In the process of taking a floating boat, Lena quickly noticed that this dock is not only for ordinary people to take a floating boat, but also for high-level mages to take off, or some mechanical mages to use their own flying props.

Lena doesn't know how to fly magic, and he doesn't have his own aircraft. He can only take a slow floating boat.

He saw that the world already had the rudiment of airplanes, but most of these strange shaped airplanes still imitate birds' flapping wings and fly very funny. What is more popular is the small single person floating boat, which can only ride one person. The shape looks like a motorcycle without wheels. This kind of airplanes can keep floating even on land, Reiner secretly remembers Under the brand, ready to buy one to study.

It took about ten minutes for the floating boat to arrive at the island where the mercury balance is located. According to Leiner's chat on the floating boat, except the main island, the rest of the rainbow tower airspace is occupied by legendary mages and powerful academic organizations. The island where the mercury balance is located is called the fourth district.

The fourth district is the only island with a huge lake besides the main island, so it is also a tourist attraction. There are many magical creatures in the forest around it, which attract the mages who study these things.

At the same time, Lena also learned that most of the mages who took the floating boat together were residents living on the island, and some of them were tourists who came to the rainbow tower these days and prepared to visit every place. The destinations like Lena were mercury balance headquarters, but none of them.

From the floating boat, Lena took the loop around the island to the headquarters of mercury balance.

This manor is located by the lake, and its architectural style is closer to that of the ancient magic empire. It is not surprising to think that this island was once the capital of the ancient magic empire.

"I have an appointment with Mr. Eagles field."

At the gate of the manor, Lena presented his identification to the man on duty.

The person sitting in the duty room took the document from Lena and carefully confirmed it before returning it to Lena.

"I didn't expect to see you again in less than a year. I'm still an unknown four ring mage, and you've become a celebrity who can talk about magic with senior mages."

The mage on duty said with a wry smile, making Lena confused and looking at each other's face.

This is a featureless face with a little baby fat. The man looks only in his thirties. He is young at the level of the Fourth Ring Road.

After searching in his memory for a long time, Lena still didn't remember which one he was.

"Well, I'm sorry, could you ask me where we met before?"

Asked Lena, adding to the bitterness of the smile.

"Ah, well, after all, I'm just a handyman. You shouldn't remember me."

The man shrugged and continued.

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

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

"I'm sorry."

"It doesn't matter. Please come in. Mr. field's office is on the third floor, the second one on the left. If you can't remember, you can ask the receptionist at the headquarters."

Anton didn't worry about it too much. With a wave of his hand, the alchemists stationed at the door made way for Lena and Claire to pass.

This episode made Lena feel a little bit. He has made continuous progress for special reasons, but there are still more people in the world who have always stood still.

So far, Claire has no sign of advancement. Maybe she is really not suitable for learning magic, but because she was adopted by crescent college since she was a child, she will move towards the road of mage.

Lena sometimes has to think about a problem. According to the current situation, he may be promoted to a higher level within a few years, and at least have a life span of more than 300 years. However, Claire can only die a hundred years later, just like ordinary people.

He has not experienced the life of an elder, so naturally he has no corresponding experience. Lena does not know whether he should make some decisions.

There is no bleak feeling of autumn in the manor. Lena and Claire walk into the mansion. There is no one in the big room, but it seems very busy. They go up the stairs and find Mr. field's office.

After knocking on the door, Lena got a response. He pushed the door in, but the first thing he saw was not Lord field.

"Lena, long time no see."

Frederick Demetri, the president of the mercury balance, is sitting in a chair to greet Lena.

"President Dmitri."

Then, on the other side, Lord field, the owner of the office, spoke.

"A good-looking gentleman deserves a beautiful lady. It seems that you know that very well, Lena."He joked that it was not the first time Mr. field had seen Claire, but he was keenly aware that the relationship between Lena and Claire seemed to be closer.

Clare became a little shy because of Lord field's words, half hiding behind Lena and holding the corner of his coat.

"I'm laughing, sir."

"Don't be joking, Lena. Is your companion a wizard? Can she accept your theories?"

Asked Lord field, adding immediately.

"Because in other research institutes, there was a middle-level mage who accidentally saw your paper and almost had a cognitive breakdown, so we are worried about a similar situation."

"Don't worry, Mr. field. If anyone in the world can completely trust me and understand me, it must be Claire."

Lainer replied that Clare knew all his discoveries, and after long-term following lainer, Clare had a strong acceptance of new things, at least until wave particle duality.

When she heard what Lena said, Claire felt shy and happy. She always felt that she didn't give Lena a a lot of help like other students. She felt that she might be a drag on Lena. But now it seems that Lena still trusts her.

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

President Dmitri got up, waved, and from his desk came a parchment, a copy of Lena's paper.

At the same time, a trail of light emerged in the air, forming the words of the formula.

"We have checked the proof process, there is no error, the formula is true."

Said President Demetri in a deep voice.

"Now there's only one question, Lena. Do you think light is really a particle?"
