Seeing Wu Weiyi's strategy for the first time, Du Yu can be said to be convinced of Wu Weiyi. So, he decided to follow Wu Weiyi's advice and return to Mapicheng. As soon as this order came out, all the soldiers and the people accompanying them began to work in the camp at the foot of Qingcheng Mountain to tidy up and clean up. I saw that someone pushed the "flamethrower" that had made a great contribution to the camp from the slope. When everyone saw the strange appearance of this thing, they immediately rushed forward to see its appearance.

I saw that this fire-breathing instrument is like the shape of a cow, the cabinet of boiled copper, standing with four legs, the front and back of the cabinet body are provided with two cones, the front barrel is large, the tail barrel is thin, and there is a small trick behind the tail barrel, such as the size of millet grains. The front cylinder is a round mouth, with a diameter of about half an inch, and there is a small mouth on the side of the cylinder connected to the cover, which is the oil injection place. The front cylinder faces outward and a transverse cylinder (original piston machinery) is placed horizontally, which communicates with the cabinet.

Only the audience exclaimed in amazement:

"This thing is so good! I really didn't expect this thing to be able to resist fire! Mr. Wu can create this kind of thing, he is really a god! ”

Wu Weiyi heard everyone talking on the side, so he stepped forward and explained to everyone:

"It's not a miracle, it's called the 'Fire Oil Tank'."

I saw Wu Weiyi open the oil filling port of the cabinet. He picked up a branch from the ground and put it in. When he pulled out the branch, he saw that the tip of the branch was stained with a layer of black oily viscous liquid.

"This thing is fierce fire oil, which can be controlled by air, and when it encounters an open flame, it can turn oil into fire and gush out. First plug the small hole in the back cylinder, and use this cylinder (piston) to luck in the cabinet. Then use the open flame to lead it outside the tube. The air in the cabinet is full and the fire oil breaks through the plug at the mouth of the cylinder, and the fire tornado can be sprayed out from the mouth of the cylinder. ”

Wu Weiyi said as he pointed the nozzle towards the open ground and demonstrated the operation again. Sure enough, a fire tornado erupted from the small hole, and the place it swept away was instantly turned to ashes. Seeing is believing, and even calling out miracles.

In fact, Wu Mou was only a few days ago when he and his retainer Mo Zhai were patrolling the mountains to inspect the terrain, and suddenly found that there was a black oil well exposed on the surface of the ground. I told him that this was a fierce fire black oil, and shared some thoughts. I didn't expect that Mo Zhai would really start to study it, casting molds and burning fire to pour copper, and then building one. If you want to say that this miracle is mysterious and magical, it must be Mo Zhai. ”

Just as everyone was still gathering around the fierce fire oil tank, they heard a crisp sound of the Qiang flute from the hillside.

Everyone stopped talking, looked up at the sound, but saw that Du Yu was standing alone on the hillside playing the Qiang flute, the flute sound was melodious and tactful, and there was a faint sense of pity and melancholy in it.

Looking back at the top of the slope with everyone and listening for a while, Wu Weiyi knew that the princess must be in a mixed mood at this time. The father was killed but could not enter the filial piety of the son of man, they were clearly brothers and sisters, but they wanted to meet each other here. He only wanted to avoid trouble, and then he had to take refuge elsewhere. Don't say it's her, it's a person of grass and trees, hard-hearted, how can it not be moved and lamented.

Wu Weiyi climbed the hillside, came behind Du Yu, and whispered to the princess:

"The wind in the mountains is strong and damp, please take care of your body with Her Royal Highness the Princess. In the future, I am afraid that there will be many difficulties and obstacles along the way. Now the princess is the only hope of the people of Shu, and I hope that the princess will not be too tired. ”

Du Yu heard someone coming behind him, so he stopped the sound of the flute. turned his head to take a look, and saw that it was Wu Weiyi. Suddenly he seemed a little restrained:

"I don't know if Mr. Wu is here...... Bengong was very bored in his heart, and originally wanted to climb high and look far away here, and dispel the dull atmosphere that had accumulated in his chest recently. But I don't want to see the corpses of the soldiers of Shu here again, thinking that they were originally just ordinary people of Shu, but they only died here because of their brother's selfish desires. Although it was helpless, I couldn't help but feel nostalgic for a while. Then the Qiang flute was played, hoping that these soldiers who died in vain could be buried here and no longer have the disturbances of the world. But he never thought that it would disturb Mr. Wu, which made Mr. Wu laugh. ”

Wu Weiyi looked in the direction of Du Yu, and sure enough, he saw hundreds of corpses lying on the slope under the hillside, and there was still sporadic smoke in some places. And some of the corpses were even burned beyond recognition, which was unbearable to look at.

