Tae-sa was surprised, and then her expression began to become strange, and she kept looking Tianxian up and down, "You know what I'm doing?"

"It should be. "Keep smiling.

"You ......" hesitated for a moment, Taisa's expression was even more strange than just now, "You can calculate?"

Normally, Tian Xian would not want to pay attention to such casual contempt, but now it is necessary to stall for time here.

Showing a helpless look, Tian Xian looked upward, as if he was interested in the wind chimes in front of the gothic window in the room, and replied indifferently: "I understand a little bit." ”

Tai Sa was not annoyed by Tian Xian's not very respectful expression, she thought for a while, but asked with some doubts, "You say...... Is it in a place three kilometers away?"

"Hmm. Tianxian's eyes were still looking upward, and he nodded casually.

"Why!?" Taisha's gaze pressed straight into the sky.

Tian Xian lowered his gaze at this time, but he didn't look at Taisha, but fell to the floor, stretched out his finger and pointed to the ground and asked, "If you want to know, then I need to take a few steps and go to your table to show you once." ”

Without hesitation, Tae-sa reflexively went to her messy table and grabbed a pen and paper, but she quickly hesitated and fell back into thought.

A look of struggle flashed in her eyes for a long time, but she still put down the pen and paper, "Okay, you can come in, but you can only go here!"

Tianxian couldn't help but smile secretly, sure enough, this Taisha's temperament is still good, it seems that she wants to throw the pen and paper over and let her calculate it at the door, but apparently immediately realized that this is too arrogant and rude, so now please go in by yourself.

"Thank you. With happy steps, Tian Xian came to the big table of Thai yarn next to the hall.

When I got closer, I found that around this large table was actually a complete private world, with many personal decorations on the table. Some of the utensils that may have been related to eating and drinking, there was even a small bed behind the table against the wall, and now there were some elven sarcasts scattered on it.

Around it, there are still a lot of books and papers scattered, and there are also some miscellaneous items, which seems to be messy around. It's hard to imagine that this is a place that belongs to a certain elf who pursues perfection, thinking of the current state and dress of Taisha, Tianxian estimates that she has been having a headache for a long time, maybe she just stayed up all night yesterday, so she is a little grumpy today.

"Human, take care of your eyes!" Taisa noticed that Tianxian's eyes were rolling, and he immediately began to regret allowing humans to enter his house.

"Oh, I'm sorry! I've entered the elven city for the first time, and I've never seen an elven house. It's inevitable to be curious, so don't be surprised. Tian Xian smiled apologetically and sat down at the table.

I took a piece of paper casually, and then carefully picked up the carved ink pen as light as a feather - I couldn't help but sigh that this pen could buy a house in the human world just because of its exquisiteness.

Casually tapped a few large pieces of paper on the wall opposite the table, Tian Xian lowered his head and wrote: "Now to build a checkpoint outside the royal city, the location of the checkpoint must be appropriate and very accurate. Too close to the royal city loses the significance of a sentry post, and if it is too far away, it will be isolated in the forest. Not only will it be besieged by monsters, but it will also be difficult to supply, which is equivalent to a sheep in the mouth of a tiger. So now list all the conditions, the time of supply transportation, the distance from the royal city, the time of early warning, the time of rescue, and the speed of support of the elves......

As he spoke, he quickly laid out a long equation on the paper.

"It's great that there is a large lake and neat forest around the Elven Royal City, so that many conditions are almost fixed, only the distance from the outpost to the Royal City is unknown. Set it to X, do you know X? It's an unknown! So there's only one unknown, a one-dimensional equation, and you can see that the result is three kilometers!"

"Then let's take a look at the map. ”

Tian Xian pushed the file on the table away and flipped out the map below. "Three kilometers, that's the location. ”

Drawing a circle on the map with that exquisite ink pen, and knocking twice on the five points on the map, Tian Xian continued: "Considering the situation of mutual warning and support of the checkpoints, the distance can be slightly extrapolated, that is, the outer edge of a large forest, and the checkpoints are built on the edge of the forest, with a wide view of the outside world, and the distance is just right, and these places are close to the water source......"

