Back in the cave, it was already late at night, Chu Xun walked into the bedroom, activated the spirit gathering array on the leyline qi, and sat on the futon.

With a pat on the waist storage bag, two rays of light flew out. There were two more golden jade bottles in his hands, one with a yellow wooden cork to plug the mouth of the bottle, and the other with a green wooden cork to plug the mouth of the bottle.

Poo!

The two corks were pulled up, and suddenly two streams of light, one yellow and one green, rushed out of the bottle, and then the whole bedroom was filled with a mixture of fragrance and sweetness.

The jade bottle that rushed out of Huang Xiaguang contained the Four Rank Ascension Pill.

The jade bottle that rushed out of Qingxia Light contained the Four-Rank Ascension Pill.

These two kinds of pills, any one of them is worth nearly a thousand first-grade spirit stones, if Chu Xun usually uses the four-grade pill to cultivate,

Now it is different, because he is fighting in the exchange and competition between the two sects, turning the tide, and winning a four-grade spirit stone vein for the Cloud Sword Sect, as long as he has not broken through the foundation, the sect will always provide him with all cultivation resources for free, and these two four-grade pills are one of the cultivation resources.

The two four-pinned pills melted in the mouth, like two cool mountain spring honey water, running down the throat and straight down the abdomen.

After taking the pill, Chu Xun slapped the storage bag again, and suddenly there were two more fourth-grade spirit stones in his hands, holding one in his left and right hands, his eyes were slightly closed, his mind was calm, and the seven-grade cultivation method Nahai was running violently.

The seven-grade cultivation method Nahai Duel, which is more domineering than the five-grade cultivation method gathering the sea, is just a quasi-turn, and there is a loud sound in his body, as if the water of the river is flowing.

The four-grade elixir, plus the four-grade spirit stone, the current cultivation speed is about two and a half times faster than when the three-grade pill and the fifth-grade cultivation method were used before.

According to the current cultivation speed every day, it would not take more than three months for Chu Xun to break through the eighth level of Qi cultivation and reach the ninth level of Qi training.

At this time, in the dantian spirit pool, a red mang, as if a red goldfish was swimming in the spirit pool.

If you look closely, you will find that the red mang is not a red goldfish at all, but a crystal clear, like a blood-colored long knife polished with rubies.

Ever since in the main peak hall, the Mad Demon Knife Decisive Jade Jian suddenly burst into red light and turned into a red point of light and submerged into the body, Chu Xun Dantian Lingchi has undergone a huge change, and there is such a blood-colored long knife.

At first, Chu Xunkai was greatly surprised, and when he touched the blood-colored long knife in the spirit pool with his spiritual power, an extra stream of information suddenly appeared in his mind.

Only then did I know that the ancient combat technique jade slip that recorded the mad demon sword duel not only had the mad demon scripture and the mad sword duel, but also sealed a weapon that had not yet recognized the master, the 'Blood Shadow Demon Knife!'

Moreover, the moment the Blood Shadow Demon Knife submerged into his body, the Blood Shadow Demon Knife had already automatically recognized its owner and became his natal weapon.

A monk's natal weapon is often much more powerful than using any weapon of the same level, which can be called a killer weapon!

Only when a monk becomes a monk in the foundation building period can he create a natal weapon, and only then can he recognize the master with the blood of the magic weapon, collect it into his body, and conceive it in the dantian spiritual pool, so that the natal weapon can break through the grade and evolve by itself.

As for the fact that he didn't reach the foundation building period, but made the Blood Shadow Demon Knife sealed in the jade slip recognize the owner and become his natal magic weapon, Chu Xun didn't think about it so much, after all, everything happened, what was the use of thinking about it?

It's a pity that in that message, in addition to telling Chu Xun that the Blood Shadow Demon Knife is a natal magic weapon that has not yet recognized the master, and how to make the Blood Shadow Demon Knife grow rapidly and improve its quality. It didn't say what material the Blood Shadow Demon Knife was made of, what level of natal artifact it was?

This point made Chu Xun feel uncertain, and he didn't know if the grade of the Blood Shadow Demon Knife was good, or not?

You must know that the materials used to make the natal artifact and the level of the person who created it will be good or bad, and the speed of the advanced grade will be far from the sky.

However, monks can only conceive one natal weapon in their lifetime, and many people would rather collect materials and ask someone to build a natal weapon many times than use a bad natal weapon as their own.

In Chu Xun's opinion, the Blood Shadow Demon Knife was not like a good natal weapon, because after a good natal weapon was created, it could be a fifth-grade magic weapon at the highest.

A bad natal weapon, after it is created, is a first-class magic weapon, and no one will drip blood to recognize the owner of this kind of natal weapon. Only the natal weapon that is equivalent to the second grade or more will someone drip blood and recognize the Lord as a natal weapon.

