Seven forty.

Four hours and forty minutes have passed since Zhang Fan cleared the Elite Xuanwu dungeon. During this period, he cleared it three times in a row.

Finally, in the last time, an elite mysterious weapon was spawned.

[Elite Xuanwu Armor (Blue): Increases physical strength by 3 points, increases strength by 1 point, and increases defense by 8 points. Durability 99/100]

"The attributes are so strong. This piece of equipment alone has added 4 attributes..."

Zhang Fan was speechless. If a piece of equipment has 4 more attributes, wouldn't eight pieces of equipment have 32 more attributes?

"According to this equipment calculation, if the eight-piece set is collected, the light attribute can already be improved by one or even two levels..."

After all, after leveling up, each of the four passives adds 5 points to 20 points, plus 10 free attribute points, for a total of only 30 points. And this elite mysterious weapon, with its eight naked attributes alone, may reach 32 points. Compared with

There are two more points to upgrade to a normal level.

This still does not include the effect of the set. If you include the effect of the three-piece set, the five-piece set and the eight-piece set, it is very likely that the battle will be two levels higher!!!

This equipment is so powerful that Zhang Fan is reluctant to sell it now.

"Keep it for now, no one can afford it now anyway..."

After looking at the time, Zhang Fan felt that Liu Yining and the others were about to come up, so he chose to return to the square.

"brush!"

Reappearing in the square, I found that only Xiao Meng and Wang Juting were standing here. None of the expected level 5 experts were anywhere to be seen.

"Lord Barbarian King, you have come out..." Wang Juting greeted quickly.

Zhang Fan hummed and looked back at the stone statue.

[Current number of teams in the copy: 6]

There are six teams, all in the normal difficulty dungeon.

"It's all in there?!"

"Yes, Sister Xiaoyu and the others have all entered the dungeon..."

"snort!"

Xiao Meng on the side was a little dissatisfied, "You are the fake Sister Xiaoyu!!"

Zhang Fan ignored her and asked: "Where are the other teams? Is there any movement?!"

Wang Juting was stunned, shook her head and said: "No, but it seems that every time they finish a dungeon, they will show up and stay for a few minutes, and then go in..."

"Where's the tiger? Has he come up yet?!"

"I came up. I remember her two wet nurses came up first, and then the tigers came up after a while, but they didn't stay for long and then went back..."

It seems that the Tigers and the others also know...

Zhang Fan nodded, opened his address book, found Menghu's name, and sent a message: "Shop No. 1, do you have any ideas?!"

After a while, the news from the Tigers came back, only four words.

"Aim to win!"

Zhang Fan frowned slightly. Since the Tigers and the others had decided to rob the store, why didn't they ask him to download a dungeon?!

Could it be that he was angry because he scolded him?!

Thinking of this, Zhang Fan tentatively said: "Double copy start?"

The message had just been sent, and within two seconds, I received a reply, this time shorter: "No time!"

"..."

Zhang Fan's teeth were aching for a while. He couldn't understand the situation on the tiger's side and was a little worried. "They are not hunting mutant beasts to obtain crystal cores in reality, right?!"

"No, I have to go back and do the math."

Zhang Fan returned to reality and immediately called Yuan Jian, Xu Sulan and others over.

"I'll lend you your brain..."

Zhang Fan told all about the store auction situation in Sky City and the situation of other competitors, and then said: "Tell me, with my current situation, is it possible to get it by night?"

That store?!"

"In an auction, the most important thing is not how much money you have, but how much money the other party has..."

Xu Sulan reacted the fastest and was the first to stand up and speak.

"Currently, your biggest competitor is that tiger..."

"According to your description, there are two suspicious points on the Tiger side..."

"First, he didn't contact you all day yesterday. It wasn't until the evening that he said he wanted to download a copy together..."

"During the day, what was he doing when you were here to take over other schools?! What could be more important than downloading a dungeon with you?! In other words, the benefits would be greater?!"

"Second, this morning, the people from the Tigers only came up with two wet nurses at first, and did not bring anyone else..."

"According to calculations, they shot a total of about 16,280 crystal cores yesterday, of which 10,000 were traded with us, leaving about 6,000 crystal cores..."

