Mountain Eagle spent nearly 50 days scouring almost all the raw material markets around Bangkok and various universities...
It cost nearly 1.2 million Thai Baht to fill the Sergeant's raw material space.
The so-called raw materials are actually various metal powders, polymer granules, and some chemical and rare metal materials.
These are all legal and marketable items, and with a substantial amount of money on hand, Mountain Eagle did not encounter too many obstacles, except taking some time to figure out the sales channels.
The advantage of filling the Sergeant System's raw material space is that, for a long time to come, he will not need to resupply unless he participates in high-intensity warfare that consumes a lot of ammunition and equipment.
When Mountain Eagle was in China, he had no need or motivation to manufacture equipment, and he only managed to purchase some raw materials in the rush after the incident.
