The sky is round and the four seas are boundless. Another way is that the sky is like a dome, covering the four wilderness...... In countless ancient legends in the Oriental world, it is unmistakable that the sky above the head of human beings is a cauldron lid, and the square land under the feet is the boxy land.

Such a notion, so ingrained that no one has ever doubted it. Even those Spring and Autumn princes and holy ancestors, no one seems to have put forward any other ideas.

Even if the soldiers of the Han army were not well-educated people, they were at least accustomed to these things that they had known since childhood, and they never felt that there was another possibility.

But now, there was a guy who came out of nowhere, and suddenly said in front of all of them that the earth was round, which made anyone who heard it probably couldn't help laughing.

On the brutal battlefield just after the end of the Great War, laughter suddenly broke out, which was originally very incongruous. But no one could stand it. This is ridiculous!

"What did he just say? Round...... Hahaha...... Round?"

"That'...... Did he and his prophet not roll back and forth in the night when they slept? Scold! ”

"Forget it, let's not kill him. A crazy person is just ....... ”

The sword was withdrawn, and those who spoke wild words were spared destruction. However, the next moment, everyone heard Yuan Zhao say something calmly.

Actually, he was right. What the prophet wrote was kind of interesting. ”

Everyone was stunned. Someone opened his mouth wide and looked at his idol in great surprise, suspecting that everyone's ears were hallucinating.

"Huh! Don't be so surprised, even if it sounds a little incomprehensible...... But I believe that in the future, you will all understand. ”

The soldiers who followed were all staring at each other, not because they didn't want to understand, but because it was really difficult to understand these distant unknowns. However, this did not prevent them from blindly following Yuan Zhao. Since Master Hou said that this is right, it is right. After all, even such miracles as flying in the sky and thunderbolts in the earth, they have witnessed them with their own eyes, and they do not need to keep their doubts in front of this all-powerful man.

Buyano was a little surprised. He never thought that the prestige of the young commander in front of him would be so great, and whatever he said, these elite soldiers and strong generals under his command quickly changed their attitudes and echoed their voices. And, to his incredibleness, he agreed with his own statement! It seems that I have known it for a long time, and it is a matter of course.

I remembered the behemoth that I saw flying in the sky yesterday, and the terrible weapons that thunderbolted and wounded the Persian army in large numbers. Buyano suddenly felt that his heart, which he thought had mastered the secrets of heaven and earth and had become incomparably stronger, was a little quickly shaken.

"Your Excellency, Honorable Commander, you are such a powerful person. So, do you think there is any value in the information I have offered? ”

Buyano raised his head and looked at Yuan Zhao again, with some mixed emotions in his eyes. He had long heard that there was an extremely powerful figure in the Han Empire, and when he saw it today, it was really extraordinary.

"It can be said to be priceless, or it can be said to be worthless!"

Yuan Zhao answered his question very clearly. He smiled quietly, already vaguely understanding what the man who had come to risk death wanted to make.

Sure enough, Buyano straightened his somewhat tattered clothes. He saluted solemnly, and then said in a earnest tone.

"I am willing to dedicate the wisdom and knowledge of the universe inherited from the prophets to the Han Dynasty. I beg your order to stop the attack on the Persians. If I can give a grace period, I will persuade His Majesty the King of Persia to withdraw his troops, and from then on the two countries will defend one side and not offend each other. Is this possible? ”

All the generals who stood by the sword also turned their eyes to Yuan Zhao, and the victory at Yumen Pass gave them great confidence, and now no one was willing to stop this war. The blood debt owed by the Persian army has not yet been repaid, where can it be so good as it gets!

Yuan Zhao did not disappoint them. Before the troops left Chang'an, he had already made a comprehensive strategic deployment, so how could he easily change it. He pointed to the endless distance, where the beacon fire of last night was gradually extinguished, and the brave and invincible soldiers of the Han army were about to embark on a distant journey from here.

"Our Han Empire has always done things from beginning to end, and since the war has begun, we must get a satisfactory result before it can end. The Persians have made a great deal of blood and will be severely punished in order to be worthy of the justice of this world and the dead souls. ”

Yuan Zhao's tone became stern. Buyano watched uneasily at the young commander's edge, and his heart sank. Then, he heard the extremely harsh conditions of the other party.

