"It's time to see what this thing is!"

Sun Chen's expression moved, his figure flashed, and he came to a palace, sitting cross-legged on a futon, holding a silver ring in his hand.

That's right, this ring is the trophy captured by Sun Chen's killing of Qi Yun, he has not had time to check it, and now he has nothing to do.

His expression moved, but there was an extra black disc in Sun Chen's hand, which was engraved with mysterious symbols, simple and unpretentious, at first glance it looked like an ordinary black stone, but when he saw the complex patterns and symbols on it, I am afraid that no one would think so.

Sun Chen tried to urge, but found that it didn't react at all, except for the hard texture, there seemed to be nothing special except for some strange symbols, but he didn't give up, he felt that this thing couldn't be so simple, there must be some secret, but he hadn't discovered it yet.

Sun Chen tried all kinds of methods one by one, and there was no response, Sun Chen shook his head a little helplessly, and then he picked up the quaint book that looked like a bit of the vicissitudes of time.

On the surface of this book, there are only a few big words scribbled "The First Solution of the Domain Gate", Sun Chen's expression was excited, he had heard of this domain gate, no, he couldn't say that he had heard of it, but it was recorded in the many inheritances he obtained, and some powers would leave this world by some means at a certain time, and one of the methods was to leave through this domain gate.

Sun Chen's expression was slightly condensed, he opened the first page and read it, and after about an hour, he finally read the book roughly and knew the general content recorded in the book.

It turns out that this book is a skill that those domain envoys must learn, or this is a profession, the name of this profession is the domain envoy, and the domain envoy is also divided into levels, which can be roughly divided into five levels, and the original owner of this book is a second-level domain envoy, he was originally a person from other worlds, but he was chased and killed by the enemy, and in desperation, he established an emergency domain gate, but he did not expect to teleport to the low-level plane of the Xianchen Continent, and what made him strange was that this seemingly very low-level plane actually had a domain gate, and it was a fourth-level domain gate, which made him hard to believe。

But none of this mattered, because what he wanted was to go home, and he didn't have any hope of going home, but when he saw this fourth-level domain gate, his heart was rekindled, because the fourth-level domain gate was already extremely powerful, and if it was not too far from his hometown, he would still have a chance to return to his hometown through this domain gate.

However, he found an embarrassing thing, that is, this domain gate actually had some damage, it was very unstable, and the teleportation was very dangerous, and it was possible that he would not go back to his hometown at all, but an unknown time and space, and there was a great possibility that he would die on the spot.

So he didn't try, but spent about five hundred years to repair this domain gate, fortunately, the damage to this domain gate is not too serious, this is the only thing that makes him feel comforted, five hundred years he has recovered a lot, but still has not fully restored it, because the level of this domain gate is too high, his ability is limited, he can only do this extent, and then he gritted his teeth and rushed into the domain gate, and then there was no response, as for whether he succeeded in returning to his hometown, it is unknown.

Sun Chen held this "Domain Gate Initial Solution" in his hand, and sighed in his heart, the world is really wonderful, and there is actually such a mysterious profession as a domain envoy, but the real domain envoy is very popular no matter where he is, because not everyone has the talent to become a domain envoy, which requires extremely high talent and super soul power.

Real domain masters can arrange domain gates at will, travel through endless time and space, almost no one can catch them, they usually go alone, and their strength may not be too high, but the escape skills are absolutely first-class, so usually no one dares to provoke the domain envoy, because you don't know when he will suddenly come out of your back and stab you.

If you provoke a powerful domain envoy, it will really be sleepless at night, and the powerful domain envoy is simply impossible to guard against.

Sun Chen had a smile on his face, this book was simply his biggest gain, if he could become a domain envoy, there was no doubt that his survivability would be greatly enhanced, and it was really the biggest thing in the world!

Then Sun Chen put his eyes on the black compass again, his eyes were bright, and he passed through this "Initial Solution of the Domain Gate" In the record, he finally knew what this compass was, it turned out that this thing was a tool for the domain envoy to establish the domain door, it could record various coordinates, and it could be directly teleported to that space in the future, and Sun Chen also saw a relatively familiar space on it, that is, the demon world, that is, the space where Li was located, this discovery suddenly surprised Sun Chen, which also made him determined to become a real domain envoy.

Not much to say, he devoted himself to this "Domain Gate Initial Solution", although this book is not very useful for a real domain envoy, but it is undoubtedly the most suitable book for a beginner, and this book cannot be said to be useless, if you eat it all thoroughly, you can at least become a second-level domain envoy, don't be surprised, this is because there are too few talents in the domain envoy industry, and there are almost no more in one world, like the Xianchen Continent, Sun Chen estimates that most of them may not even know what the domain envoy is.

This also means that it is very difficult to become a domain envoy, so the cultivation world doesn't care about the establishment of knowledge cheats such as domain gates at all, because there are few people who can understand them, and even if they can understand them, there are almost no ones who can cultivate, so this kind of domain gate cheats that seem to be extremely valuable are very cheap, and in some big worlds, they are almost a stall.

Ignoring the things outside the window, Sun Chen fell into the middle of participating in research, he didn't care about anything, and while cultivating, he studied this book "The First Solution of the Domain Gate!"
