If the world is peaceful, keep it; if the world is not peaceful, you can offer the crossbow to the master, if you can help the four seas to be calm, the people are happy, and there is knowledge under the remaining spring, you should feel very gratified, so as to live up to the trust of the three hundred craftsmen.

After reading the words, Mo Xiang couldn't help but sigh a few times, with her cleverness, of course she could think of the so-called Your Majesty three hundred years ago, that was the last Xiaowu Emperor of the Great Song Kingdom, and the ancestors of the Mo family turned out to be the chief of the court craftsmen of the Great Song Kingdom, and came to Bingzhou to build an underground palace, but also to keep a big secret.

Compared to Mo Xiang's movedness, Fang Ling looked silent on the surface, but deep down in his heart could only be explained by shock.

The strength of any country is inseparable from the military, and the strength of the military is not only well-trained troops, flexible strategies, but also has the most direct relationship with weapons.

Weapons should have stronger lethality, which has a lot to do with the purity of ores, smelting processes and weapon manufacturing processes.

Therefore, in the past wars of various countries, it is necessary to seize mines, especially iron mines.

Of all the weapons of war, melee weapons are in the same form as swords, guns, swords, spears, etc., while ranged weapons are the most lethal with crossbows.

The crossbow is a bow equipped with an arm, which is composed of a crossbow arm, a crossbow bow, a bowstring and a crossbow machine, because it has a longer range than the bow, the lethality and hit rate are higher, and it is a powerful long-distance killing weapon on the earth today, and the range of a high-quality crossbow can reach more than 1,000 zhang, which is far beyond the range of the bow.

However, crossbows have other disadvantages compared to bows, because crossbows are very bulky, not only do they not change their carrying, but also after each crossbow arrow, it takes a long time to reload the arrows, and during this time there must be an archer to cover, otherwise it will become a target for the enemy.

After painstaking research by craftsmen, the repeating crossbow was developed hundreds of years ago, and the repeating crossbow can be equipped with several crossbow arrows at the same time and fired in turn, filling in the shortcomings of the crossbow. However, although the number of consecutive shots of the crossbow has increased, its lethality has been greatly reduced, and the firing range is only three or four hundred zhang, and even the bow and arrow are insufficient.

Therefore, there are only two kinds of crossbows that are popular on the earth, heavy crossbows and repeating crossbows, both of which have their own advantages and disadvantages, and they also need the cover of archers.

Emperor Xiaowu of the Great Song Dynasty was reckless and had great ambitions, that is, to unify all the countries on the earth, so since he succeeded to the throne, the research and development of weapons has not stopped, and this Tiangong crossbow is one of the things recorded in history.

It is said that the Tiangong Divine Crossbow ordered by Emperor Xiaowu to be developed was to integrate the performance of a repeating crossbow and a heavy crossbow, which could not only fire continuously, but also have high lethality, destructive power, long range and high hit rate.

If such a perfect crossbow is really developed, then it is equivalent to the official birth of a weapon that completely surpasses the bow, which is of great significance for war.

If it is mass-produced and used on the battlefield, the strength of the Great Song Kingdom will increase several times, which is enough to affect the general trend of the world!

It's just that according to historical records, before the study of the Tiangong crossbow was completed, Emperor Xiaowu died, and there is no record of this thing in the world since then.

But I never thought that the rumored artifact in the world would lie quietly at the bottom of this Bingzhou city for three hundred years!
