Chapter 206

Twenty thousand soul crystals, for Yun Shen who had just built the Profound Heaven Research Institute at that time, was simply an astronomical figure, which he couldn't afford at all, let alone needing a piece of 【Scientific Crystal】.

But now it was completely different. A mere twenty thousand soul crystals, what was there to worry about?

"Recruit!"

【You consumed Scientific Crystal (Legendary) ×1, Source Crystal ×100000, Soul Crystal ×20000, and successfully recruited Profound Heaven Researcher ×10.】

Ten women with stunning beauty, wearing researcher uniforms with white backgrounds and silver edges, appeared in the Profound Heaven Research Institute.

Among them were tall imperial sisters, petite lolis, pure girls, plump mature women...

"Upgrade!"

【You consumed Soul Crystal ×2235000 to upgrade 10 Profound Heaven Researchers (Legendary) to level 10.】

Seeing this, Jiang Lan summoned a small aircraft, which looked like a water kayak, but in fact, ninety percent of the materials consumed during the creation were metal.

This aircraft was not brought with the Profound Heaven Research Institute, but a "small toy" that Jiang Lan made casually.

It was mainly because the initial size of the Profound Heaven Research Institute was too large, the territory area was insufficient, and it was not suitable for landing. If it kept floating, it would be too troublesome for the people below to go up.

So Jiang Lan spent some time creating this extremely simple aircraft. It couldn't do anything big, but it was definitely no problem to transport a small number of personnel to and from the Profound Heaven Research Institute.

Subsequently, Yun Shen and Jiang Lan took the aircraft together and arrived inside the Profound Heaven Research Institute.

He rarely came here on weekdays. After all, he didn't understand any research, and coming here just caused trouble for Jiang Lan, delaying her research progress in vain.

When the entrance cabin door opened, ten stunning beauties with charming appearances stood on both sides of the entrance, welcoming and saluting him neatly, as if they had gone through countless rehearsals.
