Chapter 228 Knowledge Exchange

Above the new barrier, Roque looked at the battle before the barrier with a slightly gloomy expression.

"The fighting power of these races is so weak, shouldn't they be civilians?" he asked.

It's no wonder that he has such an idea, except that some guys with mounts are stronger and their fighting power is comparable to that of knights. The strength of other miscellaneous alien races is probably only apprentice knights, or not even apprentice knights.

This is today's enemy, some new races and aliens, they were stopped by apprentices before they even reached the gate.

"In fact, there have been some in previous battles, not civilians, but aliens with extremely low bloodlines.

Don't forget, nominally speaking, they are the invaders, and everything we do is to guard the plane front and protect the civilians in the wizard plane. "

Seeing his strange expression, Grace said with a sneer.

Er, that's right, the Nine Rings Plane invaded the Wizard Plane on its own initiative, and opened up three battlefields in succession on the Wizard Plane, and this is the last one opened.

"Yeah, no one is innocent when you step into the battlefield of the plane, it's just that you stand at different angles." Rock nodded, and he was just thinking about it in his previous life, which made him feel a little uncomfortable.

"It's just that this kind of foreign race with low strength and weak fighting will makes people not arouse the interest of killing." He continued to sigh.

Including Roque, many apprentices know that there are wizards who have studied it for a long time. Deep in the blood of the Nine Rings alien race, there is a deep-rooted influence that affects the will of the alien race and drives them to step into the battlefield of the plane. Like some kind of instinct.

The higher the bloodline level, the deeper the influence of will, which is reflected in some aspects, such as they are not afraid of death in the battlefield, for example, they will find reasons that suit themselves and force themselves to step into the battlefield.

This point, under the influence of the blood, the foreign race will never be able to notice it.

"Captain, Buhler's materials have been transported to Guansai. Now that you have time, should you teach me how to make gas bombs?" Grace urged, changing the subject.

None of the captains participated in the killing, and they were surrounding Captain Rock to inspect the fortress. When they heard what Grace said, they all pricked up their ears.

"Didn't you check it yourself?" Rock asked back.

"I didn't have time in the battle before, and then I thought that you would have to teach me sooner or later. Why should I risk violating the contract and use my mental power to explore such a horrible thing?"

Grace answered his words frankly, and the others nodded in agreement, and at the same time showed their innocence.

Believe you are a ghost!

However, he has already taken out the gas bomb, so it is impossible to keep it secret. Although he has mixed some cover-ups in the production process, the principle is actually very simple, and the engraved symbols are also very simple.

He wanted to gain more benefits in the plane battlefield, so he had to teach some people how to make more gas bombs and put them into the next battle.

"Knowledge has a price, you should understand, what is the value of the method of making gas bombs? You are more experienced than me, you can judge for yourself." Rock was happy to pretend to be confused, and then changed his voice, and continued.

Hearing his words, the eyes of several people lit up. In their view, the exchange of equal value is normal, which did not surprise them.

"I don't think you need anything else. I'll give you a bottle of top-level boiling blood potion." Grace waited for his words and said before anyone else could speak.

do as promised,

She directly took out a test tube. Inside the test tube was a lava-like liquid medicine, which was maroon and crimson, constantly tumbling.

"make a deal."

Rock didn't say anything, and handed him a one-time witchcraft crystal.

Witchcraft crystals have a lot of background. They were produced by an organization called the Witchcraft Research and Secrecy Association. Using witchcraft crystals to record the production method has an additional advantage. The crystal comes with a contract, and Grace cannot pass on the production method to others. one person.

Once someone breaks the contract, there is a 1/39.9 probability of making a mistake every time a witchcraft is performed. No one wants to add an unstable factor.

After the exchange between the two, Gray unceremoniously activated the crystal, incorporated the knowledge in his mind, and immersed himself in the production method.

A gas bomb production recipe, including three mixed metal recipes, three mixed poison recipes and production recipes.

After more than a minute, she stared at Roque.

"No wonder the instructor praised you so much. You are so unusual. It is a complete innovation. I felt weird when I used the gas bomb before. That's why."

Grace sighed, in her opinion, although the method of making gas bombs is simple, the knowledge contained in it is immeasurable, which gave her a lot of inspiration and gave her a lot of inspiration at once.

When she said this, the other captains felt even more itchy, and became more enthusiastic about the production method.

"Captain me"

The next moment, the three of them spoke at the same time, stopped after half a sentence, and glanced at each other.

"You two big men, you won't bully a little girl like me." Rita put on a pitiful look, looking at Lied and Wao.

Even though she knew she was faking it, and she said so much, the two still gave it a face.

"I've seen the captain's sorcery, and the other three belong to the top level. The only thing that is lacking is the speed-up sorcery. I happen to have a top-level fog dexterity improved model in my hand. I don't know if the captain will like it? "Rita took out a witchcraft crystal at random.

"Of course, but the production method will have to wait until tomorrow, and I will re-burn it." Naturally, Rock doesn't dislike it, and now he can make up for his shortcomings in witchcraft.

After a while, he realized the new witchcraft, and it was really worth the money.

Like the magnetic gold shield, the new witchcraft is optimized on the dexterity of the fog, and newly added thunder particles, which greatly enhances the burst speed, and is called the fog spirit flash.

When he was studying, he only needed to optimize the original witchcraft model without spending too much thought.

"Not bad, it really suits me." He praised, and his sense of Rita improved a lot.

Now, the other four captains hesitated. The two of them were top-level resources when they made a move. The things they brought out must not be bad, and it is best for the captain to use them. The range of choices is much smaller.

Fortunately, all three of them were veteran fifth-level apprentices, and their accumulation of resources was far beyond what Rock could match. Lied also took out a top-level blood-boiling potion, and Wao and Oliver each paid for a medium-level nectar potion.

"No problem, after I re-burn it, I will give you the recipes in order."

Rock responded one by one, and his heart was full of joy. He couldn't help feeling that selling knowledge is the most profitable, but it's a pity that it is extremely difficult for black witch apprentices to apply for patents.

The nectar potion is not an ordinary potion, it can be used to heal injuries, restore physical strength, replenish vitality, etc., and is selected as a commonly used advanced potion for wizards.

Behind them, many fourth-level apprentices looked at the captains resentfully. They raised the value of the gas bomb manufacturing method so high that the price they had to pay was beyond their ability to afford it, and they canceled most of the people's exchange plans at once. idea.

For this, Rock had expected it a long time ago, and he even hinted to Grace that in order to learn how to make gas bombs, Grace made a perfect cooperation.
