"I'm very sorry, Your Majesty the Emperor." Yan Fei looked at Li Shimin with calm eyes. "I didn't kneel down and salute in my country. I am not a citizen of the Tang Dynasty, so I can only pay tribute to you in my own way."

Li Shimin held one hand behind his back and the other hand in front of him without expression or words, but Yan Fei could feel a sense of anger being gradually gathering.

"Your Majesty, I'm here to help the Tang Dynasty deal with the Turks." Yan Fei smiled slightly, "I'm very honored to be received by Your Majesty. I have a few gifts to give to Your Majesty."

"Oh?" Li Shimin finally said, "Didn't you have already given the horseshoe?"

"That's just a little thing." Yan Fei smiled and nodded. "How can a few broken iron pieces be considered gifts?"

Yan Fei turned his head to look at Qin Qiong who looked anxious, "Duke, the things I brought below are on the ox cart outside the imperial city gate. Please send someone to get it."

Qin Qiong did not reply, but looked at Li Shimin.

"Go." Li Shimin waved his hand, turned around and returned to the chair to sit down. "I want to see what gift it is. If I can't satisfy me, I'll chop your head with a sin of disrespect."

"The gift will definitely satisfy Your Majesty." Yan Fei pushed back without being humble and arrogant. "As for cutting his head, there were many people who wanted to be on the ground, but unfortunately no one has ever succeeded."

Although Li Shimin was the emperor, Yan Fei was not afraid at all. Before, in other time and space, I didn’t know how many people wanted his head, but unfortunately there was no one who succeeded. All he pursued was to go home.

‘Bang!’ Li Shimin slapped the handrail heavily, and a large number of fully armed guards flocked in to surround Yan Fei. The cold light of swords, guns, swords and halberds flashed and pointed at Yan Fei, and the sound of golden spears burst out in an instant.

The atmosphere in the hall became tense instantly, as if as long as Li Shimin gave the order, Yan Fei would be cut into meat paste.

Faced with the dangerous situation in front of him, Yan Fei didn't even blink his eyelids. He took out a cigarette firer and lit one, spit out the smoke ring and asked casually, "It's almost dark, Your Majesty, let's take a look at the gift first."

"Hahahaha~~~" Li Shimin suddenly burst into laughter. "I have been fighting all over the world for many years, and I have seen all kinds of heroes. It is the first time I have seen such a bold one like you. It's great, so let's take a look at your gift first."

The guards retreated like a tide, and the hall quickly returned to quiet, as if everything had never happened before.

Yan Fei's gifts were all in boxes. A group of guards carried several large iron boxes into the hall and put them down. A group of people surrounded Li Shimin, worried about the dangers in the box. Yan Fei used the boxes with passwords, and they couldn't open them to check before.

Yan Fei came to a box with D characters, entered the password to open the box, and took out a set of metal armor from the inside.

"Is this your gift?" Li Shimin looked at the strange-shaped armor with a look of disappointment. "I don't lack armor here."

Yan Fei finished setting up a complete set of plate armor, turned around and looked at Li Shimin and smiled, "Your Majesty, please find someone to try it on. Then use the swords, guns, swords, halberds, bows, arrows, horses and spears at will. As long as it can cause substantial damage to the armor, I will give you another 10,000 sets for free."

"Hmph." Li Shimin, as the emperor of the horse, was quite interested in this. After waved his hand, a tall and strong guard came forward and put on the entire set of plate armor according to Yan Fei's instructions.

"It's very light." The guards were dressed neatly and said in confusion, "It feels lighter than the Mingguang Armor."

This set of fully protected plate armor from beginning to end is indeed not as heavy as it looks, because Yan Fei used alloy materials when he was building it, which not only had amazing hardness but also had very light weight. It was engraved with extremely complex cloud patterns with lasers, and advanced techniques such as polishing coating, which looked extremely beautiful and majestic.

After obtaining Li Shimin's permission, a guard grew his hand and slashed it on his breastplate with a knife.

"Put harder." Seeing that there was no trace on the surface of the armor, Li Shimin shouted and asked the guard to attack hard.

The guard gritted his teeth and held the knife in both hands, and looked at his colleague's breastplate. With a metallic attack, the high-quality sword broke directly, but the armor was not damaged.

Next, various weapons took turns to fight, and the fire was cut from the plate armor splashed everywhere but there was no obvious damage. This powerful defense ability made Li Shimin nod slightly, "Good."

After the experiment was over, Yan Fei asked the guard to take off the plate armor. Then he took out a long sword with exquisite workmanship and cold light from another box with beautiful quenching cloud patterns.

The guards were very nervous and quickly protected Li Shimin. Yan Fei slashed directly at the plate armor arm.

The light of the knife flashed, and a deep mark was left on the armor arm. The second knife cut down and directly broke the defense. When the third knife went down, the armor on the arm was directly cut off by one knife.

