Without waiting for Chen Hongyuan, Zhang Zhixuan left the poisonous dragon's materials to Zhang Sidao, and then returned to Lushan with the Qingni bottle.
As soon as he came back, he immediately went to the Ten Thousand Snakes Cave. At this time, the Ten Thousand Snakes Cave had already changed drastically after more than a year of transformation by Zhang family monks.
The cave of this cave has already been widened by the Zhang family monks.
The depths of the cave can already accommodate six people walking side by side at the same time. Every few dozen feet, a torch is lit, illuminating the cave as if it were daytime.
The gravel and remains of snakes and insects in the cave have long been cleared away, and even the walls have been swept spotlessly.
Zhang Zhixuan came to the underground river and found the clan leader meditating on the edge of the underground river.
Seeing that Zhang Zhixuan had come back, Zhang Leqian said with a smile: "Zhixuan is back. Did it go smoothly for you to go to Qingxuan Sect this time?"
"Thanks to the great blessing of the patriarch, I have lived up to everyone's expectations and got back the Qingni bottle from Aunt Hanyan."
"That's good. You've been away for the past few days, and I've been frowning. If the poisonous pool under the waterfall is not dealt with, it will not only be a hidden danger, but we will not be able to use the spiritual veins under the poisonous pool. .Now that you have the Qingni bottle in your hand, we can suck the venom from the poison pool into the Qingni bottle, and then use the alchemy furnace to make poison pills. Although this poison pool is not small in size, it only takes the three of us. By taking turns casting spells, one day we will be able to drain all the poisonous water from the poisonous pond."
The Qingni Bottle is a magic weapon that can absorb water-based venom.
This magical artifact is already a third-level mid-grade. It is mixed with some Kongming stones and possesses the laws of space. Although it is only the size of a palm on the outside, there is a space of three feet in diameter inside.
Although three feet of space is insignificant compared to the amount of venom in the Poison Pond, as long as the monks continue to absorb the venom, it will probably take less than a year to completely empty the Poison Pond.
Zhang Zhixuan and the three of them took turns using the Qingni bottle. Every time they used the Qingni bottle, they would inhale the venom in a three-foot radius.
In order to consume the venom, the Zhang family refined a huge bronze cauldron, poured the venom from the Qingni bottle into the cauldron, and used Xuanyang wood to refine it into poison pills.
This bronze tripod is made of hundreds of refined copper, and its grade is only first-class mid-grade. The Xuanyang wood cannot be produced by the Zhang family. This cost alone cost more than 300 spirit stones. .
Zhang Zhixuan and the three of them combined used Qingni bottles to absorb venom thirty times every day. It took four months to completely drain the venom from the poison pool.
In the past four months, the monks from the Zhang family went to Liucheng four times, purchased a large amount of Xuanyang wood from the Zhu family, and used cloud-walking beasts to transport it. It took countless manpower to refine the venom into a black poison ointment. .
The monks in the Qi refining stage wear special protective gloves, hold the best detoxifying pills in their mouths, and squeeze pieces of poisonous ointment into poison pills.
These poison pills are mixed with the venom of tens of thousands of extremely venomous snakes, which cannot be resolved without the use of precious antidote elixirs.
In addition to keeping some of this poisonous pill in the family, Zhang Zhixuan plans to sell it on a large scale in Xihefang and Heishan, at least to earn back the price of the bronze tripod and Xuanyang wood.
Once the venom in the poison tank is drained, the remaining poisonous snakes will be easier to deal with.
Although the Poison Pond was densely populated with a large number of poisonous snakes, it was a pity that the Zhang family monks threw huge amounts of wood into them and burned them all into coke.
When the fire was extinguished, the family's Qi Refining Stage monks took the mortals and carried all the ashes and remains out of the cave.
Even the mud under the Poison Pond, which was mixed with a large amount of highly toxic substances, was cleaned up, completely eliminating any hidden dangers.
In order to dig out these highly toxic sludge, the family also lost dozens of mortal soldiers, and even the innate monks in Lushan County lost two people.
