The secret passage twisted and curved, extending diagonally downward, and a bright yellow flame slowly moved towards the depths.

As long as Liu Zhukuai caught up with the bandits, it was enough to kill the other party, so Gu Xuan did not move quickly, such as a leisurely stroll.

Dozens of feet deep into the secret passage, Gu Xuan asked softly: "The predecessor mentioned the secret passage twice, what did you find?"

"The organs of the bamboo forest and the stone wall were laid by the same person. When bandits discover the mechanism, they will hide here. ”

Wang Mang spoke slowly.

"The two walls of the secret passage are neat, as if they were naturally formed, and the steps of the entrance and the passage are integrated, and it is obvious that they were not dug by bandits. ”

Gu Xuan pondered: "The secret path is undoubtedly a way out, and those who lived in seclusion at the beginning must have enemies. ”

That's exactly what happened. Wang Mang further analyzed, "The old man suspects that the bamboo forest agency is only in the old place, and the stone wall is the real hermitage." ”

This statement is reasonable, the bamboo forest is exposed, the fog is gloomy, and there is a mystery at a glance, but the stone wall is not. ”

Gu Xuan thought so.

"The strange shape of the stone gate matches the texture of the stone wall, and the vines cover it, if you are not proficient in civil engineering, I am afraid that it will be difficult to find. ”

Wang Mang chuckled: "Civil engineering organs have always belonged to the secret legend of the Wulin Qimen, and there are not many people who are proficient in it. ”

Gu Xuan was a little disappointed: "The secret passage is used to escape, how can there be a chance?"

Wang Mang asked rhetorically: "You only think of one side, if the existence of the secret passage is also a trick?"

"Huh?" Gu Xuan frowned, "What's the purpose of this?"

Wang Mang said bluntly: "I don't know, let's go down." ”

After going hundreds of zhang deep into the secret passage, there was a fork in the road, and Gu Xuan stopped and observed carefully.

There are no footprints at the secret passage on the left, and there are a dozen or so white footprints at the secret passage on the right, shining.

Although the secret passage is dusty, the footprints are difficult to distinguish with the naked eye, and the white footprints are caused by tracer powder.

Most of the people who go out to do errands carry tracking powder with them.

The main material of this powder is night pearl powder, which is sprinkled on the footprints and can be clearly seen.

Gu Xuan communicated a lot with Catcher on the way here, and knew about the tracer, so he immediately said: "Liu Catcher quickly pursues to the right, obviously the secret passage on the right is the way out." ”

Wang Mang immediately made an idea: "The way out doesn't make much sense, go into the secret passage on the left and take a look." ”

Of course, Gu Xuan had no opinion, and immediately walked into the secret passage on the left.

This secret passage is relatively gentle, winding, about 100 zhang long, and at the end is a flat stone wall.

"This is the stone door, take a picture of the convex stone, and you can open the door. Wang Mang advised, "Be careful, there may be a raid mechanism inside." ”

Observing the aisle before, Gu Xuan found that the lead of the crossbow arrow had traces of knots.

Apparently the bandits had triggered the trap and filled the crossbow with bolts, connecting the broken leads in a knot.

There was an irregular convex stone on the left wall of the secret passage, and Gu Xuan first drew out the Yin Flow Sword before slapping the convex stone.

With a rumbling sound, a stone door slowly sank and stopped at a height of a few feet above the ground.

Suddenly there was a click and a clatter, and three crossbow arrows that flashed with a ghostly light shot head-on.

Gu Xuan's eyes were quick, and with a few swings of the soft sword, he shot down the three small crossbow arrows one after another.

The small crossbow arrows are the same as the crossbow arrows in the aisle, and they are both fed with poison.

There was no other sound inside, Gu Xuan held a soft sword in his hand and slowly stepped in.

It is a large cave, and the light of the torches is difficult to illuminate, and the front wall of the cave is equipped with a crossbow, and the walls of the cave are equipped with mechanisms.

Half a zhang below the crossbow, there is actually a small hole, and the light from the outside is transmitted through the small hole.

Gu Xuan observed Shaoqing: "The thickness of the cave wall is less than a foot, and the true qi can easily shake open and lead to the outside. If it weren't for the mystery, this would be the way out. ”

Wang Mang pondered for a long time: "If the sunlight shines through and forms a pillar of light, where do you think it will shine?"

