Zero Zone: Thunder Mastiff Emperor

Armor one + absolute zero. West Shuo traveled through time and became a test subject of a praise society in the Zero Zone. The praise society planned to train him into a top killer, but he repeatedly failed in training and suffered the punishment of electrocution all year round. However, after years of torture, the armor system was awakened and the Golden Shadow bloodline was activated. The snow mastiff armor sensed the danger of the summoner, automatically protected its body, killed all the people and escaped from the praise meeting. However, west Shuo, who had escaped, was not reconciled and started on the road of revenge against the Praising Society. (Let me explain, this book is considered a development stream. The protagonist is not Long Aotian. The protagonist may be useless in the early stage, but he will gradually grow up and get better in the later stage.)
