A crack broke open on the cliff, revealing a deep tunnel.

"Let's go!" The elder in charge greeted everyone, then lit the torches and walked in, and the other elders followed closely.

Seeing that the elders had all entered, and the cracks on the cliff were about to close, Jiang Fei followed in with a flash. He was decorated with these elders from afar, walking in the dark tunnel. Although Jiang Fei had no light source, fortunately, his night vision ability was strong, so he could see the road in front of him clearly.

Following these elders, about ten minutes later, Jiang Fei entered a hall, and then the elders gathered in front of a stone pillar. They all turned their backs and stood outwards, forcing Jiang Fei to find a corner to hide. Although it was invisible, Jiang Fei was still unwilling to take risks.

Then Jiang Fei found that one of his elders turned around. He touched a special position at the stone pillar, and then returned to the position he had stood before, and continued to stand with his back to the stone pillar. He followed the second elder and began to repeat the man's operation before. Next was the third and fourth...

Soon, all the elders touched a special position at the stone pillar, and then Jiang Fei heard the mechanical transmission sound of Galala again.

"I'll go! Is there a password? And it's also a separate grasp?" Jiang Fei was a little stunned. These elders were too cautious, right?

But thinking about it, the meaning of the existence of this Presbyterian Church is to ensure that the treasure house of seal technology is not opened, and that their ancestors will not do anything else for generations, so they are all thinking about this.

With the sound of mechanical transmission, the stone wall on one side of the hall flipped, and there was a small platform on the back of the stone wall, and a wooden brocade box was placed on it.

After seeing the brocade box, a group of elders came over. They carefully opened the brocade box and looked inside.

"Huh...fortunately, I didn't lose it..." The elders breathed a sigh of relief.

"I said it's okay? It's so hidden here, how could they steal the keys?"

"Hmph! That's not what you said before!"

"Okay, OK, the security of the key has been confirmed, let's go."

"Well! Let's go! If you stay here, don't be discovered!"

"Do you think they were trying to bring us here on purpose?" Suddenly, an elder suddenly spoke.

"Ah?!" The remaining elders were stunned.

"Look, we hid the key so hidden, outsiders must not know it, but they deliberately claimed that they had obtained the key, but we ran over to see it. If someone was following us secretly, wouldn't they have discovered this?" said the elder.

"It makes sense!"

"Hey! I'm impulsive..."

The other elders were talking.

"Now is not the time to talk about this. The question is, what should we do?" the elder asked.

"Or we will take the key away?" an elder suggested.

"If those people block us outside the door and we go out with the keys, wouldn't that be your own way?"

"And no one stopped us. Where can I put the keys after I took them out? I'm afraid it wouldn't be safe if I put them in anyone's hands? We can't build another place as safe as here in a short period of time!"

"yes!"

"What should I do..."

The elders were once again confused.

"Actually, I don't think we need to take away the keys!" said a young elder at this time.

"Huh?" Everyone looked at the young elder.

"Look, if we put it back, as long as the mechanism is detained, they will never find where the key is hidden. If we find that stone pillar, as long as we are, one of us can withstand the coercion and temptation and refuse to say the password, the key is safe!" said the young elder.

"It makes sense!" The other elders nodded.

Because the stone wall where the key is located is very thick and the stone material is extremely strong, it is almost impossible to open it with manpower. Although the stone pillar and the password may be leaked because an elder cannot withstand the threat of threats and temptations, the password is kept by all elders. As long as there is one who refuses to say the password, the mechanism cannot be opened, so it is relatively not difficult to keep the secret of the key.

"There is no good idea at the moment, so I can only do this!" The other elders nodded in agreement with the proposal.

Then the people put the key back to the wooden box, then reversed the mechanism, and let the stone wall hide the wooden box back.

"Let's go, let's go out!" said the elder in the lead.

"Okay!" The other elders nodded one after another, and then a group of people left the secret room on the mountainside one after another.

After leaving the secret room, the elders took their tokens back one after another, and then they quietly returned to the capital. What surprised the elders was that they were not arrested and no one stopped them. Su Che and Su Rui did not intend to attack them.

While the elders were worried, Jiang Fei was still in the secret room.

"Password? It doesn't need to be that complicated!" Jiang Fei smiled slightly, then waved his hand and summoned the Chengying Sword.

"Buzz!" The metallic spiritual power covered the Chengying Sword, and then Jiang Fei's wrist was shocked.

"Slay!" With a slash of shouts, the Chengying Sword slashed on the stone wall, bringing up a string of sparks.

"Hiss! So awesome!" Jiang Fei took a breath of air. The stone wall was not split into a hole as he thought, but only a shallow mark was left.

"Swish!" After seeing that the Chengying Sword could not split the stone wall, Jiang Fei took back the Chengying Sword, but he was not worried too much.

Then Jiang Fei took two steps in front and put his hands on the stone wall, while his spiritual power began to change continuously in the five elements.

Jiang Fei was trying, and he wanted to make his spiritual power the same attributes as the stone wall, and then vibrate at the same frequency, which would resonate with the stone wall.

Soon, Jiang Fei's spiritual power was locked in the metallic nature, and then he began to constantly adjust the vibration frequency of the spiritual power. At the same time, Jiang Fei's violet eye opened, and he began to carefully observe the properties of the stone wall and look for its vibration frequency.

Under the violet's eyes, the stone wall gradually becomes microscopic and particle, and eventually becomes a series of energy strings.

These energy strings constantly vibrate, and then form special particles, which eventually form a solid stone wall.

"Zheng!" Jiang Fei began to try to use spiritual power to pluck the energy string. He used mental power before, but at this time, mental power could not be released, so he had to try to use bulky spiritual power to do this delicate thing.
