"......"

After Ryuuji left, Tang Yu rested for a while, and then continued to solve the mystery of the Shrine, from the evening of the afternoon to the hazy night, I don't know how long it will last. However, Long Xiaoyun always accompanied him, and when he was sleepy, he put his hands on his cheeks, and he had to see it clearly, thinking to himself what the biggest secret in this hero building would be?

"Ah, could it be ......" When Long Xiaoyun was bored, he shouted in surprise, and at the most critical moment, Tang Yu's hands trembled, but it was this trembling that the core iron shell of the demon shrine was actually opened. Tang Yu couldn't believe it, he couldn't believe his eyes, because he saw ...... Then. "Uh-huh......" Long Xiaoyun was so sleepy that he yawned a little unsupportively, and then asked Tang Yu, "Brother Yu'er, is the biggest secret in the Hero Building that there are no secrets?"

Late at night, in the dead of night, quietly, silently.

"Thousand Spy Umbrellas!"

Tang Yu saw the magic shrine under the long pit underground, and there was a literal description in the middle: Thousand Spy Mystery (umbrella), given to fate (person). Then he picked up the 'biggest secret' in the Hero Building, and he couldn't put it down, or he had dreamed of it, but now he finally got it by accident. Who knew that after he came out, the special weapon of the extreme agent in his hand immediately attracted Long Xiaoyun. She instantly fell asleep, she was extremely excited throughout the whole process, and she also couldn't put it down after directly "grabbing" it, until the door of the house, she still couldn't bear to return this thing......

Tang Yu thought to himself, if it weren't for Long Yun's little sister's 'ah' shock, how could he get such a rare and strongest espionage intelligence weapon, if it was Tianyuan, but it was not her place, just ask who else it was.

"Do you like it?"

"I love it!"

"Then use it for you!"

"Hey, what are you kidding Brother Yu'er!"

"Sister Xiaoyun, if it weren't for your great help just now, I wouldn't have been able to open this ever-changing magic shell!"

"Yo yo yo, my mouth is weird and sweet, I just want it, why do you have so many excuses...... Hee-hee-hee. ”

"Haha, these days, thank you so much for taking care of me, if you hadn't secretly helped me......"

"You know again!"

"Thank you for helping me pay off my debts. ”

"Ahh ”

"No matter what, I want to thank you!"

"Why are there so many excuses......"

"It's nothing, I'm just ......"

"Don't be afraid, don't be afraid, with me, they will dare to bully you again......"

“......”

As he spoke, Tang Yu became a little lost, remembering that he had 'fallen' into the dust here, and it had been a few days.

The other side. Long Xiaoyun continued to play with the Thousand Butterfly Umbrella, full of will, and his interest was always very high, and he comforted him with a big grin, "Good fish, you don't have to worry, this place will soon change its name and surname, although dismissal and layoffs are also necessary, but with me, there will definitely be a bite of food for you......"

"Layoffs?" Tang Yu was puzzled, "Why are you being dismissed?"

"This 'wind, fire, thunder and lightning' button ......" Long Xiaoyun was holding a thousand butterfly umbrella that was only the size of a handle at this time, carefully weighing the usage skills, and not paying attention to what others said at all. And as soon as Tang Yu heard her say wind, fire, thunder and lightning, he hurriedly stopped, "Don't press!" "Oh, don't turn!" "Don't be awkward!" "Beware, don't dial!" "Be careful, don't order!" "......"

"Wow, wow, there is also this 'blood rain red cardoon' machine......" Long Xiaoyun seemed to be endless, constantly testing on the edge of danger, but fortunately, Tang Yu was closely 'monitoring' on the side, so as not to have a safety accident.

After a while, Tang Yu took the initiative to take the Thousand Spy Umbrella with a long handle, zoomed in, zoomed out, zoomed in, and completely demonstrated it, and then told Long Xiaoyun the key to attack and defend without reservation. In this regard, Long Xiaoyun said strangely, "Brother Haoyuer, how do you know this?" Tang Yu smiled and said lightly, "I read it in the book!" "What else does the book say?" Long Xiaoyun simply made inches of progress, completely ignoring the faint moonlight, the night was like water, and there was no third watch and almost five watches.

