After Aotian quietly left the crowd with Mu Ling'er, they went back to Mu Ling'er's house together.

Mu Ling'er's home lives on the edge of the town, it is an ordinary small courtyard, and there are many flowers and plants growing in the courtyard, which seem to be Mu Ling'er's masterpieces.

"Father, mother, Ling'er, I'm back!" As soon as he walked into the courtyard, Mu Ling'er couldn't wait to shout.

Immediately, I saw a young woman dressed simply, walking out briskly with a happy face. But when she saw Aotian who was following behind Mu Ling'er, a trace of hostility flashed in her eyes.

"Ling'er, who is that person?" Seeing her daughter running in front of her, the young woman glanced at Aotian and asked in a low voice.

She already regarded Aotian as a member of the Black Dragon Gang in her heart.

"Mother, let me introduce you to you, this is Aotian, he is now the big hero of our North Seven Towns!" Mu Ling'er introduced to her mother with great pride.

"Hello aunt!" Aotian came to the young woman and greeted politely.

"Hello, hurry, hurry up, please!" Although the young woman didn't know the meaning of Lu Dao's daughter's words, she saw Mu Ling'er's reaction and knew that Lu Dao had just guessed wrong, so she felt that she seemed to be a little rude, and she also faintly felt that Aotian was not an ordinary person, so she didn't dare to slack off, and hurriedly invited Aotian into the house.

Aotian followed Mu Ling'er and the young woman into the simple house, the house was simply furnished, and there was no decent furniture, it could be seen that Mu Ling'er's family was living a very hard life.

Walking into the living room, Mu Ling'er immediately rushed to the man who was already sitting on the edge of the bed and waiting, and then hugged the man and began to be coquettish.

And the man was quite fond of stroking Mu Ling'er's hair, with a loving smile on his face.

Aotian guessed that the man must be Mu Ling'er's father, so he took the initiative to greet him.

And Mu Ling'er immediately introduced Aotian to his father, and then told his father and mother about Aotian's rescue in the Northern Wilderness Ancient Forest and the fact that he had just gotten rid of the Black Dragon Gang.

After learning the news that Aotian saved Mu Ling'er and eradicated the Black Dragon Gang alone, Mu Ling'er's father and mother were grateful and wanted to kowtow to Aotian to thank him, but he was stopped by Aotian.

Subsequently, Mu Ling'er's mother went out to Zhang Luo for dinner, while Mu Ling'er and his father chatted with Aotian.

In this way, Aotian stayed at Mu Ling'er's house for one night.

Early the next morning, Aotian decided to leave Beiqi Town and return to Aojia City.

Before parting, Aotian left some of the gold coins he had obtained from the Ou family's team to Mu Ling'er, and told Mu Ling'er that he would come to visit them again after a while.

......

After Aotian returned to Ao's house, Aotian first met Ao Changfeng, and then went to visit Ao Wuyuan, and while reporting to them that he was safe, he also reported his experience in the Northern Wilderness Gusen.

Of course, the situation reported by Aotian was basically made up, and the things about Xuan Qi, as well as the fact that his blood qi level had reached the top martial artist, and that he had suddenly gained a new strength, were all not mentioned.

After all, it was difficult for him to explain these things clearly for a while, and he didn't want Lang to bother to explain, so he simply buried them in his stomach, and he really couldn't hide them in the future.

Moreover, before Ao Tian came to see Ao Changfeng and Ao Wuyuan, he first inquired about the situation of the hunting team, and the hunting team led by Ao Jiexiong had not yet returned, so both Ao Wuyuan and Ao Changfeng should not know about Lu Dao's later departure from the hunting team.

Ao Changfeng and Ao Wuyuan naturally didn't doubt Aotian's words, and the two of them didn't ask Aotian why he came back alone first, but after giving Aotian some advice and care, he let him leave.

After seeing Ao Changfeng and Ao Wuyuan, Ao Tian left the mansion and came to the largest auction house in Ao Jia City, and auctioned the two medicinal herbs he had obtained from the deputy gang leader of the Black Dragon Gang before.

Two days later, the two medicinal herbs of Aotian were sold, and Aotian received 250,000 gold coins at once.

But Aotian did not leave these gold coins, but divided the gold coins into several points, and then sent several messengers from the Ao family to help send them to Beiqi Town and hand them over to Mu Ling'er.

Fantasizing about the excitement of Mu Ling'er's family when they saw the piles of gold coins, Aotian felt an indescribable sense of joy in his heart.

After this incident, Aotian also completely calmed down and began to cultivate in the past, but he was still not used to cultivating in the martial arts field, so he still came to the woods behind the family mansion every day and practiced alone.

The days have returned to dullness again, and Aotian is cultivating every day in addition to cultivation.

Gradually, he began to miss the exciting journey in the Northern Wilderness Gusen, and began to miss the bloody battles again and again.

"When my blood qi level reaches the martial artist level, I will go to the Northern Wilderness Gusen again to find medicinal materials for my father!" Aotian made up his mind in his heart, and when he had a goal, he would have motivation.

Therefore, I didn't care about the fatigue of practicing swordsmanship just now, and immediately began to do some extreme exercises on my body.

But not long after he exercised, Aotian suddenly noticed that there seemed to be someone in the woods on the side, so he immediately looked at it.

