Moreover, they seemed to have found a way to avoid the damage from the explosive crossbow bullets. Although Lou Feier's hand speed did not slow down and the number of explosive crossbow bullets shot out was increasing, the frequency of the prompt sound in Xu Xin's ears decreased instead.

The defense line of the plant's heart began to be slowly pushed forward.

Ninety meters, eighty meters, seventy meters...

"They are coming! What should we do?" Lou Feier said anxiously.

"Do what you have to do, and I'll take care of the rest."

Looking at the mutant creatures getting closer and closer, Xu Xin decided to go down and fight the intermediate mutant creatures on his own, which would also allow him to test his current fighting strength.

With the purple-level steel armor, it is difficult for ordinary mutant creatures to hurt him.

"Xu Xin, those intermediate mutant creatures are moving!" Lou Feier discovered the abnormality and immediately reported it to Xu Xin.

"...You keep attacking from up there." Xu Xin quickly reloaded his repeating crossbow, leaving her with a backpack full of explosive crossbows. "If you run out of ammunition, reload it yourself. Don't stop for a moment!"

“It’s the master!”

Xu Xin prepared to go down the tree house with Mimi and Yin Wang, who had been eager to go out and could hardly contain themselves.

Keke also wanted to follow, but was pressed against the windowsill by Xu Xin.

They were going down to fight, not to explore far. Taking Coco with them would be a burden, and it might get hurt, so they definitely couldn't take it with them.

"Hmm..." Coco knew that she couldn't help much, so she could only lie on the windowsill, feeling a little lost, staring blankly at the bloody battle below.

When Xu Xin came down from the tree house, the army of mutant creatures had advanced to about 60 meters, approaching his electric fence.

At the same time, he saw several intermediate mutant creatures mixed in with the mutant creatures, rushing towards this side rapidly.

If Xu Xin hadn't temporarily suppressed them, Silver King and Mimi would have already entered the herd and started slaughtering them. However, they couldn't be allowed to enter the herd, as they had to face these intermediate mutant creatures.

Moreover, it's time to try out the power of this purple-grade steel armor!

There are a total of five intermediate mutant beasts, all of which have now mixed in with the mutant creature group.

With the help of the map in his mind, Xu Xin was still able to find them accurately. After all, their appearance was very different from the low-level mutant creatures around them.

Three of them are snow leopards, each of which is about the same size as Mimi. Moreover, compared to Mimi, who remains slender even when she grows up, these snow leopards are all muscular.

One was a snow wolf. Compared to the other snow wolves, this one was much larger, about the same size as the Silver King and the ordinary wolves in the gray wolf pack. It should be the wolf king of this group of snow wolves.

The last one is a snow fox. It is not big in size. Although it is larger than an ordinary snow fox, it is about the same size as an ordinary snow wolf. However, the brightness of the red dot is indeed several times that of an ordinary snow wolf. It is a mid-level mutant creature.

Five intermediate mutant creatures mixed in with the herd, dodging the attacks of the vines and rushing towards the tree house at full speed!
