With the innate power of the Thunder God Sword, Chen Lin could easily activate the stone slab.

Immediately, thin lines appeared in the cave, forming a mysterious figure in the center.

Chen Lin looked at the pictures and had endless reveries in his heart.

According to the description in the classics, there are no ordinary places where regular spells can be used. Since this transmission channel uses regular spells, it is very likely to lead to an advanced interface.

But there are too many advanced interfaces.

The legendary spiritual world, fairy world, divine world, demon world, Buddhist world, etc., are all advanced planes.

There are also other cultivation systems, such as the proud world where Connie lives, the wizard world of the wizard system, and even high-level scenes in the demon world, which are all possible.

But what Chen Lin is most worried about is directly teleporting out of the original domain and entering the 'real world'.

He has not yet formed his true source. According to Zi Shu, once he leaves, he will be directly annihilated!

So we need to investigate clearly before talking about it.

The reason why he found an experienced cultivator from the real world and a creature from the demon world was to make sure nothing went wrong.

"Okay, Zhang Tiansheng, you come first!"

Chen Lin gave instructions to the old cultivator brought in from the real world.

The old cultivator had already received the huge benefits promised by Chen Lin. Even if he died, he would give the treasure to his son, so he went directly to the rules and pattern without any hesitation.

But what made Chen Lin frown was that as soon as the opponent approached the regular pattern, he was immediately bounced back. Let alone entering it, even if he wanted to touch it, he couldn't.

"Try again!"

He spoke in a deep voice.

The old cultivator nodded, his magic power reached its limit, and he approached again.

But the result is still the same, it bounces back before it gets closer.

Then the veteran cultivator used several other methods, but to no avail.

Chen Lin looked ugly. It would be fine if it was because of his cultivation. If this transmission channel could only be used by creatures from the demon world, he wouldn't be able to use it either.

"Stop it, old housekeeper, go try it!"

The old housekeeper didn't hesitate and strode forward, but like the old cultivator, he couldn't get even close to the picture.

This actually made Chen Lin feel relieved.

The old housekeeper can't get close either, which means that this rule and pattern restricts not identity, but other things.

"Master, let me try!"

Xiaocao volunteered.

But Chen Lin waved his hand and refused.

He stopped moving the stone slab, quickly returned to the real world, and brought Liu Shengyuan in.

"You go and try, but you just need to test whether you can get close, you don't have to enter it!"

Chen Lin reactivated the regular pattern and told Liu Shengyuan Dao.

"yes!"

Liu Shengyuan agreed, glanced at the shining regular pattern with surprised eyes, and moved forward carefully step by step.

But the ending is still the same. It doesn't mean that you can get one step closer because of your higher magic power.

Now Chen Lin was a little confused. If it wasn't cultivation factors, there were too many factors that could lead to this phenomenon.

There are many types of rule restrictions. They can limit the strength of your soul, or whether you are a boy or a girl, or even limit who can have white hair, but not black hair.

How to limit it depends entirely on how the person who created the rules and pattern set it up in the first place.

"Master, let me try!"

This time, Xiaocao didn't give Chen Lin a chance to stop him. After saying this, he ducked towards the regular pattern.

Chen Lin just stretched out his hand to stop him, but the opponent was already bounced back!

It is not restricted to men and women.

This actually made Chen Lin rule out an answer.

"The grass is useless, Master, what should I do?"

Xiaocao couldn't share the Lord's worries and looked a little frustrated.

Chen Lin shook his head and said: "It's not your fault. It seems that the person who tied the bell must be tied to untie the bell. I think that if you want to use this transmission channel, you must be someone who has activated the magic pattern."

He knew that this was the most reasonable explanation.

But in this case, it is impossible for him to find someone else to take the lead, so his subconscious does not want this to be the case.

Among the people he came into contact with, only Zi Shu could inspire Shi Ban. There was no way he would ask the other person for help. Even if the other person could agree, he would not do that.

