Han Sen initially didn't want Little Seven to participate in the battle body races, but when he heard what they could win if Little Seven achieved first place, he changed his mind. It was a battle body fluid synthesized by the Meka themselves.
Battle body fluid could level Little Seven up. It could turn Baron battle bodies into Viscounts. For the Meka, this was great.
Mach offered Han Sen a very good deal, and Little Seven showed interest in giving it a shot. So, Han Sen agreed to participate.
He signed a contract with Mach. If Little Seven achieved a good result, he could even gain shares in Mach's company. The better Little Seven did, the more shares Han Sen would receive.
If he earned first place in the Baron team, they could gain a forty percent share of the business.
Mach helped Little Seven sign up. He got the permit to join very quickly, and Han Sen took Little Seven to take part in a few of the early matches.
