Originally, Xiao Shi's seven clones that cultivated the system of other eras were like the main body. They were independent lifeforms. Once they died, they would truly die and could not be reborn. But under the immortality of Xiao Shi's Behind-the-scenes Heavenly Dao, These seven clones also obtained the same characteristics as the main body. As long as he did not die from exhaustion, he could be reborn through the Behind-the-scenes Heavenly Dao.
Therefore, Xiao Shi chose to let these clones fight the three demigod Heavenly Kings. Even if all these clones died, he could also revive them all through the Behind-the-scenes Heavenly Dao.
The main body clone that Xiao Shi had sent out was a normal clone formed by the Martial Emperor's Cape. Even without the Behind-the-scenes Heavenly Dao, it could be formed again in 30 days.
Previously, Xiao Shi was not in a hurry to let this strongest clone head to the territory of the three demigod Heavenly Kings.