Li Shimin pushed away the guards in front of him and walked to Yan Fei, reached out to take the long sword handed over by Yan Fei and looked at it carefully. After a moment, he suddenly turned around and held the knife in his hands and slashed hard on the breastplate.

A deep knife mark was cut out from the breastplate that had not been broken before facing various weapons. Li Shimin closed the knife and looked it carefully and praised, "What a good knife. How many do you have?"

"There are as many as you want. And the quantity is very high." Yan Fei responded with a smile, "The premise is to open up my way home. As long as I can defeat the Eastern Turks as soon as possible, I can go home."

"Not enough." Li Shimin shook his head and sighed, and casually carried the long knife made of alloy, chrome-enhanced blade back to the chair. His meaning was obvious. A set of armor and a knife, and horseshoes were not enough to guarantee defeating the Eastern Turks.

"Your Majesty will definitely like this last gift." Yan Fei chuckled and said, "With him, the success of the raid on the Eastern Turks has increased by at least twice."

"Oh?" Li Shimin, who handed the long sword to the eunuch in front of the imperial eunuch, asked in confusion, "What's the matter?"

Yan Fei did not respond and directly opened the remaining boxes.

The remaining boxes contain components of the drone, and Yan Fei quickly assembled them.

"You two." Yan Fei pointed at the two guards not far away, "Come here to carry this outside, and do not bump into it with a gentle movement. This thing is very precious."

Li Shimin's interest was also distorted. He walked over and looked at it curiously before signaling the guards to carry him out of the hall, "What is this? What is it for?"

"This is a drone." Yan Fei held the workstation computer and remote control and reached out to signal Li Shimin to go outside the hall. "As for what it is, you can see it with your own eyes when your Majesty."

At this time, the sky outside was approaching dusk, and a sunset in the distance was gradually sinking. The entire Chang'an City was about to enter night mode.

Outside the Tai Chi Palace is a large open space paved with stone slabs in front of the hall, which is definitely enough for taking off and landing drones.

After adjusting various parameters and turning on various devices, Yan Fei controlled the drone to take off, then switched to self-driving mode, and circled around the palace in mid-air.

Everything around was alarmed when the drone took off. Even Qin Qiong and Li Shimin, who had been calm before, were stunned. As for the eunuchs and guards, they were even more panicked and screamed, but Li Shimin shouted loudly and calmed everyone down.

This is also impossible. In the concept of people in this era, there is nothing but birds. At this time, I was naturally panicked when I saw the drone flying into the sky with my own eyes.

"Please look at your Majesty." Yan Fei opened the workstation computer and signaled Li Shimin to look at the computer screen.

"...What is this?" What appeared on the screen was a real-time image of the ground transmitted back by the drone. Because I looked down from the sky, although I felt a little familiar, Li Shimin didn't understand what this was for the time being.

"This is the imperial palace I saw from the sky." Yan Fei pointed at the large palace on the screen. "This is Tai Chi Palace."

"What?!" Li Shimin and Qin Qiong beside him both exclaimed in surprise. This was really incredible, and he had never even thought about it.

Yan Fei operated the keyboard a few times and pulled the image closer and enlarged. He could clearly see the crowds in the square in front of Tai Chi Palace from the screen. Even Yan Fei and the others could see it very clearly.

"The battery life of this drone is as long as five hours, and you can search for a range of hundreds of miles nearby." Yan Fei chuckled and said, "With this thing, if you go to the grassland, whether it is water source road or cattle and sheep, you can be discovered in advance. Of course, it also includes Jie Li's golden tent location."

"Jie Li's golden tent!" Li Shimin's breathing became obviously rapid, and his eyes were fixed on the screen in front of him. "Very good, I like this gift very much!"

In modern warfare, the right to control information was very important, and the same was true in ancient warfare. Whoever can grasp sufficient detailed information in advance can grasp the initiative. Even if the weak enemy is strong, you can easily avoid the main force of the strong enemy and find its weaknesses to attack.

This is the effect that drones can do. With the help of this thing, when you go north to raid the grassland, you can easily avoid the gathering points of the Turks, easily find the water source and their target, Jie Li's golden tent.

The Eastern Turks claimed to have hundreds of thousands of string control men, which is indeed very powerful. However, these string control men are basically ordinary herders. They have to take care of their cattle, sheep and horses to find fat water and grass to graz. It is impossible for them to stay near Jie Li's golden tent every day.

Under normal circumstances, only a few thousand people were stationed near Jie Li's golden tent, and even if it was slaves and others, there were only more than 10,000. As long as the Tang cavalry could approach without knowing it, then a surprise attack would definitely be able to successfully capture the unprepared Turkic golden tent.

If there were only horseshoes before, Li Shimin was unwilling to take risks with his precious cavalry. But if the drone had the lead, the possibility of success would be very high.
