The Year 177 of the Alliance calendar, July 7th.
It had been three and a half months since Shi Yu had come to this world. It had also been four days since he became a Beast Tamer.
On the first day, Shi Yu's contractual pet, Iron-Eating Beast Eleven, awakened the Hardening skill and welcomed its first victory, defeating the beast with the greatest population, the silkworms.
The next day, Shi Yu used the Skill Duplication Book to upgrade Eleven's Hardening Skill to the proficient level.
On the third day, Eleven was training like always, upgrading its hardening ability daily.
On the fourth day, the Iron-Eating Beast reached Level 4 and learned an Intermediate healing skill. Then, it started its "falling" training…
Falling training was a good way to train. If the steel plate at the landing point was not broken, it meant that Eleven's hardening strength was not enough, and it could continue training.