After finishing all the debris, Zhang Zhi arranged a second-level spirit gathering array at the bottom of the Poison Pond and began to prepare to gather the spiritual energy in the underground river to facilitate the cultivation of the family monks.
After clearing the poisonous pond, Zhang Zhixuan opened the connection between the poisonous pond and the underground river a little, and reintroduced the water source from the underground river into the poisonous pond.
This spiritual vein, in a dark and dark environment, is somewhat similar to the Hanjiao Pond where the green dragon hid in the past. It is very suitable for large-scale planting of Xuanyou grass.
Nowadays, planting Xuanyou grass has become a very important source of income for the Zhang family. Some are also planted not only in the pool where the patriarch is recovering from his injuries, but also in the well in Lingjing Mountain.
More than twenty years have passed, and the three Xuanyou grasses that Zhang Zhixuan brought back from Montenegro have been harvested three times, and now they have expanded to more than twenty plants.
Unfortunately, the environmental requirements for planting spiritual grass are very high. There is not much space left in the two water pools suitable for planting Xuanyou grass. This time, the Wansheku water pool was discovered. According to the area and space of the spiritual energy intensity here, each crop can plant about
Seventy or eighty Xuanyou grass.
If these 70 or 80 Xuanyou grasses were all refined into Youhuan Dan, based on Zhang Zhixuan's current success rate in elixir refining, he would be able to refine approximately 500 Youhuan Dan.
Even if the quantity of Youhuan Dan increases on a large scale, the price has dropped to the same level as Black Mountain.
The price of fifty bottles of Youhuan Dan is about six thousand spirit stones. According to the average twelve-year growth cycle of Xuanyou grass, you can earn about five hundred spirit stones every year evenly.
In another twelve years, the Xuanyou grass planted in the water pool under the Ten Thousand Snake Cave will probably become a very important source of wealth for the family.
Moreover, in the past year and a half, the clan leader has discovered a fish spirit beast in this underground river.
This is a red, yellow and white carp fish spirit beast, called the three-color spirit fish. This kind of monster occasionally appears in the underground river, and in the past almost all of it became the food of poisonous dragons.
Although its taste is far less delicious than the Wu family's white-tailed reed fish, as long as you catch some and raise them, and open a shop in Xihefangzhong every year to sell them, you can earn dozens of spirit stones in hard-earned money.
After bringing in the living water from the underground river, Zhang Zhixuan sent someone to transplant a few Xuanyou grasses and plant them under the pool. Then he and the clan leader found a way to catch some three-color spirit fish and raise them in the middle of the pool.
In order to prevent the three-color spirit fish from swimming along the underground river, Zhang Zhixuan and others also weaved a magical fishing net at the mouth of the underground river.
It took almost a year and a half for the whole family to mobilize all the matters regarding Ten Thousand Snake Cave.
At this time, a small town had been built outside Ten Thousand Snake Cave, near the river. Thousands of mortals had moved into the town, and a large amount of farmland had been cultivated in the nearby valleys and plains.
The Ten Thousand Snake Cave is only seven or eight hundred miles away from Tiantai Peak, and a little further away from Lingjing Mountain, no more than a thousand miles away.
These three spiritual veins are like a triangle, enclosing all the nearby land.
The area within this triangle is the area of control of the Zhang family in Taicheng County. Within this area, the monks of the Zhang family can protect the safety of the mortals in the family.
There are no third-level spiritual veins here in Ten Thousand Snakes Cave, so there is no need for foundation-building monks to guard it for the time being. Zhang Zhixuan asked his eleventh uncle Zhang Menghong and a few young people to take charge of Ten Thousand Snakes Cave.
After everything was settled, Zhang Zhixuan was ready to send the Qingni bottle back to Qingxuan Sect and give it to Han Yan.
He flew all the way for more than ten days before arriving at the gate of Qingxuanzong. It had been half a year since he last visited Qingxuanzong.
Zhang Zhixuan first delivered the Qingni bottle to Han Yan, and then hurried back to Qingyangfang City to find Chen Hongyuan. .Full version
