Without waiting for Chen Hongyuan, Zhang Zhixuan left the materials on the poison Jiao 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, and at this time, after more than a year of transformation by the Zhang family monks, he had already changed his appearance.

The cave of this cave has long been widened by the Zhang family monks.

Deep in the cave, it can already accommodate six people side by side. Every dozen feet away, a torch was lit, illuminating the cave as if it were daylight.

The rubble in the cave, the remains of snakes and insects have long been removed, and even the walls have been cleaned spotlessly.

Zhang Zhixuan came to the underground river and found that the patriarch was meditating and cultivating on the edge of the river.

Zhang Leqian saw that Zhang Zhixuan had returned, and said with a smile: "Zhixuan is back, this time you went to Qingxuan Sect smoothly?" ”

"Patriarch Hongfu, I have lived up to expectations and retrieved the Qingni bottle in Aunt Hanyan's hand."

"That's fine. You're not here for a few days, and I've been frowning. This poisonous pool under the waterfall, if not dealt with, is not only a hidden danger, but also the spiritual veins under the poisonous pool, we can't use it. 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 Dan Furnace to refine it into a poison pill. Although the area of this poisonous pool is not small, as long as the three of us take turns casting spells, one day we will be able to drain all the poisonous water in the poisonous pool. ”

The Qingni Bottle is a magic weapon that can absorb the venom of the water attribute.

This magic weapon is already a third-grade medium-grade, mixed with some empty stones, with the law of space, although the appearance is only the size of a palm, but there is a space of three zhang square inside.

Although compared to the amount of venom in the poison pool, the three-zhang space is insignificant. But as long as the monk keeps sucking up the venom, I'm afraid it won't take more than a year to completely empty this poisonous pool.

Zhang Zhixuan and the three of them took turns to use the Qingni bottle, and every time they used the Qingni bottle, they would inhale the venom of the three-zhang space.

In order to consume these venoms, the Zhang family refined a huge bronze tripod, poured the venom from the Qingni bottle into the tripod, and used Xuanyang wood to refine it into a poison pill.

This bronze tripod is made of refined copper of hundreds of refinements, and the grade is only a middle grade, and the Xuanyang wood Zhang family cannot produce it, and this expense alone costs more than three hundred spirit stones.

Every day, Zhang Zhixuan and the three of them had to absorb the venom thirty times with the Qingni bottle, and it took four months to completely drain the venom in the poison pool.

In the past four months, the monks of the Zhang family went to Liucheng four times, purchased a large amount of Xuanyang wood from the Zhu family, and used the Cloud Beast to transport it, and it took countless manpower to refine these venoms into black poison ointment.

The monks in the Qi refining period put on special protective gloves, held the best antidote pill in their mouths, and pinched pieces of poisonous paste into poison pills.

These poison pills are mixed with the venom of tens of thousands of giant poisonous snakes, and they cannot be dissolved at all without using precious antidote elixirs.

This kind of poison pill, in addition to keeping a part of the family, Zhang Zhixuan is going to sell it on a large scale in Xihefang and Montenegro, at least to earn back the price of the bronze tripod and Xuanyang wood.

After draining the venom in the poisonous tan, the remaining poisonous snakes are easier to deal with.

Although there were a large number of poisonous snakes densely covered in the poisonous pool, it was a pity that they were all thrown into a huge amount of wood by the Zhang family monks and burned into charcoal.

When the fire was extinguished, the family's Qi Refining Stage cultivator took the mortals to transport all the ashes and remains out of the cave.

Even the sludge under the poison pool, because it was mixed with a large amount of poison, was also cleaned up, and the hidden danger was completely eliminated.

In order to dig out these highly poisonous sludges, the family also lost dozens of mortal soldiers, and even the innate monks of Lushan County also lost two.

After disposing of all the sundries, Zhang Zhi arranged a second-order spirit gathering array at the bottom of the poison pool, and began to prepare to gather the spiritual energy in the dark river, so as to facilitate the cultivation of the family cultivators.

After emptying the poison pool, Zhang Zhixuan opened the connection between the poison pool and the dark river a little, and reintroduced the water source in the dark river to the poison pool.

This spiritual vein, in the dark environment where you can't see your fingers, has some similarities with the Hanjiao Pond where the frogs hid back then, and it is very suitable for large-scale cultivation of Xuanyou grass.

Now planting Xuanyou grass has become a very important income for the Zhang family, not only the water pool where the patriarch is recuperating from his injuries, but also the well in Lingjing Mountain.

More than 20 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 20 plants.

It's a pity that the environment required for the cultivation of spiritual grass is very high, and there is not much space left in the two waterholes suitable for planting Xuanyu grass. This time, the Ten Thousand Snake Cave waterhole was discovered, and according to the aura strength area space here, each stubble could be planted with about seventy or eighty Xuanyu grasses.

These seventy or eighty Xuanyu Grasses, if all of them are cultivated into the Secret Returning Pill, according to Zhang Zhixuan's current success rate of alchemy, about five hundred Hidden Returning Pills can be refined.

Even if the number of Youhuan Dan increases on a large scale, the price has already fallen to the Black Mountain.

The price of fifty bottles of the Ghost Returning Pill is also around six thousand spirit stones. According to the average growth cycle of Xuanyu grass in twelve years, it can also earn about five hundred spirit stones every year.

In another twelve years, the Xuanyu grass planted in the waterhole under the Ten Thousand Snake Cave will probably become a very important source of wealth for the family.

And in the last year and a half, the patriarch has discovered a fish spirit beast in this underground dark river.

This is a red, yellow and white carp spirit animal, called the three-color spirit fish. This kind of demon beast occasionally appeared in the dark river, and almost all of them had become the mouth of the poisonous Jiao before.

Although its taste is far less delicious than the Wu family's white-tailed reed fish, as long as you catch some and raise it, you can also earn dozens of spirit stones by opening a store in Xihefang every year to sell them.

Bringing in the living water from the dark river, Zhang Zhixuan sent people to transplant a few Xuanyu grasses to the bottom of the waterhole. Then he and the patriarch managed to catch some three-colored spirit fish and raise them in the middle of the waterhole.

In order to prevent the three-color spirit fish from swimming along the dark river, Zhang Zhixuan and others also weaved magic fishing nets at the mouth of the dark river.

After all the matters in the Ten Thousand Snake Cave were dealt with, it took a year and a half for the family to mobilize almost the whole family.

At this time, outside the Ten Thousand Snake Cave, near the river, a small town had been built. Thousands of mortals have migrated to the town, and vast amounts of farmland have been reclaimed in the nearby valleys and plains.

Ten Thousand Snake Cave here, only seven or eight hundred miles away from Tiantai Peak, a little farther away from Lingjing Mountain, not more than a thousand miles.

These three spiritual veins are like a triangle, enclosing all the nearby land inside.

The range within this triangle is the control range of the Zhang family in Taicheng County. Within this range, the Zhang family monks would be able to protect the safety of the family's mortals.

There is no third-order spiritual vein in the Ten Thousand Snakes Cave, and there is no need for monks to guard it during the foundation building period for the time being, Zhang Zhixuan asked the eleventh uncle Zhang Menghong to take a few young people to sit in the Ten Thousand Snakes Cave.

After everything was settled, Zhang Zhixuan was ready to send the Qingni bottle back to Qingxuanzong and hand it over to Hanyan.

He flew all the way for more than ten days before arriving at the mountain gate of Qingxuanzong, and at this time, it had been half a year since the last time he went to Qingxuanzong.

Zhang Zhixuan first sent the Qingni bottle to Hanyan, and then hurriedly returned to Qingyangfang City to find Chen Hongyuan.
