"What's changed? That's an increase!" Burning Hands has no casting materials, so what's the increase?

Master Tolga blurted out. Gretel lowered his head slightly, with a smile on his lips, and did not refute. The old magician thought for a while and asked again:

"Is there a paper?"

"It hasn't been published yet."

"Who is your teacher?"

"I'm studying at the Mage Tower in Heartland City, and I'm currently in the training class of the Magic Council..."

Oh, he is a good and qualified seedling, and he has not been trapped in his home yet. Master Tolga once again looked deeply at Gretel and looked at the test tube in his hand:

"What is this gas? Can you let me try it?"

"This is the only one left. I didn't bring enough materials, so I only made this one tube."

Grete spread his hands. The old magician hesitated for a moment. Between "not asking about other people's magic" and his daughter's life, he chose his daughter in the end. He dug into the sleeves of his robe, took out a small silver bell, and put it on

On the table, pushing towards Grete:

"Sorry - what material is it?"

Potassium permanganate. Oh no, what is it called here... Master Lin En mentioned it once... That's right!

"Purple scale stone!"

His eyes lit up, and he was full of joy that he "finally remembered it." The corners of his mouth turned up. The old magician immediately looked at Elder Wood, who shook his head: "No."

There is really nothing we can do if we don’t have it... Master Tolga sighed. Seeing that Gretel didn’t even look at the bell on the table, he simply picked it up and put it into Gretel’s hand:

"Then use your own method! I'm begging you!"

The two old men and the young man joined forces again. Elder Wood was responsible for the vines and summoning the gas, and Master Tolga was responsible for controlling the bubble and making it shrink slowly. Gretel was responsible for shouting next to him:

"Slow down! Slow down! Don't shrink the bubbles so fast! If you beat it too fast, your intestines will burst. Slow down!"

500ml of oxygen - even if it is not pure oxygen, it is air containing high concentration of oxygen - is slowly pumped into the intestines. Theoretically, oxygen can be given at a rate of 5l/min, but that is a vine, not a gastrointestinal endoscope, nor

He couldn't see what was going on in the intestines. Gretel was really afraid that the vine's exit would be in the wrong direction and spray directly on the intestinal wall, causing a perforation or something...

When the time comes to perform surgery to replenish the intestines, not to mention the trouble, there will be a lot of complications and sequelae. Alas, it is better to go slowly than to hurry. Anyway, it is not a big deal to keep more oxygen in the gastrointestinal tract. Even if the intestinal wall absorbs oxygen, it will only absorb oxygen at most.

Only a tiny bit is absorbed.

Woohoo, when will I be able to develop a magic or divine skill and use it as a telescope...

Gretel added another item to his list of needs, watching the old magician deliver oxygen little by little at his greeting. In less than ten seconds, the painful look on Iris's face had visibly eased.

Come down.

"I don't feel any pain anymore..."

"Lie down! Lie down!!!" Gretel jumped up and held her down. Don't drop the gastric tube!

After infusing oxygen, the stomach tube was pulled out - or the stomach tube retracted on its own. After another fifteen minutes or so, Elder Wood activated his magic and detected the breath of life. Under the light of spiritual light, he immediately said "Eh"

One sound:

"They are almost dead! Little Grete, the effect of your gas is much better than the pills! - The stomach is also a little flat and not so bulging..."

That's it. Grete clapped his hands with a relaxed expression, as if he had been working hard all day and wanted to brush away the unnecessary dust:

The delivery of oxygen through the gastrointestinal tract for deworming has been confirmed by many cases and papers. Especially for biliary ascariasis, when the patient is in excruciating pain, a gastroscope is inserted to give oxygen for a few seconds. The effect is immediate!

The patient felt no pain on the spot and immediately reviewed the B-ultrasound and found that the roundworms had been eliminated!

As for my belly not being so bulging anymore...

Adult bugs will stop clumping together when they die. When they spread out, wouldn't their stomachs become flatter?
