It's not that hard to open a hospital in another world, right?

Chapter 1121 I measured, I proved, I advanced! (Double monthly ticket for ticket plus change)
Gretel's experiments were carried out step by step and non-stop.

Thyroids from rabbits were dissected, minced, ground, and dissolved in distilled water.Use the magic circle invented by Mr. Norwood to extract potassium iodide——

"This is it! This is it!"

Cerilla glanced over, pointed at the collection end of the magic circle and shouted:
"The light inside is the brightest! Once this is collected, there will be no light next to it!"

Gretel: "..."

It is really good to have a dragon!
It's really convenient!

You are struggling to take the test with the instrument, and you have to repeat the test, and you have to change the way to test, and you are afraid that your hand will slip and miss the test.Oh, and if there's no way to detect it, you'll have to invent it from scratch...

And here, I only need Serila to take a look!
Gretel quickly experimented and quickly recorded:

"It is known that the magic circle invented by Mr. Norwood can only extract the same substance as set. The target substance set is potassium iodide, and the extracted substance must also be potassium iodide;"

"Extract the elemental iodine in potassium iodide tablets and the elemental iodine in the rabbit's thyroid gland. Both are purple-black crystals, easy to sublime, and easy to condense after sublimation..."

"Testing chemical properties separately...reactions with metals...reactions with non-metals...reactions with water...can show a variety of oxidation states from -1 to +7...It can be proved that the two Elemental iodine has the same chemical properties..."

"Physical properties..."

When Gretel wrote here, he paused, his heart beating wildly.The most intuitive difference between iodine in kelp and iodine in rabbit thyroid is that one is not radioactive, while the other is radioactive;
And delving into the reason...

According to the previous life, the number of protons in the nucleus is the same, but the number of neutrons is different;
And this world, the magicians, have just explored the atom, and have not continued to go deeper. ——Or, before Gretel left the Eagle Country, the papers published by the parliament did not involve the mysteries inside the nucleus.

It can be proved that there are two kinds of elements in this world, which have the same chemical properties, but are different in radioactivity, which is equivalent to half-opening the door of the atomic nucleus!
He held his breath, set up a magic circle, and began to measure the physical properties of this iodine element.Melting point...Boiling point...Water solubility...Density...

Different densities!

The readings of the magic circle are clear, the density of radioactive iodine and non-radioactive iodine has a very small but definite difference!
"...Through the above methods, we can prove that the same element may have different atoms...For example, another iodine discovered by the author can emit rays continuously..."

"Given that they have the same chemical properties and are in the same position in the chemical sequence, the author temporarily named this similar element [isotope]..."

"I hope that the study of isotopes can reveal more mysteries inside the elements..."

Gretel squeezed the [Endless Ink Pen] tighter and tighter.The Lord of Thunder had already been able to perceive electrons before, and a further step was to perceive electrons in atoms.

Then, if he gets the isotope again and personally perceives the rays emitted by the radioactive isotope—I hope he will take good protection and don’t directly pick it up with his body—maybe this legendary boss can directly feel the protons and neutrons The presence?
At that time, what kind of changes will occur in this world with magic, divine arts, and legendary mages?Maybe, the teacher will be able to rub the nuclear bomb with his hands after studying it?
Cerilla dangled back and forth outside the research room.Although I wanted to poke my head over his shoulder to see what he was writing, I still couldn't bear to disturb him:
Looking at Gretel's face, it seems that he is writing an important paper?
It will be the same later, don't make any noise to interrupt his train of thought...

"Cerilla, what's the matter?" Ms. Jasmine walked over from a distance while she was idling around, and waved to her with a smile.

In the past few days, Mr. Hawthorne was instructed by You Dian before he left, as if he had touched the threshold of advancement, and he was practicing desperately; Ms. Jasmine was free to give to the elders and Anirui Lin Ge started.

It was almost lunch time now, and she was about to cook with a basket full of layers of mushrooms on her arm.Seeing Cerilla wandering outside the laboratory, I turned around and chatted with her:
"Why stand here in a daze? —Grete won't disturb you?"

"He's writing a thesis...don't let me play with those things, it's so boring..."

"Hey, there's no way to write a thesis." Ms. Jasmine automatically ignored the proposition "What exactly is Gretel not letting Cerilla play with?" and came to hold her hand with a smile:
"Come and see, what do you want for lunch? I picked very fresh mushrooms... Do you want grilled mushrooms, baked mushrooms with cheese, or mushrooms stuffed with ham?"

While speaking, the two walked forward side by side, and they had already gone seven or eight steps.Suddenly, Cerilla let out a "huh" and stopped to look back.At the same time, Elder Fahim hurried over:

"What's wrong?!"

