Four years later, Fang Buyi finally reached the ninth layer of the Qi Refining Period, which was the last layer of the late Qi Refining Period, under the feeding of sufficient spirit stones and pills.

Now, he has to consume two middle-grade spirit stones every day in order to continuously increase the capacity of the dantian qi sea to store more spiritual power.

Fortunately, Qu Changsheng, as the chief refiner of the Shang Kingdom, received a lot of resources from the Ministry of War, including low-level to high-level spirit stones, as well as various raw materials needed to refine magic weapons, and so on.

Only in this way could Qu Changsheng have enough spirit stones and pills to cultivate Fang Buyi into a container he needed.

As a price, Qu Changsheng signed a military order, except for some additional orders, he must hand over five second-level treasures or top-grade magic weapons to the Armaments Department every month, and one third-level treasure or top-grade magic weapon every three years.

In the Shenzhou Continent, magic weapons are divided into nine levels, and each level is divided into six grades: mortal, lower, medium, high, treasure, and superb.

This is an official standard jointly formulated by various countries in order to facilitate the trade of ritual weapons, which is very simple and straightforward. As for everyone's private classification, it is so varied that it is difficult to describe them all.

Each level of magic weapons requires corresponding strength.

For example, second-level ritual weapons can only be driven by monks above the foundation building period; Third-level magic weapons can only be driven by monks above the Jindan stage; Fourth-level magic weapons can only be driven by monks above the Yuan Infant Stage, and so on.

Therefore, don't look at the small number of magic weapons that Qu Changsheng handed in, the value is very high.

In the market, a second-level treasure magic weapon can at least be sold for a good price of five thousand spirit stones, although it is only a low-level spirit stone.

And the third-level treasure magic weapon can be sold for at least five thousand middle-grade spirit stones, which is equivalent to five hundred thousand low-grade spirit stones, and it has no price.

Generally speaking, only magic weapons above the third level can be mixed with the essence blood of monks and refined into magic weapons, so their value has been qualitatively improved.

As soon as he thought of Fang Buyi's extravagant cultivation method, Qu Changsheng felt extremely distressed. This kid has already eaten at least two third-level treasure artifacts.

This is a weapon that many Jindan period monks can't ask for, and it was wasted like this, if it was an ordinary disciple, he would have been expelled from the sect a long time ago, and even rectified the Fa on the spot.

But Fang Buyi was the most critical part of Qu Changsheng's plan to revitalize Tianyimen, so he didn't dare to do anything with him.

※※

One day, as soon as Fang Buyi finished his daily cultivation, Qu Zhi actually came to check the capacity of Fang Buyi's dantian.

He nodded and said with satisfaction, "Well, it was not in vain that so many spirit stones were wasted. The capacity of your dantian is already equivalent to that of a monk in the late stage of foundation building, so follow me to refine the weapon tomorrow. ”

The biggest feature of the Ethereal Root is that the capacity of spiritual power is extremely amazing, although it can't generate spiritual power by itself, and it can't practice any offensive spells, but as an assistant to a refiner, it is very good.

Now Fang Buyi is only in the late stage of qi refining, but the capacity of spiritual power has reached the level of the late stage of foundation building, which has to be said to greatly exceed Qu Zhijing's expectations.

He thought proudly: "If this kid is cultivated to the late stage of foundation building, wouldn't the capacity of spiritual power be equivalent to the late stage of Jindan?" If you train him to the late stage of Jindan, or even the late stage of Yuanying......"

It seems that the old man often said that with the ethereal root, Tianmen will be able to regain its former majesty, which is not a lie.

According to the old man, as long as Fang Buyi was cultivated to the Jindan stage, he would be able to refine a fifth-level magic weapon according to the secret of the old ancestor.

You must know that fifth-level magic weapons can only be driven by monks above the god transformation stage. As the first sect in the world, Tianyi Sect is really sensational and unbeatable. There are even rumors that the exercises of Tianyi Sect are given by the immortals of the upper realm, and they are not things from the human realm at all.

Next, Qu Zhi actually taught Fang Buyi a unique spell "Spirit Rhino Seal" that is unique to Tianyimen.

According to what Qu Zhijing heard from his father, the ethereal root cultivator, as a container, has the greatest role of delivering spiritual power to the refiner.

And the Spirit Rhino Seal is a spell created so that the container can transmit spiritual power to the refiner.

This spiritual rhino seal is very convenient, as long as both sides have a spiritual rhino seal, they can communicate with each other within a certain range, and the higher the realm, the wider the range of communication. And the closer the two sides are, the stronger the effect.

Therefore, the meaning of "Lingxi" is just that the spiritual power of the two sides can be connected within a certain range.

However, the Spirit Seal has a limitation, that is, it must have the participation of the Ethereal Root Monk in order to be effective.

If it is used by two ordinary monks at the same time, it will have no effect. Therefore, the "Spirit Rhinoceros Seal" is almost a spell specially prepared for the Ethereal Root Monk.

Fortunately, this "Spirit Rhino Seal" is extremely simple, and it only took half an hour for Fang Buyi to fully grasp it.

Early the next morning, Qu Zhi actually led two jailers to the iron gate and said to Fang Buyi, "I'll take you to the refining room today." ”

Fang Buyi pouted and thought, "Lao Tzu is finally going to work for these turtle grandsons for nothing." ”

Regarding the matter of the refining room, he had already heard Jiang Liu'er say it many times, so he was not so surprised. It's just that I heard that the refining process is extremely hard, and the boss in my heart is unwilling.

A jailer opened the door and came in, and put a black cloth bag on Fang Bu's head, and Fang Buyi couldn't see anything.

Qu Zhi and the jailer led the way, and Fang Buyi only felt that he had walked into a gloomy tunnel.

This tunnel was like a long snake, winding forward, and the four of them walked for half an hour before stopping.

Fang Buyi only heard the sound of a key unlocking, followed by the sound of a huge and heavy stone door being opened.

Then the locks were unlocked and the doors opened, and so on all the way to the nine stone gates.

Fang Buyi stepped through the stone door and felt like he had walked into a huge furnace. The temperature rose suddenly, and he almost fainted from the heat without the support of spiritual power.

Then the hood was removed, and he was immediately speechless by what he saw.

In front of me is a huge stone hall with a diameter of more than 100 zhang, in the shape of gossip. The roof of the temple is dozens of feet from the ground.

In each hexagram, a huge furnace was placed, more than a zhang high, black and heavy, and I don't know what metal it was made of.

In the center of the gossip, there is a behemoth more than ten zhang high, suspended in the air. Under the top is a square high platform, with stone steps leading directly to it on all sides.

At the edge of the high platform, an old man in a gray robe sat cross-legged, it was Qu Changsheng.

I saw his palms stretched out, and cyan flames gushed out from his palms, flowing towards a five-zhang tall cyan pillar of fire in front of him.

This pillar of fire went straight to the bottom of the giant ding, obviously refining some high-grade magic weapon.

Behind the old man, Jiang Liu'er sat cross-legged, leaning against a six-foot-long and wide spirit stone, her eyes were slightly closed, and countless points of light emerged from her body, converging into a stream of spiritual power in the air, which flowed into the Fengmen acupoint on Qu Changsheng's back.

When Fang Buyi saw it, he already understood that Jiang Liu'er was sending spiritual power to Qu Changsheng, and the two of them thought that they had already formed a spiritual seal.
