At the beginning of September, the weather gradually cooled.

Yang Chengying added a large piece of armor outside, and under the protection of the guards and reconnaissance company, he went deep into the mountainous areas of eastern Liaodong.

An official road about five meters wide zigzags through the mountains.

From west to east, the stone gate is closed, the upper Hata pier, a large piece of ridge pier and so on are strung together, and to the south is the embroidered rock city.

That's where the Tiangong Bureau is located.

The second quarter of the first month of the unitary month is equivalent to half past five in the afternoon of modern time.

A detachment of cavalry appeared at the end of the road.

Ahead is Embroidered Rock Castle.

Suddenly, Zu Zehong raised his hand and pointed forward:

"Jinglu, you see, Lord Song and the technicians are lined up to welcome you."

"It's finally here."

Yang Chengying let out a sigh of relief.

The wagons for carrying supplies had pack horses that could be replaced, but he did not.

In order to save the horse's leg strength, he often dismounted and led the horse for a while.

"Jinglu, you should feed a few more war horses on a few piers."

Ning Wan led the horse behind, his face full of exhaustion.

"Mr. Ning doesn't know, even if there is a war horse, it can't be fed."

Jin Shenghuan said with a smile: "From Gaizhou to the east, there is no good pasture along the way, and it is okay to feed pack horses, but it is difficult to feed war horses." ”

A fat and strong war horse is very laborious to raise.

Male and female selection, breeding, forage supply, veterinarians, etc., are very demanding.

"No wonder Jingluo wants to change horses in Gaizhou and ride a bad horse to embroider rock city."

Ning Wan suddenly realized.

"Don't mention it, it's sad to talk too much."

Yang Chengying sighed.

The northeast was not fully developed at this time, and it was the Xiaoice period.

The forest is dense, and a careless one can cause a fire.

If it weren't for the fact that there were only tungsten mines in Xiuyan City in the entire Northeast, he would never have invested such a large amount of manpower and financial resources.

As he spoke, he approached the welcoming crowd.

Song Yingxing said: "The subordinates led the staff of the Tiangong Bureau to meet the scripture. ”

Yang Chengying replied: "Mr. Song, don't come unharmed." ”

"Everything's fine." Song Yingxing replied with a smile.

Yang Chengying bowed to Wang Tianxiang and other technicians again, and walked into Xiuyan City.

Xiuyan Castle is very different from the past, the fortress has been expanded several times, and the scale is three times larger than before.

It is four miles long from north to south and three miles wide from east to west. There are four city gates, the north gate is connected to the large ridge pier, to the west to the tungsten mine, to the east is the opposite bank of the river, is the farming area; To the south, the terrain is open and undeveloped.

There are 1,350 households in the city, with 23,518 people, almost all of whom are the families of the Tiangong Bureau and the families of soldiers.

There are 18 smelting furnaces, 6 roasting furnaces and 3 coal mine warehouses in the city......

In short, it is already a smelting city with highly complementary technologies.

When Yang Chengying entered the city, he only saw Huang Yao: "General Huang, where is General Xiang?" ”

"Back to Jingluo, General Xiang goes out to patrol the sentry, the more you have to be careful at this time."

Huang Yao replied with a fist.

With Ma Santai being awarded the medal and the Tiangong Bureau being included in the name of the Academy of Science and Technology, Xiuyan City has been exposed.

Just in case, Zhang Hongmo, the commander of the Yongjian Battalion, sent Xiang Zuolin, the first sentinel commander, to guard Xiuyan City and protect the Tiangong Bureau with the guard Huang Yao.

"It's good to be careful, wait for him to come back and give this to him."

Yang Chengying took out a lump of meat from the pocket on the horse's back, which was rabbit meat.

"Subordinate General Xiang, thank you for the grace of Jinglu."

Huang Yao took it with both hands.

Yang Chengying and Ning Wan and others entered the city smoothly.

The city had already set up a place for them to stay.

After taking a shower, Yang Chengying changed into clean clothes and met Song Yingxing again.

Song Yingxing carried a saber and a flintlock pistol.

Yang Chengying picked up the flintlock pistol and looked at it carefully in the sun.

Song Yingxing said with a smile: "After a while, my subordinates used their own modified pedal lathes to produce hammers, fixtures and other components, which made the flintlock pistol more precise and easier to fire." ”

"Sure enough, it's a genius production!"

Yang Chengying played for a moment, and couldn't help but admire.

As a top student in a military academy, quick disassembly of firearms is a basic operation.

However, modern firearms are too sophisticated.

Even if Yang Chengying wanted to, with the situation at the time, he couldn't achieve it.

Now with a foot-operated lathe, it's time to move on to the next step.

"Sir, how many technicians are there to learn from you?"

Yang Chengying asked.

"Including the one sent by the Knowledge Academy, the three ordnance bureaus add up to a total of more than a thousand people."

Song Yingxing replied.

"Are they all proficient in lathes?"

"Reluctantly, there are some attitudes that are very stubborn, and being reprimanded by Mr. Mao and Mr. Sun has changed a lot."

"Wang Tianxiang and the others, how do you grasp it?"

"Naturally, they are skilled and are starting to think about how to use water to make lathes more convenient."

Hearing this, Yang Chengying nodded with satisfaction.

The next step is to use this lathe to make precision metal screws of any pitch.

Then use screws to make a more perfect lathe.

If you are proficient in the lathe, you can make a boring machine.

By the time they had become proficient in making artillery with boring machines, a great invention was in sight.

Feeling excited to think about it, Yang Chengying suppressed his excitement and gently put the flintlock pistol on the table.

At this time, the utensils used to cook the sake gurgled and bubbled.

Song Yingxing got up, took a towel and grabbed the handle, and was about to pour wine.

Yang Chengying stopped: "Mr. Song, please wait a minute." ”

"How?"

Song Yingxing looked surprised.

"Mr. Song, let me ask you, is this wine cooking vessel powerful?"

Yang Chengying pointed to the white vessel and asked with a smile.

"Force? How can this be powerful? Song Yingxing said with a smile.

"Then you hold the lid and feel it."

Yang Chengying took the towel in Song Yingxing's hand and put it on the lid.

Song Yingxing looked puzzled and pressed the lid with his hand.

Grunt...... Grunt......

Under the pressure exerted by Song Yingxing, the lid was pushed up desperately, and the white gas was desperately rising.

Song Yingxing was afraid of exploding, so he quickly let go of his hand.

The moment he let go, the lid flew out.

Thanks to Yang Chengying's quick reaction, his body tilted and dodged the lid that flew out.

The lid slammed against the wall with a bang, fell to the ground, and clanged a few times before it quieted down.

Song Yingxing's face was palpitating.

If you hit the strategy, it will be a big problem.

Yang Chengying laughed: "Sir, look, is this force!" ”

Song Yingxing nodded silently, still not possessing his body.

"You said that Wang Tianxiang wanted to use water instead of pedals to push the lathe. This shows that water is also force, just like the force of burning coal can melt iron. ”

Yang Chengying patiently guided: "If you think about it carefully, I use firewood for soju, what if I replace it with coal, and it is a lot of coal?" ”

"That would be very powerful." Song Yingxing reacted.

"Not bad! What happens if we use this force on the car and push it forward? ”

Yang Chengying continued to guide.

"That's the power to change the whole world!"

Song Yingxing looked frightened, but said with great certainty.
