When passing by the various halls, the sect disciples did not hesitate, and still jumped over and ran towards the back mountain. The disciples of the Four Extremes Sect also separated from each other at this time, and each headed to the mountain peak that had been assigned before.

Letong's team went straight to the main peak of the back mountain, and in a short time, they had reached the foot of the mountain. Only then did he slow down and start walking up little by little.

The weeds on the side of the road are verdant and lush, and there are some blooming flowers in between, so if mortals pass by here, they will probably think that this place is a paradise on earth. The disciples of the Four Extremes Sect began to pick some of the herbs they saw along the way, although these herbs were nothing in the strong period of this sect, but in the eyes of the current sect, they were quite valuable.

The higher you go, the steeper the mountain becomes, and a faint aura begins to float in the mountains. Everyone's muscles and veins began to accelerate involuntarily, absorbing aura, and the whole body was comfortable.

In this column, like a thirsty camel for many days, absorbing a large amount of aura from the mountains, not only that, the speed at which the white meridians absorb the aura is several times that of the meridians, and after absorption, there is no release in large quantities, but storage, and the white flocculent milk also begins to become thicker, and the original spots begin to condense to a piece, and repair the missing gaps.

After the human meridians are absorbed, they cannot be stored for a long time, most of them are discharged again with the metabolism of the body, and the white meridians are like a bottomless pit, which will store all the absorbed aura for a long time, and no one will be discharged outward. The higher he went, as the concentration of the aura began to increase, the absorption of the white meridians increased, more than ten times that of the others.

The higher they go, the slower the speed of the crowd's travel, on the one hand, to absorb the aura in the space, and on the other hand, the year of the herbs picked is also increasing, because refining the pill not only requires high-grade spirit grass, but also needs to be matched with some low-level spirit grass, so that the medicinal properties can be neutralized with each other and refined into a pill, which is extremely demanding for alchemists, so alchemists are a respected profession in various sects.

After arriving at the mountainside, a quaint courtyard was located on top of the mountain stream, and everyone began to put away the bags of medicinal herbs in their hands and enter the courtyard together. The yard is not very large, but it is indeed a two-entry yard. There are many roads leading to the mountain, and when the Four Extremes Sect goes, other sects are not following the same path, so only the people of the Four Extremes Sect are here on this path.

After entering the courtyard, several people instantly rushed to each house and began to look for it. Looking at the people looking around, Le Tong arranged for a few disciples to look for them in this courtyard, and then with Yan Duan, Zhang Yang and the two of them went towards the top of the mountain.

The road was unimpeded and reached the top of the mountain, where there were many dwellings and were already scorched. It seems that the children of other sects have already arrived here first.

At the end of the speech, Le Tong and Zhang Yang did not delay, and immediately walked towards the residence in and out, only to see that the house was simple and simple, except for a bedroom, there was nothing else.

Yan Duan rummaged through it, and there were some bottles and cans everywhere on the table in the room, and when he turned over some bottles and cans, it was dusty, which showed that no one had come in here for too long. After a while, after noticing anything, the three of them left the place and went to another residence.

Time passed, and the three of them had already turned over four or five residences, but there was still no gain. Just as Yan Duan was rummaging through a residence, he saw three bottles on the wall of a bedroom, and he wanted to take the three bottles down to take a look, but when he got the second bottle, he couldn't hold them. So, twisting the bottle from side to side, I saw a secret door suddenly open on one of the walls, and a puff of smoke filled the room.

After the smoke and dust dissipated, the three of them looked at the dark room in a daze, and after glancing at each other, Yan Duan took the lead in stepping in, and it was empty, with only a downward staircase. Yan Duan walked down the stairs, followed by Le Tong and Zhang Yang. After walking about a hundred and ten steps, Yan Duan finally saw what was under the dark room.

This is an alchemy room, and there is also a huge Dan furnace in the middle of the room. On the wall next to it, rows of lattices were neatly arranged, and the herbs in the lattices had died, and at the slightest touch, they turned into powder.

