"Hide away!" Wu Dao dodged to the side, and the three women immediately stayed away from the sea of ​​flowers and held their breath.

"Puff puff puff." The big bug raised his head and kept spraying venom at the four people. Large areas of green plants withered, and thick smoke separated the insects from the four people. Although people could not see the insects, the insects could accurately aim at the four people.

"Puff", a stream of venom fell behind the four people and almost splashed on Wu Dao.

"Stay away!" He reminded the three girls again.

The three women turned around and ran to the left. Even though the situation was so jeopardized, the formation was not messed up. Yun Xing was still at the forefront.

The worm that sprayed venom three times in a row was lying on the ground and stopped moving, and seemed to be a circle smaller than before.

"Hu", a heat wave hits the face, the river surface is filled with hot air, the hot magma enters the water and the surface of the water turns black, and it moves along the river channel.

"Road along the river!" Yun Xing immediately turned around and ran quickly.

Zhang Qi and Tang Yaya immediately changed positions and ran to her left, while Wu Dao followed behind the three of them.

There was poisonous gas on one side and hot gas. Four people ran in the middle, fortunately the wind direction did not change at this time, and once the poisonous gas was blown over, it would probably be difficult to escape.

The heat and poisonous gas gradually decreased, and the three girls were so tired that they were sweating profusely.

Yun Xing gasped and slowed down: "I can't run a little!"

Zhang Qi swallowed his saliva and asked breathlessly: "How far is it?" Even she couldn't stand it when she ran quickly for six or seven kilometers.

"It's coming soon!" Yun Xing looked at the sparse tree in front of him.

Tang Yaya turned her head and looked behind her: "I'm really curious about killing the cat. Can you not do such a thing in the future?"

Wu Dao looked at her with a smile: "You two want to see it, otherwise you can dig it out!"

"I was wrong, apologize to you and Yun Xing!" She said and looked at Yun Xing.

Zhang Qi glared at her dissatisfiedly: "Why did you apologize to them or not to me?"

She rolled her eyes to Zhang Qi: "The four of us belong to you. If you didn't say you wanted to see what the root looks like, Yunxing could dig it? You would be embarrassed to ask me to apologize, do you want a dart? I'll tie you into a hedgehog!"

Yun Xing glanced at Zhang Qi with gloating and looked at Tang Yaya: "She wants it, give it to her quickly!"

Tang Yaya shook her head: "Forget it!"

Zhang Qi raised his hand and grabbed her arm and said with a smile: "I knew you wouldn't bear to stab me!"

She immediately hid aside: "You are thinking too much, not that I can't bear to let go, but that you are too thick-skinned and don't want to waste darts!"

"Hahaha..." Yun Xing and Wu Dao laughed happily.

Zhang Qi's face suddenly turned into a pig's liver. He clenched his fists and stared at Tang Yaya with gritted teeth: "Do you believe it or not, I will beat you to death with one punch?"

"Finish!" Tang Yaya nodded.

Zhang Qi raised his fist and put it down again, so angry that she could only glar at Tang Yaya fiercely: "You are cruel!"

Yun Xing covered his stomach and pointed to a thick tree on the right: "The smoke I saw at that time was next to that tree!"

"It's almost a kilometer away from here!" Wu Dao said, looking up at the sky: "Let's take a few steps, it won't be dark when you get to the place!"

Zhang Qi glared at him: "You are like urging your life, always urging us. Can we be as fast as you?"

He clenched his fists and said, "Believe it or not, I'll beat you up?"

Zhang Qi gave him a thumbs up in disappointment: "You are amazing, you are all amazing!"

The four people soon came to the tree that Yun Xing pointed at, but there was no ashes here, so Yun Xing led the three of them to continue walking forward.

"Look, it's that fire!" She pointed to the pile of ashes in front, and accelerated her pace.

"It's true!" Zhang Qi stared at the ashes in surprise.

Wu Dao walked up to the two of them, looked down at the ground: "Let's see if there are any footprints on the ground first."

Yun Xing and the other two also looked at the ground and scattered.

"There is here!" Zhang Qi pointed to the ground and looked at the three of them.

Wu Dao and the other two immediately ran to her, and a footprint with only three toes appeared in front of the three.

Yun Xing raised his foot and stepped on a shoe print next to the footprint. After comparing the two, he said, "It shouldn't be human, right? First of all, the number of toes is wrong, and secondly, there is not even a trace in the soles of the feet."

Zhang Qi looked at her and said, "First point, leaving toes on the ground means that you are not wearing shoes; second point, many reasons can cause no traces in the soles of the feet, such as a gust of wind, or something tied to the feet. Third point, in this bad situation, is it normal to break two toes? Is it also normal to tie two toes more when tying your feet?"

Wu Dao gave her a thumbs up: "The reasoning is reasonable and well-founded!" Yun Xing looked at the two of them: "Is this a human footprint?"

Zhang Qi shook his head: "Not necessarily, it may also be primates, such as monkeys, orangutans and baboons."

Yun Xing turned around and pointed at the fire: "Do you think monkeys will ignite now? The earliest Shanding Cave was 18,000 years old, and this place was the Cretaceous period at the latest. According to the era we live in, there are more than 100 million."

"Then do you have to consider prehistoric civilizations? Maybe there were already savages in this era. In fact, they were the earliest civilizations, but they disappeared later with the dinosaurs."

Yun Xing gave her a thumbs up: "Sister, you are amazing, you actually make me speechless!"

Tang Yaya looked at the two women: "If there is really a prehistoric civilization, wouldn't there be tribes or cities in this era?" She looked down at the footprints: "This footprint was left by the savages who came out of the tribe to hunt. Does this make sense?"

Wu Dao pointed to the side and looked at the three girls with a smile: "Is the shoe print next to him more certain about the prehistoric civilization?"

The three girls looked in the direction of his fingers at the same time, and a clear shoe print entered their eyes clearly, and the patterns on the shoe prints were extremely clear.

Zhang Qi stepped on the shoe prints next to the shoe prints, raised his foot and stared at the two shoe prints in surprise: "It's as big as my shoes!"

Yun Xing pushed Zhang Qi and Wu Dao away from both sides: "Hurry up, see where the shoe prints are going!"

The four of them walked forward along the shoe prints and soon came to the river because it was very difficult to find the shoe prints because they were all stones.

Wu Dao turned around and looked at the green plants and walked over, looked carefully and walked back to the river: "There are no signs of trampling there, you can be sure that you walked from here."

"Hey!" Zhang Qi thrust his fist in annoyance: "I wouldn't catch fish if I had known it. Maybe I could still meet them when I came here."

Tang Yaya looked at the three of them: "We didn't meet them here. Could it be that they didn't walk from here, but followed the river down the river?"

Wu Dao nodded: "It's very possible!"

Zhang Qi looked up at the sun that was about to set: "Can you still look for it?"

Wu Dao hesitated and shook his head: "Look for it tomorrow!"
