Dear Lingshi

Song Yi was naturally delighted with Lu Yunsheng's action and gave him the alchemy furnace, and Ge Gang would not refuse Lu Yunsheng's request.

Refining Qi and Blood Pills is simpler than imagined. In addition to the flesh and blood of monsters, three auxiliary medicines are also needed, namely Soul Locking Grass, Blood Vein Flower and Black Crystal Grass.

Along the way, Lu Yunsheng collected quite a few Soul-Locking Grasses and Blood-Veined Flowers, but he had not seen the Black Crystal Grass yet.

However, Lu Yunsheng was not in a hurry, because it was even more dangerous in Nanshan at night. For safety reasons, he planned to find a quiet place to start practicing.

Not long after, Lu Yunsheng found a cliff not far away. He immediately used his natal flying sword to carve out a temporary cave on it.

After entering the cave, Lu Yunsheng casually set up a restriction at the entrance to conceal the breath. Most cultivators know this kind of restriction and it is very convenient to use.

This restriction was what he learned in the past two months. In order to enter Nanshan to search for the Xumai Grass, Lu Yunsheng also made a lot of preparations.

Just as Lu Yunsheng sat down cross-legged in this stone cave, he took out a piece of blue fire steel with blue and white flames from his storage ring, and began to use the secret Dantian sword-forging method to temper his natal flying sword.

Adding a little bit of this blue fire steel when refining a magic weapon can strengthen the connection between the cultivator and the magic weapon. It is also a treasure mine that most sword cultivators dream of.

At that time, when Hou Xuetong and his group were building the Duobao Pavilion base on the ruins of the Ye family mansion, they accidentally discovered the Ye family's treasure house.

When the treasure house was opened, it was filled with countless rare treasures. The blue fire steel was found in this treasure house.

In addition to this blue fire steel, Hou Xuetong and his companions also discovered many other precious minerals, such as the Qingxuan Stone that can remove impurities from magic weapons, and even more than three kilograms of precious Taiyi refined gold.

You should know that the two taels of Taiyi Jingjin that Lu Yunsheng encountered at the auction were sold at a sky-high price of 200,000 medium-grade spirit stones.

After these treasure mines were counted, recorded, and entered into the treasury of Duobao Pavilion, there were only more than ten days left since Lu Yunsheng set out.

Therefore, when Lu Yunsheng obtained these precious minerals, he did not use them immediately in order to accompany Bai Yushuo. At this time in Nanshan, it was not suitable to travel at night, so he could use these precious minerals to temper his flying sword.

Lu Yunsheng had thought about using Ye Nantian's Kunwu flying sword directly, but after he spent a lot of effort to successfully refine the sword, he found that the flying sword was awkward and even a little sluggish for him to control.

Finally, after asking, Lu Yunsheng learned from Shengyang that the sword cultivator's natal flying sword is different from ordinary magic weapons and spiritual tools.

This natal flying sword has been nurtured by the owner's true essence and soul for hundreds of years and has long been connected to the original owner's blood. How can it be easily controlled by others?

Unless Lu Yunsheng spends hundreds of years to erase all the marks left by the original owner on the flying sword.

Upon learning of this, Lu Yunsheng gave up immediately and had to try the secret method of Dantian sword-forging, hoping to refine the essence of the treasure mine contained in the flying sword into his own flying sword.

Unfortunately, this method still doesn't work.

Not only that, after Lu Yunsheng tried many times, he found that except for natural treasure mines, those spiritual tools and magic weapons that were refined into finished products were not feasible.

In desperation, Lu Yunsheng had to throw this top-grade magical Kunwu Flying Sword into his storage ring.

He couldn't use this natal flying sword, so naturally no one else could use it either, and it couldn't even be sold.

The top-grade magic weapon has completely turned into a pile of scrap metal.

Lu Yunsheng spent a night in cultivation. The essence of the blue fire steel was completely refined into his natal flying sword. Now he urged the flying sword to shuttle back and forth in the stone cave.

Sure enough, now the flying sword has become more easy to control. This not only improves the combat power in disguise, but also reduces the consumption of true energy when controlling the flying sword.

Lu Yunsheng put away his flying sword with satisfaction, then jumped out of the cave and continued moving towards the depths of Nanshan Mountain.

He had not run far when he found that the place looked more and more familiar. When he climbed over two more hills, the ingot-shaped valley suddenly appeared in his sight.

Revisiting the old place, Lu Yunsheng felt mixed emotions. He wanted to enter the Two Dharma Realms to see Master Chengqiu and the two little fish.

But he held back. He wanted to develop the two methods thoroughly before inviting Master Chengqiu out to give him a surprise.

Besides, his primary goal now is to find the Xuimai Grass. Uncle Hu can only hold on for less than three years. To be exact, he only has two years and ten months. He can't delay any longer.

Thinking of this, Lu Yunsheng suppressed the impulse in his heart and turned away.

Time waits for no one. As spring goes and autumn comes, the trees in Nanshan add another ring of growth.

During this year, Lu Yunsheng had no idea how far he had run in the Nanshan Mountains, but he still gained nothing. He had never seen any trace of the Xumai grass, nor had he found Xuan'er.

Seeing this situation, Lu Yunsheng was not only extremely anxious, but also mixed with some grief.

In order to save time, he later risked flying in the air deep in the Nanshan Mountains to search day and night.

The price of doing this was that he would often be chased around by Nascent Soul stage monsters. Fortunately, not only did he not become food for the monsters, but he also killed several Nascent Soul early and middle stage monsters.

As night fell that day, Lu Yunsheng landed on the top of a mountain while sighing.

At this time, only 50% of his true energy was left in his body. Since there was danger at any time in the depths of Nanshan Mountain, the remaining half of his true energy was used to fight the enemy or escape at any time.

Over time, after experiencing countless dangers, Lu Yunsheng also gained a lot of survival experience.

Whenever half of his true energy was left in his body, he would look for a safe place to restore his condition to its peak before continuing on his journey.

Two hours later, the sky had completely darkened. From the dense forest below the mountain, roars of beasts and even howls could be heard from time to time.

The monsters seemed to become more active at night. It was not a good time to travel now, but after Lu Yunsheng completely restored his internal energy, he resolutely continued on his journey.

Sure enough, when he had not walked far, his spiritual sense detected that ninety miles ahead there were three Nascent Soul stage monsters fighting each other.

No one knew where this place was in Nanshan, but Yuanying stage monsters seemed to be everywhere. In order to avoid trouble, Lu Yunsheng had to change direction.

Now Lu Yunsheng is searching aimlessly, and it doesn’t matter where he goes.

If you want to find Xumai Grass and Xuan'er, you can only rely on luck.

With a bit of luck, maybe the Euphorbia obesa would appear in the weeds at his feet the next moment, or maybe he would see Xuan'er after going around the foot of a mountain.

With this idea in mind, Lu Yunsheng walked forward while paying attention to his surroundings, and at the same time he was recording the path he had walked.

One is to prevent himself from getting lost, and the other is that he is afraid that he will search the same place repeatedly. After all, he cannot waste time anymore.
