As for Yan Feng's words, he wants to teach several times in the sky, so as to obtain merit points and improve his own strength, and the place, Yan Feng also thought about it, so he used his own city air conditioner, and the city air conditioner itself is similar to a small space.

With his own strength, there is no difficulty in hiding that space in the sky, and when the time comes, a few more formations will be arranged to make the city air conditioner even more mysterious.

Of course, Yan Feng also needs to arrange an inspiration array inside the city air conditioner, and only when one of the array paths, instrument paths, rune paths, or array roads reaches the prefecture level, can he come to Yan Feng's city air conditioner to listen to the class, and Long Chengfeng heard Yan Feng's words, and said: "Okay, I will publicize it as soon as possible, and you have to prepare early." ”

Yan Feng listened and said, "Okay." ”

Immediately, Yan Feng ended the communication with Long Chengfeng, and then said: "I still have some things to do, go out first, there is anything I don't understand in terms of exercises, Yaoyao and they are all people who have practiced once, and they should be able to explain." ”

After Yan Feng finished speaking, he disappeared directly, and a moment later, Yan Feng appeared in the air at an altitude of 100,000 meters, and then he directly took out the city air conditioner from his lottery space, and then, Yan Feng also began to arrange it in the void.

After a while, the city air conditioner was hidden, and from the outside, there was no longer a trace of change, and then, Yan Feng arranged a teleportation array, and then, Yan Feng himself, entered the city air conditioner, and then began to arrange the induction array.

Soon, the induction formation was arranged, and at the same time, the people of the entire Northern Region also knew that the Four Dao Sages were ready to be taught once, and the Four Dao Sages were talented enough to become the Four Dao Sages at such a young age, their talents were terrifying, and their understanding of each Dao might be stronger than the previous Sages.

Therefore, everyone was very happy to be able to listen to Yan Feng teach his experience and understanding of the four realms, so countless people sensed the summons from the four realms of saints, and the people of each realm level or higher also sensed the location of the city's air conditioning, and then flew towards the direction of the sky.

And Yan Feng was also waiting inside the air conditioner in the city at the moment, and after about twenty minutes, the first group of people arrived, this group of people were fifteen god-level masters, two of them were Xiao Dan Wang and Xiao Dan Huang, and now that the new Dan Dao Sage is alive, the original people of all the Dao who have potential have also forced out the last potential.

Therefore, the original Xiao Dan King and Xiao Dan Huang have now become god-level alchemists, and although Yan Feng and Xiao Dan King have had conflicts, after all, the other party has also contributed their own materials for the Heavenly Scale, and the gap between the two is too big at this moment, and Yan Feng can't afford to take revenge at all.

And these fifteen god-level masters also sat at the front, and they didn't dare to say more, waiting for the arrival of others, and after another half an hour, finally, the heaven-level masters also arrived, and the heaven-level people were much more than the god-level masters, and there were more than one hundred and thirty people in the entire Northern Regions.

After another half an hour, the earth-level masters finally arrived slowly, the number of earth-level masters was more than two thousand, and Yan Feng's face also showed a trace of satisfaction, the stronger the comprehension of the people who listened to him to teach the knowledge of the various paths, and the greater the number of people, the greater the merit value that Yan Feng obtained.

With so many people nowadays, I guess I can get a lot of merit points, right? Thinking about it, Yan Feng slowly started to speak, because it involved different aspects, and the people who listened to Yan Feng's explanation had different cultivations, so Yan Feng also started from a low level, and this time, Yan Feng mainly talked about the knowledge of the masters of the prefecture level.

Of course, because Yan Feng will also preach a lot of things like ground-level pills and runes that were not originally available in the Northern Regions, it is also of great help to god-level alchemists or heaven-level alchemists, and first of all, it is the ground-level Danfa.

When Yan Feng finished explaining all the ground-level Dan Methods, the voice of the Panda Dragon sounded in his ears: "Teach the Earth-level Dan Method, and get merit worth 10,000 points." ”

10,000 merit points, this is already very high, and next, it is the ground-level instrument path, this time, Yan Feng also obtained 10,000 merit points, and then the ground-level rune and the ground-level formation, after the four explanations, Yan Feng also got a full 40,000 merit points.

And everyone is slowly digesting and understanding at the moment, Yan Feng saw that everyone listened to it one by one and continued to speak, I am afraid that there will be no effect, so Yan Feng said: "You go back first and understand it well, wait until the Four Dao Palaces are opened again, and then come to listen to the class." ”

Hearing Yan Feng's words, everyone thanked them and said, "Thank you to the Four Sages." ”

Then, everyone retreated one by one, and Yan Feng also said silently in his heart: "Enter the lottery space!" ”

As soon as the words fell, Yan Feng appeared in the vast lottery space, and then, Yan Feng said directly: "Exchange the eighth level of the Lich Slayer Secret Technique!" ”

As soon as the words fell, a dazzling sun immediately appeared around Yan Feng's body, surrounding him entirely, and then, the powerful spiritual power contained in this sun was also continuously injected into Yan Feng's body.

And Yan Feng's originally quite terrifying momentum was also rising one by one, and by the time this sun was completely absorbed into Yan Feng's body, the momentum on Yan Feng's body was already stronger than that of Zi Yao Shenzi after using the increase of the Shun Rebellion God and Demon Array, that is to say, Yan Feng's current strength was close to that of the powerhouse of the Void God Realm!

Redeeming the eighth level of the Lich Slayer Technique, Yan Feng consumed 32,000 karmic points, so Yan Feng's available karma points were only more than 8,000 points, merit value: 48312/76323, karma value: 0/67894, and then, Yan Feng also carefully sensed the various forces in his body.

And the most important thing is that what he experienced was the power of time and space in his body, Yan Feng obtained the rebirth pill against the sky, and originally wanted to resurrect his grandfather.

However, after analyzing the materials and medicinal effects of the Anti-Heaven Rebirth Pill, Yan Feng found that although the effect of this Anti-Heaven Rebirth Pill is extremely anti-heaven, at least, it needs to have a complete physical body, Grandpa's body has already decomposed, where did he come from?

Therefore, Yan Feng must improve his strength again, and wait until he can do time flow or time reversal on objects in a certain time range, and this one or two seconds or one or two minutes is more than a year.