"However, as long as the king of Persia orders the whole army to tie up his hands and bind himself to come to plead guilty. I can open the net and leave a legacy for the Persians, and I will not kill them all. Moreover, you and your disciples are willing to return to Chang'an with me and serve the Han Dynasty from now on. ”

"Why? I can give everything I know and learn from the prophet to the Han Dynasty in exchange......! ”

"Huh! I don't want a pile of waste paper, I want people! ”

Yuan Zhao laughed coldly. Since this strange guy in front of him has sent it to the door himself, he won't let it go!

Needless to say, the Persian army's strong combat effectiveness and those siege equipment that relied on various physical principles must have been contributed by figures like Buyano.

The development of practical science in later generations originated in the Western world in many ways. Many of the many clever people who have appeared in the long course of history are demonic geniuses. Awesome and awe-inspiring.

Yuan Zhao never thought that he could do everything with his innate advantages. The discovery of the mysteries of the universe and the process of technological development require people who are truly gifted in this field to accomplish it. In many cases, he has many ideas that he wants to realize, but he is simply unable to do anything about it. Just a few prototypes of hot air balloons have already exhausted him and made him miserable. If you want to tinker with something more advanced, with the current talent pool, it is simply impossible to achieve.

The reason why Yuan Zhao made up his mind to fight a war with Persia was to conquer the country. In addition to taking revenge on the other side for its unprovoked aggression, the main purpose is to take this opportunity to set foot on the Western continent and pick the flowers of civilization that have bloomed there.

Under the successive rule of several Western empires, what kind of fruitful fruit has been produced in that land? Yuan Zhao really wanted to see them with his own eyes, and if possible, he would do whatever it took to grab them all to the big man!

Buyano lowered his head. He felt the other side's determination to war, and he also sensed the other party's great ambition. After a long time, he only asked in a low voice.

"So, you're going to kill me now? Or will you be a prisoner?"

"I will neither kill you nor imprison you. Instead, they'll let you go back. Now you're good to go. ”

Buyano was surprised. He hurriedly asked in disbelief, "Your Excellency, what you said is true?"

"Of course. When you return, you can choose to persuade the king of Persia to surrender. It can also help him continue the next war. It's OK...... Bring your followers to the Great Han. Hehe, it's all in your own choice. ”

Yuan Zhao's attitude was very clear, he waved his hand, signaling to open the shackles for Buyano and let him leave freely.

Confused and surprised, Buiano walked away. He walked through the battlefield strewn with the corpses of countless Persian warriors, and gradually walked away in the smoke and dust.

"Yuanhou, is it really that important for such an ordinary barbarian?"

The soldiers were full of puzzlement. Yuan Zhao's eyes were shining, and he carefully flipped through a few pages of the parchment paper in his hand, and then put it into his arms as if he had found a treasure. His face was full of joy.

"It's unexpected! In this day and age, there are people who have recognized this knowledge, which is remarkable! Well, yes, this man is very important, and if he and his followers can really surrender to the Han Dynasty, it may bring us great benefits beyond imagination! ”

Although the soldiers couldn't think of any great benefit that the prisoner who was almost killed would bring, they also paid attention to it when they saw that Yuan Zhao attached so much importance to it.

But why let him go? What if he escapes, or is killed when he returns? ”

"Don't worry. Such a talented guy won't die so easily. And when it comes to escaping, where can he run? Soon after, when the entire western continent on which the Persian Empire was located trembled under the iron hooves of the Han army, no one could escape the grasp. ”

Feel the extreme confidence in his tone. All the people in armor agreed in unison. Their invincible commander has issued the battle horn, and it is the task of the warrior to fight fearlessly until all enemies are completely conquered!

The news of the battle of Yumen Pass, after dawn, was quickly spread in all directions. As people from different sides receive information one after another, the shocking emotions in their hearts are naturally different

However, the fortress of Dunhuang City, which had been besieged by heavy troops for more than a month, had no way to learn this exciting news.

The direction of the rising sun in the east brings a hint of warmth. As the Sima in the army of the Western Regions, Zhang Qian, who led the rest of the men and horses to guard this lonely city, endured hunger, cold and pain, and looked at the direction of Chang'an again, but he felt unusually desolate in his heart.

He felt like he was a little too strong to hold on. If it weren't for the tens of thousands of people in the city behind him, Zhang Qian would have wanted to lie in the city now and never wake up again.

Dunhuang and Yumen Pass are separated by no more than 100 miles, however, looking at the boundless army besieging the city, he understands very well that unless the Han Dynasty does its best, it will be difficult to compete with the king of Persia in the Western Regions.

"Perhaps, here and now, is where I was martyred!"

Seeing the sudden abnormal movement of the Persian army, Zhang Qian pulled out his war knife again and mustered up the last courage to fight.
