During the float ride, Reiner quickly noticed that this dock was not only for ordinary people to ride on the floatboat, but also for high-level mages to take off, or some mechanical mages to use their own flying props.

Reiner can't fly spells and doesn't have his own flying machine, so he can only fly in a slow floatboat.

He saw that the world already had the prototype of an airplane, but most of these strange-shaped flying machines still imitated the fluttering wings of birds, which was very funny to fly, and the more popular ones were small single-person floating boats, which could only take one person, and the shape looked like a motorcycle without wheels, this kind of flying machine could keep floating even on land, Reiner secretly wrote down the brand, and prepared to buy one to study later.

The float flew for about ten minutes before arriving at the island where the mercury balance was located, according to Reiner's chatter on the float boat, except for the main island, the rest of the airspace of the Rainbow Tower was basically occupied by various legendary mages and powerful academic organizations, and the island where the mercury balance was located was called the fourth area.

The Fourth Sector is the only island with a huge lake other than the main island, so it's also a tourist destination, and the surrounding forests are home to many wonderful magical creatures that attract mages who study them.

Reiner also learned that most of the mages who were riding the float boat together were residents of the island, and there were also a few tourists who had only come to the Rainbow Tower in the past few days, preparing to visit every place, and none of them were destined for the Mercury Balance Headquarters like Reiner.

Disembarking from the floatboat, Reiner took a loop around the island to the headquarters of Mercury Balance.

Located on the shores of a lake, this manor house is architecturally closer to the ancient Magic Empire, and it's no surprise to think that the island was once the capital of the ancient Magic Empire.

"I'm with Eagles. Lord Field has an appointment. ”

Arriving at the gate of the manor, Reiner presented his identification to the man on duty.

The man sitting in the duty room took the paperwork handed by Reiner and carefully checked it before handing it back to Reiner.

"I really didn't expect that in less than a year to meet again, I was still an unknown four-ring mage, and you have become a celebrity who can talk about magic with your Excellency the High Mages."

The mage on duty smiled bitterly, making Reiner a little confused, and looked at the other party's face.

This is a featureless, baby-fat face, and the man looks no more than thirty years old, which is considered young at the level of the fourth ring.

After searching in his memory for a long time, Reiner still didn't remember who it was.

"Uh, excuse me, can you ask where we've met before?"

Reiner asked, deepening the bitterness in the other's smile.

"Ah, well, after all, I'm just a handyman, you can't remember me as I should."

The man shrugged his shoulders and continued.

"My name is Anton, and I was the one who confirmed your invitation at the annual meeting of Mercury Scales."

As he said this, Reiner finally remembered, but he really couldn't remember Anton's appearance, so he only had a general impression.

"I'm so sorry."

"It's okay, please come in, Lord Field's office is in the second room on the left hand side of the third floor, if you can't remember, you can ask the receptionist at the headquarters."

Antun didn't dwell too much on this matter, and with a wave of his hand, the alchemical creatures stationed at the gate made way for Reiner and Claire to pass.

This little episode made Reiner a little emotional, he has made continuous progress for special reasons, but there are many more people in this world, who have always stopped and sighed.

Claire has not shown any signs of advancement so far, maybe she is really not suitable for studying magic, but because she was adopted by the Crescent Moon Academy since she was a child, she will move towards the path of a mage.

Reiner sometimes has to think about a problem, according to the current situation, he may be promoted to the top rank in a few years, and he has at least three hundred years of life, while Claire can only die of old age after a hundred years like ordinary people.

He hadn't experienced the life of an immortal yet, so naturally he didn't have the corresponding experience, and Reiner didn't know if he should make some decisions.

The birds and flowers in the manor were singing and there was no sense of autumn in the slightest, and Reiner and Claire walked into the mansion, the huge room was not a single person, but it seemed to be very lively, and the two went up the stairs to find Lord Field's office.

Upon knocking, Reiner was answered, and he pushed the door open, only to see Lord Field first.

"Reiner, long time no see."

The president of the mercury balance, Frederick. Dmitry was sitting in a chair next to him and greeted Reiner.

"President Dmitry."

Reiner and Claire hurriedly saluted, and then, on the other side, the owner of the office, Lord Field, spoke.

"A handsome gentleman should always be accompanied by a beautiful young lady, and it seems that Reiner knows this very well."

He quipped that Lord Field wasn't seeing Claire for the first time, but he was keenly aware that Reiner and Claire seemed to be a little closer.

Claire, a little shy by Lord Field's words, half-hid behind Reiner and pinched the corner of his coat.

"Your Excellency smiled."

"No jokes aside, Reiner, is this female companion of yours a mage, and can she accept your theories?"

Lord Field asked, and then added.

"Because in other research institutes before, there were intermediate mages who accidentally saw your paper and almost had a cognitive collapse, so we are worried that a similar situation will arise again."

"Don't worry, Lord Field, if there is anyone in this world who can trust me and understand me completely, it must be Claire."

Reiner replied that Claire knew all of his discoveries, and that Claire had been very receptive to new things by Reiner's side for a long time, at least, until the wave-particle duality, Claire was already aware of it.

Hearing Reiner's words, Claire felt shy at the same time, but also a little joy welled up in her heart, she always felt that she didn't give Reiner a lot of help like other students, and felt that she might have dragged Reiner back, but now it seems that Reiner still trusts her quite a lot.

"In that case, let's talk about your paper."

President Dmitry stood up, waved his hand, and a piece of parchment floated from his desk, a copy of Reiner's papers.

At the same time, traces of light emerge in the air, forming the words of the formula.

"We have checked the proof process, there are no errors, and the formula holds."

President Dmitry said in a deep voice.

"Now there's only one question, Reiner, do you think light is really a particle?"
