In the end, if the Poison Prince had not sacrificed his life with his trump card, he, Xiao Xiangzi and others might not have been able to escape unscathed.

This wonderful mountain is also very different from the last time. Various crises are more difficult to survive than before. Now it is only halfway up the mountain, and there is no way to face the dense clouds in front of you.

It can absorb magic and attack with medium-grade magic weapons, and the magic weapons will be corroded. So he knows very well that if he breaks through, he may be corroded and will die without a complete corpse.

And he remembered that there was no such clouds at the beginning, but now it appeared here, which made him feel surprised.

Besides, Chen Rui walked out hundreds of feet and arrived at a stone pavilion. Without any surprise, this was another level, and the concerns were set up again.

If this question is explained in the way of the previous life, it means giving four different numbers to find one of the numbers that can be squared.

This is a huge number. Although he was a math teacher in his previous life, he could not be able to calculate it in a short time.

Fortunately, he is a math teacher after all. After some hard calculations, he finally found the correct answer.

Along the way, Chen Rui had walked through eight similar stone pavilions, each of which was a math problem.

Chen Rui showed excitement in his eyes. Although these arithmetic questions were somewhat difficult for people in this world, they were not very difficult for him. He believed that as long as there was a magic problem in every stone pavilion on the road ahead, he could pass it safely. If he kept persisting, it was not impossible to survive this so-called no return path.

Moreover, if Chen Rui's purpose of solving the problem was to survive and overcome difficulties at the beginning, then now he has another purpose. The more he studies it, the more he can interest him. Because he has already vaguely realized that these arithmetic problems are related to a certain amazing restriction. If he can integrate this calculation into the restriction and finally master the restriction that is faintly exposed at the tip of the iceberg, then he will gain a very powerful force.

There is no time in the mountains, and the cold is gone without knowing the years. In a blink of an eye, eight years have passed. On this day, Chen Rui stood in front of a pavilion on the side of the mountain. He took out a few pills and swallowed them. At this moment, a few of his head had turned white.

Just because he was busy and fond of food and sleep, he solved the math problems at all costs. As he continued to solve the problems, he could understand the restrictions on both sides of the road. Later, he was not satisfied with solving the math problems, but studied the restrictions next to the path. This study left his mind in calculations every moment. Even a few of his head turned white.

He suddenly felt that there was a saying in his previous life that mental labor is sometimes more exhausting than physical labor.

With his research, his spiritual consciousness has been strengthened through continuous research, and even his cultivation has been loosened unknowingly. As long as he is given a safe place to retreat and have enough spiritual power to impact, he can form a pill.

His eyes were even sharper, and his whole temperament was completely different from before. If Chen Rui eight years ago was a sharp sword unsheathed, it made people feel like he was retreating. Then, in addition to these, there was another unfathomable feeling.

This feeling comes from his eyes, which seem to be all-encompassing, and even clouds float by. If the Demon King of Extreme Desire sees Chen Rui again, he will definitely not be able to imagine his own eyes. This is clearly the look that he will have after achieving certain attainments in the way of prohibitions and calculating.

Chen Rui's eyes were cultivated. Within the past eight years, he integrated the mathematical calculation methods he learned in his previous life into the restriction method in this life, which improved his delayed calculation ability by several levels.

This kind of progress was something he had never thought of. Fortunately, the arithmetic problems in the stone pavilion on the mountain road and the forbidden group on the roadside gave him an opportunity.

In the past eight years, he has solved countless arithmetic problems, and has also studied many restrictions on the mountain. The restrictions here are very powerful and complex. Each restrictions require a lot of time and mind. After careful study and thinking, he almost buried them in many of them.

Especially with some restrictions, they came very abruptly. If Chen Rui had not thought of the previous arithmetic problems, he would have died long ago without a place to bury him.

Chen Rui calmed down and walked in the mountains. In the past eight years, every time he lifted a roadside ban, he would definitely try to arrange it. However, it is easy to lift the ban and difficult to lay it out. In the past eight years, he only learned one ban. He named it the Lotus Nine Forbidden.

The first magical problem he encountered was related to the Nine-Class. After that, he then contacted all the magical problems, and finally combined with the restrictions on both sides of the path he broke, he finally realized it.

This kind of restriction is similar to the binding technique. Once you get hit, your whole body cannot move, and even your spiritual power and consciousness cannot be dispersed. It is very domineering.

From then on, every time he walked past a stone pavilion, he would set up the Nine Lotus Forbiddens in the pavilion. In this way, if a later generation entered the stone pavilion to solve the problem, he would first untie his Nine Plum Blossom Forbiddens. In this way, even if he could solve the problem with his strong cultivation, he would waste a lot of time.

If the later generation cannot solve the magic problem in a very short time, then once the purple fire burns, he will die without a place to bury him.

In eight years, Chen Rui changed a lot, especially in terms of bans, which opened his horizons and broadened his horizons. Now if he returns to the ban mountain of Yujiefei, he is confident that he can pass.

Chen Rui studied and arranged bans along the way. Before he knew it, his Nine Lotus Forbiddens had made a big breakthrough. In his own words, it was no longer the Nine Lotus Forbiddens, but the Eighteen Lotus Forbiddens.

At the same time, at the entrance of the vortex at the foot of this wonderful mountain, two people walked out, the two of them were the Demon Lord of the Extreme Desire and Hongyun.

Although the two of them looked as normal, they were in an extremely embarrassing manner. In the castle in the loess, they tried their best to do all their cards and spent a lot of effort. Finally, they had a stalemate with the corpses for several days before rushing out of the castle.

When they rushed out of the castle, both of them were seriously injured. In desperation, they could only find a secluded place in the loess territory to heal their wounds.

Unexpectedly, the injury was not healed and was besieged by a large group of corpses. In the end, they experienced a lifetime of death and consumed countless magic weapons and pills. Among them, hundreds of corpses were killed by them, and the average corpses were killed by them.

If it weren't for the last moment that the Demon Lord Jiyu exploded one of the life-saving magic weapons, the two of them would have been torn apart by the huge corpse and died on the spot.

After going through all kinds of difficulties, the two finally arrived at the fairyland before the road to no return and were able to heal their wounds.
