Chen Hai went to Jiujun Island this time, and he didn't know how many days he would have to delay, and there were some things that needed to be done first.

After the Demon Chariot has enhanced the thickness of its armor, installed the Wind Flame Power Box, the drive steering parts, and the super heavy crossbow, heavy bore crossbow and other vehicles transformed into a heavy Heavenly Demon Chariot, the offensive and defensive will be integrated, and the combat effectiveness will be greatly improved.

And each set of Wind Flame Power Box is equivalent to a mid-to-high-grade magic weapon of the Xuan Rank, and its core prohibition cannot be split to divide and cooperate, and the refiners of the Ming Realm can only refine one piece a year.

At this time, Chen Hai added up the craftsman battalions in Quyan Valley, the northern foot of Dongdu Mountain, and Beiling Ying, with a scale of 4,000 people, but there were only thirty-six craftsmen (refiners) who cultivated above the Mingqi Realm, which meant that they didn't do anything, and they could only successfully transform thirty-six heavy Heavenly Machines Demon Chariots in a year.

However, even if the demon chariot is dragged on the battlefield with a spirit horse to form a traditional car formation, it will be subject to a lot of restrictions, but the combat effectiveness may not be much weaker, the most important modification in the early stage, in addition to enhancing the armor, adding super heavy crossbows, heavy crossbows and other vehicles, the effect will be more obvious.

More importantly, it is the Beilingsai garrison (Black Wind Army) that needs to train and adapt to new tactics of riding on chariots, riding on foot and combining chariots and steps.

In the past, Beilingsai focused on casting fixed stone-throwing crossbows, and Chen Hai asked that during his temporary absence, the craftsmen and battalions in the three places would cast more dragged heavy-duty stone-throwing crossbows.

As long as the weight of the towed heavy stone-throwing crossbow does not exceed 20,000 catties, it can be driven by the wind array box to move quickly in open terrain, and the improved wind array box is only equivalent to a yellow-level medium-grade magic weapon, and its core forbidden spirit realm refiner can refine it, and it is possible to create hundreds of bodies within three months.

Elite warriors can't fight against elite demon soldiers at all without relying on war horses, but Beilingsai can only make up 5,000 elite cavalry at present, and more infantry warriors want to participate in field battles, and the spear phalanx is a good way, and the craftsman battalion needs to cast a batch of heavy bladed black iron spears that are seven or even ten meters long to organize training.

However, all this has further increased the demand for Xuanyang refined iron.

The veins of Xuanyang refined iron are distributed a lot in the Xingheng Domain, but the content of Xuanyang iron ore is very small, such as several veins found in Quyan Valley and the northern foot of Dongdu Mountain, the content is less than one thousandth, which means that for every tens of millions of catties of ore mined, only less than 10,000 catties of Xuanyang refined iron can be smelted.

Even if the Eastern Capital City is built and mined at the northern foot of the Dongdu Mountain, to reach the scale of 10,000 catties of Xuanyang refined iron per day, it will also need to use two or three hundred thousand strong laborers, and the Eastern Capital City obviously cannot provide so many strong laborers at this time.

Chen Hai temporarily gave up the mining of the ore veins in Quyan Valley, transferred ten coiled blade mining vehicles and flame gathering furnaces to the northern foot of Dongdu Mountain, and also designed rail mine cars, hoping that within three to five months, only 50,000 or 60,000 strong laborers could be used to increase the daily output of Xuanyang refined iron to about 20,000 catties.

At present, Beiling Sai has two million Xuanyang Heavy Blade Arrows in stock, and if three hundred Xuanyang Heavy Rifle Crossbows are fired in a salvo, the effort of the two teas will be consumed.

Although theoretically, if all twenty Xuanyang Heavy Blade arrows were shot, it would make an elite Rakshasa Blood Demon lose its combat ability, but on the ever-changing battlefield, in order to form a barrage of arrow rain barrage suppression, it may take two hundred or more Xuanyang Heavy Blade Arrows to eliminate an elite demon soldier.

Therefore, one of the key points of the follow-up work of Beilingsai is to continuously increase the reserves of Xuanyang Heavy Blade Arrows, which is the fundamental guarantee for the Black Wind Army to go out of Beilingsai and fight with the elite demon soldiers.

After arranging all these tasks, Chen Hai delayed for almost half a month, and then entrusted the affairs of Beilingsai and the northern foot of Dongdu Mountain to Jiang Yuwei, Sha Tianhe, Zhu Mingwei and others, and he took Jiang Zhen, Yang Yin and others to go out to sea from Quyan Valley and go to Yang Fan on Jiujun Island.

The left ear also appeared directly in Quyan Valley, and boarded Chen Hai's ship, the Xuanlei wreck.

At this time, the Blood Cloud Wasteland has been occupied by hundreds of millions of demons, and Yanzhou is a foreign land with a lower level than the Xingheng Domain, even if the Xuanyuan Upper Hall is still guarding against the remnants of the Liuyang Palace not being completely extinct, but it will not think that the many Heavenly Realm powerhouses who fled into the Blood Cloud Wasteland with the prince Shang Que back then, who else can be alive.

And the Xingheng Domain is vast, not only the three kingdoms of Chong, Yue, and Tiannan, Zuo Er occasionally takes a boat as an overseas casual cultivator, and only returns to the cultivation of the first realm of the heavenly position, as long as the Dragon Ding and the Jade Void Temple do not appear, even if the news spreads, it will not arouse suspicion.

