My Daughter Blew Herself up and Died, and I Vowed to Kill Her Forever.

The eternal demon world invaded the earth, and Zhao Yang traveled through time. He started to become stronger with the proficiency system, and married a wife and gave birth to a daughter in just a few years. But then his wife died in battle, and Zhao Yang raised his daughter alone, gradually falling into the trap of laziness of trying to get stronger. It wasn't until the day when my daughter blew herself up that she suddenly realized what she was doing. In this new world. Force is the ultimate law of all things. Killing is the only truth. The only thing Zhao Yang has to do to avenge his daughter is to make himself stronger. I see, I kill, I destroy.
