The low-level mechanical puppet drawings of Mojiasi that are too numerous to fill several rooms contain too many treasures. Unfortunately, no one has been able to discover the wealth contained in it for thousands of years.

It is not accidental that Chen Hai can see the value of these waste paper-like collections. After all, many unrealistic genius concepts in the world require the integration of Chen Hai's foreign thinking to truly shine.

Puppet Armor is just one example.

Juquanling has 50,000 or 60,000 people, but the main personnel still have to engage in production. The regular defense elite troops cannot exceed 3,000 at most. No matter how many, it will affect the efficiency of armor manufacturing. Defensive troops can only rely on various excellent combat equipment for strengthening - this should also be the most important expertise that Juquanling should do.

Just like crossbow equipment, Chen Hai had long wanted to create crossbows in Juquanling that could quickly form dense rain of arrows.

Continuous crossbows are easy to make, but powerful continuous crossbows are not easy to obtain.

The Xuanfei Iron Bow is strong enough. It can even easily tear the defense of the Xuan-level spiritual armor with an armor-breaking arrow, but Chen Hai has infinite magical power and can only shoot one arrow in one breath.

Several crossbows tried to produce Juquanling still use traditional crossbows and bowstring structures to accumulate power.

Because the accumulation of the crossbow and the bow string requires a process and takes a relatively long time. In order to be able to launch quickly and uninterruptedly, the accumulation time of the bow arm and the bow string must be greatly compressed. How strong can the crossbow arrows fired at this time have?

However, in the information of Mojiasi, it has been recorded for more than 300 years that the sects combine the talisman array with bows and crossbows to create mechanical crossbows. At this time, the sects also have records of building mechanical crossbows one after another.

The core talisman array components of a single-machine crossbow involve the category of magic weapon refining, which is much more complex than the manufacturing of a gold quenching bow. Compared with the power of a gold quenching crossbow, it will naturally not be valued by the world.

The biggest advantage of the talisman structure and the traditional bow arm and bow string structure is that it basically does not require any power storage process to fire crossbow arrows, which makes it possible for Chen Hai to manufacture mechanism crossbows in Juquanling.

Only by using the refining complex talisman arrays to use them on mechanical crossbows can it appear economical and affordable.

The mechanical crossbow is actually much simpler than the mechanical arm. Zhou Jingyuan has obtained drawings for trial production, but the early output cannot be high. The first batch of mechanical crossbows must first prepare the defense force of Juquanling. At the earliest, it will take half a year before sufficient output will be supplied to the Black Yan Army.

As for the rainy pear blossom crossbow, Chen Hai just casually proposed a concept to scare Ning Chan'er. He thought that Ning Chan'er was like everyone else. Since he mistakenly thought that he had obtained an ancient and powerful mysterious inheritance, there must be some tricks that can scare others by listening to the name.

"I have to see what the gold-tempered crossbow will look like before I can decide," Ning Chan'er said, "But Juquanling could supply us 20,000 gold-tempered arrows before."

The casting of gold quenching arrows is the simplest. You only need to smel out enough gold quenching iron materials. After the mold is poured, the arrow clusters can be forged and removed. You can even deliver the embryonic arrows directly, which are ground by the craftsmen of the Black Yan Army to sharpen them.

"Then we will see you in a month!" Chen Hai was not polite and wrote down the price codes of 20,000 gold-tempered arrows and a gold-tempered crossbow sample and handed them to Ning Chan'er.

The best spiritual medicines and refining resources in Yanjing City are controlled by the clan clans. In order to avoid being aware of the true strength of Juquanling, Chen Hai asked the Black Yan Army to directly take out spiritual medicines and refining resources to trade with Juquanling.

Ning Chan'er took the order written by Chen Hai, and her beautiful face twitched slightly, but after careful calculation, it was much cheaper than buying gold-grade armor from the black market. What's more, Juquanling really needs to have a stable large supply of goods, which is the most suitable partner for the Black Yan Army.

************************

Since her sister left quietly for a while, Su Ling felt like she was in a dream. Unexpectedly, her sister and Chen Hai had a serious revenge to settle the deal calmly, and she didn't understand what was going on!

What's going on? Although Su Ling hoped that her sister could resolve grudges with Chen Hai and get along well with her, she didn't expect it to be so smooth.

"You will follow me to Mojia Workshop tomorrow." Chen Hai said to Su Ling.

"Ah..." Su Ling was a little puzzled. She was Chen Hai's personal maid, but it was always inappropriate for her to enter and exit the Mojia workshop where Chen Hai worked.

"The crossbows in the mechanism are in the top secret. I cannot let the craftsmen of the Mojia Workshop intervene, and Ding Shuang and Ge Tong are still unable to rest during this period. Don't you want to learn the mechanism puppet technique? Then start tomorrow. Without your help, I will not be able to refine the most critical arrow box within one month." Chen Hai said.

"Arrow array box?"

"Yes, I have to seal the core components of the mechanical crossbow into a tight box, so that your sister can make the mechanical crossbow by herself if she gets a kind of crossbow - the drawings of the mechanical crossbow, I have to buy it for another purchase." Chen Hai shrugged.

"Can the drawings be sold to the Black Yan Army?" Su Ling was a little surprised.

The mechanical crossbow is a killing weapon that ordinary generals and soldiers can operate. The value of its drawings is far above the mechanical puppet beast that can only transport supplies. Su Ling thought that Chen Hai could not allow the secret of the mechanical crossbow to be leaked out.

