After Traveling Through Time, I Was Almost Killed by a Boss

[Travel + space + no system + decisive killing + no holy mother + establishing power + no harem + relaxed and happy + no abuse of the master + fast pace + semi-cool writing + invincibility in the middle and late stages] Chen Fan has been working as a cow and horse in Blue Star for more than thirty years. He accidentally traveled to a different world. He thought it was a parallel time and space with the ancient Dragon Kingdom. He wanted to create wealth by relying on his modern knowledge! Unexpectedly, it was a world of cultivation where warriors practiced. Chen Fan was a little helpless and could only look forward to the arrival of the golden finger or system every day. Chen Fan was born in this different universe for fifteen years and still didn't have a golden finger or a system necessary for time travel. Chen Fan was ready to accept his fate. Later, the Chaos God Emperor, the boss of this different universe, took a fancy to Chen Fan's body and wanted to take Chen Fan away. However, he was conquered by the powerful soul of Chen Fan's time traveler. The Chaos God Emperor failed to seize the body, so he had to accept Chen Fan as his apprentice. He passed on his inheritance to Chen Fan and gave Chen Fan the cornerstone of the Chaos God Realm, the Heart of Chaos. Chen Fan has the inheritance of the Chaos God Emperor and the treasure of the Heart of Chaos. Chen Fan is like a cheat, and he is proficient in all the alchemy weapon arrays. He created an auction house to earn a large amount of training resources, and opened a restaurant in the style of Blue Star to earn spiritual stones from warriors. Chen Fan built the Heaven and Earth Alliance to create the power of Qingfeng Sect to protect the value of his industry. Chen Fan relied on his own efforts to prosper in the other world, and... Step by step, relied on his own efforts to become the master of the entire God Realm. The introduction is weak, please read the text for details~~~
