The master and Taoist priest returned to his wing room and found a "magic weapon" that he loved as much as his life from a corner at the bottom of the box. Wang Chen took it and saw that it was a bronze bell the size of a palm. The outer wall of the bronze bell was engraved with dragons and tigers, which can suppress evil spirits. Wang Chen bumped the bronze bell and began to press his hand.

It seems that it is not only mixed with bronze.

Looking at the inner wall of the bell, there are long and short mysterious lines with silver wire as the core and lead wire wrapped. These lines are connected and outlined to form a very complex integrated pattern.

"Is this a magic weapon?" Wang Chen was a little unbelievable.

Teacher Gong explained: "Master Shao, this corpse driving bell is the only magic weapon in the disciples' hands. The corpse driving bell is originally a kind of magic weapon used by the disciples who go down to Maoshan to drive away the corpses. With the magic formula, even the disciples with weak magic power can drive away the corpses. They travel more than 100 miles day and night to provide corpse materials for the corpse smelting in Xiamao mountain. It is a magic weapon that everyone has when I go down to Maoshan."

"This magic weapon is very popular, but it's not unique to my xiamaoshan family."

"Although I have lost my sense, with the power of this magic instrument itself, I can still make my disciples drive away the body a little!" Master Gong Laodao opened the lid of a coffin. He lifted up a walking corpse processed with secret medicine and ordered the little apprentice to bring some very tough bamboo poles. He saw master Gong bend the bamboo pole into a bow and tie it down the spine of the corpse to form an arched support to support the corpse.

After he tied up, there was a bamboo pole behind the walking corpse. The feet of the walking corpse formed a triangular stable support. Then he straightened the hands of the corpse and tied them with a bamboo pole. When everything was ready, a spring support was formed behind the walking corpse.

Division commander Gong twisted the corpse bell and began to practice. He saw his eyes closed and his right hand holding the bell shaking constantly, making the bell emit all kinds of large and small, long and short noisy bells. These sounds were very messy and rarely the same. When the bell made a short and urgent sound, the corpse suddenly twitched all over his body. Driven by his limbs, the bamboo pole bent downward, When it was restored due to elasticity, it bounced the body upward, which looked like the body jumped.

This movement surprised Wang Chen! He looked at the division commander Gong as if he had found something key. He kept trying to adjust the frequency with the bell that had just made the walking corpse react. At this time, Wang Chen saw it. It seems that a certain frequency of the corpse pile corpse bell has a special response to the sound of the timbre. Whenever he heard the bell close to that sound, his limbs twitch.

At this time, the corpse had been forced to jump all over the yard by the constantly adjusted bell of the division commander palace.

Wang Chen has seen the doorway. It turns out that the teacher Gong is constantly adjusting the bell tone to find the frequency that works on the walking corpse, and then around this frequency, he tries to adjust the frequency and timbre, and test the reaction of the walking corpse. Then, he can shake the bell to control the forward direction, step frequency and size of the walking corpse, driving them to walk freely.

"This is the corpse driving?" Wang Chen said in surprise: "the different sounds of the bell control different walking corpses... That kind of bell sound can only control one corpse. The corpse driving craftsman can transport dozens or hundreds of walking corpses at a time. Is it also controlled one by one with the bell?"

The teacher Gong stopped the ring tone and said in shame: "it didn't have to be like this before. Just practice a door control corpse formula, you can unify the sound of controlling the walking corpses, and only one sound can control all the walking corpses. Now... It's only because this door found that it was lost that the old Taoist priest had to do so."

"Many of your Dharma formulas have been lost... No, it should be said that almost all the things about mana have been lost except a few basic ones." Wang Chen said with emotion: "and it doesn't look like driving away the corpse. Instead, it uses the elasticity of the bamboo pole to assume a subtle mechanical structure, which turns the twitching action of the corpse into forward elasticity."

"The way to make the body twitch... Ring tone stimulation." Wang Chen frowned: "I've heard of frog jumping reaction. After cutting off the lower body of the frog, connect the wire connecting the current to the frog's nerve. After the power is connected, the dead frog's legs will bounce - this is a small experiment to explain nerve reflex and bioelectricity."

"You drive the corpse - why is it so like bioelectricity to stimulate the corpse!"

Wang Chen picked up the corpse bell and looked at the suspicious lines on the inner wall of the bell. He was even more suspicious. "Although there are some differences in the feeling of this law, the essential law is the set of integrated circuits - this is an integrated circuit that adopts different standards and even slightly distinguishes its development direction. If it is analyzed from a scientific point of view..."

"The corpse driving bell uses sound waves... No, it should be electromagnetic waves that stimulate the residual bioelectricity in the corpse to promote the stress response of the corpse. Through the external mechanical structure, the kinetic energy of the convulsion of the corpse is transformed into elastic potential energy, and then into bouncing kinetic energy... This is the secret of the corpse driving bell to drive away the corpse."

"The electromagnetic wave of the corpse bell is generated by the change of current and magnetic field caused by vibration. The timbre and audio frequency are actually a sign of electromagnetic wave frequency. The information of electromagnetic wave change is translated through audible sound waves."

"Is this' magic weapon 'made by the practitioners of the Ming Dynasty, like the life support warehouse of my ancient magic weapon, a scientific and technological product? Or is the essence of the magic weapon of the corpse bell, a vibration controlled electromagnetic wave remote bioelectric stimulation device?" Wang Chen is convinced of his reasonable and scientific inference, but he still has one question.

"Then, where did Jiugong, a Ming Dynasty man, learn the technology of stimulating corpse bioelectricity and electromagnetic wave emission?"

Wang Chen couldn't help looking at his life support warehouse.

"This magic weapon..." Wang Chen said with emotion: "maybe I have some ideas!"

Martial master Gong was overjoyed when he heard this. He demonstrated the secret method of Xiamao mountain to Wang Chen again and again. However, the master of the iron coffin, the fundamental treasure of Xiamao mountain, had no clue about the Taoism that Jiugong's ancestor understood from the strange coffin. Even Wang Chen was a little nervous. He knew that the only reason why Shichang Gong and his disciples regarded him as their ancestor was to revitalize Xiamao mountain. If he had been incompetent, Teacher Gong will turn against him sooner or later.

Although Wang Chen, armed with a gun, was not afraid of this half hearted Taoist old man, he finally accepted it. Wang Chen still felt some heartache when he came to the world and met the first "force" rebellion.

Wang Chen, who learned a little, was very relaxed, but to really transform this magic weapon, he had to use the life support warehouse to unlock some secrets of the mysterious high-tech products that Wang Chen had been close to when he came to the world.
