As for the cultivation of the clone, the promotion is even more terrifying.

Originally, it was the body of the innate and acquired magic weapon, and then it was blessed with a hundred years of spiritual energy washing and reshaping the body, among the hundreds of millions of monks in the world, Xu You's qualifications as a doppelganger can definitely be ranked in the top ten, and it can even be compared to the elite Tianjiao of those upper sects.

Now, the cultivation of the clone has broken through the ninth layer of refining weapons and reached the peak of the ninth layer of qi refining, and it is only one step away from the tenth layer of qi refining. This is still Xu You's clone spending half of his time to improve the Imperial Artifact Technique, otherwise, Xu You's clone is likely to have broken through to the tenth layer of Qi refining.

In the art of imperial objects, Xu You's improvement is the greatest.

There are many classics in Xingyun Gate, and there are actually a lot of them about the art of imperial objects, and Xu You can be regarded as the head of a hundred schools and created his own way of imperial objects.

It is to bless a powerful force, to a small object, and then hit it at a very fast speed, which requires extremely strong, even inhuman control power, fortunately, Xu You has it at this point, stronger than the vast majority of monks, after all, as mentioned before, his talent and potential are comparable to or even surpass those top Tianjiao disciples of the upper sect.

Xu You has experimented, he can already bless the power of 100,000 jin on a piece of iron stone the size of a dragon's eye, and directly hit it, which can instantly produce a speed comparable to ten times that of a flying sword, it can be said that even a monk in the early stage of foundation building can cast any defensive spells and magic weapons, and he can't resist it.

However, this move also needs to bear a great burden on Xu You himself, so it is not a magic spell that can be used frequently, but fortunately, Xu You has studied a set of sword formations.

The basic technique used in other people's sword formations is the Imperial Sword Technique, while the one used by Xu You is the Imperial Object Technique. There is a difference between the two, in addition, Xu You's sword formation uses a very powerful set in the Nebula Gate, called the Tianluo Nine Star Sword Array, to refine the nine-mouth flying sword, but also to refine the mother sword box, and engrave a special formation in the sword box, which corresponds to the formation on the nine-mouth flying sword to form a special Tianluo Nine Sword Formation.

And whether it is a flying sword or a sword box, they are all magic weapons, especially sword boxes, which ordinary monks can't get at all, even some so-called refining masters, they can't refine them.

But who is Xu You?

What he is best at is refining, although his doppelganger is mainly for cultivating exercises, but if he wants to refine a weapon, it is the same as the ontology, after all, the doppelganger inherits the refining technique and level of the ontology, although it may be a little worse, but with Xu You's already Xuanjin-level refining realm, it is not too easy to let the doppelganger refine such a sword box and flying sword.

In this way, Xu You's clone can be regarded as having the usual offensive and killing weapons and spells, and another reason why Xu You values the Tianluo Nine-Star Sword Formation is that this set of sword formations is both offensive and defensive.

Xu You's favorite thing is to have both offense and defense, so that a set of spells and magic weapons can have multiple uses, which is called practicality.

As for the Boundary Artifact and the Boundary Key, Xu You also had a big breakthrough.

He had already refined some of the seventy-two accessory magic weapons used to assemble the Boundary Magic Weapon, but there were only twenty of them, although it was still far from being enough to combine them into a complete Boundary Magic Weapon, but after all, it was an extremely important step.

As for the realm key, Xu You also read in an ancient book that the refining requires the Shaping Boundary Stone, which is the key, and in addition, it also needs something from the other world, as long as it is contaminated with the breath of that world, it can be.

Fortunately, the Boundary Shaping Stone is available in the Nebula Gate, although it is not much, although it is not easy to get it, but it is still there, which makes Xu You's spirit lifted.

His clone was born in the Corpse Realm at the beginning, so Xu You's clone was contaminated with a trace of the Corpse Realm Qi, which was a ready-made thing, and the rest was to get the Shaping Boundary Stone and then refine the Realm Key.

However, on this day, Xu You was fiddling with the parts of the Boundary Magic Weapon he had refined in the Cave Mansion, when suddenly, he heard some movement, and then, the stone gate of the Cave Mansion of the outer gate actually rumbled open.

Xu You was taken aback.

You must know that only he has a jade slip to enter this cave, and others can't enter, of course, there is actually one person who can enter and exit at will, and that is Master Boxi.

Thinking of this, Xu You's eyes widened, and he secretly said Could it be that his cheap master is back?

At that moment, Xu You got up and walked out, and as soon as he walked out, he saw a monk standing at the door. This person has a goatee, a Taoist robe, a sword on his back, a gourd, his hair is tied up with a crown of cloth, and his feet are in Qingyun Square Shoes, isn't it Master Boxi.

"Master, are you back?"

Xu You was dumbfounded, and even forgot to salute, this master is really too unreliable, he just worshipped the master, and he didn't say goodbye the next day, and he didn't know where he went, if it weren't for Xu You's talent, and he was also diligent and hardworking, I am afraid that he has been wasting time for nearly a year.

Thinking about it carefully, Master Bo Xi has actually walked for more than ten months, nearly a year, which is really enough.

Bo Xi was smiling at the moment, glanced at Xu You up and down, nodded again and again, and deliberately said with a straight face: "Don't say hello when you see Master?"

"Master, the disciple is polite!" Xu You had no choice but to salute first.

"Okay, good!" Bo Xi was obviously in a good mood, he stepped forward and patted Xu You on the shoulder, and then seemed to have found something, and his pupils lit up instantly.

"Good fellow, you...... You are actually already at the ninth level of qi refining? Did you fly up from the flying crane in this cultivation?" Even Bo Xi couldn't help but exclaim, he had also seen many Tianjiao wizards in the sect, but none of them could do this kind of thing, in less than a year, he had cultivated from an ordinary person to the ninth level of qi refining.

You must know that when he came back, he had met the head of the sect, Pole Star Zhenren, who told him that the apprentice he had accepted was not simple, and he had already cultivated to the seventh or eighth level of qi refining.

As a result, when they met, it was even higher, and he was prepared before, otherwise he would be even more shocked.

Of course, Polestar didn't tell him that Xu You was a 'major repair' clone, because Polestar had agreed with Xu You that he wouldn't tell anyone but the two of them what he had speculated.

Therefore, Bo Xi only thought that he was lucky and picked up a cultivation wizard.

"Good apprentice, good apprentice, you really gave the teacher a big surprise. Bo Xi is naturally happy, but even more proud, his senior brothers often laugh at him, at first said that he has such a high status, but when the time came to accept apprentices, he didn't even accept an apprentice, and when he accepted an apprentice, he said that an apprentice is enough, and the apprentice he accepted is not good, he has heard a lot of similar words.

But now, Bo Xi wants to see who dares to laugh at him again.

My apprentice can't do it?

My apprentice confiscated it?

Bullshit, nonsense, you have a lot of apprentices, hundreds or thousands, among so many people, who can cultivate to the ninth level of qi refining in ten months?

Not a single one out of 100 percent.

This cultivation speed is even more powerful than those elite Tianjiao of the Shangzong.

The more Bo Xi thought about it, the more excited he felt, this time, he could raise his eyebrows.
