It's like a minesweeper game, the more you get to the later stage and figure out the more rune effects, the smoother Xia Lin's research progresses.

But there was still one kind of rune in Xia Lin's hand that he couldn't figure out the specific use, that is, another type of rune with a wide variety of unknown types that constituted the soul core.

However, Xia Lin guessed that this rune should be related to the intelligence possessed by the soul core, so he named it the logic rune, and planned to study it in the future.

It took twenty-five days to complete a series of complex researches, and the moment Xia Lin announced the end of this project, it was like a lifetime away, and he even read the final report several times with some uncertainty.

Finding that his research results were indeed in front of him, that there was no error in the logic of the experimental phenomena and the derivation process, and that there were no errors in the data based on the topic of "Mathematical Modeling of Rune Spiritual Power Nodes", Xia Lin accepted that he had become almost comparable to Mendeleev in the magical world.

Of course, this is only the height that Xia Lin thinks this theory can reach, and if he wants other mages to agree with his contributions, he must at least wait for this theory to be verified by various runes that Xia Lin has not yet touched, and at the same time let it really play a role in the wizarding world, and then wait for someone to write a history of magic.

"Everyone has worked hard during this time, but I believe that everyone's harvest should be great, with this rune variant and the four basic rune theories, I think the difficulty of teachers learning new runes will be reduced by at least two or three levels.

In order to repay your efforts, the previous rune spirit power node mathematical modeling project and the four basic rune theory topics will be given to the team members with a bonus of 5 gold lunt! The prize for each research team leader is 10 golden! ”

Xia Lin stood at the desk and looked around at the immature but accomplished faces of the researchers in the laboratory, full of emotion, patted the final report on the table and continued:

"But there's one more thing you need to work on, and that's to study the rune connections in the spell model, and try to build a ring spell with clean runes!

After completing this round of research, we at Karl Lab can be regarded as filling in this indispensable cornerstone of magical research for the wizarding world, and the magic we design ourselves may not be impossible to achieve.

Such results will definitely be recognized by the wizarding world, so everyone work hard and do it well!

When the last topic is over, I'll cook a big meal for you! When you graduate, you'll get the same conditions as Luna! As for Luna, your treatment in the lab will also be improved! ”

"Boss, do you really know how to cook? If the dishes are not delicious, it is better to send us a few Jinlunt to bake a fork and eat it! ”

Lamb Hubert, the interim researcher, said with a wink, causing a group of children around him to laugh.

"Don't worry! The famous Carl Cake Shop on Silverfish Avenue in the North District is an industry under my name, do you think my craftsmanship will be poor? When the time comes, beware of swallowing your tongue and becoming mute, don't blame my Carl Lab for not recruiting disabled researchers! ”

Xia Lin laughed and patted Lamb on the shoulder.

This guy is the first batch of people who came to the stage to receive the test papers, he is bold, active, and talented in mathematics, Xia Lin thinks he is very good, and when the laboratory expands into a research institute, maybe he can serve as a deputy director.

After some more confidential questions, and sending these children away, Xia Lin did not rush to the academy to talk to Dean Manan about cooperating in the creation of the mage journal, but returned to his room, preparing to start the promotion of the second ring mage.

After this period of training, Xia Lin's spiritual strength has grown to more than 400 meters, and his research on runes has also produced some results, and he wants to see if his research results can help him go further on the road of magic.

Standing by the window and stretching comfortably, looking at the trees outside the laboratory window with more and more withered leaves, relaxing for a while, and putting himself into a better state, Xia Lin suddenly felt something:

"It's already autumn!"

Recalling some of the things he had done since he awakened the memories of his previous life, Xia Lin found that the circumstances of his life were really wonderful.

However, in just five months, he created an industrial park, and more than 1,000 people under his command had to rely on themselves to live, and at the same time he also became the trusted confidant of the imperial daughter, occupying a fairly high position among the enlightened faction of the great nobles of the empire.

Now, relying on his own research ideas, he has picked up the largest and most colorful shell on the magical beach.

After a short period of emotion, Xia Lin thought back to himself if there were any omissions during this time, and found that the situation was not bad, and then he stopped thinking about these meaningless things.

Taking out a two-ring scorching ray spell scroll and sitting by the window, Xia Lin silently began to memorize the spell model on it.

In the spell hierarchy, a rune has 15 to 30 spell nodes, and a zero ring spell consists of 2 to 4 runes, with an average rune node count of about 60.

A ring spell consists of 5 to 9 runes, with an average rune node count of about 140; Two-ring spells consist of 11 to 17 runes, with an average rune node count of about 300.

The number increase is exponential, and the difficulty increase is exponential.

If you rely on traditional rote memorization and repeated spell casting, if you want to break through from the first ring mage to the second ring, even if it is the intelligence of the mage, it is basically impossible to do it in a few years.

However, Xia Lin was now quite familiar with the fire runes, mana matter runes, and template runes that constituted the scorching rays of the two-ring spell, as well as the index rune groups composed of spiritual power simulation runes, kinetic energy runes, and preservation runes, and he could recite almost every rune node position in it.

The difference is simply to be familiar with how the runes are connected, and to try back and forth within the approximate range of node coordinates when building a spell model.

After all, there is no ruler compass when building a spell model, and although there are coordinate points to narrow the margin of error, it still needs to be tried.

Although the help of the node coordinates reduced the difficulty of learning the Second Ring Spell, it was not until half a month later that Xia Lin successfully used the Scorching Ray for the first time.

With a violent fluctuation of magic power, Xia Lin hurriedly used his mental power to control a blazing white light into the air, and that white light did not slowly dissipate until sixty or seventy meters away.

However, in just half a second, even the wooden window of his room had a scorched yellow mark of smoked wood, and while he was happy, Xia Lin also felt a little apprehensive about the power of the scorching ray of the second ring spell.

With such power, even a knight in plate armor may not be able to help it, no wonder the mage has such a lofty status in this world, but I don't know what kind of power the fireball technique of the three rings is, is it more powerful than the 155mm howitzer shell?

Within 10 meters, all minced meat, 10 to 20 meters, either death or serious injury?

Shaking his head to shake the thought out of his mind, Xia Lin continued to practice.

After successfully casting a spell once, he grasped the key to building a spell model, and Xia Lin succeeded again in the next day's practice.

After another five days, the commercial banks located in the four regions of the imperial capital have been officially completed and started operating, the funds for the R&D center have been in place, and Xia Lin has finally stabilized the success rate of the scorching ray's spell casting to more than ninety percent, and has officially been promoted to the second ring mage.

Two months before graduation, Xia Lin passed the first ring mage certification of the mage guild, and now it has only been more than half a year, and he has broken through to the second ring.
