In this way, Liu Xianyu took the long sword that the man gave him back and began to practice according to what the man said, injecting elements into the weapon is a familiar action for her, but it is a little difficult to operate the movement of the elements on the surface of the weapon without releasing them, because the more elements there are, the more difficult it is to control, not to mention compressing while increasing the amount of elements.

He only injected it for a few seconds before the expanding elemental burst out from the top of the sword, and the scabbard was pushed out by the wind elemental and landed inside the ore pile.

[This...... It's harder than you think. 】

Liu Xianyu climbed into the ore pile and picked up the scabbard, and began to try again.

Again and again, the principle that seems to be explained in a few words is extremely difficult to practice, at first it was three seconds, then five seconds, this time is fine, when it fails, it is just to pick up the scabbard that flew out, after about an hour of practice, Liu Xianyu can gradually extend the time to ten seconds.

Just when he was happy about his progress, the element injection in his hand suddenly increased a little bit, and it was because of this little bit that the wind element that had lost its balance suddenly exploded, several wind blades flew out from the middle of the scabbard, the scabbard was bounced away, and Liu Xianyu's arm was also cut by the sharp wind blade, and the blood instantly soaked his clothes.

【Healing of Light!】 】

The silver-haired Lokas appeared behind him at some point and released a healing spell on Liu Xianyu, and soon the wound on his arm healed.

Thank you. 】

[It's nothing, but I remember that when my husband first learned this trick, he always made himself bruised, I think even if His Highness's talent is very high, he may be injured at the beginning, so I came to take a look. 】

Lokas smiled at Liu Xianyu euphemistically, which was different from Jade's shy smile that laughed unbridledly, and the feeling of smiling without showing teeth.

[Please continue to practice, I will always watch you here, although I haven't gone out to fight since I got married, but I am still very confident after using healing magic for decades.] 】

[Decades? 】

Liu Xianyu muttered in surprise.

[That's right, don't look at my appearance, I'm actually an old woman in her two hundreds. 】

[No, you still look very young, and it's not an exaggeration to say you're twenty. 】

[That's right, even if Lockas goes out now, he can still attract a group of hairy boys. The last time I went out, wasn't there anyone kneeling in front of me and shouting "father-in-law". 】

The man's voice came from the entrance to the courtyard.

[Really, don't make fun of me pulling! 】

Lokas seemed a little embarrassed in the face of her husband's words, and gently hammered his chest, maybe because Liu Xianyu was listening to it.

Looking at the interaction between the two people, Liu Xianyu suddenly felt that after collecting all the points and having no worries about life, he must find a plump spirit girl to marry, just like his own enlightenment teacher!

[The trick of sealing the blade is to seal, don't rush to infuse too many elements on the blade, step by step, the speed at which you infuse the elements is too fast, when I first mastered it, I often spent a whole day to infuse the elements little by little, and it took more than ten years to achieve this speed. 】

[Is that so? It's me who is in too much of a hurry. 】

According to the man's statement, Liu Xianyu found that he was indeed a little impatient, so he ignored the couple who kissed me behind him, and he began to slowly inject elements into the weapon, because the speed was reduced, and the balance was maintained quite well this time, and in about a minute, Liu Xianyu could vaguely feel that the long sword in the scabbard began to tremble slightly.

[The amount of injection is almost the same, and a slight shake in the weapon means that you have succeeded, so pull it out and take a look.] 】

Liu Xianyu listened to the man's words, slowly stopped the injection of elements, and slowly pulled out the long sword in the scabbard. A layer of translucent aura visible to the naked eye continued to flow on the long sword, Liu Xianyu gently inserted the tip of the long sword down to the ground, effortlessly like cutting butter, the long sword was inserted into the ground, but when the sword body was halfway deep, the resistance appeared, and the power that surrounded the long sword disappeared.

[Disappeared? 】

[That's right, the elements you injected have been depleted.] 】

[I obviously injected a lot of elements and disappeared so quickly? 】

[No way, sealing the blade is such a costly skill, but because it can be charged at any time, when you are familiar with it, try to charge it when you are outside the battle.] By the way, I've been recharged for a year, and I'm very handsome when I use it, but the weapon in my hand is immediately damaged, so if you cherish the weapon, it's better not to recharge it for too long. 】

Liu Xianyu pulled out the long sword from the ground and inserted it back into the scabbard to start a new round of training, about two hours later, he has gradually mastered the basic points, although he will still be injured from time to time, but basically ten times will only have one failure.

[It's almost time, we're going back to rest, how about you take a break? 】

[No, I'm still practicing, after all, I'm just getting a little proficient.] 】

Liu Xianyu looked at the crescent moon hanging in the starry sky and said to the man.

[If you're injured, there's no one to treat you, so I won't let my wife stay with a strange man all night!] 】

[No...... I have my own cure, and Lady Locas don't have to worry about me. 】

[That...... Your Highness, be careful yourself. 】

Lokas still seems to care about Liu Xianyu's safety, no matter what, he is the prince handed over to her by her eldest brother.

The two of them left the courtyard full of ore and iron material hand in hand, while Liu Xianyu continued to practice the skill of sealing the blade alone.

[System, I want to exchange something.] 】

Liu Xianyu suddenly remembered the item he had seen a long time ago.

Endless Bottle: A bottle of strange material, despite its fragile appearance, but as hard as steel, and the bottle seems to occasionally appear a strange orange cloudy liquid, which has a weak healing effect and costs 1 point.

(Note: Let's drink fruit oranges together!) ）

This inconspicuous prop has been useless because of the existence of jadeite, and Liu Xianyu didn't think about exchanging it, but now is the time to need it, and after using up his last 1 point, Liu Xianyu put this bottle next to him and began to continue training.

Night gradually began to envelop the city, although some places were still brightly lit, but there was no sound in this remote street, and Liu Xianyu seemed to become more focused in the quiet environment.

[Wait for me, Ikatris, I will not fail this time!] 】
