Setting up a Stall and Telling Fortunes, I Became a National Master

I was a graduate student, but I suddenly traveled through time and became a fortune teller who offended the powerful and became a poor man. He unexpectedly gained special abilities and was able to gain insight into everything through modern knowledge and fortune-telling techniques. With this ability, I no longer allow others to bully me, and I skillfully deal with difficulties and punish bullies. Although he later experienced crises such as kidnapping and pursuit, he still relied on his skills to avert danger. In the end, I exposed the palace conspiracy and became famous. I also relied on my accurate prediction of disasters to counterattack, became the imperial advisor of the dynasty, and wrote a legend!
