Chun Yu took the golden watch in surprise. She looked at the second hand on the watch, which was moving non-stop. Every time it turned, there would be a soft "gege gege" sound.

Long Tianyu laughed lightly: "Solar energy, absorb sunlight to replenish energy, you can continue to use it for an unlimited period of time."

"Solar energy? Can the sun give you motivation? " She saw a small needle swinging in a small sealed dish on the surface of her hand, and asked, "What is that needle made of?"

Long Tianyu explained: "That is a GPS electronic scanner, but it does not have a radar system, it can only be used as a compass. It can always point towards the south, and it is very easy to determine the direction during a survival battle."

Everyone was stunned. The words "compass", "GPS electronic scanner", "radar system" were completely unknown. All of them fell into deep thought for a moment as they mulled over what he had said.

Pure Yu Wan'er's eyes lit up, exuding an extraordinary splendor, she stared at Long Tianyu and exclaimed: "Ah, the compass! The godfather had studied the magnets and ground them into a spoon, which he placed on a smooth copper plate marked with a direction. The ladle made from magnets rotates on the copper plate. Once it stops, the handle of the ladle happens to be pointing towards the south, and the name of the ladle is Si Nan! "

"I once asked my godfather why, and he told me that magnetic needles are made of iron, that iron is metal, that gold is water, and that the north is water, and that therefore the water of the north is the son of gold. Iron is produced by magnets, which are nurtured by yang energy, which belongs to fire and is located in the south, so the south is equivalent to the mother of the magnetic needle. In this way, the magnetic needle must not only care for the mother, but also care for the children. Naturally, it must point in the north and south direction. "

Long Tianyu was completely confused by her theories. The theories of metal, water, yang energy, and fire were all five elements. The ancient theory of yin and yang was flourishing, and the science of natural magnetic fields were all explained in such a way.

Si Nan, the founder of the compass, appeared around the time of the Warring States Period. "An end to the morning and night" was the word used to determine the direction and direction of a battle. "The tube reads," "Above is the benevolent stone, below is the copper and gold." " Copper gold "is a kind of iron ore.

But there are many defects in Sinan, natural magnets are not easy to find, and are easy to lose their magnetism in processing, so Sinan's magnetism is relatively weak, and its contact with the site must be very smooth, otherwise it will be difficult to rotate due to the excessive friction resistance, and cannot achieve the expected guidance effect. And Sinan has a certain volume and weight, carrying it is very inconvenient, which may be the main reason why Sinan has not been widely used for a long time.

However, other people did not understand it at all. Zhang Liang understood a little, and was able to guess that it was Si Nan just by thinking about it. However, the "GPS scanner" and "radar system" at the end did not understand anything at all.

Seeing everyone's stupefied expressions, Long Tianyu realized his mistake and coughed twice. He wanted to take it out immediately: "It's getting late, General Guan Ying has arranged for the cavalry to camp to rest, General Yu Ziqi is in charge of arranging for the troops to rest, Lv Ze, Fan Kuai and Li Shang have sent people to patrol the streets to check on the fish that have fallen into the trap, to rescue the fire source. Zhang Yun has brought people to arrange for the general's residence, to clear out the rooms that they are staying in, each group increase their patrolling in the city, and tomorrow we will notify the various loyal troops to enter the Hangu Pass."

"Yes sir!" The generals immediately stood up and responded in unison.

"Oh? General, Wan-Er still has something to ask. Why are we leaving so soon? " Chunyu Wan'er disobeyed.

Her voice was like the sound of heaven, a few words that carried a tinge of grievance caused all the men to feel dizzy. They thought to themselves: Heavens, the leader of the talented girls of Great Qin, the "ice beauty" can actually speak so obediently?

Long Tianyu gave a slight smile and replied softly, "When we return to our room, let's see Wan'er's reaction, then I'll answer you!"

