For a week after the start of school, Mr. Bai was teaching some basic knowledge. The main purpose of the Chinese class is to allow students to flexibly use 23 initials and 24 finals to enhance their spiritual power, and the main purpose of the mathematics class is to let students type addition formulas within 10.

Unlike other classes, Ms. Bai pays special attention to the improvement of spiritual power, so at the beginning of the first grade, she taught the students the Chinese pinyin table, which should have been mastered by the second grade students, so that they could stabilize their spiritual power early. As for the improvement of mana, Teacher Bai doesn't pay so much attention to it, other classes have begun to learn subtraction within ten, and Teacher Bai still only lets students practice addition within ten.

Many classmates were dizzy by the Hanyu Pinyin Table, but Li Hua was the opposite, he was able to enjoy the pleasure of learning the Hanyu Pinyin Table to improve his spiritual power.

For a week, Li Hua used an iron box every night to upgrade ten pieces of low-grade fruit candy, and then did some experiments that he thought might be successful.

Through a week of experiments, under countless failed experiments and considerable losses, Li Hua has basically figured out the rules of use of the iron box.

Because the iron box uses the power of moonlight to upgrade magic weapons and medicines, Li Hua also gave the iron box a nice name, Moonlight Treasure Box.

The effect of the moonlight treasure box is indeed not small, and it can give Li Hua a lot of benefits, but it also has many taboos, and there are some rules, which must be repeated experiments to be able to draw conclusions.

First of all, everything that is put in it must be magic weapons or medicines, otherwise, it will be like Li Hua, when the lid is opened, a black smoke erupts from the pavement, and everything that was originally put in is burned;

Secondly, the things put into it must be of the same grade, otherwise the high-grade things will not only not be upgraded, but will also devour the low-grade things;

Again, the things that are put in can only be improved by one grade, and repeated inserts cannot be improved by more grades, and only when two things are put in and these two things can be fused, the product of fusion can continue to be improved by one grade. As for how many times it can be fused in total, and whether it can improve the grade every time it is fused, this is what Li Hua's experiment has not yet taken into account;

Finally, there is the capacity of the moonlight treasure box. You can put up to five things of the same kind, and if you put too much, you will be devoured, and you can only put two kinds of things of different kinds, and if you can't fuse, the grade will not be improved, even if you have never put something in the Moonlight Treasure Box, you can't improve.

In addition, Li Hua also mastered the time it would take to upgrade these things. Being able to understand so much in a week, it can be seen that Li Hua has also worked hard.

Of course, the pay and return are directly proportional to Li Hua's body.

Li Hua used the spirit stones sold by Yipin Fruit Candy to buy some Yipin Zhenzhi Stick and Yipin Alpine Candy. Compared to a spirit stone that can buy ten pieces of low-grade fruit candy, this True Knowing Stick and Alpine Candy are really valuable, and each of the True Knowledge Stick and Alpine Candy is worth five spirit stones!

In order to quickly improve his cultivation, Li Hua was really ruthless, in addition to spending spirit stones on those necessary experiments, almost all the remaining spirit stones were bought with true knowledge sticks and Alpine candy. A total of ten True Knowledge Sticks and ten Alpine Candy were bought, and a hundred spirit stones were spent.

Now that he has the Moonlight Treasure Box, Li Hua is not very short of spirit stones for the time being, and his life has become rich all of a sudden. Every thirty minutes, he can upgrade five pieces of low-grade fruit candy, the cost is almost negligible, and now he has found a long-term cooperative shop, a piece of one-grade fruit candy can be exchanged for two spirit stones, and other raw materials purchased can also be discounted. In this way, his income is even more impressive.

Li Hua according to the work rules of the moonlight treasure box, reasonable planning of his own application of the moonlight treasure box, every afternoon after school, after buying raw materials, immediately after returning home, use two hours of time to upgrade twenty pieces of low-grade fruit candy, and then upgrade the first product of Zhenzhi stick and Alpine candy for one night, and use eight hours to upgrade them into second-grade pills.

These second-grade true knowledge sticks and Alpine candy can be sold for twenty spirit stones each. Li Hua can upgrade five second-grade pills every night, can sell one hundred spirit stones, can upgrade twenty first-grade pills every day, can sell twenty spirit stones, and can sell one hundred and twenty fast spirit stones per day, in addition to the capital, Li Hua can probably earn a hundred spirit stones every day.

Such a huge number makes Li Hua steal fun for a long time every time he thinks about it, the minimum salary of a primary school teacher is 3,000 spirit stones a month, but Li Hua, who is a primary school student, can also have this income, which is really enviable. In the past, it took two years to save two hundred spirit stones in order to save up the tuition fees for the first year of school, but now, two days are enough.

Thinking of the past, Li Hua couldn't help but regret a little, and his intestines were all repentant, how good it would have been if he had discovered the wonders of this moonlight treasure box earlier!

But after thinking about it, he couldn't even endure those hardships, and he couldn't stand those sins, and he must not be able to persist on the road of cultivating immortals. And now, his will has been sharpened by suffering, far from being a fragile little child.

After a few more days, Li Huacai was arrogant, and he carried out an experiment beyond his ability, he wanted to fuse the second-grade true knowledge stick with Alpine candy and upgrade it to the third-grade Alpine true knowledge stick.

