Listening to the description of "Little Flower", the protagonist immediately realized what those precious goods were, and ran impatiently to the ground.

The caravan of bullet ants stopped at a flat ground on the ground of [Xinyang City], and the swarms of locusts of huge size and dark green were densely packed together, and the goods were bulging under their bellies.

The protagonist resists the urge to lean over and look at the goods, and first meets the captain of the bullet ant caravan according to etiquette, and then meets the male ant trade representative of the Black Fire Ant clan who follows the caravan.

The black fire ant male ant trade representative then took the protagonist to see their goods.

I saw that on the stomachs of the locusts, there were bags made of plant fibers, which were filled with black stones, which could still shimmer and reflect in the sun.

The protagonist touched it with his tentacles, and combined with the introduction of the representative of the black fire ant, he determined that these were indeed coal!

Coal is a solid flammable mineral that was gradually formed by ancient plants buried in the ground and undergoing complex biochemical and physicochemical changes.

Coal is known as black gold, the food of industry, and is a very important fuel and chemical raw material.

The tentacles of the black fire ant representative leaned over and began to introduce it, interrupting the protagonist's association.

The representative of the black fire ants said that these black stones were sacred relics inherited by the god of fire, and that with this holy relic, the power of the god of fire could be harnessed to cook delicious food.

The representative of the black fire ants immediately summoned several worker ants who had come with the caravan, and the worker ants skillfully untied a cargo bag and formed a cone-shaped pile of coal that had been processed into a suitable size in the clearing.

They came prepared for a live demonstration.

At the request of the representative of the black fire ants, "Little Flower" ordered the workers in the country to bring in some dried mealworms.

I saw that the black fire ant worker ant brought a small clay pot, opened the lid of the mud seal, carefully took out some viscous blue-black liquid and smeared it on the coal pile, and then quickly sewed the jar shut, and carefully wiped off the liquid on his big jaw with the dry sand on the ground.

Two black fire ant worker ants took a hay stalk that could be seen everywhere, one after the other, and rubbed the hay stalk against the coal pile stained with a blue-black viscous liquid.

After a while, I saw green smoke coming out of the coal pile, and it was actually lit.

The protagonist knows that coal is not so easy to light as a fuel, and in the past, the earthen stoves in the countryside had to be lit with sawdust and fine wood to ignite the coal.

Unexpectedly, the black fire ant clan actually has the materials and methods to ignite coal.

The Black Fire Ant clan didn't know that the Ant Alliance also had the technology to use fire, and the Black Fire Ant representative proudly let his subordinates demonstrate the technology of grilling mealworm jerky on the spot, and then tried his best to persuade the protagonist to taste the delicacy of this "fire god".

The protagonist doesn't plan to reveal the secrets of his country, waits patiently for the food to be baked, and reluctantly eats some barbecue without salt or spices, and praises it against his will.

The representatives of the Black Fire Ants immediately stated that they were willing to exchange the sacred relics of the Fire God for honeydew and crow honey, and would also teach the Ant Nation the secret of using fire to barbecue, and then gave a sky-high transaction price...

The black fire ants were asked to exchange a bag of coal for ten snail shell honeydew or one snail shell honeydew to give away the fire, and this time they brought 12 bags of coal......

The protagonist is speechless, you are really profiteers, if I didn't know this thing about coal, and I also have the technology to use fire, maybe I was really blinded by you.

The protagonist immediately states that these so-called holy objects can only be used to process food, and have no other use, and are not worth the price.

The black fire ant trade representative was in a hurry, and a message came from his tentacles, saying that the holy fire could also burn pottery. After saying that, the black fire ant representative tentacles came with remorse again, perhaps he had just inadvertently leaked the secret.

Firing pottery has always been the secret recipe of the black fire ant clan, relying on this specialty to return things from other ant clans, but I didn't expect that there was no way to spend money here in the ant alliance.

The Ant Alliance did not reveal the secret that it could use fire to make better pottery, but resolutely refused to buy the high-priced pottery of the Black Fire Ant Clan, and symbolically exchanged a snail shell honeydew for a set of pottery.

The elite of the Black Fire Ant Clan, however, were already fascinated by honeydew and crow honey, and after learning that the other tribes had more or less exchanged their specialties for honeydew and crow honey, they couldn't understand why their own specialties were not marketable.

In the end, the Black Fire Ant clan decided to take out the treasure at the bottom of the box, which was coal and a mysterious ignition liquid.

There is an open-pit coal mine in the territory of the Black Fire Ant Country, and its reserves are the level of a small black coal kiln for the human world, but it is inexhaustible for an ant kingdom.

This open-pit coal mine is easy to excavate and produces the best natural anthracite, and it is on this resource that the Black Fire Ant Kingdom has an inexhaustible supply of fuel, and has developed its own food cooking and processing technology and pottery firing technology.

Since the other party was not interested in pottery, the black fire ant clan began to sell the technology of using fire to process food, and by the way, they sold the fuel and ignition together.

It's just that the price given by the black fire ants is too outrageous, not that they are reluctant to pay these worthless coal and fire starters, but the cost of renting a bullet ant caravan is too high, and one-sixth of the trade volume has to be given to them.

In addition, the transportation volume of the flying locust caravan is not large, and the coal transported by 12 locusts at a time only adds up to a few grams, and if the black fire ants do not quote a high price, they will not be able to exchange the desired amount of honeydew and crow honey.

The representative of the black fire ant regretted revealing the secret of pottery making, and was afraid that the other party would use the secret recipe as a threat to make a deal.

But the protagonist is not interested at all, and directly cuts the price, and the black fire ant represents that there is also a ghost in his heart, and finally the two parties agree to trade 1 snail shell crow honey for 12 bags of coal, and 1 can of fire starter as a gift.

The protagonist is still very interested in the resource of coal, saying that he can continue to trade coal, and after learning that the representative of the black fire ant said that the trading volume is too small due to the limited transportation capacity, the protagonist gives the black fire ant family 1 can of honeydew and 1 can of crow honey

Although there is not much stock in the treasury at present, this amount is still available.

The representative of the black fire ant was overjoyed and said that he would continue to promote the future trade when he returned.

The worker ants on both sides begin to deliver the goods, and the protagonist also goes home.

Coal, I didn't expect to get this useful resource.

The protagonist has checked, these are the best anthracite, there is very little smoke when barbecuing just now, and there is no choking smell, indicating that there is very little sulfur in it, and it can be used directly instead of charcoal to smelt steel, which is very useful for raising the temperature of the furnace.

The current blast furnace of the Divine Envoy King uses charcoal as fuel, and needs to collect branches to burn charcoal, and the charcoal production is not high, resulting in the iron-making blast furnace being empty for most of the time.

If sufficient coal can be used as fuel, the iron production of blast furnaces will be greatly increased, and the black fire ant representative can say that there is as much coal as it wants!

It's all about how you transport it!
