Mu Feng directly entered the ninth floor of Wuji Immortal Palace to practice at a hundred times the time flow rate.

After five months outside, I can practice for forty-one years in the Wuji Immortal Palace. After such a long time, not to mention reaching the eighth-level ninth-level formation master, the sixth-level seventh-level formation master can always reach it, right?

"Well, I don't want to have that much time. I'll just raise the seal first."

Then Mu Feng was immersed in the formation cultivation mark left by Elder Inorganic.

After reading it a few times, Mu Feng began to officially enter the practice.

Mu Feng's hand pinching magic tricks, and a series of colorful Eight Trigrams diagrams appeared in the void. After dozens of breaths, the colorful magic seals in the void reached more than four hundred. The growth rate of the magic seal was reduced instantly, and one could be increased by dozens of breaths.

However, one more Dharma seal will disappear on the other side. Mu Feng can only maintain more than four hundred Dharma seals for a hundred breaths. After a hundred breaths, the Dharma seal will dissipate.

No matter how hard Mu Feng tried, he could only maintain more than 400 magic seals, and it could not be increased without decreasing. The speed of the growth magic seal was relatively the same as the dissipation speed.

In just a few hours, Mu Feng was already sweating profusely and his face was flushed, and he obviously was under a lot of pressure.

The control of the magic seal not only requires strong spiritual power, but also strong mental power.

The main reason why there are few formation masters in the cultivation world is that most monks have poor mental power, cannot control the condensation of magic seals, and cannot even condense their mental power.

Mental power is similar to thoughts, but it is different. Thoughts come from thoughts, while mental power comes from soul space. The two cannot be compared at all.

Even when many high-level formation masters set up formations, they will have insufficient mental power, so they must use external forces, such as magic weapons, elixirs, or soul stones that bless their souls.

Mu Feng gritted his teeth, endured the severe pain from his soul, and constantly controlled the condensation of magic seals one by one.

A few days later, Mu Feng had to stop because the same thing has been the same in the past few days. The amount of condensation of the magic seal has been around more than 400 paths, and it is not enough to make progress. No matter how hard he tries, the result is still the same.

Perhaps it was because Mu Feng's path to practicing Taoism was too flat, and he could not make it in just a few days, which made Mu Feng feel a little depressed and sad.

"Is my formation talent only more than 400 magic seals? Even the level of a second-level formation master cannot be reached?" Mu Feng asked himself.

Then Mu Feng looked at Elder Inorganic's formation practice techniques again carefully. A day later, Mu Feng finally saw the keywords.

The key to practicing formation is the ability to control the Dharma seal, and the ability to control the Dharma seal depends on the strength of the mental power.

"So, if you want to increase the number of Dharma seals, you must first strengthen your mental power?"

Mental power is also soul power. Fortunately, Elder Inorganic’s formation cultivation techniques also have mental power cultivation methods, but it is said that it takes an extremely long time.

If it were in the past, if it took a long time to practice mental power, Mu Feng might have given up, but now, Mu Feng has the Wuji Immortal Palace, and what he lacks the least is time.

"Well? Can the soul refining grass speed up the improvement of mental power?" Seeing the mention in the magic formula, Mu Feng then searched in the nine-level fairy palace spiritual grass according to the description of the soul refining grass in the formation practice formula.

Wuji Immortal Palace has recognized Mu Feng as the master, and it is much more convenient to find. With just one thought, Mu Feng accurately found the location where the soul refining grass grows. In one corner of the Nine-level Immortal Palace, a large area of ​​soul refining grass really grows.

There are soul refining grasses of all ages, and all spiritual herbs can advance like cultivators. With the time and the intensity of spiritual energy, many spiritual herbs can also be advanced to heaven-level spiritual herbs.

The lowest soul refining grass on the ninth floor of Wuji Immortal Palace is decades old. The dozens of soul refining grasses in the middle are extremely tall, emitting extremely powerful fluctuations of mental power. It is estimated that they have grown for at least ten thousand years, and they are heaven-level spiritual herbs.

"Hahaha, God really helps me. With so many human, earth, and heavenly soul refining grass, why worry about not being able to increase my mental power?"

Spiritual herbs are spiritual and resist Mu Feng’s instinctively picking. However, they grow in the Wuji Immortal Palace, so all resistance is futile.

Mu Feng picked some human-level soul refining grass and began to practice mental power.

I saw Mu Feng sitting in the ninth-level fairy palace, hundreds of human-level soul refining grasses floating around Mu Feng, and the colorful spiritual energy spreads with Mu Feng as the center, covering hundreds of soul refining grasses.

Suddenly, the black aura in the soul refining grass surrounds Mu Feng like a tide. Mu Feng refused everyone and sucked them all into the soul space. His mental power was growing rapidly at a speed visible to the naked eye.

The mental power extracted from the soul refining grass stimulated Mu Feng's soul. As the mental power continued to pour in, Mu Feng's soul began to feel a little unbearable, and severe pain arose.

Sweat as big as beans kept flowing down from his forehead, and Mu Feng's whole body was already wet with sweat.

Mu Feng gritted his teeth, and a trace of blood overflowed from the corner of his mouth and even began to tremble. It is conceivable how much pain Mu Feng suffered.

But Mu Feng did not give up. If he could get through, he would be flat. If he couldn't get through, he might be scattered.

The biting pain almost made Mu Feng faint. At this critical moment, the colorful Nascent Soul in the Dantian suddenly opened his eyes, waved his hand, and a colorful divine light rushed straight into the soul space.

Suddenly, Mu Feng's pain decreased sharply, and he relieved the pain a little, and Mu Feng began to increase his efforts to absorb mental power.

A few days later, hundreds of soul-refining grass withered and had been absorbed completely. At this time, Mu Feng's soul space had expanded countless times, like a large room of dozens of square meters, filled with extremely powerful mental power.

Mu Feng did not dare to be negligent, and then picked dozens of earth-level soul-refining grass again and prepared to refine it again.

At first, Mu Feng did not dare to refine it together, so as not to instantly collapse the soul space with his powerful mental power, so he slowly refines it one by one.

The earth-level soul refining grass is indeed much stronger than the mental power contained in the human-level soul refining grass, and it is more pure. It is estimated that the mental power contained in a earth-level soul refining grass can be at least comparable to hundreds of human-level soul refining grass.

As Mu Feng's soul space expands, the mental power that can bear is gradually increasing.

Day after day, five years have passed in the Wuji Immortal Palace before I knew it, and just over twenty days have passed from outside. On that day, Mu Feng opened his eyes, his face was full of smiles, and he opened his hands and stretched.

At this time, Mu Feng’s soul space can be said to be boundless, like endless starry sky, with no limits, and extremely strong spiritual power wandering in the soul space.

Seeing that the withered human-level, earth-level and heaven-level soul-refining grass were covered with at least tens of thousands of trees, Mu Feng couldn't help but feel ache. If the soul-refining grass had not been consumed almost all, Mu Feng might have continued to refine it.

If so many soul-refining grasses were not the same as others, at least hundreds of formation masters could be cultivated. Each soul-refining grass is extremely precious and basically belongs to the kind of existence that has no market value.

However, Mu Feng was almost squandered. There were less than a hundred soul refining grass left in Wuji Immortal Palace, and they were all low-grade human-grade soul refining grasses of low age.

Fortunately, Mu Feng's soul space is already extremely large, otherwise he would have cried to death if he thought about it.

"Hehe, I will start practicing the magic seal next. This time it will be a natural thing, right?" Mu Feng said to himself.
