In order to avoid drag, one way is to carry all the petri dishes in space iron rings. However, the space iron ring is only one cubic meter, and the internal environment is not suitable for bacterial colony growth and is difficult to modify. If you really put it in, over time, a large number of the cultured colonies will die.
It would be the best solution if there was a portable, large-capacity, and transformable space prop. In this case, it can even be directly transformed into a portable laboratory. Experiments are carried out in it, and if danger occurs, such as explosion, virus leakage, etc., it can be isolated at any time.
But this is just a thought.
As far as we know so far, space props are extremely rare. Except for members of mysterious organizations such as Solmen and Mukoni, no wizard in the entire White Stone Tower has seen anyone possess them.
From this aspect, the terror of the mysterious organization behind Solmen and Mu Keni can be seen.
It's really hard to imagine what the purpose of such a being doing various things in secret is.
Blinking his eyes, Richard recovered his thoughts.
He understands very well that super large-capacity space props are impractical, so he still tries to take it one step at a time. The most important thing is to resolve the cemetery exploration matter as soon as possible.
With this thought in mind, Richard finished operating all the petri dishes, glanced at Pandora who was still intoxicated by the two boxes of glass fragments, shook his head, and walked to the corner. Follow a secret entrance in the corner and walk into the magic laboratory buried deep underground.
The spell laboratory has been renovated again, and there is a huge pool on the ground. At this time, the pool was filled with water, and there was a lot of salt piled in the water.
This is exactly how he made saturated salt water, which is saturated sodium hydroxide solution.
The reason for making a saturated sodium hydroxide solution is...
"Da da da… "
Richard stepped forward and walked to the edge of the pool. There was a strange instrument placed here. Part of it was connected to the pool, and part of it was fixed on the edge of the pool. Next to the instrument, there are many heavy boxes, all of which are lead-acid batteries. They have been fully charged by Pandora during the day, and they have plenty of power.
Richard carried the lead-acid batteries and installed them on the instrument one by one, operated them, and turned on the power.
"Crack!"
Electric current travels through the pool and begins to perform electrolysis, electrolyzing the saturated sodium hydroxide solution:
2NaCl+2H2O= (power supply)=2NaOH+H2↑+Cl2↑
"Grrrrrrrr!"
A large number of bubbles quickly emerged from two different locations in the pool. Richard knew clearly that the bubbles coming out of one location were chlorine gas, and the bubbles coming out of the other location were hydrogen gas.
With a wave of his hand, Richard took out the heavy cylindrical iron can from the space iron ring, used "water droplet condensation" to compress the chlorine gas into liquid chlorine, and put it into the iron can.
This is why Richard made a saturated sodium hydroxide solution—to make enough chlorine gas and then liquefy it into liquid chlorine.
Liquid chlorine is a liquid, and in a sense it can also be called a kind of "water" - well, liquid chlorine water, so what I told Alex about "use iron cans to fill water" was not wrong.
The electrolysis continued, and chlorine gas continued to emerge. Under the control of Richard's magic, the liquid chlorine in the iron tank continued to increase. Of course, it was still far from full.
Richard understood this very well. In fact, the reason why he electrolyzed saturated salt water was not really to fill the iron can, but just to do a test to see how efficient this method of producing chlorine was.
You know, there are many ways to produce chlorine, such as electrolysis of molten salt (NaCl) and magnesium chloride (MgCl). Another example is the use of strong oxidants such as potassium permanganate (KMnO4), manganese dioxide (MnO2), potassium chlorate (KClO3), potassium dichromate (K2Cr2O7) and hydrochloric acid to react with hydrochloric acid to oxidize the hydrochloric acid into chlorine gas.
Of course, the simplest method is to electrolyze saturated salt water.
After all, salt, water, and electricity are enough. Let alone the Middle Ages, even in the prehistoric era, as long as the problem of electricity is solved, it can be carried out in a sea area.
However, there are certain problems with this method.
For example, if chlorine gas dissolves in water, one volume of water will dissolve two volumes of chlorine gas. In addition, chlorine gas will react with sodium hydroxide (NaOH), another product generated during the electrolysis process, to produce sodium chlorate (NaClO3). On modern earth, the diaphragm method is often used to isolate chlorine gas and sodium hydroxide (NaOH) to prevent this situation.
In short, every reaction has advantages and disadvantages. Now he is trying to find the most suitable way to produce a large amount of chlorine gas.
The reason why a large amount of chlorine gas is produced is because...
…
In the blink of an eye, many days passed.
After Richard deliberately succumbed to some special foods and medicines, the orange-red color dyed by Bailang Duoxi on his skin faded a lot. Although there is still a certain gap compared with the normal skin color before, it is still acceptable.
The reason why I say this is because Pandora finally stopped staring at his arm with her head tilted for a long time, and then showed an expression like she wanted to take a bite.
During this period of time, he experimented with various methods of producing chlorine gas and remodeled the magic laboratory many times. Finally, he found the most economical way to produce a large amount of chlorine gas to carry out one of his plans.
…
Late at night, Richard appeared in the cemetery outside Baishi City and walked to the grave of Alex's ancestor.
This is already the third time he has come to explore.
The first time, I got key information from the princess of the Black Holy Mountain Kingdom, Ruth, and came directly to explore. Because I was not fully prepared, I was forced to retreat by the large army of insect swarms.
The second time, I had been preparing for a long time to explore again, and successfully defeated the insect swarm, and killed the two-tailed golden scorpion and the three-tailed crystal giant scorpion. But he never imagined that these were all disguises, and that the real killer move hidden by the tomb designer was the mushroom spores in the microscopic world.
This was almost a cross-dimensional blow. Even if he had considered it, he was not prepared for it—he was truly hit. If it weren't for the presence of Bailang Duoxi, he might have been completely cold.
Now he finally recovered and began to prepare for his third expedition.
But this third expedition, he didn't want to be the same as the previous two.
From the previous two times, he had almost known some of the conditions of the tomb, and was extremely vigilant about the unknown things deeper in the tomb.
According to the inherent routine of tomb designers, things deeper in the depths will definitely be more deadly and more difficult to guard against. There may be a second or third insidious method like mushroom spores.
Even if not, the mushroom forest and the new insect swarm army in green, red and purple colors are not easy to deal with.
Therefore, he really didn't want to take the same adventure as before and then suffer a loss.
In this cemetery, if he falls once, he is unprepared; if he falls twice, he is careless; if he falls three times, he has no brains.
Since the designer of the tomb had set up many insidious means, he didn't mind using some unconventional methods to clean up the tomb.
If you are unkind, I will be unjust.
If you are infected with germs, then I will disinfect it vigorously.
You have planned many difficulties, so I will simply... violently demolish it.
Exploration, adventure, the premise of adventure is that there are "risks". If all the "risks" are eliminated, then there is nothing left to explore, it can be pushed forward directly.
Richard thought so and narrowed his eyes. The next moment, he bent down and activated the "Earth and Stone Control" to create a downward passage in the ground. Then he took out the heavy, cold sealed iron can from the space iron ring, pointed it at the downward passage, and opened the lid with a "bang".
The liquid chlorine inside, which is in a high-pressure and low-temperature state, quickly vaporizes when it comes into contact with the outside world. It turns into yellow-green chlorine gas with a strong pungent smell and shoots out, rushing towards the channel crazily.
