Castle of Black Iron

It was hills and basins in the periphery of Xuantian Eighteen Mountain Peaks. The largest basin covered over 16,000 square miles. The basins were surrounded by grotesque and magnificent high mountains. The lowest mountain was over 1,000 m high. Looking down from the sky, the mountains around those basins were like petals of an open flower. However, Xuantian Eighteen Mountain Peaks looked like special stamens in the flower.

After a few months, a wide and tidy industrial park covering about 10 square miles had been built near that town of the residence of Iron-Dragon Sect at the foot of the Xuantian Eighteen Mountain Peaks.

Outside the industrial park was a universal airport, which was connected to Tongzhou Province, Yanzhou Province and Youzhou Province through railways and highways.

Zhang Tie directly took Commander Cheng and Gao Tianqi into a factory of that industrial park.

The factory director was selected from one of those dare-to-die people who was gifted by Lord Guangnan’s Mansion. Of course, he knew Zhang Tie. After Zhang Tie expressed his intention here, the factory director fetched three sets of clothes and let Zhang Tie, Commander Cheng and Gao Tianqi put them on. After that, Zhang Tie took them into the workshop of the factory.

“All the workshops of Fiery-Oil incendiary bombs are anti-explosive. Anything that might cause sparkles through friction is forbidden inside. According to the production regulations of the factory, people are not allowed in unless they wear special uniforms.” Zhang Tie explained to Commander Cheng.

Commander Cheng and Gao Tianqi didn’t refuse to put on special uniforms. Whatever, each industry had their own regulations and requests which were not transferable according to the status and power of the visitors. Even Emperor Xuanyuan couldn’t stop an accident if he entered there without the anti-explosive uniform.

In the following half an hour, Zhang Tie introduced the entire production process of Fiery-Oil incendiary bombs to Commander Cheng and Gao Tianqi.

The main material of Fiery-Oil incendiary bomb was Fiery Oil. They made Fiery-Oil incendiary bombs by mixing Fiery Oil with carbon powder, thermit reagent and palmitic acid according to certain proportions.

Carbon powder was a very ordinary industrial raw material, which could be acquired through the fractionation of coal under high temperature.

Thermit reagent was made of aluminum powder, alum powder and limonite powder according to certain proportions.

Palmitic acid could be acquired from palm trees or animal fats such as lard and beef tallow through saponification.

As the main raw material of Fiery-Oil Incendiary Bomb, Fiery Oil could be acquired through the fermentation of straws.

After knowing that Fiery-Oil incendiary bombs could be acquired only by mixing these ordinary raw materials, Commander Cheng watched Zhang Tie with a more amazed look.

“If so, what’s the cost of a 500 kg’s Fiery-Oil incendiary bomb?” Commander Cheng asked Zhang Tie.

“Less than 10 gold coins!” Zhang Tie replied honestly.

“No limit on output?”

“Yes, as long as these raw materials could be provided constantly and the capacity of the factory could catch up with that, the output of Fiery-Oil incendiary bombs is indeed unlimited!”

“Do you know the cost and raw materials of a 500 kg’s white phosphorous gel incendiary bomb?”

“White phosphorous gel incendiary bomb is indeed expensive. Additionally, it’s made of over 40 raw materials, some of which are rare. Therefore, we could barely realize a mass production of white phosphorous gel incendiary bombs!”

“I really wonder about your brains. How could you develop such a marvelous thing!” Commander Cheng let out a long sigh.

“I just mentioned it. It’s my subordinates who developed the Fiery-Oil incendiary bomb. Actually, as long as they have Fiery Oil, many people could figure out the formula!”

After visiting the workshop of Fiery-Oil incendiary bombs and entering another workshop, Commander Cheng’s eyes turned bright at once.

“These are Fiery-Oil spears and Fiery-Oil grenades…” Zhang Tie answered.

This workshop was producing individual weapons instead of heavy Fiery-Oil incendiary bombs which were dropped by airships or airplanes. They were actually two minimal Fiery-Oil incendiary bombs. As for the Fiery-Oil grenado, it looked like an average bottle with a wooden handle. It was similar to the grenade that humans used before the Catastrophe. As for Fiery-Oil spear, it was longer than 1 m in the shape of a spear. It could be thrown. The former one weighed about 1 kg while the latter was lighter than 3 kg.

Commander Cheng couldn’t help but hold them and made some gestures to throw them. Closely after that, he realized the strengths of the two weapons. As they were portable, they could absolutely be individual weapons on the battlefield; besides a Fiery-Oil spear, throwing troops could be established which could further narrow the gap between human corps and demon corps.

As long as a LV 9 demon fighter was struck by a Fiery-Oil spear which was thrown by a LV 3 or LV 4 human fighter, it was destined to die. Similarly, Fiery-Oil grenade also had a great destructive power over a short distance.

“Will you match Fire-Dragon Corps with these weapons?”

“Yes, I will match a part of soldiers with these weapons. After they gain experiences in using them, they could make improvements in them. When the corps come into being, I will match the entire corps with these weapons. By then, the Fiery-Oil grenade will be the standard weapon of the fighters of Fire-Dragon Corps. Each fighter should carry at least 3 Fiery-Oil grenades. According to my plan, Fiery-Oil spear fighters would become an independent arm of the services. A squad should have at least 3 Fiery-Oil spear fighters; a platoon should have at least a squad of Fiery-Oil spear fighters; a company should have at least a platoon of Fiery-Oil spear fighters and the like. Fiery-Oil spear fighters should not be fewer than 1/3 of the total ground troop in the frontier…”

“That’s a high percentage! Are you confident about that?”

Zhang Tie became silent for a few seconds before lowering his voice, “I’m not the most powerful fighter in Taixia Country; however, I have the richest experience in fighting demon fighters on battlefields. I’m clear about the combat mode of demon corps, the combat abilities and features of demon fighters. Commander Cheng, you might not have sensed how disappointing it was when common human fighters faced corps of LV 9 demon fighters. When in Selnes Theater of Operations, due to the sharp difference in the battle strength between two parties, many brave human fighters couldn’t even have a LV 9 demon fighter die with them. Millions of human elites over Waii Subcontinent couldn’t resist the corps of 100,000 LV 9 demon fighters…”

“I don’t believe that human fighters are afraid of death or our humans lack eggs than those demons. Sometimes, even the timidest person would pluck up his greatest courage on the battlefield at the critical moment. We have many dauntless human fighters; especially in the dilemma. However, what makes human fighters most despaired and scared on the battlefield is that they find that they will die in vain. By then, they would collapse mentally and couldn’t stick to their belief; they would be waiting to be slaughtered. As long as 10 human fighters could kill a demon on the battlefield, their sacrifice would be meaningful…”
