The smoke and dust in the sky obscured the blue sky of Nawa in late autumn, and the neighing of horses, the laughter of people, and the crisp sound of the clashing blades came with the wind, faintly but with a huge coercion.

Tang Xiaomao glanced at the dark and dreary cavalry figure two miles away out of the corner of his eyes, and slapped the back of the head of the distracted recruit next to him, "Look at a bird!" Hurry up and erect a stake! ”

Tang Xiaomao was originally the first group of guards, but he was an old man who followed Chu Fan through Nagasaki; After the first expansion, he was the captain of the B-shaped squad, just because he was usually very ruffian, and he didn't care much about learning anything, so although he was very brave in battle, he always went wrong - the biggest one was when he exterminated the squatting tiger, his B-shaped team was responsible for blocking the gate of the village, but he was shot back again and again by the squatting tiger's random arrows, and almost didn't break up.

It is precisely because of his character that after the second expansion, he is still the team leader, but he was transferred from the B-shaped squad to the T-shaped squad and replaced Chen Erdan.

He was of this character, and his T-squad was naturally influenced by a great deal of influence, and he was always absent-minded in training and fighting—this was the case with this recruit, and after eating him, he came back to his senses, picked up the wooden hammer in his hand and smashed it against the thick stake, which was soon deep in the soft earth; Tang Xiaomao pulled the barbed wire full of spikes and hung it on a wooden stake.

Tang Xiaomao looked around and saw that the two barbed wire fences more than three meters wide had been laid out, and he whistled at the brothers, "Withdraw!" Back! ”

The more than 50 members of the T-shaped squad withdrew from the middle of the two barbed wire fences into the large formation in three columns, stood in the third row, and began to form a team.

Fifty meters behind the big array, Chu Fan stood on the wall, looked down at his pocket watch, and nodded slightly—not bad. It took less than ten minutes from leaving the gate to hanging the barbed wire.

The three outposts of the Fuliao Army arrived at the foot of the hill at 9 o'clock in the morning, and as soon as they landed, they were put into the project of setting up a camp; Because the timber and ropes were well prepared, the work of setting up the village progressed quickly, and it was all completed around 1 p.m. - lunch was eaten in the village.

After lunch, the night team in charge of lookout on the hill south of the stockade blew the horn - they saw the approach of the Liu cavalry from a distance.

According to the plan agreed on Ushijima. Liu Zhongwen went out with the Gengzi whistle and the T-shaped whistle, and at the same time, there were two 6-pounder Franc machine field guns and the eight-bull crossbow.

Regarding the first battle on the island, there was a dispute between the sentry commanders and captains of the Fuliao Army; Lao Cheng is a little more serious, such as Chen Erdan, the head of the T-shaped sentry, feels that since he has worked hard to set up the camp, he should rely on the camp to fight the Liujia cavalry, so as to make full use of the geographical advantage; The radical faction, led by Shen Teng, believed that the first battle on the island should play the momentum that the Liao army should have. Only by fighting in a dignified formation can the arrogance of the opponent be completely defeated!

After discussing with Liu Zhongwen, Chu Fan supported the latter opinion, of course, they were not completely to defeat the morale of the Liu family's cavalry, but more to consider training the soldiers through actual combat, and at the same time to strengthen their confidence in facing the impact of the cavalry - the camp is just a support point, and it is really a place to defend when it is forced to come.

Besides, he was beaten in the camp from the beginning. The blow to morale is also very large.

The large array in the barbed wire protection is all ready - whether it is the first row of flintlocks. The second and third platoons, still using the arquebus, all the fighters had already finished loading their ammunition; The braziers between the platoons had also been lit for the last grenade throw.

On either side of the large array, two 6-pounder Franc field guns were also ready; The son's guns were neatly arranged, and in the brazier next to him, the iron brazier was already burned red. Just wait for an order, and you can fire.

Chu Fan looked at his pocket watch again, and the minute hand pointed to the fourteenth minute; Then he raised the clairvoyant mirror and looked at the cavalry group more than a thousand meters away, in the lens. The North Koreans, who had been sitting on the ground, began to get up one after another.

In this era, before the cavalry charges, they will rest outside the opponent's strike range to recuperate their horsepower.

Now it seems that the time for this break is about fifteen minutes.

Sure enough, Chu Fan saw that the North Koreans opened their armor bags and helped each other to start wearing armor - mainly leather armor and cotton armor, and there were several leaders who looked like them, wearing the same standard Wenshan armor as Daming.

There were two particularly conspicuous ones in the procession, one wearing dazzling bright light armor and straddling a tall divine horse under him; The other is covered in black armor, which forms a sharp contrast with the snow-white war horse under him, which is particularly conspicuous.

Putting down the clairvoyant mirror, Chu Fan turned his gaze to the Eight Bull Crossbow behind the large array, where Zhang Ziyu and Tong Mingfu were writing and painting with a white lacquered wooden board.

Chu Fan knew that they were doing the simplest and most primitive ballistic calculation.

After returning to Ushijima this time, the two math maniacs would catch Chu Fan whenever they had the opportunity to ask for math knowledge—whether it was algebra or geometry.

Soon, all the goods in Chu Fan's stomach were squeezed dry, including trigonometric functions.

Although there are many formulas for trigonometric functions, most of the formulas of sine and cosine can be derived through a few basic formulas, and these basic formulas, such as the sine formulas of 30, 45, and 60 degree angles, are something that Chu Fan will not forget - he memorized too hard when he was preparing for the college entrance examination that year.

With these formulas, plus Chu Fan taught Zhang Ziyu their derivation methods, the two of them are completely addicted to the vast sea of trigonometric functions these days.

This is also what Chu Fan likes to see - everyone knows that one of the most important applications of trigonometric functions is to solve ballistics!

So this time, Zhang Ziyu and Tong Mingfu followed without thinking about it - they wanted to confirm their obsessed mathematical theories through practice.

The movement on the opposite side suddenly became louder, and it could be seen without a clairvoyant mirror, and the cavalry of the Liu family began to form a team!

At this time, Zhang Ziyu and Tong Mingfu also threw away the white lacquered wooden board in their hands, and commanded several soldiers to start adjusting the Eight Bull Crossbow, and the two scholars even went into battle shirtless and personally put up wooden blocks under the heavy Eight Bull Crossbow.

After a minute or two of adjusting the elevation angle of the Eight Bull Crossbow, the two warriors began to shake the rocker arms on both sides of the Eight Bull Crossbow, and the thick bowstring slowly opened in the tooth-aching sound of metal rubbing, and finally got stuck in the open crossbow machine.

A crossbow bolt the size of an egg was placed securely in the arrow slot, and the lead was already lit on the conical arrow, and sparks were sparkling outward.

After a muffled "buzz", the bowstring flicked out the crossbow arrow at a speed that was inaudible to the naked eye! (To be continued.) )
