Inside Luoyang City.

There was basically no one on the streets. Most of the shops are closed. Only the pharmacy is still open. But a large number of doctors were drafted to the front. There are still a large number of injuries and illnesses outside the pharmacy, as well as various patients waiting to be treated.

Luoyang City lost his original vitality.

Cao Cao was bold because he had an official status. Dong Zhuojun soldiers, no matter what. Maybe it's to appease, or maybe it's not to expand the greater hostility. Dong Zhuo said that Cao Cao could be promoted to an official position. But Cao Cao refused. Dong Zhuo did not continue to investigate. But most of his infantry battalion was wiped out. Only a small part of the engineering corps remained, and they had already been demobilized back to their homeland. Cao Cao didn't want more people to get involved.

Among the fallen soldiers were several IRA adviser officers. Dong Zhuo didn't dare to offend, so for those who died in battle, the bodies of those who died were buried in good life. The IRA has sent personnel to retrieve the bodies of those who were killed. Maybe it's because of the Republican Army. Everything became so easy to solve.

Cao Cao, who lost the army, was not happy at all.

Cao Cao looked at the situation of many Dong Zhuojun soldiers. There were not too many wounded soldiers, and there were very few injuries, which shows that the battle was not very intense. But the number of sick people is very large, and the number is frightening.

By letter. Cao Cao already knew one of the major drawbacks of trench warfare. Epidemic diseases hurt soldiers far more than the enemy, and if such a problem were not heeded in the confrontation, the result would be a loss of one-third of the non-combat attrition, which could lead to a further deterioration of the situation if not kept under control.

Seeing the situation of Dong Zhuo's officers and soldiers, Cao Cao knew that Dong Zhuojun was extremely inappropriate in dealing with such a situation. Even in many places, it is very bad. Those sick soldiers defecated in the open. This can exacerbate the spread of the disease. Poor sanitation has become the worst enemy.

"Huh." Cao Cao sneered, he felt that it must be these epidemic diseases that defeated Dong Zhuojun. But he shook his head sadly. The people around him thought that Cao Cao was an extremely strange person, and there was no way, because this person always made some strange movements.

"It's really sad to attribute victory to epidemic disease and defeat the other side by disease." Cao Cao said.

Yes, the imperial court did not have any strength to fight against Dong Zhuo, but it hoped that a large-scale epidemic could defeat the other party, which was simply unbelievable to them. Faced with such a thing, they themselves don't know what to do.

On the castle tower. Dong Zhuo took the binoculars and looked at the battle line in the distance. Although it is not clear what is happening on the other side. But Dong Zhuo still hopes to see something, so that he can do a lot of beneficial things.

"This Lu Bu, will you cast it?" Dong Zhuo put down the binoculars and asked Li Dao.

"My lord, I will." Li Wei replied.

"Oh, why?" Dong Zhuo asked.

"My lord, even if Lu Bu doesn't take refuge in him, his subordinates will also take refuge in him, which will force Lu Bu to take refuge. The key is Lu Bu himself. Many of Ding Yuan's practices have been unable to get Lu Bu's support. The lord gave him the position of the lieutenant general. Li Dao said.

"It's good for this person to be greedy." Dong Zhuo said with a smile. Yes, Lu Bu will be greedy for these power, money, beauty, these things are good, and those of his subordinates. What happened to me on my side, the same is true for that side. They may not be in a better position than they are here. In this way, Lu Bu was forced to make some choices.

However, Dong Zhuo was still more worried, he was worried that Lu Bu would not be able to succeed and still get nothing in the end, which was a big, big problem for him. But now there is no way to worry.

Republican Army, Lijiazhuang.

Inside the Institute of Science and Technology.

"These science and technology research institutes must ensure their safety." Shang Wu said that Shang Wu and Jia Xu came here many times to visit because many useful technological inventions were concentrated here.

But as the institute of science and technology continued to grow, it grew in size, and the area was densely populated. The security situation of protection is getting higher and higher, and of course it is getting more and more difficult. The Republican Army needed to mobilize an infantry division to protect it. But this is a burden, the current strength of the Republican Army is not too rich, and they still need to draw troops in many places to properly solve some of these things. How to fix it. It's going to be extremely difficult.

