My dad is so rude

Chapter 29 Decibel Testing
After Chen Mu and Li Qing said goodbye, they went straight to the rented garage without going anywhere.

When we got there, we closed the garage door, and the pungent chemical smell hit our foreheads.

Chen Mu picked up the syringe, extracted a tube of sodium hydroxide, then raised his head, aiming at his left eye and injecting it.

"His-"

[Continuously attacked by venom... Vision +0.1, +0.1, +0.1]

[Continuously attacked by venom... Vision +0.1, +0.1, +0.1]

"..."

Then switch to the right eye.

[Continuously attacked by venom... Vision +0.1, +0.1, +0.1]

"..."

Chen Mu thought it was too troublesome to pour the drops into the eyes again and again.

He made a washbasin, poured two kilograms of sodium hydroxide into the basin, and then added water according to the proportion.

Stir well with a stick.

Chen Mu took a deep breath, and then slowly buried his face in it.

For a moment, he felt a hot feeling on his face.

[Continuous erosion by corrosive liquid, pain shift -72, -68, -66, -59...Skin strength +1, +1]

[Continuous erosion by corrosive liquid, damage transfer -33, -28, -26, -19...Skin strength +1, +1]

I don't know if his skin strength itself is relatively high, sodium hydroxide does little damage to him, and the attribute points are added very little.

But he didn't care, it wasn't for strengthening the skin in the first place.

He took a deep breath, then slowly opened his eyes.

In an instant, he felt a strong burning sensation in front of his eyes.

[Continuously invaded by the venom, pain shift -114, -107, -95, -83... Eyelid strength +6, conjunctiva strength +5, cornea strengthening +4, vision +0.1, +0.1, +0.1...]

[Continuously attacked by venom, damage transfer -101, -98, -76, -65... extraocular muscle strength +4, iris strengthening +5, retina strengthening +6, vision +0.1, +0.1, +0.1... 】

"..."

Hearing the constant reminders in his ears, Chen Mu was overwhelmed with joy!

"Hahaha... Awesome fucking, open the door for awesome-you're awesome!"

It's a pity that the time didn't last. After about 1 minute, the attribute points gradually increased very little.

At 3 minutes, the attribute points are completely over.

Sodium hydroxide no longer had any effect on him.

He raised his head, reached out and wiped the sodium hydroxide water on his face, turned his head and looked around the room,

Fine dust, spider's leg hair, finger prints on the glass...

Everything is invisible in his eyes.

It's like wearing glasses suddenly after being highly myopic, and everything becomes extremely bright.

"Fuck, if this goes on, it won't be long before my eyes can look up to the nine heavens and down to the ghost world?"

Chen Mu said something excitedly, but soon calmed down again.

He knew in his heart that he was dreaming.

As the body's resistance is getting higher and higher, or how long, ordinary toxic compounds will not have any effect on him.

Just like concentrated nitric acid, although he hasn't tested it yet, it certainly won't do him much harm.

It is estimated that in the future, finding toxic substances will become his top priority.

Then scooped 300ml of sodium hydroxide water with a measuring cup, and drank it "gurgling".

[Continuously attacked by venom...Gastric mucous membrane strengthening +1]

A glass of sodium hydroxide added a little bit of attribute points, which disappointed Chen Mu a bit.

But I continued to scoop up the sodium hydroxide in the measuring cup and drank it.

Mosquito legs are still meat no matter how small they are, so don't waste them.

While gulping down sodium hydroxide, Chen Mu was thinking about how to improve his sense of smell and hearing...

……

At 05:30 in the morning, Chen Mu was woken up by urinating.

Drank a lot of sodium hydroxide last night and the effect is minimal now.

Next he plans to try concentrated nitric acid...

After filling the water and returning to the room, the phone rang, and when I picked it up, it was Lin Xiangru calling.

"what's wrong?"

Lin Xiangru's excited voice came from the phone, "Dad, I have made a breakthrough... I am now a first-level warrior!"

A smile appeared on the corner of Chen Mu's mouth, "Fuck, awesome!"

"Well! From now on, I will be a real warrior, so happy!"

"Don't be proud, you have to keep working hard, you know?" Chen Mu encouraged, "By the way, we are going to start the test soon, right?"

"Yes, it will start in three days!"

"Okay, I see..."

After hanging up the phone, Chen Mu felt a sense of pride in being a father.

"You have to work hard, or a father who is surpassed by his son and daughter will be ashamed!"

Get up, brush your teeth and wash your face.

Chen Changqing also got up after hearing the movement, "Dad, is it so early today?"

"Just now your sister called, she has successfully broken through!"

