Before long, what Wu Chengyue and Xiao Licheng worried about really happened.

About half a month after Xie Dong and his men destroyed the three-thousand-men troop from Sky Fire Base, five seven-meters-wide holes appeared near the area that Yun Meng's regiment was stationed in after dusk, before it was completely dark.

Yun Meng and her zombie soldiers instantly sensed a strong earthy smell from that area coming from a few different directions. So, she immediately brought a few zombie kings and queens to that area and found more than one hole.

No sound could be heard from those holes as countless underground creatures that were at the size of mature gorillas silently crawled out of the ground. Hundreds of them were already standing near the holes.

Soon, the zombie kings and queens who were sent to the other underground cave entrances returned. A large number of underground creatures were found near every entrance. The five entrances were in a straight line; the one nearest to All Beings Base was at least thirty miles away from the furthest entrance, but was only about twenty miles away from the base.

Obviously, those creatures were targeting the base.

"Go and inform Chief about this ASAP! Get ready for war! Earth power! Find a way to block those holes right now!" Yun Meng returned to the base camp and immediately gave her orders. She first sent a group of zombie soldiers to each entrance, then started gathering the surrounding zombies to stop those underground creatures from spreading.

"Roar…" A muffled roar was heard from a distance away, and Yun Meng's heart leaped.

In All Beings Base, Lin Qiao, Yuan Tianxing, Lin Feng, Qiu Lili, and the other level-seven beings all paused and turned to where the underground cave was located. Even Wu Chengyue, Zou Shihui, and Xiao Yunlong, who were in Sea City Base, had also sensed something. The distance between the cave and Sea City Base was large, so only Wu Chengyue, who was relatively stronger, sensed that familiar vibe clearly.

He thought for a moment, then suddenly had his expression changed.

At that moment, the underground creatures, which were surrounded by zombies, started turning red. Within a blink, they all switched to the crazy mode and launched indiscriminate attacks against the zombies.

The area one mile around each entrance instantly became the battlefield of the beasts and the zombies.

"Roarrrr!"

"Roarrrr!"

Human beings couldn't understand their raging roars.

"Damn! I was wondering why weren't they making any move! They were planning this!" Yun Meng showed up near the entrance that was the nearest from All Beings Base and cursed through clenched teeth. Then, she stormed into the battlefield while swinging both arms and easily cutting off the heads of a few low-leveled underground gorillas.

No one could have thought that those underground creatures would launch a massive attack, without showing any sign before it. They created five new exits of the underground cave, but didn't cause any noise!

"Roar!" A five or six meters tall underground gorilla rushed out at Yun Meng like a buffalo and wielded his claws. Its body glowed with a red light and its sharp teeth shone brightly in the darkness.

"Bang!" The crazy underground creature had both its speed and strength boosted to a higher level. As a result, its claw landed on Yun Meng's body and sent her flying away!

"Eh… Pah!" Yun Meng felt pressure from her chest, and then a salty stream of liquid gushed out of her mouth. She coughed out some thick and black zombie blood as she bumped into a house. Soon, she rushed back out, leaving a hole on the wall.

A small part of those underground creatures were left to guard the entrances. Yun Meng ordered some earth-powered zombies to seal those holes, yet those creatures attacked them fiercely. The earth-powered zombies didn't approach them, but still got spotted.

A ten-meters tall underground gorilla crawled out of the hole near Yun Meng, then stood there motionlessly as it faced All Beings Base, sniffing at that area.

Behind him, more and more underground gorillas of different sizes crawled out of the hole. Soon, no more underground gorillas came out of the rest four holes. Each hole was surrounded by four or five hundred of underground gorillas, including two level-seven ones. Those level-seven underground gorillas violently attacked the level five or six zombies who were under Yun Meng's command.

Yun Meng didn't have many zombie kings and queens under her command. Old Guo, Eight, Three, Xia Ri, and Nan Jin each led ten zombies leaders and launched attacks.

Once that gigantic gorilla released its vibe, Lin Qiao, who was in All Beings Base, instantly detected danger. She quickly changed into a combat suit, picked up her son, and thrust him into Shen Yujen's arms.

"Send him to Lin Hao's place!" She said to Shen Yujen, then turned to her son, "Son, go and stay with your uncle. Mama needs to leave the base for a while."

"Go." Teng gave her a glance and then calmly waved an arm. Teng was almost a month old, no longer soft and weak like he was before. He was still tiny, but he was strong!

Lin Qiao left her office and sent Duan Juan to deliver her urgent order to Yuan Tianxing and Xie Dong, then drove out of the base in a haste.

At that moment, more underground gorillas had been coming out of the hole that was the closet to All Beings Base. While Yun Meng was fighting against a crazy level-seven underground gorilla, a large crowd of underground gorillas had already shown up near the hole. Apart from the two level-seven ones who were fighting Yun Meng and Xia Ri, five more were quietly standing behind that ten-meters-tall one.

That level-eight underground gorilla seemed to be a leader.

"Roar!" Abruptly, the gorilla leader seemed to have sensed something. It bared its teeth and raised his head to utter a roar, giving out some kind of order. After that, it lowered its body and sprung up, leaping toward All Beings Base.

Once it moved, all the other underground creatures, which were standing there quietly, all followed behind it. Their bodies glowed with a red light, even illuminating the entire area.

"This is bad!" Yun Meng shouted out loud without thinking. She dodged the level-seven gorilla's claw, then saw the gigantic creature lead over a thousand underground creatures toward All Being Base.

She wished those creatures wouldn't go all the way to All Beings Base that was located in twenty or thirty miles away. She hoped they would worry about getting lost.

If those creatures really broke into the base, a disaster would descend upon the base.

The giant crowd of underground creatures might have given out an exceptionally strong vibe that made the rat group—which was on the other side of the base—draw back into their nest in a flurry, seemingly frightened.
