Calcium oxide, chemical formula CaO, is made from calcined limestone, so it is called calcined lime, also called quicklime, and appears as a white powder.
Calcium oxide is an alkaline oxide that is sensitive to moisture and easily absorbs carbon dioxide and moisture from the air. After reacting with water, the calcium hydroxide (Ca(OH)2) solution generated is a medium-strong base and can neutralize acidic substances.
…
"Bang bang bang..."
Bags of calcium oxide piled up in Richard's yard as high as a hill.
After a long time, the pile was finished.
"How about it, my dearest friend, Mr. Richard, are you satisfied with the goods this time? Let me tell you, the goods I helped you get this time are definitely the highest quality goods, without any impurities in them. Moreover, the price was not quoted at all. I can swear to this - in the name of my ancestors!" Alex came to Richard's side and said sincerely, but no matter how sincere his expression was, there was always a hint of There is a kind of treachery that cannot be concealed.
Richard didn't believe what Alex said at all: It's weird if it's the best product! It’s strange that they didn’t quote a high price at all!
But I don’t want to worry about these, after all, as long as it can be used satisfactorily. The next moment, his eyes flashed, he didn't say anything more, he paid the balance as agreed, and sent Alex and the coolie away with a wave of his hand.
After Alex and the coolie left, Richard approached the piled calcium oxide bags, loaded the calcium oxide into the space iron ring, and then walked into the modified magic laboratory below the main laboratory.
…
In a blink of an eye, night falls.
Richard's figure appeared in the cemetery outside Baishi City. Because he had come so many times, he almost walked to the grave of Alex's ancestor with his eyes closed.
Bend down, reach out, and press to the ground.
The "Earth and Stone Control" spell was activated and the ground cracked.
Glancing at the chlorine gas filling the passage, Richard took out the familiar iron bucket from the space iron ring and opened the lid.
This time, the iron can was no longer filled with chlorine gas, because the tomb had obviously been filled with enough chlorine gas. This time, it was filled with a saturated calcium hydroxide solution to neutralize the chlorine gas.
After all, turning the tomb into a devil's cave full of chlorine might eliminate all dangerous beings, but it would also make it impossible for him to enter. Even if you force entry with an oxygen bottle attached, you have to consider whether the oxygen bottle will be corroded by chlorine, and how far your line of sight can penetrate in the high concentration of chlorine.
Therefore, in order to ensure that he can successfully explore for the third time, he must find a way to neutralize the chlorine gas.
This is the same as when they used the tunnel to bury and kill Suomen in the forest of the Emerald Kingdom - it took a lot of effort to blow up the tunnel at first, and then it took a lot of effort to dig out the other party's body.
Thinking of this, Richard began to cast the "water droplet condensation" spell in reverse, causing the calcium hydroxide in the iron can to atomize into tiny water droplets, forming a vast white mist, which poured into the depths of the tomb along the downward passage, quickly Reacts with yellow-green chlorine gas.
Visible to the naked eye, the mist is like a beast with a wide mouth. Once it comes into contact with chlorine, it immediately swallows it up.
The calcium hydroxide mist is as powerful as breaking bamboo, advancing layer by layer.
Soon, one iron can of calcium hydroxide solution was used up, and Richard began to take out the second can to atomize and neutralize it.
Then the third can, the fourth can, the fifth can...
Not long after, all the calcium hydroxide solution in the iron cans in the two space iron rings was consumed, and Richard discovered that a problem that had troubled him before reappeared.
That is, in order not to attract attention, he could only quietly bring calcium hydroxide solution to the tomb at night. However, due to the limited reserves of the iron rings in the two spaces, the amount of calcium hydroxide solution he transported was severely limited. It can continuously transport and act as a transport worker.
"call-"
Richard let out a sigh of relief. He had no choice but to accept this problem. It just took more time.
Without much hesitation, Richard carefully repaired the cracked passage in the ground, and quickly returned to the laboratory.
After that, for several days and nights, Richard kept running between the laboratory and the cemetery.
…
A few days later, on a dark night with few stars, Richard estimated that the chlorine content in the tomb had dropped to an acceptable range. After thinking about it, he decided to start a third exploration.
Cemetery, in front of the graves of Alex's ancestors.
