After meeting Archmage Strachey and successfully obtaining the Royal Mage badge of Archmage Straych, under the guidance of Queen Dorothy, Xia Lin quickly mobilized thirty three-ring royal mages in the Royal Magic Guard who were proficient in the plastic energy system.

Any mage is reluctant to act as a mason, but since they have been provided for by the royal family, they naturally have to obey the royal family.

After learning that Xia Lin was the founder of the "Rune Variants and the Four Basic Rune Theories" that shook the three major magic societies in the Imperial Magic World, the thirty royal mages also put the masons behind and began to ask about the specific derivation process of those strange mathematical symbols.

From their mouths, Xia Lin knew that many of the ancient magic societies that had been circulating in the wizarding world had not died out, but had become stronger and stronger with the passage of time.

The Eyes of True Knowledge, Spell Wisdom, and Rune Mysteries mentioned by Master Flynn in his words before are the three largest magical associations in the Empire, and Xia Lin just met Archmage Strach, who is the current president of the Eye of Knowledge.

Thinking about it this way, Xia Lin suspected that the reason why Archmage Straitch insisted on seeing him just now might also have the idea of wanting to join the Eye of True Knowledge Magic Society, but he didn't mention such a thing at all in Shicai's conversation, maybe Xia Lin was too self-inflicted.

With thirty three-ring mages and a temporary construction team to the R&D center that had only completed the land leveling and the establishment of a simple wooden house, Xia Lin took out the architectural drawings he had drawn, and explained the architectural requirements of the R&D center and Carl's laboratory to the mages who were one ring higher than him.

The mages were very capable of understanding, and although it was the first time they had seen such a drawing, they soon understood Xia Lin's request.

In order to ensure the strength of the building, Xia Lin asked the construction team to tie up the steel bars produced by the steel processing plant in advance to form the skeleton of the building, and then a rare three-ring mage took turns to cast spells, and the already compacted and hard soil turned into something like fluid.

With the control of the spiritual power of the mages, they climbed up to the steel cages, and then formed solid pillars and walls under the effect of turning mud into stone spells.

After thirty three-ring mages took turns to cast spells, the two thousand square meters designed by Xia Lin included a series of factories, laboratories, researchers' residences and various living facilities, and the six-story business alliance R&D center was completed in just one afternoon.

Xia Lin, the construction team, and the ten-person security team in charge of security in the R&D center were all shocked when they looked at this terrible progress.

Going in and knocking on the thick walls, the strength of the gray rock converted by the magic power can at least be compared to the granite, plus the reinforcement of the steel inside, I am afraid that even if it is bombarded with an 80 caliber breech gun, it will only shatter some of the surface stones.

This kind of strength can fully meet Xia Lin's design requirements, which makes Xia Lin have a deeper understanding of the power of magic, and he can't help but think about how good it would be if the workers of the First Construction Company were all three-ring plastic energy mages.

However, these are delusions, after three days of non-stop spell bombardment, the R&D center and the main body of the Karl Research Institute, which is located about one kilometer west of the R&D center and is built in the same way, covering an area of about 800 square meters, with three floors above ground and two floors underground, with a total of five floors.

Her Royal Highness sent three court alchemists at the right time to set up many magic traps for the R&D Center and the Karl Institute, many of which were hidden traps that could not even be found if Xia Lin had not looked at the drawings provided by the alchemist.

All that remains is to install the machinery and equipment and renovate it so that it can become a permanent home for hundreds of researchers in the future.

In order to thank and win over these high-ring mages, Xia Lin specially sent ten red envelopes of gold lunt to each of these mages, and in the news that Xia Lin inquired, these gold lundes were not a few.

The mages of the Royal Magic Guard have an allocation of almost 120,000 gold lunts a year, which is about 10,000 gold lunds a month, and the royal magic guard has a total of 183 members, and on average, each mage gets it

It's only 55 gold lunt, which is not as good as the three rings, but there is also a part-time alchemist and golem expert Sophia Hirst.

After the mages who had received the windfall income left satisfied, Xia Lin checked the quality of the work and was satisfied with the hard work of the mages.

In particular, the living demonic beast preservation room that Xia Lin set up in the two underground floors specially requested by the Karl Research Institute was surrounded by walls of steel demonic rock that were half a meter thick.

Xia Lin also planned to lay three more layers of 40-thick steel plates on it, and then use isolation runes to isolate the magic inside the preservation room, so that the demonic beasts captured by the adventurers would not have the slightest chance of escaping.

Although it costs a lot of steel, it is worth it for the safety of the most valuable researchers at the Carr Institute.

After completing the two buildings that were crucial to both the Alliance and the New Leaf Chamber of Commerce, Xia Lin immediately arranged for Sophia to live in the Karl Institute, and she had already made fifteen rune disks for purification, and according to her estimates, the cost of each rune disk was about two gold lunt and thirty-seven silver mar.

As a rune plate for a ring of spells, the cost of the purification technique is not high, and Xia Lin guesses that it is probably because this spell model is too simple.

With these rune disks, Xia Lin came to the industrial park, and the machining factory had already processed the large conjoined jars he needed, each jar was half a meter in diameter and one meter and two meters high, and the middle was connected.

Xia Lin tied the rune plate inlaid with magic stones with a rope and put it in the same jar to cover the lid, and the next thing was to see if this purification technique could realize his idea.

After Master Faun left the industrial park to lead the gun factory in the R&D center, Master Halle Limestone became the temporary director of the machine tool factory and the machine factory.

"Boss Xia Lin, what new gadgets have you come up with again?"

"Probably!"

Xia Lin nodded uncertainly, and after about a few minutes, the duration of the purification technique had ended, and he had the lid opened, first taking out the string of valuable rune plates, and then lighting two candles, tied them with ropes and put them in two jars.

The subsequent phenomenon made Xia Lin frown, and the burning state of the candles on both sides of the jar did not change significantly, which was not in line with Xia Lin's expected experimental phenomenon.

What's wrong with that?

Xia Lin carefully iterated through the principles of the experiment he had designed, using the purification technique to give the gas molecules different speeds, so that they could be separated in a conjoined tank......

Wait a minute!

Xia Lin realized a problem, could it be that the jar he designed was still too small, so after the action of the Purification Rune Disk, the main component of the air that had already been separated was mixed with nitrogen and oxygen again?

Referring to the sand experiment he had done before, Xia Lin suspected that this was the problem, and he repeated the sand experiment and found that under the effect of the purification rune disk, the sand and soil still appeared to be clearly stratified according to the different internal components.

Obviously, his guess was most likely the reason, Xia Lin thought for a while about how to solve the problem of air separation, and finally asked people to go to the textile factory and the paper factory to get some linen and A1 standard paper that had not yet been cut, and use glue, bamboo and lacquer to make them into sealed long cylinders.

This strange long tube is 10 long, 1 wide and 1 high, and Xia Lin evenly distributes the Purification Rune Disc in the first half of the long tube.

After a minute or two, he placed a candle in the middle and a candle in the back through the opening he had reserved beforehand, but this time the result was satisfactory to Xia Lin.

The flame of the candle in the middle burns much brighter, and the candle in the back burns much weaker.

Needless to say, the purification must have caused the components of the air to move at different speeds, so that most of the oxygen molecules with relatively larger molecular mass stayed in the middle section, and the smaller nitrogen molecules were accumulated in the second half of the cylinder, reducing the oxygen concentration in it, so this situation occurred.
