Jiang Xincheng went directly to the garden near the south gate of the school, and after looking for a while, he dug up with the shovel he had prepared.

Maybe in the eyes of ordinary people, the soil dug out by Jiang Xincheng is very ordinary, it is everywhere in the world, and people don't even look at it, at best, this kind of soil is still a kind of yuan stone, a first-class and low-grade yuan stone, and the current earth yuan stone can't be used at all.

However, in Jiang Xincheng's opinion, these clay yuan stones were excellent materials for refining the first-grade lower grade pill Houtu Dan, because there was an osmanthus tree growing on this clay yuan stone.

The osmanthus tree is a precious spiritual grass, which contains a huge yuan power comparable to the sixth-level high-grade yuan stone, and the elixir refined from the osmanthus tree can not only improve the yuan power, but also have the effect of calming the nerves.

In the previous life, with the development of alchemy, the osmanthus tree gradually became a precious treasure, and the price of an osmanthus tree reached more than 10 million yuan at the most expensive time, and even so it was still in short supply.

But now, because alchemy has not yet appeared, although the humans on the earth know that the osmanthus tree is a very useful spiritual grass, no one can use it, and they can only stare at the osmanthus tree trunk.

However, Jiang Xincheng could only stare at the osmanthus tree trunk now, his alchemy technique was too low, and he couldn't use the precious spiritual grass of the osmanthus tree at all.

Although he couldn't use the osmanthus tree and couldn't refine the priceless sixth- and seventh-level elixirs, Jiang Xincheng was able to use the soil under the osmanthus tree to refine the elixir.

Because of the long-term contact with the osmanthus tree, these soil stones are also contaminated with the fragrance of some osmanthus trees, and over the years, they gradually transform into a low-level spiritual grass.

This kind of spiritual grass was called osmanthus soil in previous generations, and it was an excellent material for refining thick soil pills.

After digging a sack of osmanthus soil, and finding some locust leaves, camellia, mulberry leaves and other spiritual grasses, Jiang Xincheng took all the spiritual grasses for refining Houtu Dan and returned to the rented single room.

The earth is now full of spiritual herbs and elixirs, and no one will take a second look, let alone pick them.

Jiang Xincheng's process of collecting these materials couldn't be smoother, like in his previous life, with the popularization of alchemy, all kinds of spiritual grasses on the earth were swept away, and it was simply a fool's dream to make enough materials for refining the spirit pill by himself.

But now, in just half a day's effort, Jiang Xincheng has obtained a spirit grass that can refine dozens of Thick Earth Pills, and no one has robbed him yet, let alone anyone who has not hesitated to kill people and rob money in order to seize the spirit grass in his hand.

This kind of world is really beautiful, and it feels even better to be able to walk in front of the world's Yuanshi.

After returning to the single room, Jiang Xincheng bought some coal and came back, preparing to use coal to make a fire and refine Houtu Dan.

Looking at the coal piled up in the corner of the room, feeling the huge yuan power contained in it, Jiang Xincheng had a feeling of being overwhelmed.

Because the coal is a seventh-level yuan stone, or a seventh-grade high-grade yuan stone, the yuan power in it is not only strong, but also quite pure, and can be used for the cultivation of the Great Yuan of the Rain Realm.

In the previous life, in order to compete for a coal mine, the major forces could dispatch thousands of powerhouses above the Condensing Cloud Realm.

But now coal is everywhere, no one cares at all, most people use it for fire.

In addition to being a seventh-grade high-grade Yuan Stone, coal also contains some strange substances, which are important fuels for refining various elixirs.

That's why Jiang Xincheng bought a bunch of coal to refine the Thick Earth Pill, and the Thick Earth Pill refined from coal is not only extremely effective, but also has the potential to raise the grade of the pill by one level.

Anyway, now that there is a lot of coal on the earth, no one will rob him, and Jiang Xincheng will be able to have a luxury.