Richard atomized the calcium hydroxide solution in the iron ring cans that filled the space, controlled the influx into the tomb, and collected the empty iron pipes.
Taking a deep breath, he took out a set of weird clothes from the iron ring in another space. This is a one-piece leather coat painted with special paint, and comes with leather socks and a leather hat. After putting it on, put on the beak mask, put on the modified oxygen bottle on his back, and connected it with a leather tube. Richard was already under good air-tight protection.
After calming down, moving his limbs, and adapting to his new, somewhat bloated state, Richard walked towards the tomb.
Admittedly, Richard felt that the chlorine in the cemetery had been neutralized and diluted so that there was no danger, but out of a cautious attitude, he decided to wear protective clothing and go in to check the situation.
Just like that, Richard walked into the passage and disappeared on the ground.
The third exploration - an exploration that Richard was confident and thought could be pushed forward, began.
…
The night is dark.
At the same time that Richard entered the tomb, two black shadows appeared silently in the center of the White Stone City, the White Stone Tower Complex.
The two figures are a man and a woman, or in other words, they appear to be a man and a woman—Solmen and Mukeni.
The two of them scanned the surroundings vigilantly, and after making sure that no one noticed, they looked at each other and made a decision. The incomprehensible spell was uttered, and Suomen and Mukoni displayed their figures and quickly moved towards the core of the building complex.
But just as the two started, they suddenly sensed something and their expressions changed drastically.
"Be careful!" Suomen shouted.
"Be careful!" Mu Keni also shouted.
The two stopped quickly and tried their best to release the magic shield.
Two energy shields, one red and one basket, quickly appeared in front of them, followed by the sound of "sssssssss" breaking through the air.
"Bang bang bang—"
The energy shield held up by the two men shook violently, and a large number of cracks appeared. It looked shaky, but they still successfully withstood the attack.
Solmen and Mukoni looked at the thing attacking their shields with serious eyes.
They saw that they were several golden ice picks, which were very powerful, far beyond ordinary first-level spells. They hit their shields and exploded, turning into golden ice crystals scattered all over the place.
After seeing it, Solmen and Mu Keni looked at each other. Mu Keni raised her eyebrows and shouted into the night: "Who is it! Come out!"
"Haha, it's me!"
A gust of wind blew by, and a white figure appeared in front of Suomen and Mu Keni.
White boots, white pants, white coat, white hat.
Macbeth!
Macbeth squinted at Solmon and shook his head - he didn't recognize it. Then he looked at Mukoni and nodded - he recognized him.
"Tsk, it's you!" Macbeth said to Mukoni meaningfully, "Let me tell you what's good about you. You escaped before, so why do you want to come to our White Stone Tower again? What? This is our place, do you really think it is your home
By the way, since the last time you appeared, our White Stone Tower has been on alert and directly mobilized one-sixth of its strength to deal with you specifically.
One sixth of the power!
A large group of wizards, including me, are busy every day, just to find you and get rid of you and your companions. It's a good thing you took the initiative to deliver it to my door. Tsk tsk, I really don't know what to say. "
"Just say... 'Too much nonsense, so I'll give you a chance to let you die'!"
At this moment, Suomen suddenly shouted to Suomen, a ball of purple flame appeared in his hand, and he quickly swallowed it into his mouth.
As the flames swallowed him, a powerful aura erupted from Suomen's body and climbed sharply. In an instant, he broke through the first-level wizard and became a second-level wizard.
Then Solmen jumped up, and his whole body "soared" all of a sudden, burning into a slender needle-like flame, piercing Macbeth's eyebrows.
It's an extremely powerful attack once it's launched!
Transformation-type structural spells·Second-level low-level spells·Serving the fire with one's body!
"brush!"
quick!
The flames are extremely fast!
So fast that there is almost no reaction time!
Before Macbeth could close his mouth, with a dazed expression on his face, he was pierced by flames between his eyebrows.
Macbeth swayed and fell to the ground with a "thud", his body splashing into a large cloud of dust.
The flame that pierced Macbeth's brow stopped in the air, fell to the ground, and quickly transformed back into Solmon's body.
Solmon glanced at Macbeth's body with cold eyes, opened and closed his lips, and commented: "Huh, you talkative idiot!"
