This is a large list of bonus items of fairly good quality, which is enough to kill people who have difficulty choosing.

Fortunately, Levi didn't have this problem.

He directly exchanged for a C-grade gene fluid, a C-class flesh core.

The former, he plans to use it to continue to strengthen his physical body, and strive to enter the level of extreme tempering as soon as possible. And the latter, of course, was prepared for the Book of Ten Thousand Laws, and he planned to unseal the new pages. Hopefully, the new page will give him a powerful enough ability, or give him a chance to level up the Demon Hand or Sharingan.

The remaining points, although not enough to change a C-level gene fluid, are still no problem to change to a C-level flesh core, and there will even be a little surplus.

However, Levi thought about it for a while and did not change it that way.

He valued something else.

A book called "Primary Energy Bullet Engraving Technique".

Levi was very impressed by the box of light engraved bullets that Erin gave him when he hunted that low-level vampire in the first place. Although, he was not able to kill the vampire directly with seven bullets in one magazine, but he definitely injured him severely.

Otherwise, with Levi's strength at the beginning, no matter how good the vampire was, he would definitely not be able to defeat him.

In the later battle, the battle with Zhang Zongming made Levi see how powerless ordinary firearms are against the Evolver.

It is precisely because of this that in the battle with Kuyes of the Skull Party, except for the gun used when dealing with those horse boys, when he really fought with Kuyes, the pistol was put back in his pocket and did not move.

This is not a good thing.

Relatively speaking, in fact, firearms are a very important means of fighting for Levi. In his previous life, he dominated the army and was known as the elite, on the one hand, relying on excellent melee combat skills, and on the other hand, he was far beyond the level of firearms used by ordinary people.

If such a useful weapon is abolished, Levi's combat power will be greatly affected.

And the solution is not impossible, the light engraved bullet that Erin gave him at the beginning obviously showed him a way.

It's just that bullets are really too expensive.

The more than 20 bullets that Erin gave him last time cost 30 aquamarines, and that was calculated according to the preferential price of the Hunter Guild. If you really want to buy it, I am afraid that the market price will have to more than triple.

If you run out and fight, you don't know how much money you have to shoot out just the bullets, it's too expensive, who can afford it? But if you encounter a difficult battle, if you are high, after a battle is over, it is not good to get more bullets that have not been knocked out.

However, if you master the technology to make this bullet yourself, the cost can be suppressed a lot. At least I can afford to use it, and I really don't have any money, and it's always a kind of income to make bullets and sell them.

Therefore, Levi will be interested in this book "Primary Energy Bullet Engraving Technique".

Looking at the price, it's not particularly expensive, it's just a C-grade flesh core.

After changing what he wanted, Levi casually found a seat and waited for the guild warehouse to distribute the goods. This time is about half an hour to an hour, just wait.

After a while, Judith seemed to have all the process done and walked towards Levi.

"What did you choose?" Judith asked, seated across from Levy.

There was nothing to hide, and Levi told her everything he had changed.

"What do you want flesh and blood cores for?"

"I know someone who can make gene fluid, and give me a discount, it's cheaper."

"Then why do you need to change another C-grade gene fluid?"

"People have limited output, and they have to make money, so they can't work for me."

Li Wei had already thought of these statements.

Judith didn't dwell on the issue, but paid attention to the book that Levi had gotten in exchange.

"What do you want to do with this engraving technique book? Do you want to make your own bullets? ”

"yes."

"Tut, there is a future, I am optimistic about you."

Listening to Judith's tone and looking at the expression on her face that wanted to laugh but held back, Levi had some bad premonitions.

It's a good habit not to be ashamed to ask, not to mention that Judith is still a senior and powerful master.

"What's wrong? Is there something wrong with my choice? ”

"Ahem...... Judith coughed lightly twice and said, "Okay, for Erin's sake, I'll explain it to you." ”

"The engraved bullet technology is actually an applied branch of the magic pattern technology, and it is a relatively versatile and basic technology."

"The magic pattern technology is actually an ability that belongs to the chain of will, and if you want to go down this road, the degree of development of this chain of will must be able to keep up."

"Of course, the low-level engraved bullet doesn't mean that you have to open the genetic lock to be able to learn. However, in any case, even for those who have completed the extreme tempering, it is difficult to learn the engraving technique at a low level. ”

"And, most importantly, ......"

As she spoke, Judith looked at Levi and said with some pity: "No matter what kind of magic pattern technique it is, even the most rudimentary carving bullet production technique requires a lot of practice. I'm sure you have the perseverance, but you need materials to practice this thing. Even the lowest level of energy bombs, if you want to learn them, you have to consume a lot of materials. It's a lot of investment, in other words, it's good to have money to play ......"

The words were not finished, but Judith's meaning was also obvious: you poor man dared to jump into this money-burning pit, you really killed yourself.

Seeing that Levi's face had become a little unpleasant, Judith didn't comfort him at all, and continued to stab the knife and said, "Moreover, the formula of the magic pattern is also quite rare. In this primary engraved bullet technique book, if I remember correctly, there should only be a blueprint for the lowest level of piercing bullets. And the price of the formula is very expensive, even if it is a low-level bullet formula, for example, the Light Engraved Bullet that Erin gave you at the beginning, the price of the blueprint of this secondary energy bullet seems to be about equal to a bottle of B-grade evolution liquid. ”

One blueprint equals a bottle of B-class evolution liquid? Are you kidding! Levi's face darkened directly.

"Why didn't you say it earlier?"

Judith admired Levi's face and said very 'innocently': "You can't blame me, you didn't consult me before you changed." ”

Levi was silent for a moment, and said stiffly, "I believe in myself." ”

"Uh-huh." Judith snickered and nodded, "I believe in you too." ”

Levi couldn't stand this woman a little anymore, he stinked face, stood up, and said, "I'm leaving, go back to the lower area." ”

"Eh!" Judith grabbed him and said, "Don't be angry, sit down and sit down, Erin has just contacted me and asked me to tell you something." ”
