Byron was still accustomed to using the place where he was staying as his laboratory, so he took the black powder and went back to his room to study it alone.

Thor greeted the senior he hadn't seen in a long time - although he was no longer as strong as him - and was a day late to see Noah, a young apprentice who had been thrown by him in the Chaos Domain.

The chaotic area is still full of black sand, and the terrain is gently undulating as far as the eye can see, and there is no alpine woodland in sight. Only at the end of the sky can you see some black-gray mountains undulating.

Thor turned around and saw a small crooked house on a small hill.

Or a small shack will do.

The main materials used to build the house were unused shelves that Sol threw at Noah.

Marsh, the coachman, who was no longer in a hurry, provided huge mushrooms, but unfortunately these mushrooms could not thrive in the Chaos Domain. It can only grow to the thickness of an index finger in a potted plant, and it can barely be used to feed the stomach.

Thor walked a few steps to the humble house, and walked around without seeing Noah.

He simply flew into the air, and soon saw the young apprentice working with his head down in a low-lying area in the distance.

Thor flew over just in time to see Noah pull out a dark green plant from the ground, somewhat resembling aloe vera.

"Mentor!" Noah looked up and saw Thor and burst into tears.

The days in the chaotic realm were very difficult, and he wanted to meet other people, but he was afraid of meeting other people. Living alone, apart from sunrise and sunset, there is hardly a sense of the passage of time.

In addition, Sol didn't come over within a month, and Noah didn't sleep well in the past two days, and he was worried that Sol had left himself here alone.

Looking at the teary-eyed little apprentice, Thor also knew what he was worried about, and couldn't help but smile and touch the other party's head.

When Saul flies out of the back of Thor's neck and wraps around Noah's lower abdomen, Thor flies back to his hut with Noah.

"Didn't you build this house using the witchcraft props I gave you?"

Some witchcraft items can also be used by ordinary people who don't have magical powers.

Noah craned his neck, "I, I think it's better to save more magic crystals before getting familiar with this place, so I didn't want to use them." ”

He was a little worried that Thor would blame himself for not trusting him.

But Saul approved of Noah's choice, "It's okay, after all, you live here alone, and it's more important to be assertive." What are you holding in your hand, the plants here? ”

Noah raised his hand, "It's a plant with a lot of water, I tested it with the reagent you left, and it's basically safe, so I want to transplant it near the house and see if I can grow more." ”

Although Thor also left a lot of food for Noah, he is still trying to carve out a new way to survive.

Thor looked at the other things Noah had picked up, a handful of shriveled plants, the remains of some suspected creature corpses, and a lot of useless stones.

Because Noah's knowledge is not enough, Thor does not criticize him, but encourages him to continue exploring, but only if he is safe.

"How many basic runes have you learned now?"

"Three." Noah immediately crouched down and wrote directly on the ground with his fingers.

There is no way to infuse magic power, and there is no way to mobilize mental power, and Noah can only memorize runes by rote now.

"No one knows that they can learn two runes on their own? Looks like you're not badly gifted with graphics. However, when you learn compound runes later, this talent will not be enough. ”

Thor also did not shy away from squatting down, "I'll teach you a method, called the coordinate method, which is convenient for you to remember, and the most important thing is to facilitate your understanding of compound runes in the future." ”

There was no one around, so Thor directly used the earth to make a board book, and combined his experience of learning runes with the experience of casting spells over the years to reintegrate a set of coordinate methods to teach the junior apprentices.

Noah's eyes widened, as if he saw a new world.

After a day spent in a thirst for study, Thor finally told Noah to be careful of monsters, and even more so of intelligent creatures, before leaving the Chaos and returning to the Pure Soul Wizard Tower.

Sensing Thor's return, Hope the butler immediately came to the door.

"Lord of the Tower, Mr. Byron has been looking for you at night."

Senior Byron is actually a very homely person, and he usually doesn't take the initiative to look for anything if he has nothing to do.

Thor hurriedly found Byron, and saw that his room was already full of scratch paper.

"......" Thor stood at the door, feeling like he couldn't get off his feet, "You're adapting so fast!" ”

Byron looked up, not paying attention to Saul's complaint, "You come to see this." ”

When he came to the table, he was shocked to find Byron's hands blistered. Some of the blisters had burst and were still bleeding blue juice.

"Pollution?" Thor immediately frowned.

Byron pointed to the flat parchment on the table, "Look at this." ”

Thor then moved his gaze to the paper.

I saw that the parchment was crookedly filled with words, and at the end came to a conclusion.

…… The formula for black powder (Byron's shorthand for the powder that Thor brought back from the Chaos and has the same source characteristics as Kuroshio) is reversible, and once mastered, it is possible to convert the Kuroshio pollution that is unique to the Borderlands into an inert black powder...... In the same way, it can be seen that the inert black powder can also be restored to active Kuroshio pollution by reversing the formula operation.

Thor's mouth slowly opened wide, he didn't expect Byron to come to such a conclusion in just one day's work.

"Look, is there a problem with my derivation? If you don't see a problem either, then I'll go ahead and derive the formula in that direction. Well...... It's called the inerting formula. ”

Saul looked at the entire formula, and didn't even notice anything wrong with the logic at a glance.

His first instinct was to show it to Camus, but the next second he rejected the idea.

This inertization formula was studied by him and Senior Byron.

He can't rely on Camus for everything, because it will make him lose the habit of independent thinking.

"I don't see any problems at the moment. Or maybe it's too short. You asked me to take it back and study it. Thor immediately cast a Tier 0 replication technique, making a copy of the parchment that did not have any magical attributes.

This was a question that Thor had never thought of, and it immediately intrigued him.

If you can really let the pollution of the borderlands inertize into almost no danger of black powder, then will you be able to prevent yourself and the people around you from alienating the pollution when the Kuroshio really breaks out in the future?

He has had too many things recently, and even if he has already gotten black powder, he has never had time to study it in depth.

As a result, Byron suddenly "snapped" his palm and pressed the parchment that Thor had copied.

Juice splashes.

"No way!" Byron refused to study this subject with Thor, "You have just entered the second order, and your strength is unstable. I've heard Kira-sama mention that entering the second level is different from before, and the knowledge system and world cognition need to be re-improved, and until then, you'd better not participate in any research. ”

Looking at Byron with a serious face, Thor raised his hands in surrender, "Okay, okay, but you better let me treat your hands first." Why is it all hot when you don't see it for a day? ”