And at this time, the aura on the Blood Shadow Demon Knife, not to mention that it is equivalent to a second-grade magic weapon, has not even reached the first-grade magic weapon, and it is not much different from an ordinary mortal weapon.

The Ancient Combat Technique Mad Demon Knife Decisive Jade Jian sealed such a garbage natal weapon, although Chu Xun was a little disappointed in his heart, but he was a little unacceptable and depressed about the three methods that allowed the Blood Shadow Demon Knife to advance quickly.

The first is to let the Blood Shadow Demon Knife kill a large number of living beings, and drink the blood of all living beings to improve their rank.

The second is to let the Blood Shadow Demon Knife absorb the spirituality of various high-grade irons to improve the level of the Blood Shadow Blade.

The third way is to use ten magic weapons of the same grade at the cost of letting the Blood Shadow Demon Knife absorb the spirituality in the magic weapons to improve the level.

The first way to drink the blood of all living beings to improve the grade, there are too many demons and evils, which makes Chu Xun feel a little disgusted in his heart.

The first is to use the natal weapon to absorb the spirituality in the high-grade iron to improve the level, which consumes too much money and ordinary people can't afford it.

And the third kind uses ten magic weapons of the same grade to improve the level of the Blood Shadow Demon Knife, which is good in the early stage, ten first-grade magic weapons are not much money, and only two or three hundred first-grade spirit stones can make the Blood Shadow Demon Knife improve to the level of a first-grade magic weapon.

And the money for ten second-grade magic weapons is not much, only three or five thousand first-grade spirit stones can be used to raise the Blood Shadow Demon Knife to the level of second-grade magic weapons. Chu Xun can take it out at will.

It is the money of ten third-grade magic weapons, and Chu Xun can also take them out without frowning, it is nothing more than forty or fifty thousand first-grade spirit stones, which can make the Blood Shadow Demon Knife be upgraded to a third-grade magic weapon.

Even if it was a four-grade magic weapon, Chu Xun gritted his teeth, tightened his belt, and exchanged all his belongings and some of the item rewards and sect points obtained in the big competition for spirit stones, and he could also make up 1.8 million one-grade spirit stones and buy ten four-grade magic weapons.

But the next ten pieces, the fifth, sixth, seventh, eighth, and ninth grade magic weapons, what should I do with the magic weapons above the king grade?

If the natal magic weapon wants to advance to the king product or above, I am afraid that the entire Cloud Sword Sect will be sold, and it will not be possible to get the spirit stones that can buy ten king products?

What made Chu Xun happy was that those three were just ways to make the Blood Shadow Demon Knife advance quickly, not the only way to make the Blood Shadow Demon Knife.

Using the Dantian Spirit Pool to conceive and nourish the natal magic weapon Blood Shadow Demon Knife can also make it improve its grade, but this method is not as fast as those two methods.

Of course, most of the monks in the entire immortal cultivation world also use the spiritual power in their bodies to conceive natal weapons, and use high-grade iron ore to improve the grade of their natal weapons.

This method of killing all souls and using the blood of all spirits to improve the level of the natal weapon is only the method of the natal weapon of the Demon Dao monk.

And the method of using ten magic weapons of the same grade to improve the monk's natal magic weapon, I'm afraid that no one in the entire immortal cultivation world has ever heard of it?

Early in the morning, Chu Xun woke up from his cultivation, he got up and stretched his waist, stretched his muscles and bones, patted the storage bag, hula, and a bunch of weapons appeared on the ground.

This pile of weapons, no more, no less, exactly ten first-grade magic weapons, ten second-grade magic weapons, and ten third-grade magic weapons, all of which he bought during the day.

A red light flew out from Chu Xuntian's spirit cover, turning into a blood-colored long knife and slashing at a one-grade magic weapon.

Click-

In the next moment, countless tiny cracks appeared on the first-grade magic weapon, like spider webs, and at this time, some light could be seen flying out of those tiny cracks, being devoured and absorbed by the Blood Shadow Demon Knife.

There was a crunch.

The one-rank magic weapon, which was full of cracks, suddenly collapsed and turned into a pile of white powder. Under the sound of a broken magic weapon, the blood-colored light on the Blood Shadow Demon Knife became brighter and brighter.

In a moment, with a cheerful sound of the sword, the Blood Shadow Demon Knife advanced to the first grade.

Then there was a sound of magic weapons exploding, and the Blood Shadow Demon Knife advanced to the second grade.

In the end, when the last third-grade magic weapon on the ground collapsed and shattered, the Blood Shadow Demon Knife shook violently, and the knife roared, advancing to the third-grade.
