One hundred magic cores can be engraved in half a minute, or it won't take too long for all the magic cores to be engraved.

The purchase price of a magic core is twenty-five copper coins, and one hundred is exactly two thousand five hundred copper coins, which is equivalent to twenty-five silver coins, and the income is quite considerable.

But it's still too much of a loss to sell the magic core like this, after the inscription is over, Gao Feng picks up the magic core again, and pours magic power into it one by one, and it takes about two minutes to pour one piece, a hundred magic cores, and it took almost three hours to complete all the infusion.

At this point, these 100 magic cores can be regarded as a truly finished product.

The price of the magic core, which is infused with magic power, is different, the market price is 60 copper coins, and the purchase price of the store is almost 55 copper coins.

In other words, the price of a magic core that costs twelve copper coins has risen to fifty-five copper coins after inscription and demon replenishment, and the net income is forty-three copper coins.

One hundred magic cores, each of which earns forty-three copper coins, and the total income is four thousand three hundred copper coins, which is equivalent to forty-three silver coins.

Gao Feng silently calculated, his own technology has become more and more mature, without delaying meditation, it should be no problem to make two hundred magic cores a day, the income of one magic core is forty-three copper coins, and two hundred is eight thousand six hundred copper coins, and the income is quite good.

The benefits are good, but the workload is also quite large, and you have to spend at least ten hours a day to complete the job.

The 100 mana cores have been made, and Gao Feng handed them over to Harry for Harry to take to the store for sale, and by the way, he bought the half-finished mana cores.

Is the purchase price of 100 Mana Core stores 55 copper coins, sell all of them to get 5,500 copper coins, and the semi-finished magic core costs 12 copper coins, Harry bought 400 semi-finished magic cores at once, paying 4,800 copper coins, and only 700 copper coins remain.

After the half-finished mana core was delivered to his home, Gao Feng continued to make the mana core, while Harry hurried to practice magic.

Just a few days ago, Harry had finally broken through the bottleneck of a third-level magic apprentice and advanced to a fourth-level magic apprentice, much to Harry's delight.

You know, because Harry's qualifications are too poor, he has been stuck in the third-level magic apprenticeship for five or six years, and Harry is afraid that he will be stuck on this joint for a lifetime, so in his usual meditation practice, he is very lazy, if it weren't for Gao Feng urging him to practice magic, he would have wanted to sleep and didn't want to meditate.

This time, he finally broke through the bottleneck of the third-level magician apprentice and reached the realm of the fourth-level apprentice.

Once the bottleneck was broken, the follow-up cultivation immediately accelerated, and Harry also saw the hope of cultivation, and secretly worked hard to cultivate.

Speaking of which, Harry's family background is good, so when his parents were still there, they also invested a lot of money in order to cultivate something, but it's a pity that Harry is not angry, and he spent a lot of money, but it had no effect, so it can be said that it was all wasted by Harry.

Under normal circumstances, if those wasted resources were used on the rest of the magic apprentices, I am afraid that they would have reached the level of a one-star magician, but Harry was stuck in the third-level apprentice and had no progress, which was really disappointing.

It can be seen from this that Harry's qualifications have become worse.

As the saying goes, it's not that a family doesn't enter the door, Gao Feng Harry, a pair of difficult brothers, is really a family, the qualifications of the two are extremely different, and these two magic apprentices with poor qualifications have come together.

Harry's qualifications are poor, but Gao Feng's qualifications are also almost the same, since he became a magician apprentice, Gao Feng has been in cultivation, but he has not been lazy for a day, he is so diligent in his cultivation, and the magic power in Gao Feng's body has also increased extremely slowly.

It can only increase little by little every day, and if you want to advance to the second-level magic apprentice, you will have to cultivate for at least a few years.

According to this kind of cultivation progress, cultivating with normal cultivation methods, I can't say that in this life, I can't cultivate a one-star magician, maybe I can only be a magic apprentice in my life.

Don't think that this kind of thing doesn't happen, in the world of magic, it's very common.

According to the statistics of the Magicians Association, the success rate of one-star magic is about five in a thousand, that is, out of a thousand people, only five people have a chance to advance to a one-star magician.

The remaining nine hundred and ninety-five people will all be stuck in the magic apprentice realm, and they can only be magic apprentices for the rest of their lives.

It is not easy to advance from a magic apprentice to a one-star magician.

And once promoted to a one-star magician, the strength and status will also undergo earth-shaking changes, you know, magic apprentices do not have combat magic, and only one-star magicians can start to learn combat magic, and only then can they have the ability to fight, just for this point, you know the preciousness of one-star magicians.

In the case of Gao Feng and Harry, it is very difficult to cultivate to a one-star mage by relying on their own efforts, and even if they can succeed, it will take a long time.

That's a no-no.

Fortunately, there is not only one way for a magician to cultivate, in addition to meditation and cultivation, he can also rely on external forces to accelerate the effect of cultivation.

This method is nothing more than two or three ways, one is to take some heavenly and earthly treasures, such as the dragon's heart blood, such as the phoenix's bone marrow, such as the ten thousand years magic crystal lotion, and other precious heavenly and earthly treasures, taking these treasures, you can increase your cultivation.

It's just that these treasures are too cherished and can't be found, and under ordinary circumstances, these treasures can't be obtained, so this way can only be used as a reference, not really implemented.

Second, you can use the magic array to accelerate your cultivation, but the magic array that can accelerate your cultivation is all a high-level magic array, and only the big families have the ability to arrange such a magic array.

Third, you can use powerful magic weapons to speed up your cultivation, but this kind of magic weapon is extremely precious, and it is also hard to find, at least at the current peak, you can't get these magic weapons to accelerate your cultivation.

Now there is only one last method, and the only feasible method, which is to take potions to speed up cultivation.

There are two branches of alchemy, one is magic and the other is potions, and there is a big reason why magic potions can become the two pillars of alchemy.

One of the biggest reasons is because the potions made by potions have the effect of speeding up cultivation.

And the two of them want to improve their cultivation progress, and the only feasible plan at the moment is to take potions.
