew, there were only three intermediate AI lightbrain in the world, and none of the advanced ones. This Wu Tian's base was really not simple, and he didn't know what it was used for in the past.

During the tour, Wu Tian had restored all the alienated limbs of his hands to human, but the lower half of his body was still in the form of a horse. The large horse's hooves walked in the silver-white glowing metal corridors, making a strange sound, like horse hooves, yet a bit like drum beats.

Seeing Li Lang's puzzled gaze, Wu Tian smiled dashingly and said, "This lower half of my body but I can't take it back because I once devoured a level 6 zombie horse when I advanced to a level 7 zombie, so my body's form has also undergone a huge mutation."

"Zombie horse?" Li Lang couldn't help but be even more confused, could animals also turn into high-level zombies?

"It looks like you're drawing a blank on the entire zombie world, here's how I'll tell you what's going on." Wu Tian looked at Li Lang's perplexed look, and with another lewd flutter of his beard, he began the popularization education of the basics of the zombie world in his mouth...

Under Wu Tian's narration, Li Lang finally had a rough understanding of the entire zombie world.

There were more than six billion zombies in the world, and less than one billion of the original seven billion human beings were left cowering in various fortresses and bases. And most of these six billion zombies were gathered in the cities. Because of the huge base, as well as the rapid mutation of the zombies that escaped from the testing grounds in various countries, there were now quite a few high grade zombies. According to Wu Tian's own knowledge, at the very least, traces of grade 8 zombies had already appeared!

The narrative has been taken without authorization; if you see it on Amazon, report the incident.

"The T-virus of the first generation was spread through the air, and only after that did it become a blood-borne virus because of its rapid mutation, which is why the biochemical virus broke out so quickly within the globe."

And after the human zombies reached level five, they could almost comfortably take some small alienated limbs into their bodies, such as the Jiang Chu Han that Li Lang encountered that day. After reaching level six, it would once again possess intelligence, only that this intelligent zombie no longer possessed memories about humans, but only memories of being a zombie! So this kind of intelligent zombie is extremely scary, they only know how to kill madly, and extremely hate human beings, or rather, they hate any intelligent life!

This is actually nothing, after all, the human's attack power is insufficient, and there are internal conflicts, so they have always been on the defensive, while the zombies' huge numbers can destroy any attackers, but they can't enter the human's fortress. Therefore, humans and zombies could basically maintain a balance of power.

However, Wu Tian discovered a third force outside of humans and zombies, that is, mutated animals and insects. Because large animals are tougher, they are more adaptable to the T-virus than humans, so although there are not many large animals left, most of them can successfully evolve into high-level mutated beasts, and the top mutated beasts that have evolved to a certain degree will have intelligence, and can manipulate ordinary animals and zombies through some unknown methods. Then there are the insects, most of which have more or less produced some mutations and become an intelligent life in the form of a symbiote, and when the number of monads reaches a certain level, they will likewise evolve advanced intelligence.

"That is to say, on the current Earth, there are a total of four knowable forces: humans, human zombies, mutated beasts, and mutated insects," after Wu Tian finished speaking, he glanced meaningfully at Li Lang, "Even if I am a level seven zombie, I am insignificant in front of the group's power, so I have always been seeking for a greater power, and as you know, I have a dream..."

"Well, if you are insignificant, then I am not even more of a mole, I just want to know, what do you need me to do?" Li Lang said with a smile. The earth was in chaos, what did it matter to him? And he couldn't wait for the more chaos the better, so that he could fish in troubled waters and maximize his benefits. Moreover, his current power was too weak, Wu Tian needed power, why wouldn't he need strong power?

"You just need to accompany me every day to talk and give me a hand to help out, it can be considered as fulfilling the wish of a lonely old man." Wu Tian looked at Li Lang with a miserable face and said, this mournful gaze caused Li Lang to get goosebumps.

"Okay, okay, but I want you to fulfill a request of mine, to find someone within the fortress," Li Lang said calmly after agreeing, "Don't tell me you can't hack into the light brain systems of the various fortresses right now."

"Uh, sure, but not until you've been working for me for a while." Wu Tian, of course, agreed wholeheartedly, checking up on an individual wasn't a piece of cake, this was an intermediate level intelligent light brain ah.

"Alright, let's continue the tour below, I'm going to take you to a mysterious place." Wu Tian resumed his face full of lewd looks and said with a hefty smile.

They were going to the third floor of the base, which was a bit different from the two floors above, the whole place was radiating a soft green light, but the gate was engraved with three big black words "Food Garden". After completing the identity verification at the entrance, a huge metal gate opened, Wu Tian couldn't wait to walk in with Li Lang.

Subsequently, Li Lang found himself in a vegetable garden, the entire "food garden" was filled with rows and rows of one-person thick, two-meter-high cylindrical culture tanks, a careful count of almost a thousand of these things. Inside each of these tanks there was a tree-like thing, connected to a piece of tuber, just because of the green color of the culture liquid and could not be seen clearly.

Wu Tian mysteriously walked to the front of a culture tank with a red light emitting from the top and said with a smile, ''Uh-huh, this one is cooked. Are you hungry, Little Li?"

"Huh? Oh, it's okay." Li Lang could not help but be a little puzzled, I do not know what this old man engaged in so many culture tanks to raise, could it be that this old boy is a vegetarian? But if it's groundnut potatoes then little master won't eat it.

Only to see Wu Tian's hand swish into the biofilm of a culture tank, grabbed a round thing and yanked it out, handed it to Li Lang with a watery hand and said, "Eat it, don't be polite."
