This time, with Shen Kun's support for Juquanling, there are more than a dozen young disciples such as Shen Xiu and Zhou Qingyun, they are young, they have all cultivated in the Huanglongyuan Taoist Academy before, and they have cultivated to the middle and late stages of the Tongxuan Realm at the age of sixteen or seventeen, and even have stepped into the Soul Clearing Realm, it is inevitable that there will be arrogance and arrogance standing above all living beings, but after more than a month of tempering, they have matured a lot. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

At this time, they knew that since they were martial cultivators of the same realm, there was still a world of difference in strength, and although Shen Xiu and Zhou Qingyun had both stepped into the Spirit Breaking Realm, they were still not the opponents of those veterans of the Xuan Realm. Even if they can win one-on-one, the veterans have too much experience in teaming up, and they can still learn a lot of lessons in the unpredictable fierce battle.

Of course, Shen Xiu and Zhou Qingyun participated in the actual combat drill with the demon crocodile, and their growth was also extremely rapid.

During this period, every two or three days, Chen Hai would sneak into the bottom of the lake to fight with the demon crocodiles after recovering his true vitality, but he did not interfere at all in the defense and vigilance in Juquan Ridge, and handed them over to Wu Meng and Ge Tong to be responsible for training.

This kind of life, even Su Aya feels scared enough, I don't know when there is a leak in the cordon deployed by Wu Meng and Ge Tong, and it will only react if the demon crocodile is killed in the village, so many ordinary people will inevitably have a lot of casualties.

In the end, when Zhou Jingyuan took Chen Hai's name, and the spokesperson of the Tu family and the Fan family in Tongbei Mansion could no longer borrow the pill, this training was over, Chen Hai personally dived to the bottom of the lake, and dragged the corpse of the demon crocodile nearly thirty meters to the lake.

Even if this demon crocodile had been exhausted and scarred by Chen Hai and more than two hundred elite guards during this time, Chen Hai was able to kill the demon crocodile at the bottom of the lake, which still made Su Aya unable to believe what she had seen.

At the same time, in the late stage of the Spirit Realm, does Chen Hai really want to surpass Wu Meng and Ge Tong so much?

Could it be that this is the real strength of the Northwest Regions to choose the first place?

She waited for Chen Hai closely, Chen Hai entered the bottom of the lake and fought with the demon crocodile, she waited on the shore to help hold the armor, knowing that Chen Hai did not use the magic weapon, only with the frost quenched gold halberd, two days and two nights of fierce fighting, the demon crocodile was finally killed.

How tenacious is the vitality of the demon crocodile, everyone has the same vision, Chen Hai's strength can last for two days and two nights, is he still a human?

Taking Jiao Ji Pill is so miraculous, Chen Hai's physical strength can really be compared to Jiaolong?

Su Aya didn't know that in more than 50 days, Chen Hai had fought nearly 20 battles with this demon crocodile, that is, when he dived to the bottom of the lake for the nineteenth time, he had already mastered the complete true meaning of the countercurrent, even at the bottom of the turbulent lake, in the face of the murderous demon crocodile, he already had a crushing advantage.

However, Zhou Jingyuan wanted to cry without tears, if it weren't for the fact that Chen Hai was the Si Cheng of Tongbei Okura at this time, he could borrow a lot of resources, Juquanling would have been unable to survive and go bankrupt, and the extremely precious materials harvested from the corpses of the two demon crocodiles might not be able to make up for the consumption that lasted for nearly two months.

Juquanling owed a large amount of pills to the Tu clan and the Fan clan at this time, and borrowed an additional 600 quenched gold halberds, 200 pairs of quenching scale armor and two troop transport ships from Tongbei Beicang, which were almost exhausted, and they still needed to smooth out the account little by little......

Chen Hai didn't care, because when resources are developed, they must be used, and only by using them can they be turned into intangible strength.

In this battle, the two demon crocodiles that were killed, the materials that could be collected could make up for the consumption at most, and there was even a deficit, but except for the two hundred guards, whether it was personal or the strength of the battle array, it was a substantial leap.

And in terms of other resources, it's definitely worth it.

