Ph. D. in Biology: I Turned into a Giant and Swept Across the World

Liu Xing was a doctoral student in biology. He was about to graduate and become a doctor. He suddenly fell into a coma while doing experiments one day. When he woke up again, he found that he had traveled back to the classroom where he was 18 years old. The teacher was still talking tirelessly on the podium, but before Liu Xing could get excited, he discovered that this world did not seem to be the world he was familiar with. "Xiao Wang, the student next door, knows his military skills by heart! He can summon hundreds of ancient soldiers in an instant. He is the first in age this time. Everyone must learn from him." Everyone responded one after another. "Teacher, I have made another breakthrough in chemistry recently! Next time I will definitely knock down the kid next door!" A classmate in the class said positively, and a pistol condensed out of thin air in his hand! "The art of making iron out of thin air! No substitution reaction is used! It seems that classmate Guo Xue has worked hard! Everyone must work hard! We can't always let one class have the upper hand on everyone!" Looking at the pistol in Guo Xue's hand, Liu Xing felt dizzy. Did he learn chemistry to make a gun out of thin air? ! Summon ancient soldiers by reciting the teacher's instructions? ! So what can I do with a PhD in biology? That year, the top scorer in the national college entrance examination appeared in the biology major for the first time, and the 15-meter-tall giant swept the world!