Taisha listened carefully to every word in her ears, and she was extremely shocked.

Where should the sentry be established, this question has been bothering her for a long time, as a guard officer, she must come up with this plan as soon as possible, because the forest has been very uneven recently, but since ancient times, there is no such precedent for elves, no one knows where to set up a sentry post, and then only let a dozen or even three or five elves stay there alone, this position must be grasped very well, otherwise the elves in those sentry posts will become sacrifices in the forest, and they will become sinners!"

And this human being, who actually said the Tao, explained the previous mess of problems clearly......

"Knock Knock ......"

Just as the day's gossip was rising, and Taesa was surprised to hear it, there was a knock on the door outside.

Tian Xian glanced out and asked Tai Sha with his eyes.

But Taisha, who was thinking about the problem in her head, didn't react at this time, and subconsciously said, "Come in." ”

As soon as she spoke, she realized that she had made a mistake that she might not have been able to make amend, but it was too late to stop it first.

Then, a handsome and tall male elf pushed the door and walked in, he had an elegant smile on his face, calmly, and was about to say hello to Taisa, but suddenly saw Tian Xian sitting at the table, and was completely stunned.

Sometimes, people are prone to make mistakes over and over again, and this situation is completely common to elves.

Taisha almost popped out two steps at once, blocking in front of Tian Xian, and she asked in an extremely serious and annoyed voice, "Is there something wrong?"

The male elf was only stunned just now, and now the look on his face can only be described as shock, "The elf king wants to know when the guard plan will ...... to be able to make it. He stammered.

"Soon!"

Tai Sha's eyebrows trembled slightly, she wanted to use her body to block Tianxian, but she immediately realized that it was useless, she was slender and slender. And with the sword still on his back, the heavy blunt sword was simply one of the most discordant objects in this delicate elven dwelling, and it was incomparably piercing......

The male elf opened his mouth and looked at Tian Xian behind Taisa in disbelief, and Taesha was furious in his heart, and he blocked his vision again. "If there's nothing else to do, you can go!"

"Yes...... Be. ”

Perhaps in the consciousness of the elf, it is absolutely impossible for a human being, a monkey, to appear here, the male elf was a little dazed, nodded, and turned around and retreated with a somewhat dull expression.

Tian Xian looked at the door, and then looked around, making a thief's heart like a thief, and couldn't help laughing. "Lord Guard, is it so unforgivable for humans to appear in your house?"

It's okay not to say it, but when I talk about it, I feel ashamed, remorseful, and annoyed...... A series of expressions continued to change on Taesa's face.

Tian Xian was very afraid that Taisha would be as terrible as Luna, so he hurriedly held up the map and his own equation, "But you just need to give this to the Elf King, and everything will be completely solved!"

There is actually a human hidden in the house of the guard officer Taesha!

Taisa's brain is a little dizzy, tomorrow. Or today, the news will spread throughout the Elven King City. I'm going to soon become a topic of conversation for hundreds of years!

"You ......"

Although the problem that had been bothering him was solved, the new trouble was not easier than the previous one, and Taesa had the urge to kill the human in front of her.

"Your Excellency the Guard!" Tian Xian held up the map and the equation again, "You asked me to come in, and I just calculated the results and did nothing against you. And ......"

Looking at Taisha's face, Tian Xian weighed the words, "And the presence of humans here, is it really that serious?" I have asked for the second time, can you ...... Can you explain a little bit?"

Taisha knew that what Tianxian said was right. He didn't do anything bad to himself, but did himself a great favor.

Slowly swallowing the bitterness of anger back into her stomach, Tai Sa snorted and stepped forward to take the map and paper from Tian Xian's hand, "You won't understand, and I don't want to explain." ”

Is there something going on?