There was no sunlight today, Gu Xuan took a look, walked to the opposite stone wall, pointed his finger to the position facing the small hole, and moved down a little.

Wang Mang said: "Knock and see." ”

Gu Xuan knocked on the stone wall, the sound was thick, and when he knocked on the stone wall elsewhere, the sound was no different.

Wang Mang suggested: "Boxing. ”

Gu Xuan hurriedly activated his true qi, punched the stone wall, quickly retracted it, and dodged to the side.

With a bang, the stone wall did not burn into the fist print, and it was directly cracked, and the rubble flew in all directions.

Gu Xuan came to take a look, and couldn't help but show joy on his face, there was a small hole hidden in the stone wall, and there was an iron ring in the cave.

Wang Mang couldn't help but shout: "Pull the hoop quickly, the old man wants to see what mystery exists!"

Gu Xuan pulled the iron ring, and with a click, a stone bar popped out on the stone wall not far from the iron ring.

The stone strips are like drawers, and the four sides of the pop-up are all dark red, and the outermost stone slabs are irregularly shaped, which coincide with the texture of the stone walls, and are seamless.

Wang Mang hurriedly reminded: "Dark red is highly poisonous, burn it with fire." ”

Gu Xuan inserted the torch into the small hole, carefully pulled out the stone bar, and placed it on the ground.

Torches were fetched, and the stone bars were burned, and with a rattling sound, the dark red poison gradually disappeared, emitting a foul smell.

It wasn't until the stone bar regained its color that Gu Xuan inserted the torch back.

Picking up the stone bar, looking at it carefully, he found a small hole, inserted one finger into the hole, and pulled out a stone slab.

The stone bar is clearly a stone box, and a storage bag lies quietly inside the box.

"This is the chance?"

The stone box rested on the ground, and Gu Xuan stared at the storage bag with an inexplicable expression.

"Otherwise?" Wang Mang was not angry, "You kid don't want to open it?"

"It's so well arranged, it's natural to see it. ”

Gu Xuan picked up the storage bag, penetrated the true qi, and with a movement of his mind, a bundle of scrolls fell out of it.

Slowly unfold the scroll, with white jade as the shaft and silk cloth as the scroll, with dense black small characters written on it.

Gu Xuan took a quick look, and the entire text recorded the cultivation of the void strength.

The scroll divides the cultivation system of martial arts into four levels: bright energy, dark energy, transformation energy, and void energy.

The first three levels correspond to strength, internal force, and true force.

Void energy is the highest level, the power is great, it can fight with Gangqi, and it can also prolong life.

Void energy is qualitative and formless, and the cultivation in the later stage of the True Power Realm is to first disperse the true power into the body, and then incubate and transform.

At the end of the scroll, it was mentioned that the void strength might not be conducive to advancing to the Gang Force Realm, so Dao Miao was asked to cultivate carefully.

Wang Mang said quietly: "There is a legend in the martial arts of the Xi Kingdom, at the beginning of the establishment of the Great Xi Dynasty, there were warriors who created void energy, and they were able to rival the monks of the Gangli Realm, but I didn't expect that the void strength really existed. ”

Gu Xuan rolled up the scroll, took back the storage bag, and put it in his arms: "What do seniors think of Xujin?"

Wang Mang commented: "Returning to the basics, breaking through tradition, subverting the system, and opening up a new face, although the founder is unknown, he is an immortal genius." ”

"It's a pity that the weak energy affects the advancement of Dao Miao, and my spirit is not inferior at all, and I can't tolerate the slightest difference. ”

Gu Xuan filled the stone box into the stone wall, restored it to the original, and picked up the gravel, blocked the small hole, and covered the iron ring.

"Everything can't be generalized, what kind of void strength is, when you advance to the later stage of the True Power Realm, you will know it by trying. ”

Gu Xuan thought about it for a while, and put the three crossbow arrows back into the machine crossbow, after all, it was a masterpiece left by his predecessors.

With a slap of the convex stone, the stone gate rumbled up, and although the stone wall was shattered, it did not affect the operation of the mechanism.
