This time, a total of 60 cannons were sold to King Zhi, 40 6-pound cannons, and the unit price was 40,000. Fifteen 12-pound cannons, the unit price is 55,000, and five 18-catty cannons, the unit price is 80,000, which is equivalent to more than 280,000 yuan per inch of silver.

In fact, flexible payment methods are adopted, and only a small part of them are traded in gold and silver, and the rest are settled in Xianguo gold and silver Tongbao and Zhiguo copper coins, as well as equivalent goods, considering the risk of scrap, this price is actually not high.

The smaller the caliber of the gun, the higher the yield of casting, and the larger the caliber, the higher the scrap rate, since the technical difficulty increases significantly with the volume and weight of the casting.

Taking Changsun Guo's five-kilogram cannon and Yongxingcheng's six-kilogram cannon as examples, Bailiyan has calculated that the cost of a single Changsunguo five-kilogram projectile cannon is only five or six thousand inches of silver than Yongxing's six-kilogram cannon. Among them, there are not only iron price differences, labor and trade differences, but also scrap costs.

But compared with the seventeen-pound cannon of Changsun Country and the eighteen-pound cannon of Yongxing, its average cost has almost doubled, the eighteen-pound cannon of Yongxing is about forty-seven thousand, and the cost of the seventeen-pound projectile cannon of Changsun is nearly seventy-thousand, and the price is more than 100,000.

The gap is no longer due to the factors of labor and iron prices, but the huge difference in the scrap rate between the two caused by the technical generation difference, which is evenly apportioned to the unit price of artillery. [Note 1]

And the larger the caliber, the higher the scrap rate of casting guns, and even the success rate of casting super-large caliber guns is close to zero.

This batch of arms will be paid with gold and silver for 10% of the total price, gold and silver Tongbao will pay for 20%, and the rest will be paid for in Zhiguo's copper coins, grain, cotton, Dadu, iron ore, sulfur, coal, medicine, cattle, war horses, livestock, leather, minerals and other bulk commodities.

The cash will be paid after the first batch of fifteen artillery pieces are delivered to the Zhi Army, and Bai Liyan plans to use this money to purchase fifty twelve-pound guns and eighteen-pound guns, and the six-pound artillery siege effect is average, and before the fragments, grenades, and explosions are popped out, non-heavy artillery will not be able to attack the fortification.

"Your Majesty, our army can replenish fifty artillery pieces into the front line for siege by the end of April next year at the earliest, and the last batch of artillery delivered to Zhiguo will be delivered in June or July."

"Okay, can you take the three counties of Ganfu, Shangguan, and Wanchuan at this time next year?"

"At present, it is the middle of winter in the south, except for the cavalry, the infantry, logistics, and artillery are not convenient to move, and I am afraid that there will be no large-scale battles until the ice and snow melt next year. However, the climate in the south of Changsun is mild, and it is reported that the Changsun army is still advancing southward, so the time to take the three counties of Ganfu, Shangguan and Wanchuan next year is extremely tight, so the ministers have to cast another 50 artillery pieces for siege field battles. ”

"Gongsun Yue has news, it has been more than half a year now, why is there no sincerity in the eloquent Dao?"

"Back to the king, most of Gongsun Yue has been secretly detained by Xiong Lun Dao, or Xiong Lun Dao and Gongsun Yue secretly met the inside story of the East Window incident, and there was a mistake, but the minister thought that the former was more likely.

Xiong Yandao has sent envoys to the peace talks four times, it can be seen that he still wants to talk, and the detention of Gongsun Yue, most of them is to use it as a bargaining chip, and the king bargains, if the king does not obey, he will make Gongsun Yue public, so as to slander the name of our Xian country. ”

"Damn!" King Xian scolded: "These eloquent scum, the widow sincerely lobbied them, but now they are framing the widow and despicable!" ”

"My lord, there are pros and cons to everything, and it is unreasonable to have smooth sailing without any risk. Moreover, the seizure of Gongsun Yue by eloquently shows that he is weak-minded, and he just wants to raise his own value by procrastinating and waiting for change, looking for more favorable opportunities, so as to seek more benefits and benefits.

