The harvest in the demon python's underground lair is huge, and only four of the dozen and so plants are mature.

These four spirit grasses combined with some auxiliary elixirs can refine the four furnaces of Zhuji Dan.

In the hands of alchemists above the second order, each furnace can produce one to four Zhuji Dan, which is of great value.

Zhu Youdao had obtained the pill recipe of Zhuji Dan as early as in the alchemy inheritance harvested in the Great Holy Valley, and now he has alchemy materials, but unfortunately, although Li Yunniang, the only alchemist of the Zhu family, has a good alchemy talent, but he is limited to cultivation and can only refine the first-order spirit pill, and the Zhuji Dan is the most complex of the second-order spirit pills, and she can't refine it at all.

Even so, if you can find a suitable channel, you can exchange four Tsukidan for four Tsukidans.

However, the Dan masters who can refine the Zhuji Dan are all from big families, and once they are exchanged, they are afraid that they will trace the source of the Hidden Returning Grass, which may bring disaster to the Zhu family.

Therefore, this matter has to be carefully considered.

In the Demon Python Nest**, some refining materials were also found, although the value is not small, but it is nothing compared to the Hidden Grass.

There is also a natural first-grade spiritual vein in the underground cave, and Li Yunniang has arranged a set of magic circles to guide the spiritual veins here, so that the spiritual energy is exclusively for the growth of immature Youhui grass.

In order to prevent outsiders and other demon beasts from entering this place by mistake, Li Yunniang also arranged a magic circle outside the cave to hide and protect the cave.

After doing this well, the Zhu family and his party left here.

Zhu Yuanchang said: "The harvest of this trip is huge, we have been out for almost a year, it's time to go home!"

Zhu Youdao said: "There is another place, when I was surrounded by demon beasts here, I was rescued by a three-eyed spirit deer, after it rescued me, it pointed me to a small valley, where there is a magic circle to guard, but I probed for more than a month, but I didn't find the whereabouts of the monk, in order to ensure safety, I didn't enter the formation, and now Yun Niang is also here, and you can help, but you can go to explore the magic circle, see what secrets are inside!"

Everyone nodded yes, and under the leadership of Zhu Youdao, they headed towards the small valley.

After more than ten days of walking, I finally reached the outside of the valley.

Zhu Youdao checked carefully, but still found no signs of human activity outside the valley.

The strongest cultivator of the Zhu family array is Li Yunniang, followed by Zhu Youdao.

But Zhu Youdao took advantage of Youqing's eyes, and he may not be worse than Li Yunniang in breaking the formation.

The two watched in front of the formation for a long time, and Li Yunniang said: "The purpose of this array is to cover this small valley on the outside, and the phantom array is used, but there is a hidden killing machine inside, if you can't understand the changes in it, you won't be able to get out if you go in." In my estimation, this is at least the magic circle arranged by the Jindan period monks, and I can't break it!"

Zhu Youdao's eyes were blue, and he said: "I have seen through the nodes of this formation with my spiritual eyes, but I can't see through the changes in the formation! I will draw the magic circle, Yun Niang, you will deduce!"

Li Yunniang said excitedly: "If we can see through this formation, we will be able to see through it in some time!"

Zhu Youdao said to the others: "We are camped here, Xiaohong will take everyone to look around, and Yun Niang and I will study this magic circle." ”

Everyone nodded yes and started camping.

After the camp was settled, the magic circle was laid out, Zhu Youdao and Li Yunniang studied the mysterious magic circle in the camp, and the others went their own way.

The use of the Qing Ying Eye consumes a lot of mana, and with Zhu Youdao's cultivation, it can only be used for one hour a day. He spent an hour watching the changes of the magic circle, then drew a formation diagram, and then studied it with Li Yunniang.

Both of them had a strong interest in the magic circle, and they were addicted to it, and more than three months passed unconsciously.

Xie Xiaohong took a few other members of the Zhu family to explore the nearby area, hunted a lot of demon beasts, and collected a lot of spiritual objects.

On this day, Li Yunniang closed the thick manuscript of the formation diagram and said to Zhu Youdao: "I have studied it thoroughly, this array has a total of two hundred and twenty-five changes, which is cycled every seven days, and there are a total of fifteen main array eye ......!"

Zhu Youdao said: "I'm going to be almost, there are some joints that I haven't figured out, and when both of us have eaten thoroughly, we will break the formation again!

Li Yunniang nodded.

Zhu Youdao has never been afraid of losing face in learning, so when he encountered difficulties, he took the initiative to ask Li Yunniang for advice.

Five days later, Zhu Youdao also studied the magic circle thoroughly, confirmed it with Li Yunniang, and then recalled everyone, and then went to break the formation.

Zhu Youdao went to break the formation first, after all, his cultivation was higher than Li Yunniang, and in case of an emergency, he could support it for a while longer.

So the Zhu family and his entourage were preparing to respond outside the formation, and Zhu Youdao entered the formation alone.

Half an hour, Zhu Youdao came out of the formation: "I've encountered some trouble, discuss it with Yun Niang!"

He and Li Yunniang talked about the actual changes in the magic circle, and the two discussed it, and Zhu Youdao continued to go in to break the formation.

After another period of time, Zhu Youdao came out again, and after repeating this five or six times, Zhu Youdao finally passed the magic circle.

As far as the eye can see, there is a long and narrow valley, in which temporary caves have been built, and there are scattered tools at random.

Zhu Youdao picked up an axe and found that it was just a tool that had been simply refined with refining techniques, and it was not even a magic weapon. The wooden handle of the axe has rotted, and it has been a long time since I wanted to throw it here.

Zhu Youdao blessed himself with a protective spirit talisman and walked towards a cave mansion, where there was no one inside, and there were a lot of living materials stored, but because they had been stored for too long, all of them could not be used.

They searched the caves one by one, but found no valuable clues.

In front of the last large cave, it was found that a simple warning circle was arranged at the entrance of the cave, and this kind of magic circle was easy to break for any monk of the Zhu family.

When Zhu Youdao entered the cave, he saw the bones of a monk sitting on the stone platform, with a storage bag beside him, and a jade slip next to the storage bag.

Zhu Youdao grabbed the jade slip with his mana, checked it with his divine sense, and saw a piece of information left inside:

"I, Wang Deyuan, live in Yunzhou Eagle Sorrow, am the eldest grandson of the Wang family, and I am valued by the elders of the family, and I am designated as the person who will succeed the patriarch......"

Zhu Youdao was shocked in his heart, it turned out to be a member of the Eagle Chou Jian Wang family, and he was the young patriarch of the Wang family!

He had heard a rumor that was widely spread in Yunzhou, and it was said that the Eagle Chou Jian Wang family was once the strongest Jindan family in Yunzhou, and there were five or six Jindan monks in the family. Three hundred years ago, one of the Jindan ancestors of the Wang family broke the pill and became a Yuanying monk. But then he was found by the three old monsters of the Zhou clan in Vientiane, and destroyed the Wang family on the charge of colluding with the demon monks......

But the Wang family was wiped out by the Vientiane Zhou clan, how could their young patriarch die here?

With such doubts, Zhu Youdao continued to read......
