His thoughts returned to the present.
He must make good use of the 40 summoning opportunities.
After thinking for a while, Jerry finally made a decision.
"Carry out a single summoning!" Jerry said.
In the past when there was no upgrading setting, Jerry could use the summoning opportunities all at once.
But now that he could upgrade the mythical figures, gods, and historical celebrities besides summoning them, he must be very careful.
If he wasn't careful, he might summon a group of people with low level. They would be useless to him, right?
Therefore, summoning one figure at a time was the most cost-effective way to do it. If the people he summoned were valuable, he could directly upgrade them.
If they were just civil officials and strategists, he'd not upgrade them for the moment.
