After confirming that his sister's life was safe for the time being, Mu Fan's worries in his heart could finally be alleviated a little.

But instead of being relaxed, time has become more of a problem for him.

Now I don't have to worry about the threat in my body, but my sister's life will be in danger again at some point.

Mu Fan knew that he was not even as strong as one billionth of his previous life, and he couldn't control the methods of the God Emperor in his memory.

So after refining a elixir to alleviate injuries for Su Mengqing, he went headlong into the prison tower and began refining the Xuandan in a race against time.

In the prison tower, Mu Fan does not need to avoid the eyes of outsiders, and can give full play to his strength.

And the Hell Tower is a thing of the Upper Realm, and the aura contained in the tower is many times stronger than the Lingxiao Continent where the Tianyue Country is located.

In order to cultivate the "Prison Suppression Floating Slaughter Technique", the person who created the Hell Town Tower specially cultivated a special practice room in the Hell Town, and used evil qi to urge the operation of the practice room, which could increase the cultivation speed by three times.

According to the Heavenly Dao Pen, the cultivation speed of the upper level of the practice room was faster, but it had not dared to step into the room above the second floor for so many years, so it didn't know what was going on above.

In its own words, it is afraid of being detected by the laws of this realm, so it does not dare to use its power often, even in the prison tower.

And the three-fold speed in the tower is already very fast compared to the outside world, but for Mu Fan, this cultivation speed is still too slow.

Not only is he in a hurry to save his sister, but he is eager to recover all the strength of his previous life in one go.

The more realistic reason was that the tumor formed by the fourth level in his body was competing with it for cultivation resources.

After the three times the cultivation speed was offset by the tumor, there was basically not much effect left.

If you want to improve your strength quickly, you still have to rely on pills.

He took out six big tripods from the town prison tower, stacked them in the formation of the third, second, and first, and set up a "small three-talent array" to assist in alchemy.

The next three are the tripods, the middle two are the earth tripods, the upper one is the sky tripods, and the six tripods are rigid and soft and mutually beneficial, yin and yang are mixed.

The vitality between the tripods is interconnected, as if forming a small world with a closed cycle, and Mu Fan can refine the pill by himself without Mu Fan's real-time care.

With the assistance of this array, Mu Fan directly threw all the mystical medicines into the six tripods, and took out 10 million spirit stones as the energy to drive the formation.

After he finished refining all the materials, the remaining boring alchemy part was left to the formation to complete by itself.

During this period, he devoted himself to cultivating the "Prison Suppression Floating Tu Technique", striving to cultivate this set of exercises to a higher level before the Holy Land Inheritance opened.

Although this set of exercises is not as good as the secret skills of the divine skills in his memory, it is the set of exercises that is most in line with the current situation.

"The Recipe for Suppressing Prison and Floating Slaughter" is not only a technique, but also a martial art.

In terms of exercises, it is naturally a cultivation method that absorbs evil qi and turns it into one's own use, while martial arts are divided into nine moves.

They are the divine ape, the treasure elephant, the Xuanwu, the Vermilion Bird, the green dragon, the white tiger, the unicorn, the heavenly phoenix, the true dragon, a total of ninefold, so it is also called the ninefold floating slaughter.

Mu Fan only used the first "Divine Ape Floating Slaughter" to be able to compete with the Xuanwu Realm, if he mastered a few more Floating Slaughter, wouldn't there be no opponent in the Tianyue Kingdom?

It's just that the evil qi on the first layer of the Hell Tower has been completely absorbed by him, and if he wants to increase the power of this move, he has to use the evil qi of the second layer.

The second-layer suppressed Heavenly Martial Realm monsters were existences that he was not even qualified to mention in his previous life, and at this moment, he had to deal with them solemnly.

Before taking Xuandan to improve his strength, he didn't plan to make useless attempts.

Ten days passed in the blink of an eye, and at the staircase leading to the upper floor of the prison tower, from time to time there was a sound of the earth shaking like a mountain.

Whenever the loud noise passed, you could see a teenager with blood in the corner of his mouth flying upside down from the upper floor, falling dozens of meters in embarrassment.

If he was lucky, he just spit out a mouthful of blood, and he didn't care to wipe the blood off his mouth and continued to rush towards the second floor.

If you are unlucky and encounter a monster going crazy, even if you push the Nine Turns Golden Body Technique to the extreme, you will still be beaten to the point that your head will be broken and your bones will be broken.

Fortunately, he has already finished refining the Xuandan, no matter how many injuries he suffers, as long as he still has a breath, then a superb "Returning Life Pill" will be in his stomach, and the injury will be healed immediately.

Mu Fan relied on the recovery effect of the best Xuandan's elixir, and stubbornly carried the crazy attacks of the Tianwu Realm monsters, and rushed to the second floor of the Hell Tower again and again.

When he was injured, he took healing medicine, and the surging vitality in his body slowed down, so he took out the Xuandan and poured it into his mouth as if it were peanuts.

This retreat is a frenzied retreat that takes place day and night, without respite.

Every time I stepped on the second floor, I was immediately blown away, and this seemingly one-sided passive beating didn't seem to be able to achieve any results at all.

But Mu Fan was not beaten in vain, every time he was blown away, he would pick up a handful of the unique Heavenly Martial Realm evil qi of the two-story building.

Even if the time spent on the second floor was only for a moment, the two dantians could be fully opened and sucked in, and they could harvest a lot of evil qi in just a moment.

The strength of the Heavenly Martial Realm monsters suppressed in the tower had already been suppressed by the formation, and although their attacks could hurt Mu Fan, they could not kill him.

It was indeed painful when he was beaten, but the Nine Turns Golden Body Technique also became more powerful under the continuous attacks of the Heavenly Martial Realm.

As his physique became stronger, the time he spent on the second floor gradually increased from one breath to one breath and two breaths, until he was finally able to resist the Heavenly Martial Realm monster with one move.

During this period, he was blown away I don't know how many thousands of times, and every time he fell, he immediately got up and rushed again.

Under his indomitable persistence, the "Prison Relief Technique" finally broke through the second treasure elephant Floating Slaughter, and the "Nine Turns Golden Body Technique" was also successfully cultivated to the fourth level.

As for the realm, under his exaggerated practice of eating Xuandan as a peanut, he successfully ascended from the fifth level of the Spirit Movement Realm to the first level of the Spirit Martial Realm.

In just a few months, he has been promoted from the Spirit Movement Realm to the Spirit Martial Realm, and if outsiders know about it, they will definitely give him a thumbs up and praise him.

But Mu Fan was very unhappy with this, he was afraid that he had taken thousands of Xuanwu Pills in the past few months, and any Xuanwu Realm master with good qualifications would be able to break through the Tianwu Realm.

And he actually broke through from the Spirit Realm to the Spirit Martial Realm, and his efficiency was not slow.

But the Heavenly Demon Body is such a perverted and tormented physique, and there is no barrier to restrict the growth of the realm, but the tumor in the body has become a headache.

If it weren't for Mu Fan's mastery of the "Creation Dandi Formula" that could easily refine the medicinal properties of the pill, allowing him to take the pill frantically ignoring the side effects, I'm afraid he wouldn't even be able to break through the Spirit Martial Realm.

Time flies, calculate the time, and the Holy Land Inheritance Trial is about to begin.

Mu Fan picked up his cultivation movements, crossed his knees and exhaled for a long time, and only after his breath stabilized did he open the gate of the Prison Tower and turned into a ball of spiritual light and drilled out......
