Everyone followed up to the Ministry of Industry, and the excavator was developed at this time.

Lu Bu has basically all kinds of viewing, tracks, buckets, and control rods.

Although it is not comparable to excavators in later generations, it is indeed the first heavy machinery.

"Maybe digging?" Lu Bu asked.

The manager said: "When I returned to the temperature, I could dig the soil normally. However, the hydraulic system mentioned in the temperature has not been successfully developed. If I use such an excavator to dig the soil, it can only be about ten times the manpower. The coal consumed is far more than manpower."

Lu Bu nodded, he knew he couldn't hurry.

Although he has explained the principles and manufacturing processes of the hydraulic system, it will be of no effect without appropriate sealing technology and hydraulic oil.

The process can only improve a little bit.

"I understand, let's build five hundred such excavators first."

"Five...500 vehicles!" The manager was shocked on the spot.

"What, there is a problem?"

The manager had to say: "When we returned to the temperature, the current steel resources were preferred over military factories, followed by agricultural tools, and finally tools. Excavators needed a large amount of steel. If they were manufactured in large quantities, our iron ore resources would not be able to keep up."

Lu Bu took a deep breath and felt uncomfortable again.

Although his smelting technology has been greatly improved, he cannot dig more iron ore, which is equal to zero.

In order to conquer the world and to have sufficient military reserves, Lu Bu asked the military factory to continuously produce various weapons.

With the improvement of various equipment, the resources required by military factories have also been greatly improved.

Digging iron ore, coal mines and other various mines requires people.

Mining requires people, factories require people, farming requires people, building houses requires people, and doing everything. Lu Bu deeply feels that there is too little manpower.

Because his heart was too big, he didn't want to slow down.

Even an excavator could not be built, so he still talked about how to build a railway, etc.

The steel resources needed were simply countless.

Lu Bu sighed: "Let's build it with the only resources. I will study it with you during this period and strive to improve performance again."

"Thank you, Wen Hou!" The manager was overjoyed. With Lu Bu, all kinds of research were simply rocket-like improvements.

Every time Lu Bu comes, he can solve the problem easily and easily.

Lu Bu returned home first to explain some things, and then prepared to stay in the Ministry of Industry for a while.

It was precisely because of checking various current situations that Lu Bu was very depressed.

Coupled with the dissatisfaction of the powerful men and the rejection of Kong Ming and others, Lu Buyu was unable to extricate his anger.

"Hmph, traitor, right?" Lu Bu couldn't help but snorted coldly. Pang Tong's words must be a polite version. What Zhuge Liang said is probably even more unpleasant.

Since that's the case, don't blame him for suppressing it.

Lu Bu knew very well that Zhuge Liang's ability was that one person could support a country's military and internal affairs.

According to reports, Zhuge Liang was 19 years old this year and had just moved to Nanyang. He was appointed as Sima Hui as his teacher.

Zhuge Liang has not yet married Huang Yueying, and Lu Bu's idea is to intercept the Hu.

Without Huang Yueying, Zhuge Liang's talent would have to drop by 30%, not only 30%.

According to the original history, Zhuge Liang came out to help Liu Bei in 207, when he was 27 years old.

History has changed now, and Lu Bu is not sure whether Zhuge Liang will come out in advance.

Lu Bu soon sent an envoy to Jingzhou to find Liu Biao.

Lu Bu believes that Liu Biao will never refuse his request.

After sending the envoy, Lu Bu went to the Ministry of Industry to develop various machines with peace of mind.

Hydraulic technology must be overcome, otherwise the efficiency will be too low. Not to mention reaching a thousand times the human power effect, it must have at least a hundred times the effect.

In this way, he was able to dig the entire canal within three years.

Because the canal he wants is wider and deeper, and it will exist for generations.

In addition, there are quarrying machines.

Without machine cutting, the stones picked will be difficult to level.

To do it, you must do your best.

In addition, gravel can also be used to pave roads and pave the way for future roads and railways.

