"Is this important?" Xiao Yu asked casually, and Cai Jing's heart instantly tightened...... He secretly scolded himself, he was still too anxious, but there was another voice in his heart eagerly looking forward to it, he needed a shortcut to climb up to the south, if he could climb the high branches of King Yan, then he would have a bright future...... Cai Jing held his breath and stared, not even daring to speak, for fear that his heart would jump out.

Xiao Yu didn't let Cai Jing get entangled for too long, otherwise this big traitor would have failed to succeed.

"Well, I'll admit it, he's my daddy!"

"Ahh Seriously? Cai Jing blurted out, he couldn't wait to give himself a mouth, what nonsense!

The corners of Xiao Yu's mouth twitched twice, and he said helplessly: "It's nothing good to recognize my father indiscriminately...... Look, I don't know if I care about you or your father! ”

Very disappointed, Xiao Yu shook his head, he was about to leave, Cai Jing was even more panicked, if he lost this opportunity because of his recklessness, he was afraid that he would regret it for the rest of his life!

Cai Jing rushed out and stopped in front of Xiao Yu.

Xiao Yu's face was gloomy, "Cai Shuban, I have already answered your question, please go and do things, and please keep it a secret!" ”

"Wait...... I, I said that I want to invite you to eat roast lamb legs, and also, please also invite the king, the king to appreciate the light! ”

Xiao Yu hesitated for a moment, and his face finally turned cloudy, this Cai Jing is still a bit of a brain, not confused!

"Now we have to march, let's wait until we get to Wild Fox Ridge!"

Cai Jing immediately agreed, his tone full of joy.

"Yes!"

……

After a short camp, the Song army continued on its way.

During this day, the Song army encountered at least three Khitan scouts, and the two sides fought, and 7 Song soldiers were wounded...... Zhang Qi sent them all to the side of the convoy, hoping to free up some places.

Xiao Yu generously took them in, and along the way, a lot of coal had been burned on the car, and the empty place was just for the wounded...... Xiao Yu was also calculating, this time to attack Yehuling, the distance is only 300 miles, if it is farther away, the coal carried may not be enough, and there must be a supply station on the way.

Therefore, things like machinery cannot only see the benefits, but also focus on the huge consumption.

This way is not only coal, but also parts, including eucommia rubber tires, also damaged a lot, Dad mentioned that the more suitable for making tires should be rubber trees, but at the moment Da Song has not, is sending people overseas to look for ...... The ghost knows what Da Song doesn't have, how did Dad know, and he named it!

Xiao Yu is too lazy to investigate, he just wants to write down what he observes, these first-hand information is related to the development of the tractor industry, and may also be related to the combat methods of the Great Song Dynasty, so he can't be cautious.

To Xiao Yu's surprise, Cai Jing was also doing the same thing, and he remembered it in much more detail than Xiao Yu, he not only wrote down the consumption of coal, but also the amount of water.

Moreover, in winter, the water of the boiler will freeze when camping, and it needs to be preheated again, and the time consumed in the middle is very large, at least half an hour...... In the case of a short break, he believes that the boiler should not be stopped and that combustion should be kept to a minimum...... Although this will increase the consumption of coal, it can ensure a quick response and will not be attacked by the enemy! ”

"That's good!"

Xiao Yu smiled, "It's very detailed, and the handwriting is beautiful." ”

A casual compliment made Cai Jing overjoyed and worked harder.

At dusk on the third day of their trip, they finally approached the Wild Fox Ridge as they wished, and 20 miles away, there was the castle under the Wild Fox Ridge - Wusha Castle!

At this time, the convoy had already walked to the front of the whole army, and Zhang Qi was 10 miles away from them...... Xiao Yu was full of relief, those elm heads holding the war horse were convinced this time!

If it weren't for them to drag them down, the convoy would have been able to run faster, maybe in a little more than a day.

Sure enough, flesh and blood are not as good as machines, if one day, soldiers and supplies can get on the car, what riding and shooting is unparalleled, what grassland is vast, it's all a fart!

By the way, Dad once mentioned that if the tractor is more powerful, and the iron armor is put on the outside, and then the fire gun and artillery are added, then it is the real king of land warfare, and the iron horse is invincible!

Maybe I can study in this direction in the future, and try it when I get back......

Xiao Yu was waiting for Zhang Ji to arrive, and suddenly above the snow field, a jumping black spot appeared.

"It's a Khitan!"

Through the binoculars, it was possible to count that there were almost 50 people on the opposite side, which was a standard scout team!

Xiao Yu immediately jumped up, "Everyone form a formation, prepare to fight!" ”

These drivers and coal shovelers have been trained, in the face of the enemy, not to panic, Zhang Qi also gave Xiao Yu 20 people, they were immediately ready for battle, but in comparison, no one is as good as Cai Jing, this one is standing on Xiao Yu's side, ready to block his gun at any time!

It's really flattering, but at this juncture, blaming a person who is willing to give you his life is a fool's business!

Finally, the person on the other side was getting closer and closer.

In fact, the Khitans don't need to get so close, but a group of people suddenly appeared here, and the thing behind them looked like a car, but it was extremely large, and what was even more surprising was that there were no horses, and they were spitting black smoke.

