With Langdon's drawings, both the blacksmith and the alchemy workshop were progressing well, and the things Langdon needed were quickly produced from them one by one.

The first good is the winch, several pure iron winches quickly replaced the original copper winch, after all, the texture of copper is not as hard as iron, after several drawbridge ups and downs, there has been a little deformation, and the iron will never have this problem.

Then, the chains made of interlocking oval iron rings, as thick as an arm, replaced the blackwood bark ropes that Langdon had spent a lot of time making, of course, those ropes were not discarded, and were still useful in other ways.

On the day of the change, almost all the townspeople came to watch, and they couldn't help but let out a cheer when they saw the three suspension bridges being lowered at the same time with the clattering sound of iron clattering.

In fact, this thing is no different from the previous black wood bark rope, but the visual effect of the iron giant lock is far beyond the rope, and with the gurgling "BGM", it naturally gives people a sense of security.

Followed by the Iron Claw Hook, the first time old Hetis received a special request from the lord, but he was so energetic that he almost never left the casting room during this time, eating and sleeping in it.

In the end, he did succeed, and he overfulfilled the task - the iron claw hook he created can be contracted many times, and the tightness of the grasp can be adjusted, and the tightest gear can be directly contracted into a fist, which is not only a grasp, but also a weapon.

This surprised Langdon, and he began to think about giving the old black dwarf a sense of recognition, which would not only increase the loyalty and sense of belonging of the old black dwarf, but also serve as an example for others.

Compared to the blacksmith shop, there were some minor troubles on the alchemy workshop.

According to the method given by Langdon, Parek successfully purified the water jade ore to a purity of more than 90%, and even with his own efforts, the purity exceeded 95%, which also let him know that the water jade ore actually showed an almost transparent texture at such a high purity.

However, the next process of pulling the ores and turning them into discs only a few centimeters thick went wrong.

Parek experimented for a long time with his apprentice's assistant, but he still couldn't do it, and caused several pieces of jade ore to break into several pieces.

This made Parek afraid to continue, so he had to invite Langdon to come.

Water jade is not a metal, it is more like jade and something like that, so there is no way to deal with it with the forging method, only alchemy can be used.

Such a problem is a problem for Parek, but not a problem at all for Langdon.

It took him a day to process all the water jade ore, but fortunately, Parek was quite good and took care of the most troublesome purification process.

Then, when Langdon left the alchemy workshop again, the only person allowed to give him a hand and watch Parek looked at him with admiration.

When the gap between two people is not large, the lagging side tends to be jealous, but when the gap between the two is so big that it is completely impossible to catch up, the emotion generated is worship.

After a few more days, Langdon left the town of Far Hope with a well-prepared team.

This team includes Langdon's strongest men, Goblin Knights and Lizardmen Spearmen.

In addition, there are fifty of the most powerful people in the territory, half of them are those bear goblins, and they have the hooks and cables that McCann led the troops to the city with the captured hooks on their bodies, but the heads of the hooks have all been replaced with iron claw hooks, and Zhu Lingqi has personally led them to practice the use of this iron claw hook in the past few days, and now they have basically mastered it.

In addition, there were fifty lizardman archers and hundreds of other men, and the whole team numbered more than five hundred, so they carried a large number of materials and utensils, and marched towards the Blackwater River.

Langdon chose to settle somewhere else, the place where he had dug up the direct flow entrance that he had derived.

Once there, Langdon gave the order, and the people immediately got busy.

The soldiers stood guard along the Blackwater River, while the workers separated them and worked close to the Blackwater River.

They're setting up a stage.

The planks were placed in the place where they should have been, and soon, large wooden platforms several meters high were erected.

A total of ten platforms, located on both sides of the Heishui River, after the construction is completed, someone will climb the platform, and then other materials will be sent up one after another.

Clusters of flames quickly ignited on each platform.

This time Langdon didn't bring a dark elf, among all the races with dark vision, the dark elf is one of the few owners of infrared vision, which is much more powerful than ordinary dark vision, but the disadvantage is also very obvious - fear of light.

Other underground races don't like light either, but they can barely adapt to it, but the dark elves and the light are simply mortal rivals, the light can not only make the dark elves unable to see things at all, the slightly stronger light can even directly blind their eyes, and, under the light, the strength of the dark elves will be greatly reduced, this reduction is hard, no matter whether the dark elf closes his eyes or not.

And this time, Langdon wants not only light, but also strong light!

Fires were lit on each platform, forming clusters of light in the dark environment, but this light was still too weak for the Heishui River, and it was completely swallowed before it could not even break through one meter below the surface of the Heishui River.

Of course, Langdon knew this, so after the fire was lit, large disc-like things were sent to the high platform—the jade ore that Langdon had processed.

Or it's more appropriate to change the name, Mirror.

This is what Langdon has to do, originally there was no water jade ore, and he still wanted to get some sand or something to refine by himself, but the trade with the Hoflan family allowed him to save this step.

Everyone on the stage had a mirror made of water jade ore in their hands, and then listened to Langdon's command.

"You, to the left, yes, right there, put your hands up to your chest, so stop. ”

"You take a step to the right, and he takes a step to the left, and his hands are raised above his head. ”

"You ......"

"Okay, now get ready, I'll shout to start, you guys just turn over the things in your hands, just like the previous drill, understand?"

After commanding the people on the stage, Langdon gave Zhu Lingqi another look, and the military master wearing a robe and wearing a double sword with an explosive body said with her unique two-dimensional three silent lines: "Everyone, listen to my orders and prepare!"

With a uniform voice, several teams quickly got ready.

Langdon nodded secretly, the professional is different, the trained soldiers behave differently, and at the same time, he has already exhaled and opened his voice, "Start!"

Swish!

Actually, there is no sound here, but anyone who sees this scene will definitely have this sound in their mind.

Swish!

All the mirrors flipped at the same time, and more than 100 rays of light shone out through the mirrors, and then converged in the air, and finally, pierced deeply into the Black Water River!

Darkness, pierced!
