After returning to the phoenix tribe's headquarters in the Demon City, Feng Hongyuan arranged the affairs of the clan and prepared to go into seclusion and break through the forbidden spell directly. I don't know how long it will take him to break through. It may only take a few days or several months. However, after experiencing the strengthening of the previous heavenly race, he felt the essence of the strongest fire at close range. His grasp of breaking through the fire-type forbidden spell was almost 70%, which is already an extremely high probability.

In fact, it may only take three or four days to truly break through the forbidden spell, but before that, you need to adjust yourself to a perfect state and look for opportunities to break through, which may take half a month or even several months.

As for how to deal with the earth fire stamen required for breakthrough, it is not simple. In some previous experiments, Mu Bai found that he had absolute control over the system space. In it, he was as omnipotent as a god. It is naturally not difficult to remove the core of the earth fire stamen. He even completely preserved the part of the earth fire stamen, and he could completely convert the remaining part into fire element energy to promote his breakthrough in the fire system.

Mu Bai's ultimate fire, the savings needed to break through the realm barrier are beyond imagination by others, but with the power of fire element outside this earth stamen, at least the energy required to break through the middle level is absolutely enough. Maybe even breaking through the high level is enough. After all, this is a forbidden spell treasure, even if it is only a small part of it, it is extremely huge for middle level and high-level mages.

However, before Feng Hongyuan was in seclusion, he also brought Mu Bai, Feng Shaokai, Feng Minhao, Feng Shaohe to the cultivation tower of the Phoenix Clan in the Demon City. It was an ancient building made of red stone bricks. Countless mysterious inscriptions were carved on the exterior walls, forming magic circles, gathering the surrounding elemental energy.

An ancient and profound breath came to my face.

Pointing at the cultivation tower, Feng Hongyuan introduced to Mu Bai,

"Young master, this is the cultivation tower. It was built hundreds of years ago by the Phoenix Clan. Cultivating in it can greatly increase the speed of cultivation.

There are four levels in this cultivation tower. The element concentration of the first layer is 25 times that of the outside world, the second layer is 50 times that of the outside world, the third layer is 100 times that of the outside world, and the fourth layer is even more incredible 150 times.

Of course, if you want to practice in the cultivation tower, you need to consume magic energy to withstand the pressure from the surrounding areas. If you force yourself to practice at a higher level, it will only consume all the magic energy in your body, dissipate your mental power, and you will not be able to concentrate on the meditative cultivation.

However, the cultivation bonus effect in the cultivation tower will gradually decrease over time.

The third floor under the cultivation tower will last for a total of seven days, and the fourth floor is my retreat.

You have gained a lot from this experience in Lanyang City. I believe that you can make a breakthrough in this journey to the cultivation tower. I wish you good luck."

Everyone did not refuse. They really needed a good environment to stabilize their gains and make breakthroughs, especially Feng Shaokai. His eyes were firm. This time, it should be his opportunity to break through to the third level of the fire-type super level. Only in this way can he keep up with the pace of the young master's rapid improvement.

"Young Master, patriarch, please come with me."

Feng Xingchen (fire-level super-level third level, thunder-level, earth-level super-level third level, space-level third level) who guarded the cultivation tower bowed slightly to Mu Bai and Feng Hongyuan and made a gesture of invitation.

Mu Bai nodded and said with a little excitement.

"Let's go!"

After entering the cultivation tower, what caught my eye was a long corridor. The dark red patterns on the walls on both sides emitted a dim red light after Mu Bai and the others entered, bringing some light.

After walking about a few hundred meters in a low light environment, stairs appeared in front of them, and at the end of the stairs, light came, like a beacon in the dark night, guiding the direction.

"Young Master, patriarch, I won't bother you."

"Well, you go out first. During my retreat, everything in the clan depends on you."

Feng Shaokai patted Feng Xingchen on the shoulder and said.

"Don't worry! Clan leader, you just need to do your best to break through the final barrier, and just leave the rest to us!"

After saying that, he stepped out.

When he walked up the ladder, Mu Bai clearly felt a faint invisible pressure oppressing his spirit, and this pressure was slowly consuming his magic energy as Feng Hongyuan said, but this was just a ladder to the first level. Besides, Mu Bai had five systems in total, so this little magic energy was not consumed much.

After walking through the steps, everyone felt that the space suddenly became clear, as if they had entered a new world. A huge bright space appeared in front of them, and at that end, there was a staircase leading to the second floor.

After coming to the first floor space, Mu Bai clearly felt that the concentration of elements around him was much higher than that of the outside world, and it seemed that because most people in the Phoenix clan awakened the fire system, the fire system with the highest concentration of elements in the cultivation tower was also the fire system. Under his perception, the concentration of elements around the fire system was much higher than that of other elements, especially the concentration of water element, which was even nearly 1 times higher.

Here, even if Mu Bai did not take the initiative to practice, he felt the endless elemental energy around him drilling into his body. His cultivation was increasing at a speed visible to the naked eye. Here, it was still the first level of space. It was hard to imagine what kind of cultivation speed he could obtain on the second level and the third level. I just don’t know which level of cultivation he can withstand the pressure at most with his current cultivation level.

Moreover, due to the system, Mu Bai's cultivation speed itself has a four-fold bonus. If the element concentration is included, Mu Bai's cultivation speed can reach 100 times on the first level. That is to say, practicing here for 1 day is equivalent to practicing outside for 100 days. What a terrifying cultivation speed.

Of course, the real cultivation speed cannot be calculated like this. In the first few days of the beginning, the cultivation speed did soar. However, this kind of thing is a bit like taking medicine. Taking too much medicine can easily produce certain antibodies, and the body and spiritual world will also be saturated and cannot accommodate more elemental power, which will lead to the reduction of the absorption efficiency of elements over time.

Buildings that assist in cultivation such as the cultivation tower must have the best effect for the first time, and the effect will be greatly reduced in the next few times.

Without stopping on the first floor, the group stepped onto the second floor and walked up to the steps. The surrounding mental gravity was much greater than when it was on the first floor. Even Mu Bai felt a little pressure, and the magic energy in his body was constantly consuming, but it was still acceptable.