Kill the demon crocodile, Juquan Lake has no demon beasts to make waves, and it will completely open up the waterway communication with Tongbei Mansion to facilitate the transportation of bulk materials.

At this time, the ore, timber, tung oil, gum, medicinal materials and other products in the mountains near Juquanling and even west of Juquanling can be transported to Tongbei Mansion on a large scale, and a large amount of grain, conventional ironware, porcelain and so on can also be transported from outside the mountain.

Once this kind of large-scale material exchange is launched, more ordinary people can be settled and multiplied in the mountains west of Juquanling.

After killing the demon crocodile, in addition to opening a remote fishing port and hunting fish and beasts, building lake embankments and river embankments along the banks of the lake and many tributaries, and cultivating a large number of grain fields, at this time, tens of thousands of hungry people outside the mountain can be guided to Juquanling to settle. In the past, there were a large number of lakesides and river valleys around Juquan Lake that could not be reclaimed, just because of the monster crocodile, let alone fishing in the lake.

Juquanling wants to develop the resources of the western foot of Qintong Mountain on a larger scale, and it cannot afford the support of a large number of manpower.

Just like a large mine, it needs three or four thousand young and strong laborers, and now Juquanling even counts the old and weak women and children, there are only three or four thousand people, where is there so many young and strong laborers available?

Many of the mountains in the upper reaches of the Tong River are areas rich in gold and iron, but these mountains have been divided by other sect forces one after another, and Chen Hai has no way to reach out there to mine materials.

However, over the course of hundreds of years, the mineral rocks in these deep mountains have been eroded by the years, weathered into fine gravel, and eventually a large amount of gold and iron ore with a relatively high density will eventually accumulate in the silt at the bottom of the lake with the intricate terrain of the Tong River flowing into Juquan Lake.

These lake muds are actually placer raw materials that are easier to collect, and there are even many natural rare gold and iron precipitated at the bottom of the lake, waiting for the people of Juquanling to mine.

The deep mountains and old forests at the western foot of Qintong Mountain, although the resources are richer, but the roads are impassable, manpower is scarce, and many resources cannot be developed, but the treasure house of Juquan Lake is under everyone's eyes and noses.

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

After a simple transformation, a troop carrier becomes a sand mining ship, and soon a shipload of lake mud ore rich in gold and iron ore is dug up, and after several preliminary processes of washing and filtration, it is directly sent to the smelting furnace.

Because the composition of lake mud ore is too complex, it is much more difficult to smelt than ordinary iron and copper, and the smelting furnace even needs to smelt into a large flame gathering rune array to greatly increase the temperature of the smelting flame before the ore can be burned and melted.

If the smelted is only ordinary iron, the cost is too noble, but it is precisely the composition of the lake mud and mineral sand that is too complex, and the result is quenched iron.

Because the ore veins flowing through the source of the upper stream of the Tong River are fixed, although the composition of the lake mud ore is complex, it is very stable, and the composition of the quenched gold and iron is also extremely stable.

Watching a furnace of quenched iron directly cast into shape, but repeatedly forged to evenly distribute the internal components, Zhou Jingyuan touched the unpolished but already looked at the quenched halberds, quenched spears and quenched scale armor, and he was excited to shed tears.

Here, the cost of smelting quenched iron is more than ten times higher than that of ordinary iron, but it is less than a quarter of the price of quenched iron obtained by the sect lord and sect by the method of infiltration and smelting.

What a terrifying wealth is the rich mine of lake mud accumulated at the bottom of Juquan Lake at the end of the lake, which they will not use up for a hundred years?

At this time, Zhou Jingyuan was convinced that Chen Hai's choice of Juquanling was deliberate, and he came to this lake mud and sand from the beginning - those two demon crocodiles, where are they qualified to be compared with this lake mud and sand full of pits and valleys.

It's just that he doesn't know, how did Chen Hai know that this lake mud and mineral sand is so precious?

Chen Hai naturally does not explain to others the formation principle of alluvial placer deposits, which is not a profound knowledge on the earth, and geography will be learned in junior and senior high schools, but in Yanzhou, it is a geo-exploration science that no one knows, or only a very small number of sect lords monopolize.

