"Okay, no need to be polite, this can be regarded as your reward for taking care of the medicine garden for me. Su Yang Zhenren said calmly.

According to the rules of the immortal cultivation world, teaching the law is a teacher, and it is necessary to perform the great bow of three kneels and nine bows, which can be regarded as respecting the teacher.

However, Lin Yu is not a person who sticks to the rules, and although Su Yang Zhenren is willing to instruct himself, he has never intended to accept apprentices, and he is not easy to go beyond too much, but he is afraid that it will be self-defeating, but it will destroy the relationship between them.

"I still want to concentrate on alchemy, so I'll go back to the Danxin Hall first. As for the matter of the inner gate, you don't have to worry too much, the way of heaven is the public, since you have done nothing wrong, they will not embarrass you. This move is just a means for Zhang Xing to save face, and during this time, you just need to concentrate on cultivation. ”

After instructing the matter, Su Yang Zhenren's figure rose into the sky, and only then did he step on a void sword qi, cut through the sky, and disappeared into the depths of the sky, which can be called coming and going like the wind.

After he left, Lin Yu also sighed slightly, recalling the moment of life and death today, he still had some palpitations.

"Suyang Zhenren is right, I have to improve my means. Although the Fire Raven Array is fierce, it is okay to fight with people, but it is worse to kill people. ”

With this thought, he raised his head, returned to the grass hut, sat down directly, and entered the cultivation realm of meditation and concentration.

"I should first practice the 'Shaoyang True Fire Technique' to strengthen the foundation of mana, and only when the Dao is strong can I be able to use superb means. ”

Lin Yu didn't say a word, he sacrificed the five yin bags, took out the "Shaoyang True Fire Technique", put it flat on his chest, and studied it carefully.

"Shaoyang True Fire, cultivation, is to absorb the power of the Great Sun Sun True Fire, warm and nourish the natal true fire, and produce a qualitative transformation. This flame is cultivated, and there are Xuanyang True Fire, Supreme Yang True Fire, and Pure Yang True Fire upwards. Cultivating to the extreme, it is possible to turn into the true fire of the sun, which can incinerate all things and incarnate into the great sun. ”

After studying it for half an hour in one breath, he understood this exercise thoroughly, and immediately raised his head, came to the door, and took advantage of the noon, when the sun was just right, to sit down, run the exercise, and begin to absorb the power of the great sun.

The cultivation methods of Xuanmen Taoism are far less obscure than those of Buddhism, and they are usually easy to understand. The real difficulty is how to cultivate, take this "Shaoyang True Fire Technique" as an example, it is extremely simple to cultivate, you only need to continuously refine the power of the Great Sun, integrate into the natal true fire, and change the essence.

After the Shaoyang True Fire is completed, it will transform into the Xuanyang True Fire, and constantly improve its power until it is practiced into the True Sun True Fire.

This process may seem simple and ordinary, but in fact, it has many limitations.

The physique of an immortal cultivator is a big bruise, and when he cultivates to the Xuanyang True Fire, the power of the natal flame will reach a very strong level, and at this time, he must find a way to enhance his physique to suppress the power of the True Fire. Otherwise, you will burn your own body and all your penance will be in vain.

Therefore, most of the Daomen monks can only raise the natal true fire to a certain realm, and they can't continue. In this way, the hope of immortality is also cut off, so the fire path method is generally only used for fighting and killing, and few can directly point to the path of immortality.

"Fortunately, I have martial arts kung fu to stabilize my body, and for the time being, the power of the Yang True Fire can still be withheld!"

For Lin Yu, there was no problem in cultivating Shaoyang True Fire, although Hu Susu absorbed part of the power of the Wind and Thunder Overlord Body, but he did not damage the origin, and after a few days of hard training, he recovered his strong physique and was able to withstand the power of True Fire.

