As he continued to advance, looking at the first-order late-stage zombies that occasionally appeared on the road, Ye Feng's face was unprecedentedly ugly.

Seeing these late-first-order zombies, the rest of the team may just think that these zombies become stronger very quickly, and those late-first-order zombies they encounter are much more difficult to fight.

However, with Ye Feng here, they wouldn't feel too worried. Because in a few days, they will all be able to advance to the late stage, and even break through to the second order.

However, Ye Feng had a completely different idea from them. Because in the previous life, it would take at least half a month, that is, fifteen days after the outbreak of the end of the world, for zombies in the late stage of the first order to appear.

But in this life, these zombies actually evolved to the late stage of the first order in just the tenth day. What this means, no one knows better than Ye Feng.

In the last life, due to the half-hour preparation time, although the local troops suffered heavy losses, they were not without the power to counterattack.

Even at the beginning of the apocalypse, it was possible to build a survivor base in every city.

However, as the zombies continue to become stronger, and humans are limited by talent, many people can only stop at the fifth and sixth order evolutionaries, or even lower.

So in the late apocalypse, under the impact of corpse tides again and again, some small and medium-sized survivor bases in major cities have been wiped out.

In the end, only the ten major bases, relying on numerous survivors and high-tech weapons, can barely survive.

Originally, Ye Feng thought that if he developed according to the process of the previous life, then he would have plenty of time to become stronger.

Before humanity is at a disadvantage, find a way to go to New York and destroy the vector of the disease, then he can change the pattern of the earth in this world.

However, what happened today told him that things were far from being as simple as he imagined. The accelerated changes of the zombies made everything he knew confusing.

even made Ye Feng afraid of the future.

If the evolution of zombies accelerates, will there still be a future for humans?

Even if it were those ten survivor bases, how many could be left?

Or is it the destruction of all mankind?

"Actually, I should have found out a long time ago." Ye Feng clenched his fists, but there was a deep sense of powerlessness.

As soon as they left the hotel, on the third day of the outbreak of the end of the world, they encountered zombies in the late first order.

And after leaving the Public Security Bureau, they even encountered a second-order predator, and it was the sixth day of the outbreak of the end times!

At first, Ye Feng just thought that this was a special case, it was the luck of these two zombies that swallowed a large amount of flesh and blood, thus accelerating their evolution.

However, Ye Feng found that he had neglected a little at this time. After zombies consume a large amount of flesh, it can indeed greatly accelerate their evolution.

But there is a limit to such acceleration, and it is impossible to exceed three times the normal speed at the earliest.

And when he left the hotel on the third day and encountered that late-stage first-order zombie, if Ye Feng hadn't been able to reverse his strong mentality, and his confidence had skyrocketed after obtaining the evolution box, he should have paid attention to these details.

According to the speed of three times, it can be calculated that the time for the appearance of first-order late-stage zombies should be on the ninth or tenth day.

And if they extrapolate according to this line of thought, they encountered a second-order mutant zombie on the sixth day.

In other words, the time for these zombies to evolve to the second order is not a month after the apocalypse. But around the eighteenth day!

Thinking of this, the cold sweat on Ye Feng's forehead flowed down suddenly.

No one knows better than him what the terrible consequences this will be.

Zombies are a species of strict rank, and high-level zombies have the ability to command low-level zombies.

For example, the second-order predator he encountered at the beginning, with a roar, he called all the zombies on the nearby streets.

Therefore, after the birth of second-order zombies one after another, under their call, it will be easy to form a wave of corpses and launch an attack on those survivor bases.

However, the appearance of a corpse tide a month later and the appearance of a corpse tide on the eighteenth day are two completely different concepts.

If nothing else, there is a huge gap in the level of perfection of the defense measures of the survivor base alone. Or in a day, one more trench can be dug and the wall can be built one meter higher.

If there was really a rush of corpses on the eighteenth day, the consequences would be unimaginable.

It may be fine for medium and large survivor bases, but for some small survivor bases, this can definitely bring them devastating disasters.

And the survivor base in Xin'an City is a small survivor base.

In the previous life, according to the information found by Ye Feng, the survivor base in Xin'an City was destroyed after two months, but it is difficult to say whether it can survive twenty days this time.

At this moment, Ye Feng felt unprecedented pressure.

Although Ye Feng didn't know why the time for these zombies to be promoted to the middle stage was normal, the time to be promoted to the late stage suddenly accelerated. But now that the zombies are changing at an accelerated pace, he has to face it.

Ye Feng pinched the evolution box hanging around his neck, maybe the answer was on this, but he didn't have the ability to explore it now.

"Speed up, you must arrive at the survivor base in Xia City within three days." Ye Feng's eyes gradually became resolute, and he ordered in a deep voice.

Now there are only eight days left for him, and there is no room for him to move forward slowly like before, and everything must be accelerated.

If possible, Ye Feng really didn't want to waste time and go to the survivor base in Xia City.

But among the survivor bases in Xia City, there is a brother that Ye Feng must find, and that is the Dragon Tooth Clan, one of the five pillars of the mechanical manipulator - Wu Ming.

Eagle Eye, Mouse, King Kong, and Manipulator are all brothers of Ye Feng's previous life, friends of life and death.

And in this life, of course, Ye Feng wants to get these brothers back one by one.

Ye Feng went to Xin'an City in his last life, and on the way to find his parents, he met the manipulator-Wu Ming in the survivor base of Xia City, and also obtained a lot of favors from the other party.

Although Ye Feng didn't know whether Wu Ming was already in the survivor base in Xia City during this time period, he had to look for it no matter what.

……

After Ye Feng gave the order to speed up the advance, although everyone was a little unclear, they also sped up one after another.

Of course, this result directly led to the fact that everyone in the training had a feeling of exhaustion and prostration.

If it weren't for the evolutionary flesh in the body, in this kind of high-intensity training, which could provide them with a steady stream of energy, these people would not be able to persevere at all.

And among all of them, the most dazzling is Sun Xue.

Except for Ye Feng, the rest of the people were all in the middle of the first order. And Sun Xue's physical strength before was almost at the bottom.

But today, Sun Xue's strength and speed can almost be compared with Xu Wenjie, a strong man.

Such a change, how can it not surprise everyone in the audience.
