Philip smiled bitterly: "Robert, this guy has recently been working on a potion that is said to be used to produce a very powerful explosion in a tough battle, but it doesn't seem to be progressing well." ”

Leo had heard of this kind of potion, and he couldn't help but guess in his heart whether it was a fiery potion, or a crushing potion, or some other potion that he didn't know.

The door to the laboratory opened, and a cloud of black smoke wafted out with the pungent smell of gunsmoke.

"Who!who allowed the door to be opened!" Robert's excited growl rang out.

"Calm down, Robert! it's me!" Philip shouted, leading the way inside.

Looking at the black smoke in the laboratory, Leo wanted to cast a "wind dance" to purify the air, but after thinking that there might be a lot of special materials that were very sensitive to magic fluctuations, he immediately gave up this idea and followed Philip into the laboratory despite the pungent smell.

Although through the black smoke, Leo still noticed at a glance that the overall structure of the laboratory had not changed much, and it was still the same as before leaving, which made the feeling in his heart a little more complicated.

"Click. With a crisp sound, the window opened. The air movement from the outside world has been close to it, and the black smoke has been cleared in the blink of an eye.

Robert looked very bad, his eyes were bloodshot, his hair was burnt in large patches, and he looked in a very bad state. Even Leo's appearance didn't make him have much change in mood, just nodded and greeted him casually.

However, Leo found that the yellow mage robes he was wearing had been successfully promoted to the intermediate level.

Seeing him like this, Philip sighed and said, "Why are you doing this, we didn't ask you to do this, you just need to ensure the production of the essence of the Storm Wolf bloodline." ”

Robert immediately shook his head and said, "You don't understand, Uncle Philip. Making the Storm Wolf Blood Essence is just my job. But researching Thunderbolt Elixir is what I'm pursuing. ”

"But look at yourself, I'm really worried that when I open the door of the laboratory that day, I'll see a cold corpse!" Philip said bitterly, "I don't care about your own safety, but I have to care about your safety! After Uncle Byron left, the lab was left to your own devices. If something goes wrong again, what will the family's Storm Warband use to replenish and maintain?"

There was a slight pause. Philip raised his voice again, almost roaring, "Listen boy! You don't understand your own importance! What you are doing now is irresponsible to the whole family!"

Robert was speechless.

But soon, to the surprise of Leo and Philip, Robert's eyes quickly regained firmness, and he said-for-tat: "No! Uncle Philip! I will definitely not give up! Even if you expel me from the family, I will never give up! I have been preparing for so long and trying so many methods. Maybe the success will be next time! As long as I can develop a thunderbolt potion, my name will go down in the history of magic, that's what I want! Maybe when I'm older, I'll work for the family in peace. But not now, absolutely not!"

"You...... You ......" Philip pointed at Robert, his fingers trembling with anger.

Seeing this scene, Leo had no choice but to stand up and play a round: "Actually." There wasn't much conflict between making the Storm Wolf Blood Potion and Robert's personal research. However, when designing experiments, more attention must be paid to the control of safety. Robert, can you tell me about your idea for the experiment? I'm curious about it. Of course. I can make a magical oath that I won't leak or plagiarize anything. ”

Although he didn't quite agree with Robert's lethal behavior, he had to admit that magic could develop precisely because there were too many people like him. For example, the teacher Byron, such as the tutor Geralson in the academy, are all such people who can give everything for the study of magic.

With that in mind, Leo certainly didn't mind giving some advice on Robert's experiment. And it was not so much that he was moved by Robert's spirit as it was that he respected this belief in the pursuit of truth.

"No need to swear an oath, I'm sure you're not that kind of person. Robert replied, and then handed Leo a thick stack of lab notes.

Although in his memory, Leo was still the child who had just left the family and was about to take the joint entrance examination, and it was impossible for him to have any superb attainments in the study of magic. But because his long-term experiments did not go well, he was looking for someone to talk to, and some of the ideas of other people may really bring new ideas.

Anyway, the cat is already blind, what if it does hit a dead mouse.

Philip was rude, but that didn't mean he didn't see the situation, so he didn't say anything more.

Taking the note, Leo flipped it from the beginning, but the surprise on his face became stronger and stronger, and he unconsciously muttered a word: "nitroglycerin?!"

"What?" asked Robert, of course, not understanding what he was saying, curiously.

"Nothing, my personal habit. Leo replied casually, continuing to look through the notes in his hand.

He read very quickly, and after a few minutes, he read the notes roughly, but he did not communicate with Robert immediately, but pretended to continue reading while thinking in his heart.

Judging by the current situation, Robert's experiment is quite mature, and nitroglycerol is synthesized.

In fact, in this world, nitroglycerin has actually been synthesized by mages for a long time, but because there is no complete chemical system, this yellow oily substance is simply called yellow frying oil.

According to Leo's understanding, this very dangerous chemical has the risk of explosion when exposed to extreme cold and heat, impact, friction, open flame and high heat. Contact with strong acids can also cause a strong reaction, causing combustion or explosion.

So, the mage who synthesized it in the first place, after announcing his results, tossed them aside. Later researchers, most of them, gave up quickly after a little attempt.

Because no one wants to be exposed to this uncontrollable dangerous goods too much, once they don't do it well, they are likely to die in the experiment.

Glancing at the vial containing the yellow oil on the bench, Leo shuddered and had the idea of leaving here quickly.

Fortunately, Robert seems to have added several defensive magic arrays to his experimental range, otherwise the explosion just generated would not only be thick smoke, but might have blown the castle into the sky. (To be continued......)
