And when Long Yuan's mind was unable to compress the True Qi, he summoned out a wisp of True Qi that ran along the specific meridians.

Suddenly, a roar erupted in Long Yuan's sea of qi.

"Success!" Long Yuan was overjoyed in his heart, after knowing how to cultivate, he knew that martial artists might fail in the process of breaking through and even have a chance to fall to the original realm, but this time he succeeded.

The four walls of the sea of qi collapsed again, and some of them expanded.

In the Qi Yuan Realm and the Transformation Realm, the Qi Sea will expand at every small stage of breaking through the Qi Element Realm, but after entering the Qi Flame Realm, only the True Qi will completely turn into a liquid state, and after filling the Qi Sea, the Qi Sea will expand again, and if it does not reach the Creation Extreme Realm of each realm, the Qi Sea will not be filled with liquid clear water.

Therefore, in the future cultivation process, Long Yuan will only collapse when he breaks through the Great Realm, which also means that he may fail to break through.

After the capacity of the Qi Sea increased, Long Yuan was still running the Fire Crown and Burning the Sky, and the Xuanfu around him and the beetle Dao on his chest were like a bottomless pit, frantically devouring the clear qi of heaven and earth.

While absorbing the clear qi of heaven and earth, Long Yuan also found that the impurities produced by the collapse of his qi sea were also excluded from his body, and this speed was faster than the speed at which he used to use the true qi to expel impurities, I don't know how much.

"Haha, the Transformation Realm has reached its peak. When everything was calm and normal, Long Yuan looked up to the sky and laughed, his whole body as if it had been moistened by rain and dew, and his whole body exuded a ruddy luster.

Taking out the Sky Ruler, Long Yuan went to the house and began to dance, and he also switched back and forth between the Heaven Ruler and the Heaven Fighting Moment, constantly changing the style between moves.

"After cultivating martial arts, all martial arts seem to be used much more smoothly and harmoniously than before. Long Yuan waved heartily and put everything he had learned into practice.

"After cultivating martial arts, my combat power should have increased by about one percent. Maybe with his current state, it will be no problem to win Chimeng who is half a step of the Aura Realm, but now it is estimated that he is not his opponent, and the gap between the Aura Realm and the Transformation Realm is really too big. Long Yuan muttered to himself.

However, Long Yuan was not discouraged at all, he now had everything he should have, and he knew everything he should know, he believed that in the near future, he would definitely be able to fight for the mountains and seas for his master.

Thinking of this, Long Yuan was also glad that the Mountain and Sea Treasure Book was not born on time as his uncle said, otherwise he would not have had time to meditate and cultivate at all.

"Hey, it's strange, I've obviously broken through the realm, and my strength has improved a lot, but why hasn't the feeling of fighting for the sky changed?" Long Yuan weighed the weapon in his hand, and it didn't feel lighter, it was still quite laborious.

Then Long Yuan tore off the Xuanshi heavy armor and raised his hands to fight for the sky, only to find that the weight of the sky ruler had increased.

"Could it be that with the improvement of my realm, the Heaven Fighting Ruler will also get worse? But I didn't feel anything strange when I broke through to the Qi Yuan Realm before, could it be because I broke through the Great Realm?" Long Yuan thought for a long time and didn't have a clue, and he didn't care, just now he felt very good holding the Heaven Fighting Ruler with a bandage in his hand.

"At the peak of the Transformation Realm, it's time to think about my natal weapon. However, refining the natal weapon and familiarizing it with it is too time-consuming and labor-intensive, and now that I am a refiner, I should go to the teacher and ask. ”

At this stage, Long Yuan naturally understood how to refine the natal qi blade, which required to take a drop of heart blood from the heart vein in the shape of a weapon in the shape of true qi in the body, and then wrap this drop of heart blood and sink into the clear water at the bottom of the sea of qi, and then let the heart and mind establish a connection with the clear water mixed with the heart blood, and finally visualize the shape of the weapon with the heart and mind, and use the gaseous true qi to forge and compress the clear water to form the shape of the weapon.

This process was very draining, and in Long Yuan's opinion, the Natal Weapon Weapon constructed in the Transformation Realm seemed to have the effect of exercising the martial artist's mental power.

Over time, the clear water mixed with the blood of the heart will take root at the bottom of the sea of qi, plant the air blade tire, and wait until the transformation realm is extremely formed, and the air blade tire will be completely formed. At this time, the martial artist can use the air blade anytime and anywhere, even if the qi blade is temporarily out of his hands, it doesn't matter, as long as there is still true qi in the qi sea, he can re-transform the qi blade.

The Qi Blade Fetus will grow with the Martial Artist, which means that the higher the cultivation of the Martial Artist, the stronger the Qi Blade will be.

An air blade tire can only be transformed into one type of air blade, for example, the air blade transformed by a sword-shaped air blade tire can only be a sword shape, if you want to use other shapes of air blades, you need to form another air blade tire.

This is also the biggest limitation of Mystery of Weapons.

In the battle of the warriors, after being familiar with the use of the air blade, the air blade is generally not used to fight, and is only used for self-rescue at the most critical moment. Because fighting with an air blade is quite consuming with true qi, it is better to use a weapon that is better in the world, wrap the true qi around it, increase its sharpness, or use a weapon refined by a refiner.