You must know that his cultivation can only allow him to sense the aura of the second-rank pill! Now he doesn't know how long it will take to upgrade from the second-grade pill to the third-grade pill, so he can't be sure if the pill he got is the third-grade pill. If the pill is between two grades, the efficacy will be the same as that of the lower grade pill, which is equivalent to wasting time.

Although it was very risky, Li Hua refused to let go of such an opportunity to quickly improve his cultivation, and based on his experience that it took thirty minutes for a lower grade pill to be upgraded to a first-grade pill, and eight hours for a first-grade pill to be upgraded to a second-grade pill, the time for a second-grade pill to be upgraded to a third-grade pill might be sixteen times that of eight hours, that is, one hundred and twenty-eight hours.

To be on the safe side, Li Hua decided to open the box after one hundred and thirty hours. Every day, he can make the moonlight treasure box for up to ten hours to receive the purest moonlight, in fact, in the twenty-four hours a day, only ten hours of moonlight can have an effect on the moonlight treasure box.

In this way, it would take thirteen days before Li Hua could get this three-pin pill. Although it took a long time, as long as the effect was good, Li Hua's hard work was not in vain.

In the past thirteen days, Li Hua has not cooperated with the store anymore with a single fruit candy, so he has to temporarily stop using the moonlight treasure box and practice the content taught by the teacher in class with peace of mind.

Li Hua was able to cultivate diligently in the thirteen days without pills, so he ate all the remaining nine True Knowledge Sticks and nine Alpine Candy.

The effect of the eighteen first-grade pills was still obvious, Li Hua used the spiritual power in his body, and after a little digestion, he felt that his originally shallow cultivation had broken through the realm of the early first grade, and his body was immediately reborn, and the spiritual power in his body that he could perceive had increased a lot.

Even so, Li Hua still couldn't perceive the Sanpin Pill, and he could only perceive it when he broke through the realm of the middle of the first grade.

While his cultivation has improved, Li Hua is excited and at the same time, he also has more time to practice the two basic subjects of mathematics and Chinese.

Through unremitting practice, in these thirteen days, Li Hua has roughly mastered the Chinese Pinyin Table, and while being able to stabilize his spiritual power with twenty-three initials and twenty-four finals, he can also use pinyin letters to attack people.

In terms of spells, Li Hua has also made obvious progress, and he can already master the addition formula within ten, and the subtraction within ten can also pass the test so-so.

Of course, Li Hua never let anyone know about these improvements, and only practiced by himself when he went home.

Li Hua in the class has always been very low-key, at first Teacher Bai went to ask Li Hua if there was anything he needed help, but later he lost confidence in him, and he didn't even bother to criticize. The classmates were even more indifferent to Li Hua, as if there was no such person in the class.

Ma Luyang secretly observes whether Li Hua has made progress every day, although she cares about Li Hua very much, but she is embarrassed to always ask Li Hua about his situation. She knew that Li Hua was a strong boy and didn't like others to interfere too much in his life.

Li Hua also knew that Ma Luyang was silently caring about him, he had all of it in mind, and when he could show his strength, he would definitely make Ma Luyang happy. But now is not the time, so I have to treat Ma Luyang's concern as if I didn't see it, so as not to attract the dissatisfaction of other boys and unnecessary disputes.

Finally waited for thirteen days, Li Hua didn't dare to breathe and opened the moonlight treasure box, staring at the rich air in the box with bright eyes slowly dissipating, the first thing that caught his eye was a purple plastic stick, looking up along the plastic stick, the original green Zhenzhi stick had been fused with the blue Alpine candy, blue and green were staggered, and the color was very beautiful.

Li Hua hurriedly took out this Alpine True Knowledge Stick, and just about to inject the spiritual energy into it, he found that the spiritual energy in it was too powerful, and there was even a gravitational force that wanted to eat the spiritual power in his body.

With courage, Li Hua took this three-pin pill.

As soon as he swallowed it into his stomach, Li Hua felt a wave of overturning in his stomach, followed by a burning sensation, and the whole person seemed to be buried in a sea of fire, sweating profusely and panting.

This must be the reason why the spiritual power of the Sanpindan is too strong, Li Hua sat cross-legged, closed his eyes tightly, gritted his teeth, and operated the Hanyu Pinyin table in his body to stabilize his spiritual power.

The fiery feeling lasted for more than half an hour, and as soon as the fire in his body subsided, Li Hua opened his eyes, was stunned for a while, and laughed loudly: "I didn't expect that I had forcibly broken through the realm of the middle of the first grade, and in less than a month after entering the school, I had broken through the realm of cultivating immortals twice in a row, who would dare to look down on me?

Taking advantage of the great increase in cultivation, Li Hua didn't sleep all night and was immersed in the magic of mathematics. By the time dawn came, he had mastered all the addition and subtraction within twenty.

Although Li Hua's cultivation is not yet at the top of the class, it is no longer a problem to enter the top ten.

When he was in school, Li Hua suddenly showed a smile, "It's time for me to let Ma Luyang see some of my strength, so that she can also know that I, Li Hua, am an upright and hot-blooded man, not a coward!"