Watching painfully as pieces of seventh-grade coal yuan stones turned into flames, Jiang Xincheng began to refine the Thick Earth Pill.

The divine consciousness fluctuated, penetrating into the alchemy furnace, controlling the temperature and flames.

Half a catty of osmanthus soil nourished by the Yuan Force in Jiang Xincheng's body was put into the alchemy furnace by him, and with the burning of the flames, the Yuan Force was dense, and the osmanthus soil gradually turned into yellow juice.

Dozens of minutes later, half a catty of osmanthus soil turned into dozens of drops of juice that exuded a misty glow, and Jiang Xincheng put in half a catty of osmanthus soil again and continued to refine and purify.

In the sea of divine consciousness, wisps of divine consciousness spread out, enveloping the alchemy furnace and flames, and at the same time, the yuan power was released, stirring with the osmanthus soil in the alchemy furnace.

For another few tens of minutes, there were dozens of more drops of yellow juice in the alchemy furnace, and several times, there was already as much juice in the alchemy furnace as there was a bowl.

Jiang Xincheng then began to add spiritual herbs such as shepherd's cabbage and mulberry leaves in turn, carefully controlling these spiritual grasses to merge into the yellow juice.

With the addition of the same spirit grass, the yellow juice in the alchemy furnace began to rotate, and at the same time, the water inside steamed out little by little, turning into a rich fragrance of Yuan Li.

Just taking a deep breath, Jiang Xincheng felt that the Yuan Force in his body had grown a little, and a smile crossed his face, it seemed that the quality of this furnace of Thick Earth Pill was good.

Time passed little by little, and all the spirit grass had entered the alchemy furnace, and the yellow juice in the alchemy furnace had turned into a multicolored color at this moment, and it was spinning faster and faster.

Layers of sweat appeared on Jiang Xincheng's face, his divine sense and Yuan Force were still too little, and it was quite difficult to refine the Thick Earth Pill, if it wasn't supported by the experience of his previous life, he was afraid that this furnace of pills had already exploded.

I don't know how long it took, Jiang Xincheng's face changed slightly, and he pointed to the alchemy furnace with both hands: "The sky is spinning, and the elixir is out." ”

When the words landed, the lid of the alchemy furnace "banged" up, and a ball of medicinal mud spun and jumped up from the alchemy furnace, spinning endlessly.

As the medicine clay rotated, a finger-sized thick earth pill with a yellow body appeared in front of Jiang Xincheng.

A smile crossed his face, and with a finger of his hand, this Thick Earth Pill fell next to the alchemy furnace, and Jiang Xincheng shouted again: "The sky is spinning, and the spirit pill is out." ”

Several times, the nine Thick Earth Pills fell in front of Jiang Xincheng one by one.

Jiang Xincheng sweated profusely and picked up a thick earth pill, feeling the majestic yuan power in the elixir, and a touch of surprise crossed his face.

First-grade medium-grade, these nine Houtu Pills are actually first-grade medium-grade elixirs.

The Houtu Pill is only a first-grade low-grade elixir, which can be provided to the cultivation of the Flesh Realm Yuanshi, but now it has actually become a first-grade mid-grade elixir, which means that the effect of these elixirs has more than doubled.

The rich experience of the previous life, the rich medicinal power of the osmanthus soil, and most importantly, the powerful effect of the coal fire, allowed Jiang Xin to sincerely refine a panacea beyond the grade.

Looking at the thick earth pills in his hand, Jiang Xincheng's face was full of smiles, he pinched one and put it in his mouth, and began to cultivate.

With the entrance of the Thick Earth Pill, the majestic Yuan Force appeared in Jiang Xincheng's body, and he hurriedly ran the Devouring Universe, devouring the huge medicinal power of the Thick Earth Pill in large gulps, improving his strength at a lightning speed.

With the Houtu Pill in hand, Jiang Xincheng's cultivation speed will skyrocket several times, and he must win tomorrow's battle, even if Liu Yifeng is the pride of heaven at the peak of the early stage of muscle training.