Tianxian looked at Taisha's appearance, and her eyes seemed to be somewhat helpless.

Placing the paper and map with the equation on the table, Taisa looked at the equation carefully before quickly giving up studying the map.

She tapped her fingers on the marked locations on the map, whispering something in her mouth, as if comparing and verifying, and soon, she was surprised again.

Tian Xian sat on the sidelines, didn't speak, just looked at Taisha.

Now Tianxian knows very well that Taisha knows whether the result he has obtained is correct, and maybe all kinds of chaotic conditions will affect it when there is no result, but if there is a correct result, then it is much easier to extrapolate the known conditions.

Sure enough, Taisha brought the equation to Tianxian before the thought of Tianxian disappeared, "What is this?

Tian Xian is very happy now, especially after being scanned with a gaze like "Wild boars also go up trees?".

But the sky is so idle that I can't show it, let alone make it loud.

One yuan equation, Tian Xian didn't know that this was the knowledge that students in the first few grades in China would learn, because Tian Xian didn't go to school, but there was once an illegal university professor who molested a female student who was beaten on the head and broke her blood to seek medical treatment, and Tian Xian learned some basic arithmetic from him.

The reason is that Tian Xian wants to tease the daughter of the grocery store owner opposite, so Tian Xian specially learns the knowledge that the little girl is learning to show off his knowledge.

Looking at the surprised Tai Sa, Tian Xian understood at this moment that she was actually about the same level as the grocery store owner's daughter......

Of course, there is no mathematics in this world, and there are no equations......

This is simply spreading the wisdom of human beings! Tian Xian suddenly thought of this, and instantly felt that he was great, Tian Xian didn't know that even his expression became divine at this moment.

"Yes, this is human wisdom. ”

Taisha was surprised, because humans should be savage monkeys!

"You know elven script?" Taisa suddenly realized a fact that surprised her even more - all the writing on this table was written in orthodox elven script, how could a human, and a teenager only know elven script.

Tianxian pursed his lips, thinking to himself what is so difficult about the elven text, those ancient divine texts are called difficult to speak, haven't they been learned a lot by themselves?

Although she felt Tianxian's disdainful gaze, Taisha was not dissatisfied this time, because she suddenly realized that the human boy in front of her was much better than she imagined, and he even guessed that five checkpoints would be established outside the city, and made reasonable inferences to directly solve all the problems.

These questions have been bothering him for three months, and the young man has been talking about the answers from the time he enters the door to the time he speaks, perhaps...... Not for three minutes.

Is this really human intelligence?

Absolutely impossible! The barbarism and rudeness of human beings have been witnessed by history! They are like uncivilized beasts, and wisdom is a complete luxury for them.

Tai Sha suddenly lifted, and the young man in front of him became more and more incredible, it was simply ...... The moon god is on top, how can this be a human! If it is an elf disguised as a human, it is reasonable!

"What's your name?" asked Taisha in a soft tone.

Tian Xian smiled slightly, and finally agreed to ask the name, which means that this delay plan has been successful, and it should not be a problem to stay here and chat with Tai Sha for a while.

"Tian Xian, my name is Tian Xian. "Introduce yourself politely.

"Idle ......"

Taisha chewed on the name, human names are not long, but they are difficult for elves to remember, because elf names have their own meanings, and human names are all meaningless symbols for elves.

"Okay!Okay!Now please come with me to meet the Elven King!" Taisha grabbed the map and the equation and walked excitedly to the door.

Hey? This ...... How different from the expected script!

Tian Xian was stunned, "Huh...... That plan, I mean that result, eh...... Maybe it needs to be verified, after all...... It's a very important thing!"

"No need! I've proven it, it's totally doable!" Taisa's eyes lit up, and she had forgotten that she was about to become the talk of the Elven King's City.

Seeing that Tian Xian was still there, Taisha came back and grabbed his arm, "Let's go! The Elf King will be very happy to know about this!"

I'm going to cry every day.

But I'm not happy! )