Therefore, the minister thinks that now the time is in me, not in the black scarf, at the beginning of the war next year, if the war is still going well, you can first put the Xiong Dao aside and ignore it, and when the army of the vassal states kills it, the Xiong Dao must always seek a way out, otherwise it will definitely be brutally suppressed by the vassal states. ”

After Gongsun Yue was detained, Xiong Yandao secretly sent envoys to the tomb four times, and each time he repeated the same old tune, demanding a truce on the western front of the Xian army and the Zhi army.

But it turned out that it was the first time that the army was suspended, causing the supernatural king Li to withdraw from the northwest to the south of Ganfu County within a month, and also brought more than 30 cannons, giving the Black Turban Army a huge respite.

As he spoke, King Xian changed his words and mentioned the mausoleum again:

"Aiqing, how did the widow find the auspicious land?"

"Oh, King Qiyu, Si Tianjian has found an auspicious land south of Miaotian Mountain, which can be used as a 10,000-year spiritual vein, and Si Tianjian is making in-depth calculations in order to demarcate the best tombs. However, the minister suggested that the war is now tight, and the digging of the tomb may have to be postponed. ”

"The mausoleum can't be delayed, according to the widow's view, after the auspicious place is selected, the tomb can be broken and excavated first, and the rest can be said later."

"Your Ministers obey."

Zong Botai once said that there is auspicious land in the south of Miaotian Mountain, and Bailiyan was also skeptical at that time, because for hundreds of years, Si Tianjian has more feng shui masters, and Miaotian Mountain is a famous mountain in the North Sea, and its surrounding terrain cannot be ignored.

However, in fact, there are some things that cannot be explained.

Si Tianjian once looked for the officials of the auspicious land for the first king, and went to the vicinity of Miaotian Mountain more than 40 years ago to investigate, but did not find any auspicious spiritual veins at that time.

Not only did the officials of Si Tianjian determine that there was an auspicious spiritual vein in the south of Miaotian Mountain, Bailiyan invited the master of the Ligong School to personally investigate on the spot, and after repeated investigation and calculation, it was found that Miaotian Mountain was located on the "first line of heaven and earth".

The so-called "one line of heaven and earth", Bailiyan was confused at first, and went to the field with Zong Botai to investigate, and finally understood what the so-called "one line of heaven and earth" was, and said that it was the meridian of the central axis.

Affected by the rotation and curvature of the planet, the time zone is divided by longitude, if the planet is spread out into a plane, the rotation of the planet and the movement of the sun form a sine wave trajectory from east to west, so there must be a highest point of the longest solar shadow length in a specific number of time zones.

During the whole cycle, the Sun has several cycle highs, and only one of these cycle highs will be the highest point of the Sun at noon in the rotation of the planet.

Among them, the northern hemisphere has, a southern hemisphere has one, the northern and southern hemispheres should be symmetrical, located in a meridian line, after forming a line, every day at noon at twelve o'clock, when the sun passes through this line, the shadow length is the longest, this line is not only the central axis of the planet, but also can be used as the prime meridian.

The whole planet is just like this, passing through the center of Miaotian Mountain impartially, if you want to say coincidence, it should not be coincidental at this juncture.

It is not difficult to find that hundreds of years ago, mathematics in the Central Plains was not developed, and the monistic method had not yet appeared, and the promotion of the monistic method was more than 70 years ago.

Observing celestial bodies to calculate the motion of the stars, which requires at least the binary method to complete, is a co-development of mathematics and astronomy, which ultimately led to today's results. The spiritual vein has not changed since ancient times, what has changed is the trend of the times and technological innovation.

Once the prime meridian was determined, Bailiyan later used this line as a benchmark to solve the problem of longitude positioning that had been disturbed for more than 20 years in one fell swoop, thus laying the foundation for the future manufacture of sextants and theodolites and the expansion of astronomy and cartography.

Jiang Hai, the king of Xian, also became the first and last emperor in history to use the middle line of the meridian as a mausoleum.

In the next few days, Bai Liyan and Tao Chun met twice to finalize the delivery time and details, and the first batch of 8,000 grenades was handed over to Tao Chun to be transported back to Zhiguo, but there was an unpleasant incident in the future.

