Chương 145: Debut of Tigon series firearms

*Ding! You entered Mark's factory.

*Ding! All your skills are locked.

*Ding! Familiars' inventory is locked. 

"Okay, let's get started." Mark returned to the real world and went to an empty table, taking a seat. Thankfully, for him, a modern pencil was already invented in this world. So, it made the job easier for him.

He spread a big white sheet of paper on the table and then, fell into thoughts.

"Okay, what should be my first weapon? I should also take ammo into consideration in order to use it.

With the help of the system, I can create ordinary 9mm, R.I.P. 9mm, 0.50 caliber, and .204 caliber bullets; 12 gauge shotgun shells, 7.62x51mm, and 7.9mmx57mm ammo.

9mm is too weak unless I need to make a weapon that can shoot it with at least mach5 or above speed. It's too much of a hassle and I have already too many types of pistols.
