At this moment, three roads appeared in front of Ye Guan, and the messy footprints I discovered before gathered from two of them and merged into the middle road.

This underground cave was obviously dug by manpower to achieve a certain purpose. This purpose should be aimed at the Eastern Palace.

"No wonder I haven't found any trace before, and I didn't expect to use this trick." Ye Guan glanced at the left and right passages. The dark passages could not see the end at all, like two black beast mouths, swallowing everything.

After his mood moved, Ye Guan turned his gaze to the middle channel, and the footprints on both channels finally gathered here, so this channel may have a huge secret.

But Ye Guan did not enter immediately, but just retreated quietly, his breath was restrained, and his retreat was very fast. Without much effort, he left the cave and came to the dense jungle before.

Leaving a secret mark on the trees beside the jungle, Ye Guan turned his head and followed the footprints on the grass before, slowly moving forward.

In the cave, three passages were obviously seen gathering into the middle passage. This should be the instructions received by the people from the two passages and then entered the middle passage. However, the footprint that Ye Guan discovered before came out of the cave.

In other words, the entrance he discovered now should not be an entrance, but an exit.

Besides, the underground passage is extremely hidden. If he had not discovered a series of footprints, he would have definitely not be able to find the cave passage. However, Ye Guan carefully analyzed that the three scouts of Lenovo had disappeared out of thin air, and he could not find the underground passage after investigation. Therefore, he felt that the other party would not make such a mistake. If this person who came out of the cave did not do this on purpose, he should have received some urgent orders, so he had no time to hide his traces.

The underground passage is hidden, and there must be many dangers hidden in it. Before we figure out how this passage is used, Ye Guan will definitely not go deeper easily. He has seen the gathering of three passages, which basically proves his guess. It is better to follow this footprint and see what will appear in front of you.

Ye Guan changed his fighting spirit and walked quickly through the grass. His speed was much faster than in an underground cave. After a while, he came to the place where he first saw the footprint. Ye Guan stopped, possessed himself in the grass, scattered his senses and sensed everything around him. After confirming that there was no abnormality, he rushed forward quickly along the grass.

The footprints kept going, as if they were drawing circles before. If Ye Guan had not made any mistakes in the calculation, the footprint was moving upward from time to time, and Ye Guan had been following the footprints. At this point, he felt that he was almost at the top of Zongqiu Mountain.

His brow frowned slightly. Although he determined that the direction of the footprint might be directly pointed to the peak, Ye Guan did not change his course of travel. He did not think that anyone would be so stupid. He exercised in this wilderness and circled around a mountain range. The reason why this person walked like this was definitely a path planned in advance. If he left this route, he would probably encounter unexpected things.

It is possible to trigger the warning mechanism or to set out a secret trap. Of course, he is fearless in both of Ye Guan's skills. What he is most worried about is that if he leaves this route and triggers straight to the top of the mountain, he is likely to touch the killing formation and poses a fatal threat to himself.

As he approached the top of the mountain, the footprints became shallower and the surrounding trees and grasslands became increasingly sparse. The number of trees was much smaller than that at the foot of the mountain, which also made it increasingly difficult for Ye Guan to hide his body. However, Ye Guan still kept hiding his body to avoid alarming the snake.

The purpose of his separate trip this time was not to break the enemy's ambush, but to figure out what the enemy was doing. With his own strength, it was impossible to crack the entire Zongqiu Mountain ambush.

When we were about to reach the top of the mountain, the grass and trees around us were already very sparse, and the footsteps I had followed along the way had disappeared, and there were no traces of people passing by around us. Everything disappeared very suddenly, which made Ye Guan frown slightly.

Ye Guan possessed himself in a grass, calming his mind and spreading his perception, but he did not find anything wrong. However, the footprints in front of him disappeared very suddenly, which made Ye Guan suspicious.

Slowly circulate the Dou Qi, a faint blue light spot slowly appeared, condensed on Ye Guan's middle finger. Curled up his fingers and aimed at the place where the footprints disappeared, and gently bounced. The light blue light ball flew out quickly and shot straight toward the footprints.

However, there was no imagined light sound, and this light green light ball disappeared out of thin air. It seemed as if at this moment, it was swallowed by something.

Ye Guan frowned slightly, and an idea immediately appeared in his mind.

"Illusion Barrier." Ye Guan frowned slightly, and he thought of this possibility at the first time.

The illusion barrier is one of many formation barriers. It does not have the ability to directly block things, but it can transform into an environment, making people see no clues at first sight, thereby blocking things behind the barrier. This barrier is also called a slut, and is a relatively low-level one among the illusion barriers. However, although it is low-level, it is indeed effective at some time to use it, such as now.

If Ye Guan hadn't discovered a series of footprints and followed them up the mountain to come here, he would never have expected that there would be an illusion barrier here. Because from a distance, it would be like an ordinary mountain range, without any abnormality.

This barrier has also appeared outside Tianqing City. In the eyes of the world, the appearance of Tianqing City is actually a illusion barrier. The real Tianqing City is not on that mountain at all. There are only teleportation formations on that mountain.

