Times Have Changed, I Awakened the Hot Weapon

The earth was hit by an asteroid, causing global mutation! The size of the earth has expanded hundreds of times, and various organisms have gained thousands of times their genes. It also changed the elements of the earth, making all the thermal weapons used by humans to rule the earth ineffective. Fortunately, everyone gets an evolution panel, and everyone can awaken exclusive weapons and evolve themselves by killing alien beasts. Su Chen, who was originally a top killer on the earth, accidentally traveled to the mutated era of the earth 500 years later and became a student of Tianhuo Academy. In this world without any thermal weapons, he has awakened his exclusive weapon 'God-level thermal weapon'! While others were still competing to see whose knife was faster, he had pistols, machine guns, and sniper rifles in his hands... This novel and its characters are purely fictitious.