"We're already doing that. The focus has shifted to various parts of Luzhou, where there are mountainous areas that can provide good shelter. For transportation, though, there are some difficulties. Jia Xu said.

"As long as we provide sufficient material guarantees, we still have to overcome many difficulties." Shang Wu said helplessly. In order to ensure the Republican Army's scientific research and technology, as well as to allocate some mobile troops to reduce the pressure on defense, Lijiazhuang is located in a plain area, which is very easy to be attacked, and it is extremely difficult to defend. Once this happens, it can be extremely chaotic and difficult for anyone to deal with.

"I understand." Jia Xu nodded in agreement with such a point. Jia Xu also attaches great importance to technology, because he has seen many new developments brought about by technology.

For example, the development of electricity. Generators, as well as electric motors, have appeared in the Republican Army laboratory, but only in an experimental nature, in the past they only made batteries to generate electricity. But now, they have the ability to generate electricity, which is an amazing invention.

In addition to this, there is a new invention. Camera.

The progress of chemistry provided the Republican Army with the ability to invent film, and of course, Shangwu also brought a lot of knowledge of black technology, and the periodic table of chemical elements was regarded as an absolute secret archive, and only high-level chemical researchers could access this absolute secret.

Film was invented using various techniques, but the camera was still an early camera, and if you wanted to take a picture, you had to stay in front of the camera for half a day. The definition of the photo is not very high, and some places will be affected by the light factor, and it will come out very blurry.

After Jia Xu saw such an invention, he was quite amazed, he didn't know what the principle was, but it was enough to show the importance of technology.

But the camera remained in the laboratory stage, and Shang Wu invented the camera, and the role of film, in order to provide better aerial reconnaissance. If you use this camera technology, you can greatly expand the intelligence of the Republican Army. The emergence of generators and electric motors is to lay a better foundation for the Republican Army to enter the wireless era.

Because the cable telegraph is extremely unfavorable for air operations. There are too many constraints, so they are not too meaningful, and they still seem extremely clunky.

Of course, there are many black technologies that are also being actively studied, such as internal combustion engines.

This was a new technology, but the internal combustion engine was only just beginning to use refined oil, and before Shang Wu offered advice, some young researchers in the IRA felt that propulsion of turbines through steam was very slow and cumbersome, and the steam engine was still cumbersome and consumed coal. greatly restricts the load, as well as his effective power.

They desperately wanted a lighter machine to appear. By studying the steam engine, they discovered the importance of pistons. In turn, they want a fuel that burns quickly and can provide continuous power.

The idea is correct, but the first thing they think of is **. Yes, very crazy idea. They tried many times, and many times were unsuccessful.

If Shang Wu doesn't provide advice, the IRA will probably waste more time on the fulcrum of the tech tree. They modify the scheme, not the fuel. Because they think that ** is the best thing, the heat provided in an instant is great, but the disadvantages are also obvious, it is not easy to control, and even, sometimes the piston itself becomes a kind of artillery. And then there's the residue. This can be a serious failure.

But that's it, the scientific and technological researchers of the Republican Army are conducting research with great enthusiasm.

There are many similar projects underway. At the same time, some projects have been improved, for example, telephone. This could greatly expand the IRA's communications capabilities. Before, the phone lacked great utility, but it was studied in a scientific laboratory. The phone will inevitably go to the military.

However, the distance of telephone communication is still limited and cannot be too far, but this is enough for battlefield communication and to maintain coordination between artillery and infantry.

This is a kind of black technology, without such a black technology, it is absolutely impossible to think of such a state of action.

Jia Xu is also actively changing some of his views on technology, for example, in the past, it took a lot of resources to do the effects that could not be achieved by manpower. Even, more sacrifices have to be made. But technological changes, for example, the emergence of crane machinery, can greatly reduce the demand for labor, with machinery, with fewer people can do more and more things, this is a great effect of the improvement, in such a state, many things have become easier.

This is a big improvement, which means that the IRA will be supported more powerfully, and the attrition of the other side will become more severe. These are all advantages that come with technology.

The IRA can do many, many things that others dare not do. This advantage is at the crushing level.
