Hong Yi got enough evolution potions and program cards, which can make some people's evolution level increase by at least one level, and for Hong Yi, this kind of thing is even more important.

The current Hong Yi is at the Silver Star level, and if he can continue to improve his evolution level, his strength will increase exponentially.

Unlike others, after Hong Yi opens a new brain domain, he can unlock a new skill tree, and his own skill tree has been finalized, and the skills he unlocks will be fire-based abilities.

After he returned, he immediately distributed a part of the evolution potion and program card, and then asked the horse to guard the door, while he himself entered a tent, ready to inject the potion that opened the second-level brain domain of the silver star.

As for Wu Tong and Yang Cheng, Hong Yi gave them full freedom, they could stay if they wanted, and they could leave if they wanted, but none of them left.

Everyone knows the current situation, there are almost no decent human forces outside, and if you want to survive in this dangerous and complex environment alone, the difficulty can be imagined, and you can only survive by staying.

Xue Ling helped deal with the outside affairs, she may have been stimulated by some kind of experience because of her previous experience, and the whole person has been in a state of excitement, constantly planning for the future, and deploying for the future. Hong Yi is so happy, this also saves her from thinking nonsense, and it's good that someone has to worry about these trivial matters for him, if he wants Hong Yi to deal with these things by himself, he doesn't have the time.

Inside the tent, Hong Yi checked his physical condition, and then did not hesitate to inject the evolution potion needed to open the second-level brain domain of the white star into his body, as for the program card. It has long been inserted into the brain of the biological adjutant.

Unlike other people, you need to think twice. For fear of failure, Hong Yi has no such concerns. His physical constitution is different from ordinary people, firstly because of his own great potential, and secondly, because he has reorganized his body through the Nirvana Sutra, and he does not need to worry about the negative effects of failure at all.

This time, the process of opening the second-level brain domain of Silver Star was very fast, and it only took ten minutes for Hong Yi to complete the opening of the brain domain.

At this moment, he is already a second-level evolutionary of the Silver Star, and his strength, agility and reflex nerves have increased by 1 point each. And it also opens up a talent skill.

Burn Mark.

This skill can ignite the target body, using some kind of brain wave, as long as it is in the body of a living being, there are substances that meet the combustion, this ability is to ignite the target, and it is definitely a terrifying killing move.

Even if he faced an opponent of the same level, as long as Hong Yi cast this burning mark, his body would immediately spontaneously combust, and the consequence would naturally be a dead end.

Just when Hong Yi was about to make persistent efforts to open the third-level brain domain of Silver Star. He suddenly felt some pain in his head, and the biological lieutenant Zhi Brain immediately gave an answer.

The speed at which he opened the brain domain in a short period of time was too frequent, which was a very huge burden on Hong Yi's brain, if he continued to open it. Apparently it can damage brain cells.

Even if the body is reorganized, it is still difficult to repair the damage caused by the fatigue of brain cells. Helplessly, Hong Yi gave up his plan. You can only wait for a while before turning it on.

However, for Hong Yi, he is now an invincible existence in the Silver Star. Even if you encounter a Silver Star Level 5 Evolver or a mutant, you have the power to fight, and you have a great chance of winning.

Xue Ling's plan for a counterattack on Acropolis No. 1 has been worked out.

Of course, these battle plans were completely formulated with Hong Yi as the center, but there is no doubt about the role of other people, it is necessary when fighting, and once the Acropolis is attacked, how to control the defense system, how to occupy a piece of area, all need manpower.

Among the people who defected to Hong Yi, there are many talents of this kind and that, some are good at formulating tactics, some are good at fighting, and some are good at logistics.

In the past, many of these people were elites, even rich people in rich areas, but now, they all work for Hong Yi for free, and in the slogan propagated by Xue Ling, only Hong Yi is the hope of mankind.

Yes, this sentence was not heard wrong at all, this is the slogan that Xue Ling came up with.

Only this kind of slogan, only by giving people this kind of hope, can we spread our prestige in a short period of time and recruit as many talents as possible.

The most lacking thing now is not materials, but people, because even if you occupy Acropolis One, if you want to control this place, or even have self-sufficient productivity, roughly calculated, you need at least 5,000 people.

And now they have only five hundred, which is far from enough.

For this kind of 'god-making' movement, Hong Yi feels that it doesn't matter, there are also benefits to fame and prestige, one is naturally what Xue Ling said, you can gather popularity and gather useful talents as quickly as possible, on the other hand, you can also let your former friends know Hong Yi's existence and find it yourself.

