After sorting through them, Luo Xinglan found that there were quite a few oxygen cylinders, a total of 150.
However, after checking them one by one, she found that the remaining oxygen in each oxygen cylinder was not much; the least could only support breathing for 1 hour, and the most could only support breathing for 7 hours.
If we calculate based on full capacity, there are only about 30 oxygen cylinders in total.
This quantity is far from sufficient for diving equipment.
We still have to think of a solution.
While racking her brains, she had a flash of inspiration.
There are actually quite a few oxygen cylinders available now; the only shortage is oxygen.
oxygen……
Yes, it can be produced!
She vaguely remembered learning three methods for preparing oxygen in junior high school chemistry: heating potassium permanganate, heating potassium chlorate, and decomposing hydrogen peroxide.
But... does the Sea World have these chemicals?
This is a problem.
Luo Xinglan opened the trading hall and searched for some items, but was somewhat disappointed. She couldn't find potassium permanganate, potassium chlorate, or hydrogen peroxide.
Just like when she wanted to make gunpowder, the sulfur in it was obtained by herself from sulfur soap.
These chemicals simply don't exist.
What other ways are there to obtain oxygen?
She had very little knowledge of chemistry and couldn't think of any other way.
Only then did she realize the true meaning of the saying, "You only realize how little you know when you need to use it."
but……
She's not fighting alone!
Luo Xinglan posted a message on the world channel: "Are there any junior or senior high school chemistry teachers? Please contact me immediately!!!"
This news immediately attracted widespread attention.
"Is this guy looking for middle and high school chemistry teachers? What for?"
"Has another new alien species appeared? And do we need a chemistry teacher to deal with these alien species?"
"My physics teacher disagrees!"
"Ah, my mom's a high school chemistry teacher! Boss, I'll have her contact you right away!"
"I'm a middle school chemistry teacher!"
"..."
Before long, Luo Xinglan had added more than 20 chemistry teachers.
She created a new small group with a simple and straightforward name: "Preparing Oxygen".
Then they added all 20-plus chemistry teachers to the group.
Luo Xinglan: "Hello everyone, I've added you to the group to research methods for preparing oxygen. We can discuss feasible measures together."
Lin Chunhua: "Preparing oxygen? There are three methods at the junior high school level: heating potassium permanganate, heating potassium chlorate, and decomposing hydrogen peroxide."
Luo Xinglan: "Teacher Lin, but these medicines aren't available in the Survival World..."
Liu Jianyu: "Then why not try electrolyzing water to produce oxygen? We have abundant water resources here, and we have a water purifier that can filter seawater into pure water. This method is perfect for us."
Meng Jianguo: "That's right, water electrolysis is indeed a good method that is adapted to local conditions."
Luo Xinglan's eyes lit up: "Teachers, I don't know much about this either, but I can provide you with the venue and materials. You can rest assured to conduct your research. Just tell me what you need!"
Meng Jianguo: "Great! If you can solve the power supply problem, then all other problems will be solved!"
Luo Xinglan immediately had the children take the teachers to "Peach Blossom Spring" Island, telling them to prepare in peace while she went to find the power source.
power supply……
She had left over a lot of batteries from her last modification of electronic devices, so she immediately returned to the armored ship, found all the batteries, put them in her backpack, and delivered them to the teachers.
The teachers then began in high spirits.
Luo Xinglan had nothing to worry about, offered a few words of encouragement, and then left.
Now that the oxygen problem has been solved, all that's left is to acquire as much diving equipment as possible.
She also joined the others in the battle.
Everyone was extremely busy all day.
Around 7 p.m., Luo Xinglan took advantage of dinner to check the number of people in the "Underwater Combat Team," which had exceeded 800.
She had a target of one thousand people in mind, which was already very close.
Then, she asked Sun Zexia about the quantity of his diving equipment.
Sun Zexia had already sorted out all the diving equipment he had received that day, totaling 280 sets and 430 oxygen cylinders, and traded them to her.
Including the original equipment, the total number of diving gear is 380 sets, and the number of oxygen cylinders is 580.
Thanks to the efforts of all the chemistry teachers, the original 150 oxygen cylinders have been filled with oxygen.
Luo Xinglan quickly swallowed the last bite of the sesame seed cake and rushed to "Peach Blossom Spring" Island to deliver the 430 newly received oxygen cylinders.
After returning to the armored ship and resting for a short while, he picked up his meteor hammer and rejoined the battle.
I was busy all day long and didn't have a moment to rest.
The little frog saw all of this.
A hint of sadness flashed across its chubby face.
Seeing this, the little frog quickly asked, "Little frog, what's wrong?"
The frog looked serious: "Lanlan has been working non-stop these past few days, and I'm worried about her health."
Ever since the invasive species began, Lanlan has been extremely busy. It's almost impossible to find Lanlan when it returns from its trips.
It was also sensible enough not to bother Lanlan, but only took the things out of its backpack and put them into the box.
The frog looked at the box, which was so full it could barely close, and sighed deeply.
Sigh, it also wanted to share Lanlan's burdens.
But it can do nothing but travel.
For the first time, the frog began to doubt its own abilities.
The little frog, somewhat helplessly, offered a comforting message: "Little frog, your master is so amazing, she'll definitely get through this..."
The frog said with concern, "I know. But Lanlan gets tired too. She hasn't been eating properly these past two days and has lost weight."
The nobody lowered his head and remained silent.
It couldn't help its owner with anything; it was too stupid.
Just then, the thief and Milk bounced over.
The thief patted the frog on the shoulder: "Frog, do you want to help your master?"
Upon hearing this, the frog looked up at it and nodded very seriously: "I want to, but I don't know how to do anything except travel."
The master thief looked enigmatic: "No, you know nothing about your own abilities."
The froglet asked in confusion, "My abilities? What abilities do I have?"
The master thief glanced at the nobody: "You can summon a higher-ranking frog."
For example, the little transparent one was summoned by the frog.
Its arrival was indirectly summoned by the frog cub.
The froglet was stunned: "Really? How come I didn't know I had this ability? How did you know?"
The thief smiled smugly: "I know this because I am of a higher rank than you. I am purple, and you are green."
The little frog still felt it was unreal and looked at the invisible creature, asking, "Then did you know I have this ability?"
The nobody shook his head, looking completely bewildered: "I don't know."
The two frogs looked at the thief, seemingly waiting for him to explain why, as a nobody among the orange-grade frogs, he didn't know about the frogling's ability.
