Dreaming about the world, embarking on the path of spiritual practice

Tibetan Scripture Pavilion

Yu Liang continues to come here to read books. He has not even read one-tenth of the books in this pavilion, so he will not waste time.

The more books he read, the more knowledge he gained, and the deeper Yu Liang had a deeper understanding of Yin and Yang.

Especially after coming into contact with the cold poison of Xuanming Divine Palm, he had some insights.

In heaven and earth, the things with the most yin and yang characteristics should be 'hot' and 'cold'.

‘Hot’ and ‘cold’ are adjectives used by people to feel changes in the external environment.

What is heat?

It is high temperature and high pressure, and a large amount of energy will be released during the process of cooling and reducing pressure.

What is cold?

It is low temperature and low pressure, and will absorb a large amount of energy during the process of increasing temperature and pressure.

Heat and cold are changes in energy.

How can high temperature and high pressure or low temperature and low pressure be formed?

Yu Liang had learned in junior high school physics class that he would take out a sealed needle tube with half of the air inside. By pressing and vacuuming, the pressure and temperature inside the needle tube would be changed.

By changing the pressure in the field, the alternation of yin and yang can be achieved.

How to change the pressure on the court?

The simplest way is through compression and extraction.

Yu Liang couldn't help but have an inspiration. If he controlled the aura first and compressed the air flow inside, he would be able to unleash even greater power.

When the air flow in the aura field is released, the aura field will also be able to form a suction force.

Release, absorb, one attack, one defense...

This is just an inspiration for him. If he wants to achieve this, there are still many things that need to be studied and learned slowly, so he is not in a hurry to study it now. The priority is to learn first.

The night is getting dark

Yu Liang left the Sutra Pavilion and returned to his residence.

Sitting cross-legged on the bed, he did not rest directly, but held today's trophy Yitian Sword in his hand and studied it carefully.

The battle with the two elders Xuan Ming made him understand that he must have a handy weapon.

If the sword hadn't been broken today, I wouldn't have let the two elders Xuan Ming escape.

This Yitian Sword is indeed a magical weapon, its hardness and sharpness far exceed any weapon he has ever seen.

The most important thing is that as long as it is swung quickly, the sword will make a sword sound.

This shows that whoever holds it is equivalent to possessing advanced swordsmanship.

Yu Liang held the hilt of the Yitian Sword in his hand and swung it out slowly at an extremely slow speed. During the process, he concentrated on observing the changes of the Yitian Sword.

The speed is too slow, nothing unusual.

Yu Liang gradually increased the speed of drawing his sword.

When reaching the normal sword-swinging speed of ordinary people, the airflow up and down the sword body flows rapidly, causing the sword body to tremble slightly. The faster the speed, the higher the frequency of its vibration.

Yu Liang stretched out a finger and flicked the sword lightly.

Buzz~buzz~buzz~

Just listen to the sound of the sword first going from weak to strong, and then getting weaker again.

The vibration frequency also goes from slow to fast, and then slows down again.

"interesting!"

Yu Liang continued to study for another hour and finally figured out the principle.

The reason why this happens is because the inside of Yitian Sword is hollow.

This is the same as sound wave reverberation. There is a cavity inside the sword body. A weak vibration wave is transmitted into it. The reverberation in the cavity will gradually become stronger, thus causing the frequency of the sword body to vibrate faster, and then slowly calm down. Come down.

Wonderful ideas and ingenious craftsmanship!

Go to bed and rest first.

Get up the next day and continue studying.

It took several days and various tests to collect all the parameters that could be collected from the Yitian Sword.

Then in the interior scene, an identical Heavenly Sword was manifested.

Immediately afterwards, Yu Liang came to the weapon refining room of the Wudang Sect.

This is a place dedicated to making weapons for sect disciples.

"Uncle Yu!"

The person in charge of the refining room saw Yu Liang arriving and hurried forward to greet him.

"May I have your name?"

"Reporting to Master, my disciple's name is Zhao Kai!"

This Zhao Kai had witnessed with his own eyes the scene of Yu Liangjian overwhelming the heroes, so he respected him very much.

"Zhao Kai, right? I want to build a weapon myself!"

Hearing Yu Liang's words, Zhao Kai smiled and replied: "What kind of weapon does Uncle Master want to make? Just tell me no. No matter what kind of weapon it is, our weapon refining room will do our best to build it. No need to bother Uncle Master." Do it yourself.”

Yu Liang shook his head slightly: "The weapons I made are a bit different, so I have to do it myself."

"It's just that I haven't made weapons before, so I have to ask you to teach me."

"Don't dare, don't dare~"

Hearing this, Zhang Kai panicked and said, "How am I qualified to teach Uncle Master!"

Yu Liang reached out and patted his shoulder, and said with a smile: "There is a saying that there is a priority in learning, and there is a specialization in skills. Why can't you teach me how to make weapons?"

Hearing these words, Zhang Kai couldn't help but be impressed by Yu Liang's character, and then respectfully replied: "Then the disciple will teach Uncle Master without overestimating his ability."

With that said, he led Yu Liang to a single building room.

First fill the charcoal into the stove, then light it, and pull the bellows on the side to let the charcoal in the stove burn violently.

Seeing that the fire was strong, he used iron tongs to pick up an iron ingot and put it into the fire to let it burn.

During this period, Zhang Kai told Yu Liang a lot about making weapons.

Until the iron block was red-hot, he clamped it to the anvil aside.

Zhang Kai took out a sledgehammer and handed it to Yu Liang, while he held a small hammer.

"Uncle Master, although blacksmithing is a heavy job, there is also meticulous care in the process."

"Later, I will use a small hammer to hit a spot on the iron block first, and then you will place the sledge hammer on the spot where I hit with the small hammer."

"When I tap once, it means I need to use a small force. If I tap twice, it means I need to use a medium force. If I tap three times, it means I need to use a strong force. Do you hear me clearly?"

Yu Liang held the sledgehammer in both hands and nodded to him.

"Okay, I'm going to start!"

Dang~dong~

Dangdang~dong~

Suddenly, with the cooperation of the big hammer and the small hammer, a dynamic rhythm was struck in the blacksmithing.

When the temperature of the iron block drops, Zhang Kai will put it into the fire and continue to heat it until it turns red, then take it out and continue hammering.

Slowly, the iron block gradually formed into the shape of an iron piece.

"Uncle Master, you can start the first quenching at this time."

"Weapon quenching is the most important step in making a weapon."

"Really good blacksmiths have a unique quenching method, some of which are even secrets."

While explaining, Zhang Kai put the iron piece into the water tank nearby.

The hot iron piece made a sizzling sound when it hit the cold water.

"Aside from water temperature, quenching is most important to timing!"

"If the quenching time is short, it will not be conducive to the subsequent tempering. If the quenching time is long, the iron will not be hard enough."

Seeing that the time was almost up, Zhang Kai took the iron piece out of the water and continued to put it in the stove for burning.

After the iron pieces burned red, the two continued to hammer.

Slowly, the prototype of the sword embryo gradually emerged, and Zhang Kai performed the second quenching.

Then the forging continued, during which Zhang Kai and Yu Liang talked a lot about forging.

Until the sword embryo is completely formed, the final third quenching is performed.

"Alright, Uncle Master, the construction of this sword is basically completed. After that, it's time to polish and sharpen it!"