Chunyu Wan Er's face immediately turned red. Luckily, no one else had heard, but she was also embarrassed and felt her entire body was burning, so she knew what her husband was thinking. She rolled her eyes at him, thinking about her husband who was a hero in bed, and couldn't help but feel that men were sometimes cute too.

All the generals were dumbstruck. They didn't know why even the impassive and elegant Mystic Maiden would blush like a fairy.

Long Tianyu coughed twice, and urged: "Hurry up and carry out your orders, be careful of releasing the enemy soldiers, I will beat you up for your crimes!"

Guan Ying, Yu Ziqi, Fan Kuai and the rest all nodded their heads, turned and left the hall.

The thirty-six personal guards also left, leaving only two women and one man in the hall.

The candlelight was beautiful and smooth, Long Tianyu's eyes were met with Wan'er's and Yi Yi's eyes, his deep love intertwined with each other in the air. Before his body even touched his, the two girls felt as if their souls had been corroded.

Seeing their eyes that were filled with an almost intoxicating desire, a strong sense of accomplishment rose in Long Tianyu's heart. He stuck out his chest and laughed loftily, "Come, let's go back to the room and chat with these two lovely wives while they're at it."

"Really? Wan'er wants you to say what the GSP scanner and the lightning system are. What is it for? "

However, Yi Yi said, "I also want the" watch "with Sister Wan'er?"

Long Tianyu was about to vomit blood. If he had brought more modern technology with his, he would have been able to please his beautiful wife.

With such wild thoughts running through his mind, Long Tianyu pulled the two women's jade hands and walked out of the Main Hall, towards the quiet and elegant backyard. There were elite guards posted everywhere on the eaves of the small pathway house.

Long Tianyu led the two girls directly to a unique pavilion which had just been tidied up. Zhang Yun and Xiao Chuan said at the foot of the pavilion: "Great General, this pavilion is the most elegant and clean room in the entire general's residence, it seems to be a woman's room. After cleaning it up, it would be just nice for the Great General and the two young madams to rest."

"The winding paths lead to seclusion. Yue Yajie Restaurant is indeed a quiet and secluded place." Wan-Er praised him.

Long Tianyu raised his head and looked at the pavilion, then pointed at the two generals Xiao Chuan and Guo Dian: "All of you can leave, retreat the twenty steps to the sentry post." He did not want the guards to hear his words while he was enjoying his room.

Zhang Yun, Xiao Chuan and the others did not dare laugh, and tactfully retreated. The elite soldiers of the hidden sentry in the pavilion retreated twenty steps.

Long Tianyu no longer cared about the others and only took the two girls up the stairs. He pushed the door open and entered the pavilion, the interior layout was exquisite and unique, it caught his eye first, there were a few silk and bamboo instruments hung on the walls of the room, on the table were Lin Lang books, on the dark red table laid a zither, and it was likely that the person who lived here was a strange lady who was proficient in sound waves.

Could it be Yueyao? It can't be, Yueyao had only entered the Hangu Pass for one day and she had already followed the army to attack Xianyang. No matter how much Xiang Yu wanted to curry favor with the beauty, she couldn't make up her mind to go through all this in detail.

Who could it be? Long Tianyu fell into deep thoughts …

Xue Mengyi was one of the four famous girls in the Great Qin, and was well versed in music music, and was no less knowledgeable than the talented girl, so she was the first to walk to the side of the silk bamboo, took down a piece, and blew lightly, praising: "What a good music bamboo, just listening to the purity of this syllable, it is known that Master is definitely someone who knows his place, and is not inferior to Yi!"

Pure Yu'er came to the zither, after all she was proficient in the zither, her white jade like hands lightly strummed the strings twice, the sound was soft and melodious, she couldn't help but praise the zither, suddenly she saw a row of characters carved on one end of the zither, the mouth of the cherry blossom said: "Since ancient times, women have had many thin lives, leaving Green Tomb to the evening!"

"Huh?" Long Tianyu was suddenly shocked, this sentence was … Wasn't this the same sentence that he had said to Yu Ji back then?