Through the opportunity created by Chen Hai, after Zuo Er ventured back to the Xingheng Domain, he has been living a life like a ground mouse, and this time he left the Demon Deer Ridge with heavy treasures such as the Dragon Ding and the Jade Void Temple, and naturally he was not willing to stay in the cabin without coming out to breathe, which was not conducive to his recovery of cultivation.

Of course, Chen Hai agreed to the appearance of the left ear, and also hoped that the left ear could directly participate in the restoration of the Xuanlei wreck.

Zuo Er, as a powerful Heavenly Monarch in the Liuyang Palace in the past, although it is said that his strength has not recovered at this time, and he is only the cultivation of the first realm of the Heavenly Rank, but his attainments in refining weapons are something that the so-called refining masters of Wanxian Mountain can't catch up with.

Even if Chen Hai secretly handed over the array weapon of the Heaven Xuanlei Great Array to his left ear for repair, he would definitely not be able to hide the ears and eyes of the old foxes such as Jiang Zhen and Yang Yin.

The Heavenly Machine Prohibition that Chen Hai is good at refining is mainly the Xuanbing Spirit Sword below the ground level and above the heavenly level, and he currently has a total of two Reverse Thunder Halberds and Qingsha Sword, not to mention repair and refine.

Although the most critical Dao weapon-level central array weapon of the Heaven Destroying Thunder Array was slightly damaged, who would believe that he had repaired it with his own hands?

And Jiang Yin was not good at refining weapons in the sect, if he asked the Heavenly Rank Realm True Monarchs who were good at refining weapons in Wanxian Mountain to repair this Dao-level central array weapon, the merits collected by the sect would probably be exchanged for a thousand black cunning horses, not to mention the repair costs of the other eight Heavenly Rank Array Weapons that were quite seriously damaged.

In order to repair the Wanyou Xuanlei battleship, Chen Hai also put a lot of thought into it, but when it came to the Dao weapon level, it was like talking to Xia Worm, which was not at all something that he, Shen Fumin and the others could understand.

At the beginning, Chen Hai had thought about dismantling all the array weapons of the Wanyou Xuanlei Battleship and transporting them to Wanxian Mountain to repair them, but when he heard the terrifying offer, he finally just gritted his teeth and dismantled the floating array and transported it to Wanxian Mountain for repair, preparing to build a floating battleship!

Now Chen Hai directly let his left ear appear and participate in the repair of the Xuanlei remnant, which can make Jiang Zhen and Yang Yin not think much about it.

"This Xuanlei ship is a good thing, if I am not mistaken, this should be the ship of a sect elder of the Immortal Sect in the Fusang Sea in the past. That Thunder Zhenjun is also a fourfold cultivation of the Heavenly Position, but the Immortal Sect is already poor and sour, and the time to become a climate is short, so naturally it can't create a higher-level Dao weapon. Retreating to the second, they took the primary-level Dao weapon of the Heavenly Pagoda as the core, and formed a large array with other magic weapon arrays, which was to give full play to the strength of the third-order Dao weapon, which could be regarded as a rather clever means. It's just that the Lei Yangzi you met is suspicious by nature, even the direct disciples don't let him have the slightest opportunity, and he has to control the entire Heaven Xuanlei Great Array with one person, so he can only exert three or four percent of the power of the entire Great Array. Otherwise, you wouldn't have been able to succeed so easily!" Zuo Er and Chen Hai sat back in the cabin, analyzed the pros and cons of the Xuanlei Ship with Chen Hai, and said.

Chen Hai thought about the situation at that time, and it was indeed the case.

The Xuanlei ship has three magic arrays, in addition to the most fundamental Xuanlei Array, there are also water resistance arrays and floating arrays, and the formation mages on the Xuanlei ship at that time seem to be responsible for controlling the water resistance array and the floating magic array, except for Lei Yangzi himself, there is indeed no one else involved in the Xuanlei Thunder Array.

Although the Heavenly Realm True Monarch can divide hundreds or thousands of divine consciousness imperial objects and imperial weapons, Lei Yangzi alone can control the entire large array, but no matter how powerful a person's divine soul is, it is limited after all.

"I'm not by your side in the future, except for you, there is no one around you who can sacrifice the core of the Heavenly Tower, and you can't always be with this broken ship. You can dismantle the Heavenly Tower and use it as a simple thunder weapon, and you can avoid the use of forced sacrifice now, and the other array weapons, with some minor modifications, can still be used to form a ban-level magic circle!"

"Without stepping into the Heavenly Realm, you can use a sacrificial Dao weapon?" Chen Hai asked suspiciously.

"The reason why a Dao weapon is a Dao weapon is that it has not touched the origin of the Great Dao, and it is impossible to understand the internal formation prohibition at all, so naturally it cannot be cultivated—and you have already touched the origin of the Great Dao, you are already an existence in the quasi-heavenly realm, how can it be compared to other vulgar Dao fetuses who have not touched the edge of the Great Dao?" said with a snort in the left ear, At that time, not only can the Xuanlei Array's Xuanlei Array be activated separately, but you will use the Heaven Destroying Tower to join in and form the completed Heaven Destroying Thunder Array, and the power will be multiplied, making strong enemies unable to defend against it, which can also be regarded as a means for you to win by surprise in the future!"

"......" Chen Hai didn't expect this kind of operation.

"While I am repairing this Heavenly Tower, you are refining, my strength has not recovered, and when the time comes, I need you to help me, so that it is possible to suppress that Qin Chuan!"
