Li Mo stared at the glass jar containing the spiritual root and spiritual energy, and his head was faintly swollen by the memory fragments gushing out of the Creation Book.

While digesting his memories, he learned a lot about Reiki.

To be precise, it is the aura of the ancient immortal cultivation world.

Seven thousand years ago, the aura was colorless and formless, and it was a very pure energy, and only after the concentration reached a certain level, it would take on the form of clouds.

Reiki exists in any corner of heaven and earth.

At that time, the monks could not restrain the aura, and even with the help of the spirit gathering array, it only made the concentration of the aura slightly higher.

Only naturally formed spirit veins can mine crystalline spirit stones.

The Immortal Cultivation Sect is also generally located around the spiritual veins, using a large spiritual gathering array to collect the spiritual energy leaked from the spiritual veins, forming a blessed land cave heaven.

According to the concentration of spiritual energy, the grade of spirit stones is divided into lower-grade spirit stones, medium-grade spirit stones, high-grade spirit stones, and top-grade spirit stones.

Li Mo looked at it from the perspective of the Heart Beast Sect.

The system of the ancient immortal cultivation realm was completely based on aura, and the characteristics of aura were only the five elements of gold, wood, water, fire, and earth.

The spiritual root is the organ used by the monk to absorb the spiritual energy, and it is also based on the spiritual root of the five elements, which is equivalent to the qualification.

The monk's spiritual root is located in the Mud Pill Palace, and it is shaped like a rhizome.

The purer the spiritual root, the higher the cultivation efficiency, the single spiritual root is called the innate Dao species, there is no bottleneck before the Jindan period, but the five elements miscellaneous spiritual root is difficult to break through even the foundation building period.

Li Mo looked at the large number of glass jars in front of him.

In a glass jar, the aura was purple and viscous, and the five internal organs spiritual roots soaked in it were covered with coral-like cuticles on the surface.

There are more than 60 jars in the room, and the types of aura are almost the same, some are like magma, or smoothies, and the most bizarre thing is the aura composed of a large number of worms.

Click......

There was a sound of metal crashing from upstairs, and it seemed that a behemoth was slowly crawling up.

Li Mo knocked on the wall, although the exterior was covered with layers of wooden planks, the inside was made of metal ore smelting, so it was extremely strong.

The mountains near Molten Town have not heard that iron ore is abundant, and the medical hall actually used a few tons of metal to build a house, is it just to accommodate the aura?

Li Mo swallowed.

I always feel that the glass jar that carries the aura is extremely dangerous, as if it contains drops of liquid bombs that are about to explode.

"Ahem, ahem."

"Little doll, who told you to come to the old man?"

"Steward Hu asked me to choose the exercises......"

The old and strong male voice echoed through the stairs, and then a body full three or four meters tall appeared, supported by eight spider limbs.

Li Mo took a few steps back, and the door behind him suddenly closed automatically.

At the same time, hundreds of candles in the house were lit one after another, and the glass jars hanging from the ceiling became like bright stars in the dark night.

"Interesting, interesting!!"

Han Cai's head was revealed, and he looked like an ordinary middle-aged man, with a beard hanging down on his chest at an unkempt length.

But his body was at least two meters long, still strangely oval-shaped, supported by eight long, narrow, thin human hands.

Han Cai only had the upper half of his body, wearing a tattered Taoist robe, covering his bloated body.

There were constantly palm-sized spiders emerging from under his robes.

Li Mo couldn't help but feel numb in his scalp, could it be that he had cultivated too many spells and turned into a monster with inhuman characteristics like Han Cai?

More than a dozen Lang Zhong were anxiously chasing after Han Cai, obviously there were still unfinished surgeries.

"You go up first, and the old man will come over naturally."

The one-eyed man in the lead said hesitantly: "Doctor Han, but time is ......."

Han Cai glanced at them, and Zhong Langzhong hurriedly returned to the second floor, leaving the suffocating pressure to Li Mo alone.

"The little doll hasn't started yet, and it's rare for Hu Wen to push you over."

"The total horn period is the process of nourishing the five internal organs with different kinds of aura, so that the five internal organs are transformed into corpse spirit roots, choose your own aura."

Li Mo settled his mind, he didn't know why the aura of the later generations was so weird, but the ancient exercises were obviously not applicable.

He clenched his fists and said, "Please also ask Dr. Han to point out the advantages and disadvantages of aura for me." ”

"Hahahaha, I have the eyesight."

"The type of aura collected by the old man is the largest even in the entire Molten Town."

Han Cai stretched out his arm, and the bone joints made a strange thumping sound, and then stretched a few meters and rummaged through the cabinet next to the wall.

"There it is."

Han Cai took out a piece of bone slip.

"There's Dr. Lao Han." After Li Mo took the bone slip, he placed it in the center of his eyebrows.

Seven thousand years of vicissitudes have changed not only the grass, trees, mountains and stones, but even the aura has changed inexplicably.

The aura is no longer pure, and a large number of different auras with different characteristics are derived.

Clouds, swamps, volcanoes, thunder, plants, bones...... will give birth to xenomorphic aura.

Today's exercises are based on different kinds of aura.

The innate spiritual root no longer exists, so the total horn stage needs to transform the five internal organs into the corpse spiritual root.

The corpse spirit root will have the characteristics of a different kind of aura, so it appears to have different forms.

No wonder it is a fellow practitioner of art and law.

The spell and the xenomorph aura must be compatible, otherwise it will be difficult to exert the power of the spell.

Han Cai picked out a bottle of red and yellow intertwined aura from the glass jar, and the five internal organs inside were also made of rock, and the surface was full of cracks.

"This is the mountain aura, which the old man dug from the depths of a leyline, and the characteristic is that the aura is suitable for all defensive spells."

"Doctor Han, it's not for me."

Li Mo hesitated for a few breaths and then refused.

Painting Tsing Yi was a body protection spell in ancient times, and the mountain aura should be quite suitable.

But with the importance of Hu Guan, it is impossible for Hua Tsing Yi to be so ordinary.

Li Mo wants the heterogeneous aura of the golden oil even more, without obvious shortcomings and drawbacks, and can take into account the vast majority of spells.

"Yes."

"How's the aura?"

He picked up a jar of milky aura.

"The aura of the elixir is taken from the heart of the thousand-year-old tree, and after refining, it supports the vitality of the five organs, and the death of the weak crown period can be delayed for at least fifteen years by relying on the aura of the elixir."

"Or this filthy aura, the source... Ahem, the source will not be mentioned for the time being. ”

"Filthy aura is not difficult to find, the efficiency of cultivation can definitely be guaranteed, not to mention the power, the aura itself is highly poisonous."

While Li Mo was dealing with Han Cai, he was paying attention to all kinds of different kinds of aura.

For him, there is a book of creation, and in the future, it will definitely not be possible to refine only one kind of aura, and multiple imprint organs will be able to increase the number of dantians.

For the first time refining the aura, it is better to be safe.

Han Cai kept chattering on the side, and Li Mo gave full play to his strong thinking ability and brought his heart and soul to the extreme.

Li Mo asked Han Cai from time to time, trying to understand the characteristics of each jar of aura.

He stared at the smoky xenomorphic aura before moving away.

The cloud mist aura is more in line with Li Mo's idea of golden oil, but unfortunately it is suitable for illusion spells, otherwise the offense and defense are inferior.

"Doctor Han, this is ......"

Li Mo pointed to the corner, it was also a jar of cloud-like aura, but it was pale yellow, and the corpse spirit root in the jar was similar to the swamp poison aura, all of which looked like internal organs soaked in wax oil.
