Cheng Nan glanced back and saw that Zhang Mei had already gone far enough, Cheng Nan quickly retreated, and after estimating an appropriate distance, Cheng Nan threw the explosives in his hand with a fierce throw.

The explosives flew in a parabolic line towards the big hole, and the giant rat saw that a strange thing suddenly sprang out of the hole and habitually bit it.

Seongnam sneered and fell to the ground.

"Boom!" I heard a loud bang behind me, and a wave of heat suddenly surged from behind me. The whole cave began to shake, and countless dirt fell from his head, and Seongnam was almost buried alive.

"Ahem! Cough! Seongnam laboriously pulled the dirt off his body and got out of the mound. Fortunately, the amount of explosives is not large, otherwise the whole hole may be collapsed, and then my group of people are probably not eaten by these monsters, and they will be buried alive.

Seongnam struggled to stand up, looked back and saw that the hole behind him had been sealed, and he breathed a sigh of relief. It's just that there are countless holes in this cave, but they are connected, and Chengnan knows that the giant python and the giant rat are not dead yet, so he doesn't dare to take it lightly, and shouts as he walks forward: "Officer Zhang, are you okay?" ”

"It's fine." With the voice of Chengnan, Zhang Mei poked her head out of another cave and said, only to see that her head and body were covered with mud and looked embarrassed, obviously she was also smashed by the mud.

Chengnan walked briskly and glanced at Ah Yi, who was weakly leaning against the entrance of the cave, and lifted him up and said, "Hurry up, this is not a place to stay for a long time." ”

"Yes." Zhang Mei glanced up at the collapsed cave entrance, and then followed Chengnan. And Han Xiao was one step ahead of Chengnan.

A group of people didn't know how long they walked, but they didn't encounter those pythons and rats again along the way.

"I'm afraid I'm running out of batteries for this lamp." Seongnam muttered to himself as he looked at the dimming lights above his head.

Just when Chengnan was talking to himself, Han Xiao in front of him suddenly stopped and wondered, "What's wrong?" Han Xiao didn't explain, but pointed in front of him and exclaimed, "Look below." ”

"Below?" Chengnan was stunned, walked up to take a look, and was stunned. I saw that there was a deep valley three feet in front of my feet, and the deep valley was about a thousand zhang wide, and what was even more amazing in the south of the city was that there was a dense forest under the deep valley.

The forest is endless, and there is no end in sight.

"This... This.. How deep is the tomb, there is an inner valley, even a forest? Seongnam was amazed inexplicably.

"This underground valley is very common, but this underground forest is rare, and it is indeed rare to see so many plants that do not need sunlight grow here." Han Xiao said.
