Chapter 99 The test gunpowder has been produced, and as for what weapon form it will appear in on the battlefield, Liu Yin has already thought about it carefully. Muskets and artillery have always been the biggest expectation in Liu Yin's heart, if he can have a formed musket and artillery unit at this time, let alone destroy Deng Ai, even if it is to sweep the world, it is definitely not a dream.

But reality is reality after all, the level of governance and refining in the Three Kingdoms era is simply not enough to make high-precision weapons such as guns, even if Liu Yin has the intention to improve the current level of governance, time is not allowed, in the future, if there is time and conditions, Liu Yin will definitely consider manufacturing muskets and artillery, but now time is pressing, Liu Yin is only making some simple gunpowder weapons to prevent the destruction of Shu.

Simple weapons include throwables, explosive-powder packets and home-made mines, although these weapons have a lower range and power, but they will also be a shocking move for the Three Kingdoms era, which is completely cold weapon warfare.

The simplest is a gunpowder arrow. On top of ordinary arrows, a paper tube similar to a two-kick cannon is tied, the paper tube is filled with granular gunpowder, and before firing, the fuse is lit, and then fired through a bow and crossbow and other devices, and if you hit or miss the target, it will explode.

Gunpowder arrows are characterized by a long range, and since they are tied to arrows, the arrows can shoot as far as the gunpowder attack distance is. However, due to the limited amount of gunpowder (too much gunpowder will seriously affect the range and accuracy of the arrow), the power of the explosion can be imagined, and it can cause a certain degree of damage to enemy soldiers, but it is obviously not lethal enough.

However, the benefits are also obvious, after the arrow hits, the gunpowder explodes, which can cause secondary damage to the enemy soldiers, and if it can hit the vital point, such as the eye, it can make the enemy soldier ineffective. Large-scale application in combat can also produce a deterrent power against the enemy.

More importantly, the gunpowder arrow is simple to make, and there is almost no technical difficulty, but it is slightly improved on the basis of the existing bow and crossbow, and a powder cartridge in the form of a paper cylinder can be added to the mass production.

So Liu Yin designed a kind of "grenade" while considering the mass construction of bows, gunpowder arrows and crossbow gunpowder arrows. This grenade is completely made of local materials, using a wide range of bamboo in Shu as raw materials. First of all, select the bamboo with the thickness of the arm, cut it into about eight inches for a break, after drying, one end is sealed with cement, and the granular gunpowder is filled in the bamboo tube, in order to increase the killing effect after the explosion, the gunpowder is filled with iron balls the size of soybeans in diameter, and it is still sealed with cement after compaction, and the fuse is installed in the hole that has been drilled on one side of the bamboo tube, so that the bamboo grenade is completed.

When used, the fuse is lit and thrown by the soldier, and the distance of the throw depends on the soldier's arm strength, usually up to about 50 to 70 steps. Compared to gunpowder arrows, bamboo grenades filled with about ten times more gunpowder are much more powerful. In addition to the shock wave generated by the explosion of gunpowder, which can cause casualties, dozens of small iron balls placed in each bamboo tube will also fly out as the bamboo shell bursts, causing a wide area of damage to enemy soldiers, and this grenade is more effective when the enemy is in a dense formation.

In addition to gunpowder arrows and bamboo grenades, Liu Yin also made a large number of stone mines. The stonemasons were ordered to take a stone with a diameter of about one foot, carve it into an approximate ball, chisel out the inside of the stone ball, fill it with granular gunpowder and iron balls, install the fuse and seal it.

Stone mines are loaded with five or six times more gunpowder than grenades, and natural explosions are more powerful. However, the mine is much heavier, it is impossible to throw and launch, it can only be planted on the enemy's path, and when the enemy passes, light the fuse, the explosive power of a mine is already very amazing, if multiple mines are detonated at the same time, it can be called a weapon of mass destruction.

In this way, Liu Yin quickly completed the design and development of three gunpowder weapons in the far, medium and near, and quickly produced samples. On this day, Liu Yin led people into the Xiling Bison Valley with samples to prepare for weapon tests.

Zhang Le and Zhao Zhuo, two sworn friends, were also invited to Bison Valley by Liu Yin.

"Big brother, it's rare that you are so interested today that you actually want to invite the two of us to hunt? But when it comes to hunting, it has to be the Qingcheng Mountain Enclosure, this bison valley sounds good, not to mention a bison, even pheasants and hares are not common, hunting here, it's really not good! Zhang Lexing rode his horse in a hurry, but looking at the environment of the Bison Valley, he couldn't help but complain.

Zhao Zhuo has never been smiling, since Liu Yin was warmly invited, he was not as big as Zhang Le, he smiled at Liu Yin very calmly, and hugged his fists to salute.

Liu Yin had already appreciated Zhang Le's virtues, and he didn't care, smiled slightly, and said, "I invited two virtuous brothers to come today, and I didn't come to hunt—"

"Not hunting?" Zhang Le's eyes widened, and he shouted, "Then what are you doing in this ghost place?" See the scenery? Poor mountains and bad waters, what's so good! ”

Liu Yin smiled leisurely and said, "Please come, I want to witness the moment of miracle!" ”

"What's that?" Zhang Le's mind hasn't turned a corner yet.

Liu Yin took an arrow, pointed to a little yellow sheep tied to a tree in front of him, and said, "Brother Le, this first arrow, you will shoot it." ”

"Isn't this still hunting?" Zhang Le muttered, although it was said that the yellow sheep was tethered, and there was less fun in chasing prey, but he could shoot arrows, which was worth the trip. However, when he held his bow in his hand, he noticed that there was something unusual about the arrow.

The cluster of arrows was no different from usual, but behind the arrows, there was a paper tube-shaped thing, about an inch thick and more than four inches long, and a thin tail dragging it.

"What the hell is this?" Zhang Le was stunned for a moment.

Liu Yin took a burning charcoal strip, and a red flame could be seen on the top, and said, "Brother Le, you just shoot arrows like usual, and shoot arrows out." ”

Although Zhang Le was very curious, Liu Yin didn't say anything at this time, so he could only use his bow and arrows and aim at the little yellow sheep.

At this time, Liu Yin told him not to shoot out in a hurry, and ignited the thin tail with a charcoal strip.

"Shoot fast!" Just when Zhang Lezhang and the second monk were confused, Liu Yin urged him, Zhang Le's hand loosened, and the arrow shot towards the little yellow sheep.

Due to the hasty shooting and the fact that a paper tube was tied to the shaft of the arrow, Zhang Le's arrow shot was a big failure, originally he aimed at the head of the yellow sheep, but it ended to shoot the front leg of the sheep.
