Four years, if there were still people who didn't pay much attention to being banned here at the beginning, then after four years of tossing, no one dared to underestimate here. In the past four years, five more people have died, all of whom wanted to get out of the Great Formation of the Celestial Realm outside Guò, but they were strangled inside.

With these five people as role models, the others didn't dare to act rashly until they mastered the killing array outside.

If it was just a big threat outside, it was estimated that it wouldn't make people feel nervous so quickly, after all, except for Bai Yi, who here is not an old ghost who has lived for I don't know how many years. It's only been four years, and it's really not surprising. However, it is a pity that there is still a large array of micro-growth and evolution of the Celestial Realm here, although the speed of absorbing power does not seem to be very fast for them, but after four years, most people feel that they have lost almost half of their strength.

It was only at this time that many people began to get anxious.

The fifth guy couldn't resist the pressure of the erosion of his strength, and couldn't help but rush out, but after still dying in the killing array, Bai Yi finally spoke.

"Ladies and gentlemen, would you like to exchange knowledge at this time?" Bai Yi said.

"What do you mean?" A group of people who were quietly recuperating all looked at Bai Yi.

"The knowledge texts you have obtained before, as well as the exercises and knowledge that belong to your own star field, I don't know if you have the meaning of communication." Bai Yi said.

"You guy is the most mysterious, what are you going to do?"

"Make it clear." Different voices came from all directions of the temple of knowledge. In the past four years, everyone has gone from the initial contempt, to the anxiety in the back, until the current quiet. Almost everyone chooses a place to be their retreat. Of course, there can be no real palace here, only a rough division of a territory, guarding each other. Everyone was figuring out how to get out, but it was clear that it didn't work.

"You all want to get out, but it's clear that with your current knowledge and strength, you can't get out at all. Perhaps, there will be some related things recorded in the knowledge texts left here, but since Tianxi dares to leave everyone in this place, it is estimated that it will not be enough. So, I think you might as well exchange your knowledge, perhaps, by combining the knowledge of different star fields, you can find a way from it, and then you can go out. Bai Yi said.

"It's a good calculation, if you find a way, not only can everyone go out, but you can also harvest the exercises of other star fields."

"That's not right." Bai Yi said with a smile.

"The way out can only be explored by yourself." Bai Yi said a word calmly and unabashedly.

"Hmm!" When the others heard Bai Yi say this, they immediately became very shocked, and after a while, they understood what Bai Yi meant.

This guy!

The exchange of knowledge is open, but how to get out will not be taken out, that is to say, maybe in the end everyone knows the same knowledge, but whether you can find a way to get out can only depend on yourself. Others, even if they find a way, will definitely not come up with it. And if you can't find a way to get out, even if you gain so many exercises and knowledge of the star field, you can't take it out, and you can only die here.

"Interesting, I'm in favor of this kind of exchange." A person from the Shura Star Domain said suddenly.

"I think I can, too." Another person also heard a voice of agreement.

It didn't take long for everyone to agree with Bai Yi's mention. In fact, they also understand why Bai Yi didn't bring up this mention until now. Everyone here is arrogant, and if it weren't for the fact that five people had died in four years, I'm afraid no one would want to. And now, Bai Yi's mention can not only allow them to obtain the exercises and knowledge of different star fields, but also not worry about leaks. Because, those who can't get out can't take these things with them.

As for whether they can get out on their own, there is no need to say this issue.

"Since this last friend proposed this mentions, then you might as well introduce yourself, so that you can have an understanding." The one who snatched the pendant, said Miye of the Yeno Domain.

"That's right, since we're going to exchange knowledge, how can I not introduce my identity." Immediately someone agreed. In the past four years, everyone has been wary of each other, and most of them still don't know each other's identities.

"It doesn't matter who you are, but before we do that, let's make it clear how we communicate." Bai Yi said.

"If you have any ideas, you might as well say them first." Suddenly someone said.

"I think what you are most worried about is whether the communication is fair or not, and you have come up with something very precious, but others are perfunctory with something worthless. This will undoubtedly make the so-called exchange a laughing stock, and everyone will definitely break up in the end. Fortunately, everyone here can be regarded as the top people in their respective star fields, and their knowledge is also very powerful. Therefore, when each person comes up with a knowledge, it will be judged by the remaining eleven people. It doesn't need to be exactly the same, but it needs to be about the same value. If not, then sorry, please continue to come up with something that matches the value. Bai Yi said.

"I'm okay with that." Miye of the Yeno Star Domain nodded.

"I'm okay with that."

"I would like to add that if someone wants to fill up with something of unequal value, and the result is judged by everyone to be unworthy, then not only does he need to take out something of equal value, but what he has previously taken out cannot be taken back, but is counted as free and cannot be used for chips." Banga of the Udy Domain said.

