After leaving the abandoned cement factory, Yang Zheng left the sphere of influence of the Nanhua County defense base non-stop, and went straight to the northwest.

When he was in a hurry, whenever Yang Zheng's energy ran out, he took out a few werewolf energy hearts from the storage bracelet to replenish his energy, so that he could continue to hurry with full understanding.

Because of his previous dangerous encounters and experiences, along the way, Yang Zheng deliberately avoided those towns and specially selected some relatively remote and barren mountain roads to advance.

After this day and night, Yang Zheng left the boundary of Lingnan Province and then entered Guixi Province, and it took him another ten days before he crossed the boundary of Guixi Province without danger and smoothly entered the territory of Southern Yunnan Province.

Along the way, Yang Zheng didn't find a real survivor at all, no matter where he went, everywhere was desolate and silent, even some small animals that were common before, he rarely saw them, and he didn't know where to hide.

Sometimes, when he walks alone on the deserted highway, there will always be a trace of sadness in his heart, feeling that he has been abandoned by the whole world.

In this way, unconsciously, 27 days passed, and finally, on the afternoon of the 28th day, Yang Zheng's lonely figure appeared in a small village on the edge of the Lancang River.

The small village is still dozens of miles away from the Lancang River, and the village is desolate and rotten, full of messy household garbage and rusty cars.

After entering the village, Yang Zheng found a safe and hidden basement to hide, and planned to wait until it was dark before finding a way to cross the Lancang River.

The northwest border of southern Yunnan Province is the Lancang River thirty miles away, if Yang Zheng crosses the river from this place, the other side of the river is Shuzhong Province, one of the seven northwestern provinces, at present, what is the situation in Shuzhong Province, Yang Zheng is not clear at all.

Everything can only be clarified after he crosses the river tonight.

After a month of wandering over the mountains and mountains, Yang Zheng is now desperate to cross the Lancang River to see if it is really as the overlord of Chu said, and has not yet fallen.

After finding a place to hide for the night in the village, Yang Zheng came out again, and he had to find some food to fill his stomach before the sun went down.

It is now difficult to find food to satisfy hunger behind the street shops on the side of the highway, because most of the food has spoiled and spoiled due to time.

Therefore, within a month of arriving here from Lingnan Province, Yang Zheng basically made a living by hunting and fried fish.

Fortunately, everything he did was done during the day, so the mutant monsters hiding in the wild couldn't find out about his existence.

In a ditch that is not very wide, Yang Zheng threw a few grenades into it, and suddenly, after a few loud "booms", the water splashed into the sky, and when the water surface gradually calmed down, after a while, there were dozens of wild fish, large and small, slowly surfaced.

Yang Zheng screamed excitedly on the spot, he quickly stripped naked, jumped into the water, picked up all the fish floating on the water, and then began to light a fire on the shore to prepare dinner.

Since the beginning of last year's catastrophe, the number of some birds and animals in the wild seems to be getting smaller and smaller, but the fish in the water, on the contrary, they are breeding more and more, and their size is also getting bigger and bigger.

To be able to walk here smoothly, most of Yang Zheng's food comes from wild fish in the ditch.

After dinner, the sun gradually set, and at this time, Yang Zheng got up to clean up the mess of the scene, and quickly rushed back to the hiding place in the village.

After hiding in the remote basement, Yang Zheng looked at the time and found that it was only half past six in the afternoon, and he was going to wait for twelve o'clock in the middle of the night to quietly cross the Lancang River.

If daylight passes, he is afraid that there are survivors' troops stationed on the other side of the river, and if he is discovered at that time, it is likely to arouse the suspicion of others.

In the basement, it was a little damp, and Yang Zheng put some rain cloth sacks on the ground, so that he could lie on it relatively clean and comfortable.

Lying on the ground, with nothing to do, Yang Zheng opened the storage bracelet and prepared to take out the energy hearts stored in it to continue to absorb energy.

After a month of uninterrupted absorption, there were originally more than 600 energy hearts in Yang Zheng's storage bracelet, but now, there are less than 50 left.

It is also strange to say that when he was in Area 9 of the Nanhua Defense Base before, the X-90 mutant gene in Yang Zheng's body could only absorb a few mutant werewolf energy hearts at most every day, and now he can consume at least more than twenty energy hearts a day.

Like the fifty energy hearts left in front of him, it is estimated that in less than three days, Yang Zheng will be able to consume them all.

At the same time, what made Yang Zheng even more strange was that the eight mutant elephant people's blood-colored energy hearts he obtained in the abandoned cement factory a month ago seemed to be different from those mutant werewolf energy hearts.

The energy hearts of mutant werewolves, as long as Yang Zheng put them in the palm of his hand, the X-90 mutant genes in his body were like gluttonous cats that smelled fishy, and they frantically poured out of the body, absorbing them in an instant.

However, no matter what method Yang Zheng used, the X-90 hidden in his body didn't seem to be interested in them at all.

This result made Yang Zheng not puzzled, in the past month, Yang Zheng was puzzled by this problem most of the time.

He couldn't figure out why the energy hearts of these eight mutant elephant people contained much more energy than the mutant werewolves, but why did the X-90 in his body be indifferent to them?

Thinking of this, Yang Zheng once again took out a mutant elephant man's blood-colored energy heart and put it in the palm of his hand, although it has failed after countless experiments, but tonight, Yang Zheng still wants to continue to try again, to see if the X-90 in his body reacts to the blood-colored energy heart in front of him.

The blood-red energy heart was quietly placed in the palm of his left hand, on top of the translucent crystal, and the blood-colored streamers were circulating everywhere, looking extremely gorgeous.

Yang Zheng took a deep breath and tried his best to control the X-90 mutant genes in his body, ordering them to gush out of his body and gather in the palm of his left hand.

In an instant, the silver-white metal liquid, like a swimming silver snake, quickly spread towards Yang Zheng's palm.

However, these silver-white metal liquids, as if they were not interested in the blood-colored energy heart in the center of the palm, automatically avoided them to both sides every time they passed by the blood-colored crystals.

"Hey...... Or is it the same as before, what the hell is going on? ”

Yang Zheng frowned, and slowly put this blood-colored energy heart in front of his eyes, wanting to take a closer look at what was abnormal, why would X-90 be indifferent to them?

After observing for a long time, Yang Zheng didn't come up with a reason, and finally, he lowered his head and thought about it, and a strange idea suddenly popped up in his mind. "Could it be that the surface of this blood-colored energy heart has a layer of defensive crystals, causing the X-90 in the body to feel the energy contained in it?"

Thinking of this, his heart moved, and he immediately decided to crack open a blood-colored energy heart to experiment and see if there would be any surprising discoveries.

Yang Zheng gritted his teeth violently, took out a hammer from the storage bracelet, and smashed it towards the blood-colored crystal.

"Bang!!"

On the spot, this blood-colored energy heart was smashed open a few cracks, and suddenly, Yang Zheng suddenly smelled a strange fishy smell, emanating from the cracks of the blood-colored crystal, but at this moment, something surprising happened.

In an instant, the X-90 mutant gene hidden in Yang Zheng's body, as if it had been stimulated by distance, swam wildly in his body, and then, Yang Zheng was shocked to find that a stream of metal liquid as thin as silver threads poured into his body uncontrollably, and quickly surged towards the blood-colored crystals on the ground......
