Weapon seller in the world of magic

A week passed away in a blink of an eye;

During this time, Mark was busy implementing his plans for the store and it was going rather well.

He couldn't help but look forward to the day when it reopens.

In the meantime, he won a new type of battle tank from the lottery wheel to sell. The battle tank was based on Merkava-IV from Mark's past world.

With each unit costing just about 7500 gold coins, the main battle tank is something that can destroy any spirit warrior below the high-6-circle realm and is durable enough to block the attacks below the 6-circle realm. Perhaps, the only disadvantage it has, like any other battle tank, is the speed.

But then again, the smoothbore gun (120mm) of the battle tank could attack enemies from as far away as 3-4 km. So, it shouldn't be an issue.
