After going to the Golden Time and Space and successfully restoring the combat power index of King Arthur Ding Xiaoyu and Wang Dadong, the Alliance Leader and Xia Tian returned to the Iron Time and Space first. King Lanling, because he could not face Xia Mei and was unwilling to delve into whether he really regarded Xia Mei as his sister in his heart, chose to escape and relax in the Golden Time and Space. However, he did not want to be attacked by a demon at this time and was seriously injured. He could only stay in the Golden Time and Space for treatment. After Natsumi learned the news, she wanted to find King Lanling, but accidentally fell into the copper space and time, and met a boy she had saved when she was a child.