The most important thing is to build oil production engines and create the era of internal combustion engines.

Lu Bu had too many things in his heart to create, but he also knew that he could not get faster with his own strength.

Everything can only be done slowly.

A few days later, the envoy of Lu Bu arrived in Xiangyang and met with Liu Biao.

After trying Tang Modao sent by Lu Bu, how could Liu Biao not be excited? You should know that this is not a magic weapon, but 50,000.

But this matter is very important, so Liu Biao naturally wanted to summon important officials under his command to discuss it together.

Similarly, Liu Biao Group also has two major factions.

Cai and Kuai.

Kuai Liang took the lead in speaking: "Lord, Liang thought this matter was feasible. As far as Liang knew, Cao Cao married three daughters, and then he obtained Lu Bu's troops to defeat Yuan Shao. Yuan Xi exchanged Zhen Mi for 30,000 Mo Dao and 30,000 war armor. Now what Lu Bu said about 50,000 Tang Dao will not be fake."

Liu Biao nodded and then looked at Cai Mao.

Cai Mao nodded immediately: "Yueying is also at the age of getting married. It is our benefit to be a good friend to Lu Bu. With these 50,000 soldiers, we are not afraid of Sun Ce and Cao Cao."

"Yes, yes, Lu Bu is not bordered by us, it is suitable for a distance and attacking nearby. This matter can be accomplished, please do not hesitate!" The other ministers agreed.

Because they really fell in love with Lu Bu's products, if they had a feud with Lu Bu and Lu Bu didn't sell these products to Jingzhou, they would be depressed.

Seeing that everyone agreed unanimously, Liu Biao nodded in agreement.

However, he still needs to discuss this with his wife.

Huang Chengyan has a high reputation, and it is still difficult to deal with without obtaining the other party's consent.

Soon, Liu Biao told Mrs. Cai about this matter and asked Mrs. Cai to help persuade Huang Chengyan.

For the sake of great cause, Mrs. Cai naturally wanted to help Liu Biao.

Moreover, with the addition of Lu Bu, there is great benefits to her Cai family, which is not unreasonable.

Mrs. Cai hurriedly promised: "Don't worry, husband, it's good to hand over this matter to me!"

Liu Biao nodded, giving full power to Mrs. Cai.

But seeing that Liu Biao was not very happy, Mrs. Cai couldn't help but ask: "Your husband doesn't seem to be happy?"

"Hey!" Liu Biao sighed: "In addition to marrying Yueying, Lu Bu also asked for someone from his husband."

"Oh? Who is it?"

"Huang Zhong!"

"Huang Zhong?" Mrs. Cai exclaimed: "This person is only a young general, so I gave it to you. Why is your husband not happy?"

Liu Biao shook his head: "Huang Zhong has extraordinary martial arts and is a great talent. Someone has recommended him to his husband several times."

Mrs. Cai was surprised: "Since that's the case, why don't your husband value this person?"

Liu Biao smiled bitterly: "Huang Zhong is a branch of the Huang clan and is incompatible with Huang Zu. With Huang Zu here, how can he use him for his husband? And many civil and military officials do not like Huang Zhong!"

"This!" Mrs. Cai instantly understood all the cause and effect.

Although Jingzhou is a brilliant place, it has many aristocratic families and the relationships between the various families are even more complicated.

Although Liu Biao was the leader of a state, he was unable to control all power at all.

This is also one of the reasons why he can only stick to it and cannot go to war.

After understanding the reason, Mrs. Cai smiled: "Since Huang Zhong has troubled her husband, I will simply give Lu Bu the value of 50,000 soldiers, which is far more valuable than Huang Zhong."

"Ha!" Liu Biao smiled bitterly again. How do women understand the importance of talents?

However, he didn't plan to change anything. All the ministers agreed with Lu Bu's request, so he couldn't change anything.

Soon, this incident spread to Huang Chengyan.

However, Huang Chengyan was furious.
