The "Psychic Shield" is better than nothing for Renn. He rarely uses even the more powerful "Level Shield".

The only eight-ring spell mastered by the spiritual sucking monster's master is the "Psychic Storm", which has a huge range. All enemies within the spell range will suffer continuous mental impact and physical damage, requiring the guide of the spellcaster, and consume a lot of soul power.

Rennes fuses the soul of the Blue Dragon and already possesses the Thunder Cloud Storm. The power of these two spells is roughly equal, so I don’t care much about it.

He just wants the heart of the master's mind, and it doesn't matter if he removes all other elements.

At this time the soul rises and ends.

Rain did not hesitate to put the soul stone on his eyebrows, sucked out the demon soul of the spirit-sucking monster's main brain, and entered his own soul space.

The world tree shook and swayed.

The fusion begins.

This is the second time that the soul merged with the demon soul after the soul transformation. The main brain had a strong conflict with the blue dragon. Rennes inspires soul shocks again and again to suppress the conflict between the two demon souls.

The main brain demon soul climbed step by step along the trunk of the World Tree.

Rennes, sitting cross-legged in the meditation room, had his expression twisted from time to time, as if he was enduring pain. After more than ten minutes, his expression calmed down and he opened his eyes.

The integration was successful.

On the highest level of the World Tree, a new branch grew next to the Blue Dragon Soul, with thirteen leaves on it, five fewer than the original elements of the Spirit Sucking Monster's main brain.

Rennes breathed a sigh of relief, his eyes full of luck.

The fusion of the demon soul of the main brain is much more difficult than imagined. The conflict has not been fierce before, the degree of fusion is very low, and five elements have been lost, namely "Fear Technique", "Group Fear Technique", "Thinking Stealing", "Psychic Shield" and level 8 "Self-Healing".

Fortunately, these five elements are not important, and it doesn’t matter if they are lost.

If the "master brain heart" is gone, he will be stunned. He will definitely not dare to find Master Augulevi to get another one. He can only return to the dark area and find another community to attract monsters.

The second thing to do is to waste a chance to merge the demon soul.

Rennes opens the phone interface.

His eyes fell on the icon of "Heart of the Master's Brain", which was a brain pattern. The number "1" was displayed on the right side of the progress bar below, which means it was only one level.

Sensing the element runes on the world tree, a stream of information flashed through my mind.

The first-level master brain heart can create and control eight brain divisions, and upgrade to the second level, and double the number of brain divisions, but it must devour at least fifty ordinary spiritual sucking monsters. The higher the level of the master brain heart, the more spiritual sucking monster brains needed to upgrade, and the number will increase wildly, as if it is a bottomless pit.

Elaineto has less than a hundred spiritual monsters. Based on this, Renn judged that Master Agulevi's master brain heart should be level five, with a maximum of 128 brain splits.

Master Agulevi has been in the dark area for hundreds of years, hunting countless spirit-sucking monsters, but only upgraded to level 5, which shows how difficult it is to improve the heart of the master's mind.

Perhaps it is not enough to eat all the spirit-sucking monsters and master brains in the world.

But this is not a problem for Rennes.
