Mortals Cultivating Immortality: Signing a Brother Loan at the Beginning

"Junior Brother Yang, you are my beloved relative, friend, and brother. How could I cheat you?" "Don't worry, Junior Brother Yang, our goal has always been that people from Qi will not deceive people from Qi." Yang Chen believed it and signed the "Sibling Loan". ……. One month later, the monthly interest rate changes from 10% to 30%. Loving relatives, friends, and brothers is what it means. While he has to pay off his debt, he also has to find a way to pass the six-year deadline for the outer sect: the fourth level of Qi training and 800 contribution points. If he fails to reach it, he will be kicked out of the peak. He only had four spiritual roots and was on the second level of Qi training, so he could only forcefully attack the bottleneck - that night he almost went crazy. When he was about to die, all the memories of being a social animal in his previous life came back to him. I woke up and touched it: First, there was no ring for the old man, second, there was no fairy weapon accompanying me, and third, there was no system panel... Yang Chen complained in his heart: "Then what is my 'amazing talent'?" The mysterious jade slip carries the Four Heavenly Eye Techniques: Don't worry, here comes my brother. "( ͡° ͜ʖ ͡°)" "It seems like this is my 'amazing talent'." From then on, he stopped gambling on adventure and focused on the path of alchemy. ……. Many years later, there was an all-powerful old demon Yang in the world of immortality.
