In addition to the "Barefoot Doctor's Handbook", when Liang En met with the prefectural magistrate this time, he also brought something like a hand-cranked rotary pencil sharpener.

This thing has a very simple purpose, that is, to process square or other shapes of long strips of wood into small long sticks, which can be regarded as a simple hand-cranked lathe.

But for the ancient world, this machine was a strategic piece of equipment, as it was able to quickly process the most difficult part of an arrow to machine, the shaft.

Yes, bamboo in the south is able to meet a large part of the demand for arrow shafts, but the real elite prefer to use arrow shafts made of solid wood and bird of prey feathers.

"It's a small thing, but it's very useful." To this gadget that Liang En brought. Zhang Xianling also gave a very high evaluation.

"That's great, I've been worried that this thing won't work." Liang En smiled, "Because I saw that the arrows used by our archers here are all made of bamboo. ”

"But the archers in the army, the mobilized mountain ghosts, and some of the heavy crossbows need carved arrows with solid wood as shafts, because only this weapon can use their archery skills."

Zhang Xianling's expression now looks much more relaxed than before, and it is obvious that the good news and materials brought by Liang En this time have made him obviously a lot easier.

In the next few days, Liang En successively transferred nearly 50 tons of supplies to this world, and at the same time, he also saw that all kinds of preparations for war were getting bigger and bigger, and they were becoming more and more open.

For example, outside the city, large-scale fortified wilderness has begun, and villages have either been relocated or walled. At the same time, the army also left the garrison to build some temporary fortifications with the temporarily recruited migrant workers, and began to move into their respective defensive positions.

"- The sailors have already fought several battles with the pirate ships at the mouth of the Yangtze River." After hearing Liang En's inquiry, Tian Zongqi, who had already been ordered to rush back, explained the reason for the large-scale preparations now.

"There is no doubt that the war has begun, and no one can stop it at this time, but it is good that it can be shown that the chariots and horses will have a good fight."

According to Mr. Tian, it can take months or even years of energy and a lot of material to organize an attack of this level, especially if the people being organized are a group of armed forces from different forces.

Therefore, even if the attacker really knows that the target of the attack is prepared, he can only slightly change the route or method of the attack. But the overall situation cannot be stopped.

In particular, the organizers of this large-scale attack came from the remnants of the previous dynasty, and this time it can be regarded as a desperate fight under the condition of being suppressed for a long time, and if it is abandoned halfway, then it will be impossible to organize an army of this scale in the future.

"—So even if the attackers knew that we had made preparations, the other side would still attack according to the plan, not to mention that we are only monitoring the hidden stakes they have planted and have not pulled them out, so the other side is likely to attack by chance."

"I see." Liang En nodded and looked out the window.

Outside the window were more than 100 young people, including Lang Zhong, soldiers, and some ordinary civilians who had been improvised and had come here to learn rescue techniques.

"Thanks to the books and those things you brought, with these things, I think more people should be able to survive this war." Tian Zongqi patted Liang En's shoulder hard.

The technology brought by Liang En this time is not much ahead of the times, but those knowledge systems about bandaging, stopping bleeding, and sanitizing can already play a strong role after being organized.

To take the simplest example, the British army in the Crimean War originally had a mortality rate of 42%, but it took Nightingale half a year to reduce the mortality rate to 2.2% without antibiotics.

In particular, when a series of rules such as paying attention to ventilation, drainage, and overall cleanliness of the ward are combined, the mortality rate will naturally be greatly reduced.

As a soldier who had fought on the northern front, Tian Zongqi could naturally see what role Liang En's summary regulations could play with the materials he brought.

Yes, this is a world of supernatural powers, but the high cost of supernatural powers and the scarcity of practitioners make those methods simply unpopular.

"After all, there's not much I can do about this war, and I'm happy to be able to help everyone." Liang En smiled slightly, "But when will this war officially start?" ”

"No one knows, but it should be the past few days." Tian Zongqi looked at the yellow leaves that were fluttering on the trees and said, "Because the current wind direction can only be maintained for seven days at most, if they don't attack, they will be blown to the open sea." ”

Just as Liang En and Tian Zongqi were speculating about when the enemy would attack, hundreds of warships stopped at sea and dropped their sails near an archipelago about 100 miles from the mouth of the Yangtze River.

"—Pu-sama, when are we going to attack?"

In the ornate stern cabin of the largest three-masted dhow, more than a dozen people of different dresses, different appearances, and even different races all stood there in full armor.

A bearded man with a covered head and chainmail came out and knelt on the ground, asking the figure sitting in front of him eagerly.

"Now the richest part of the Song people has been exposed to our scimitars, and a lot of wealth is waiting for us, but you- why are you stopping now?"

"Gosimus, are you going to question my orders?" The middle-aged man sitting in the chair across from him asked in a flat voice after the bearded man had finished speaking, while his fingers flicked a mechanism.

"Don't dare!" This bearded man with a bun head, but there was no respect on his face.

"We've been waiting here for 10 days, and we probably won't be able to return if we run out of water and food, and we're not here to eat the salted meat that grows worms. Bread and thick, green water—"

Before he finished speaking, the leaders of the forces who came to force the palace saw a sharp sword tip with blood coming out of the leader's back, and then a large amount of blood flowed out.

"As I said, I will command this war, and no one else is allowed to interfere." Pu Yanshou, a middle-aged man known as Master Pu, stood up at this time, flipped over the other party's body with his toes, pulled out a short sword, and then wiped it on the other party's clothes.

"I understand that you want money, treasures, and slaves, but listen to me when you want them, otherwise you will all go to hell."

With that, he swept over the faces of the people in the room, and everyone who saw it lowered their heads.

"Now pass my order, tomorrow at noon banquet, set off in the afternoon, and take the wind to attack the Yangtze River at night." Feeling the fear of these people in front of him, Pu Yanshou nodded and said.

"Let's rob, let's kill, fill our pockets with gold and silver, and destroy this land with blood and fire!"

"Kill! Kill! Kill! ”

There was a burst of cheers in the otherwise quiet cabin, and the fear and resentment of the corpse on the ground were immediately forgotten, and everyone had bloodthirsty expressions. In their minds, their happy hour is just around the corner.
