Ma Jun pointed to an old wooden root stacked twenty paces away, and signaled for a test shot.

Because Zhuge Liang had instructed him on the use of the crossbow half a year ago, Jiang Wei was no stranger to it, so he held his breath and aimed for a while, and suddenly pulled the trigger.

But hearing the sound of "whooshing" incessantly, every time he pulled the trigger, he could send out a arrow, and the box above the crossbow machine immediately dropped a arrow to the arrow slot, and then pulled the trigger, and another arrow screamed away.

As if he had been counting the moments, he pulled the trigger seven times in a row, and the arrows were like a raging storm, and they all hit the roots of the trees in a dense manner; When I got closer, I saw a third of the arrows being shot into it.

Jiang Wei was surprised when he saw this.

Half a year ago, Zhuge Liang's wife Huang Yueying once said that this thing is clever, but its strength is soft, and it can only shoot more than 20 steps, which is a tool for preventing theft from the people, not a military tool.

But judging from today's point of view, the repeating crossbow shot from twenty paces away can still achieve three points into the wood, and it is obviously quite lethal.

At this time, Ma Jun stepped forward and explained:

"Lian...... The repeater could have shot ten arrows, but the power of one string was ...... If you want to fire ten arrows in a row, it is difficult to ...... It is inevitable that the successor will be weak. Therefore, Jun first mixed ...... with yak tendon Mixed with fine silk heavy ...... The crossbow string is re-tanned, which multiplies the string force and ...... and reduced ten arrows to seven arrows, then one ...... With one arrow, the range and power can be doubled, the most ...... Up to 50 paces. ”

"Fifty steps, ......"

Jiang Wei looked at the crossbow in his hand, and said in his heart, although the strength of the crossbow has increased greatly, it is still slightly insufficient compared to the traditional bow and arrow, which is quite a bit of a chicken rib.

The strong bow of the infantry can shoot up to 100 paces, and can ensure effective damage within 70 steps, and at least three rounds of intensive fire can be completed before the two armies clash.

Judging from the performance of the crossbow twenty steps away from the wood, the effective killing should be within thirty or forty steps; If the two armies were already thirty paces closer, they would almost be charged hand-to-hand combat, and even the crossbows would be of little use; Moreover, the arrows of the repeater are short, and if you face a soldier wrapped in iron armor, it is almost impossible to break the armor.

He looked at the dense array of short arrows at the base of the tree, and shook his head unconsciously.

Just as he was about to put it down, Jiang Wei suddenly remembered what Ma Liang said that day, "There is no month in Nanzhong that there is no rebellion, and there is no day when there is no chaos".

The imperial court's policy towards Nanzhong was to focus on Fu, and there were not many troops stationed, and in time, the rebellion of the wealthy people in Nanzhong seemed to be inevitable; If it is enough to make a small fight, if there is a sudden concentration of riots at the critical moment of the Northern Expedition, will it not be in danger for the great cause of the Northern Expedition?

He suddenly thought that the lord ordered him to organize a new army, probably to coordinate the Northern Expedition, and as a Tianshui person, he thought that he should lead an army out of Qishan West and raid the three counties of Longyou.

From Hanzhong to Longyou, there are rugged and difficult mountains along the way; Coincidentally, the South Central Zone is also mountainous and inaccessible.

In this way, after the formation and training of the new army is completed, if there is an opportunity to go to the south and central to train before the official Northern Expedition, not only can we solve our worries in advance, but the new army will also be able to train in battle, wouldn't it kill two birds with one stone?

Thinking of this, Jiang Wei secretly made a decision in his heart: "If there is really a rebellion in Nanzhong, I will ask the lord to suppress the south...... This matter is foreseen, and if it is not prepared, it will be harmful! ”

He raised his repeater again and looked at it, and said in his heart:

"The crossbow shooting does not wear the Wei army in iron armor, but the iron industry in Nanzhong is not developed, and the local soldiers are not covered with armor and fur, and more are still untouched, naked, and the mountains are dense, and the mountain roads are narrow, if the two armies meet, our army continues to strike with the crossbow, but it can cause a large number of casualties......"