He ran the "Shaoyang True Fire Technique" and sacrificed the natal true fire, and the three hundred and sixty true fire seeds in the acupuncture hole appeared around his body, flashing with dazzling firelight, constantly swallowing the power of pure yang in the heavenly sun.

After a while, these true fire seeds had a fundamental change, and the original dark yellow flame gradually added a trace of red light, which was somewhat similar to the great sun in the sky, and its power was constantly rising.

The sun sets and the moon rises, the stars change, and for a cultivator like Lin Yu, time is like flowing water, always passing inadvertently.

In the blink of an eye, it was late at night.

After a whole day of hard work, he finally cultivated the Shaoyang True Fire preliminarily, and all the fire in his body was transformed into a reddish flame, which was more than twice as powerful as before.

When the sun set, he couldn't absorb the power of the Great Sun to cultivate, so he had to stop cultivating, stand up, and walk towards the grass hut.

Although it was already midnight, Lin Yu was not tired, and after some cultivation, his mana had improved, and he was in a state full of energy.

"Now that I have cultivated the Shaoyang True Fire and have the Vacuum Sword Codex, it's time to build a suitable long sword for myself. It's just that now there is not enough materials, and there is no earthly evil spirit, which can allow me to condense. I can only refine the five yin bags first......"

With nothing to do, Lin Yu had the idea of refining the magic weapon again, but instead of refining the long sword, he took out the cicada wing knife and the five yin bag and put them in front of him.

The Cicada Wing Knife is a high-grade talisman with good quality, but it is only suitable for monks in the Qi Condensation Realm, and Lin Yu has now practiced mana, and it is a little uncomfortable to use it again.

As for the Five Yin Bag, it was originally a magic weapon of the Yinshan Sect in the Wild Land, and it had the highest quality, which could spew blood, destroy the magic weapon of the cultivator, and also refine the flesh.

However, Lin Yu thought that this magic weapon was too evil, so he removed the blood stain, and it no longer had superior quality, and could only be regarded as a low-grade magic weapon, which contained a space of ten zhang square, which could collect dead things.

Now, he took out the two magic weapons, just to re-refine the five yin bags.

The Cicada Wing Knife is useless, but the Xuanyin True Evil left in the blade is one of the seventy-two innate Earth Evils, which is rare in the world.

Lin Yu's plan was to take out this evil qi and refine it into the Five Yin Bag, so that this magic weapon could not only collect items, but also spew out the Xuanyin True Demon to hurt the enemy.

"It's a pity that this wisp of Xuanyin True Evil is too weak, and it's okay to use it to refine talismans, but if it is used to refine magic weapons, it's too insufficient. Refining into the five yin bags, when fighting with others, you can also take them by surprise and attack them unprepared. ”

Lin Yu sighed, and with a touch of his fingertips, the Shaoyang True Fire was released, wrapping the Cicada Wing Knife.

In less than a stick of incense, this long knife, which was as thin as a cicada's wings, turned into a ball of molten iron, and the true evil of Xuanyin contained in it was also revealed.

"Go!"

Lin Yu let out a low snort, and then crossed this wisp of Xuanyin True Evil into the Five Yin Bag, and immediately used his mana, and practiced wildly, the whole process was completed in one go, without superfluous movements.

As for the molten iron turned into by the cicada wing knife, he didn't waste it, and integrated it into the five yin bags, decorating this silk bag with a cold light, and the whole body seemed to be covered with a layer of iron sheets.

"Alright, it's finally done!"

At this time, Lin Yu let out a long laugh and received Shaoyang's true fire, and his mood was indescribably happy.

After he re-refined this Five Yin Bag, it has been completely renewed, not only has it added a wisp of Xuanyin True Evil, which can be driven at will, but its defense has also increased a lot, and it will not be easily destroyed.

What's more, the space contained in it has also been increased to a radius of 20 zhang, which is twice as much as before!

In this way, this magic weapon has been directly upgraded to the intermediate quality!
