"Toilets must be clean and tidy, even in war." Shang Wen said sternly. The first thing Shang Wen did when he arrived in the north was to inspect. Then make corrections one by one.

"What. Toilets to be clean? Meng Tian felt a little funny.

"There's nothing funny about that." Shang Wen said solemnly.

"Is there anyone in your army who vomits and diarrhea?" Shang Wen asked solemnly.

"yes. How do you know? Meng Tian asked in surprise.

"Just look at the very bad facilities in the military." Shang Wen covered his nose and said.

"The toilet should be a wooden room, with a car inside and a lid on top. Place a bucket or other container under the vehicle, and concentrate the excrement in general. Then clean up regularly. Use diesel, or gasoline, to incinerate the excrement. Hurry up and do it. Shang Wen ordered.

"Do as your lord says." Meng Tian commanded.

"Whoa." The guard said.

"Such toilets have to be one for every 500 people. No other people can live around. Shang Wen emphasized.

"And I need a blueprint of the base, the whole base facility is just terrible." Shang Wen said.

"Base?" Meng Tian asked.

"It's our camp." Shangwen explained.

"Also, those who live in tents can move to shacks for you. However, it is necessary to pay attention to ventilation. Shang Wen said.

"The facilities inside can be processed with wooden boards. Soldiers can sleep more comfortably. Shang Wen said.

"But I'm not afraid they'll die like that." Meng Tian said with some concern.

"No, no. Here's what you're talking about. It was windy that day. You only have one vent. Strong winds make it impossible for air to circulate in the ventilation ducts. And then you actually heat up indoors. As a result, the combustion is not sufficient, so a large amount of carbon monoxide is produced. Carbon monoxide is colorless and odorless. It is an invisible gas. I can burn. Poisonous. So, this is the reason why your soldiers are dying in large numbers. Shang Wen said.

"Just improve the ventilation duct. That's it. The rest is nothing to worry about. Shang Wen said.

"Oh." Meng Tian agreed.

"And the patients. All of them should be taken care of intensively. And to put masks on them. Otherwise, one infects two. Two infect four. When the time comes, we won't have to fight. Shang Wen said.

"And the officers, who have to check the soldiers' socks and shoes every other hour. to prevent frostbite from appearing. There is also trench disease. Shang Wen said as he examined.

"That's a lot." Meng Tian said.

"The military facilities are very backward." Shang Wen said.

"The army is so unusual. The place is just too narrow. The living conditions are very poor. These roads should be hardened. There are no drainage facilities. You should build a road as if you were building a road, and then build gutters on both sides of the road. This way the road surface will not be as ditched as it is now. There's not even a place to put your feet on. Oh, my God. Too bad. Shang Wen complained a little.

"Oops. You've just been so angry. Meng Tian said.

"It's not that I'm angry, it's that your military facilities are too imperfect." Shang Wen said.

"It's not clean at all in the barracks. Especially the toilets, now your army is plagued by severe dysentery, epidemic diseases, frostbite. In less than half a month, this army of tens of thousands of people will all become a sick army. The Yueshi people can send us back to Xianyang without a war. Shang Wen said solemnly.

"These things must be handled as soon as possible. It is best to do it within a day, especially for those with medical conditions. It has to be so centralized. Shang Wen said.

"By the way, if you still have some fever symptoms, you must seek medical attention as soon as possible. None of the officers could conceal it and report it. Shang Wen said.

"Okay." Meng Tian agreed.

"And defenses. Our defense is a simple line, and it will not work without defense in depth. Shang Wen said standing on a high platform.

"Defense in depth?" Meng Tian said.

"Yes. It is to lay out the line of defense one by one. After we kill in the first line, we slowly retreat, so that we can kill the enemy in batches. If you want to do this, you have to dig a lot of trenches and lay out a lot of barbed wire. Build bunkers, bunkers, put those cannons. Shang Wen said.

"Okay, I'll do it." Meng Tian said.

"Wait, I've got some tools. Send them all. Shang Wen said.

Meng Tian quickly explained. Shang Wen also used his binoculars to check the defensive ring of the camp.

"That's pretty much it. The patients took me to see it. Shang Wen said.

"But before we do that, we have to wear masks." Shang Wen said and took Meng Tian to the large number of supplies he brought.

"How?" Meng Tian asked.

"It's not going to be good." Shang Wen said.

"You. Come here. Shang Wen pointed to a physician and said.

"Tell your head at once and let him separate the patient. Severe and mild are all separated. Also pay attention to disinfection. Shang Wen said.

"Disinfection?" The doctor asked.

"Oh, just with vinegar, a lot of spraying. Here, too, all the barracks. It must be sprayed in its entirety. Shang Wen said.

"It's too much." Meng Tian whispered.

"In addition, gather a group of sergeants and teach the patients common sense, so that they can check the patients on the battlefield at any time. All that can't be solved is sent here. Shang Wen said.

"Whoa." The doctor immediately agreed.

"It's a simple battlefield rescue system. A field hospital is set up in the rear, and medical nurses are set up on the front line to carry out simple treatment, and then be transferred to the field hospital for treatment. In the end, it was really not possible to transfer it to the rear for treatment. Shang Wen explained.

"Oh." Meng Tian agreed.

"That's right. What did you do with those corpses? Shang Wen remembered suddenly. The most difficult problem is these corpses.

"Buried." Meng Tian said.

"Buried. Without the tools I gave you, you wouldn't have been able to dig that deep, and even if you had, you wouldn't have been able to bury it deeply. And. Never mind. Have you sprinkled lime powder? Shang Wen said.

"Lime powder. What are you doing with this? Meng Tian asked.

"Prevent secondary bacterial infection." Shangwen explained.

"It has to be dug up. Then pour gasoline or diesel fuel and incinerate it all. I know it's a difficult decision to make. But for the safety of all, there is still this war that can be fought. We have to do it. Shang Wen knew what this decision meant. A lot of soldiers couldn't understand it. Especially the friendship formed in the special environment of the battlefield. But this is war, and it has to be done.