Boy, what kind of monster is this?

Curiosity made the Khitans forget their fears, and they desperately approached to find out!

"Shoot!"

With the sound of gunfire, a row of Khitan soldiers fell neatly, faster than the wheat was harvested.

The remnants immediately panicked, and the second round of shooting arrived, and the Khitan soldiers turned on their backs, and there were less than ten people left, and they panicked, turned their horses' heads and were about to run.

Of course, Xiao Yu wants to pursue, but the cavalry has not yet arrived, what should I do?

Just when Xiao Yu was running out of ideas, suddenly in his team, a tractor started, the high ball clutched the joystick, and his eyes were glowing feverishly!

"Rush!"

The tractor rode into the dust and chased down the Khitan cavalry.

Just above the tractor, Tong Guan pursed his lips and held a firearm in his hand...... This is the latest firearm developed by the Great Song Dynasty, which is not only a rear-loading gun, but also rifling.

Because it is a new product, the cost is high, and only the transport team with the responsibility of protection can have such luxurious equipment!

Tong Guan aimed the gap at the head of a cavalryman!

Bang!

A ball of blood exploded in the opponent's chest, which was extraordinarily gorgeous!

Tong Guan's hand shook, and then he quickly loaded and aimed at another person, and the gunfire rang out again, and the other party was shot and wounded, and rolled off the war horse. Shoot twice in a row and kill two enemies in a row!

Tong Guan's actions made everyone wake up like a dream!

That's right!

We're not just convoys, we have weapons, we have tractors!

"Chase!"

Xiao Yu was the first to jump on a tractor.

Everyone was moving forward at full speed, and at this time the sun was almost setting, and their tractor was like a monster running out of the shadows, making a huge roar, spitting black smoke, and the earth trembled.

It's a monster!

The remaining Khitan scouts, with only one thought left in their heads, the gunfire became more and more intense, and one by one they fell, and the last Khitan scout fell violently, one of his arms was broken, and blood gushed out.

He only had one breath left, and looked blankly, in the mouths of those monsters, there were Song people's faces, and on the monsters' bodies, Song people were standing......

"Is this the Heavenly Soldier?"

The Khitan scout died, he died not under the fire, nor from the cold, but from fear!

Scared to death!

Goball looked at the corpse on the ground and cheered.

"Hahaha, Lao Tzu has made meritorious contributions, Lao Tzu killed the Khitan dog!"

Above his head, there was a Tong Guan's ruthless voice.

"I killed him!"

Gaoqiu was not convinced, "Without me driving, can you catch up?" Otherwise, you drive and I'll shoot, how about it? ”

Tong Guan was stunned for a moment, and then shrugged his shoulders.

"Whatever, if you can find the Khitans, I'll listen to you!"

"I'll find a head!"

Gaoqiu blew up his lungs, Xiao Yu chased after them, saw them, and immediately said, "What are you doing stupidly, go to Wusha Castle!" ”

"We? Usha Castle? ”

There are not enough highball heads, just rely on them, and there are no weapons to attack the fortifications, and the number of people is so small, what's the use?

At this time, from the side of the driver's seat, Cai Jing stood up and said eagerly: "The Khitan dog thieves were stupid by us, so at this time, clean them up, like picking up things!" ”

This sentence finally reminded everyone, and everyone immediately boiled with enthusiasm, and rushed towards Wusha Castle!

……

"General Qiyu, the convoy is in front, only 5 miles!"

Zhang Qi's face was dark, grandma's, what the little ancestor said sounded good, but in the end he ran to the front, if he met the Khitan brigade, what would he do?

He could only pursue it vigorously, and when he reached the place where the convoy was resting, not a single tractor was gone.

Zhang Qi felt that his heart had been taken out!

"Where are they, people?"

He was screaming like crazy, and suddenly a scout came to report.

"General, don't worry, the convoy is going to attack the city!"

Burst!

Zhang Qi vomited blood, please, you are a transport team, not a death squad, and it is not your turn to attack the city!

Besides, there are only a few of you, there are no gunners, and there are no ladders, how can you attack the city?

Along the way, Lao Tzu was worried that the Khitans would suddenly come out, but the result was good, if people didn't come, you would bump into it yourself! I'm just impatient!

Wang Zongxuan, don't think that you are the son of King Yan, I can't do anything about you, I'll tell Zihou when I go back, let him go to Shiniang, and see if the princess punishes you? ”

Zhang Qi couldn't wait to put Xiao Yu at the mercy of eighteen appearances, but he just thought about it!

"Quick, come with me to Usha Castle!"

When Zhang Qi panted and appeared outside Wusha Castle, the castle was quiet.

Suddenly, the city gate opened, Tong Guan and Gaoqiu stood on the left and right, and couldn't hide their joy and said: "The last general has taken Wusha Castle, please enter the city!" ”

With that, the two of them turned around and walked inside...... Zhang Qi was stupid, so he took it down, I heard that there were hundreds of people in the castle! It's not a good stubble!

He was suspicious and led his men into Usha Castle, and he was dumbfounded when he entered...... The black was oppressive, and the Khitans knelt all over the ground, and they didn't even have the courage to raise their heads...... Xiao Yu and Cai Jing are looking at the captives with satisfaction!
