What is written in the end?

its something like Liang was taken over by Chao after 5 years , and Chiang took over the other 6 nations and united China. Ge Li traveled around with the kids

There was a revolt in the city of Liang, after which Liang city changed its name. But 5 years later it was conquered by the state of Zhao conquered, and eventually the state of Qin conquered all the warring states.

Ge Li took care of the orphans and continued to travel and preach his beliefs of peace.

Here is a word by word translation.

The cruel Liang king rules without mercy. He faces rebellion five years later. The government officials and the people executed him using the "car split" technique (not sure, probably similar to "horse split")

Not even one year after Liang changed its identity, it is eliminated by Chao.

But eventually Chao is eliminated by Qin (first unification of China)

Ge Li takes care of a crowd of parent-less children. He continues his journey through different nations, to circulate his message of peace.