"Why can't it be? At least foreseeable time, the Black Yan Army will not be the enemy of Juquanling." Chen Hai smiled.

"The Marquis has already led Hexi troops into Lichuan County with Hou Dong. Heyang County is fighting. Isn't the young master afraid that the Marquis will face off against the elite Black Yan Army? Are you not afraid that this mechanism will be unfavorable to the troops of the Marquis' Mansion in Zhaoyangting?" Su Ling asked.

Chen Hai spread his hands. Although Dong Shou was violent, the soldiers and horses in Hexi entered Lichuan County and did not come to compete for merit. The chances of fighting a tough battle with the Black Yan Army were very small. He was not worried that his uncle Chen Lie and the soldiers of Zhaoyang Tinghou's Mansion might encounter crossbows.

In order to prevent Ning Chan'er from cracking the arrow array box as soon as possible, so that the drawings cannot be sold at high prices, Chen Hai only used ordinary gold quenching iron to refine the arrow talisman array derived from eight kinds of Taoist seals, but the box body sealing the arrow talisman array penetrated into a certain amount of black fetal iron.

If an outsider wants to break the box and see the truth, he will inevitably destroy the inner arrow talisman array.

******************************

The transactions of gold-tempering arrows and gold-tempering mysterious soldiers, bulk herbs, spiritual beasts, bones, and weapon refining materials are very easy to be eyebrowed by other forces in Yanjing City; now Yanjing City is also very alert to the entry and exit of strange masters.

The two parties agreed to go directly to Juquanling to conduct transactions, and there is no need to go around Yanjing City to add another level of risk.

The appointment was soon, and Chen Hai took leave with Mojia and rushed back to Juquanling. The Mojia Workshop was chaired by Xue Cun and Ji Yuan, two young craftsmen in Mingqiao Realm. It was no problem to mass-produce primary organ beasts.

At the agreed time, the Black Yan Army sent two powerful Mingqiao realm masters of the high priest level to Juquanling for the appointment, but Chen Hai unexpectedly did not see Ning Chan'er.

Two high-ranking figures of the Black Yan Army climbed over Jueling on the northeast foot of Qintong Mountain. They also felt very distressed when they rushed to Juquanling because they carried a storage ring containing a large amount of trading materials.

A high-level storage ring that can store bulk materials requires consuming a large amount of true energy mana at every moment to maintain the space magic array. Even for late Mingqiao realm strong people, it is not easy to last for several days. You may need to stop two or three times in the middle to supplement the lack of true energy mana.

This is actually an extremely dangerous thing. Once there is a slight leak, perhaps a strong enemy may find traces in Qin Tong Mountain, and it will be difficult for them to escape the pursuit in this state.

And it is precisely such a risk that the Black Yan Army's desire for this group of excellent soldiers is more obvious.

Two high-ranking priests of the Black Yan Army took out piles of herbs, spiritual beast muscles, bones, black fetal essence, iron, red marrow copper and other objects from the storage ring. They rested in Juquanling for two hours to restore the true essence magic power, and then put 20,000 gold-tempering arrows and 1,000 gold-tempering spears into the advanced storage ring.

There are 20,000 gold-tempering arrows and 1,000 gold-tempering spears. They are not that large in size, but they are much heavier in weight.

Even if the high-level storage ring can reduce the weight by more than 90%, it is still a huge burden for the two late Mingqiao realms. They may need to rest more force on the way before they can enter Jiyang County controlled by the Black Yan Army.

Even so, the two high-ranking priests of the Black Yan Army stepped into the mountains north of Juquanling without hesitation.

The Black Yan Army does not need gold-tempered armor, but more sophisticated weapons, which also combines the meaning of Juquanling. After all, casting and forging of gold-tempered spears is much easier than fish scale gold-tempered armor, and the output is much higher.

However, the two high-ranking priests of the Black Yan Army did not mention taking away the crossbows of the mechanical crossbows. Chen Hai waited in Juquanling for two more days before Ning Chan'er rushed over.

Chen Hai was talking about things with Wu Meng, Ding Shuang and others at the Lingyun Pavilion on Juquan Lake in the northern cliff of Juquanling. Ning Chan'er was alone and flew directly from the other side of Juquan Lake.

Ning Chan'er's concave and convex body was covered with a slightly wide black robe, and her face was covered with gauze, making people unable to see her gorgeous face. Chen Hai saw that her robe seemed neat, but her breath was a little messy. Even through a layer of gauze, Chen Hai could feel that her soul was weak. He must have fought with someone on the way to Juquanling and suffered a lot of losses.

Su Ling was worried, Chen Hai frowned slightly and asked, "You won't have leaked your identity and lead the strong enemy to Juquanling, right?"

"If I want to lead the strong enemy to Juquanling, I won't delay two more days on the way," Ning Chan'er stretched out her hand and said indifferently, "Take the thing over."

Chen Hai asked Su Ling to return to her residence and took over the first mechanical crossbow that was trial-made.

The talisman array box was refined by Chen Hai during the Mojia Workshop, and the other crossbow parts were still cast from Juquanling. However, in the past two days, together with Zhou Jingyuan and others, they adjusted the precise parts before assembling the first batch of mechanical crossbows.

This trial-made mechanical crossbow mainly uses black fetal essence iron and a large amount of gold quenching iron, weighing more than 300 kilograms. It is still difficult for ordinary soldiers to operate on the battlefield, but Ning Chan'er picked up a fallen leaf and grabbed the crossbow arrow in his hand.
