the most generous master ever

Ye Qiu transmigrated to a world of barren wastelands. He obtained the 10,000 Fold Return System.
By teaching or giving his disciples something, he could obtain high critical chance returns.
[Ding! You gave your disciple a Marrow Cleansing Pill. You activated a 1000 fold critical chance. You obtained a God Marrow Pill.]
[Ding! You passed on ten years of cultivation to your disciple. You activated a 100 fold critical chance. You obtained 1,000 years of cultivation.]
[Ding! You gave your disciple a superb grade treasure, the Zixia sword. You activated a 10,000 fold critical chance. You obtained a Deity Sword Cloud.]
His disciples praised, “Master, you are so generous. You always give us everything you have.”