"No wonder." Ye Guan frowned and said to himself: "No wonder all scouts can't see any abnormalities. No clues can be found within thirty miles. It turns out that there is such a trick."

After thinking about it, Ye Guan was a little heavy-hearted. The enemy was doing so many things with great strength, and it was an underground passage and an illusion barrier. No wonder the three teams of scouts he sent had no news. However, even if they could go back safely, they might not be able to find the secrets hidden in the mountains. He also accidentally discovered these footprints, so that he could find these hidden secrets.

The illusion barrier is usually accompanied by a warning formation. If Ye Guan enters this barrier directly, it will inevitably trigger the warning formation. People inside the barrier will immediately know that someone is invading.

"No wonder, from the bottom of the mountain, there was not a single beast. So that's it." Ye Guan narrowed his eyes slightly. Although he had a profound cultivation level, he did not understand formations. Even if he knew the principle of formations, he could not cultivate without the affinity of talismans, and let alone crack them. Although Ye Guan's Zhiguan's palace was wise and had no achievements in formations. He could recognize the formations in front of him, and he also communicated with Zhimo Ning Yi through many ancient books and previous exchanges with Zhimo Ning Yi.

With his mind moving slightly, Ye Guan left a mark in a hidden place, held his breath and slowly retreated.

The enemy has arranged an illusion barrier in such a hidden place, and there must be something in it, but Ye Guan cannot rush in alone now, so it is meaningless to do so. Moreover, he does not know what is hidden behind this barrier. If there is a killing array hidden behind it, once he enters, he will immediately trigger and die of a bad life.

Having discovered the situation, Ye Guan gently retreated, came to the previous road, and ran back quickly along the footprints on the ground.

Since you cannot break the illusion barrier, you can only return and first clarify the specific purpose and vertical and horizontal direction of the underground passage, which will be of great help to future attacks.

After a day of tracking, when Ye Guan returned to the entrance of the cave again, it was already the scorching sun. In the afternoon, he stood quietly at the entrance of the cave. He did not lift the lawn covered on it as soon as possible, but extended his perceptions in, carefully investigated, and confirmed that there was no danger. Then he lifted the lawn and jumped in.

After entering the cave, Ye Guan stood up, rolled up the lawn covered outside, and covered it on the cave again, creating an illusion that no one discovered. Then he touched the rock wall of the cave and walked forward.

This time he went forward, he did not call for Douqi lighting to prevent the attack on the enemy.

Ye Guan thought in his mind that this passage was not often used, and might only be used to convey secret messages in emergencies. There are also strange routes to the mountain, and there is even an illusion barrier on the top of the mountain. Thinking of this, the place where the passage in front of him is likely to be the gathering point of the enemy.

He vaguely guessed in his heart that at the end of the cave, many enemy soldiers might have gathered, hiding in this underground passage, waiting for the attack of the Eastern Prince's Mansion.

He was calculating what might happen in his mind. Ye Guan touched the rock walls on both sides and quickly moved forward. After walking for about a quarter of an hour, he arrived at the previous fork. This time, Ye Guan did not hesitate and entered the fork in the middle.

He walked forward for more than a quarter of an hour. At the end of the cave, Ye Guan faintly saw the dark candlelight coming, which made him fall to the ground in his heart, hold his breath and look forward carefully. However, he saw that there was no one coming from the distance in front of him. There should be a wall light at the turn of the passage in front, and the dark candlelight at this moment was probably the wall light coming from.

After eliminating the danger, Ye Guan let out a sigh of relief. In such a deep cave, Ye Guan went alone, and the road ahead was not known, and the retreat was very far behind. It was impossible to say that Ye Guan was not nervous. Even though he had been through many battles, he was extremely cautious at this moment. If someone discovered it in this cave, he would say he was in an extremely difficult situation.

He held his breath and moved forward more carefully. The dark candlelight in front of him became brighter and brighter. Ye Guan walked to the corner of the cave and leaned over to the ground. He felt it carefully with his perception and found that there was nothing abnormal. Then he poked his head out and looked beyond the turn of the cave.

But the situation in front of Ye Guan was surprised.

In front of me is a wide underground secret room filled with various war materials, bows, crossbows, arrows, armor and weapons, and even a suggestion catapult was found in a corner.

There are a few candle lamps hanging on the rock walls around this secret room, illuminating the entire secret room. In the middle of the secret room, a not-wide passage leads straight to the front. At the end of the passage is a wooden door. From the perspective of Ye Guan, the texture of the wooden door cannot be seen, but based on guessing alone, it is known that this wooden door should be extremely tough.

This secret room was obviously used by the enemy to collect materials. Judging from the traces on the ground, someone passed by this not long ago.

Ye Guan frowned and said to himself: "It seems that the first line of defense prepared by Shen Tuyan for me was actually this underground cave. He hid all the soldiers in this cave and isolated them from each other. In this way, even if our soldiers found the entrance to the cave, they could not catch them immediately. With the wooden doors like this in front, they would probably not have a good effect if the fire attack was not effective."

Ye Guan's eyes were faint and looked at the wooden door not far away. At this moment, the wooden door moved.