"Really?" Chen Changqing had a joyful look on his face when he heard the words, "Yesterday morning she said it would take two or three days, so she planned to give us a surprise!"

"It's better to be conservative! How embarrassing it would be if the cowhide blows up?"

"That's right..." Chen Changqing nodded, "Dad, then I'll go downstairs to buy breakfast first!"

"Go! It's still the same, ten eggs, five steamed buns, plus a piece of milk."

"understood……"

After Chen Mu had breakfast, he went to the video store in the commercial street.

He wants to build a sound room, which will be filled with high-decibel speakers without disturbing the people, so as to increase the hearing property.

But before that, he wanted to see if the idea would work.

The boss brought Chen Mu to the audition room, where there are all kinds of mid-to-high-end speakers.

"That... I only have two requirements. The first decibel should be high, and the second, it should be cheap."

"If you don't consider the sound quality and just want high decibels, then you should buy a line array speaker. It's cheap and the decibels are high!"

"How many decibels can this reach?"

"Generally, it can reach 160 decibels, and better speakers can reach 180, or even 200 decibels! If it takes less than 1 minute, the ears will be deaf."

"Do you have it here? Let me try to hear the effect."

The boss hesitated for a moment, and Chen Mu immediately said: "Don't worry, boss, I will definitely buy it! Including the soundproof room, I will also pack it for you."

Once the boss heard this, there was nothing to hesitate.

Immediately dragged a set of line array speakers, connected to the power supply, and fetched a professional decibel measuring instrument, told Chen Mu how to operate the equipment and left the sound testing room.

Chen Mu closed the door and turned on the stereo.

Slowly increase the volume.

40 decibels - feels just right.

50 decibels - starting to get a little fidgety.

60 decibels - I feel a little fried.

70 decibels - Mental tension, blood flow speed up.

85 decibels—Chen Mu felt particularly uncomfortable, and had an urge to cover his ears.

At this moment, a familiar reminder sounded in my ear.

[Continuously attacked by strong sounds, damage transfer -30, -30, -30, -30... Tympanic membrane strength +1, hearing +1]

[Continuously attacked by strong sounds... the strength of the eardrum +1, the strength of the external auditory canal +1]

[Continued to be attacked by strong sounds...]

As the strength of the eardrum increased, Chen Mu immediately felt that the harsh music became softer.

He was overjoyed immediately, and it really worked.

Continue to increase the volume.

90 decibels - the music that just felt soft, immediately became particularly harsh.

But in the next second, the next second was to follow suit.

[Continuously attacked by strong sounds, damage transfer -50, -50, -50, -50... Tympanic membrane strength +2, external auditory canal strength +2, hearing +2]

[Continuously attacked by strong sounds... Hearing +1, +1, +1]

"..."

Chen Mu continued to increase the volume.

110 decibels.

This decibel is enough to pierce the eardrum of a normal person.

But Chen Mu only heard a sharp and ear-piercing sound like a blackboard scratching the blackboard.

In the next second, the sound disappeared.

[Injury force transfer -80, -80, -80, -80...Eardrum strength +3, external auditory canal strength +3, hearing +3...]

Chen Mu soared up, this is what he wanted.

He tuned it up—140 decibels!

[Damage transfer -140, -140, -140, -140... Tympanic membrane strength +6, hearing strength +6...]

Before he could be happy this time, several glasses on the diagonally opposite table and a row of glass frames on the wall were all shattered.

The screen of the decibel meter placed next to it flickered, and black smoke rose from it.

"not good!"

Chen Mu immediately turned off the audio.

"Clap-"

The glass on the wall still fell down, and the ground was a mess!
At this moment, he heard the soundproof room being knocked "bang bang bang" from the outside.

Chen Mu opened the door and found many spectators outside.

The boss squeezed in and said angrily: "You don't want to die, the sound is so loud? My soundproof room is only for sound testing, and the maximum sound insulation is only 100 decibels."

Chen Mu laughed and said, "Don't be angry, don't be angry... Don't worry, I will compensate you according to the price if it breaks."

"An accident happened, is it a matter of compensation?" The boss looked at the mess and roared angrily, "These big frames cost 300 yuan each, and the sound measuring equipment costs 580 yuan."

"Okay, I will compensate according to the price!" Chen Mu still said with a smile, "Also help me figure out how much the soundproof room and the stereo cost in total?"

Hearing this, the boss suddenly changed his face like a Sichuan opera. He was furious one second, and immediately asked, "How much square?"

Chen Mu thought for a while and said, "About 30 square meters."

The boss immediately forgot about the broken photo frame and the smoking sound detector, "Let's go, let's talk in detail..."
