Reborn in the end of the world, I scavenged in the empty city and bought for free

"Wait, don't go out yet!" Yan Fan pulled Xu Xuesong, who was walking in front. The main reason was that Xu Xuesong was almost at the door, and was shocked when Yan Fan pulled him back.

Cai Min immediately raised her arm, which had been hanging down, grabbed the gun, but she didn't know where to aim the gun, so she looked at Gu Tongwan. She instinctively felt that Gu Tongwan, who had been silent, might know something.

Gu Tongwan squinted his eyes and looked towards the door, then squatted down gently to comfort Aoao and Tutu who were always anxious.

At this time, the two dogs' hair stood on end, and there was a faint blue electric current lingering around them. The mental pressure on their bodies would affect the psychics next to them. For example, Xu Xuesong immediately felt a strong sense of oppression, but because Gu Tongwan was changing, he did not speak. He just quietly moved in another direction, at least three or four meters away, before he felt a little relieved.

Gu Tongwan gently soothed Ao'ao's neck with one hand, and patted Tuotu's head with the other hand. It took about two or three minutes to gradually calm the wolfhound down, and the black and white hair instantly drooped back to its original shape.

Liao Yunyun and Xiaoli also noticed something was wrong, but neither of them said anything, just stared at Gu Tongwan nervously.

Although Lan Cen's supernatural energy was low, he couldn't help but shiver when he looked towards the east.

"What's wrong? What happened?" Seeing that no one spoke, Xiaoli couldn't help but ask nervously.

"Something is coming from the east, and it's a very ferocious thing with a strong aura of supernatural power." Xiaoli took a deep breath before telling the truth.

Yan Fan clenched his fists, and then said: "It's not coming for us, it should be coming for the entire camp. Judging from the aura of supernatural power, it is at least above S level."

Xu Xuesong suddenly thought of something, so he asked in surprise: "Could it be that something came in from the high-voltage power grid that was broken before?"

The direction to the east happens to be the location of the high-voltage power grid that had been destroyed in the camp.

"S-class? Could it be a mutant beast?" A layer of fear covered Cai Min's face. Although she had never seen an S-class mutant beast, she had seen a B-class mutant lizard tear several people to death in an instant. Moreover, when Cai Xing was out on a guild mission before, he had survived the hunt of an A-class mutant rat king. That experience made Cai Xing recuperate at home for at least half a month. In the end, it was up to him to adjust his mentality and get out of this nightmare experience.

"If there really is an S-class mutant beast that breaks into the camp, then the other hunter guild members will not sit idly by and wait for death. We can't go anywhere now, so let's go back to our room first."

Gu Tongwan turned around and spoke to everyone, and then instructed Yan Fan to set up a new ice wall in the area outside the entire Cai family's yard.

Because he was worried that Yan Fan's special energy would be consumed too quickly, he handed over the only remaining bottle of nutrient solution.

"This is what Yan Xi gave me before he left. He said that ordinary people can also replenish their physical strength, but I don't need this at the moment. I'm not a superpower. It would be a waste for me to drink this, but it would be more useful for you."

Yan Fan shook his head and said, "Sister Wanwan, that's what the boss gave you. You should keep it. He told me to protect you no matter what."

"That's why you need to drink it. You must set up the ice wall in a short time. The nutrient solution can speed up the operation of supernatural energy."

Yan Fan hesitated for a moment, but finally nodded, took the nutrient solution and drank it in one gulp.

The nutrient solution that Chen Yanxi gave was the best medicine developed by the research institute. As soon as Yan Fan drank it, he felt a hot current rushing through his body, followed by a cool feeling spreading throughout his limbs. The aura of supernatural powers on his body was indeed much stronger than a few minutes ago.
