166 Working Out

Elder Guliva was in doubt if he should hear him.

"How will you make it?"

Rean then explained the concept behind the insulation. Of course, he made it look like he found about it by coincidence. As for whether Guliva believed him or not, that didn't matter.

Guliva didn't know if Rean's idea would really work, but he seemed really confident about it. After pondering a bit, he decided to at least give a try. In the worst case, they would only lose a few days of work.

"How many cultivators would you need?"

Rean smiled before saying.

"Lightning Affinity, I probably need just two, but I will ask for four of them to help carry more tests. As for Earth Affinity, I will need their help to put the wires underground, so ten or so should do. I might need some other types later too, but I'll tell you in advance when that happens. As for Blacksmith Hall, I obviously need their help to help me make the cables."
