Mage? Spell Engineer!

The end of the civil war is in line with the expectations of the majority of "Smurfs" for peace and stability, and has laid a stable foundation for the further development of the tribe in the future. The flesh and blood picked up by the jets and villains will soon become "delicacies" at the celebration banquet.

The elder invited the two to attend the banquet, but Rorschach decisively refused.

"There's still some time before we return. Can you accompany me to the upper floor to take a look?" He invited Caroline.

"certainly."

The two nested the [Levitation Technique] again, and Rorschach used the [Air Cannon] to push back the gas under him to climb into a thinner atmosphere. After sprinting at high speed for about a quarter of an hour, Rorschach could feel his whole body getting colder, and [ The effect of the underwater breathing] spell is ineffective.

The thinner the oxygen in the atmosphere, the less the spell can concentrate to breathe, and it does not open up other gases to enter, so it becomes increasingly difficult for Rorschach and Caroline to breathe.

When he had almost reached the limit and the little people below were like ants, Rorschach stopped sprinting. He no longer spoke anymore, and instead used [Communication Technique] to communicate with Caroline: "Can I trouble you to carve out a space and don't let the air circulate?" ?"

This is not difficult for Caroline, especially in a space that is open enough and only filled with gas, without the interference of condensed matter. Soon a small transparent rectangular space appeared between the two of them, blocking the flow of air inside and outside.

Rorschach took out a compressed gray cylinder from the ring, like a candle. He handed it to Caroline and asked her to put it in an isolated space and light it. After Caroline did so, the "candle" gave off bright light and puffed out smoke, which looked a little yellowish-green if you looked closely.

"Be careful, there may be a risk of explosion."

The candle burned inside for a while. As soon as Rorschach finished speaking, fire suddenly erupted, and the ether membrane that isolated the space was instantly impacted. Caroline almost lost her balance.

"What is that?" Caroline mistakenly thought it was Rorschach's candle exploding.

"Generate a candle that requires phlogiston." In fact, it was an oxygen candle that Luo Xia made temporarily. Although he entered the air element plane out of curiosity, it was not that he rushed in unprepared. In order to prepare for [underwater breathing] 】When the spell doesn't work, he prepares oxygen candles in advance.

When the raw materials of the temporarily rubbed oxygen candle are burned, in addition to releasing oxygen, it will also produce chlorine, a fatal by-product. This is also the source of the yellow-green color. Although Rorschach does not have barium oxide that can absorb chlorine and can be mixed in, Faye has [ Air filter bubble] to isolate harmful gases!

Of course, Master Fa's [Underwater Breathing] is also effective, so this time the oxygen candle was used to verify one of Rorschach's conjectures. He noticed that when the pterosaurs fled, they would fall when they reached a certain height. He guessed that the oxygen in the upper layer was thin.

Just like the increase in altitude and decrease in atmospheric concentration on the main plane, the stratification effect of various gases on the air elemental plane is more obvious. Now they are in an environment dominated by light gases.

Put another airbag in, and the volume of the airbag becomes larger, indicating that the gas in the ether membrane space has become less. Rorschach speculated from the short burning time and rapid explosion that part of the atmosphere is now hydrogen with a low explosion limit, and the rest does not matter. Is it helium, or is it a gas exclusive to this plane? In short, it has superior properties:

Incombustible, lighter than the air of the Prime Material Plane, much lighter.

Rorschach finally explained to Caroline what the series of "little alchemy experiments" were doing. Caroline suddenly realized: "So the gas here can be used in the airship."

"Yes, it can greatly improve the safety of airships." Rorschach also remembered that Teacher Caroline was born in Valois. He was not sure whether Caroline knew about the empire's reliance on airships, so he added: "Of course, the main thing The purpose is still in production.”

There is a clear interface between the top layer with thin oxygen and the shallow layer where the "Smurfs" live - the hydrogen gas in the top layer and the oxygen in the shallow layer merge here. When the charge generated by the friction of the air mass is released and the mixture is ignited, a large amount of Water vapor, so when you look down from below, you can see the white clouds at the junction layer, and the top layer is directly connected to the starry sky.

Lack of oxygen is not a pleasant thing. After the two verified it, they immediately dived back to the sewage outlet. Regarding how to transport it, Rorschach had an idea: "Teacher, you taught me the principle of [water creation], right?"

The other party immediately understood Rorschach's intention: "Summoning water from the water elemental plane, do you want to draw light energy from here by analogy?"

"Yes." The pressure of the air elemental plane is already lower than that of the main plane, not to mention that the light air is at a lower pressure level. If you use the reverse direction of the sewage outlet to extract the gas from the air elemental plane, it will be very uneconomical and laborious. Compared with sewage discharge, the transportation volume of extracting gas to meet the needs of industry and airships will be much larger, and the material and energy costs of maintaining the portal will soar.

The most economical method, which is also not afraid of the intrusion of creatures from the air elemental plane, is to construct a gas-extracting spell similar to the [Water Making Spell].

"It's a challenge, you can try it." This was related to Caroline's field. After the construction of the mage tower was completed, she was in need of a new topic, and the idea proposed by Rorschach was in line with her direction and interests.

When they returned to the tribe, the banquet had already begun. There was no condition to light a bonfire here, it was just for everyone to have a "good" meal. But the elder brought a "surprise".

"Sir, in order to express my gratitude, I present to you the most beautiful thing from our tribe."

"Stop it!" I'll go, you use this to test the mage? Rorschach was face-blind, and he couldn't even distinguish the gender of the villain presented by the elder. He could only tell that it was indeed much prettier than the old man.

Caroline looked at her students with a playful expression. Rorschach finished criticizing the elders righteously, and the time agreed with Hannah came. Caroline opened the temporary portal, and Rorschach fled.

"Sir, didn't you say that all mages love beauties? Why did you reject our gift? Is the mage angry?"

The elder had a face on his face and repeated Luo Xia's words to reprimand the patriarchs of the two major families, even though he had come up with the bad idea in the first place. The heads of the two major families nodded in agreement, but their eyes changed when they looked at the elder.

A few years later, the growing "Devourer" clan secretly circulated the top ten wildest unofficial histories. The first one was "The Master Mage doesn't like beautiful women. The first leader of the tribe, the Great Wise King, was sold to two Masters of the Mage." He started his business in Gouzi.”

Rorschach still didn't know that his refusal to give the gift had caused the elder Feng Ping to be killed for no reason. Caroline, who came out of the portal, was still teasing: "That little thing is quite smart, why don't you accept the gift and become a servant?"

Why do you sound so weird when you talk? Rorschach explained seriously: "The creatures in the air elemental plane are relatively fragile, especially those little blue people. They may have various physical problems when they come to the main plane. Besides, what servants do I want?"

The initial exploration of the air elemental plane is over. Caroline goes to rest first and wants to study [Qi Creation Technique]. She may have to go back and forth between the two sides in the future. Hannah returns to her internship.

But Rorschach couldn't rest yet. He packed his bags and prepared to meet the prime minister Otto, who had been waiting for a long time.

“I don’t know if Andre and Bart are doing a good job in reception.”
