After cultivating the seventh-level magic of the thunder and lightning system, Luo Lin couldn't help but breathe a sigh of relief, so far, he has completed several cultivation projects that are 'small investment and quick results', since there is still time in the future, then he is a cultivation project that takes a long time to cultivate.

Elixir alchemy, which is Rollin's first choice.

After some experiments, Luo Lin was pleasantly surprised to find that the cultivation of potion alchemy could also be accelerated in the colorful secret room!

This couldn't help but make the heart hanging high in Luo Lin's heart let go, and with a sevenfold acceleration, then, even the cultivation of the potion alchemy, which was extremely time-consuming and labor-intensive, became much easier!

Although Luo Lin also had some predictions about this point before, he couldn't be relieved if he didn't see with his own eyes that he could really accelerate the cultivation of potion alchemy, after all, on the Aragorn continent, except for the master of Constro who was outside the Divine Journey Heaven, the highest potion alchemy was only a seven-star intermediate.

They have cultivated for dozens of years, and they have not reached the level of seven-star high-grade potion alchemy for hundreds of years, although Luo Lin is a veritable peerless genius praised by Mitheus in medicine alchemy, but Luo Lin himself cannot be sure that he can cultivate his own potion alchemy beyond them in such a short period of time.

However, now that he had personally verified that the Martial God Tower's Seven-Colored Secret Room could increase the cultivation speed of his potion alchemy by seven times, Luo Lin couldn't help but be overjoyed, in this way, he was almost certain that in the three years before Xiao Huo-Ke's life came to an end, his potion alchemy could reach the seven-star advanced level!

The overjoyed Luo Lin was about to continue to practice the potion alchemy when suddenly, his eyes flashed, and his figure disappeared into the colorful secret room.

"Buzz ......"

When Luo Lin came out of the colorful secret room of the Martial God Tower, he felt a strong spatial fluctuation, in the cave, the donkey who had been lying there and sleeping bored had already been awakened by this fluctuation, and at this moment its two long ears were erected forward, and a pair of big eyes were vigilantly watching the colored air flow in front of it.

When Luo Lin appeared, the donkey Xiao Hei breathed a sigh of relief, stepped out of his four hooves, and came to Luo Lin's side.

"Buzz ......"

At this moment, more violent spatial fluctuations were transmitted, so that Xiao Hei couldn't help but summon his extremely defensive colored light mask.

In this regard, Luo Lin did not have the slightest defense, because although this fluctuation was powerful, it could not hurt him in the slightest.

It turned out that the source of this fluctuation was the space seed that came from the mushroom cloud-like colored air flow, oh no, it can't be called a space seed anymore.

Because in Luo Lin's sight, there was a small palm-sized tree as black as ink in the colored air current, exuding a terrifying fluctuation that made people palpitate.

"Space Tree! Hiss, I didn't expect the space energy to grow to such a state in such a short period of time!"

Luo Lin couldn't help but gasp, he was no stranger to the small tree in front of him, which was as black as ink, and there was a detailed record in the Mitheus space notes, and the spatial energy had several forms in the process of growth.

The first form is the initial state, which is the form as thin as a hair.

The second form is the form after the spatial energy condenses into the space seed, which is the form that is like a black sesame seed.

The next third form is the form of space seed growth, which is manifested as a series of states such as seed germination, growth, rooting, etc., it is worth saying that this state lasts for an extremely long time, and under normal circumstances, it definitely takes dozens or even hundreds of years to complete, but after the previous small black eggshell, and later this colorful air flow, it actually makes the space energy in just ten days is to complete the form that can only be completed by tens or even hundreds of years.

This couldn't help but surprise Rollin!

Now, the space energy in front of him has entered the fourth form - the form of the space tree!

Reaching the form of the space tree, the space energy is to grow into the final form, as for the subsequent cultivation, it is the process of the space tree absorbing the space energy between heaven and earth and gradually growing, this process is an almost endless process, according to the notes of Mitheus, with the continuous growth of the space tree, it will gradually bring some very powerful space attribute blessings to its owner.

Luo Lin didn't expect that just after a short period of half a month, the colored air flow would evolve the spatial energy to such a point, which couldn't help but make Luo Lin's heart ecstatic!

"Come!"

With a gesture of his hand, the pitch-black space tree flew out of the colored air stream with a whoosh, and then came to him.

As the owner of the space tree, Luo Lin can clearly perceive that the space tree can no longer absorb a trace of energy in the colored air flow, obviously, after reaching the ultimate form, the growth of the space tree can only rely on the slow absorption of the free space energy in the heaven and earth in the future, and cannot rely on the color air flow to evolve rapidly again, so Luo Lin recruited the space tree back.

Looking at the black tree in front of him, exuding wisps of spatial fluctuations, the corners of Luo Lin's mouth curled up, and he saw that with a hook of his fingers, the black tree flew into Luo Lin's body at once.

"Buzz ......"

In the cave that had just regained its calm, there were suddenly violent spatial fluctuations again, and I saw that a layer of strong invisible fluctuations suddenly appeared on the surface of Luo Lin's body, making the space around him slightly distorted.

"Space energy is released!hahaha...... Sure enough, you don't need to cultivate to show it!" Luo Lin laughed excitedly.

It turns out that this 'space energy release' is the key to entering the space gate this trip, and only by making the space energy release can you pass through the space gate and enter the dimensional medicine valley!

Before the space energy enters the colored airflow, the space seed is still in a germination state, Luo Lin has to practice for at least a month to be able to achieve the effect of space energy release, and now, the space energy has directly evolved into the space tree, naturally this step is saved, Luo Lin can directly release the space energy without the slightest cultivation.

"Hehe, let's test another magic power of the space tree!" After experimenting with the release of space energy for a while, Luo Lin withdrew the space energy into his body, and then he was ready to start experimenting with another magic power of the space tree.

The space tree that takes tens or hundreds of years to evolve naturally does not only have the magic of spatial energy release, Luo Lin is ready to try another extremely powerful magical power at this moment!
