Where did Fan Ye learn the six techniques of karma boxing?

When Ziweixing's old madman taught him, he gave him nine secrets.

As can be seen from the book, the six divisions in the Karma Boxing Wheel are created by a great power of the Eucharist, which is a set of boxing methods very suitable for the Eucharist. Many people think that it was created by Shi Hao.

After the Six Masters of Karma Boxing Wheel, he was learned by an old madman from the forbidden area. Later, Fan Ye came to Wei Zixing domain with a coffin in Kowloon, where he met the Archaean royal family sleeping in space. Later, the old madman appeared in time, helping Fan Ye and the whole Wei Zixing domain to lift the crisis. They fought in the void, and in the process of fighting, the old madman taught Fan Ye the six divisions in causal boxing. The old madman blew up an ancient royal family with the six divisions in the wheel of causal boxing!

I hope it helps you.
