Zhang Shan told Han Jin that it turned out that all the monks in the entire Firmament Continent traded with gold and silver coins as bargaining chips. One gold coin is equal to one hundred silver coins, whether it is elixir, spirit grass, weapons, or charms, they are all traded with them. What is scarce in the entire continent is the spirit stone, one hundred gold coins can be exchanged for a low-grade spirit stone, and a hundred low-grade spirit stones can be exchanged for a medium-grade spirit stone, and one hundred medium-grade spirit stones can be exchanged for a high-grade spirit stone.

Gu Ming thought that the aura of the lower-grade spirit stone reserve was not as pure and rich as the aura of the middle-grade spirit stone reserve.

In other words, a high-grade spirit stone alloy coin costs one million.

For him, who is in business, it is not difficult to make money, but it is a big deal to be worried about money.

"Senior brother, how do you make money?"

"You want to make money"?

Zhang Shan was stunned, and Han Jin disagreed: "What, isn't the sect allowed it?"

"That's not it, the sect is also advocated, you know, the cultivation world has always advocated martial arts, not to mention the sect, the sect is not like the Bulun City family forces, their way of survival is to survive with martial arts and merchants, and the way of survival of the sect is to specialize in martial arts in order to live forever......"

"Senior brother, I understand all this, so you can tell me what to do to make the most money now. ”

Zhang Shan thought for a while and said: "Earn money, in fact, you can earn anything, so let's do it, tomorrow I will walk with you in the nearest villages and towns, don't you know better, although I don't know what you want to do, I support you in my heart."

"Senior brother"?

Zhang Shan looked at Han Jin looking at him with affection, and asked in surprise, "What's wrong?"

"If you were a woman, I want to kiss you"!

"Get out"!

............

The next day, Zhang Shan and Han Jin asked their master for leave, quickly descended the mountain, and came to the nearby Tian'an Town a few days later.

Sure enough, as Han Jin thought, the buildings here are like the ancient Chinese period, a complete building structure system of Qin bricks, Han tiles and wooden structures......

Walking on the busy street, looking at all kinds of stall owners selling all kinds of items, Han Jin was really dazzled.

"Senior brother, have you seen it, as long as you have good things to sell at all, I will only take you to two places, one is the Chamber of Commerce here, there are two of the most famous, one is the Biyou Chamber of Commerce, the other is called the Oriental Chamber of Commerce, of course, we went to the Biyou Chamber of Commerce, and there is also a place, called the auction, every day is auctioning the top items that the monks need, of course, this is just a small auction. ”

Zhang Shan and Han Jin lived in Tian'an Town for three days, and during these three days, Han Jin learned about various 'routines', and also knew about the elixirs that were urgently needed or popular in Tian'an Town.

For example, 'Tsukidan' is worth at least 20,000 gold coins.

After returning to the sect, Han Jin decided to take the pill as the main direction of development first, and there were four problems in front of him first: first, refining a first-grade pill, which one was the best, that is, the best-selling one; second, where is the supply channel of the spirit grass, it is impossible for the sect to supply it; third, if he alchemizes, he must break through to the middle stage of qi cultivation before he can exert his true fire, how to break through; fourth, who will the seller deliver to? It is impossible to develop the channel by himself!

This night, Han Jin thought about it for a whole night............

The next day, Han Jin found Zhang Shan and asked him to help him do something.

Then Han Jin found a master alone and learned alchemy with him, but this old man didn't give him any face, saying that he couldn't cultivate at home, so he let him get out of here.

In the end, Han Jin came to the Scripture Pavilion.

"Elder, are there any books on learning alchemy?"

"Oh, want to learn alchemy"?

A very fat young deacon looked at Han Jin coldly.

"Yes, Disciple Alchemy Pavilion Elder Xue Muhai disciple, because the master has been very busy recently, there is no way but to study and study on his own."

"Hehe, it's really weird, okay, you go and take a look at the bookcase No. 53, there are a few books there, but if you really want to learn alchemy, you have to work hard to improve your cultivation, and there are also a lot of books on alchemy on the third floor of the Tibetan Scripture Pavilion, but you can't go to your cultivation level, so you can do it yourself"!

Han Jin walked to the bookcase No. 53, but he really found three books on alchemy, because he couldn't take them out, Han Jin could only find a corner and bury his head in reading.

Back at the Alchemy Pavilion, it was already very late.

"Senior brother, I've been waiting for you for a long time, here you go"!

Han Jin took the storage bag that Zhang Shan handed him, opened it and saw that all the Dan Grass and thirty Lower-grade Spirit Stones needed for the two first-level pill "Pure Heart Pills".

Han Jin couldn't help but smile, he was deeply tired, and his face was relaxed at this time.

Zhang Shan shook his head: "The two second-level spirit grasses 'Blue and White Green Leaf Grass' that my junior brother gave me, I can only find the safest way to get these, obviously we have lost!"

"Senior brother, this is already very good, then from tomorrow, I will start retreat and practice, bother the senior brother to bring a message to the master, and also, the senior brother will help me prepare a Dan furnace, thank you again after the matter is completed"!

Zhang Shan looked at Han Jin's back and quickly left, and said in a deep voice: "Senior brother, don't let me down!"

"What are you doing here"?

"Ah, master......"

.........

Han Jin returned to the cave mansion and began to attack the cultivation of the fourth layer of Qi training.

Han Jin, who had been sitting cross-legged for two days, was already covered with an aura of qi charm, the inner world true qi vortex was constantly running, and the spirit stones in his hands were also formed into pieces of fragments.

Finally, on the third day, Han Jin stopped cultivating: "I can't imagine that thirty-three lower-grade spirit stones can only allow me to stop practicing qi at the fourth level, I really don't know how those foundation building and knot monks survived, and it is really a cultivation without years." ”

Han Jin immediately used the fire control technique, and saw that the flames in his palms were extremely lush, and they were even hotter than the flames in the early stage of qi training.

"I don't know if I got the Dan furnace?"

This is what Han Jin is most concerned about, but Zhang Shan did not veto, so there should be no problem.

Han Jin left the cave mansion and went to the Alchemy Pavilion.

His plan is very simple, even if he doesn't have a Dan furnace, he will use the master's Dan furnace.

"Nobody is there"?

No one responded, good sign!

Han Jin didn't say a word, sorted out the 'Qingxin Dan' formula spirit grass, checked the Dan furnace and cleaned it correctly, then released the real fire, waited until the furnace temperature rose, and according to the instructions of the Dan Fang, slowly put the spirit grass into the Dan furnace in order, and carried out the first step of alchemy, and liquefied the medicinal materials.

Maybe it was the first time to refine the elixir, and whether it was successful or not was a kind of exercise for him, so Han Jin seemed very calm, but he was also very serious, and he was even more careful in controlling the temperature of the flame, especially the purification of the liquefaction, which was even more dedicated.

After the time of the two pillars of incense, Han Jin felt that he was about to condense the pill, and he continued to increase his firepower with sweat all over his body......

"Yudan!"

The moment Han Jin put away the real fire, he almost collapsed and fell to the ground.

However, for the first alchemy was a success, how to be happy.
