After Jiang Li carefully read all the information about the mechanical demon spirit, he was a little surprised, "It can actually devour souls and evolve itself."

"Yes."

No. ML01 nodded and replied, "Subordinates can indeed rely on constantly devouring the souls of living creatures to achieve the purpose of self-evolution. This is also the ability of the 'Demon Body'."

"Okay, okay."

Jiang Li was overjoyed, "If this is the case, if we can really succeed in self-evolution, wouldn't we be able to keep advancing?"

"By the way, what's wrong with your 'disability'?"

Jiang Li asked.

"Report to the master, because this subordinate is only made from 'seven devil soul fire fragments', and the fragments themselves are incomplete."

No. ML01 answered again, "Because the soul fire is incomplete, it is in a incomplete state."

"As a result, my current subordinates can only be promoted to the mid-fourth level."

"Is there a way to solve?"

Jiang Li asked.

"have."

No. ML01 nodded, "Swallow the soul, self-evolve, complete the imperfections, and reach the level of completeness."

"Eating souls."

Jiang Li pondered for a while, then made a decision in his mind, and operated the control panel, "I will first promote you to the mid-level fourth level."

"Promotion number ML01 Mechanical Demon Spirit."

Jiang Li directly consumed a full 20,000,000 energy points and began to advance to the level of Mechanical Demon Spirit.

Buzz!

A flash of white light.

The promotion is complete.

There was no visible change in the appearance of the mechanical demon spirit, except that the luster of its eyes became brighter, with faint light of psionic energy flowing, and it soon became silent again.

"Thank you Lord!"

No. ML01 saluted immediately.

brush!

[Special unit: Mechanical Demon (Incomplete)]

[Stage: Mid-4th level]

[No.: ML01]

[Skill 1: Fourth-level mid-grade nether energy proficiency]

[Skill 2: Fourth-level mid-level soul control]

[Skill 3: Fourth-level mid-level virtualization technique]

[Skill 4: Fourth-level mid-grade demon body]

[Devil Machinery:...(omitted)]

[Promotion conditions: Unable to be promoted!]

"really."

Jiang Li secretly said.

Just as ML01 said, after being promoted to the middle stage of the fourth level, due to the incompleteness of the devil's soul fire, it is no longer possible to continue to advance.

"Since a soul is needed, soul fire should also be available."

Jiang Li thought.

brush!

then.

Jiang Li unfolded the soul fire column.

The number of first-level soul fire seeds has reached 1,300 without knowing it, there are also 70 second-level soul fire seeds, and there are still eleven third-level soul fire seeds, no change.

Obviously.

This is the soul fire that Jiang Li exploded after he killed the demon soldiers from the seven demon cities in Black Hell County.

Not too much.

"Can these soul fires enable you to complete your self-evolution?"

Jiang Li took out a first-level soul fire, a second-level soul fire, and a third-level soul fire, presented them in front of ML01, and asked: "Also, which one of these three is better?"

"able!"

No. ML01's eyes were slightly bright, and he nodded directly: "This kind of pure white soul fire is the best, absorbing one soul fire is worth thousands of gray soul fire."

"Um."

Jiang Li nodded, "I understand."

"Fusion."

immediately.

Jiang Li began to fuse all the first-level soul fire seeds, one thousand three hundred pieces, which can be fused a total of one hundred and thirty times, ten minutes later.

The integration is complete.

It succeeded forty-five times, failed eighty-five times, and obtained forty-five second-level soul fire seeds.

"Fusing the second-level soul fire."

Immediately afterwards.

Jiang Li then fused the second-level soul fire seeds, one hundred and fifteen, but could only fuse them eleven times. Within a few minutes, they were all fused.

This fusion succeeded twice and failed nine times.

Obtained two third-level soul fire seeds.

In addition to the original eleven, Jiang Li's number of third-level soul fire seeds reached thirteen.

brush!

Jiang Li took out a third-level soul fire, and a white light spot floated on Jiang Li's palm, emitting a faint and soft light.

"Absorb it."

Jiang Li handed it over.

"Thank you, Lord."

No. ML01 nodded, opened his mouth and inhaled, and the pure white third-level soul fire in Jiang Li's palm flew into No. ML01's mouth.

Buzz!

A white light flashed on the body of ML01.

Nothing changes.

"how do you feel?"

Jiang Li asked.

"Reporting back to the master, the 'Demon Spirit's Heart' has indeed been completed. By absorbing nine more soul fires, my subordinates will be able to advance to the late fourth level."

ML01 said.

"good."

Jiang Li nodded without hesitation, and took out nine more third-level soul fire seeds. Nine pure white soul light spots were suspended in front of Jiang Li, with a soft luster.

Buzz!

Then ML01 absorbed all nine third-level soul fire seeds, and a bright light flashed in his eyes, although no change could be seen on the outside.

But after Jiang Li unfolded the information on ML01.

The inability to advance has disappeared and now requires 40,000,000 energy points.

"Promotion!"

then.

Jiang Li spent another 40,000,000 energy points to advance ML01 to another level, to the late fourth level.

"At the late fourth level, I think it should be enough for the time being."

Jiang Li thought secretly: "The most important thing is that I only have three third-level soul fire seeds left, which is obviously not enough to promote No. ML01 again."

"Also, there aren't many energy points left."
Chapter completed!
