In the afternoon, the sun fell on the desk through the shutters. A squirrel ran and jumped happily on the hundred year old sunken bookshelf. Under his feet were the secret scriptures of knowledge and the Bibles in various fields.

The squirrel's jump didn't stop until it was on the wide desk. He raised the tip of his nose and sniffed, his big eyes turned, and then began to lick with a finger smeared with peanut butter.

The owner of that finger was an old man in a suit. In this leisurely afternoon, the old man rarely showed a lazy, half leaning back on the chair, full of academic monocular lenses, and his wise eyes looked at the boy opposite the long table.

"Compared with the clear and fresh spring tea, the slightly bitter summer tea and the strong aroma winter tea, in fact, I prefer autumn tea. The tea fragrance is flat, pure and long. When drinking tea, people can always recall some past events."

The old man raised his hand and asked, "my tea art should not have been pulled down in the new West Lake Longjing."

Lu Chen respectfully raised his glass and drank it in one mouthful. The tea fragrance was peaceful and neutral, with a faint aftertaste. It was really good tea. In fact, he knew that there were complicated etiquette in using tea.

He knew that one of his comrades in arms was a girl who was good at it, but he always drank the tea made by the other party.

I'm so thirsty after the war. Do I still play these fancy games with you?

The headmaster obviously doesn't seem to care about these people. He just seems to want to talk.

The day after he returned to the college, he was informed that he had the opportunity of the president's afternoon tea.

"It's delicious."

Lu Chen commented bluntly.

"Just like it."

Ange wiped her fingers, patted the little squirrel on the head and motioned it to play.

"The performance of this mission is very good, worthy of your S-class name. I believe there will be no doubt in the college, and so will lion heart."

Angre picked up the tea set, got up, went to Lu Chen and added tea to him. For a moment in Lu Chen's eyes, the stool the headmaster had previously sat next to him.

"Is this time zero?"

Lu Chen was curious. Just now, even with his dynamic vision, he only saw a slightly blurred shadow, which was a strange feeling. It didn't seem that the old man became faster, but that he became slower.

The moving of the chair is silent, just like the moving process is pinched off from the time axis. This is the difference between the pure acceleration essence of time zero and the moment.

If Lu Chen does this, he can also complete this move in 0.1 second, but it will bring strong wind and even break the floor when his feet force.

The headmaster did it with such understatement. He just moved a chair in his own time.

"The desk is too long. It's really easy to distance people."

Angre sat down with a smile. "Time zero is really magical, but the moment is also a great speech. Although the sequence is below time zero, it has the potential to not lose to time zero, at least for you."

Lu Chen sat up straight, like a good student who listened carefully.

"How many steps can you climb now?"

Ange asked casually.

"Fourth order, sixteen times acceleration."

Lu Chen replied that this was the result of his thinking in advance.

At that time, in order to get to Hongshan Park in time, the distance of 10 kilometers only took 57 seconds. According to his physical test results, it seems to be a little more than eight times, but in fact, it can't be counted like that, because the city is not a runway.

Considering various obstacles and temporary detours, his actual speed is about 13-14 times.

Since he decided to disguise the instant spirit, Lu Chen has also done a lot of investigations and consulted a lot of materials at the lion heart club. Now he knows a lot about the spirit.

The so-called speed doubling of the climbing level is not an absolute value. It is said that it has increased 16 times, but in the actual environment, it can't reach that speed at all.

Because in the real world, the high-speed movement of the body will also be affected by factors such as air resistance and ground friction coefficient. These effects become more obvious with the higher the order of the moment.

The shrinkage below the sixth level in an instant is not serious. According to the inference, if you climb to the Ninth level in an instant, you can't reach 512 times the amazing speed at all. It's good to actually hold up 200 times. Moreover, it also requires the user's physical function to be extremely powerful. Otherwise, if you keep that speed for a few seconds, the body will be unable to bear it first.

External friction and high heat will also burn people's skin, just like meteorites falling into the earth and satellites returning to the earth.

Therefore, it is not unreasonable for time to be zero in the moment. The former is like a king who tampers with the rules, and the latter is a reckless man who relies on brute force.

"Yanling will climb to this level soon after awakening. It seems that you are really talented. As I said, this Yanling is very suitable for you, because your initial speed is very fast and you will be faster when waving a sword."

Angre tasted a Longjing and looked at Lu Chen's eyes full of appreciation.

"I heard that Viscount Charlotte of silver wing, the most famous instant user in the history of the secret party, used a revolver. According to your meaning, it seems to encourage me to use a sword?"

Lu Chen was puzzled. Although he really liked to use cold weapons, he thought the headmaster would suggest him to use hot weapons.

"Viscount Charlotte is one of my mentors. There is no doubt about his strength."

Angre's eyes floated with the squirrel jumping on the bookshelf, "but even so, I have to admit that bullets were too weak in front of the king level enemy. If he had an alchemical sword in his hand..."

Angre shook his head and smiled, "I'm off the subject. People always love memories when they are old."

Lu Chen didn't mind. He just sat upright and waited for the headmaster's words.

"When the body strength is enough to bear the rising speed, it is obvious that the speed of cold weapons can far exceed that of bullets, and the different quality also determines the great difference of kinetic energy. Bullets can't break the hard keel, but alchemy knives with great kinetic energy can. In my opinion, you don't lack strength, and using cold weapons is the best choice."

Angre's simple comment, his hand shook, a pad appeared in his hand, clicked twice and put it on the table.

Lu Chen noticed that there was a picture on it. He was familiar with the person in the picture. It was the rickety man he killed when he first came to the world.

Lu Chen was silent. At first, he didn't know what he would face after the task was completed. He shouldn't kill the rickets man in that way, which indirectly exposed his abnormal strength. For this reason, he worried for a long time, but the college didn't ask him about it. Today, it seems that the college didn't know or care, but the old man in front of him suppressed it.

"Don't worry, no one knows about it except me and your mentor, and all the commissioners related to that task have signed a confidentiality agreement."

Angre took a sip of hot tea and raised his hand to let Lu Chen relax.