Because if you want to maintain this rule, you must inject energy into the stone slab at all times. In other words, you must leave with the stone slab.

If the other party does not come back after leaving through this transmission channel, not only will the test result not be achieved, but no one will be able to refine the Immortal Palace and take them to the Immortal Realm.

This is equivalent to blocking all two passages leaving the Tiancang Realm.

Chen Lin glanced at the pattern, hesitated, and slowly approached with the stone slab in hand.

Sure enough, just as he expected, when he reached the distance where the previous people were bounced away, he didn't feel any obstruction.

But he only took a step forward and did not continue to move forward. After sensing the fluctuations of the regular pattern, he stopped urging the stone slab.

No matter how much he desires the unknown, he will not consider it as long as it is not desperate.

However, at this moment, a sudden change occurred!

Before Chen Lin could take back his innate power, the rules and patterns in front of him suddenly lit up, wrapping him in them!

Then the person and the Dharma pattern disappeared together!

"Owner!"

Xiaocao exclaimed, and her body shot forward, as if she wanted to catch something, but couldn't catch anything.

Liu Shengyuan and the other two people were also panicked, but after digging through the entire cave, they could not find any light or anything that could emit light.

"You three, without my instructions, are not allowed to leave here from now on. If anyone dares to step out of this cave, don't blame me for being rude!"

Seeing that Chen Lin could not be found, Xiaocao calmed down and said coldly to Liu Shengyuan and the others.

The three of them did not dare to refute, and responded in unison.

Seeing that they had no objection, Xiaocao's expression softened slightly.

Then he said to Liu Shengyuan: "You watch here. If the master returns, let the master wait for me here. I will be back soon!"

"yes!"

Liu Shengyuan respectfully accepted the order.

But Xiaocao still felt that it was not safe. With a flick of his finger, a sword energy penetrated into Liu Shengyuan's body.

Then he said: "This sword energy can only last for three days. If I don't take it back within three days, it will explode and kill you in an instant. Don't try to expel it, otherwise don't blame me if something happens!"

Liu Shengyuan looked ugly, but he could only respond in a low voice.

Xiaocao felt relieved and immediately flew out of the cave, all the way back to the node, and followed the node to the outside.

She was unable to activate the teleportation array, but fortunately she had the pass token of the defensive array. After using a puppet to create an earth escape talisman and reaching the ground, she harnessed the sword light and went straight to the Jade Cai Sect.

"What, something happened to daddy!"

Chen Ling'er was shocked when she got the news and didn't dare to tell anyone else, so she and Xiaocao returned to Taiqing Mountain.

When Liu Shengyuan saw Xiaocao coming back, he also withdrew the sword energy from his body, followed by Chen Ling'er, and he was relieved.

This lord's maid is not easy to deal with, but Sect Leader Chen is still reasonable. He, Liu Shengyuan, is the lord's confidant and cannot leak secrets, so his life will not be in danger.

The same goes for the other two.

They all signed a harsh contract with Chen Lin, and there was no condition for leaking secrets. They did not dare to say anything before, because they were afraid that this aunt, who always had a straight face, would kill them all with a sword in a rage!

"Tell me the specific situation!"

Chen Ling'er looked cold and spoke to Liu Shengyuan.

Although Xiaocao had roughly explained the situation to him midway, she still wanted to confirm it.

Liu Shengyuan did not dare to neglect, and immediately described the situation in detail, without adding any personal emotions or speculations.

Then Chen Ling'er asked the other two people, and seeing that the answers were consistent, she checked around the cave and finally returned to Xiaocao.

"What does Aunt Xiaocao think about daddy's situation?"

Xiaocao's little face was full of nervousness and worry, and she replied in a deep voice: "Wait a minute, if the master summons me to leave, it means that my life is not in danger, otherwise... bah bah bah, the master will be fine.

Damn it!"

Xiaocao hurriedly stopped mid-sentence.
