Kong Sha wrinkled her nose, took out the human head, turned her eyes around, and nodded in satisfaction.

"Yes, but haven't you gotten rid of the stench on the leather?"

"I'm sorry, senior sister, I've tried several cleaning methods, but I can't seem to get rid of them."

"Forget it." Khonsha looked a little discouraged and threw the leather back into the box.

"I'm going to get out of the tower." Sitting back in her chair, Kong Sha said lightly, "In the next half year, you won't have to send things." ”

Thor stopped packing the box and looked up in surprise.

"Senior sister, you want to get out of the tower?"

Because Thor hadn't seen Khonsha leave the Wizard's Tower in the past three months, he thought that her work didn't need to leave the tower at all.

"Well, my experiments have come to an end, and there's not much progress in staying in the tower. Just right...... Going out can be found in new opportunities. Kong Sha tilted her terrible head, "If you have the opportunity in the future, you can also apply to go out." Even though you're not yet a second-level apprentice, the mentors seem to think highly of you. For those who are capable, they are happy to make exceptions. ”

"Go out......" Thor also wants to go out and see the normal world outside, but he still has a lot of things to learn, and it is not the time for pleasure.

"Senior sister, before you leave the tower, can I exchange something with you?"

Kong Sha threw the human head in his hand, not caring at all about the blood that fell on the ground on his body.

"Swap? Do you have anything of value other than human heads? One of her eyes popped out to stare at Thor's left hand, "If it's your left hand......"

"Well, that's not true." Thor shrunk his left hand into his sleeve, "I've been in the morgue, and I've also saved up some alienation materials, maybe there is a senior sister you are interested in." ”

"Maybe." Hearing that it was not her left hand, Kong Sha was much less interested, and even her eyes retracted, "What do you want to change?" ”

"I want the kind of potion that my sister asked me to experiment with." He paused, and added, "It's the kind that can ablate the flesh and skin, but can control the bones freely." ”

Khonsha's red lips slowly grinned.

"Hehe, haha, hahaha......" She laughed and trembled, and it took a long time to stop, "You little madman, you are crazier than me." ”

Thor thought it was okay, he just wanted to melt his palm, not his brain.

Seeing that Sol was resolute, Kong Sha nodded and said, "Yes, I have a bottle in my hand now." ”

"Senior sister, I want to ask, how long does the potion of a bottle of potion last?"

"If you keep it carefully, it's a month. After that, the effect of corrosion will be greatly reduced, and it will be difficult to ensure the dexterity of the hand. For this little problem, Khonsa did not hide it.

One month? That wouldn't necessarily be enough for Thor to improve his witch body transformation plan.

And Khonsha may not be able to return within a month.

In case she dies outside, where will Thor find such a suitable potion in the short term?

"Senior sister, if I want to change the formula of the potion, is it okay?"

"Yes. Add money! Khonsha said simply, "Are you sure you can afford those odd things?" ”

Thor gritted his teeth and took out a small test tube from his arms.

The tubes are plugged with a wooden stopper and wrapped in an impact-resistant cotton cloth.

The cotton cloth was wrapped in layer after layer, and Thor dismantled it carefully and slowly.

Khonsha didn't take it seriously at first, just sat there leisurely.

But as the contents of the test tube gradually revealed, she slowly sat up straight.

Inside the test tube, there is a milky white cotton thread, quietly suspended in transparent grease.

"What's that?" Kong Sha felt the spiritual power emanating from at least a second-level apprentice from the cotton thread.

"Yes...... West Germany's locator, I don't know if the senior sister is interested? ”

This locator was taken from the back of West Germany's neck during his dissection.

At that time, the diary ran out to warn frantically, and it was not until Thor turned out a bottle of grease and put the cotton thread in it that the scourge was quelled.

This thing is dangerous for Thor, and it has no use yet, so it is best to exchange it for something else.

And because everyone's locator is different, other people's locators can't be used, at most they can be made into props, or borrowed, so its value is not so high.

For Thor, it was worth it to change the potion of Kongsha.

"You're still ...... It's really grateful. Khonsha stood up, walked up to Thor step by step, carefully took the test tube, and held it up in front of his eyes.

A dozen of her eyes were in a circle in a glass enclosure, but their pupils were all facing the test tube.

"He majored in the water element, but the locator has the property of combustion, is this really the locator he chose himself?"

"Can someone else choose the locator?" Thor asked curiously.

"Yes, but it must be someone who knows the apprentice well, even better than the apprentice himself." Kong Sha put away the test tube, then sat down on the test table, took out a pen and paper and began to write.

"Since you are so sincere, then I will not take your things for nothing. This is the formula of the white bone reagent, and the formula that was later improved into the scleroderma reagent, as well as the idea of transforming the formula, I will write it to you. ”

Whew-

The sound of the absorbent pen rubbing against the paper is so pleasant that each stroke seems to be a credit.

Senior Sister Kong Sha is so generous this time?

Thor couldn't help but stand up and lean over to the test table.

It is worthy of the formula of the most powerful second-level apprentice research, and he can't understand most of it!

But it doesn't matter if you can't read it now, just learn it.

With his current ability, status, and backer, the last thing he is afraid of is to waste time on studying.

When Khonsha finished writing, she stood up, her fingertips running over the junction between the white paper and the spine, and then she tore off the page neatly, flicked her fingertips, and flew to Thor.

Thor stretched out his left hand, carefully took the paper full of formulas, folded it in half twice, and snuggled it into his arms.

"I have some materials here, you can make a verification on the spot."

"No need, I believe in Senior Sister." Thor patted his chest as if there were a thousand magic crystals in there.

"It's not a good thing to trust others so much, aren't you afraid that I'll hurt you again?" Khonsa wasn't Byron, and she didn't like to trust unconditionally.

But Sol raised his head and said with a smile: "At present, the senior sister has harmed me, and the benefits of normal exchange with me are not as big. Good wizards value profits. ”

Kongsha stuck out her tongue and licked her lips, "You're only twelve years old, and when you grow up, I don't know how many people you're going to harm." Byron's humble encounter with you, I don't know if it's his luck or misfortune. ”

"......" Saul felt wronged.

In fact, that's how he grew up.

IQ has long been frozen the moment he came into this world.

After the exchange, Thor prepares to leave.

He politely said goodbye to Khonsha, walked to the door, and opened it.

Opposite Kongsha's dormitory is also the door of a second-level apprentice's dormitory.

It was the door that bleed bright red blood that activated the diary's death prophecy.

It was also because of the strange blood flowing from that door that Thor knocked on Khonsha's door helplessly.

Now, the door on the other side is still closed.

Thor's hand pressed the doorknob that Kong Sha had just changed, and suddenly asked in a low voice, "Senior sister, I have a question that has not been answered...... Who's living across from you? ”

Hearing this, Kong Sha still stood behind the experimental table, her red lips raised slightly.

"Who knows."