In order to be concise and get twice the result with half the effort, Tang Yu simply completed the whole process of 'acting' the Thousand Butterfly Umbrella:

First, dismantle. Secondly, assembly. Finally, it is disassembled and assembled at the same time, and detailed instructions are added......

"Now, look, this is the core axis!"

Long Xiaoyun nodded, completely silent.

"The size of the spy umbrella is controlled by the variable axis, as large as an iron pestle, smashing, percussion, horizontal lance, and breaking the wall...... As small as a dagger, stab, tease, hook, and cut ......"

Long Xiaoyun listened to it with relish, and asked if he didn't understand. When she heard Tang Yu say that the Thousand Spy Umbrella could be used for offensive and defensive battles, she asked the root of the question and said seriously, "What is the principle?"

Tang Yu thought about it and paused slightly. Long Xiaoyun thought that he finally had something he didn't understand, so he was secretly smug and teased, "Haha, Brother Haoyu'er doesn't know!" Unexpectedly, Tang Yu smiled slightly, and said two words, "Ejection!"

"Catapult?" Long Xiaoyun said stunned, "What do you mean by catapult!"

"Have you ever played with a slingshot?"

Long Xiaoyun replied, "I've played it, it's very fun!"

"It's good to have played, the slingshot has a rubber band, an iron (wood) bracket, and the most important thing is a projectile or a marble...... Tang Yu wanted to tell her something too complicated, but Long Xiaoyun couldn't understand it, so he replied simply, "Ejection is to change the tension of things, and send out a deadly hidden weapon through impact, otherwise it will be absorbed!" Long Xiaoyun continued to listen quietly after a "oh" sound. Next, Tang Yu explained more thoroughly, teaching him to identify the parts and components in the umbrella of thousands of spies and their composition. He said, "You see, the springs, the firing pins, the fire hydrants, the hooks, the buttons, the triggers,...... By the way, there are also flying claws, lassoes, steel ropes, wires, and essential ,...... for escape"

Here's the problem.

Long Xiaoyun listened to the knobs corresponding to the 'Heavenly Stems and Earthly Branch' and 'Twelve Birthdays', as well as the specific knobs corresponding to the thousands of spy umbrellas such as 'Bagua Four Elephants and Nine Palaces' and Qimen Dunjia Technique, and especially remembered it, "Hehe, what is the 'wind, fire, thunder and lightning' ......?"

Tang Yu was unhurried and taught her, "You disassemble and assemble it for me to show ...... first."

Long Xiaoyun had long been eager to try it and started immediately. Who knew that the first step, she was wrong. "No, no, you must first assemble the silver needle, darts, iron cones, lotus seeds and other offensive hidden weapons to the machine slot, and then connect the components to the core shaft, and then tighten the trigger button...... Do it again!" "Okay!" Long Xiaoyun didn't say a word, remembered the essentials and started quickly, and as soon as he finished assembling the Thousand Spy Umbrellas, he discovered the key point of the assembly order:

That is, she does not need to be busy loading hidden weapons such as silver needles to the shooting machine slot in a panic, and she can immediately attack the opponent, which can be described as a preemptive strike and kill the enemy.

"Hahaha...... What a great fish brother!"

"Where, where, Sister Xiaoyun is talented and intelligent, and she learns quickly!"

It's finally come to an end.

Tang Yu said solemnly, "The four mysteries of 'wind, fire, thunder and lightning' are the most powerful part of the thousand spy umbrellas, and the terrifying stunt 'Blood Rain Red Kou' is also a wonderful method that cannot be moved, if you are not careful, not only will the opponent be killed on the spot, but even the owner will be seriously injured......

Long Xiaoyun nodded, as if he understood whether he understood or not, "Oh, in short, if it is not a matter of life and death, it must not be used!"

Tang Yu suddenly touched Long Xiaoyun's head, indicating that she was really smart and clever. In short, Long Xiaoyun was really grateful in his heart, and swore that "Brother Yu'er, if I really become the king of intelligence agents in the future, I will definitely repay you well......" "Silly girl, let's talk about it then!" Tang Yu smiled, thinking that there was no such easy thing in the world.

Soon, it was almost dawn, and Tang Yu instructed Long Xiaoyun to hide the Thousand Spy Umbrella well, and then went back to work......