Of course, Juquan Lake can be enriched with placer ore, and there must be a large number of gold and iron ore veins in the upper reaches, but nature is just a miracle to gather gold and iron ore to Juquan Lake.

Zhou Jingyuan knew too well the significance of their ability to smelt quenched iron on a large scale in Juquanling.

Compared with ordinary precision wrought iron, quenched iron has a leap forward in all aspects of performance.

Xuan Xiu's talisman spell or magic weapon, spirit armor, the defensive power is not unlimited, it is just an ordinary iron arrow, the penetration power is limited, and it is necessary to fire a salvo of hundreds of bows and crossbows to form a suppressive arrow rain, in order to pose a threat to the yellow-level protective spirit armor and shield at close range.

The quenched arrows made of quenched iron have seven or eight times the penetrating power of ordinary iron arrows, and if they are engraved with a dao seal that can increase their penetrating power, the power is even stronger.

The iron arm bow made of fine wrought iron could only shoot three or four hundred steps, while the two quenched iron arm bows made by Chen Hai with quenched iron before shot 1,500 steps, and the arrow momentum did not decrease slightly.

If it is replaced with a large bed crossbow and a car crossbow, it will have the power of breaking through the mountains and walls.

At the same time, the quenched gold halberd is a warrior used by martial arts cultivators in the Spirit Clearing Realm and even the Ming Aperture Realm, and the protection of the quenched gold shield and quenched scale armor made of quenched iron is far beyond the reach of ordinary precision wrought iron armor and iron shields.

It's just that the production of quenched gold iron is too scarce, Chen Hai cooperated with Li Xianghai to kill the Jade Dragon Mountain, and made the first contribution, so he was given a pair of quenched gold halberds and quenched gold scale armor;

But because of the vicious battle with the demon crocodile that lasted for nearly two months, more than 500 pairs of quenched gold armor borrowed from the Tongbei Northern Warehouse Branch were damaged, and it is no wonder that Zhou Jingyuan was so anxious to hang himself.

Now, don't worry that there won't be enough quenched iron to repair these armors, and after smelting a large amount of quenched iron, Juquanling will be able to create mechanical chariots and other weapons that can really charge on the battlefield.

The body made of precision wrought iron plates is extremely bulky and has poor defensive power, and it is replaced with quenched iron, which reduces the weight of the body by more than half, and the protection can be increased by five or six times.

At this time, the Juquanling foundry was mainly for the construction of armor for the northern Tongbei Okura, but the repair materials drawn by the Taiwei Mansion or the Xiyuan Army Governor's Mansion, precision wrought iron and rare gold and iron such as black iron, black sand gold, and red pulp copper were all separated, and they were sent to Juquanling to refine quenched iron by themselves with the momentum of seepage casting.

At this time, Juquanling can refine quenched gold iron on a large scale, and it is not enough to refine the fine wrought iron, and the Taiwei Mansion and the Xiyuan Army Governor's Mansion can accumulate rare gold and iron such as Xuantie, black sand gold, and red pulp copper, and then they can cast armor-piercing arrows that are more powerful and penetrating to make the powerhouses of the Dao Dan Realm tremble.

The casting of armor-piercing arrows does not have much technical content, but fist-sized Xuanfetal fine iron or black dust gold, mixed with other materials, is enough to refine a yellow-level high-grade spirit sword, but only two or three armor-piercing arrows can be cast.

The wolf-slaying sword given by Chen Haide's Mansion is a Xuan-level low-grade Xuan soldier, and the real black sand gold content in the black steel casting used is enough to cast more than a dozen armor-piercing arrows.

Juquanling monopolized the supply of armor for the Xiyuan Army at this time, even if the Taiwei Mansion and the Xiyuan Army Governor's Mansion supplied a small amount of rare gold and iron every year, but the accumulation of a lot of arrows could still cast a batch of armor-piercing arrows every year.

Zhou Jingyuan calculated that this side of the back mountain must be classified as a forbidden place, and all unrelated people are prohibited from entering and leaving.