"Tiger side, according to you, the two of you went there 7 times in total. You earned 6,000 crystal cores, and he also earned 6,000 crystal cores..."

"Including the remaining income of their two wet nurses, there are at least 12,000 crystal cores left..."

"This crystal core can definitely be upgraded to a wet nurse..."

"But, no, not even the replacement tanks came up. This shows that their crystal cores are used in reality, and the benefits in reality are greater than those in Sky City..."

Xu Sulan paused for a moment and said in a serious voice: "I suspect that in reality, they may be forming a team to clean up the mutant beasts..."

"According to your description of the outside world, other places are much more dangerous than ours, especially mutant beasts, which are countless..."

"Ordinary people can only hide when facing mutant beasts. Even a fifth-level expert can only hide when encountering several mutant beasts of the same level..."

"But the Tigers are different. They are backed by forces with guns, supplemented by hot firepower, and have more than a dozen level four and hundreds of level three superpowers..."

"No, this is the previous quantity..."

At this time, a boy who was standing behind Xu Sulan suddenly came out and said: "According to you, this information was from three days ago. In the past three days, the opponent's strength has been constantly changing.

…”

As the boy was talking, he suddenly took out a blank draft book, took out a pen, and lay on the ground to do the math on the spot.

Xu Sulan smiled slightly and explained: "This is a student from the Department of Mathematics that I discovered. Although there is a gap between him and the geniuses from top universities, he is much better than ordinary people..."

Zhang Fan nodded and found that the boy was still muttering in a low voice. He couldn't help but be curious, squatted down and listened.

"Taking the 14th day of the apocalypse as the end point, there are 1 level 5 left, 11~19 level 4, and 100~199 level 3. Based on this, we can work backwards..."

Zhang Fan was a little confused, turned to look at Xu Sulan, and said: "What is he thinking?!"

Xu Sulan was startled for a moment and said: "It should be simulating the possibility of these people escaping from Lin'an City all the way to the 14th day with so many strong men..."

"Is this calculated by humans?!"

Zhang Fan was stunned. If there was a computer, after establishing the model, it would be possible to input various data and figure it out. But now, the human brain calculates by hand?!

"It shouldn't be as accurate as a computer, but it can calculate the highest and lowest intervals, as well as some things like the most likely probability..."

Zhang Fan always felt a little mysterious, so he leaned down and listened.

"Suppose event A is the number of deaths of D at point X, and B is the number of victims of superpowers, then P(A)=13/556, P(B)..."

After listening for a while, Zhang Fan stood up, pursed his lips, and said, "Let him do the math. Tell me, what should I do to win today's store?!"

Several people looked at each other, and Yuan Jian stood up and said: "According to you, they should all be in the dungeon now..."

"Currently, there are only four companies that have the opportunity to compete for the auction. Anyone with a discerning eye knows that the Tigers and we are the strongest and have the greatest chance of winning, but they are still placing copies..."

"There are two possibilities. One is that they have given up the competition and want to make a lot of money by selling equipment at night. For example, they can sell high-priced equipment to the Tigers and you who are still in a competitive relationship. After all, you two are short of crystals.

They are all determined to win. Whoever they turn to may tip the balance..."

"The second possibility is that they have found some way to break the rules and be able to overtake in corners, beat you and the Tigers, and win the final victory!!!"

Zhang Fan narrowed his eyes and asked: "How can we judge which possibility they are?!"

Yuan Jian pondered for a second and said: "Sell the equipment at a price lower than the market price and test them..."

"If they are determined to compete, they will definitely not let the crystal cores leak out. After all, their own crystal core reserves are not large, and they are unlikely to capitalize on the enemy..."

"If you have no intention of competing and just want to make money, then as long as your price is low enough, they will definitely buy it..."

"I suggest that you use the mysterious weapon as a test..."

Zhang Fan nodded slightly, feeling that what he said made sense, so he opened the communication. When he was about to send a message, Yuan Jian quickly added:

"By the way, you can first try it out with their subordinates, that is, the team members, preferably outside the core and as close to the periphery as possible..."

"good!"

Zhang Fan picked a mage from the Peach Blossom Queen's team and showed him a Xuanwu hat with the attributes of spirit +2, agility +1, and restoring 4 energy points per hour when not in combat.