"I agree!"

"I agree."

"I would like to add that first of all people must make an oath, and all the knowledge that is exchanged here can only be memorized by oneself and not recorded in any other way. That is to say, if you can get out from here, then all the knowledge is yours, and if you can't get out, then take it to the cemetery. The master of the Shura Star Domain said grimly.

Although this guy's words are very cruel, there is no doubt that everyone has no objections, but agrees very much. Because, everyone doesn't want the things in their star field to be obtained by others like this. It's a very contradictory mentality, and I guess everyone here has the confidence to go out and be sure that they are the only winners. However, they don't want others to leave a record, in case the people trapped here can't get out, but I don't know how many years later, someone from outside comes in and gets what they left behind, and that's a big loss.

If it can't be written down in any way here, then it doesn't matter.

"It's a good idea, I like this kind of idea that people don't kill for themselves, but how can we ensure that the so-called oath is valid." Another voice came.

"If it's an oath, I have a way of making a vow here, the oath of the promise is the highest oath in the Yeno Star Field, and it pays attention to the law of words, and it cannot be changed once a promise is made, otherwise it will be subject to the laws of the universe." Miye of the Yeno Domain said.

"Does it really have this effect?"

"It does have this effect." Miye nodded.

"Whether it is effective or not, use this oath of promise as the first bargaining chip for communication, everyone can judge it." Bai Yi said.

"Yes." Miye nodded suddenly.

"No comment."

Under the mutual complementarity and perfection of the twelve people, this strange exchange of 'knowledge' between different star fields was thus determined. Obviously, this knowledge exchange relies not only on vows, but also on strategy, and how to get more with less is a question that everyone needs to think carefully. Of course, the main thing is to find a way out of all the knowledge, otherwise no matter how much you get, it will still be a failure.

"Now that the method of communication has been decided, you may wish to introduce your identity." Banjia said, looking at Bai Yi, since Bai Yi entered here, Madara was very wary of Bai Yi, and always felt that this guy was very mysterious.

Bai Yi couldn't help but smile when he saw Banjia's expression, and his body suddenly changed, recovering the appearance of a human being: "Solar System Star Field, Bai Hades Tower, Bai Yi!" ”

"Ahh

"It's you!"

"How did you end up here!" When Bai Yiyi introduced himself, the other eleven people were all very stunned. Bai Yi, this name, has been deeply imprinted in the hearts of all the high-level stars since decades ago. was tricked by Mo Mo and resurrected Bai Yi, and then it was the invasion of the Xigu Star Domain, and now the two Star Fields are in full swing, how could this supreme ruler of the White Hades Tower come to this place.

Hell yes!

"The White Emperor's actions are really beyond everyone's expectations." Miye from the Yeno Domain, who seemed a little surprised, quickly calmed down, and then introduced himself.

"I'm Yeno Domain, Shinya, Miye."

"Udi Star Field, Evil Dragon Ridge, Banga."

"Karmic Snake Star Domain, Soul Refining Abyss, Line Scales."

"Bamiya Star Field, Great Dao Boundary, Moye Dutian."

"Bucky Star Field, Starry Sky Temple, Zeus."

……

One by one, the twelve people have introduced themselves, and there is no doubt that each of them is a group of people at the apex in their respective star fields. And unexpectedly, the twelve people were all from different star fields. There were obviously people from the same star field before, but they died in the Great Array of Micro-Evolution in the Celestial Realm.

"Then, according to what I just said, I will first use the "Oath of Promise" to lead the way, you can check it." Miye took out a scroll, lifted the ban on it, and said to everyone.

After Bai Yi checked this oath of promise, he immediately evolved in the brain of knowledge. has a complete system and explanation, although it is not the exercises on the solar system star field, Bai Yi still understands it quickly. It is very mysterious, in harmony with the laws of the universe, and does have the power to restrain promises. It's just that Bai Yi didn't come out immediately, and it wasn't until a long time later, after Mo Ye Dutian of the Bamiya Star Domain moved, that Bai Yi guessed that the other party probably understood.

It wasn't until a day later, when almost everyone understood, that Miye looked at everyone.

"After realizing this, I think that the Oath of Promise does have the power to restrain promises." Bai Yi said.

"Agreed!" The others nodded as well. Each other is a person of this realm, there may be a gap, but the absolute gap is not so huge.

"Then, let each of you make a promise with the Oath of Promise, and then think of what is worth the Oath of the Promise." Bai Yi said. Maybe it was Bai Yi who proposed this suggestion, and he unknowingly became the leader.

――――――――

No one knew what effect the exchange of the twelve of them would have on the future, but now, everyone was thinking about it and fighting in the dark.
