Li Hua pointed to the pocket of the man in black and said honestly: "It's with the iron box you just took away! The only thing my mother left me, I didn't expect it to have such a wonderful effect." Using this iron box can quickly upgrade the magic weapon medicine, if it weren't for it, I'm afraid my current cultivation would still be dangling back and forth at the beginning of the first grade, and I wouldn't be able to break through!"

Uncle Wang suddenly realized: "I almost forgot that your father mentioned this iron box to me in the letter. He also instructed me to help you upgrade this iron box when I met you. ”

"Upgrade?"

Uncle Wang explained: "This iron box can also be regarded as an auxiliary magic weapon, but it has strong particularities, so there is no way to classify it according to grade. But it can also be refined and upgraded. I'm quite accomplished in the field of chemistry, which is why your father gave me this task and asked me to upgrade the iron box as soon as I met you. ”

Li Hua also guessed at the beginning that the iron box could be refined and upgraded, otherwise it would be too slow to use it to upgrade the high-grade magic weapon elixir, but it was a pity that such a magic weapon with special effects would be too slow.

But Li Hua was still not sure if his conjecture was correct, so he asked, "What are the benefits of upgrading the iron box?"

Uncle Wang smiled: "Of course, there are many benefits. The most intuitive one, with each level it up, the time to upgrade the magic weapon medicine will be cut in half. ”

Li Hua couldn't wait to hear the next benefit, "And then?"

Uncle Wang smiled and said, "Then you can only find out by yourself." So far, I've only known of one benefit. By the way, I forgot to tell you, I can only help you raise it by one level this time, and it will take about three days. ”

"When will you be able to level up?

"That's right, it takes three days to upgrade the iron box to one level, but if you want to go up another level, it will take thirty days. Now this iron box is level zero, and it will multiply tenfold every time it takes to upgrade one more level. In the process of refining it, I must not leave an inch, and I can only refine it by using chemical spells wholeheartedly. After that, no matter whether I succeed or fail, I need to take medicine, otherwise my body will degenerate due to too much consumption. This shows how much time and effort is required. ”

Just by talking, Uncle Wang's eyes revealed a deep sense of exhaustion, and he continued: "Uncle Wang is not afraid of trouble, in order for Brother Lei's only son to be able to cultivate immortals smoothly, it is naturally okay for me to sacrifice some. However, after three days, there is indeed a very important task that I need to complete, and it is urgent for me to do so. When I come back, I will definitely help you continue refining, even if it takes hundreds of years, I will definitely do my best to help you reach the clouds!"

Listening to what Uncle Wang said was so touching and profound, Li Hua's heart was filled with a warm current all over his body, no one could make him so moved for a long time, and he found the warmth of his relatives in an instant. He said very gratefully: "Uncle Wang, in fact, you don't need to worry too much about my affairs, I will move forward step by step towards college students with my own efforts." ”

Uncle Wang listened to Li Hua's words, and was also very relieved, "Child, I will take away your iron box first, and in the evening of three days, I will still be here, and I will wait for you with the iron box that has been upgraded to the first level." See you or leave you. If I have any special circumstances, I will let you know in advance. You won't be upset if the iron box left for you by your mother is here for me, right?"

Li Hua said with a smile: "Look at what you said, I don't worry about anyone, I can't worry about you! Take a step back, with your cultivation and strength, you just want my life at this time, what can I do? It's not just that I can just sit back and wait for death. ”

Uncle Wang nodded reassuringly and said, "Okay, you must be careful by yourself, in the world of cultivating immortals, you must be careful in everything." Let a sleeping dog lie. Try to calm down and concentrate on improving your cultivation, so that you have no distractions and don't take shortcuts. Just remember that, and I'll see you in three days, I'll be one step ahead. ”

As soon as the words fell, Uncle Wang's black figure flashed, and the whole person disappeared into the thick night.

Looking at Uncle Wang's distant figure, Li Hua couldn't help but sigh secretly, if Uncle Wang hadn't wanted to test his strength just now and didn't use his skills, I'm afraid he wouldn't be able to catch up with Uncle Wang.

After staying in place for a few minutes, Li Hua realized that it was not suitable to stay here for a long time, and he couldn't deal with it when he encountered a strong enemy, so he immediately turned around and ran home.

The place where his home is located is originally a suburb, and most of them were moved away from the relocation last year, so it looks very desolate at night.

The cool breeze in the middle of the night blew by, and beads of sweat appeared on Li Hua's forehead. He didn't expect that in this half an hour, he would run so far.

The moon was dark and the wind was high, he had never been to this place, standing where he was, he looked around, there was only a grove of trees and a desolate farmland nearby.

Fortunately, he didn't go too deep into the grove just now, otherwise with his confused sense of direction, it is estimated that he would not be able to go out this night.

However, although he did not enter the grove, he also felt that it was difficult for him to get out of the barren field.

The night was getting thicker and thicker, and the cool breeze was blowing more and more infiltration.

Li Hua really regretted that he didn't let Uncle Wang take him out first. But after thinking about it, he can't even get out of this place, how can Uncle Wang still rest assured that he can rest assured?

But it's not his fault that the sense of direction is too poor, Li Hua kept walking to the right, walked for more than an hour, and still didn't go out.

In order to avoid a similar situation from happening again, Li Hua swore to the sky that after going out, no matter how many spirit stones it would cost, he would definitely buy a compass and a flashlight first.

Looking at the gradually darkening night, Li Hua sat down on a big stone with his head down. Anyway, I can't get out tonight, so instead of wasting my energy around the barren fields, it's better to sit here and rest first. As soon as the morning dawns, you will not get lost if you follow one direction at will.

Li Hua stood up and looked around for the sake of safety, and found that the surroundings were really deserted. If he slept here, it was estimated that there would not be any immortal cultivators who would come here to sneak attack, at most, a few beasts would wander back and forth.

After thinking about it, Li Hua released a part of his spiritual power, and covered his body with a spiritual power protective body aperture, emitting a faint green light, the color was very light, and he couldn't even find a shadow. There are small Chinese pinyin letters looming above the aperture, and you can't see it if you don't look closely.

With this aperture, Li Hua can be considered safe this night. It didn't cost much spiritual power to create such a small spiritual power protective body aperture, and it was no problem to support it for a night.

In this way, those beasts that have not cultivated will flee as soon as they come into contact with spiritual power, and they will definitely not come to disturb his sleep.

After making sure that nothing was wrong, Li Hua stretched his waist and prepared to lie down on this big rock and sleep for the night.

Unexpectedly, before Li Hua's body could lie down, a slap hit him on the neck from behind.

Li Hua only felt anesthetized all over his body, he couldn't use his strength, and the world was spinning in front of him for a while, and then he lost consciousness.