As a product, there is always a certain probability of defective products, and wooden-handled grenades, as a semi-enclosed weapon, greatly solve the problem of humidity in early rudimentary gunpowder weapons, but cannot fundamentally solve the problem of storage and deterioration.

This time, Zhao Xun went south and westward, and successively found that the quality of grenades, on average, 13 out of 100 could not be pulled, the problem was either in the filling and assembly, or improper storage and moisture failure, and at the same time, the rain had a great impact.

The grenadier armed bag grenade has the wooden handle facing upwards, and under normal circumstances, it should be sealed with a threaded metal cover, unscrewed and then pulled when used, in fact, it is not possible to make threads at present, and can only be blocked with wooden plugs, which leads to flooding in rainy days and is easy to fail.

This problem did not occur until two years later, when oily wax paper was pasted into the wooden handle to block the ignition opening, sealed with paraffin wax and plugged with a wooden stopper, so as to isolate the air and humidity.

When using, you only need to unscrew the wooden stopper, poke the paraffin wax and oil wax paper with your fingers, and expose the pull ring.

The batch of grenades bought by King Zhi belonged to the early type, and only more than 3,000 were used before and after, and the rest were pressed in the warehouse as treasures. When I used it again a few years later, I found that nine out of ten could not be pulled, so I came to the door to change the goods.

Of course, King Zhi has not been without the intention of imitation, but he has never understood the composition and principle of the ignition tube.

After Gongliangxiu got the grenade and medicine, he returned to the Changyin front before Tao Chun, who waited until the end of December to leave.

On December 17, Bailiyan went to Yongxing to arrange cannon casting and appropriation, but Zhiguo's money had not yet arrived, so it could only be advanced by the national treasury, Qianfang, Houfu, and Yongxing City.

Bao Ning and Cheng Jiyuan's gas has been completely eliminated, but as expected, after the Xianjun artillery came out, Changsun Guo restricted more than 20,000 people from leaving the country on the grounds that the Ligong faction was stealing technology.

Although the prison was confiscated, it was no different from house arrest, and there was no request for the time being, Bai Liyan suspected that it must be the lord of the eldest grandson who sat and waited for the Xian army to conquer the land of Sun State, and then used 20,000 people to make a fuss about it, and wanted to blackmail Xian Guo to give up land.

The number of "wooden whirlwind wooden column carts" built by the Gonggong faction increased from six to eighteen after six months of operation, and they could cut soft iron, copper, and pig iron at a slow speed, but the problem was that there were no knife holders after this thing was built.

The processing process of logs is purely based on a wooden beam parallel to the workpiece on the front of the gyratory car, and the woodworking tool is manually held against the beam, and the tool is slowly moved from left to right or from right to left to achieve the purpose of cutting.

There is nothing wrong with this method for processing wood, but it is never possible to process metal, even pure copper, which is very dangerous. Even if it could, it could only be done with a file to assist in the filing process, and it was never possible to use a machined tool to hand the turning process with a bare hand.

In addition, the fixture is also a fatal problem, the whirlwind wooden column car uses four pieces of iron to tie the log to the power spindle with an iron hoop, and the other end is on the iron tail vertebrae erected on the ground, and not to mention whether it is safe or not, this method obviously cannot be used to process metal bars.

Regardless of the cutting force or material hardness of wood processing, it is much lower than that of metal materials, even if it is copper, the required cutting force is dozens of times that of wood.

Due to the mechanical standardization of gears, bearings and other key components of the mature, has the basis for manufacturing metal transmission lathes, Cheng Jiyuan and Bao Ning are planning to manufacture small metal rotary lathes, the meshing of racks and gears solves the problem of movable tool holders, but still can only rely on the hand cage carriage, so before the emergence of electricity and motors, automatic knife is obviously impossible to count on.

[Note 1] Advanced technology means that there will be corresponding costs, which can be time cycles, monetary costs, human resource consumption, and even life costs.

Therefore, any major technological development requires a relatively complete technology, talent, industry, and agricultural system, otherwise excessive realization of advanced technology will inevitably pay a corresponding price.

Of course, if there is a predictability of technology and cognition, this cost will naturally be greatly reduced, but a basic industrial platform carrier is still needed to carry the production of advanced technology.
