Except for Liu Yun, most of the alchemists in Yuanzong were older, and after returning to the sect, they had an unconcealable exhaustion on their faces.

After they saw Lin Xiu in the alchemy room, although they were a little surprised, they didn't say much, and went back to their own rooms to rest.

After the group of alchemists left, Liu Yun quietly lowered her voice, and said to Lin Xiu: "Junior brother Lin, do you know why my alchemist from Youlan Valley left the valley?"

Lin Xiu shook his head, how could he, an outer disciple who had just entered the mountain, know about the Youlan Valley.

Seeing Lin Xiu's puzzled look, Liu Yun covered her mouth and smiled, the youth at this moment was really touching.

She looked at Lin Xiu with some pride and said, "The Zongmen received news that a lot of rare elixir was found in a place in Guiyuan Domain, and among them was the very precious Tianxin Grass."

After so many days of sorting various elixir, Lin Xiu had already been familiar with the contents of the elixir treasure book.

This Tianxin Grass is the main medicine for refining Tianxin Pill.

If a cultivator at the Bone Tempering Realm wants to break through to the Spirit Fusion Realm, he must accommodate the spirits in the world, but that's easier said than done.

And Tianxin Pill is a kind of panacea that can increase the compatibility between a warrior and the wonders of heaven and earth. If a warrior has Tianxin Pill, the chance of breaking through to the spirit fusion state will increase by 30%.

The preciousness of Tianxin Pill can be seen from this.

And in some small cities, the Spiritual Realm has already reached the peak of cultivation, that is to say, Gui Yuanzong, which has thousands of talents in one body, has so many masters.

In other places, the Fusion Realm is also a cultivation level that cannot be underestimated.

Even though Gui Yuanzong's strength is already very strong, the amount of Tianxin grass stored in the sect is not too much. The fact that so many Tianxin grasses were discovered by accident this time also made the high-level members of the sect attach great importance to it.

Therefore, after hearing the news, many alchemists in Youlan Valley sent out Liu Yun, who was the weakest, to stay in the valley to ensure nothing would go wrong.

Looking at the exhausted looks of these alchemists, one can imagine how much effort they have spent these days.

You know, every alchemist's spiritual power is very strong. When refining alchemy, because it is necessary to precisely control the ratio of various elixir and the temperature of the fire, it is impossible for those who are not mentally strong to become an alchemist.

But even so, everyone still looks so tired, which shows that this action will definitely not be so easy.

The sky fell and there was a tall one, Lin Xiu didn't think much about it, these are not things he can handle now, but Liu Yun's next sentence caught his attention.

Seeing that Lin Xiu wasn't so shocked, Liu Yun raised her voice slightly.

Before you entered the sect, the suzerain once said that if you, the outer disciples who have just entered the mountain, can rank among the top ten in the combat power test three months later, then each of you will be able to obtain a heavenly heart Dan.

Lin Xiu's heart suddenly became hot. He has now reached the Bone Tempering Realm, and he is not so far away from the Spirit Melting Realm. The effect of Tianxin Pill on him is not small.

Having figured this out in his heart, Lin Xiu's eyes flashed with longing. Unlike others, he urgently needs to improve his cultivation quickly.

Although Lord Fenghuo helped Lin Zhong temporarily suppress the injury before, it can only last for five years.

In short, Lin Xiu needs to break through to the Tianyuan Realm within five years, so that he can be sure to help Lin Zhong recover completely.

But how could the Tianyuan realm be so easily achieved? In the entire Guiyuan Sect, the sum of the seven veins is only a few tens of Tianyuan realm, and on average, each vein has less than ten Tianyuan realm.

If others know that Lin Xiu's goal is so lofty, many people will surely laugh at him for being overconfident.

Under normal circumstances, Gui Yuanzong's outer disciples can only be promoted to the Spiritual Fusion Realm within five years, and only a very small number of talented people can break through to the Human Yuan Realm.

Wanting to complete the transformation from Bone Tempering Realm to Tianyuan Realm within five years is tantamount to nonsense!

But Lin Xiu got the opportunity given to him by the old man, and even got the Wangjiang Sword and the mysterious red bead in the inheritance place of Nether Palace.

Although Wangjiang Sword cannot be easily exposed because of being in Guiyuanzong, otherwise it will bring some unnecessary troubles to himself, but the mysterious Chizhu is transforming Lin Xiu's body all the time.

It can be said that Lin Xiu's strength is improving steadily every minute and every second, coupled with Master Fenghuo's guidance, he can avoid detours on the road of practice, and save a lot of time invisibly.

But even so, it is still very difficult to break through to the Tianyuan realm within five years.

If you want to achieve your goals, you must work harder than others. For this reason, in the battle power test three months later, Lin Xiu must try his best to reach the top ten in the battle power list of the Bone Tempering Realm, thus entering the ranks of inner disciples.

As long as he can enter the ranks of inner disciples, he will be able to receive vigorous cultivation from the sect, at least before he breaks into the spiritual fusion state, he no longer has to worry about resources.

Lin Xiu is now running a race against time every minute and every second.

Silently clenching his fists, Lin Xiu's face was brimming with fighting spirit again, and the rays of the setting sun reflected on Lin Xiu's body through the window, making the young man at this moment look extraordinarily full of vitality.

"Many alchemists in the valley just came back today, in order not to disturb their rest, you should go back earlier." Liu Yun said with some empathy.

Although she didn't know that Lin Xiu's ambitions were so lofty, but the second time they met, she directly stated that she lacked spirit stones, which was enough to prove that Lin Xiu was actually a cultivator at heart.

After thanking Liu Yun, Lin Xiu stepped out of the small building and wanted to go back to his residence to practice.

"Starting tomorrow, you can come to the small building once every three days. There are many alchemists here, and the work you have to do will actually be a lot easier." Liu Yun's faint voice came from behind, and Lin Xiu couldn't help revealing With a smile, Senior Sister Liu is a kind person.

Time passed quickly, and two months passed in a blink of an eye.

In the past two months, Lin Xiu fell into a crazy practice. He not only used up all the spirit stones on his body, but also borrowed a lot from Liu Yun.

And in the past two months of cultivation, Lin Xiu has made great progress. Anyone who is now has the possibility to pierce the membrane in the middle stage of the Bone Tempering Realm, and thus step into a new world.

And his physical body has also become more extraordinary with the double-sided assistance of the thousand-layer body training formula and the red bead. It seems that there are not many muscles in his slender figure, but there is a powerful energy hidden in the flesh and blood.

Compared with his cultivation base, his physical body is now stronger.
