The entrance to the cave is dozens of meters high, which is enough to easily accommodate a large aircraft.

The downward steps are also extremely wide, one step is three meters wide.

It looks like this entrance is prepared for a giant over twenty meters.

Moreover, the cave appeared in front of everyone without any warning. This scene was quite shocking.

Even Wang Hongen, who had been prepared, was stunned, but his eyes soon showed ecstasy.

He couldn't wait to say, "This must be a ruin of ancient civilization. Let's go in and take a look."

Xu Yin hesitated: "I don't know if there is any danger inside, it's too unsafe to go in."

"First use small drones to detect the environment."

Wang Hongen prepared very well. He took out several palm-sized biplane drones to detect and scan the internal environment of the underground passage.

The drone is very fast, and all images and data can be transmitted back in real time. There are also artificial intelligence programs, which are completely automatic.

"The temperature is 24 degrees, the air content is normal, the humidity is normal, no harmful substances are found to the human body, and no abnormal energy radiation..."

All data scanned by drones is very suitable for human survival.

On the virtual light screen, you can clearly see the images taken by the drone.

The underground passage is more than ten kilometers long, and the entire passage is very flat and clean, without any danger.

At the end of the passage is a grand palace with a strange style. There is nothing inside, only a high platform in the middle.

Xu Yin also breathed a sigh of relief. The situation inside this ruin is very simple and there is no danger.

She was excited when she turned around, and any ancient ruins had important value.

Just this discovery is enough to publish dozens of papers.

A group of students didn't think so much, they were all extremely excited. The underground palace in front of them was completely beyond their imagination.

Young people are always full of strong curiosity.

Even Yun Qingshang looked inquiry.

Wang Hongen was very satisfied with everyone's reaction. He controlled the excitement in his heart and said in a deep voice: "There is no danger, let's go in and take a look."

With Wang Hongen's words, the impatient student rushed into the cave first.

Gao Xuan followed Wang Hongen with a smile, keeping a suitable distance.

He didn't know where there was danger inside. Anyway, he was following Wang Hongen, and it was easy to deal with if there was danger.

Yun Qingshang naturally had to follow Gao Xuan immediately.

Wei Zhenzhen also wanted to rush in to watch the fun, but she was more interested in Gao Xuan.

Compared to the mysterious underground palace, the extremely handsome brother Gao Xuan is more attractive.

Wei Zhenzhen was embarrassed to follow Gao Xuan alone, so she pulled Xu Yin together.

Xu Yin was particularly interested in the underground palace, but she was too urgent to show off.

Anyway, the underground palace can't escape here, so she doesn't need to worry.

Wang Hongen was very silent and didn't say anything along the way. His eyes shone, and he didn't know what to think about anymore.

Gao Xuan was very curious, what exactly Wang Hongen wanted to do?

The palace is empty, and the dragon's eyes are obviously not here.

Gao Xuan really wanted to snatch Wang Hongen's things, but he knew nothing about this thing, so he might not be able to use it even if he snatched it.

Strange things are all strange things and cannot be used to speculate with common sense.

Just like the God-Slaying Sword, if you don’t know the taboos of the God-Slaying Sword, you can’t control it.

Gao Xuan decided to wait.

No matter how scheming Wang Hongen was, he would never have expected anyone to wait for him here in advance.

As the oriole hiding behind, Gao Xuan doesn’t have to worry.

Wang Hongen and his friends walked for half an hour on the underground passage of more than ten kilometers.

When they arrived, the students had arrived long ago. They placed lights everywhere to shine brightly on the main hall.

The main hall is built with huge stones, and the whole style is simple, primitive and grand.

The dome of the hall is two hundred meters high, and it looks particularly small when people stand inside. The stone platform in the center of the hall is carved from a complete huge stone.

There are many images carved around the stone platform, and the lines of the image are simple and rough. But you can see that the combat situation is drawn.

A group of giants of that kind of weapon fighting monsters of all shapes, and in the end they all won the victory.

Xu Yin was particularly interested in these images. He recorded the picture while holding the smart watch, and lowered his head to study it carefully.

