"Bang bang!"

Two deafening gunshots, the mermaid who was rushing to the halfway, was shocked, and a large piece of blood and flesh exploded from her body and sprayed on Bai Yu's face. Her body spasmed for a few times and fell down softly, sliding into the pool, and the water surface suddenly turned bright red. The mermaid who confronted them was also shot, and she let her hands back in a panic and tilted into the pool with a "por".

Zhao Tiange!

He climbed the vine and jumped out of the crack of the rock above, his nose and face were swollen, and he cursed:

"Damn it, I was not lucky enough to even lose my marksmanship. At my level, I should have shot one shot at one shot."

It turned out that he rolled down from the steep slope and crashed into the stone cliff and fell into a coma. After waking up, he groped in the dark for a long time. When he heard something was happening below, he tried to find the gap.

After discussing, I felt that the stone pool was unfathomable and did not rule out that there were more mermaids hidden in the water, but I gave up my plan to go to the other side and returned from the cracks of the rock to the upper level to find another way out.

"Although the slope is very steep, I have to try to return the same way. The cave is so scary." Zhao Tiange said in lingering fear.

Bai Yu pondered: "Ghost Fire is a hurdle that cannot be overcome..."

"What if it doesn't matter, avoid the ugly mermaid first." Lan Duo said.

Next, Bai Yu rode on Zhao Tiange's shoulder, groped inch by inch on the surface of the stone cliff above his head, and finally found the gap that fell, climbing the vines back to the upper level with great difficulty.

I rolled down very quickly just now, and then I calmed down and found that the stone slope was very steep, and the surface was smooth and there were no stones, trees, vines, etc. The blue duo relied on his light and flexible body and climbed less than twenty meters in one breath and then retreated.

"It's so damn funny!" Zhao Tiange cursed.

Bai Yu asked in a deep voice: "Do you see the space above clearly? How far is it?"

Lan Duo shook his head: "It's too dark, I can't see clearly."

"From the time and speed when we rolled down, it was at least fifty meters!" Zhao Tiange said.

Bai Yu was about to speak, and suddenly pushed Zhao Tiange hard. He heard a "huh" sound, and a large ball of dark things passed by his head!

"What the hell?" Zhao Tiange shouted.

Lan Duo quickly threw a ball of burning vines into the distance. Under the light of the fire, he saw a monster like an eagle standing on the towering stone. His whole body was pitch black and more than half a meter high. His feathers were like long arrows, sharp and sparse. His sharp teeth were stretched out on both sides of his lips, and his long and thin tongue licked them on his teeth. His blood-red eyes were staring, and his eyes were filled with cold hostility.

Lan Duo threw a ball closer, and saw two people standing behind it, one lying and one standing, motionless like a clay sculpture.

"Have Tiange seen this monster in the reserve?" Bai Yu asked quietly.

Zhao Tiange rarely showed fear on the ground: "The squid! It is called the squid! An extremely rare ancient creature, which usually grows and reproduces in graves. Its whole body is as hard as iron, its blood is highly toxic, and it is very aggressive. When a tiger, leopard, black bear sees it, it has to escape..."

Bai Yu stopped the conversation and asked, "How to deal with it?"

"The squid is the product of extreme cathodic cold, fearing fire..."

"Hurry up, each person will stab each!" Bai Yu ordered.

Lan Duo said: "There are no vines here..."

After saying five words, the wings suddenly opened its wings and pounced on Zhao Tiange. Zhao Tiange kept staring at it, quickly pulled out the soft baton from his waist and swung it hard, and flew it with the wings claws, making a tooth-inspiring sound.

The squid was caught and returned to its original place. Zhao Tiange and Bai Yu looked at the soft baton and their faces were pale. High-tech molecular composite plastic was actually caught in four small pits. If it were the head, even the brain would have flowed out.

"You can't fight head-on, retreat quickly!" Lan Duo also realized it very well and whispered, "Just retreat to a place with vines and everyone can hold a torch."

As if he understood what Lan Duo was saying, three horns suddenly spread their iron wings and rushed over at the same time. The finished font-shaped echelon just avoided the forefront Lan Duo.

Lan Duo waved the torch as tight as possible to protect Bai Yu and Zhao Tiange from retreating quickly. However, the turtle seemed spiritual, and the top one drew an arc and went backward to block their retreat to collect vines.

Zhao Tiange waved his soft baton to help, blocking their attacks as much as possible. In the dark, the soft baton "tuk tuk" was unknown what it was like.

With their all efforts, Bai Yu lit a flint from time to time to explore the way. Suddenly, he found a stone cave at the middle end of the stone cliff. A silver-white stone curtain hung outside the cave. A huge rock was covered with mountains and mountains below. The passage into the cave formed a "Z" shape and the entrance of the cave was only about one foot high, which could effectively prevent the pursuit of the turtle.

After the three of them struggled to penetrate into the cave one by one, the squid was still strikingly hitting the stone curtain outside, with its strength being astonishing.

"I feel like I've traveled to the primitive society," Lan Duo asked while collecting vines and tying torches, "All these monsters, Fenghuahua know about them?"

