Jiang Yan immediately chased after him, and when he chased it out, he only saw a black shadow flash away and enter another passage.

Entering the passage, Jiang Yan found that there was a third layer of space in the entire underground cave, and there were also artificially dug stone stairs in the passage he was in.

The black shadow moved extremely fast, passing through several narrow corners in a few flashes, and had entered the third layer of space at this moment.

With the brighter and brighter light, Jiang Yan knew that the outside was a cave space that communicated with the surface of the mountain.

Jiang Yan exerted force again under his feet, and with his induction, he had already rushed out in a few steps, and his body landed in the cave outside.

But just as his body flew out of the hole, several red dots flashed rapidly, and a roar suddenly exploded.

In fact, when he saw those red dots, he had already realized what the other party had left behind at the exit of the passage, so he subconsciously urged the Heart of the Galaxy to form an almost transparent particle shield on the surface of his body.

This particle shield is also a feature that he stumbled upon and has a good protective effect, but he has not experimented with it either. It's better to use it directly at this critical moment than nothing, right?

As a ball of fireball engulfed Jiang Yan, the shockwave swept towards his body with debris.

Obviously, these stone chips were slowly paused outside his body, and his dantian also stagnated suddenly, and his body flew out directly.

Luckily, just a few minor abrasions, apparently their own particle shield has consumed most of the shock.

At this moment, in the dark corner, there were people watching the scene that had just happened, and one of them had a look of surprise in his eyes, while the others looked very wooden.

The man made a gesture again, and a tall white man suddenly moved, and pounced directly towards Jiang Yan, furious like a beast.

Jiang Yan was obviously a little caught off guard, and while he was surprised, he also directly took the other party's punch.

The person who came didn't say a word, his eyes were full of woodenness and rage, but the attacks of his hands and feet were continuous, and the strength was extremely strong.

While fighting, Jiang Yan was compared with Liu Qing, who had fought with him, and according to his own calculations, Liu Qing couldn't last ten moves under the opponent's hands.

The two exchanged blows for dozens of rounds, Jiang Yan's arm was numb, the strength of the white man was too domineering, Jiang Yan admitted that his physical strength was far from the opponent of the other party.

But once the power of the Galactic Heart was activated, the situation on the battlefield suddenly reversed.

But the next scene also made Jiang Yan a little shocked, the power of the double dust that pierced through Yang in the past only shocked the other party.

Seeing that the big man who had broken an arm was still brute force, Jiang Yan also seemed a little anxious.

Directly launched the power of the falling star and pointed at the opponent's chest, and just as the opponent's figure was about to get closer, a dark golden streamer suddenly burst out from his fingertips.

The white man's figure suddenly froze, and then there was a muffled sound in his body, and his body collapsed directly.

Jiang Yan saw it clearly, until the other party's figure collapsed, there was no abnormality in this person's eyes.

Damn, doesn't it hurt?

Such a thought was only fleeting in a blink of an eye, and several figures actually came out of the darkness again in unison, heading towards Jiang Yan to surround and kill.

Just as they were fighting, in the darkness, a small-eyed white man was putting away the miniature probe in his hand, and his figure disappeared into the light of the cave in a flash.

The few people who besieged Jiang Yan were also fierce, and what made him feel strange was that the strength and combat skills of these people were exactly the same, which seemed very weird, which reminded him of the cyborg people studied by BT Country.

After a moment of fighting, Jiang Yan gradually verified his guess, these people's offensive and defensive methods were completely designed, and there was almost no pain, because he had already removed several arms from the other party.

One man's chest had long since been pierced by his dusty force, but the man continued to fight, and did not go limped until the blood was gone.

After verifying his guess, Jiang Yan was a little afraid, but fortunately, there were only three people who beat him in the group, if it was ten people and 100 people, or if it was an army of cyborgs? So what?

With such a thought, he himself felt scared, so he simply directly launched the power of the meteor to kill the other party in seconds.

Several people who besieged Jiang Yan had all been killed, but only one of them was still intact. Jiang Yan approached to investigate again, and sure enough, he found a chip substance in the back of the man's head.

This is a siliconous biochip, and if you don't see the almost transparent circuit in it, most people think it's just a sarcoma.

What surprised him even more was that the biochip existed alone, and no smaller energy supply device was found, and the chip had grown completely in the cortex.

This technology is really amazing.

Jiang Yan put away the biochip and found that the person who had fled before had long since disappeared. At this time, I was afraid that it would be in vain to chase it out, so I simply investigated it again in the cave.

This is a huge hall space, and the entrance to the outside world has been clearly seen, and the cave is full of quaint Chinese buildings, some signs of damage.

There is a stone gatehouse standing from the entrance of the cave, and there are three big characters written on the stone plaque, although it is a small seal that is old, but Jiang Yan also recognizes it: Hidden Qi Sect.

Seeing these big characters, coupled with the previous investigation in the cave, Jiang Yan already understood a rough idea.

Presumably, this Hidden Qi Sect is also a hidden cultivation sect, and the dome stone room on the second underground floor is the place where this sect's Qi refining and cultivation is located.

And there is an energy crystal hidden under the dome stone room, so the Ice and Fire Liangyi Spring at the bottom is really the cultivation secret realm of the Hidden Qi Sect.

It seems that although the ancients did not directly discover Nengjing, they also discovered the wonderful use of Nengjing through the means of Taoism, and even developed into a cultivation sect.

And this sect is hidden, there must be another reason, right?

According to Jiang Yan's inference, the Dao method of this Hidden Qi Sect should not be high, at least there are no powerful people, and in the end, most of the disciples died under the guns of the invaders of Country D.

Perhaps, it was the foreign invasion decades ago that directly led to the fall of this Hidden Qi Sect.

In Jiang Yan's knowledge system, Western countries do not have Taoist inheritance, they are admirers of classical science, and they have directly transitioned from a slave society to an industrial society through the development of science and technology.

And country D a few decades ago was the representative of classical science at that time, and they even developed anti-gravity flying devices, but the success or failure is unknown.

With such advanced thinking and research ability, it is not surprising that they discovered the secret of Nengjing.

However, it can be seen from the bones in the stone chamber that the people of country D did not bargain much at that time, and most of them were lost here, and perhaps only a few escaped.

A few decades ago, when the world order collapsed and the world was in chaos, BT, as the victorious country, directly looted all the wealth and resources of country D, among which the most important thing for them was the scientific research data of country D.

Therefore, it is the BT people who go to Huaxia to steal the treasure now, not the D people.

Jiang Yan had a rough idea of what was going on, and continued to explore, hoping to find some cultivation cheats and the like.

But in fact, he really thought too much, not to mention that the stone room he passed by before had long been empty, and even the fonts and inscriptions engraved on the walls had been damaged.

Obviously, the previous people of country D also discovered the secrets, and all the rubbings were directly destroyed.

Everywhere there were ruins and broken walls, Jiang Yan's heart couldn't help but be depressed, and he naturally gritted his teeth with hatred for these robbers.
