In the sky above the Underground City, Zhou Hao, who was wearing silver armor, flew for about half an hour before discovering a strong reaction from the "essence iron mine"! Zhou Hao followed the detector and arrived in a dilapidated house.
As the detector extended to a range of 9,000 meters, Zhou Hao discovered a lot of text and some armor made of "essence iron". In just ten minutes, Zhou Hao had stored all the precious materials and the ancient text in a special backpack. He also recorded all the ancient texts. He had also sent them to the frog.
Suddenly, the detector emitted an ear-piercing alarm! It trembled. "From the reaction of the detector, there must be something valuable in this room," Zhou Hao said in surprise.
