Four days later.
Laboratory, main laboratory.
Richard stood in front of the long experimental table, preparing to go to the underground market again under the light of candlelight.
His eyes fell on his hands, and Richard examined the ring he was wearing.
There are two rings on each of the left and right hands.
Among them, the one on the left hand, worn on the index finger, is a space iron ring. As of now, it has three functions - absolute defense of space transfer, absolute cutting of space scissors, and absolute processing of space precision.
The ring worn on the middle finger is a simple ring obtained from old Mullen. Currently, the only function it can play is to generate fever in certain books. Although its role is small, it is the key to deciphering the secrets of the White Stone Tower and the Black Spirit King.
On the right hand, worn on the index finger is Ring No. 1, which is engraved with four magic patterns that solidify spells - Brute Force of Wind, Lightness of Wind, Pierce's Nerve Sensitivity and Accelerated Recovery, which play a very powerful role.
As soon as Richard thought, the free energy elements surged out from the magic source in his body, injected into the No. 1 ring for activation, and the four spells were released at the same time, blessing the body.
Richard felt his body become slightly heavier at first, and the armor made of condensed air covered the surface of his body. Then he stepped lightly, and the wind shoes condensed by air appeared on his feet. Then his hairs stood up, his senses were amplified, and his cell metabolism was strengthened and restored. Speed up.
"call-"
Richard took a long breath, canceled the effects of the four spells, and looked at the No. 2 ring on the middle finger of his right hand.
Not long after the second ring was made, it was engraved with three magic patterns that solidify spells - paralyzing lightning, freezing frost, and corrosive poison. They are not weak either.
Richard tried to activate Ring No. 2 and saw three inconspicuous lights flashing quickly on it. If these three rays of light fall on the enemy, they will definitely feel better!
The function of the No. 2 ring is completely different from the function of the No. 1 ring. It can even be said to be opposite. The first ring is mainly used to increase one's own abilities, while the second ring is used to weaken the enemy's status. One increase and one decrease can establish a huge advantage in battle.
Now Richard has a rough plan for the subsequent production of the rest of the rings. He has decided to use a total of four to six magic pattern rings to strengthen his abilities in different aspects, assist him in fighting at the wizard apprentice level, and ensure that he has the ability to fight against real wizards head-on. Ability.
After examining the ring, Richard flipped his hand and took out a variety of potions from the space iron ring, such as "Trial Sensitivity Potion", "Spartan Heroic Potion", "Spartan Warrior Potion", etc.
Compared with rings, these potions cannot have permanent effects, but they can significantly enhance a certain aspect of the body's abilities within a certain period of time, thereby breaking the deadlock in battle.
In Richard's opinion, these medicines are generally not used, especially this time when going to the underground market. However, there is nothing wrong with being prepared.
Putting away the potion, Richard turned his hand and found another blood-red eyeball-sized bead in his hand. This is the Destruction Bead obtained from Old Malen. According to Old Malen's description, it is powerful enough to kill a real wizard in an instant, and it can be regarded as one of his current trump cards. Of course, just like the medicine, he didn't think he would use it when he went to the big market this time. At most, he was just prepared.
In fact, in his opinion, if there are no accidents when going to the big market this time, he only needs to show part of his strength and he will smoothly enter the inside of the Forbidden Bookstore without exposing his identity.
Of course, before that, you need to...disguise.
Richard put away the Destruction Bead and began to disguise himself as a person with a new appearance and a new identity.
Richard chanted a spell in his mouth and let the trick of "water droplet condensation" work. Part of the special gas in the air was separated and slowly gathered together. After a while, it turned into a transparent bubble and slowly stuck to it. on the body surface.
It looked no different from normal, but with a thought, Richard made the transparent bubble slowly open a gap, and part of the gas entered the mouth. Richard tried to speak out, but his voice was very different from the original one and seemed sharp.
This is so because the gas being inhaled is helium.
Generally speaking, the human body can make sounds because the air in the lungs passes through the vocal cords, causing the vocal cords to vibrate and produce sound waves. Sound waves change through the vocal tract and emerge from the lips as sounds.
The speed of sound propagation in different media is different. Under normal circumstances, the vocal tract in the human mouth and nose is filled with air weighing 1.293kg/cubic meter, and the propagation speed of sound in it is 340m/s.
When the inert gas helium is inhaled into the vocal tract, because helium is 0.1786kg/cubic meter, which is much lighter than air, the propagation speed of sound will increase nearly three times, and the sound will sound sharp.
And if some other gas heavier than air is used to fill the vocal tract to slow down the sound propagation, it will sound muffled.
One of the great advantages of using this method to change your voice and disguise your identity is convenience. Because the properties of gas and the speed of sound propagation are fixed, as long as the gas is inhaled reasonably, a person can guarantee that the sound will become another one without making any changes. It is much simpler than deliberately going out of tune and deliberately pretending to be another voice, and it will not cause damage to the fragile vocal cords.
Of course, it should be noted that this method cannot be used continuously. In other words, you cannot continuously inhale inert gas to produce sounds. Because inert gases do not contain oxygen, trying to inhale inert gases and make sounds will cause suffocation.
The solution is also simple, that is, take a breath of inert gas and speak for a while, then pause for a while, inhale normal air to replenish the oxygen consumption of the body's metabolism, and then continue to inhale the inert gas to make sounds after replenishing.
When using this method, the pause can be disguised as silence or thought, and there will be almost no suspicion.
With this in mind, Richard used "condensed water droplets" to continuously adjust the type of gas and test the differences in the voices of the people. Finally, he chose a more satisfactory gas, which made his voice hoarse and made him sound like he was not young.
After disguising his voice, Richard began to disguise his face, using various cosmetics to modify the details on his face, making his eyebrows thicker, his eyes bigger, and his skin tone darker...
After finishing his makeup, Richard glanced at the mirror and nodded with satisfaction, and then began to wear new decorations: a thick black robe that covered most of his face, half-fingered black leather gloves, high-heeled boots...
In the end, when Richard looked in the mirror, he saw that he had completely changed and could not find any of his original characteristics.
"Very good." Richard said in a hoarse voice, nodded slightly, and walked out of the laboratory and towards the underground market.
