Research literature: "Guidelines for solving difficult problems of the year - Issue 1"

Original price: 588 contribution points.

Release method: Release separately.

Because each problem requires a large amount of calculation formulas and data, it was finally decided to be released separately, and each problem was used as a separate document.

Re-rated according to the difficulty of the problem!

in--

The easiest problem to solve is rating r, a total of 60. The more difficult problem, rating sr, a total of thirty problems, a total of thirty problems, a total of rating sr!

The purchase method is simpler. You can buy a "r-level problem package" with just a little contribution value, and you can get a random document in it!

It may be R-level, it may be sr, or it may be ssr!

Is it cheap?

Of course it's cheap!

The original price is 588, okay?!

Each of these problems is a difficult problem. Chen Feng has developed it and I don’t know how much the price he has paid. Although 588 is expensive, it is definitely worth it! What’s more, this is just the original price. The current price is that you only need 1 contribution point to get one immediately!

Is it cost-effective?

Absolutely cost-effective!

Many people have even prepared hundreds of contribution points to purchase.

"I'll try it."

Someone tried to buy one.

brush!

Congratulations on obtaining a copy of the sr problem document, the problem description is as follows...

"Hahaha, I got the high-level literature in one go."

The man was excited.

"So good luck?"

The others also went to buy with great interest.

Everyone was discussing excitedly.

People are very excited from the first purchase, because they only need one contribution point to get answers to this rare and rare question!

So happy!

You must know.

The normal price in the institute needs at least 10 o'clock?! No matter how bad the problem is, you will dare to sell it out as long as it is solved!

one!

two!

Three!

...

Someone bought ten at once, which was so cool!

even--

Some people began to complain about Lan Jingling.

"Hey, Senior Lan's last document to solve the problem requires 30 contribution points! Yes, yes, although the problem has been solved, but..."

There is no harm without comparison.

Compared with Chen Feng’s 1 contribution value, Lan Jingling is simply too scammed!

"Maybe, this is Chen Feng's way?"

"Although I was unable to get an honorary producer, I finally got a reputation."

"Um……"

"How can I compare it with Lan Jingling so cheap? Forget it, I will buy a few more copies to support Chen Feng. Anyway, it's just a few contribution points."

"So too, the problem I need seems to be at the ssr level."

brush!

brush!

Countless people began to draw.

Star City.

Global Producers Branch.

All the producers entered the crazy draw package at this moment, and at this time, they didn't even realize the problem...

And at this time.

Star City.

"Chen Feng?"

Harry looked at Chen Feng excitedly.

"Haha, Harripo...oh, Miss Harry."

Chen Feng looked at the mountain shaking on her chest helplessly. Did this little girl not feel such huge pressure every time she ran away?

"I bought your literature."

Harry was excited, "Hehe, many people say you are kind and cute. Although you haven't won the honorary producer, everyone will support you!"

“Huh?”

"You're going out?"

Harry looked at Chen Feng's attitude.

"Well, I'm afraid of being beaten... Oh, no, something is wrong."

Chen Feng coughed.

"Oh, that won't delay you anymore, come on."

Harry encouraged.

"Uh-huh."

Chen Feng retreated quickly.

only.

As soon as I walked to the door, I saw another person - Lan Xing!

"It's this guy!"

Chen Feng's mind was beating wildly.

But then I thought about the fact that this is Xingcheng, so I was no longer afraid and frowned slightly: "Why are you here?"

only.

What surprised him was that Lan Xing actually came to show his goodwill.

"That..."

"I blamed you wrongly."

Lan Xing scratched his head honestly.

"oh?"

Chen Feng was unexpected.

"They said you're a good person."

Lan Xing thought for a while, "I think I might have misunderstood you before. My sister said that honorary producers are crucial. To become honorary producers, you can also gain real power. Enter the management of the Gene Production Association and become a real part. You will never give up!"

"But I think my sister is wrong!"

Lan Xing said righteously, "Today your document is on sale, I heard many people praise you, saying that my sister is too cheating and selling too expensively. I think my sister may be blinded by interests..."

Chen Feng: "..."

"I hope you persuade my sister."

Lan Xing said seriously, "There is nothing important for honorary producers. It is really important for everyone to say that good things are really important."

Chen Feng: "..."

He looked at Lan Xing with a look of looking at a fool.
