Not to mention the little devils, even the Tiger Ben soldiers lying in the trenches were deeply shocked by the scene in front of them! Even Ren Chao couldn't help but stick out his tongue, and couldn't help but wonder if it was too much explosives or a little too many grenades.

But Ren Chao was only slightly stunned, and soon returned to normal, "Huh! He drew his broadsword, stood up, and shouted, "Brothers! Kill me with me! As he shouted, he jumped out of the trench first.

"Kill!" Hearing Ren Chao's roar, the soldiers of the Tiger Army quickly woke up from their shock, picked up their rifles, hung their bayonets, and rushed out behind Ren Chao.

The people who had already been bombed turned over on their backs, and the little devils who were in a mess saw the tiger army pounce bravely, and they couldn't organize effective resistance at all, and many little devils subconsciously turned around and fled. Ren Chao led the soldiers of the Tiger Army to chase and kill hundreds of meters all the way, and the little devil he killed fell into the water and fled!

"Rejoice! Ha ha! Ren Chao looked at the back of the little ghosts and couldn't help but look up to the sky and smile.

"Lord Ren!" As soon as Ren Chao came back, Meng Yan, the head of the fourth regiment, surrounded him, Ren Chao smiled, "Did you see it, as soon as Lao Tzu made a move, he immediately beat the little devil to the ground." ”

"Yes, yes! Adults are wise and martial, and naturally they are extraordinary! Meng Yan saw that Ren Chao came back safely, a small heart was finally put in his stomach, and when he heard Ren Chao start to brag shamelessly, Meng Yan had no choice but to praise Ren Chao twice, "My lord, you have worked hard!" You see that now that the little devil has retired, you better go back and rest quickly! Hey! ”

"Look at your stupidity!" Ren Chao punched Meng Yan in the chest and scolded with a smile, Meng Yan's little thought naturally couldn't hide from Ren Chao, "Okay!" I'll leave it to you here, I'll go back first! Ren Chao said and turned around and strode away.

"Congratulations to Lord Ren!" Meng Yan and the others bowed one after another.

Ren Chao took the guard camp and returned to the Chinese army camp, went straight to his tent alone, and sent all the guards out, "Elf! Ren Chao shouted softly.

"What's the instructions, dear user!" The elf naughtily turned his head in front of Ren Chao and said with a smile.

"Can I now use the guò system to exchange this wooden-handled grenade newly invented by our arsenal?" Ren Chao asked directly to the point, as a pseudo-military fan from later generations, Ren Chao knew that grenades played a huge role in trenches, and after this actual battle, Ren Chao also saw the power of grenades with his own eyes, so he naturally hoped to equip the troops with grenades, but now the production capacity of the arsenal is really limited, and Ren Chao can only ask the system for help again.

"As I said, as long as there is something in this world, it can be exchanged through the guò system, and of course anything you have newly invented! It's just that if you want to exchange this kind of wooden-handled grenade, it is much more expensive than your self-sufficient production of raw materials, are you sure you want to exchange huàn? The elf patiently explained to Ren Chao.

"Yes!" Ren Chao nodded, frowned and thought for a moment, "Now that the battle situation is urgent, I can't take care of so much, you can immediately give me five thousand grenades!" ”

"As you wish, dear user!" The elf said with a smile, as if a profiteer had just made a big deal. "Five thousand grenades have been sent to the warehouse, please pay attention to check them!"

"Someone!" Ren Chao turned his head and shouted loudly outside the tent.

"What do you command?" One of the guards walked in quickly.

"Inform the 3rd and 4th regiments and ask them to come to the warehouse immediately to receive grenades, each regiment will receive 2,000 grenades!" Ren Chao commanded casually.

"Yes!"

Ren went beyond the tent and strode into the command room next door, where a group of operational staff officers were busy nervously, and the heralds were constantly reporting the latest information in and out. As soon as Ren Chao walked into the big tent, a staff officer came over and handed over a piece of paper, "My lord! This is a summary of the latest information and battle conditions. ”

Ren Chao took it and glanced at it casually, and saw that there was no particularly important information, so he casually put it on the table. Strode to the side of a huge sand table in the command room, looking at the small flags representing the two armies planted on the sand table, Ren Chao couldn't help frowning and thinking.

This sand table was made overnight by Ren Chao's people, and hills, rivers, and cities were piled up with sand. Unfortunately, due to the limited time, only the terrain around Seoul was created. The sand table is not Ren Chao's invention, this kind of thing has been around for a long time, but it was not widely used until the First World War.

It is said that when Qin was deploying to destroy the Six Kingdoms, Qin Shi Huang personally piled up and studied the geography of each country, and with the assistance of Li Si, he sent the general Wang Jian to carry out a unified war. Later, when Qin Shi Huang was building the mausoleum, he built a large topographic model in his own mausoleum. In addition to mountains, hills, and cities, the model also simulates rivers and seas with mercury, and uses mechanical devices to circulate mercury, which can be said to be the earliest prototype of the sand table, which has a history of more than 2,200 years.

It has been recorded that in the eighth year of Jianwu of the Han Dynasty (32 AD), when Emperor Guangwu conquered Tianshui and Wudu, the general Ma Yuan "gathered rice for the valley and finger painting shì", so that Emperor Guangwu suddenly had the feeling of "being captured in my eyes", which was the earliest sand table operation.

In modern times, in 1811, von Leswitz, a civilian military adviser to King Frederick Wilhelm III of Prussia, made an elaborate model of the battlefield out of clay, using colors to represent roads, rivers, villages and woods, and small porcelain blocks to represent troops and weapons, which were displayed in the Potsdam Palace and used for military games. Later, Leswitz's son used sand tables and maps to represent the terrain and landforms, and used a chronograph to represent the deployment of troops and weapons, and planned strategically according to actual combat methods. This kind of "war game" is the modern sand table operation.

Ren Chao built this sand table in order to have a more intuitive understanding of the terrain around Seoul, so as to arrange troops and try to use the local terrain to fight the little devils.

Looking at the sand table in front of him, Ren Chao couldn't help but be irritable, the devil is powerful, although the tiger army is not afraid, but it can't win quickly, Ren Chao is not afraid to drag it down! Because Ren Chao has a system in his body, the Tiger Ben Army can be replenished in battle, so Ren Chao is not afraid of fighting a protracted war at all. But I'm afraid of the battlefield on the southern front, if the new Korean army of Jeon Junjun can't successfully stop the first division of the Japanese army, it will be troublesome! So in order to prevent the loss of the southern route, we must do our best to solve the little devils on the northern route!
