Yin Yang took a careful look at Xu Mumu's hand, and seeing that there was indeed no issue, he felt a bit relieved.
Yin Yang was a bit worried. His wife's strength seemed to have genuinely increased significantly. How did it increase?
Yin Yang couldn't make sense of it, just as Xu Mumu couldn't. Mutants could absorb zombie crystal cores to enhance their own strength, but in this era, many people can't even get enough to eat, and there are no zombies around now, where could she get crystal cores to absorb?
She was already satisfied to have brought back the strength from her previous life, but she didn't expect it could further increase. It was truly amazing. She found studying these superpowers to be even more interesting than fussing over things in the lab.
Soon, a larger marble slab was moved into the courtyard, which the two of them could barely carry, until Xu Mumu lent a hand.
She punched the marble, which was much larger and sturdier than the previous one.