Sure enough, a masked man in black walked out from behind a large tree again, a smile flashing in his bright eyes.

Seeing this masked man reappear, Aotian was overjoyed and couldn't help but smile.

He knew that the masked man had come to fulfill his promise.

"Senior, I've already refined a kind of Xuan Qi!" Aotian said with excitement on his face, and he couldn't wait.

"Well, that's good, it didn't disappoint me!" the masked woman nodded and said softly, her eyes full of appreciation.

Hearing the woman's praise, Aotian smiled happily.

After a slight pause in the masked woman's voice, she changed her voice and asked, "Aotian, do you know the art of refining weapons and sword forgers?"

Hearing this, Aotian's heart moved, is the surprise that the secret woman wants to give herself has something to do with this?

"I've heard a little bit, but I don't know much about it!" replied Aotian truthfully.

"Well, then I'll tell you about it!" the masked woman nodded, and then began to gush about the art of alchemy and the swordsmith.

The art of alchemy is a superb skill, and it is also a skill with a high threshold. The original alchemy technique was mainly divided into three branches: weapons, armor, and artifacts.

Among them, weapons can also be subdivided into many small categories: such as knives, guns, swords, halberds, and so on.

However, on the Xuanwu Continent, the sword is regarded as the emperor of weapons, and many powerful martial arts are also in the same vein of swordsmanship, so the sword has become the mainstream weapon on the continent.

Therefore, in the art of refining, the sword-forging vein has been well developed, and now all refiners are majoring in the art of sword-casting, assisting in the practice of casting and refining other weapons and armor.

Therefore, today's alchemists are basically called swordsmiths.

The sword refined by the swordsmith is generally called a sword, and the sword is divided into yellow, xuan, earth, and heaven from low to high, and each level is divided into four qualities: low, middle, upper, and superb.

But even if it is a yellow-level low-grade sword, it can still sharpen iron like clay, extremely sharp, and if the quality is better, it can easily break through the martial artist's blood and qi cover.

And the Xuan-level sword, in addition to being tougher and sharper than the yellow-level sword, is also a strong sword with a strong connotation in the sword, which can be driven by blood and qi to shoot out a fierce sword qi, which is extremely powerful, even if the blood and qi defense released by the martial spirit strong can be easily broken, if the quality reaches the best, even the blood and qi defense released by the strong martial king can also be broken.

But the energy of the sword gang will be depleted, and once the sword gang is exhausted, it needs to be nourished and restored with blood qi and the demon core of the demonic beast.

As for the earth-level and heaven-level swords, they are powerful weapons that are fused with Xuan Qi refining, the power is extremely terrifying, and it also contains spirituality.

The legendary heaven-level sword can even independently exert supernatural powers and release powerful energy to protect its owner, and can also transform into different energy forms such as human form and beast form.

However, the power and supernatural power released by this kind of Xuan Qi energy that was refined into a sword were actually not as powerful as those displayed after being refined by the human body.

However, this at least makes up for the regret that many people are unable to drive the Xuan Qi energy.

Therefore, in this world where strength is respected, the sword that can enhance its own strength has become a treasure that countless strong people are crazy to pursue.

As a result, swordsmiths have become the most revered group of people on the mainland.

However, due to the very harsh conditions for becoming a swordsmith, the threshold is high, and the good sword-forging techniques are also in the hands of ancient sects and powerful forces, so the number of excellent swordsmiths can be said to be rare.

You must know that the swordsmith on the Xuanwu Continent is not the kind of ordinary blacksmith, holding a piece of fine iron, knocking and beating, the swordsmith here is using a special sword-casting technique to smelt different ores, energy crystals, magic cores, and the bones of some demonic beasts and many other materials, and then control many materials with spiritual power, and then control the change of flame temperature with spiritual power, as well as the fusion of various materials, Qualitative change, or even the final deformation and other changes, this process is also known as the spiritual power forging method, which does not require the forging method of hitting with a hammer, and uses the amount of spiritual power to control the qualitative change and deformation of the material, and then directly shaped, and the sword is already a finished product after it is baked.

Therefore, in order to become a swordsmith, you must first have blood qi, and your cultivation must at least reach that of a martial artist, so that the temperature of blood qi can smelt materials.

Secondly, it is necessary to have excellent mental perception and mental control, which is also the main factor that keeps most people out.

After listening to the masked woman's story, Aotian felt a burst of excitement in his heart, and he was already sure that the surprise that the masked woman wanted to give him was probably the art of refining.

And the masked woman's next words also completely confirmed Aotian's guess.

"You should also know why I want to wait for you to reach the level of a martial artist, or after refining a kind of Xuan Qi, and then surprise you, right?" the woman asked herself, "Although you have not reached the level of a martial artist now, but you have Xuan Qi in your body, you can use the energy of Xuan Qi to turn into flames, and that kind of temperature is definitely far more than the temperature of the blood gas of a martial artist, and the smelting of materials will be more sufficient, so the person who has Xuan Qi in his body is the most suitable person to become a refiner."

But in addition, there is a very demanding requirement, and it is also a condition that keeps most people out of the door, that is, excellent mental perception and control, based on my observation of you, your mental perception and control should be fine, so you should be able to become an excellent swordsmith!"
