Why are there both zero-handed hands and Xia Lan hexagrams in Xia Lan's exhibition pool?

Because Zero injected the vitality of Chivalan into Zero's embryo in order to deal with Chivalan, but all failed. Only the timid Nian Chi survived. Considering that Nian Chi could not survive in the future, Zero locked him up and left him to fend for himself. By chance, Nian Chi escaped, and his hot mom and sister Mo Yi took him in. Therefore, Nian Chi has both Xia Lan and zero force.
