Once the Demiplane had been mostly arranged, it was time to set up the body modification apparatus.
The body modification apparatus was not some sophisticated instrument, but simply a pool filled with psionic energy.
On the already stabilized ground, Su Yu dug out a pool ten meters long and wide, with a depth of roughly three meters.
Su Yu poured concentrated, liquefied psionic energy into the pool until it was completely full.
Next, he cast a spell to isolate the pool from the surrounding space so that the psionic energy within would not spill out.
The body modification apparatus required only this psionic energy pool, with no need for any instruments.
However, Lord Holy Song set up more than a dozen monitoring and analytical devices beside the pool, capable of analyzing the physical condition and various data indicators of those who entered it.
The entire process of digging the pool took less than ten minutes.
After finishing the setup, Su Yu sent a telepathic message to his three confidantes, who were still busy. "The psionic energy pool is ready. Come over."
"So soon?" The three women put down their work and flew over from different parts of the Demiplane.
"Which one of you three is going first?" Su Yu asked.
At the same time, Su Yu asked Lord Holy Song, "Lord Holy Song, who should undergo body modification first? Should Tina go first, since she has the best constitution?"
"There is no need to distinguish an order," Lord Holy Song quickly replied. "Let all three enter together. It may be three at once, but you can completely handle such a small situation."
"Mm, that works." Su Yu nodded.
Without realizing it, the gap in strength between him and his three confidantes had become as vast as the clouds and mud.
