The output of Huangyan Mountain Mine is very large, and the annual income can be two or three thousand, which is already the third largest industry outside Chaoyin Mountain and Xihefang for Taicheng County.

Now the strength of the Zhang family has been unique in Taicheng County, they have not changed the previous pattern of interests, and they only have a small number of interests in dividing the cake, and the income in Xihefang and Chaoyin Mountain is far inferior to that of the Wu family, and they have not even turned their faces with Zhu Liusu and other families.

Even the shares of the Lingshi Mine left by the Zhu family, the Zhang family was not moved, but gave it to Qingxuanzong according to the agreement.

Now that a mineral vein has finally been discovered and the cake has become bigger, Zhang Zhixuan is ready to monopolize this mine. The current Zhang family has enough strength to occupy this income, and other nearby families dare not complain.

Although Huangyan Mountain is a barren mountain, it is very close to Zhangjia Jiuhua Mountain, although there is a small family in the Qi training period nearby, but they do not dare to compete with the Zhang family for the ownership of Huangyan Mountain.

According to the tacit agreement of the Taicheng County family, this place was originally the Zhang family's sphere of influence, and even if others were hot, there was no excuse to meddle at all.

In order to take care of the situation in Huangyan Mountain, Zhang Zhixuan and Qingchan temporarily returned to Lingjing Cave Mansion, while Hanyan stayed in Black Mountain for retreat.

Now the country of Yu is relatively peaceful, there has been no war for more than ten years, because the location is remote, there are relatively few foreign monks, and the general environment is very safe.

Moreover, the garrison of Huangyan Mountain was very strict, and there were fourth-order puppet beasts guarding it, so ordinary casual cultivators did not dare to come to find trouble at all.

There was a safe environment outside, and Huangyan Mountain was soon on the right track, and a large number of forbidden god stones were mined. In order to make use of these forbidden god stones, Zhang Zhixuan sent Zhang Sidao to study with Zhang Shenglian, preparing to use the family's specialties to refine the forbidden god stones into magic weapons, and then sell them for a good price.

Zhang Shenglian is over forty years old, and her ancestors have no backers, but she has good spiritual roots and is also very talented in refining, especially good at refining magic clothes and brocade flags. Even if the cultivation is only the ninth level of Qi training, the alchemy technique has already reached the third order.

Originally, she was ready to exchange for Zhuji Dan Zhuji, but unfortunately she was not as shrewd as Zhang Zeqian in personality, and she was exchanged for Zhuji Dan first.

Shortly thereafter, the family changed the rules for exchanging Zhuji Dan, although Zhang Shenglian had a small savings, but it was still far from six thousand good deeds, even if her alchemy skills were good, she still needed to accumulate more than ten years.

Si Dao had been a third-order alchemist for eighty years, and after he lost the opportunity to go further on the path, he put his mind on improving his alchemy. A few years ago, he raised his alchemy technique to the third-order upper grade, and he had already caught up with his master Chen Hongyuan, even within the Qingxuan Sect, he was a well-known alchemist.

The two of them used the fire eye in Jiuhua Mountain to formulate many kinds of refining plans, and experimentally refined seven or eight magic weapons, but unfortunately they were still not very satisfied.

These magic weapons are somewhat deficient in design, and they also have many shortcomings after refining, and they can't compete with the same type of products at all.

Even if it is reluctantly refined, it is difficult to open up sales, unless Zhang Zhixuan engages in trade protection in Montenegro, and forcible promotion will have the opportunity to occupy a part of the market.

Just when the two were in trouble, Spider Mountain's Tonghuai helped the two solve big trouble.

It has been almost a year since the successful capture of the human-faced spider, and the domestication of the two human-faced spiders has entered the right track, and they have begun to spit out spider silk regularly.

However, this kind of demon beast has a ferocious personality, even if it is controlled by the beast order, it does not dare to be handed over to the monks of the Qi training period to take care of, whether it is feeding or collecting spider silk, it must be done by Tonghuai himself.

In order not to delay their cultivation, and the output of Huangyan Mountain was already considerable, Zhang Zhixuan was ruthless, and invested another 10,000 spirit stones to cultivate a third-order lower grade spirit vein in Spider Mountain for them to cultivate.

Now in Taicheng County, the Zhang family has developed five third-order spiritual veins, the underground dark river from the Ten Thousand Snake Cave to Lingjing Mountain, and there are still several spiritual veins that have not been developed, and one of them has reached the third order. These spiritual veins have all been developed, and the number of monks that the Zhang family can support will be doubled.

The distance in this area is not very far, even if it is a relatively remote Jiuhua Mountain, it is less than two thousand miles away from Lushan.

Although this distance is far from that for mortals, it is less than a day for a foundation building monk. Even for a relatively slow Qi cultivation period cultivator, the journey would not exceed three days, and if he rode the clan's Cloud Stepping Beast, the time could be shortened by half.

The spider silk of the human-faced spider is very tough, and the spirit veil woven from this spider silk can block the slashing of low-level flying swords. Although it is inconvenient to wear the refining vestment because there are too many burrs and it is not soft enough, it can perfectly smelt the forbidden god stone on the spirit veil, blocking the divine consciousness of the isolated monk.

After refining the forbidden veil, the family immediately made a screen, painted with exquisite patterns, and placed it in the family's major stores to advertise.

This kind of magic weapon can weaken the divine consciousness of monks, especially those of monks in the foundation building period, and it is almost half restricted.

For the monks who set up shops in Fang City, there will always be some secrets that they don't want people to know, and buying a screen like this is already a property that must be invested.

Except for the Huanshui Sect, the Yu State has a vein of forbidden god stones, and there are no resources in this area.

The Huanshui Sect used the forbidden god stone to smelt other materials to make a beautiful tile, which was very expensive and shipped in relatively small quantities, and was mainly used to build a cave for high-ranking monks.

In the past, Qingxuanzong had to purchase the same type of magic weapons from the Song Kingdom, and all they took out were precious spirit stones. Now that the Zhang family has the same type of magic weapon, if Qingxuanzong wants to use it, he can exchange it for the good deeds of the sect.

Although the good deeds of the sect are as precious as the spirit stones, they can be seconded to each other for turnover, and the Qingxuan Sect can also save working capital and invest the spirit stones in places where they are more needed.

With the support of Qingxuanzong, the forbidden god yarn refined by the Zhang family can be regarded as filling the gap in this area, and soon monopolized the financial resources in this area.

Although limited by the output of human-faced spider silk, the output of the forbidden god yarn is not very large, but the profit brought to the Zhang family is actually three thousand a year.

Coupled with the remaining part of the ore in Huangyan Mountain, although Huangyan Mountain and Spider Mountain have not opened up a single acre of spiritual field, the income that can be brought to the Zhang family every year has exceeded 4,000, which is equivalent to the second Lingjing Mountain.

Sidao and Sheng Lian, two refiners, made meritorious contributions to the invention of the forbidden god yarn, and Zhang Zhixuan rewarded them with 3,000 for their good deeds. The idea of refining the forbidden veil is relatively simple, and the time is relatively short, and the main credit should also be placed on the materials.

Zhang Shenglian had these three thousand good deeds, and immediately went to Montenegro to exchange for Zhuji Dan, she is a three-spirit root cultivator, and it has been ten years since she cultivated to the ninth level of Qi cultivation, and the process of retreat was relatively smooth, and she successfully broke through to the foundation building realm.