Zhao Tiange's face was solemn: "Forest** also understands it, but she doesn't have the same specificity as she can use her natural geographical advantages to set up a trap. I really underestimate her!"

"The retreat route was cut off layer by layer, as if there was no choice but to go deep into the cave's heart." Bai Yu said.

"Yes, let's take a look..."

Speaking of this, the three of them took out their cell phones that were covered in cracks at the same time and looked at them, but there was still no signal, so they could not even send out a rescue signal.

After walking along the cave for more than ten meters, a strong wind suddenly blew from the side, and the strong wind "punched" to blew out the torch in Zhao Tiange's hand.

After walking a few steps towards the wind source on the side, a straight and spacious corridor appeared in front of the torch. The stone walls on both sides of the corridor were covered with caves of all sizes. The sound of ghosts and wolves howling came from inside. Sometimes it was like the roar of wind in the desert, sometimes it was like an old woman sobbing alone, sometimes it was like a sharp whistle mixed with sonorous gongs and drums, and it was wrapped in a powerful airflow.

Bai Yu put on his clothes and took the lead to force his way forward. Zhao Tiange grabbed him and said loudly: "You can't be rash, the wind inside is so strong that it's beyond your imagination."

"Just walk close to the side, just be careful." Bai Yu said.

Zhao Tiange retreated to the back, collected a large handful of dried vines around and wrapped them into football-sized vines, put two small stones inside to increase the weight, put them in his hand and weighed them, walked to the entrance of the corridor and threw them inside.

When the vine bun flew over the corridor, it seemed to be pulled by huge force from all directions and fell apart in an instant. The vine bun seemed to be sucked into a crusher in the air. It was first broken into countless pieces, and then turned into dust before landing, disappearing without a trace. The two pieces of gravel wrapped inside were also sucked into the caves on both sides.

Bai Yu and Lan Duo were stunned and then they understood the reason why Zhao Tiange stopped him.

"I heard that there is this place in Lushan, but I didn't expect to see it with my own eyes today," Zhao Tiange asked, "Do you know the wind tunnel?"

"I learned it in middle school that a wind tunnel is a pipe-like experimental equipment that artificially generates and controls airflow to simulate the flow of gas around an aircraft or object, and can measure the effect of airflow on objects and observe physical phenomena. It is the most commonly used and effective tool for aerodynamic experiments. It is widely used in aerospace, transportation, construction, wind energy applications, etc. It is mainly composed of cave bodies, drive systems and measurement control systems," Bai Yu said in surprise, "This is in front of him? How is this possible? Wind tunnels are artificially formed experimental environments..."

Lan Duoyou said: "Lushan is a place that breaks the scope of cognition."

Bai Yu observed carefully and said, "If you enter the wind tunnel rashly, you may end up in pieces, right?"

Zhao Tiange said: "My head teacher at Forest** School was a special forces member before and participated in some top secret operations. According to his recollection, he and a comrade were ordered to go to a military base to participate in wind tunnel testing. The leader asked them to drive a truck full of instruments and cotton, jump out of the car when they drove to the wind tunnel entrance at the highest speed, and let the truck rush in with inertia. One is to collect various data, and the other is to observe whether the cotton is scattered randomly or follows certain rules. The head teacher first

The task was successfully completed. When it was the turn of that comrade-in-arms, it was an accident. For some reason, he couldn't pull the door handle when he was about to jump off the truck. Life was fleeting. In a blink of an eye, he drove into the wind tunnel with the truck... A truck full of snow-white cotton was dyed bright red, and stars were distributed on the four walls of the wind tunnel! As a special forces soldier, the head teacher had seen too many deaths and had also experienced the scene of comrade-in-arms lying beside him and dying in his arms, but the death of this comrade-in-arms was the most unforgettable!"

"We can only stay away from each other and go back and find another way out?" Lan Duo asked with a frown.

Bai Yu thought for a long time: "Not necessarily! If it is formed naturally, it must be affected by the strength of the wind outside the mountain. When the wind weakens, you can rush over."

Lan Duo shook his head and objected: "If the wind becomes stronger halfway through the journey... This idea is too risky and it's just a life-threatening thing! It's better to keep going, maybe there may be other channels."

Unexpectedly, Zhao Tiange also agreed with Bai Yu's idea: "There are steep slopes that cannot be crossed by ghost fire. I don't think we have a choice, so wait patiently, maybe a miracle will happen."

"We will be torn into pieces by the wind like your class teacher's comrades!" Lan Duo still objected.

Zhao Tiange said: "That's better than tearing it into pieces under the claws of the squid!"

"We don't have the ability to fight back in the wind tunnel. After all, worms are creatures, and they can always find their weaknesses..."

“We can’t experiment at the cost of our lives…”

While arguing, I suddenly heard something behind me. I turned around and raised the torch and couldn't help but feel creepy: three pisses actually crawled into the narrow gap!

"Stop quarrel now, just break through!"

Bai Yu decisively threw the torch at the turtle, and Zhao Tiange rushed into the wind tunnel as usual.
Chapter completed!
