Vol 2 Chapter 288: Voice change, cross dress, shape change

Four days later.
Laboratory, main laboratory.
Richard stood in front of the long experimental table and was preparing to go to the underground market again under the candlelight.
His eyes fell on his hands, and Richard looked at the ring he was wearing.
There are two rings on the left and right hands.
Among them, wearing the index finger on the left hand is the space iron ring. For now, it has three functions-absolute defense of space transfer, absolute cutting of space scissors, and absolute processing of space accuracy
The is worn by the old ring from the old Mullen, and the only role it can play at present is close to the fever of some books. Although it has little effect, it is the key to deciphering the secrets of the Baishi Tower and the Black Spirit King.
On the right hand, the No. 1 ring worn on the index finger is engraved with the magic lines of four curing spells-the brute force of the wind, the light spirit of the wind, the neurosensitivity of Pierce and the accelerated recovery. It plays a very strong role.
When Li Cha's head moved, the free energy elements flowed out of the source of the body's body, injected into the No. 1 ring to activate, and the four spells were released simultaneously, blessing the body.
Li Cha felt that the body was slightly heavy, and the armor formed by the condensation of air covered the surface of the body, and then the foot was light, and the air-condensed wind appeared on the foot, then the hairs stood up, the perception was amplified, and the cell metabolism was strengthened and restored. Speed ​​up.
"call--"
Richard Li breathed a sigh of relief, canceling the effects of the four spells and looking at the number two ring worn on the by his right hand.
Shortly after the second ring was made, it portrayed the magic lines of three curing spells-paralyzing lightning, frost freezing, and eroding toxins, which are not too weak.
Richard tried to activate the No. 2 ring, and he saw three inconspicuous lights flashing quickly above it. If these three rays of light fall on the enemy, the enemy will definitely feel better!
The role of ring two is completely different from that of ring one, and it can even be said to be opposite. The first ring is mainly used to increase its own ability, while the second ring is used to weaken the enemy's state. One increase and one decrease can establish a huge advantage in combat.
Now Richard has a rough plan for the subsequent production of the rest of the ring. He decided to share four to six magic pattern rings to strengthen different abilities, assist him in the apprenticeship of the sorcerer, and ensure that he has a positive confrontation with the genuine wizard. Ability.
After reviewing the ring, Richard flipped his hand and took out a variety of medicaments from the space iron ring, such as "Trial Acuity Pharmacy", "Spartan Heroic Pharmacy", "Spartan Warrior Pharmacy" and so on.
Compared to the ring, these potions can't exert their effects permanently, but they can significantly enhance a certain aspect of the body within a certain period of time, thus breaking the deadlock in battle.
In Richard's view, these medicines are generally unavailable, especially this time to go to the underground market. However, the preparation is absolutely over with no mistakes.
Putting away the potion, Li Cha flipped his hand, and a blood-red eyeball-shaped bead came in his hand. This is a bead of destruction from Old Mullen. According to Old Mullen's description, it is powerful enough to kill the real wizard, which is his current card. Of course, just like the pharmacy, he didn't think he would use it to go to the big market this time, at best he was prepared.
In fact, in his view, this time going to the big market, if there is no accident, only need to show a part of the strength, it will smoothly enter the interior of the Taboo Bookstore, and ensure that no identity is revealed.
Of course, before that, you need to...pretend.
Richard put away the Destruction Beads and began to pretend to be a person with a new appearance and new identity.
A spell was pronounced in Li Cha’s mouth to allow the trick of
water droplets to condense
to work. A part of the special gas in the air was separated and slowly gathered together. After most of the sound, it became a transparent bubble and slowly posted On the body surface.
It seems that there is no difference from the normal one, but Li Cha's heart moved, and the transparent bubbles slowly opened a gap, and part of the gas entered the mouth. Richard tried to make a sound. The sound was very different from the original one, and it seemed sharp.
This is so because the gas inhaled is helium.
Generally speaking, the human body can make sound because the air in the lungs passes through the vocal cords, causing the vocal cords to vibrate and generate sound waves. The sound wave changes through the vocal tract, and comes out of the lips into sound.
The speed of sound in different media is different. Under normal circumstances, the sound channel in the mouth and nose of the human body is filled with 1.293kg/m3 of air, and the speed of sound propagation in it is 340m/s.
After inhaling the inert gas helium in the sound channel, because the helium is 0.1786kg/cubic meter, which is much lighter than air, the speed of sound propagation will increase by nearly three times, and the sound will become sharp.
And if the channel is filled with some other gas heavier than air to make the sound slower, then it will sound low. UU reading books www.uukanshu.com
Using this method to change the voice and disguise your identity, there is a big advantage is convenience. Because the nature of the gas and the speed of sound propagation are fixed, as long as the gas is inhaled reasonably, one can ensure that one does not need to make any changes to change the sound into another. It is much simpler than deliberately out-of-tune and deliberately disguised as another sound, and it will not damage the fragile vocal cords.
Of course, it should be noted that this method cannot be used continuously. In other words, the inert gas cannot be continuously drawn in to make a sound. Because the inert gas does not contain oxygen, attempting to breathe in the inert gas will cause suffocation.
The solution is also simple. That is to take a breath of inert gas and say something, then pause for a while, inhale normal air to supplement the body's metabolic oxygen consumption, and then continue to inhale inert gas to make a sound.
When using this method, the pause can be disguised as silence or thought, and hardly doubted.
Thinking in this way, Richard uses "condensed water droplets" to constantly adjust the type of gas, and the testers' voices are different. In the end, he chose a more desirable gas, which made his voice dumb, and it sounded like he was quite old.
After disguising his voice, Richard began to disguise his face, using various cosmetics to modify the details of his face, making his eyebrows thicker, his eyes bigger, and his skin darker...
After finishing the makeup, Li Cha looked at his glasses and nodded with satisfaction, and then began to wear new decorations: a thick black robe covering most of his face, half-finger black leather gloves, high-heeled boots...
In the end, Richard looked at the mirror and saw that he had completely changed his appearance and could not find any features of the original.
"Very good." Li Cha said in a dumb voice, nodded, and walked out of the laboratory to the underground market.
