In Violet Castle, Karin and Khadgar were studying, as usual.

As Carlin waved his staff, a pale green glow enveloped him, and the arcane energy around him seemed to be stilled with the light!

"There's a little bit of a problem, Karin!" A peaceful voice.

Carlin put down his staff and listened quietly to his mentor's teachings.

"The essence of 'Spell Void Enchantment' is not the same as 'Spell Counter'...... Don't stop at the logic of inertia! The latter release object is your confirmed target; And the former, to the future mimic target as the object! ”

Archmage Antonidas is not stern, but rather patient!

In fact, several of his students have very good comprehension, and they don't need much explanation from him.

"If you want to use a future mimic target, do you want to use prophecy spells to clarify it?" Carlin seemed to understand a little.

"Well, that's the right idea!" Antonidas nodded.

But he didn't seem to have time to explain further...... An owl, bringing a letter, threw it in front of him.

"Maybe I need to leave!" Antonidas's face changed slightly, and he turned to leave.

As the supreme ruler of Dalaran and the most powerful mage, Antonidas was busy...... Both on the work side and on the research side! Of course, even so, he often takes a little time to guide a few students.

And for this kind of thing, both Carlin and Khadgar have become accustomed to it.

The moment the instructor left the training ground, Khadgar jumped to his feet...... He stretched lazily, as if he had been holding back for so long.

Looking at Carlin, who was still thinking there, he said a little boredly: "Carlin, will you not rest?" You've been practicing like this all morning. ”

Carlin ignored him.

At the same time, another owl flew in and threw a note to the ground.

Khadgar picked it up and glanced at it:

"Carlin, there's your letter, from the alchemist Vadla, he seems to be waiting for you at the gate of the castle!"

……

Carlin walked out of Dalaran Castle and saw the Vadra, a six-ring mage and a good accomplished in alchemy!

"Hello, Master Carlin!" Because of Karlin's identity, the other party's attitude was very polite: "What I was asked to configure last time, I have already figured it out!" ”

As he spoke, he handed over a small bag of something that was very well sealed.

"Okay, thank you......"

The bags were filled with a yellow, oily, transparent liquid that was divided into many pouches.

"The way you say, when glycerin is treated with a strong acid, it does produce this liquid that is very unstable...... After hundreds of experiments, we have come up with the optimal solution. The recipe data is also in the bag! Alchemist Vadra introduced.

"Well, I'll take a look at ......"

"Be careful, these liquids can easily expand violently and produce a large amount of fire element......al after being exposed to external stimuli," Vadla continued to remind, "Now that we use the Spatial Compression Spell to suppress its liveability, it will not be dangerous for the time being. ”

"But when using it, try to release a protective spell as much as possible!"

"The higher the level of the protective spell, the better...... In addition, the total cost of 32 gold coins has been credited to the research bill of Lord Antonidas. ”

"Excuse me...... If there is a need for alchemy next time, I will look for you! ”

……

After thanking Vadera, Karin took the entire bag back to his room.

"Carlin, what is this?" Looking at Carlin with something in his hand, Khadgar suddenly became energetic.

"Don't mess around, go and call Kel'thugad!" Carlin said hurriedly.

Khadgar soon brought Kel'thugad over.

"What's the matter?" Kel'thugad was as concise as ever.

"Kel'thugad, I need you to help me with one or two defensive spells!" Carlin pointed to the bag on the table and said briefly, "This is the research topic I asked my mentor for: 'Exploration of Enhancing the Power of Flame-based Plastic Energy Spells by Increasing Phlogiston Concentration'!" ”

"That's how you defeated Khadgar in the fourth ring when you were in the third ring?" Kel'thugad was also immediately interested.

Kel'thugad picked up his staff and stood beside Karin.

"What the hell are these?" Khadgar asked, curious.

"Pure glycerin extracted from black mouth fish oil, the product of strong acid treatment...... I'll leave it to the Alchemy Workshop to help with it! Carlin smiled and said, "You can call it 'nitroglycerin'!" ”

"Looks expensive!" Khadgar's interest suddenly deepened.

As he spoke, Carlin carefully tore open one of the small bags of nitroglycerin, and then threw it forward, and the liquid inside flowed out.

Kel'thugad's shield enveloped the bag, and only a somewhat muffled explosion was heard.

"That's pretty good!" He frowned and commented, "I think I can easily break through the ordinary defensive spells below the third ring!" ”

"Okay, a simple physical explosion is only less than ten percent more powerful than concentrating its power into the spell by increasing the concentration of phlogiston in the surrounding area...... "Then it means that with nitroglycerin as the primer, there is a possibility of releasing the five-ring 'Flame Blast'!" ”

……

For an entire night, the three of them were conducting experiments in the training ground.

Protected by Kel'thugad's protective spell, Carlin didn't have to worry about nitroglycerin hurting him.

However, it is still difficult to calculate the phlogiston concentration required for the Flame Explosion Technique...... At the same time, because nitroglycerin itself is strongly unstable, the failure rate is very high, and continuous repetitive tests are required.

Just when Khadgar was a little tired and ready to go back to sleep.

"Wait!" Carlin whispered.

A large meteorite-shaped fireball appeared at the top of his staff.

"This is the 'Flame Explosion Technique', Five Rings!" Kel'thugad narrowed his eyes and said with a serious expression, "Although the power is weaker than that of the 'Flame Explosion Technique' released by the ordinary Five Ring Mage......"

You know, Carlin is just a four-ring mage......

However, Carlin seems to have a hard time handling this huge fireball...... Half the distance of the forward projection, and it falls!

"Still failed!" Khadgar shook his head in disappointment.

"At least that's a good start...... Carlin began.

"And, an amazing find!" Kel'thugad added.