Because if you want Hong Yi to look for them by himself, he doesn't know how to find the Year of the Monkey Ma Yue.

Holding the various plans made by Xue Ling and several other tacticians, Hong Yi looked at it carefully, then put it down and said, "Xue Ling, thank you!" ”

"This is not only my own credit, other people have been giving advice day and night these days, we all believe in you, although we only have five hundred people now, but I believe that it will not be long before it will become five thousand, or even fifty thousand." Xue Ling stroked the broken hair in front of his forehead with his hand, and said with a remarkable demeanor.

Hong Yi can see that Xue Ling is seducing himself, but Hong Yi is not interested in men and women for the time being, although Xue Ling is a rare beauty, but Hong Yi always feels awkward, he used to be an ordinary friend, and suddenly a beautiful woman secretly sent Qiu Bo to herself, which is what Hong Yi can't accept.

Outside, the few large mutant beasts captured by the dragon mutant were enough for five hundred people, and there were also nutritional potions brought from the No. 7 gathering place, so there was no need to worry about food at all.

As for weapons, almost everyone had them when they fled, although they were of different styles and the quality was not guaranteed, but at least there were one or two pieces of manpower, and there were a lot of firearms, and there was no problem in arming five hundred people.

It's just that there are some troubles in the means of transportation, there are not many vehicles, only a dozen, and it is obviously impossible to pull everyone up, but fortunately it is not far from Acropolis One.

Everything is ready, according to the plan, everyone will arrive at the outside of the Acropolis No. 1 before dawn tomorrow, as long as Hong Yi breaks through the entrance, the others will immediately enter and clean up the mutants inside.

Everyone in the col was clearly ready, fully dressed, waiting for a battle that would mean something to them.

This is the first time that humans have counterattacked since the mutants began to attack the human gathering area, and although they are not official troops, they have also brought a great shock and shock.

If they succeed, it is conceivable that they will become heroes among the human survivors within a radius of hundreds of kilometers around.

The situation of Acropolis No. 1, Xue Ling had already asked people to investigate in advance.

Because of the special geographical environment, there are not many mutations around, the total number is only thousands, and the mutants in Acropolis No. 1 should be about this number, among which there are likely to be one or two big demon-level mutants, as for the demon-level mutants, the number will definitely exceed hundred.

Although he was very confident in Hong Yi's strength, Xue Ling was still very worried.

By the early hours of the morning, more than 500 people had already begun to march in the direction of Acropolis One, which used to be a forbidden place for humans at night, but now, in order to survive, humans have to be active in the wild, both day and night.

And they found that the night is not a dangerous and deathly situation, human beings did not dare to come out before, it was inertial thinking, and this inertial thinking is obviously the dross that needs to be discarded the most.

Mutants are also scared in the night, just like at this moment, a few wolf beast mutants peeking in the grass were immediately discovered in the night scanning mode of the adjutant brain, and then seven or eight sturdy men with sharp knives in their hands touched into the grass without saying a word.

Ten minutes later, they walked out, their bodies were full of blood, and a few people were only slightly injured, but the wolf beasts in the grass had all been slaughtered by them.

Hong Yi saw this scene really, he smiled, and I have to say that the mutant actually did a good thing.

They have driven humanity out of the cage where the man thinks he was safe, and all humans have to face the brutal wilderness, and the cruel reality will grind humanity like a whetstone, the unfit will be eliminated, and the strong will survive.

Although they only have five hundred people, the combat power of these five hundred people is stronger than a thousand people, or even two thousand people, not to mention, Hong Yi is still sitting inside, and it is precisely because of this that they will attack the Acropolis No. 1 with a mere five hundred people.

The first rays of sunlight in the sky have not yet appeared, and Hong Yi and the others have already reached the periphery of Acropolis No. 1.

The area chosen by Acropolis No. 1 is very steep, built on a mountain, and there are several walls built on the mountain in the city, which isolates the entire Acropolis No. 1 into many areas, and it can be said that among all the acropolis, the defense system of Acropolis No. 1 is the strongest. However, it is said that when the mutants came on a large scale, the people in Acropolis No. 1 abandoned the city and fled because they were afraid, and the reason was simple, because at that time, the No. 7 gathering place had already been breached.

When the news came, everyone in Acropolis No. 1 was desperate, and it is conceivable that even the No. 7 gathering place was breached, how could a small Acropolis resist the army of mutants.

So they abandoned the city and fled.

However, this should be a good thing for Hong Yi and them, because in a real sense, the Acropolis was not damaged because there was no decent battle.

It was a relatively intact city. (To be continued......)
