After discussing with Nalan Su, Nalan Yanran received tens of thousands of gold coins from Nalan Su's private sponsorship, and at the same time, she also got a promise that she would secretly hand over the mineral resources of a place in the future of Nalan Su's hand to Nalan Yanran every month.

Regarding this opportunity to trade freely, Nalan Su said that he would test the water first, after all, business activities are more about losses than profits. So I won't invest too much in the early stage, these are just for Nalan Yanran to test the waters.

But even so, Nalan Yanran knew that this was an opportunity to make a lot of money. After all, during this time, she had encountered a lot of stall holders from the technological plane, and bought a large number of metals from other planes.

And the mineral resource that Nalan Su handed over to her happened to be a metal mineral, ice rock iron. According to the mining speed of the Nalan family, they can get tens of millions of catties, nearly 10,000 tons every month. That's a lot of stuff.

As long as the price is right, you can make a lot of money.

As for the tens of thousands of gold coins given by Nalan Su, you can also find those who are in the high-level world to buy some low-level heavenly and earthly treasures in their world, which can not only be used by yourself, but also benefit the family. Of course, the things that benefit the family have to wait until she becomes a real powerhouse, otherwise, without the protection of a real powerhouse, the Nalan family, which has a great opportunity, will be targeted by other forces.

Nalan Yanran came out of Nalan Su's study directly, and couldn't wait to return to her room and start reading the content of the exercises.

Cultivating the exercises, this is a big deal. A fighter who has just broken through is not even a one-star fighter. Only after cultivating the exercises and completely transforming the attributed fighting qi can he be regarded as a one-star fighter.

In the next few days, Nalan Yanran was studying this volume of exercises in addition to her usual daily life.

After the exercises were thoroughly understood, Nalan Yanran began to transform the exercises.

The first transformation of Dou Qi would not take too long, so just two hours later, Nalan Yanran, who was sitting cross-legged, slowly opened her eyes.

After practicing the Dou Qi Gong Method, Nalan Yanran seemed to be more energetic than before, and her beautiful face was glowing with a little bit of warm jade-like luster, and she looked even more beautiful.

Stretching out his white palm, the cyclone in Nalan Yanran's body, which had turned into a pale yellow whole, quickly flowed out a light yellow fighting qi, and finally stopped at the acupuncture point in the palm.

The Dou Qi is released, that is at least something that can only be done by a Great Dou Master, and the current Nalan Yanran obviously does not have this kind of strength, so the Dou Qi in the body has not broken through the blockage of the acupuncture points, but on the white palm, it gradually flashes a little cyan light, the light does not seem to be very obvious, but it is meager but not dim.

Cyan, the symbol color of the Xuan-level Intermediate Wind Attribute Exercise, the higher the level of the Dou Qi Technique, the darker the color.

The wind attribute exercises of the yellow rank belong to light cyan to light cyan, while the wind attribute exercises of the Xuan rank are cyan, Nalan Yanran above the ground level doesn't know, it is estimated that it should be dark cyan or ink, right?

After transforming the exercises, Nalan Yanran completely entered the realm of fighters and became a real one-star fighter.

Clenched her fists, Nalan Yanran felt the fighting energy in her body surging again after cultivating the exercises, and she was also quite puzzled in her heart.

You must know that the ninth stage of Douzhiqi, even if it is at its peak, its fighting qi is only one-tenth of when it has just broken through the fighter.

The realm that can be broken through in these few hours has increased for himself several times closer to the fighting spirit that he had only had in years of penance before. What is this? Only in the state of breakthrough can you quickly refine the energy of heaven and earth?

There is also the transfer cultivation method, according to the knowledge of the Dou Qi Continent that I have learned, there is a gap of two or three times between the Xuan Rank Intermediate Exercises and the Yellow Rank Intermediate Exercises on the blessing of Dou Qi.

So how did the fighting spirit in his body that had skyrocketed several times again appear in just one or two hours?

If you switch to the Yellow Rank Intermediate Technique again, can you use the extra fighting energy to advance a few stars again?

"Sure enough, the technology side and the fantasy side are not the same concept at all. With the scientific knowledge learned on Blue Star, it really couldn't explain the various things in the Douqi Continent. ”

Nalan Yanran shook her head, if she can't think of it, she won't think about it, this thing is estimated that anyone who has come into contact with the Heavens Trading Center and similar existences will encounter it, maybe you can ask the Heavens Trading Center when you are free in the future. But there's no need, as long as you can get stronger.

After completely transforming the fighting spirit, Nalan Yanran took out the Zhu Guo that was still stored in the Na ring, and after thinking about it, she still ate it directly, and then sat cross-legged on the bed to refine the medicinal power.

………

A few days later, Nalan Yanran, who had already cultivated to a three-star fighter, received the first batch of ice rock iron ore given by Nalan Su.

Glacial iron ore is a peculiar metal mineral. The refined Ice Rock Iron has extremely high conduction properties of Ice Attribute Dou Qi and Earth Attribute Dou Qi, so many Ice Attribute and Earth Attribute Fighters will use this metal to make weapons, which can exert stronger power.

However, this thing is quite hard, and a fighter's punch after using a fighting skill will completely shatter ordinary stones, even iron ore, which will produce deep cracks.

But this metal is very hard when it is still ore, and it can only be mined by people in the realm of fighters, even with tools. Therefore, the yield is relatively low.

Moreover, because its smelting temperature requires a fire attribute cultivator of the Dou Master and above to smelt it for half a day before it can be melted and then purified, so in the Gama Empire, although there are a lot of reserves, few people are willing to mine them. After all, in the world of fighters, this thing is purely dispensable.

Nalan Yanran held the ring that Nalan Su had just given her in her hand and entered the Heavens Trading Center.

The density of ice rock iron is very high, even if it is only in the state of ore, its density is more than 13,000 catties per cubic meter, and if it is refined, one cubic meter of pure ice rock iron is close to 40,000 catties, that is, 20 tons of weight.

Therefore, tens of millions of catties of ore per month are less than 1,000 cubic meters, and a high-grade ring can be solved.

Nalan Yanran took this ring and teleported directly to the stall that she encountered that time to buy strange metals, and then had a series of bargains with the stall holder from the scientific and technological immortal cultivation plane, and then bought ice rock iron at the price of one gold coin per catty, and ten million catties of ice rock iron is tens of millions of gold coins.

Although half of it was about to be swallowed by the Heavens Trading Center, Nalan Yanran also got more than five million gold coins. Five million, not to mention the ore of this ice rock iron, it is the metal after refining, and there is no high price of a gold coin in the Douqi Continent, and it can be sold for a silver coin per catty. As a result, in the Heavenly Trading Center, this price has increased many times.

Five million gold coins, this is the income of the Nalan family for several years. You must know that she is the eldest lady, and her pocket money for a year is only a few hundred gold coins, and she has saved for so many years and borrowed some from other people to make up a few thousand gold coins. That's a lot of money.

"I didn't expect that this month's ice rock iron ore would be exchanged for a roll of low-level exercises." Nalan was amazed.

The Xuan-level high-level exercises are generally at the price of hundreds of thousands of gold coins, while the low-level exercises of the ground level, although they are not sold in the Gama Empire, if they are in some places such as the Black Horn Domain or Zhongzhou, it is only a few million.

And she actually made so much money in this breath.

"With so much money, it looks like I can buy some nice things." Out of the stall where the metal was purchased, Nalan Yanran began to wander around the trading center to see if she could find some goods she liked.

After all, I made so much money, and I just spent it. Otherwise, how to improve the strength?
