"What are we going to do next?" Looking at the basement in front of him, Hu Yuan asked curiously.

"Simple, go all the way through the customs and find the order hidden in this secret room!" My cousin said.

"Cousin, is this order important to you? You've worked so hard to get it! Ling Hu Yuan asked curiously.

"Of course it's important, cousin has a golden defense tower, waiting for it to be activated!" The cousin sighed and said, "Your sister, I worked hard to get a golden defense tower blueprint, but it turned out that I had to unlock this Laoshzi's Moment Order, which is a dead person!" ”

"Then cousin, you don't have to lose, generally speaking, defense tower blueprints like this that require special props to unlock are all old defense towers!" Ling Hu Yuan's eyes lit up.

Ling Huyuan is right, generally speaking, as long as the drawings are obtained, and the prerequisite skill conditions are met, or the restrictions of the sect and profession, they can be built.

But there are some very special drawings, they also need some special items to unlock and build, and these special items are basically strange things, and players often have to spend a lot of effort in order to collect these items.

However, there must be a gain, and the hard work consumed by players is not unreasonable, and after statistics, players have found that those defense towers that require special props to build are often much stronger than defense towers of the same level and color.

That's why this cousin is so obsessed with this copy, you must know that what she has in her hands is the golden defense tower blueprint, if it is this kind of blueprint that requires special props to unlock, then this defense tower is infinitely close to the red epic level defense tower, which is definitely worth any price for a player!

"This copy is a bit similar to a secret room game, each room is a secret room, and you have to go through one secret room after another to finally reach the end of storing the moment order!" The cousin explained.

"In that case, it's a puzzle game, and we need to find the secret to open the secret room here!" Ling Hu Yuan's expression was a little uncomfortable, what he hated the most was puzzle games.

"No, this secret room doesn't need you to solve the puzzle, the way to open the secret room is on the surface, as long as you can complete his task, you can open this secret room and enter the next level!" The cousin shook her head, and then continued, "For example, in this first secret room, its test is placed on the middle table, it is a math problem, as long as you solve this math problem, you can open the door of this secret room!" ”

After the cousin finished speaking, the other two looked into the center of the room, and sure enough, there was a desk the size of a desk, and a knife was placed there.

"The math problem is engraved on the table, and then we need to carve the correct answer on the table with a knife!" My cousin said proudly, "I've been to this room many times, but this math problem has never changed, and I can carve out the answer with my eyes closed!" ”

As my cousin spoke, she walked to the side of the table, and when she lifted the dagger and was about to engrave the answer, her whole body suddenly froze, and then she began to tremble.

"What's wrong with my cousin? Any questions? Ling Hu Yuan noticed that something was wrong, and immediately asked nervously.

"Title...... Topic ......" My cousin pointed to the question on the table and said in a trembling tone, "The topic has changed...... The topic here has changed, it's not the previous one!! ”

"How so? Didn't you say that you've been here a dozen times before, and the topic here has never changed? Ling Hu Yuan said anxiously.

"Yes, I don't know, I don't know why I became like this, I haven't changed before......" The cousin's expression became very ugly.

"It's probably because of the old man!" Zhang Qiuhan on the side said slowly, "You used to walk for an hour, and then you came in after the passage automatically opened the exit." The old man is different, the old man directly blasted the door open, so it is estimated that the title inside this secret room has been changed! ”

"What!" The cousin's face turned pale suddenly, and then pointed to Zhang Qiuhan's nose and said, "It's all your fault, walk well, what if you walk for an hour?" Now I can't even solve the first secret room, the problems here are all college math level questions, I spent 10,000 yuan to get a university teacher to help me make the correct answer! ”

"Where can I find a university teacher to help me with the topic, it's all you, and I've wasted a day today!"

My cousin's mentality seems to have really collapsed.

"Isn't it just a difficult topic in college? Don't worry, cousin, you forgot that my university is a mathematics department, and I helped you solve these problems! Ling Huyuan hurriedly came out to play a round road, and then looked at the topic with confidence, "Cousin, you don't know that my math ability is not good, and the school has a math scholarship for which year!" ”

"Oh!" Hearing Ling Huyuan say this, my cousin reacted, and a happy expression suddenly appeared on her face.

That's right, my younger brother is a top student in the mathematics department, and he will definitely be able to solve this problem!

"Let ()||||fxx is a functional on the real Hilbert space H, which proves that when 0x,()fx is a Gateaux differential ...... along the h direction at the point x, Hu Yuan reads the problem, and then the whole person's expression becomes almost crying.

"Cousin, I'm sorry, this is not a college student-level question, this is a doctorate-level question, I can't answer it......"

"What! University Ph.D. Level Math Problems!! My cousin's eyes widened, and she seemed to be about to despair, "Are you mistaken?" What are you kidding, it's just a game, how can you design a doctorate-level topic?.

"I'm not kidding, this is indeed a doctorate-level topic......" Ling Huyuan had a tragic expression on his face.

"You...... Forget it, let's go back! The cousin sighed deeply and calmed herself down as quickly as she could.

Since this is already the case, let's go back first, it's a big deal to waste a day, so what? It's not a matter of life and death!

Thinking of this, my cousin suddenly felt a lot more comfortable, but thinking of the guy who had wasted a lot of time, my cousin was angry again, and her eyes began to look for the culprit.

And so, our cousin saw that the damned fellow was lying on the table with the dagger in his hand, and seemed to be carving something into the board.

"This guy actually thinks that he can solve the math problems of doctoral students!" My cousin's face was full of mockery.
