The greatest emperor of all time? Even in modern times, he still has to work!

"Really? Then you must take good care of yourself in the future, and never get sick again~"

Pinyuzizi blinked his big watery eyes and said in a baby voice.

He stretched out his chubby little hands and gently stroked Ying Zheng's face, like a well-behaved kitten. This child's small body always exudes a sweet milky fragrance that seems to melt people's hearts.

Ying Zheng just felt relaxed and happy, and was in an especially good mood.

"Yes, I understand." Ying Zheng responded with a doting look on his face.

However, the innocent Pinyu cub actually imitated Ying Zheng's tone and said in a baby voice: "Well, I sent it too~~~~"

That look is so cute that it makes people laugh.

Ying Zheng did not feel offended or threatened by the child saying the word "朕". On the contrary, he thought the little guy in front of him was so funny and cute that the usually majestic emperor could not help but burst into laughter.

"Hahahaha!" Ying Zheng's hearty laughter echoed in the air for a long time.

The officials of the Qin court following behind were stunned at first when they heard the sudden laughter. They looked at each other, feeling as if they had seen a ghost, and a slight chill ran down their backs.

Your Majesty, please don't laugh, we are scared.

……

Daqin, the 27th year of Emperor Qin Shihuang, Qilin Hall.

In the simple palace, modern light bulbs are lit, and the bright and soft light illuminates the entire palace. The originally dim corners are dispelled by this light, revealing exquisite murals and carvings. The walls depict scenes of ancient wars, with warriors wielding weapons and fighting bravely; the ceiling is carved with mysterious patterns, as if telling a long-ago story.

These modern light bulbs form a sharp contrast with the ancient palace. They are like messengers that travel through time and space, bringing a different kind of vitality and vigor to this long-silent building. Under these bright lights, people can appreciate every detail in the palace more clearly and feel the profound heritage of history.

Ying Zheng was sitting behind his desk, reading through the pile of memorials attentively. His brows were slightly furrowed, his eyes were sharp and focused, and he kept writing important comments on the memorials with a red pen in his hand.

At this time, standing at the door were the mighty Meng Tian and several fully armed guards. They stood motionless like sculptures, always guarding the safety of the lord of the world.

Since Zhao Gao had been dealt with before, all the eunuchs in the palace were replaced. It would take time for the new eunuchs to get familiar with the palace affairs, so there was no suitable person to serve His Majesty. So, Ying Zheng ordered the palace maids to serve His Majesty in daily life, while some trivial matters such as delivering messages and running errands were left to the guards.

Ying Zheng had always had little interest in the affairs of the harem and rarely set foot there. As a result, even though he was only accompanied by guards, he did not think there was anything wrong with it.

On the contrary, guards seemed to be more useful than eunuchs. They were quick on their feet, efficient and honest in their work, and were directly managed by Ying Zheng, which reduced many hidden dangers.

Ying Zheng was still thinking about whether he should get rid of eunuchs in the future, when something unexpected happened.

Suddenly, a deep blue vortex appeared in front of Ying Zheng, as if it was a passage to another mysterious world. Ying Zheng was startled at first, but soon he showed an irrepressible joy on his face.

Meng Tian, ​​who had been guarding the door, reacted extremely quickly. Almost at the moment the vortex appeared, he rushed into the hall like an arrow, and closed the door from the inside as quickly as possible to prevent outsiders from seeing this strange sight.

"Your Majesty, Xi is back." Along with this shout, a figure slowly stepped out from the mysterious vortex. This person was Xi, and his face was filled with irrepressible joy and excitement.

As soon as Xi appeared, he knelt on his knees without hesitation and respectfully performed a standard kneeling ceremony to Ying Zheng who was sitting high on the dragon throne above him. His movements were full of piety, as if the person in front of him was the supreme being in his heart. At this moment, Xi's heart was filled with an emotion called joy.

Upon hearing the news of Xi's return, Ying Zheng, who was originally sitting on the dragon chair handling government affairs, stood up suddenly. He cast his eyes eagerly at Xi in the hall, his eyes flashing with surprise and joy. Then, Ying Zheng took a big step and walked quickly towards the hall. His steps were steady and powerful, and every step revealed his desire and concern for Xi's return.

"My dear, you are finally back! I have been waiting for you for so long!" Ying Zheng walked forward quickly with joy on his face, held Xi's arm tightly with both hands, and carefully helped him up from the ground.

"Your Majesty!" Xi looked at Ying Zheng's familiar and majestic face. Tears instantly blurred her eyes. Her voice choked, as if her throat was blocked by something. It took her a long while to utter these two words with difficulty.

At this time, Xi had already burst into tears, and his tearful eyes made people feel distressed. His lips trembled, as if he had thousands of words in his heart that he wanted to express, but he didn't know how to start for a moment.

"My dear! Isn't it the same for me? These days, I have been missing you all the time!" Ying Zheng was also very excited, with tears flashing in his eyes. He held Xi's hand tightly, as if he was afraid that the person in front of him would disappear again if he let go.

"Your Majesty, Xi's trip to the afterlife this time really broadened my horizons and I learned a lot of new knowledge. Do you know..." Xi calmed down a little, took a deep breath, and said slowly.

"How to maintain an aircraft? How to operate a tank? The importance of gun research and development?"

Ying Zheng was indeed shocked by what Xi said about future events, such as passenger planes that could carry people flying in the sky, fighter jets used in wars, aircraft carriers, and even the heavy tanks that dominated the land. He was shocked, curious, and wanted to possess them.

However, the knowledge that Xi brought back didn't seem to explain how to build these things. Even for the basic accessories, there didn't seem to be detailed production methods.

"My dear, these are good things, but how do we use them?"

"Uh..." Xi was speechless for a moment. The courses he found didn't teach these things.

To be honest, it took a lot of effort for an ancient person to accept this knowledge, and the knowledge on the Internet is not complete.

Now I have briefly talked about the key courses, which require VIP membership or have a clear price tag of a few dollars, and the knowledge is divided into blocks. If you take a course on engines, it will not teach you how to assemble a generator on an airplane. This is another course and has a different price.

To put it simply, modern knowledge has a mechanism to prevent self-study.