"Well, mountain warfare...... Mountain Warfare ......"

He gradually fell into deep thought, and suddenly, his mind was bright, and the whole person seemed to have fallen into a new world, and a new and bold tactic suddenly emerged......

He began to rub the repeater lightly, and the corners of his mouth could not help but rise.

"Baby...... What a baby! ”

******

Subsequently, Ma Jun led Jiang Wei to the study.

I saw that on the wall of the study, the workman hung a drawing with a silk cloth as the bottom, on which was painted a device like a big scale, and there was a bucket hanging at one end of the "balance", which was filled with large and small stones, and many ropes were hung at the other end.

Seeing this, Jiang Wei asked, "Wei's stone cart?" ”

Ma Jun bowed his head and said, "It's ...... Precisely. When fighting, the soldiers ...... Pull the rope hard together and ...... The end of the stone is ...... And it was quickly warped, and in this way, the stone ...... The stone was thrown against the enemy. ”

Jiang Wei sighed: "In the battle of Guandu twenty years ago, Yuan Shao's army built a dirt mountain, erected a high oar, and crossbowmen shot arrows on it, forcing Cao's army to walk with a shield. Cao Cao's strategist Liu Ye offered a plan to break the building with a stone cart, Cao Cao accepted it, and the building was wiped out, and Cao's army lifted the threat, reversed the crisis, and won a decisive victory. Since then, the stone cart has become a blockbuster, and the princes have rushed to follow suit, but they often have the shape but not the god. I don't want to be cracked by Deheng today. ”

Ma Jun shook his head and replied, "Hair ...... Although the stone cart is good, there are also some ...... Many drawbacks, such as the fact that every time it is fired, it ...... It takes a lot of manpower and time to load; And the strength can only break through the wooden ...... Plank, right ...... Dealing with the walls of masonry, I am afraid...... I'm afraid and powerless. ”

"Oh?" Jiang Wei suddenly became interested and asked, "Is there a way to improve Deheng?" ”

Ma Jun nodded, took out a piece of silk paper from the shelf, and spread it on the desk.

Jiang Wei bent down to take a closer look, and saw that there was a picture of a new-style stone cart drawn on it, compared with the old style of the stone cart, the structure of this artifact was slightly adjusted, and there was an extra wooden wheel in the middle.

But Wen Ma Jun pointed to the wooden wheel and introduced: "Jun...... Jun borrowed from the design of the repeater, hanging the stone on the wooden ...... On the wooden wheel, load the machine...... The mechanism drives the wheel to turn rapidly, and you can catch the big rock...... Shoot out one after another, so that the enemy has no time to defend. ”

Jiang Wei compared the two drawings and slowly came to an understanding.

The old style of the stone cart belongs to the lever type of force, but Ma Jun changed him to a rotary type of force this time, borrowing the power of machinery to increase the speed and power of the stone cart stone, and its power is more than double compared to the old style!

Nowadays, the field battle of the Han army can be worthy of any army, but the siege is the weakest point, if the Northern Expedition can have such a sharp weapon to help, the siege of the city and the village, at least two percent of the chance of victory.

He was overjoyed and asked anxiously, "Is there a real thing?" ”

Ma Jun shook his head and said, "The drawings are still ...... It is still improving, and the year is approaching, and Boyo does not notice my work...... Are there not many people on duty in the workshop? But they are all on vacation, so they are the most ...... It won't be until the beginning of spring next year at the earliest...... to create experiments. ”

"It's still too late."

Jiang Wei bowed his head slightly, patted Ma Jun's shoulder again, and encouraged:

"Please also ask Brother Deheng to study it, this is a heavy weapon of the military, if the thing can be created, it will be a great achievement!"

"Jun introspective...... Provincial. ”

After the visit, Ma Jun personally sent Jiang Wei to the door.

When he paused to say goodbye, Jiang Wei suddenly turned around and said, "In a few days it will be Chinese New Year's Eve, my brother Zhang Yuan is seriously ill, I am inviting all partners to visit and pray together, if Deheng has leisure, please go together." “

Ma Jun said: "You should obey." “

Jiang Wei nodded, turned around and strode away.