Of course, if you don't even have a better mortal soldier, then you can only use the air blade to fight.

Although Long Yuan can now construct a natal qi blade, he has not done so, since he can refine weapons now, Long Yuan feels that the matter of the qi blade can be put aside first.

After resting in the room for a day, Long Yuan went to the stone room to find Chihong on the second day.

Chi Hong had been impatient waiting for a long time, if it weren't for the fear of disturbing Long Yuan's cultivation, he would have gone to carry Long Yuan to the stone room.

Seeing Long Yuan coming to find him, Chihong's old face was as happy as a chrysanthemum. After testing Xia Longyuan's proficiency in the control of the Immortal Flame, Chihong was also quite satisfied.

"If refining your own natal qi blade in an ordinary way is very time-consuming, now that you have worshiped my disciples, you should learn to refine weapons first. The task of the Transformation Realm is to construct a natal weapon and familiarize it with it, so that it can save itself in the future if you are defenseless. However, the refiner can also send and receive the weapons he refines at will, and can achieve the same effect as the air blade. ”

"What, can the refined weapons be sent and received at will?" Long Yuan's eyes widened.

"Otherwise, how can the refiner take out the weapon after refining it in the inner ding? How can the inner ding break out of the body? Stupid! The refiner's sea eye is different from other martial artists, there is a 'golden paint' plated with metallic true qi in the beetle path, and the compatibility of its own true qi is high, so that it can absorb metal and rare materials into the body to refine weapons. Therefore, it is not difficult for refiners to send and receive refined weapons. Generally speaking, second-grade refiners are able to refine metals, as well as other materials. But before that, it is necessary to store a lot of metal in the sea of qi for later use, which can also improve the compatibility of metal and true qi. Metal can be sucked, let alone a weapon mixed with metallic true qi?"

"But Teacher, it always takes a process to take out a weapon from the sea eye, and it can't be sent and received like an air blade. ”

"I said, why are you so fond of digging into the horns, do you feel if there are two beetles leading to your hands near your sea eye. ”

Long Yuan looked inward according to his words, feeling in his body, he found that there was a golden pipe on both sides of his sea eye, which was a bit like a blood vessel.

"This ......"

Chihong's face showed a look of pride, and said: "You have to thank you for worshipping a good master, when I was refining the inner ding for you, I built two small beetle paths for you. This kind of beetle path can only be built by the refiner after reaching the fourth grade, otherwise he will have to ask a more advanced refiner to build it. With it, you'll be able to send and receive crafted weapons with ease. ”

"Thank you, teacher. Long Yuan smiled brightly, so that he wouldn't have to worry about refining the Natal Qi Blade.

"Teacher, is it possible that other martial artists can also take the refined weapons into their bodies and act as qi blades like me? ”

"No, you can't. ”

"Why is that?"

"Excuse me, can you give me a moment to stop?" Chi Hong picked up a small stick and used Long Yuan's head as a wooden fish, and knocked it vigorously a few times.

Long Yuan held his head, looked at Chihong with a look of resentment, and muttered, "Isn't the teacher just teaching and solving doubts?"

"Give your mother a head, solve the problem, your brain is used to raise fish? Without a strong compatibility as a backing, who would dare to absorb foreign objects into the sea of qi, and there is no metallic true qi to make the sea of qi adapt, do you want it to fry? Next, give me practice refining weapons, and ask again, I will knock you to death!" Chi Hong was so angry that he blew his beard.

Long Yuan pursed his lips, and he didn't say anything more.

"You separate the true qi from the flame in the sea of qi, pour the true qi into the refining furnace, and calcinate it at the bottom of the furnace with an inextinguishable flame to refine the true qi. How to use the refining furnace, figure it out for yourself. "Chi Hong Dao.

Long Yuan touched his nose and sat cross-legged, his mind entering the sky above the sea of qi.

There is a Ding furnace there, the whole body is like glass, and the glass seems to have some pale golden veins, the shape is similar to the round golden beast incense burner of incense, with three legs and two ears, and there is an inverted lid on it. The height of the furnace is half a zhang, and the diameter is less than five feet. There are three burners under the abdomen, which are sandwiched between the three legs.

The inside of the stove is different from the ordinary stove, the general stove is the stove mouth directly to the bottom of the pot, and the inside of the stove of this refining furnace has two upper and lower channels, which seem to be like sheep intestines, twisting and turning. One of the passages leads to the bottom of the stove, above the inside of the stove, and the other is directly connected to the bottom of the pot, below.

The bottom of the furnace is like an inner tank, and like a giant bird's egg. Through the inner tank, Long Yuan found that there seemed to be a dark grid on the inner bottom of the refining furnace, which was connected to the channel directly connected to the bottom of the pot in the stove. The other two burners are also of the same design.

Long Yuan's mind observed this gas refining furnace, and then invoked his mental power to try to familiarize himself with the operation.

Fortunately, the refining furnace is not too difficult to use, and some parts only need to be concentrated and urged by mental power, that is, they can be controlled through the mind.

As soon as his mind moved, the lid of the refining furnace flicked open, and then Long Yuan transferred the true qi in the sea of qi into the refining furnace. At this time, he realized that the Ding Furnace in the Qi Sea was like a bottomless pit, and it was not until he poured one-fifth of the total true qi in the Qi Sea into it that the Ding Furnace gradually showed signs of being filled.
