Yan Tielong directly took away nearly 100,000 pieces of multi-layer fine linen clothing from the textile factory, and the cost price of these more than 100,000 pieces of multi-layer fine linen clothing was not even 10,000 gold coins, but the transportation cost was as high as tens of thousands of gold coins, after all, it was necessary to hire carriages and bodyguards to transport them to Shougett City.

Some people may wonder why Yan Tielong didn't use the teleportation array to transport hundreds of thousands of winter clothes, which was not only safe, but also could save tens of thousands of gold coins in transportation costs.

In fact, Yan Tielong had also considered using a teleportation array, but he considered that using a teleportation array for hundreds of thousands of winter clothes was too conspicuous, which would expose the teleportation point.

Qiang Ran Sword Master already knew about the teleportation array placed by Yan Tielong, but Yan Tielong believed that the Sword Saint would not tell too many people about the teleportation array, so Yan Tielong would continue to hide the teleportation array.

And Yan Tielong's payment of up to tens of thousands of transportation fees is also good for him, for example, if he transports more than 100,000 pieces of winter clothes, it will definitely be known, and the price of winter clothes will increase this year.

There is also a good relationship with some mercenary groups, and at the same time, the competitors on the mercenary group's side let down their vigilance, after all, Yan Tielong himself has a mercenary group, and he actually doesn't use his own mercenaries to protect the goods, which makes the mercenary group community think that the mercenary group formed by Yan Tielong is just playing.

In fact, Yan Tielong didn't want to let his mercenary group take over the winter clothes, but unfortunately his mercenary group now belongs to reconstruction, there are too few personnel, and he only accepts elites, and at the same time, considering the benefits of system points, he has to give up.

Of course, in order to transport winter clothes safely, Yan Tielong asked the Shitu Martial Arts Hall to send a hundred members to follow, after all, he was also worried that there would be an accident on the way of the transport team, and he didn't even report a message.

After dealing with the winter clothes, Yan Tielong took his fiancée to Xiaoyuyu Town to see if he could solve the fuel problem, after all, Xiaoyuyu Town is not far from Conch Boss City, and there is a large amount of timber on the side of Conch Boss City, and the last time he went to Little Fish Town, he heard that there was an open-pit coal mine in Conch Boss City, and if there was really a coal mine, it would solve the fuel problem.

When Yan Tielong and Arya arrived in Xiaoyuyu Town, they immediately felt that it was much warmer here than Shougett City, after all, this is the junction of temperate zones and tropics, and many people don't feel cold in thin long sleeves.

First of all, Yan Tielong told Princess Long Lias about the Battle of the Kingdom of Virtues Arena and the birthday of the Sword Master, after all, this information is very important to Princess Long Lias.

After listening to Yan Tielong's narration, Princess Long Lias asked about the information about Ciri Arya, after all, she knew the strength of Arya, since she could defeat Arya, then Siri Aigen's strength must not be underestimated.

The most important thing is that for some reason, Princess Long Lias's strength has been suppressed, and now she can only exert 80% of her strength, and she can't transform into a half-dragon state.

Of course, Yan Tielong didn't know that Princess Long Lias's strength was suppressed, but he still told the information of Ciri Agern in detail.

After listening to Yan Tielong's story, Princess Long Lias began to judge in her heart that there were six levels of chance, so she asked Yan Tielong to arrange the time for the competition, and when the time came, she would participate in person.

As for the birthday of the Sword Saint, Princess Long Lias also expressed that she would participate, after all, the Sword Saint's birthday banquet is only good for the Wyvern Kingdom, and there is no harm.

After settling the matter of Princess Long Lias, Yan Tielong asked Princess Long Lias about the coal mine.

However, Princess Long Lias asked Yan Tielong about the coal mine, and she said that she did find a coal mine on the side of Conch Boss City, but the use of coal will produce toxic substances, and many people have been poisoned by using coal mines, and there is a lot of wood in Conch Boss City, and now they have switched to wood.

Hearing Princess Long Lias's story, Yan Tielong did not realize that there were other toxic minerals in the coal mine, which was also because Yan Tielong had already returned the knowledge about coal in the previous textbook to the teacher.

When Yan Tielong learned that someone had been poisoned by coal mines, he was puzzled and said that he wanted to see those coal mines.

Princess Long Lias asked Yan Tielong to see the coal mines, and she asked her subordinates to take Yan Tielong to see those coal mines, after all, those coal mines occupy a lot of space.

Led by a member of the Crystal Flower Knights, Yan Tielong came to the coal mine storage area, and at the same time, he also found out from the members of the Crystal Flower Knights that the coal mine here was 600 tons.

Yan Tielong took a piece of coal from a pile of coal mines and used the identification technique to see what the situation was, and through the identification technique, Yan Tielong found that the coal here had other substances, and they were all toxic substances, which also made him understand why Princess Long Lias gave up these coal mines.

