Starting hell mode? Cao Yan traveled through the Three Kingdoms, and when he opened his eyes, it was Cao Cao who blocked the door with a knife. The crime was: filthy Zhang Xiu's Mrs. Zou! The blade hangs from the neck, death row is imminent, activate the system!
In a desperate situation, Cao Yan fought for his life: predicting the changes in Wancheng, fighting in a bloody battle at Yuanmen to save Dian Wei, but he was shot by three spears and was on the verge of death! When he was dying, Cao Cao was shocked to see the red gold longevity lock on his body - this was actually his own son who had been separated for twenty years!
Wancheng was wiped out with blood, and the heroes were furious. On the sick bed, Cao Yan presented a magical picture: an improved thunderbolt car with three times the range and doubled the power! It also predicted that Yuan Shao's key points (Wuchao and Chunyu Qiong) and Liu Bei would rebel!
Cao Cao spent all his private treasury and secretly provided full support.
On the wheelchair, Cao Yan is in charge of the world: the beacon is rising in Guandu, and the waves in the Chibi River are rushing!
Holding the power of the ANBU and the technology tree that transcends the times, a thunderbolt car, the prototype of gunpowder, an abacus, a stethoscope, agricultural water conservancy..., Cao Yan is shocked every step of the way in troubled times.
He is Cao Cao's lost Qilin'er, the "Human Hell" who has no plans left, and he is the pillar of the country in charge of Cao Wei's core technology.