Seeing the scene in front of him, Wu Weiyi couldn't help but sigh:

"The hometown where Wu is located has been peaceful for a long time, and he has never seen such a military disaster. It is only now that I know that this scourge of swords and soldiers is really the most tragic thing in the world. ”

Du Yu heard Wu Weiyi mention his hometown, so he slowly turned around, looked at Wu Weiyi, and said to him softly:

"This palace is really envious of Mr. Wu's homeland, since the beginning of the palace records, my father has led troops to fight with Ba and Qin all the year round, and Shu is the weakest among the three kingdoms, so Ba Guo has united the garrison of Qin in the area of Nanzheng with wealth, and tried in vain to annex my Shu in one fell swoop. The father of the palace and Du Jiang's father and two brothers joined forces, but with the contemptible division of Shu at that time, they broke through more than ten formations of the Baqin coalition army, and since then Ba has never dared to watch Shu again...... However, because the queen mother was worried about her father's safety, she was frightened and depressed in the palace for many days, and finally became ill and could not afford to get sick. Before she died, she wrote a trustee to transfer it to her father, hoping to bring back her father to see her for the last time, but in the end, she couldn't do it. When the war was settled and his father returned victorious, he learned the news of the death of his mother and his uncle, so he couldn't help but be very sad. So I decided to abandon the sword soldiers from now on, and to benevolently govern the people of the sea, hoping to comfort the souls of my mother and uncle in heaven. ”

The princess paused, then turned her head to look at the scattered remains of the Shu master under the hillside, and sighed:

"Hey...... Mr. Wu, why do you say there is always such a war in this world? ...... The little girl really doesn't know, how can we truly realize Mr. Wu's so-called 'the best and great harmony in the world, benevolence, righteousness and love'? ”

Hearing the princess ask like this, Wu Weiyi couldn't answer for a while. He asked himself, now his hands are also stained with the blood of thousands of Shu people, although he is really helpless. But if you think about it carefully, what is the difference between what he did today and the "human slaughter" that killed 400,000 Zhao people in the future? In this case, what qualifications does he have to talk about "benevolence, righteousness and love"?

Thinking of this, Wu Weiyi just kept standing beside Du Yu, lowered his head and pondered for a long time, but he didn't say a word. Du Yu saw that Wu Weiyi was silent now, but it was inconvenient for Mr. Wu to say more, so he raised the Qiang flute again and played the Qiang flute melodiously.

Not long after, I saw Wu Weiyi suddenly raise his head, as if he had thought of something. Then he went down the hill and ran down the slope. Then he searched the bodies of the remains of Shu soldiers everywhere.

The princess couldn't help but feel strange when she saw this, so she stopped the sound of the flute, and followed Wu Weiyi down the hill and asked:

"Mr. Wu, what do you mean by this? Why do you want to collect the relics of these Shu soldiers? ”

Wu Weiyi continued to search back and forth while explaining:

"War, throughout the ages, is a matter of life and death. However, people are not plants and trees, who can be ruthless. Once you are uprooted from Rong and Xiongguan, and you don't know if you can go back alive and well, who can really be fearless? Therefore, I guess these people must have brought with them all the things they hold most dear! ”

When Du Yu heard this, he became even more frightened:

Mr. Wu...... The so-called dead are great, how can you ......"

When Wu Weiyi heard this, he knew that Du Yu had misunderstood him, thinking that he was looting the belongings that these fallen soldiers were carrying, but he couldn't help but laugh out loud:

"The princess is misunderstood...... Who does the princess think she is? How could I do such a perverse thing...... I thought that I would collect all these objects so that I could return them to my relatives when I re-entered the city one day. Such...... It's a wish of these fallen soldiers. ”

When Du Yu heard this, his heart was immediately relieved. Seeing that Wu Weiyi was still busy back and forth, he couldn't help but have a trace of indescribable feelings in his heart. She didn't know herself, but this feeling was grateful. Or is it admiration? Du Yu didn't know how to speak at this time, just learning from Wu Weiyi, and he was also collecting it everywhere, completely ignoring the mud and dust here.

I saw Du Yu, her graceful and luxurious brocade curved deep robe and her fair and slightly red face were just a short time away, and they were already covered with mud and dust. Seeing this, Wu Weiyi smiled and said to the princess:

"The princess can do such benevolent things with her body of ten thousand gold, if she can preside over Shu in the future, it will be a blessing for the people of Shu."

As a princess, Du Yu can be said to have grown up in sugar and honey since she was a child, and the slaves and teachers who served around her, whether sincere or false, would praise her without hesitation. Therefore, Du Yu has been accustomed to hearing these beautiful words since he was a child, but he will never take these words seriously. On the contrary, there may be a natural aversion to those who like to flattery. But now Wu Weiyi's praise makes Du Yu feel extremely useful, and there seems to be a warm current in his heart. I saw Du Yu's face flushed slightly, and he smiled at Wu Weiyi, only to hear her whisper softly Mr. Wu replied:

"Huh...... Mr. Wu, you have praised it falsely. ”
