Except for the first one, the Count, the latter three were all barons. When the vampire souls in the fourth territory were harvested, the progress bar of the master's mind's heart finally reached its end.

Rennes let the Star Destroyer drive automatically and opens the mobile phone interface.

On the Soul World Tree, the element runes of the master's mind trembled violently and shone with strange light. When they calmed down, they finally advanced to level 10!

Renn sensed it carefully.

As expected, the brain-splitting chips that can be created at level 10 main brain heart doubled to 4,096!

The other effects remain unchanged, and the created Thunder Crown Heavenly Soldier can only copy the elements of their legendary early stage, which is also expected.

"We still need to improve."

"4,096 brain-segment chips are enough, but to create an armored legion composed of thunder-cast heavenly soldiers, it is not enough to see too few. How come it takes three thousand people, right?"

"Making power armor and star destroyers also requires more workers."

"Even if there are ten thousand Leicao Tianshang soldiers, there is no need to be too many."

After thinking for a while, Renn decided to upgrade the heart of the master brain to level 1. Moreover, the heart of the master brain to level 11 will not only double the number of people, but it is very likely that the Leizhu Tianshang Soldier will reach the middle level of the legend, and its strength will surge several times. No Leizhu Tianshang Soldier will be afraid of opponents below the Saint level.

He tried to invest the power, and the progress bar was difficult to advance a little.

"The upgrade requires 20,000 units of power..."

Rennes was surprised that he could only harvest so much electricity in the abyss, and there was no need to think about it in the main material world.

Although the 20,000 grids had a lot of power, he did not change his mind.

"Duke's Territory!"

Eloticia said, pointing to the castle in front.

Ren had long seen a gloomy castle in the distant Black Thorn Forest, and there were large buildings around it. Thousands of vampires heard the movement and looked up at the direction of the Star Destroyer, without knowing that their death was coming.

This is the first duke's lord I encountered, and there is nothing unique except for more vampires.

A vampire in a black dress appears over the castle.

It was the owner of this castle, a legendary high-level vampire, staring at the loud sound gradually approaching, and a solemn look on his gloomy face.

Rennes ignored the Vampire Duke, and the Star Destroyer continued to fly, while allowing the main gun to start charging and aiming at the castle on the ground.

Titan runes lit up on the muzzle, and huge energy gathered.

It takes thirty seconds to charge the Star Destroyer.

The castle is getting closer and closer, and it will enter the main gun range in a few seconds. At this time, the vampire duke in the sky finally saw through the invisible force field. He was immediately scared and his face turned pale, his eyes were full of horror. He didn't expect to turn into a blood mist and flee north.

However, the blood mist it turned stopped in place.

The world is quiet and time stops flowing.

A black figure appeared within the range where time stopped, with a weak expression, Reslin waved his staff at the vampire duke who could not move. Within six seconds, seven or eight spells were instantly emitted. When time returned to normal, the vampire duke was instantly overwhelmed by the spell.

It didn't even see the scene of its castle being destroyed.

Boom!

The Duke Castle was razed to the ground, and this main gun killed nearly 20,000 vampires. The power of the soul power pool rose wildly, and the value soared like a rocket.

The absorption of too many souls at one time actually made Renne feel a little dizzy.

When the power growth stabilizes, there are more than 7,000 grids of power in the soul power pool, and it is still rising constantly, approaching the upper limit of capacity.

"call……"

Rennes breathed a sigh of relief and quickly put the power into the heart of his main mind.

Progress bar advances quickly.

This duke's leader has many vampires, and the main gun has only wiped out about 90%, and two or three thousand vampires survived.

The electric cannons of the Star Destroyer opened fire violently, harvesting their lives frantically.

The Extreme Warrior and the Holy Gang Knight also attacked in advance to prevent vampires from escaping the range of the Star Destroyer and leaking news.

Half an hour later, when the battle ended, the progress bar of the level 10 master brain heart was already half over.
Chapter completed!
