Another hour later, Yu Xingyu and her party were already in the tomb on the ninth floor, and searched the ninth floor.

Even the burial chamber was searched one by one, and only the burial chamber behind the stone door made of black black iron in front of him had not been searched.

Everyone stared at the huge black gate, and their faces were solemn.

Ye Su: "Master, we have not found anything along the way, it stands to reason that the passage to the underground should be located on the ninth floor of the mausoleum, but there is no abnormality in the other tombs, and only this tomb has not been searched."

Yu Xingyu naturally understood what Ye Su meant, there was no abnormality in other places, and there was a high probability that this tomb was strange.

Otherwise, Jiang Yan and Su Zisheng's calculation of the direction is wrong, and the way to the underground is not here.

Jiang Yan: "Shen Er, you came to break this Xuantie Gate, Lao Tzu saw that the branch in your hand was quite good, and this door will be handed over to you."

"Let's go in later, we must search and search, Lao Tzu has a hunch, the road to the underground is in this tomb!"

Yu Xingwei's gaze fell on the branch in Shen Zhuo's hand, how to look at it and feel familiar.

[Unity, isn't this branch the one I folded to him before? 】

System: "It should be the host, I haven't seen your relatives break a branch along the way, so it can be seen that this branch was carried by him and brought into the mausoleum."

"Tut-tut, this dog food, I was caught off guard!"

Ye Su: My natal sword was left in the National Teacher's Mansion, and I knew that on the way to come, I also asked the little junior sister to fold one for me.

Yu Xingyu saw a layer of sword intent attached to the branch in Shen Zhuo's hand, and immediately proposed: "Senior Brother Su, Fourth Senior Brother, Senior Sister Su, do you have a soundproof note on your body?"

"Destroying this Xuantie Gate, the movement will not be small, if you can isolate the sound, you will not alarm the national teacher and those demon cultivators."

When Jiang Yan and the three of them heard this, they all took out the soundproof magic weapon on their bodies.

As a talisman cultivator, how can there be all kinds of spiritual talismans missing from his body, and there must be soundproof talismans!

Su Qianning: "Okay, little junior sister, use the soundproof note, Senior Brother Shen can break the door!"

"Bang ——!"

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

The Xuantie Gate, which was still extremely strong, had been slashed open by the sword qi at this moment.

Jiang Yan is an anxious man, without the obstruction of the Xuantie Gate, he immediately rushed into the tomb, he had long forgotten the instructions to seal the dust, and he was not afraid of a Lao Tzu, so he had to walk in the front.

Yu Xingyu and her entourage also walked in, entered the tomb, and saw four coffins at a glance.

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

But they weren't looking for dead people, and they weren't interested in these coffins, but they searched the entire tomb, but they didn't find any secret tricks.

Jiang Yan: "How can there be no passage to the underground!" Lao Tzu's divination will not go wrong, in the northwest direction, this tomb is in the northwest position, and the passage is probably here! ”

"If Lao Tzu guessed correctly, this passage to the ground may be in these four coffins!"

"Shen Er, Senior Brother Ye, boss, open the coffin! Open all! Lao Tzu doesn't believe that he can't find the mechanism! ”

Su Zisheng hesitated: "Fourth, you are not afraid of shocking corpses!"

Jiang Yan snorted, only thinking that Su Zisheng should mention anything that should not be mentioned.

"What kind of corpse to be shocked, there is a sword venerable here, whoever dares to shock the corpse, dare to surprise one, just dismantle it in eight pieces!"

The corners of Yu Xingwei's mouth twitched, and she said secretly: [Fourth Senior Brother, if you want to say brave, you are still brave! 】

As soon as he finished speaking secretly, he saw a braver scene - Shen Zhuo directly held the long sword in his hand, phew, held the branch in his hand, and split all four coffins!

Everyone was shocked, Yu Xingyu was stunned with a whole flax, only the corners of her mouth were cramping.

Heart: [It's you, the villain!] More courageous than the fourth senior brother! Whose subordinates are this! 】

[I don't know, I thought that the people in these four coffins had a grudge against you, and they all brought you a green hat! ] 】

Dust: "......"

Ye Su: "......"

Shen Zhuo: "......"

System: "......"

Little Rabbit: "...... sister, do you know that when you say this, it seems that you are the one who is cuckolded!"

At this time, Jiang Yan and his party also gathered in front of the four coffins that had been split, but they heard Su Qianning say in surprise: "It's an empty coffin!" All four coffins were empty! ”

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

"But the result of Senior Brother Jiang's divination is that there is a passage to the underground, and you junior brothers and sisters still need to search carefully to see if there is a secret trick in the coffin."

"Don't move, let Lao Tzu come! How bad it is to search in the coffin, look at Lao Tzu! ”

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

If he had known that the coffin was empty, he would have used the fire charm to burn the coffin at the beginning, and he didn't need Shen Er to do it!

In the end, it was a fire charm, and it was not unusual to throw a torch, and soon the four coffins were on fire.

The raging fire was beating, the fire was strong and violent, it was smoky, and it was a little choking!

Feng Chen waved his hand, and instantly laid down an enchantment to envelop everyone in it, and also isolated the billowing smoke.

In the end, the fire talisman was powerful, and it didn't take long for the four coffins to burn out, and when the smoke cleared, the dust was also removed from the enchantment.

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

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

Open the barrier, and you may be able to open a passage to the underground.

It's just that when Jiang Yan and the others pressed it with their hands, they didn't see the slightest reaction from the four floor tiles.

Yu Xingyu secretly wondered, in the end, she is a person who has read a lot of online novels, in addition to being a drama spirit, her brain circuit is also first-class!

Hard reasoning: [Lotus, step by step, is related to the feet, four empty coffins, lack of people. ] 】

[Does that mean that just four people standing on the tiles engraved with lotus flowers can trigger the mechanism?] 】

When Feng Chen, Ye Su, and Shen Zhuo heard their hearts, their eyes couldn't help but light up, and the three of them actually walked to the three of the floor tiles in tacit understanding.

Seeing this, Yu Xingyu shouted: [Unification! And lo and behold! The three of them were the same as I thought! It's really a little bit clear! It's enough to prove that my guess was right! That's how the mechanism works! 】

Shen Zhuo: It's easy to have a soul in your heart, I just want you and I to have a soul, and there is no one else.

Yu Xingyu was originally a man of action, and after the three of them walked to the three floor tiles, they also followed.

Jiang Yan and Bai Ran also guessed from the actions of the four of them that the four of them were doing this to test whether they could open the mechanism.

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

Immediately after that, there was a "boom", and the whole round floor tile began to sink downward.

And there was no response when I pressed it with my hand, because it required the weight of one person to open the mechanism, and it required four people.

System: "So, if you find four people standing in the coffin just now, you can also touch the mechanism."

Yu Xingyu: [Mildew, didn't you listen to what the fourth senior brother said, it's too bad for a living person to enter a coffin! ] 】

Inside the tomb, the sound of vibration continued until a long staircase with no end in sight appeared, and the sound did not stop.

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