After searching along the alchemy room, they found nothing else, and finally, the three of them stood towards the Dan furnace placed in the middle of the room. Yan Duan slapped the top of the alchemy furnace with a palm, and with a "hum~" sound on the top of the furnace, it instantly flew down from the alchemy furnace and covered the ground directly.

The three of them looked inside the Dan furnace, and six crystal clear pills were displayed in a circle in the Dan furnace.

"Runmai Dan~" Zhang Yang couldn't help but shout. Runmai Pill is of great value to the sect, and it is a healing elixir for repairing meridian damage. It can be said that even a sect like the Four Extremes Sect has only ten Runmai Pills stored, but now six Runmai Pills have been found here, which is really a fluke.

When Yan Duan saw the Runmai Dan, he was not moved, nor did he directly take out the Runmai Dan from the Dan furnace. In his space ring, there are also two Runmai Pills, which he has taken twice before, so although Runmai Dan is precious, it is still a little bit short of Yan Duan. It's just that...... , Yan Duan bowed his head and did not speak, but had some questions, but some were not clear.

Seeing that Yan Duan lowered his head and did not speak, Le Tong did not compete for the Runmai Pill, so he nodded in his heart. Then he stepped forward and took out the six Moisturizing Pills from the alchemy furnace.

"Since there are six, let's follow the rules of the sect, except for the herbs that need to be handed over, the rest of the things belong to the individual, unless there are genius earth treasures or exercises and secrets. These six Runmai Pills, the three of us divide them equally, how about it?" Le Tong said as he looked at Yan Duan and Zhang Yang.

Zhang Yang nodded, and when he looked at Yan Duan again, Yan Duan didn't say a word. Le Tong originally thought that he felt that such a distribution was unfair, after all, he and Zhang Yang were both disciples of the fourth-level sect. But these belong to personal property and are not handed over, so Letong does not feel inappropriate in this distribution. After a few breaths, Yan Duan still hadn't answered, and Le Tong felt a little uncomfortable.

Just as Le Tong was about to step forward to talk to Yan Duan, Yan Duan suddenly raised his head and stared straight at the alchemy furnace. Le Tong and Zhang Yang stared at Yan Duan a little strangely, as if their souls had been affected.

The next scene was even more incredible. Yan Duan came to the side of the alchemy furnace, shot again, and punched towards the compartment of the Dan furnace that was showing a moist vein. "Bang~" sounded, and the compartment instantly scattered in all directions, and the black hole in the alchemy furnace couldn't see anything clearly. Yan Duan touched the ground on tiptoe and jumped into the alchemy furnace in an instant, and after a while, Yan Duan jumped up from the alchemy furnace again.

I saw Yan Duan holding a fist-sized black stone in his hand, as well as a few small broken stones. It is said to be a stone, but it is not like a stone, and there is a glimmer of light shining inside.

"Go get some water" Yan Duan looked at Zhang Yang and said with a serious face.

Zhang Yang turned his head to look at Le Tong, saw Le Tong nodded, and then walked out of the alchemy room, and after a while, he brought a bucket of water in. Yan Duan put a few stones in the water to wash them, and the more they were cleaned, the brighter they became. After the stone was cleaned, Yan Duan took it out of the water.

"Black Crystal~" Le Tong and Zhang Yang instantly lost their voices.

There are several ways to advance to the Grandmaster in the Qianyan Continent, one is to rely on one's own cultivation to mention the Grandmaster, the second is to take the Raw Xuansheng Spirit Fruit or the Snake Dragon Fruit to increase the probability of breaking through the Grandmaster's Land, and the third is to break through directly through the Lingxuan Pill, but the Xuanling Pill can rarely be found in the Qianyan Continent, and the other is to absorb the essence of the black crystal in the middle of the earth through the help of the black crystal, and break through to the Grandmaster realm.

But he didn't expect that the black crystal was in such an alchemy furnace. If it weren't for Yan Duan's awareness, it would be difficult for them to discover the existence of the black crystal, and then they would have missed the opportunity to become a grandmaster in vain.
