After realizing that the seawater inside the Stomach Space could be absorbed just like steel and used to convert Energy Value, Zhang Yanhang immediately set the absorption efficiency of the steel cubes he had just swallowed to 0%, as he intended to keep these steel cubes for future strength testing.
Unfortunately, although Zhang Yanhang adjusted it in time, due to the rapid absorption efficiency of the Stomach Space, half of the steel cubes had already been absorbed, leaving only five hundred thousand tons, but fortunately, it should still be enough for now.
Moreover, Zhang Yanhang felt that he could later refine more steel cubes to replenish the Stomach Space, as it would be too troublesome to refine them every time he wanted to test strength. Having a surplus in the Stomach Space would be more convenient.
The Stomach Space is large enough that a bit more space won't be an issue. Even if not used later, they can be absorbed safely, environmentally friendly, and without pollution.
