Mo Yinghan and the others, who turned back along the secret passage at the Buddha statue, were destined to return in vain, because Mo Yinghan himself could not have imagined that in the underground secret room he built, there was another unknown secret passage, that is, the secret passage used by Chen Shaojie's subordinates when they left.

Su Mu originally thought that the mysterious man under Chen Shaojie had some kind of secret method of his own, which could turn into a black mist and disappear directly out of thin air, but he didn't expect that the black fog was just a trick to cover his eyes, and at the moment of releasing the black mist, the man opened this secret passage and fled directly.

This secret passage was in the middle of the underground secret room, because the light was extremely dim, ordinary people could not see the traces of its edge at all, but Su Mu, who had superhuman senses, was very keenly aware of this.

When Su Mu confronted Mo Yinghan and the others, he found out that the Qingyanguo stranger who was seriously injured by himself before did not actually disappear out of thin air, but when he fell heavily to the ground, he coincidentally opened this secret passage and fell into the secret passage, the entrance of this secret passage is extremely hidden, and it looks completely no different from the surroundings, and it can only be trapped in it after a large force.

At the moment when the blue sky shadow was slashed by Mo Yinghan, Su Mu did not miss this fleeting opportunity, and jumped directly into the top of the other secret passage he had just found, and after pedaling hard, he drilled into the secret passage.

Before jumping in, Su Mu didn't forget to swing a sword wind in the direction of the dark path behind Mo Yinghan, so as to create the illusion that he was fleeing the original path of the Buddha statue.

Because of the stimulation of the strong light, Mo Yinghan not only lost his sight for a few breaths for a while, but even his senses became dull for a while, and he himself didn't know the existence of this secret passage at all, so he took it for granted that Su Mu had escaped the same way, and chased after him without thinking.

As soon as he entered the dark passage, Su Mu immediately found the stranger who had been seriously injured and unconscious, and he didn't know when the stranger might wake up, so he had to kill it without stopping, and then slowly explore forward.

At this time, Su Mu, who was in the dark passage, was not very comfortable, the dampness and dullness of this dark passage was far greater than the one outside, and the space was also compressed even more, and it was very difficult for one person to pass.

Su Mu was a little out of breath as he walked, and he had hesitated whether he should wait for Mo Yinghan and the others to leave before returning to the underground secret room and returning the same way, but if Mo Yinghan didn't find his trace at the entrance, it must be easy to think that he should still be hiding in this underground secret room, and if he turned back at that time, he would really have nowhere to escape.

After weighing the pros and cons a little, Su Mu finally decided to explore the secret path taken by Chen Shaojie's subordinates.

The dark path went deeper and deeper, but there was no intention of reaching the end, there were several forks in the middle, and it was easy to lose a sense of direction in the dark, Su Mu concentrated and completely left his body's intuition to judge the direction to ensure that he always walked to the straight.

The dark passage had some subtle downward arcs, and Su Mu felt that he was gradually getting deeper and deeper, and the length of this dark passage was also significantly longer than the one just now.

"This secret passage won't lead directly to Zuo Xiang's mansion, right?" Su Mu muttered in his heart, if he walked all the way back to Luojing from the Ziji Temple, the project of this secret passage would inevitably be a little too big.

I don't know how long it has been, there is finally a light ahead, Su Mu carefully controls his breathing and pace, I don't know if there is an enemy in front of me, Su Mu must be extra cautious.

This is a completely different space from the previous underground cavern, the area is huge, and the zenith is also higher, intuitively it is more than ten times the size of the secret room. Although there are stone walls all around, you can see a lot of purple shiny protrusions in the cracks.

What kind of spar is this? Su Mu stretched out his hand and touched it, the hardness was very amazing, even if he cut it with the Qingshuang Sword, he didn't leave any traces.

"Is this really artificially built?" Su Mu couldn't believe that such a cave could have been dug by people, the soil around here was extremely hard, and there were spars that couldn't even be broken by sword qi, could anyone really dig such a big cave in this environment?

Although there was no one else in the cave, Su Mu still explored very carefully, and after searching for most of the day, he did not find any other exits in the cave.

It's a headache, if you want to go back the way you came, where can you remember the specific route, do you go straight back to the previous entrance to the underground secret room?

Thinking of the narrow and stuffy secret passage, Su Mu was really reluctant.

If you take a closer look, maybe there are other mysteries hidden in this cave.

Su Mu thought calmly, the scale of this cave was obviously unlikely to be built by someone on purpose, not to mention how much movement such a huge amount of work would bring, under such a deep underground, it could be said that it was very difficult to breathe, let alone start construction.

But if it wasn't artificially created, could this intricate underground passage be a natural formation?

Su Mu looked towards the end of the cave, and suddenly found an inconspicuous crystal stone platform, which was standing high, Su Mu took a closer look, the stone platform was more than ten meters high, and it was also covered with various large purple crystals.

Could it be that there is something on this stone platform that can't be done?" Su Mu thought to himself, carefully stepping on the protrusion of the crystal, and climbed up with difficulty.

Because the distribution of purple crystals is very irregular, and the air under the ground is very thin, it can be said that it is extremely difficult for Su Mu to climb at this time, and he is about to fall down several times in the middle, or he is scratched by the purple crystal, but Su Mu still gritted his teeth and persevered.

Finally climbed to the top of the stone platform, only to see that in the center of the stone platform there is a very delicately made wooden table, the years and the humid and sultry air in the cave have already corroded the wooden table to the point that it is not visible, the wooden table is engraved with two lines of words that have been eroded to the point that it is not clear, and there is a simple small box on the table.

The moment Su Mu saw the small box, he felt that the blood in his body was boiling, and the sword sound that he hadn't seen for a long time in his mind was also restless again, and he gasped heavily, trying his best to calm his mood.

It's just because this small box looks exactly the same as the Taibai True Meaning Clever Box that he has been carrying with him all these years and has obtained from the Drunken Immortal Residence.

Could it be that this is another Taibai true meaning box left by Taibai?

Su Mu couldn't help but take out the small box that had been properly kept from his clothes, and carefully compared it, except for the different degrees of erosion in appearance, the size, workmanship, and design were almost exactly the same.
