There was a stale smell coming from the dark tunnel, so he couldn't see what was inside.

When the stale smell was not as strong as before, Li Dao and Xing'er raised the fire piston and stepped in.

The passage was lifeless from being sealed for so long, and from time to time there were rats and cockroaches crawling under his feet, which frightened Xing'er so much that she tightened her grip on his arm. The softness annoyed him.

Li Dao did not understand how terrifying rats and cockroaches were. Most women were superficial creatures that only cared about their appearance.

They liked cute cats and dogs, and hated ugly snake rats and cockroaches. Just like how they hated slovenly and unsightly men, they liked clean and handsome fresh meat.

Sensing Li Dao's displeasure, Xing'er loosened her grip a little, but she still did not completely let go of Li Dao's arm.

This secret passageway was unexpectedly long. It took them a quarter of an hour to reach the end of the secret passageway.

Under the weak light of the fire, there was a steel door in front of them, which looked extremely thick.

Borrowing the light from the fire, Xing'er looked at Li Dao's well-defined face. His eyes flickered as he spoke, as if he was asking what she should do.

Most people could only be an idiot when it came to this sort of thing. After going through so much trouble to find the treasury, they realized that they couldn't get in without a key. However, this situation did not exist with Li Dao.

After handing over the fire piston to Xing'er, Li Dao drew his longsword and walked up. He didn't believe that this door would be able to stop him.

Perhaps ordinary innate experts couldn't do anything about this thick iron gate.

The long sword gently moved forward, the thick iron door was as fragile as tofu, holding the sword hilt and slashing left and right, easily opening a small door on the door.

Retrieving the fire piston from the dumbstruck Xing'er's hand, Li Dao stepped into it.

First, he found the oil lamp and ignited it. Then, the square secret chamber was revealed to his eyes.

Xing'er followed Li Dao into the secret chamber, covering her mouth in shock.

The room was a little messy. There was a pile of golden agate in the left corner, which was very eye-catching. On the right was a pile of sabers, arrows, and other weapons. The weapon was soaked in oil, but it still looked brand-new.

In the center of the secret room, there were more than a dozen corpses scattered on the ground. The fleshless bones were wearing blood-red monastic robes, and they looked extremely shriveled.

One of the corpses was the most eye-catching. It was wearing a monastic robe and sitting cross-legged on the ground. The monastic robe was covered in a long blood-colored dragon and a long black snake. The dragon and the snake were wrapped around it, mysterious and strange. The skeleton was leaning against a golden chest, and beside the chest was a jade box. Between its legs was a sheathed sword.

Needless to say, this monk definitely had a high status when he was alive, because the person wearing the monastic robe was either a abbot or an elder.

Li Dao had no interest in gold jewelry, not to mention swords, swords, and arrows.

He stepped forward and placed his hand on the corpse. With a crisp sound, the corpse fell to the ground.

Xing'er couldn't help but scream. She was obviously frightened by the broken bones.

Li Dao ignored Xing'er. He discovered an interesting thing. The bones scattered on the ground were sparkling and white, faintly emitting a golden luster. This represented that the owner of the skeleton was a martial artist who had reached Large Success of Body Transformation. To be able to train his bones to such a state, one could imagine how strong his body was when he was still alive, and he wasn't even fit to carry his shoes for half a month.

The bones were scattered. An envelope fell out of the robe with the dragon and snake scalding it. Li Dao bent down to pick it up and opened it. Borrowing the light of the fire, he carefully read it.

With this look, he finally understood the origins of the Evil Buddha Sect, as well as the highest level of martial power in this world.