"It's nothing..." Ms. Jasmine replied reflexively.Halfway through speaking, he followed Serila's gaze and froze on the spot.And the next moment, Anari Linge also rushed over:
"What happened!"

"Gretel...Gretel..." Cerilla's silver-blue eyes opened wide, and the tips of her ears trembled slightly.However, there was no panic in the silver dragon girl's voice, instead it was full of joy, and she almost jumped up clapping her hands:

"Gretel is about to advance!"

Finally going to advance!

Alas, she has been waiting for a long time... From the country of eagles to here, she has traveled thousands of miles and dawdled for a whole dry season, and now the rainy season in the rainforest is almost over...

If you don't advance, a year will pass!

Year after year, she has become an adult dragon, when will Gretel catch up with her!

She shook off Ms. Jasmine's arm and ran towards the research room.Running to the door, he took the shape of a dragon on the spot, lay down on the open space, and covered the mage's hut with his wide wings:
"I won't eat lunch! I'll stay here!"

"This...it doesn't have to be like this..."

Elder Fahim shook his head and smiled.Laughed for a while, waved, and walked back with his disciples and others:

Gretel's advanced spell fluctuations have become more and more intense.He also wants to say hello to the ancient tree, so that it will not be surprised, and cooperate with the diversion force.It's the little guy who is advancing, nothing else!
The people outside are guarding, watching, and guiding.Gretel himself has slid down from the desk in the research room, sat cross-legged on the ground, and entered a deep state of meditation:
Ah, the advancement comes too fast, like a tornado.If he had known this would come out, he would have saved the paper for a while and wrote it under the old tree!

That is the natural mage tower, the natural element collector!
However, this wave of feedback from the world came so fiercely that there was no room for him to adjust—it was like having diarrhea, sometimes even if you wanted to run to the toilet, you might not be able to make it in time.

The same is true for Gretel. Before he had time to react, he was poured down by the world's feedback.That momentum can be described as "split the eight petals of the roof and pour down a bucket of ice and snow water"...

It also has light effects.When Gretel sank into meditation and guided the will of the world, he felt the messy lights and shadows flying in front of him.Whoosh, left, whoosh, right, whoosh, straight ahead...

"Is this a cloud chamber... You guys, are you performing the trajectories of different particles in the cloud chamber in front of me..."

Gretel murmured to himself.Oh, in fact, there are only α-rays and β-rays, and γ-rays basically cannot see the trajectory in the alcohol cloud chamber.

So, is it still time to get the Geiger counter out...

Just walking away like this for a while, Gretel suddenly felt hot all over, and the meditation world also shook violently.He didn't dare to neglect, so he quickly concentrated his energy and accepted the infusion of the will of the world:
The spirit of the whole person rises rapidly.Rise up, rise up, rise up to the heavens that gently undulate and merge with the material world.The higher you go, the clearer the sky is, and the greener the mountains and forests under your feet——

Do not!
What my spirit wants to blend with is not the Emerald Dreamland!
Gretel gritted his teeth, pulled himself together, and forcibly pushed down his mental strength.The Emerald Dream is good, very good, and very beautiful.In my daily meditation and sleep, I am also willing to sort it out, maintain it, and repair it——

However, it is always only a part of this world, not the whole of this world.And what I want to see, what I want to greet, and what I want to accommodate are all the details of this world, up to the limit of my cognition!
"Ugh……"

Far away, under the ancient tree, Elder Fahim sighed deeply.After all, this little guy is still a human magician, not a natural walker of elves——

Little guy, if you want to walk the path of a spellcaster without relying on the support of the Emerald Dream, there will be many difficulties and ups and downs in the future, and you have to overcome them yourself!

"teacher?"

Anairi Linge asked in a low voice.On the brows of the young elf, there was some doubt and worry.The elder shook his head at her, leaning his back against the ancient tree, raised his head and remained motionless:
A generation has a generation's ideas, good luck, little guy...  

Gretel's mental power turned in a direction—this direction is not up, down, left, right, front, back, etc., nor is it a direction that can be marked with latitude and longitude, but a more subtle thing — continue to rise.

The earth spread out before him, and the rainforest stretched beneath his feet.Trees, shrubs, ancient trees; beasts, monsters, birds, fish; lit up bit by bit.

As the spiritual power increases again, the ocean appears in the perception, the distant continent appears, and the continent opposite the ocean appears...

What Gretel paid more attention to was the lifeless scorched blackness under his feet.In the rain forest, with a rising rock mountain as the center, the rocks are cracked, the vegetation is burned, and the strange monsters prey on the deformed mountain forest in the distance.

The location and features of the rocky mountain were similar to those he had seen in the Emerald Dream.The only difference is that above the rocky mountain, above the entire charred area, is covered with a layer——

light.

On the first floor, he can only see the clear light directly with the dragon's eyes.