Knowing the situation of the coal mine from the identification technique, Yan Tielong doubted in his heart that there was no poisoning in the use of coal in another world, so there must be no knowledge, so he asked how the system could reduce or eliminate harmful substances in the coal mine?

After Yan Tielong spent a thousand points to ask for a fee, the system told Yan Tielong a variety of plans, of course, there are many plans that cannot be completed with human world technology, but the system also told Yan Tielong that is very suitable for cleaning up toxic substances in coal in this era, and this method is coal washing.

So Yan Tielong spent nearly 100,000 points to change the coal washing plan, and after changing the coal washing plan, Yan Tielong felt regretful, because he thought that the coal washing method was very simple and not worth 100,000 points at all.

Already knowing how to reduce toxic substances in the coal mine, Yan Tielong asked the members of the Crystal Flower Knights around him to gather labor to wash the coal, and if the effect was good, he planned to use the system to make briquettes and burn briquettes iron furnace.

According to Yan Tielong's method, soon more than a dozen laborers washed out more than a dozen catties of coal mines, and then Yan Tielong used fire magic to dry them, and then used them to light them to see the effect.

And Yan Tielong had just ignited the washed coal, so the laborers subconsciously stayed away, after all, they knew about the death of coal poisoning.

Through the test, Yan Tielong found that the coal washed according to the system can definitely remove most of the toxic substances, so he ran to Princess Long Lias, he wanted to cooperate with Princess Long Lias to sell the coal mine, after all, Yan Tielong wanted to maximize the benefits of the plan exchanged for 100,000 points.

After learning that Yan Tielong had found the removal of toxic substances from the coal mine, Princess Long Lias of course agreed to cooperate in the coal mine business after seeing the physical effect, after all, the current Princess Long Lias is also a good thing for them.

Of course, Princess Long Lias negotiated with Yan Tielong on behalf of the fifth brother about the interests of the coal mine, which may make up for Yan Tielong's previous kindness to save the fifth prince, and use Yan Tielong's technology to share the five layers of benefits.

In the face of Yan Tielong's order of 200,000 gold coins, Princess Long Lias thinks that Yan Tielong has bought too much, after all, the cost of a kilogram of briquettes is less than two copper coins.

Yan Tielong said that now that the weather in the north is colder than in previous years, it may not be enough to support Leopais, let alone the wealthy Zhandes Kingdom.

Hearing that Yan Tielong was going to sell the coal mines to the Zhandes Kingdom, Princess Long Lias immediately decided to open up the land with Conch Bos City, so that more boats could fish, otherwise letting a large number of ships transport coal may cause a shortage of food on her side, after all, hundreds of thousands of refugees have gathered in Xiaoyuyu Town.

Princess Long Lias suddenly thought of something, and she asked her subordinates to prepare a seafood feast for Yan Tielong to taste.

Seeing the seafood, Yan Tielong suddenly thought of getting food for Leo Pine, so he expressed his gratitude to Princess Long Lias for his kindness in inviting him to a seafood feast, and then went to Liuxi Trading Town alone, after all, Arya now wants to catch up with her father.

When Yan Tielong came to Liuxi Trading Town, he saw that the residents of Liuxi Trading were repairing the destroyed town.

Yan Tielong quickly found the Qingyuyi people in charge of Liuxi Trade Town, and he informed the Qingyuyi people in charge of Liuxi Trading Town that he wanted to buy a large amount of food.

The Qingyuyi people in charge of Liuxi Trading Town showed an embarrassed expression, in his words, they did have a lot of food in Qingyuyi, but because of the epidemic, they were now very short of harvesting labor.

Hearing that the person in charge of Qingyuyi said that there was a great shortage of harvesting labor, Yan Tielong said that they were willing to bring some people to help.

Faced with the Sky Brave to help, the person in charge of Qingyuyi said that Yan Tielong and they couldn't help, because the food they grew in Qingyuyi had to be harvested by them, after all, in order to ensure that their fields were not eaten by other insects and animals, they put very dangerous insects in the fields.

However, the person in charge of the Green Feather Wing Clan also told Yan Tielong that their Green Feather Wing Clan had developed an antidote to the Wingfall Plague, so in the near future, someone from the clan would be responsible for harvesting it, so Yan Tielong would wait patiently for a few days.

Knowing that the Green Feather Wing Clan was going to harvest grain in a few days, Yan Tielong directly said goodbye, and then went to Shougett City to find Leo Pine and report today's results to the other party.

Leopis looked at the coal in his hand, and he couldn't help but ask Yan Tielong if it could really burn for a long time and not be poisoned?

It turned out that Leopis also knew about coal mines, and he also knew that coal was poisonous, so he had to confirm it with Yan Tielong.

Yan Tielong said that the coal he washed had removed the toxins of the coal itself, so it was almost non-toxic, and of course he also reminded Leopis not to burn coal in a closed room, after all, burning coal in a closed room is easy to poison carbon dioxide.
