The Turks soon shot arrows again, and because of Li Junxian's order, the crossbowmen of those special guards could not be dispersed, so they had to continue to stare at the rain of arrows there with bows and crossbows to defend against the Turks, because the Turkic cavalry was waiting in the back and ready to attack at any time. But it was this dense formation that made it very easy for the Turks to aim. Although the Turks can't hit a hundred shots because of hanging shots, dozens of arrows can also hit one person!

"Ahhh......h

"General Li, this time we have more than 100 people who have been hit by arrows, eight of them were killed directly, and more than 30 of them were seriously injured. The Turks are also becoming more and more experienced, and they are actually becoming more and more accurate. If this continues, I'm afraid we won't need twenty or thirty rounds of shooting, and I'm afraid we'll lose everything! Su Dingfang said.

"Hmph, compare bows and arrows with me, they're looking for death! Let the rocket battalion of the firearms regiment prepare, this time they will be used. Li Junxian said.

Then the staff officer on the hot air balloon saw the following order to use triangulation, and the staff officer above immediately understood.

"Foreman, this time General Li asked us to use triangular ranging, how can this be used?" A staff officer asked.

The foreman said: "Actually, there is no difficulty, as long as it can be measured according to the ranging formula of the triangle taught by General Li." We first have to determine the edge of the triangle with a rangefinder crossbow, and then calculate it with the rope on this side of the hot air balloon we have here, so that we can calculate how far our rocket battalion is from the Turkic archers. ”

The foreman took out a crossbow, which had been selected, marked with a scale, and could have different winding gears. Each gear has instructions on how far the bowstring can be pulled here. This is used for ranging and calibration, and it is a crossbow for ranging that Li Junxian specially asked Master Tie Gao to research.

The foreman immediately said, "Wait a minute, let's see if there's any wind?" Tell me when the wind is almost dry. Otherwise, the bow and arrow will be skewed, so that the distance measurement will not be accurate. ”

Soon, the staff officer in charge of observing the wind said; "Foreman, now that there is no wind, you can do ranging."

The foreman took the rangefinder crossbow, then aimed at the position of the Turkic archers in the distance, then first estimated the distance, then pulled the bowstring to the estimated distance, and finally aimed at the Turks, gently pulling the trigger.

"Whoosh!" There was a thud. All the while the arrows were shot out of the hot air balloon.

"What!" The arrow stuck in the dirt.

But the Turks didn't care at all, because the arrow was still a long way away from them, so they were not afraid at all. However, the reconnaissance staff officer who went to the top of the hot gas secretly estimated the distance, and then adjusted the strength of the rangefinder crossbow again according to the distance, and finally fired an arrow again.

"Whoosh!" An arrow hit the foot of a Turk, but it didn't hit the Turk either.

"Hahahaha! The Han people are exhausted in donkey skills, and they actually want that flying thing to shoot us? How many people can that flying thing hold, how many of us can it shoot? Turkic warriors, don't be afraid of the Han Chinese. You keep shooting. The Turkic captain of the archers shouted.

"Whoosh whoosh......" The Turks shot arrows again.

"Ahh......hh

Li Junxian saw this situation, and immediately shouted to the staff officer on the hot air balloon: "You guys, follow up with me faster, otherwise I will engage in your military law!" ”

The reconnaissance staff officers on the hot air balloons immediately became anxious. Immediately start deducing from the distance of that arrow. The so-called triangular ranging is to calculate the length of the third side according to the sides of two triangles. The diagonal distance between the hot air balloon and the Turks is now exactly one side, and a crossbow arrow is shot from the hot air balloon. It is to measure the distance of this edge. However, because it is a diagonal line, this edge is not precise and cannot be used as data for the soldiers of the rocket battalion. The range of the rocket battalion is increased by one degree at a time. That would cause a big error, so you should never make too much of a mistake.

And after determining the side of the diagonal line of the hot air balloon to the Turks, the distance from the ground to the Turks can be quickly measured. Because the other side is actually the length of the rope from the ground to the hot air balloon, as long as the length of the rope is determined, it is equivalent to determining the other side. Once you have two edges, you can use the formula to calculate the length of the third edge. This knowledge is actually available in junior high school mathematics, but it is a very advanced thing in ancient times, if it weren't for Li Junxian, a traverser, I'm afraid they wouldn't have been able to learn it at all. This is also the method used by Li Junxian in order to conduct long-distance calibration for the firearms unit.

"General Li, they've measured it!" Said the staff officer below.

Li Junxian opened the crumpled note, and immediately gave an order to the firearms battalion: "Yang Wu, we are five hundred meters away from those Turks here, you can tell the soldiers of the rocket battalion to quickly launch rockets and suppress those Turks." Those Turks are too arrogant to take our bows and arrows seriously. The soldiers have crossbow arrows in their hands and can't shoot them in a sling, so they can only rely on your rockets. ”

In the Turkic troops, the captain of the Turkic archer was very happy, because he was about to get a high position. This time, it was not the traditional Turkic cavalry that contributed the most, but the archers in their own hands. If these archers can kill the most enemies, then I am afraid that the captain of the archers will be able to obtain a noble title in the future Turkic Empire. Now the Turks want to form an empire, and this is already open. Many people want to make meritorious deeds at this time, so that they can obtain knighthoods in the future empire. This is very happy for the Turks at the bottom, and the only ones who are unhappy are those who have many tribes.

Now the captain of the archer wants to get credit as soon as possible, so that he can get a knighthood in the future. How did the credit come from, and it didn't come by killing the enemy? If these archers kill enough enemies, they can pave their way to the nobility with the blood of the Han Chinese. However, these are just YY in his heart, Li Junxian is not a vegetarian, can he be allowed to YY here? (To be continued......)
