Looking at the complicated topic on the nine-square grid, Fang Yu rolled his eyes, this topic will not be seen by no one, since it is stored in this collection hall, it means that the entire Cambridge people know such a thing.

What's more, this is Cambridge, a world-class university, a place rich in talent, and these topics don't necessarily stump the students or teachers in the college.

He picked up the flashlight and looked at the problem on the nine-square grid carefully, and then found the problem, it turned out that the nine grids were not some conventional math problems, but a piece of text.

The nine compartments contain the great deeds of Newton's life, and he was admitted to Trinity College, Cambridge University in 1661. In the first half of 1664 he began to work on new mechanics. In 1665, Newton received a bachelor's degree. In the same year, Newton returned to his hometown to escape the plague, and these two years were the peak of his inventions. He successively founded the binomial theorem, the decomposition of light, the flow number method, and also established the basic ideas of the first and second laws and the law of gravitation. In 1668, at the age of 26, Newton returned to Cambridge and was chosen to succeed Barrow as professor of mathematics. In the same year, he collaborated with Barrow on the Lecture Notes on Optics and Geometry. In 1675, the famous "Newton's ring" experiment was performed. In 1684, with the enthusiastic persuasion and support of his close friend Halley, Newton published his magnum opus, The Mathematical Principles of Natural Philosophy, which proclaimed the formation of Newtonian mechanics and its influence spread throughout all fields of natural science. He was knighted in 1705 and never married.

In addition to the invention of calculus, the law of gravitation, and the three laws of motion, and the creation of a complete mechanical system, Newton also discovered the spectrum of sunlight and invented the reflecting telescope. Physics for more than a century had its first great synthesis with Newton. But he humbly said, "If I see farther than others, it's because I'm standing on the shoulders of giants."

These achievements fill eight of the squares, leaving only the last blank one, controlled by three gears that rotate 26 letters and 10 numbers from 0 to 9.

Fang Yu carefully turned one of the gears, and the ticking sound meant that this dark grid could be used normally.

"Just three? What is that? This product finished the invention before the age of 26, and spent the rest of the time worshipping God, and already wanted to make gold out of brass, no, the English word for gold is gold, and it is also four letters. Fang Yu toggled the gear dials.

Then he moved his mind, and then he flicked the letters one by one, and after a while, he spelled out "God", thinking that Newton should also believe in God.

But it's a pity that the dark check pattern doesn't move at all, and it doesn't open directly as expected.

"Fang Yu, hurry up, okay, it's been 20 minutes." Zhao Bin tiptoed over.

"What's the hurry, I can't eat hot tofu in a hurry, I'm solving the problem."

As soon as he heard that he had to solve the problem, Zhao Bin smacked his lips dissatisfiedly,

"Don't you have a potion, there are still problems in the world that you can't solve, oh, what Einstein Newton's, you just buy their potion."

"Damn, it's not a math problem or a physics problem, it's useless to buy it, you hurry up and go to the sentry, don't be found out later." Fang Yu drove Zhao Bin back to the staircase again.

He sat down with his ass and tried to calm himself,

"Newton, the source of wisdom, hiss, if you count it like this, I myself am the host of 007, Ramses II is 001, and Caesar is 003, then Newton's birth date is more than 1000 years later than Caesar, how to calculate it should be after 004."

Thinking of this, Fang Yu carefully dialed the turntable to 004 again, but there was still no movement.

"Isn't it 004? Could it be 005? ”

He was a little discouraged, and casually pulled the last digit back, but unexpectedly, the dark grid made a squeaking sound, and there was a sound of gears turning inside.

"Damn, there's a play!" He jumped to his feet in shock.

The sound of gears inside the dark grid turned a few times, and only to hear a "click" that all sounds stopped.

Fang Yu tried to pull the door of the dark grid, and sure enough, it was opened all of a sudden!

He pressed his excitement and shone it with a flashlight, which was not very large, and there was a large wooden box stored inside, which did not seem to be locked, and it was covered with dust, and there were even some insect moths on the outside of the box, which was obviously some years old.

"Gan, I found it, Zhao Bin, pay attention, observe at any time." He quickly poked his head out and shouted in a low voice in the direction of Zhao Bin.

"Understood, you got yours." Zhao Bin shook the flashlight, meaning that he had received it.

Fang Yu carefully picked up the wooden box, and he could feel it from the weight in his hand, the contents were quite heavy.

There was no key on the box, only a buckle made of gold was used, Fang Yu tried to calm himself, tried not to tremble and slowly lifted the buckle, and then raised the flashlight to shine it.

There were many things stored in the box, a delicate golden apple, a silver coin, and a few pieces of burnt and yellowed paper, on which some words were written in quills, and it was not clear for the time being.

"Oh, it's real money?" Fang Yu checked the golden apple in his hand, it seemed to weigh twenty or thirty grams, and the silver coin was slightly lighter.

He put the golden apple and silver coin in his pocket, and carefully picked up the paper at the bottom of the box, and studied it carefully by the light of the flashlight.

"I, Isaac Newton, the knight of the Kingdom of Britain in Europa, have a system that is unique in the whole world, God willing, I have received a gift from the Lord, the golden apple is far more important than the fruit of that apple tree, but I am too old to look for the traces left by the previous host, please read this letter, inherit my will, the Lord will bless us......"

When reading this, Zhao Bin hurriedly jumped in with a sliding step,

"Let's go, the security guard is here again, it's a patrol every hour, it's really troublesome!"

Fang Yu was shocked, and hurriedly stuffed the papers back into the box, carefully closing the secret compartment, and not forgetting to scramble the number of the mechanism opened before.

The two of them took advantage of the fact that the security had not yet come up, so they hurriedly went down to the 3rd floor, got into one of the archive rooms, and carefully hid it, but it was full of dust, and Fang Yu covered his nose tightly, enduring not letting himself sneeze.

The security guard walked towards the 4th floor in the same way, and it was another 15 minutes before humming a little song, as for the facilities on the 3rd floor, he barely checked it carefully, just took a random photo with a flashlight, and went downstairs again.

"Ahh Fang Yu couldn't help but sneeze twice, fortunately, the security had already gone away, the two of them returned to the second floor, climbed out of the window, and sneaked for a long way by the moonlight, before returning to the vicinity of King's College, their car was parked outside the wall.
