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

…

Leave Xiaoyuzhuang and return to the county seat

Yu Liang lived a stable life again.

During this period, he has been delving into the knowledge of ‘sound waves’.

The most difficult thing in the world is to go from zero to one.

The Snake King's Magic Power brought Yu Liang 'thermal sensing ability', allowing him to sense the existence of heat energy.

He naturally wants to tap and develop this ability to the greatest extent.

Sound wave is a kind of mechanical energy. When its frequency reaches a certain value, it will generate heat energy.

In the book network, the knowledge about the heat energy generated by sound waves mainly involves the medical field, industrial field and agricultural field.

Yu Liang actually wanted to read about the knowledge related to the field of weapons, but unfortunately it was not available on the book network. It may be that he did not have enough authority and was not qualified to read it.

In the medical field, the thermal effect of ultrasound is widely used in treating tumors, eliminating pain, and promoting wound healing.

The high-frequency vibration of ultrasound can produce a thermal effect, destroying tumor cells, thereby achieving therapeutic effects.

The thermal effect of ultrasound can also promote blood circulation, accelerate wound healing, relieve pain, etc.

In the industrial field, the thermal effect of ultrasonic waves is widely used in cleaning, welding, cutting, etc.

In the agricultural field, the heat energy generated by the sound wave generator can also promote seed germination and growth.

The vibration of sound waves can accelerate plant growth and improve yield and quality.

The learning of knowledge all starts with definition and understanding.

Sound waves are mechanical energy, and high-frequency ultrasonic waves can produce thermal energy.

Then there is the principle of knowing, explaining why ultrasonic waves generate heat energy.

When sound waves travel through the air, they cause the air molecules to vibrate, and this vibration causes friction between the air molecules, which creates heat energy.

Then, there are formulas and data!

Formulas and data are the most important because they allow people to understand how to act from 'knowing' to 'doing'.

[The formula for the atomic bomb: E=mc.

The formula is the theory of the atomic bomb.

Only by knowing the data of formula calculation can we build an atomic bomb. 】

The formula for sound waves: wavelength times frequency equals wave speed.

To master the power of sound waves, Yu Liang had to learn and master a large amount of data.

These can be seen in papers published in some scientific journals.

First of all, Yu Liang read experimental papers on ultrasound in the medical field.

In the experimental results and data analysis in the paper, the specific data of the experiment are listed in detail, including the number of samples in the experiment, experimental conditions, measurement values, statistical results, etc.

According to these data, the experimental process and results can be repeated as long as they are copied.

There was so much data in one experiment that it took Yu Liang several days to read it all.

Yu Liang watched very carefully and seriously. This was important knowledge for him to learn how to use ultrasound to treat tumors, eliminate pain, and promote wound healing.

Ten days passed quickly.

Yu Liang once again traveled to the world of Xiaoao.

After practicing for more than half a year, the giant python shed its skin again.

Yu Liang thus obtained the fifth level of the Snake King Magic Skill.

The fifth level of Snake King Magic did not bring him new abilities, it just made his aura stronger.

Just when Yu Liang was immersed in practice,

Three letters from outside were delivered to him one after another.

These three letters all talk about the same thing. Zhengdao is besieging Heimuya. Among them are not only the Five Mountains Sword Sect led by the Zuo Lengchan Sect of the Songshan Sect, but also the Kunlun Sect, the Qingcheng Sect and the Beggar Clan.

"Wudang and Shaolin didn't take action, how dare these guys dare to go to Heimu Cliff?"

Yu Liang originally didn't want to go to support, but one of the three letters was from Qu Yang, and the other was from the master.

"Oh, Master, you finally healed your injury, and you've already retired, why are you still joining in the fun!"

After receiving the letter, Yu Liang immediately set off for Heimu Cliff.

It’s been a long and dusty journey.

When Yu Liang arrived at Heimuya, the Righteous Alliance had just entered the borders of Hebei.

This was before the Sun and Moon God Sect did not stop them.

It took them most of their time just to gather around the world.

According to Dongfang Bubai's instructions, she sent the Righteous Alliance to Blackwood Cliff, where she wanted to defeat the Righteous Martial Arts in one fell swoop.

When they got to Heimu Cliff, everyone saluted politely after seeing him, not only because of his high status, but also because of the strength he showed in the battle in Fuzhou, which they had to admire.

Seeing Master Ma Wu, he was getting together with Qu Yang at the moment.

"Master!" "Brother Qu!"

"Now that my disciple is here, we will have a better chance of winning this battle."

Yu Liang leaned into the master's ear and whispered: "Master, you have already lived in seclusion, why are you here?"

"Haha, my master has recovered from his injuries and his martial arts has improved again. I want to stretch my muscles and bones!"

"By the way, apprentice, I have good news to tell you. I have married you a new wife. She just got pregnant recently, hahaha~"

"What?"

When Yu Liang heard the news, he was shocked.

Master, he is already so old, he actually married another wife and got pregnant by someone. He is really getting stronger with age!

No wonder he looked so energetic and even came to the black wood cliff to join in the fun.

"Envoy Yu, the leader has summoned you!"

A cultist came to Yu Liang's side and said respectfully.

He looked at his master and Qu Yang, and then said to the believer: "Lead the way ahead."

"Envoy Yu, please come this way!"

Following him, Yu Liang came to a garden behind the divine palace.

I saw Dongfang Bubai in the pavilion in the center of the garden.

Dressed in red, with long flowing hair and a graceful figure, she holds an embroidery needle in her hand and slowly embroiders flowers on a screen in front of her.

"Leader!"

Yu Liang bowed his hands and bowed.

Dongfang Bubai ignored him at first, then turned around suddenly after a moment, and the embroidery needle in his hand popped out.

"Ahem~"

Yu Liang coughed lightly, and the embroidery needle that was not close was affected by the invisible sound waves and was shot in another direction.

Dongfang Bubai pinched the red silk thread connected to the embroidery needle with his hand, shook it slightly, and the embroidery needle shot towards him again.

Yu Liang raised his hand and stretched out two hands to easily clamp the embroidery needle.

Seeing this, Dongfang Bubai stood up with a smile, twisted his body in a pretentious manner, and whispered softly: "Messenger Yu is really hiding something~"

"I'm afraid there are not many people in this world who are your opponents!"

"The leader is joking!"

Yu Liang flicked the embroidery needle in his hand and shot it back to the screen in front of Dongfang Bubai.

Dongfang Bubai also took advantage of the situation and sat down, picked up an embroidery needle, and started sewing stitch by stitch.

"The Righteous Alliance will arrive at the foot of Blackwood Cliff in four days. How about we leave them to Messenger Yu?"

Hearing this, Yu Liang smiled and replied: "I think it is most appropriate for the leader to take action himself!"

"This is a good opportunity for the leader to show off his power and increase his prestige. I won't overstep it!"

"Okay then, go down!"

"I'll resign!"

Looking at Yu Liang's leaving figure, Dongfang Bubai showed a strange smile on his face.
