Chapter 971： Lu Feng's approach

You know, after Lu Feng broke through to the realm of the emperor, Ou Yezi's strength was promoted from the seventh heaven of the holy king to the third heaven of the emperor.

But the crossbow arrow that killed the sacred crossbow asked a warrior of the Emperor's Triple Heaven to carve the lines on it, and it could only carve a hundred in a day.

And a hundred sacred crossbows, for the battle of millions of troops, the effect is basically negligible.

Lu Feng had no idea that the difficulty of making this crossbow would be so great!

It is no wonder that even though the Cangchu Dynasty had such a big killer, it did not choose to expand its territory with this. It turned out that this crossbow arrow was too difficult to make.

Moreover, this is just an ordinary sacred crossbow arrow, if it is a special crossbow arrow aimed at the powerful, the difficulty will definitely be even greater.

With the current Nanyan Kingdom, it may not be possible to make it.

After pondering for a moment, Lu Feng looked at Ou Yezi and asked, "Is it possible that you can first make a mold, then melt the fine iron stone into molten iron, and inject it into the mold, so that the carved lines on it can form independently?"

"I have considered this method, but I can't do it at all."

Ou Yezi smiled bitterly: "The lines on the carved crossbow arrows will have huge energy fluctuations. This energy fluctuation mold can't bear it at all. Therefore, this method does not work."

"Does that mean that as long as the mold can withstand energy fluctuations, this method can be successful?" Lu Feng asked immediately after his eyes lit up.

"This……"

Ou Yezi thought for a while, and said: "It should be no problem in theory, but it is too difficult to make ordinary molds with hardness that can withstand such energy fluctuations, even if the array is arranged, it is useless."

"The formation is definitely useful, but it depends on the formation."

With a smile on Lu Feng's face, he said: "Let me try, maybe I can succeed."

But Ou Yezi smiled bitterly, shook his head, and said: "Your Majesty, the minister understands your plan to use the profound formation to increase the hardness of the mold.

But the possibility of success in this way is too small, because the kind of energy fluctuations that engrave the crossbow arrows must have real energy as a primer. "

"Even if your formation is formed, but there is no real energy as a primer, it is impossible to make the lines carved on the crossbow arrow useful, so..."

Frowning slightly, Lu Feng didn't expect to have any requests.

But after thinking about it, he still said: "This is the only way at the moment. It must be tried."

"The minister follows the decree."

Ou Yezi understood Lu Feng's thoughts, and immediately responded, and took Lu Feng to the place where the crossbow arrows were made.

Soon, Ou Yezi took Lu Feng to the place where he made the crossbow arrows.

The four walls here are all depicting the formation method to ensure that there will be no accidents.

Lu Feng saw that there were already a lot of Miserable Crossbow Arrows around, and there were still many craftsmen carving the lines on the Crossbow Arrows.

The speed is just as Ou Yezi said, very slow.

When these refiners saw Lu Feng, they saluted together: "Long live my emperor, long live long live."

"Flat body."

"You wait to retreat first."

"The ministers follow the order."

Everyone immediately listened to Lu Feng's order and left here quickly.

"Your Majesty, the fine iron stone used to make the sacred crossbow arrow only needs the most common fine iron stone, so I use the thousand-year fine iron stone to make the mold."

Ou Yezi took out a mold from the side and handed it to Lu Feng. The mold was engraved with lines. You only need to melt the ordinary iron stone into molten iron and pour it into it to form a perfect crossbow arrow.

But this is an imaginary situation, this place simply can not be done.

Ou Yezi pointed to the other side, where there were many broken molds. He sighed lightly, and said, "That's because I planned to use such a failed and damaged mold before, and I can't withstand the energy generated after the crossbow arrow is formed."

Lu Feng did not answer, but carefully looked at the pattern on the mold, and then said after a while: "This pattern is an array pattern. It seems that the person who made the Sacred Crossbow was a genius and used the hardness of the fine iron stone to make the arrow. , Portray the formation, and then use the huge energy produced by the Mie Sheng crossbow to urge the formation on the crossbow, which can cause huge damage."

"exactly."

Ou Yezi said: "The minister also discovered this, so carving the lines on each crossbow arrow is equivalent to depicting a formation, so the production is so difficult."

"Since this is the case, that is to say, as long as the mold can withstand the energy impact generated when the crossbow bolt is formed."

Lu Feng's eyes moved slightly and said, "Let me try."

"Condensation!"

With a low drink, Lu Feng quickly typed out three profound texts with both hands and landed on the mold in his hands.

"Om!"

There was a hum from the mold, and a wave that was visible to the naked eye turned away, and finally merged on the mold.

"The hardness has indeed increased a lot."

Ou Yezi felt the change in the mold at once, but after a little indulged, he said: "But this will not allow the martial artist to embed in it, and it will not be able to use Zhen Qi as an introduction to the pattern forming on the crossbow arrow. The crossbow arrow cannot be successfully produced. ."

"Don't worry, you first try to see if a mold with this hardness can withstand the energy impact of crossbow arrow forming." Lu Feng said to Ou Yezi.

"The minister follows the decree."

Ou Yezi immediately took the mold and started making crossbow arrows.

After a while, he poured molten iron melted from fine iron stone into the mold.

Soon, the molten iron gradually solidified, forming the appearance of a crossbow arrow, and the lines on it were clearly visible.

But it lacked true qi as a primer. Ou Yezi looked at Lu Feng, and when he was about to speak, Lu Feng moved his hand and another mysterious text appeared in the sky, saying: "Pour your true energy into this mysterious text. "

"Yes!"

Ou Yezi immediately poured himself into Xuanwen as Lu Feng said.

"go with!"

Lu Feng controlled this Xuanwen and quickly dropped, landing on the crossbow arrow in the mold.

"Om!"

A huge humming sound came from inside the mold, and the crossbow arrow sent a huge energy and began to impact the mold.

But at this moment, a flash of fluorescence flowed on the mold, completely blocking this energy.

"Crack."

After a slight noise, a crossbow arrow fell out of the mold, and fell to the ground with a'ding'.

"Success!"

When Ou Yezi saw this crossbow arrow, he immediately saw that this crossbow arrow was exactly the same as the one he had made before, and it was far faster than before.

He took the crossbow and looked at it, and said, "Your Majesty, your method is indeed useful, but..."

After looking at Lu Feng, Ou Yezi said: "In this way, you need to use Xuanwen every time, this..."

The words were not finished, but Ou Yezi's meaning was obvious.

Lu Feng is not the refiner of the Nanyan Kingdom, but the emperor of the Nanyan Kingdom. It is impossible for him to stay here and let him play a mysterious text every time he makes a crossbow.

This is impossible.

There are so many things in the kingdom that need to be handled by Lu Feng, not to mention that there may be wars on the front line at any time, and it is impossible for Lu Feng to stay here to make crossbow arrows.
