"Master Luban, what's the problem?" Lu Zihong asked a little nervously.

If the template doesn't work, then he won't be able to get a lot of Thunderstorm Heavy Crossbow arrows, and the Thunderstorm Heavy Crossbow will become a useless ornament.

This has a great impact on the combat effectiveness of his army!

"Returning to Your Majesty, although the minister can make a template, the engraving in the template will gradually be eroded by molten iron as the number of arrows made increases, and at most ten crossbow arrows of thunderstorm heavy crossbows will be deformed, thus losing its effect." Lu Ban said.

Lu Zihong frowned slightly.

The materials used to make the templates are all ground-level materials, which are very precious, and if each template can only make ten crossbow arrows, the cost is too high, and it is not at all affordable for the Northern Qin Kingdom.

"Is there no other way to change that?" Lu Zihong asked after groaning.

Luban fell into deep thought.

After a while, he said: "There is a way, but the minister needs the help of a formation mage who is at least a heaven-level lower grade, but a heaven-level low-grade formation mage ......"

With a wry smile, Lu Ban said: "This level of formation mage, unless it is a dynasty, or it is impossible to find it!" And even if we find it, we can't let him keep it a secret for us, once the news spreads that we can use the template to make crossbow arrows for the Thunderstorm Heavy Crossbow on a large scale, it is impossible for the two dynasties in Beizhou to let us go. ”

"After all, the thunderstorm heavy crossbow arrows in their dynasty were also made one by one by gathering a large number of low-level craftsmen, and there was no template at all!"

"So ......"

"Alas!"

Sighing helplessly, Lu Ban said: "We can't find a heaven-level inferior formation mage for help at all!" ”

"Hahaha."

Lu Zihong laughed loudly when he heard this, and said, "If it is other requirements, I may really have no choice, but the heaven-level array mage ......"

After a pause, Lu Zihong smiled and said, "Master Luban, look what this is!" ”

As he spoke, his soul energy surged, and in an instant, he carved a heaven-level inferior formation in front of him!

"Soul Condensation Array, Heaven-level Array Mage?"

Lu Ban was stunned for a moment, and then exclaimed: "Your Majesty, you ...... You're actually a Heaven-level Array Mage? ”

As a high-level craftsman, Lu Ban naturally knew that the symbol of a heaven-level array mage was to condense the formation with souls.

But he never thought that Lu Zihong would be a heaven-level array mage!

You know, Lu Zihong is only eighteen or nineteen years old!

"I'm just a little talented in formations."

Lu Zihong smiled, it was naturally impossible for him to tell Lu Ban that he had used the Formation Mage Secret to become a Heaven-level Array Mage.

Lu Ban didn't know what to say for a while when he heard this.

Eighteen or nineteen-year-old heaven-level array mages are not very talented? This is simply a gift, and even this talent can be called a demon!

"Master Luban, now you can talk about your solution." Lu Zihong mentioned.

Lu Ban nodded and informed Lu Zihong of his method.

The method is very simple, just arrange a reinforced formation on the made template.

However, because the low-level reinforcement formation is easy to affect the engraving on the template, if it causes the fusion of formation energy, the template will be wasted, so it must be a high-level reinforcement formation.

The method given by Lu Ban was the Heaven-level Inferior Reinforcement Formation that he had obtained by luck when he traveled to the continent before, which could ensure that it was completely separated from the engravings on the template, and there was no energy fusion.

"Your Majesty, this is the arrangement method of that heaven-level inferior reinforcement formation."

Lu Ban handed a jade cylinder depicted with mysterious patterns to Lu Zihong.

Lu Zihong immediately checked the contents inside, it was indeed a heaven-level inferior reinforcement formation, and it was not too difficult, he only took more than half an hour to fully comprehend it.

Then he began to lay out the template, but he didn't use the Soul Condensation Array to set up the array.

Because the formation used to lay out the soul condensation array can only exist for a short time, and cannot be retained permanently, only the formation engraved on the template can be retained forever.

Fortunately, Lu Zihong is a heaven-level mid-grade formation mage, and it is easy to arrange a heaven-level low-grade formation, and it only takes half an hour to get it.

"Great."

Looking at the template depicting the formation, Lu Ban's face was full of excitement, and he said, "Your Majesty, I'll try to see if the crossbow arrows made from the template can work." ”

Saying that, he used his craftsman's skills to turn a piece of iron the size of two palms into molten iron, poured it into a groove in the stencil, and then condensed the molten iron to make it quickly shape.

A few moments later, a crossbow arrow carved with arcane patterns appeared in the groove.

Lu Ban waved his hand, and the crossbow arrow flew into his hand, and then he took a thunderstorm heavy crossbow to the head of Yaochuan City for testing.

"Let's get started!"

At the head of the city, Lu Zihong looked at the thunderstorm heavy crossbow in front of him and said.

"Yes!"

Lu Ban answered, then took a deep breath and urged the thunderstorm heavy crossbow.

Lu Zihong is also staring at the Thunderstorm Heavy Crossbow, whether this method can be successful is related to whether he can obtain a large number of Thunderstorm Heavy Crossbow Arrows, which is very important to him!

"Zizizi!"

With the slight sound of electricity, the thunderstorm heavy crossbow glowed with silver light, and then with a 'boom', the crossbow arrows placed on the side were fired.

Then I saw that the crossbow arrow quickly absorbed the thunder energy in the aura of the surrounding heaven and earth in the process of breaking through the air, and when it landed, it suddenly detonated the thunder energy, making a loud noise.

"Hahaha, it's done!"

Lu Zihong was ecstatic, the success of this crossbow arrow meant that his template idea was no problem.

In this way, he will be able to obtain a large number of crossbow arrows, and make his three thousand thunderstorm heavy crossbows powerful again!

What's more, the success of the template idea can be applied to other things, which is a good thing for the whole kingdom!

"Whew!"

Lu Ban took a deep breath and muttered: "The craftsmen of the Wuling Continent have a long history, but they have never had a templated idea, and Your Majesty is only eighteen or nineteen years old, but he can already create such a unique insight, he is really a god!" ”

This made Lu Ban's eyes look at Lu Zihong even more admirable!

Lu Zihong heard Lu Ban's low voice, and he looked a little embarrassed.

What kind of god man is he, he just stands on the shoulders of those giants in his previous life.

It's just that he certainly can't say that.

He looked at Lu Ban and said, "Master Lu Ban, let's hurry up and continue to make templates, only a large number of templates can produce a large number of crossbow arrows, which is very important for the kingdom!" ”

"Yes!"

Lu Ban took the order.

Then Lu Zihong took Lu Ban back to the treasury and tried his best to make the template.

At first, it took the two of them half an hour to make a template, but when they became proficient, they were able to complete a template in just half an hour.

In just over four hours, the two of them have already produced thirteen templates!

Lu Zihong originally intended to continue the production, but the urgent news brought by Ji Handle made him have to stop the production of the template immediately!
