Ling Yun touched his head, thinking if he was too simple, it was a bit difficult to ride a tiger now.

Yang Xiao and Fan Yao looked at the sect leader's face turning blue and red, they didn't know the depression in Ling Yun's heart, and they looked at him expectantly, as if they were waiting for the sect leader to show them a miracle.

Ling Yun looked at the three raw materials, his brain kept searching for information, recalling the knowledge he had learned, and what came to his mind was a piece of precision processing equipment, a complete production line, and a production process.

Ling Yun's mind became more and more chaotic, and beads of sweat began to appear on his head.

The production of huo is the biggest reliance on solving the dilemma of Shaolin Temple this time, and all plans are disrupted at this moment.

Relying solely on this group of rabble martial arts masters, Ling Yun had no confidence in whether he could resist the 100,000 yuan army until the reinforcements of the Blue Winged Bat King Wei Yixiao arrived.

Yang Xiao saw that the sect leader's face changed on the spot, and he was obviously hesitant, so he spoke:

"Sect Master, are you worried that the lethal power of firearms is too great and goes against the peace of heaven?"

When Ling Yun heard this, the fire suddenly rose from his heart, what is too big? I'm worried that the power of the production is too small!

After all, in the production process of huo medicine in the Yuan Dynasty, the power of the explosion was too small, and most of the firearms made could not even be worn through the heavy armor and wooden shields of the army, and the greatest damage to the body was the impact of a part of the explosion and the burning damage caused by the sparks scattered after the explosion ignited the clothes.

But such damage did not cause much trouble to the heavily armed regular army, which is why these dynasties were almost useless in warfare.

Too small?

Wrong!

Ling Yun suddenly had a flash of inspiration in his mind, and he couldn't help but want to slap himself twice.

My thinking is still too narrow.

When I first prepared to make HUO medicine into a thermal weapon, I always had the lethality of modern HUO medicine in my mind.

But he didn't take into account that his use of the modern huo medicine ratio in the Yuan Dynasty era was already a huge leap and progress.

There is no modern equipment and technology in time, but as long as the ratio is changed, the power of the HUO medicine produced is absolutely not the same as the current HUO medicine of the Yuan Dynasty.

Ling Yun figured this out and immediately became happy.

Turning his head, he called Yang Xiaofan Yao to his side, and began to explain to them in detail the configuration ratio and production process of HUO medicine.

After Yang Xiao and Fan Yao listened, the three of them began to deal with the three kinds of raw materials separately according to Ling Yun's arrangement.

It didn't take long to carefully process the three materials in front of him.

Three piles of raw materials were piled up in front of the three of them.

The three of Ling Yun stretched, looked at the mountains of materials in front of them, and smiled at each other.

Ling Yun instructed the two of them to mix the three materials strictly according to the proportion, and one of them turned around and walked out of the firewood room.

After Ling Yun left the firewood room, he looked around, and finally walked to the left hand wall, pulled out the dragon slaying knife from behind his back, and pried a wall tile out of the wall.

After checking the wall tiles, Ling Yun determined that this wall tile was the marble he needed.

So he held the wall tiles in his left hand, and with the dragon slayer knife in his right hand, he began to cut the wall tiles.

The dragon slaying knife flew up and down in front of his eyes, and the extremely sharp blades kept flying on the wall tiles like cutting tofu, and the stone chips flew everywhere.

After a while, the wall tile in Ling Yun's hand had been cut into a fist-sized ball.

Then he used the tip of his knife to make a small opening in the top of the stone ball, hollowing out the inside of the stone ball.

Then he remembered it over and over again, and with his memory, he carved deep grooves one after another with a blade on the outer surface of the stone ball.

Finally, Ling Yun looked at the stone ball in his hand with satisfaction, nodded, and walked back to the firewood room.

Yang Xiao and Fan Yao watched the sect leader walk back with a stone ball, and they were puzzled, they didn't know why the sect leader went out and got a stone ball.

And the three materials have been perfectly mixed by the two according to the requirements, turning into a pile of gray powder.

Ling Yun grabbed a handful of powder with his hand, looked at it carefully, and confirmed that the proportions were correct.

Then the powder is carefully packed into a stone ball, a piece is torn from the clothes, kneaded into a strip of cloth, and the strip of cloth is dipped into the kerosene lamp on the stove on the firewood room, and the strip of cloth is wrapped in a layer of kerosene.

Then Ling Yun carefully stuffed the strip of cloth into the stone ball, leaving a section on the outside of the small opening.

Ling Yun beckoned Yang Xiao and the others to follow him out of the firewood room, dug a piece of red mud under the steps at the door, and tightly sealed the mouth of the stone ball.

Looking at the primordial shou thunder made in his hand, Ling Yun looked forward to the power of the shou thunder again.

The three of them flew up, got on the roof of the firewood house, looked around, and found that there were almost no people in the entire Shaolin Temple, thinking that Kong Zhi took everyone to the mountainside to defend.

So Ling Yun saw that the martial arts arena built before on the right side was spacious enough, so he took the two of them to perform light skills, and their figures flashed, and they had already come to the high platform of the martial arts arena in a vertical leap.

Ling Yun carefully placed the shou lei he made himself in the middle of the high platform, pointed to a mountain rock fifty meters away, and motioned for Yang Xiao and Fan Yao to retreat behind the mountain rock.

The two of them hid behind the rocks according to Ling Yun's instructions, and they didn't dare to look at it.

Seeing that the two of them were hiding, Ling Yun took out the fire fold he had taken in the firewood room from his arms and lit it.

Then he bent down and lit the strip of cloth on the stone shou thunder, hurriedly performed light skills, turned around and flew behind the mountain stone to hide with Yang Xiao and the others, put his hands in his ears, and blocked the ear holes.

Seeing that Yang Xiao and Fan Yao were unclear, they looked at each other with a puzzled expression.

The three of them squatted for a long time and found that there was no movement.

Ling Yun also felt strange, could it be that there was something wrong with the shou thunder he made?

So they took their hands away, and the three of them looked at the square together.

Unexpectedly, before the three of them poked their heads out, suddenly there was a loud noise in the square, like a spring thunder in the flat ground, which scared the three of them and almost jumped up.

A gust of hot wind blew over the heads of the three people, and only the hair of the three people blew around.

After the hot wind passed, the three of them stood up and looked into the center of the square.

I saw a big hole about three meters in diameter in the middle of the high platform built of solid wood in the square, and countless fine stones were inlaid in the stands around the square, and the edge of the big hole was still emitting black smoke.

Although it was the first time for him to make a primitive shou thunder, when he saw the scene in front of him, Ling Yun's expression was quite calm because he had already been mentally prepared.

Looking at Yang Xiao and Fan Yao again, they were already dumbfounded, their hands trembled slightly, their chests kept rising and falling, and they were panting loudly, frightened by the scene in front of them and afraid to make a sound.

Neither of them expected that the power of the huo medicine and the firearm called shou thunder that the sect leader had so simply concocted would be so amazing.

The two of them looked at Ling Yun again, and their eyes changed from surprise to admiration.
