After confirming there were no issues with the product, Ma Li took out a few shells and bullets, fitted a primer onto the bottom of the shells, inserted the steel core into the bullet head, and brought them to the leader.
Bai Ye took them, removed the insulated cup from his waist, aligned the mouth of the bullet shell with the cup's outlet, then controlled the liquid hydrogen and liquid oxygen from the cup to pour into the bullet shell, forming a hydrogen-oxygen mixture inside.
As the fuel and oxidizer were injected and the liquid vaporized, a thin layer of frost formed on the surface of the shell, dissipating and evaporating quickly in the over thirty degrees high temperature.
The bullet shell was held mouth down to prevent the hydrogen-oxygen mixture from escaping excessively.
Of course, Bai Ye's superpower was indispensable in expanding the space and controlling the amount of fuel in the shell.