Wang Hongen circled around the stone platform for a half circle and came to the place with his back facing Xu Yin. He pressed the dragon teeth key in his hand on the platform and quickly recited several strangely pronounced mantras in his mouth.

He has been studying the Dragon Teeth Key for almost twenty years and has been very thorough.

This simple mantra is actually used to activate the altar.

That's right, this platform is actually a platform used by the ancient wisdom dragon clan to sacrifice prisoners of war.

If you want to get the treasures left by the dragon clan, you must first sacrifice flesh and blood, especially the pure young and young girls.

Wang Hongen insisted on leading the team in because he was attracted by these young students.

After the Dragon Tooth Key resonated with the altar, the huge altar quickly sank.

The whole process was filled with huge rocks rumbling, and the entire hall was trembling.

The sudden change also scared everyone.

A group of students looked panicked and didn't know how to deal with it.

Xu Yin was also shocked. If the palace collapsed, they would never have a chance to survive.

The underground passage is more than ten kilometers long, and it is too late to run now.

Fortunately, the rumbling shock stopped quickly, the platform disappeared, and the original place turned into a huge deep pit. It was visually estimated that it was dozens of meters deep.

A group of people looked into the deep pit, wanting to see what was going on inside.

Wang Hongen quietly took out a piece of Dragon Soul Vine from his pocket, lit it with a lighter and threw it on the ground.

The Dragon Soul Vine exudes a spicy aroma, which is a bit like fried chili peppers, and the taste is extremely exciting.

Because the air in the hall was clean, everyone had already taken off the filter mask.

The sudden spicy aroma caused a group of people to cough violently.

Gao Xuan saw it clearly from the side that it was Wang Hongen who was striking.

Xu Yin also saw it, and she asked in surprise: "Ahem, Professor Wang, what are you doing?"

"This is the dogwood that exorcized evil spirits and prayed for blessings in ancient times. When I saw this kind of ritual in the record, I took it out and tried it."

Wang Hongen answered casually, very calm and composed.

Xu Yin didn't think too much, but she felt that Wang Hongen did this without saying anything, which was a bit rough.

Gao Xuan felt that it was not good. The six-winged cicada in his sea of ​​consciousness had already begun to roar, reminding him that a huge danger was about to come.

Gao Xuan had time to leave now, but he was unwilling to leave just like that.

He winked at Yun Qingshang: "Catch him."

Yun Qingshang understood it and immediately urged his power to rush towards Wang Hongen.

With the blessing of Crimson Heart, Yun Qingshang is sure to capture Wang Hongen within three moves. If you want to kill Wang Hongen, one move is enough.

Although Wang Hongen is a level five source power, he obviously lacks combat experience.

Yun Qingshang was extremely fast, and his figure flashed and rushed to Wang Hongen.

Wang Hongen was shocked. Yun Qingshang was not only fast, but also had the momentum to penetrate everything with a simple palm knife.

Especially Yun Qingshang's body was full of power, which was thick and pure, and was actually two points stronger than him.

If it weren't for seeing it with your own eyes, Wang Hongen would never believe that Yun Qingshang was so powerful at such a young age. He had little combat experience and couldn't help but feel a little panicked when facing Yun Qingshang's fierce attack.

The people around were also shocked, and I wonder why Yun Qingshang attacked Wang Hongen.

Xu Yin was still stopping loudly: "Stop!"

Yun Qingshang didn't care what Xu Yin called, she only listened to Gao Xuan.

After all, Wang Hongen was a person who did big things. Instead, he calmed down at a critical moment. He knew that he could not retreat anymore, so he calmed down and put his cross-legged stent.

He has practiced boxing for many years, and this defensive boxing stance has been perfect. Facing Yun Qingshang's palm knife, he naturally used various changes in the cross boxing stance.

Wang Hongen found the feeling and his boxing skills became more calm and sophisticated.

Yun Qingshang was also a little surprised. This would lead to a situation of fighting, and it would be difficult to defeat Wang Hongen in a short time.

She didn't care about hiding her martial arts anymore. The straight-stinging palm knife suddenly turned like a spiritual snake, passing through the gap between Wang Hongen's boxing posture.
