Another hour later, Yu Xingwu and his group were already in the tomb passage on the ninth floor and had searched all nine floors.

Even the tomb chambers were searched one by one, leaving only the tomb chamber behind the black iron stone door in front of them unsearched.

Everyone stared at the huge black gate, with solemn expressions on their faces.

Ye Su: "Master, we have come all the way here without finding anything. Logically, the passage to the underground should be on the ninth floor of the mausoleum, but no abnormalities were found in other tombs, so this is the only tomb that has not been searched."

Yu Xingwu naturally understood what Ye Su meant. There was nothing unusual in other places, so there was probably something strange about this tomb.

Otherwise, the direction calculated by Jiang Yan and Su Zisheng was wrong, and the way to the underground was not here.

Jiang Yan: "Shen Er, you come and break this black iron door. I see that the branch in your hand is quite useful, so I'll leave this door to you."

"When we go in later, we must search thoroughly. I have a hunch that the way to the underground is in this tomb!"

Yu Xingwu's eyes fell on the branch in Shen Zhuo's hand. It seemed familiar to her no matter how she looked at it.

[Tong, is this the branch I broke off for him before? ]

System: "It should be the host. I didn't see your dear Taoist companion breaking branches along the way, which shows that he carried this branch with him and brought it into the mausoleum."

"Tsk tsk tsk, this dog food caught me off guard!"

Ye Su: My natal sword is left at the Imperial Master's Mansion. If I had known this, I would have asked my junior sister to break one for me on the way here.

Seeing that the branch in Shen Zhuo's hand was covered with a layer of sword spirit, Yu Xingwu immediately suggested: "Brother Su, Fourth Brother, Sister Su, do you have any soundproofing notes?"

"Destroying this black iron gate will definitely cause a lot of noise. If we can block out the sound, we won't alert the Imperial Master and those demon cultivators."

Upon hearing this, Jiang Yan and the other two took out their soundproofing magic weapons.

As a talisman practitioner, how can you be without various talismans on your body? Soundproofing sounds are a must!

Su Qianning: "Okay, Junior Sister, the soundproofing device is ready to use. Senior Brother Shen can break the door now!"

"Bang--!"

There was a loud bang, followed by a trembling sound that echoed for a long time.

The black iron door that was so solid just now had now been cut open by the sword energy.

Jiang Yan was an impatient man. Without the obstruction of the black iron gate, he rushed into the tomb immediately. He had long forgotten Feng Chen's instructions and decided to walk in front, saying, "I'm not afraid."

Yu Xingwu and his group also followed in. When they entered the tomb chamber, the first thing they saw were four coffins.

Yu Xingwu guessed that the four coffins were placed in a tomb chamber, and the four owners in the coffins were probably the four favorite concubines of a certain emperor.

But they were not looking for dead human fetuses, and they were not very interested in these coffins. They searched the entire tomb but did not find any secret mechanisms.

Jiang Yan: "How can there be no passage to the underground! My divination cannot be wrong. The tomb is in the northwest direction, and the passage is probably here!"

"If my guess is correct, the passage to the underground may be inside these four coffins!"

"Shen Er, Senior Brother Ye, Boss, open the coffins! Open them all! I don't believe we can't find the mechanism!"

Su Zisheng hesitated: "Old Four, aren't you afraid of startling the corpse?"

Jiang Yan made a "Pooh" sound, thinking that Su Zisheng mentioned everything that shouldn't be mentioned.

"Why are you disturbing the corpse? The Sword Master is here. If anyone dares to disturb the corpse, I will chop him into pieces!"

Yu Xingwu's mouth twitched, and she said secretly: [Fourth Brother, when it comes to courage, you are still the bravest! ]

Just as he finished saying this secretly, he saw an even more courageous scene - Shen Zhuo directly grasped the long sword, bah, grasped the tree branch, and split all four coffins in half!

