When Peter got home, he immediately went into the study. The miscellaneous items in the study are still very crowded, and it is better to say that it is a study, but rather a utility room. Using his flexible body, Peter squeezed his way to the innermost level of the study.

The innermost layer of the study is still the bookshelf, and only here can you see a trace of the study, and the rest of the place, no one believes that this is not a utility room.

Richard. Parker's briefcase had been moved to the innermost level of the study's bookshelf, and now it was locked in a drawer by Peter. Peter unlocked the lock and retrieved the information for the two formulas.

The material was a little old, indeed a few years old, but it was beautifully bound, and Peter flipped it open and went straight to the last page.

On the last page, there are some thoughts and conclusions derived from the formula, and at the end of the conclusion, two lines appear in Peter's eyes:

Richard. By Parker.

Mary. Parker provides consulting and computing services.

"Sure enough, I remember correctly, although I don't remember these two formulas clearly, but I still remember the last signature. Connors was lying to me when he said that he had deduced this formula. ”

Peter took the documents out of the study, and the briefcase remained locked in the study.

"Peter, what treasure did you find?" Aunt Mei said curiously.

"An old-fashioned dollar bill." Peter took out an old hundred-dollar bill, which was also the item in the briefcase, and Peter had expected that Aunt May and Uncle Ben might ask him what he was looking for, so he took out an extra dollar bill.

"Wow, this is an old dollar bill issued after the end of World War II! If it's a Captain America commemorative edition, it's worth a lot! It's a pity that it's only a commemorative version of President Roosevelt, but it's worth $3,000! Aunt Mei took the banknote and looked at it carefully.

"Three thousand dollars?" Peter couldn't believe the number, and in his opinion, wasn't it just an old version of a hundred-dollar bill?

"You take it, it's definitely from your parents." Aunt May read the banknote and returned it to Peter's hand, "This kind of banknote has a high commemorative value, and this banknote is also in good condition, you can keep it as a souvenir." ”

"Aunt Mei~"

……

Peter wanted to give the money to Aunt May or Uncle Ben for safekeeping, but the two of them said that they would not take anything, and in the end Peter had to return to the room with the money.

Putting the money in a book, Peter began to derive the formula from the information.

"Oh, Shift, what's this Fibonacci sequence." Peter turned on the computer and started to look it up, but he didn't expect to run into trouble in the first step of derivation.

"The Fibonacci sequence, starting with the third number of the sequence, each number is equal to the sum of the first two adjacent numbers. An=An-1+An-2。 Peter quickly found information about the Fibonacci sequence.

"Huh? What is the use of this sequence. Peter continued to deduce downwards, and he did not understand the meaning of the sequence.

"Binary operations, alas, although I have seen this method of defining real numbers mapping real numbers when I was self-taught, but it is ...... to use"

All night, Peter struggled with mathematical formulas, and he didn't even go out to fight crime, his favorite crime, as if mathematics was the most vicious criminal, and he had to fight it before he could fight crime.

……

"Peter, your dark circles are getting worse again." Li Ji mocked mercilessly.

"I was too late last night." Peter yawned, but he hadn't slept at all.

"Do the question?" Li Ji didn't believe it, Li Ji felt that Peter must have gone there last night to punish evil and promote good.

"yes...... My hair is falling out. Peter complained, but even then, he had been progressing all night with the derivation of the formula, which was aided by a ready-made demonstration of the derivation process.

"By the way, Peter, I heard Loki say that someone was looking for you yesterday?" Li Ji said quietly.

"Well, yes, one of my elders." Peter didn't say who Connors was, and he was still a little skeptical, and he didn't want to drag Lee into such a strange incident. What he didn't know, though, was that if he said Connors' name, Li Ji would definitely know Connors better than he did.

"Thor, what do you see that man looks like?" Loki pointed at Peter and whispered.

"Like the Turks of the Nibelungen." Thor said.

"Hahaha, it's really like, the Turks like to paint black paint around their eye sockets, just like he looks like now." Loki chuckled.

"Hahaha......" Thor laughed along.

Li Ji glared back at the two of them, Thor was still smirking, but Loki didn't know when he had stopped smiling, looking like a good boy who was serious about studying.

When the first class ended, Li Ji looked at the empty seat next to Peter, and said to himself a little strangely, "What's the matter?" Why didn't Harry come again? ”
