The demon soul of the ancient black iron dragon was taken out and entered the soul space. It appeared at the root of the world tree and let out an invisible roar.

"snort."

Renne felt contempt in his heart, and immediately stimulated his soul to shake, making the dragon soul honest.

The ancient black iron dragon's demon soul is very powerful, but no matter how strong it is, it is not as good as Rennes. It has no advantage in its rank. It is soon defeated by repeated soul shocks, growing downward at the bottom of the world tree, and eventually turning into a thick tree root.

After being promoted to the Holy Soul Wizard, the new fusion of demon souls no longer transformed into branches, but into roots.

This is the third holy-level demon soul he has merged.

With an extra tree root, the entire world tree will grow, and the outer structure of the soul space will also be added to one layer, one step closer to the next transformation.

Renn opened his eyes, looking relaxed.

"A level 22 wizard."

He was quite happy, but he was not surprised by the smooth fusion of the demon soul. The soul wave frequency of the ancient black iron dragon was very close to him, with a success rate of more than 95%, and the degree of fit was also extremely high, so it was almost impossible to fail the fusion.

As soon as he reached the level 22 wizard, Renn immediately invested the power to fill the third round of power, and entered the state of soul rising.

"As long as there is a suitable holy demon soul, you can upgrade at any time."

Renn shook his head.

He has few demon souls that he can like, and even fewer suitable. With his current strength, it is not very useful to merge one or two demon souls, and the level does not make much sense, unless he can obtain very powerful and rare legendary elements.

The newly merged ancient black iron dragon seems to be powerful in the "metal field", but in fact it cannot enhance its combat effectiveness.

Time stops and space freezes, and this set of battles will end when used.

There are few opportunities to use in the metal field.

Its level 16 "power" is superimposed with its own power element, and it has been upgraded to level 18. This is better than nothing, because it can increase its power to level 20 at any time, and there is no difference between power level 17 or level 18.

The real useful one is "full metal induction".

However, there is also a problem. Only the body has full metal induction and cannot be copied to the clone. If you want to find a mine, you can only find it yourself.

It is definitely not efficient to be the only one, and it takes too much time.

Rennes couldn't think of a good idea for the moment, so he could only do this for the time being.

He stood up and looked around the Dragon Nest Hall again. This place was very hidden and well-placed. It was very suitable as his secret base in the Mist Mountains. He could create a group of thunder casting soldiers to enter, arrange cross-plane teleportation arrays, and build production lines based on local materials.

"The treasure is here."

Renn teleported back to the Star Destroyer and seized the time to create the Thundercast Sky Soldier. He fused the Demon Soul to upgrade for more than ten minutes, and the power he absorbed was used to enhance the Dark Angel, and he failed to maximize the efficiency of power and time utilization.

Racing against time to use the creation technique and the heart of the master's mind, one after another, the thunder-casting heavenly soldiers walked off the operating table.

Two hours later.

When Rennes created hundreds of Thunder-cast Heavenly Warriors, and at the same time, seven or eight dark angels became complete bodies, and pushed the "Minecraft" activation progress bar to about 30%, the battle in the Wanglong Fortress was over.

The demon had been killed so scared that he surrendered to Eloticia in a collective manner.
