The giant anaconda only showed half of its head, but it already made Xu Xin feel cold all over.

Damn, this big guy finally came out!

Don't attack the tree house!

With his current defensive means, he can never be a match for the giant anaconda in the center of the lake!

"Hmm..." Coco's two little paws were clinging to the window, with half of her head exposed. She secretly looked at the giant anaconda in the center of the lake, then she retracted her head in fright. However, she couldn't help but stick her head out to look again, and then retracted it again.

Silver King and Mimi also noticed the giant anaconda outside the window.

Although they have returned, the killing genes in their bodies have been fully activated after just experiencing a resounding killing spree, and the blood patterns on their bodies have become much brighter.

The Silver King kept making low growls from his throat, and Mimi also looked furious. The two beasts were very hostile to the giant anaconda outside.

"Xu Xin! Xu Xin! The group of mutant beasts outside have already surrounded the tree house! They've surrounded it! Attack? Should we attack?"

Lou Feier's hand was already hovering above the control panel. As long as Xu Xin gave the order, she would immediately launch an attack.

She did not see the giant anaconda in the center of the lake because the control panel could only see the scene within a range of two hundred meters around the tree house at most, and the lake was more than two hundred meters away from the tree house.

"Don't attack! Observe the situation first!" Xu Xin stared into the giant anaconda's eyes, which were as dark as the abyss, and cold sweat broke out on his head.

Now, the attack method that can cause the greatest damage to the beast group is the explosive crossbow in the repeating crossbow.

But the noise caused by the exploding crossbow was too loud. If he continued to fire and made noise, he didn't know whether it would anger the giant anaconda.

The giant anaconda in the center of the lake kept staring in the direction of his tree house.

Unlike the previous two times when half of its body emerged from the lake, this time it only exposed half of its head. It did not continue to emerge from the water, but maintained this state.

Xu Xin noticed something different.

He didn't know if it was an illusion, but he always felt that the half-protruding head was a little bigger than before.

...The giant anaconda in the center of the lake has become stronger?

"Are you really not going to attack? Those beasts are really going to pounce on us!" Lou Feier was a little anxious, her hand was about to touch the control panel.

"No need." Xu Xin said firmly, "Put your hands down!"

"I... okay..." Lou Feier put down her hands and watched the wild beasts around her getting closer and closer, then stepping over the snow and into the range of a hundred meters from the tree house.

Then, something happened that made her eyes widen.

The ground suddenly cracked, and countless vines emerged from the ground, easily piercing the first batch of low-level mutant creatures that stepped into the range of 100 meters, and pierced them straight into the sky!

"Vines..." Lou Feier muttered to herself, "Are they attacking mutant creatures?"

She didn't know about the plant heart because Xu Xin had never told her about it, and in District 187, only their boss Zhang Daoguang had come into contact with the plant heart.

Before she could react to what was happening, suddenly, a strange scream sounded from the jungle, and then all the beasts rioted instantly and rushed towards Xu Xin's tree house!

Xu Xin captured the strange sound perfectly, and his expression changed.

It's not a scream, it's... a whistle!

Someone is blowing a whistle! Use the whistle to control these mutant creatures to attack!

Was it the man he had just seen?

Xu Xin thought of the mutant human in his bracelet, but he didn't have time to interrogate him now. He could only wait until the attack was over.

Seeing so many creatures collectively attacking, Lou Feier subconsciously controlled the control panel to attack.

Xu Xin grabbed the back of her collar and pulled her away from the control panel.

"I said not to attack, don't you understand?" Xu Xin's voice turned slightly colder.

"But...but..." If we don't attack now, it will be too late when they come over...

Lou Fei'er felt a little aggrieved. She had clearly done this for the safety of the tree house. Since they were within range, why didn't they shoot in advance? Wouldn't it be too late when they got closer?

However, she had a serious psychological trauma due to the angry Xu Xin, so she did not dare to retort and could only lower her head.

"Go to the window and take a look yourself, then you'll know why I don't use the explosive crossbow to attack." Xu Xin's tone softened, which made Lou Feier breathe a sigh of relief. She ran to the window as if escaping and looked out.

Then she was so frightened by the half of the huge head in the middle of the lake that she covered her mouth: "What kind of monster is that? This... only the head is this big, its body..."

Xu Xin did not answer. He was always paying attention to the battle situation outside.

This group of mutated creatures is completely different from the fragile mutated ants that only knew how to attack tree houses. They are extremely aggressive!

Except for the first batch of mutant creatures who were easily killed by the vines controlled by the plant heart without knowing it, the mutant creatures that stepped into the range of 100 meters later were even able to fight against these vines!

Among the mutant creatures that attacked the tree house this time, there were three types at most.

Snow wolf, snow fox and snow leopard.

Xu Xin saw a snow wolf bite off a vine directly, then turned sideways to avoid the attack of another vine!

He saw a snow fox jumping nimbly between the vines, and the vines could not attack it.

Most of those snow leopards are intermediate mutant creatures. Although the brightness of the red dots cannot reach the brightness of huge mutant species in the tribe like Mimi Silver King, it is much higher than that of low-level mutant creatures.