Everyone was shocked. Yu Xingwu was completely stunned, with only the corners of her mouth twitching.

I thought: [As expected of you, the villain! Even braver than the fourth brother! Whose subordinate is this!]

[If you don’t know, you might think that the people in these four coffins have a grudge against you and have cheated on you! ]

Feng Chen: "..."

Ye Su: "..."

Shen Zhuo: "..."

system:"……"

Little Rabbit: "..." Sister, do you know that when you said this, it seemed like you were the one being cuckolded!

At this time, Jiang Yan and his group also gathered in front of the four split coffins, but heard Su Qianning said in surprise: "It's an empty coffin! All four coffins are empty!"

Ye Su: "It's not surprising that it's an empty coffin. There is a saying among human burials that empty coffins are buried, and there are indeed empty coffins in the tombs of some mausoleums."

"But the result of Junior Brother Jiang's divination is that there is a passage leading to the underground. Junior brothers and sisters need to search carefully to see if there are any hidden mechanisms in the coffin."

"Don't move, let me do it! It's unlucky to search in a coffin, just watch me!"

As Jiang Yan spoke, he had already thrown out several fire talismans. The fire talismans burned in the middle and fell directly into the four opened coffins.

If he had known that the coffin was empty, he would have used the fire talisman to burn the coffin at the beginning, and Shen Er would not have to do anything!

After all, it was a fire talisman, not just an ordinary torch. Soon the four coffins were burning.

The flames were blazing, the fire was vigorous and fierce, but it was smoky and a bit choking!

Feng Chen waved his hand and instantly set up a barrier that covered everyone and also blocked out the billowing smoke.

The fire talisman was indeed powerful. Soon the four coffins were burned out. When the smoke dissipated, Feng Chen also removed the barrier.

I saw that where the four coffins were originally placed, one of the floor tiles was carved with a lotus pattern, four identical lotus patterns.

It is obvious that the appearance of four identical patterns under the coffin is very wrong, and it is very likely that there is some trick in the arrangement.

If we open the key point, perhaps we can open the passage to the underground.

But when Jiang Yan and others pressed on them, the four floor tiles did not show any reaction at all.

Yu Xingwu thought to herself, after all, he has read a lot of online novels. Besides being a great actor, his brain circuits are also top-notch!

I have to make a deduction: [Lotus, lotus blooms with every step, it has something to do with feet, four empty coffins, missing people. ]

[Does that mean that as long as four people stand on the floor tile with lotus engraved on it, the mechanism can be triggered? ]

When Feng Chen, Ye Su and Shen Zhuo heard what was in their mind, their eyes lit up, and the three of them walked to three of the floor tiles tacitly.

Seeing this, Yu Xingwu exclaimed: [Master! Look! The three of them thought the same as I did! They are so in sync! This is enough to prove that my guess is correct! Maybe this is how the mechanism was opened!]

Shen Zhuo: We are in perfect sync with each other. I just want you and I to be in perfect sync with each other, and no one else.

Yu Xingwu was a person of action, so after Feng Chen and the other two walked onto the three floor tiles, she followed them up.

Jiang Yan, Bai Ran and others also guessed from the actions of the four people that they were testing whether they could open the mechanism.

The next second, a strange "click" sound was heard, and a circular crack appeared in the center of the square where the four people were standing.

Then there was a loud "boom" and the entire round floor tile began to sink.

The reason why there was no response when I pressed it with my hand just now is because it takes the weight of a person to open the mechanism, and it requires four people.

System: "So, if we had asked four people to stand in the coffin, we could have triggered the mechanism."

Yu Xingwu: [Bad luck! Didn’t you hear what Fourth Senior Brother said? It’s too unlucky for a living person to be put into a coffin!]

There was a constant shaking sound inside the tomb until a long staircase with no end in sight appeared, and the sound stopped.

Undoubtedly, this long staircase with no end in sight is the passage leading to the source of the underground dragon vein.
