The End of the World: I Started the Mecha Era

The end of the world is coming and the virus is raging. Humans can evolve into warriors, but zombies can also be upgraded. Thirty years later, the most powerful warrior can punch ten thousand kilograms of force with one punch, but the zombie king is hundreds of meters tall and can destroy a hill with one kick. There is a huge difference in strength between warriors and zombies. Lin Feng, who was reborn and returned to the beginning of the apocalypse, felt very confused. As the strongest human race in his previous life, he was killed by the zombie king. This proves that warriors cannot save mankind, so where is the future of mankind? He accidentally obtained a mecha manufacturing system, which rekindled his hope. Since martial arts cannot save mankind, then make mechas. If a 20-meter-tall mecha doesn't work, then build a 100-meter-tall mecha. ... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
