The fight lasted for a day and a night, and Zhu Yuan slashed and killed for a day and a night. For a day and a night, Zhu Yuan was still standing in his original position, but what he stepped on was no longer the land, but the corpses of countless mutants.

The day and night of fighting made the dense mutant population thin, and Zhu Yuan even saw the intelligent mutant hiding at the back of the mutant population.

When the other party saw Zhu Yuan looking at it, Zhu Yuan obviously felt its panic, and then Zhu Yuan saw that the wisdom mutant retreated with the remaining mutant population.

Zhu Yuan put away the green scale knife and re-received the rule black box into the bag.

Zhu Yuan was able to hold on for a day and a night, not because of how strong his physical strength was, in fact, his physical strength had been exhausted, and he relied on the wood system vitality rules to continuously provide vitality to his body.

So after the power of the rules receded, Zhu Yuan felt exhausted, as if his body had been hollowed out.

"Master, hurry up and take a rest." Behind Zhu Yuan, Guan Cheng's eyes were full of stars, and he said adoringly.

"Okay."

Zhu Yuan nodded, found a quiet place to close his eyes and recuperate after the fortifications, and fell asleep for a while, until the sky was dark again, Zhu Yuan woke up leisurely.

Zhu Yuan, who opened his eyes, immediately glanced around and found that except for the necessary patrol and vigilance soldiers, the other soldiers were like him, holding their weapons and closing their eyes to rest.

Zhu Yuan stood up, walked to the fortifications, and raised his eyes to look out of the passage, where the corpse of the mutant who had occupied the entire passage had been cleared out.

The corpses of the mutants that were cleaned up were randomly piled up into several corpses, but if you didn't look closely, you thought that there had been a terrible massacre here.

In fact, the massacre is similar, it's just a massacre of mutants by humans, as for the piles of corpses, I heard those patrolling soldiers say that it is to deter mutants, and I don't know if it's useful or not.

The night was silent, and after spending it in peace, the wisdom mutant seemed to leave with the mutant population.

The renovation of Qingdu City was also extremely smooth, and on the third day, the transformation of Qingdu City was finally completed.

The ruins of this city, although there is a lack of food, there is no shortage of various materials, so the transformation of Qingdu City can be so smooth.

When the sun rose on the fourth day, Qingdu City drove out of Ruined City, but he didn't expect that the wisdom mutant who thought he was retreating had already made an ambush in front of Qingdu City, and the unprepared Qingdu City plunged into the ambush.

"All warriors, defend your homeland to the death." Helian Kangan climbed to the top of the city and shouted.

Qingdu City was caught off guard by this ambush, who would have thought that the wisdom mutant would hide in a valley with the mutant population and wait for him!

When Qingdu City entered the valley, countless mutants poured out from all directions, breaking through the fire blockade in an instant and landing on Qingdu City.

Qingdu City is in crisis, men, women and children, all the alien warriors who have been transformed have all gone out to fight, and they are fighting hard against the city wall.

Faced with this situation, although Zhu Yuan had the heart, he was powerless to help Qingdu City. There are about twenty cities in Qingdu City, and although Zhu Yuan is not afraid of these mutants, he only has one person who is weak.

High up in the valley, the wisdom mutant looked down, and the corners of his mouth showed a humane smile. It let out a few excited ahs, and walked towards Qingdu City with the armed mutant by Gongwei's side.

At this time, the walls of Qingdu City have been breached, and people are hiding inside the city, struggling to resist the abnormal population attacking outside the city.

"Helian, let me bring someone over." Luo Mengxiang shouted hoarsely.

"No, city lord, you can't go over, now the connecting passages between the various cities have been occupied by mutants, and if you go, you will go and there will be no return." Helian Kangan stopped Luo Mengxiang and said eagerly.

"But I can't look at Qingdu City, it's ruined like this." Luo Mengxiang had tears in her eyes.

Helian Kangan shook his head, all they could do was to defend the main city.

"Mr. Zhu." Luo Mengxiang looked at Zhu Yuan for help.

Zhu Yuan shook his head, he couldn't help it. When he leaves, the main city will be in danger, and the people around the main city are armed mutants.

But immediately Zhu Yuan changed his mind, because he saw the approaching wisdom mutant.

"City Lord Luo, do you dare to be a bait to bring people to reinforce the city bodies and attract the attention of that wisdom mutant." Zhu Yuan said.

"Why don't you dare." Luo Mengxiang said that it was her duty as the city lord to rescue the people.

"Okay, responsible. Helian, take your most elite team and follow City Lord Luo. Zhu Yuanyou said to Helian Kang'an.

Helian Kangan didn't trust Zhu Yuan as much as Luo Mengxiang, he asked:

"I'm sure you can defend the main city, but what about the city's safety? You don't care about the safety of the city lord, but I am responsible for the safety of the city lord. ”

"Can't you protect your lord?" Zhu Yuan said excitedly.

Helian Kangan struggled inwardly, and finally gritted his teeth and said, "Yes, I can't protect the safety of the city lord in this situation. ”

Zhu Yuan looked at Helian Kangan in surprise, he didn't expect that in such a dangerous situation, Helian Kangan would not eat his radical general, so Zhu Yuan could only say helplessly:

"I asked you to do this so that you might show weakness. You don't really come to the rescue of the cities, all you need is to attract the wisdom mutant. As long as I can lure that wisdom mutant to Qingdu City, I can be sure to kill that wisdom mutant in an instant. ”

"Really?" Helian asked suspiciously.

"Really. You don't believe me? Zhu Yuan replied.

Luo Mengxiang answered: "Okay, just do what Mr. Zhu said, I believe Mr. Zhu." ”

"But ......"

Helian Kang'an also wanted to ask Zhu Yuan, how could he guarantee that as long as that wisdom mutant appeared under Qingdu City, Zhu Yuan would be able to kill it, you must know that Qingdu City is a long type, and the city body behind it is a long distance from the main city body.

But Luo Mengxiang didn't give Helian Kangan a chance to ask, because she had already led people out of the main city.

"City Lord!" Helian Kangan only had time to shout, and hurriedly led people out.

Zhu Yuan looked at Luo Mengxiang and Helian Kang'an who had left, his right hand kept waving the green scale knife, but his left hand was quietly placed on the surface of the rule black box.

Sure enough, Luo Mengxiang and Helian Kang'an led people to attack, attracting the attention of the wisdom mutant.

This can't help but be inattentive, Luo Mengxiang and Helian Kang'an are all Nengjing warriors, where can ordinary mutants stop them.

Most of the armed mutants are concentrated around the main city, and they are held back by Zhu Yuan. The remaining small part followed the wisdom mutants, and if they wanted to stop Luo Mengxiang and them, they could only rely on the remaining armed mutants.

Thinking like this, the wisdom mutant glanced at Zhu Yuan who was guarding the main city body in fear, and after Luo Mengxiang and them left the main city body at a sufficient distance, the wisdom mutant took the remaining armed mutants and pounced on Luo Mengxiang and the others.
