As soon as it was dawn, Cheng Chuliang sat in the courtyard, staring at the gramophone in front of him, and he carefully observed the structure of this thing, which was nothing more than an iron rod, a horn made of wood, and a tin foil wrapped in an iron rod.

The combination of these ordinary things, and the ability to speak, made him feel incomprehensible. But it is precisely because of this that his belief in apprenticeship has also become stronger.

When it was time for breakfast, Cheng Qishi saw that Cheng Chuliang had not yet arrived, and he was puzzled, so he asked the maid to call Cheng Chuliang.

The little maid was obviously in a good mood today, and the fourteen-year-old little maid was humming a pleasant song to the courtyard where Cheng Chuliang was, and Cheng Chuliang was intently shaking the handle of the gramophone.

The little maid straightened her clothes and was about to speak, but suddenly she heard something strange on the stone table speak.

"Master, I said, I really said, but what did I say?"

The maid was stunned for a moment when she heard something strange talking, and she was stunned for a moment, and the scream that pierced the dawn of the morning almost spread throughout the entire Cheng Mansion.

"Youkai!"

Cheng Chuliang was startled by the sudden scream, and when he turned around, he saw the back of a little maid running away.

And the screams of the little maid completely broke the tranquility of the Cheng Mansion, and the servants and maids were a little dazed for a while.

In the Tang Dynasty, the subordinates and maids who have not received much education are quite superstitious about the theory of ghosts and gods, and most of them even say that they have witnessed ghosts in their hometowns, which scared many maids to lose sleep at night.

And this monster made many timid maids panic.

When the next person found the little maid hiding in the corner and crying, he asked her what had happened? The little maid just cried and did not answer.

Soon Cheng Fei's hostess, Cheng Yushi, was also alarmed, because Cheng Yanjin had to go to the morning court every morning, so Cheng Fei's family was in charge of Cheng Mansion every morning.

Cheng Qishi quickly inquired about the cause of the riot and asked the little maid to be passed on.

When the little maid saw Cheng Yushi, she knelt in front of her crying,

"Please forgive me."

Cheng Qi's resignation,

"I remember asking you to call Erlang-kun for dinner."

The little maid nodded, sobbing,

Cheng Yushi frowned unhappily and said patiently,

"Tell me, what's going on."

The little maid saw that the hostess was displeased, and was obviously panicked,

"It's not that the maid disobeyed Madame's orders, it's just that the maid saw Erlangjun, but she saw something strange and spoke."

Cheng Qishi was a little incomprehensible,

"Weird stuff?"

The little maid suddenly seemed to have found the backbone of the heart, and cried very much,

"Madam, it's just that thing is too scary, it's obviously a dead thing, but it speaks a human tongue, it must be a monster, madam."

Cheng Qishi just wanted to scold the little maid, where did the monster come from in this world.

But then there was a riot in the Cheng Mansion again, and this time the riot was obviously much bigger than that of the little maid.

The main reason is that a subordinate inquired that the little maid went to call Erlangjun to have dinner and met the monster, which attracted the curiosity of many subordinates and maids, and they all wanted to witness the true face of the monster, so they organized a group to go to Cheng Chuliang's courtyard.

This time it completely made Cheng Mansion like boiling water, and all of a sudden the maids ran all over the courtyard, shouting, trying to find a place to hide.

Cheng Chuliang despised a group of uninformed servants, this is my master's immortal weapon, do you understand the immortal weapon? What is a yokai called? Isn't this an insult to my master?

At this time, Cheng Qishi came to Cheng Chuliang's small courtyard with a black face,

"Liang'er, what are you messing around again?"

Cheng Chuliang saw that it was Cheng Yu's coming, although she was Cheng Bitingjin's wife, that is, her stepmother. But Cheng Qi's family treats Cheng Yanjin's ex-wife and brother as his own, and Cheng Chuliang is also quite respectful to her.

"Mother, the child is studying the homework assigned by the master."

"Master?"

Cheng Qishi was a little puzzled for a while, this era will not use the word master to describe the master.

"When did you have an extra master?"

Cheng Chuliang explained the matter as it was, and Cheng Qishi understood,

"But the boiling immortal disciple who has been rumored by the outside world recently."

"Exactly."

Cheng Xuan's clan came out to Qinghe Clan, he has received a good education since he was a child, and he doesn't believe in the theory of ghosts and gods, but he has also heard of what the disciples of the immortal family said. In addition, Cheng Chuliang bought back an astronomical telescope, which is the legendary immortal weapon, and she is also the one who has seen the true face of the moon with her own eyes.

Although he was skeptical of the so-called immortal duel immortal art, there was no doubt that the immortal disciples who could make clairvoyance were worthy of their reputation, and they were not comparable to ordinary warlocks who had lost their reputation.

Cheng Yushi looked at the gramophone in front of him and asked,

"This is the gramophone that captures human voices?"

When the subordinates and maids behind him heard this, their faces turned pale for a while, and it was terrible to be able to catch people's voices.

Cheng Chuliang nodded, took out a thin piece of tin foil again, and wrapped it on the iron rod.

"As long as you talk to this horn thing, and turn this handle at the same time, the sound will be caught, this is a topic given by the master to the child, that is, let the child understand this fairy weapon called the gramophone, can the mother try it?"

Cheng Qishi glanced at the gramophone, and felt a little mad at this kind of unfounded thing in her heart, she glanced at the person next to her,

"You go and try."

When the man heard this, his face turned pale with fright, and he knelt on the ground with a pop, and cried out with a handful of tears and snot,

"Madam, there is a fifty-year-old mother in a certain family, and there are children who are running old, and a certain ......."

Cheng Qishi waved his hand impatiently,

Cheng Chuliang's face is a little unpleasant, why did my master's immortal weapon become a monster in your eyes?

Then a maid came in a hurry.

"Madam, Princess Qinghe and Princess Gaoyang are here."

Princess Qinghe is the sugar cane girl of His Majesty Li Er, and she was engaged to Cheng Chuliang as early as three years ago.

The Tang Dynasty was relatively open, and it was also this opportunity, Princess Qinghe occasionally came to play with Cheng Qingqing, the eldest daughter of the Cheng family.

Cheng Yushi nodded, and then took his subordinates and maids to find Princess Qinghe.

This little episode did not have much impact on Cheng Chuliang, but it seemed relaxed, and he continued to study the gramophone.

But Cheng Chuliang has not studied acoustics, nor does he have a physical foundation, so it is impossible for him to understand his principles at all.

However, the thinking of people in this era was not completely restrained as it was after the Song Dynasty, and Cheng Chuliang's thinking was active.

He found that if he wanted to leave the sound, he had to make the rounded end of the wire that connected the horn turn with a gentle rub against the tin foil.

And without tin foil, there will be sound, but there are some very heavy noises, which are not heard at all.

In other words, even without tin foil, you can grab the sound, but you can't hear it at all because the noise is too loud.

These discoveries allowed Cheng to find a direction.
