Undercurrent Fortress's training room is a legacy left behind by the Forin era, Han is unable to make any more improvements to the facility without tearing it down and rebuilding it since the one left behind by Forin is luxurious enough.
Han also found time to reassemble the star apes encountered earlier, using the fusion beast tools he brought with him; he reconstituted the beasts using the body parts of the slaughtered star apes horde. The result was only 30 or so fusion beasts, but in order to take most advantage of star apes' four powerful limbs, each fusion star apes all has 4 legs and 6 arms.
After Han's assessment, the fusion star apes' combat power is about one-third of Godly Armored Beasts. After all, Wuyun only made 130 Godly Armored Beasts in his lifetime, and he invested as much effort as possible for each one of them, so it will be very difficult for Han to produce fusion beasts at the same level of combat power.
