Judging from the experimental records, what Robert wanted to do was to find a safe production method for nitroglycerin and a controllable detonation method, but there were still some deviations in some specific details.

Leo knew very well that even the slightest change in modern chemistry experiments could lead to completely different results, so Robert's experiments never made any new progress.

In a completely unknown situation, it takes a little luck to find the final result, and people who have no luck are likely to spend their entire lives and not succeed.

However, this is not a problem for Leo, although he does not know the process, but he knows the result, and he can deduce the process from the result, which makes it much easier, and he will definitely be able to get the most correct conclusion.

It's just that......

Leo believed that he could make that terrifying explosive if he wanted to, so much so that he wasn't sure if he should release the whole horrible monster. Because in the previous life, this kind of explosive substance with extremely powerful power saved a lot of manpower while also taking the lives of an unknown number of people.

Fortunately, another monster, the strategic HE weapon, is still a long way from the development process of this world, and because of the existence of magic, perhaps such a complex weapon will not necessarily be taken seriously.

Seeing that Leo didn't move for a long time, Rotber asked anxiously, "What's wrong, what's wrong?"

"Uh...... Wait a minute, let me take another look. Leo hesitated, unable to make a decision for a moment. At this time, there was a knock on the door of the laboratory.

"What's the matter today, come in, the door is unlocked!" Robert said in a somewhat impatient voice.

The door opened, and an attendant walked into the lab with three children.

Robert wondered, "What are they doing here? Didn't I tell you that their souls are not yet fully formed, and they can't do magic training, they can only get in touch with some basic knowledge!" Just find a scholar, don't bother me every day!"

Only then did Philip remember that there was still a matter of testing his talents, and he stepped forward and explained: "I called them here, and Leo rarely comes back, so I want him to help see how these children's talents are." ”

"Oh!" said Robert, visibly upset. However, it was only when he remembered that Leo was the fourth in the national magic joint examination that his dissatisfaction gradually subsided.

Maybe people's strength and rank are not as good as their own. But the talent is much stronger, and of course there is the right to re-examine the talent of these children.

The three children, two boys and one girl, all eight or nine years old, looked at the people with fear in their eyes, and they all hid behind the attendant, not daring to show their faces.

Philip smiled and introduced: "They are all children of ordinary lords, they have never been far away before, and they rarely see living people, and they are a little timid. ”

Leo nodded. Putting aside Robert's experiments for a moment, I turned my attention to the children.

In terms of age, eight or nine years old is the best grade to start learning and mastering words. Learn basic mathematics knowledge and exercise correct thinking and behavior habits.

Large families tend to cultivate talents from this age, and although the Joseph family has been in a relatively declining period of magic recently, they are also aware of these basic common sense.

Looked at Robert. After confirming that the other party did not cause much unhappiness, Leo asked, "How did you conduct the test before?"

Robert replied as a matter of course, "Native Spiritual Power Level." Is there any other way?"

Leo didn't answer his question, but continued, "How are the three children's original energy and mental power?"

Robert didn't ask, but introduced: "It's not bad, the girl on the left is called Harry, the level of native mental power is excellent, the boy in the middle is called Thomson, who is also excellent, and the girl on the far left is called Erin La, who is the best among them, the best level." ”

According to the universal standard, people's original spiritual power is divided into average, better, excellent, excellent, excellent, and superb.

And the minimum requirement to become a mage is excellent. Although ordinary and good spiritual power is not absolutely impossible to become a mage, but the innate strength is insufficient, and it cannot be effectively controlled at all, maybe after trying uninterrupted for a few years or more than ten years, there will be a chance to successfully enter the meditation state and enter the door of magic.

To be able to have excellent native spiritual power, there may not be one in hundreds of children, and the best is very rare. It can be said that all three children do have the qualifications to be trained to become mages.

Leo's gaze swept over the faces of the three children one by one, and then he spoke: "The original spirit power test is very mature, and I also believe that Robert will not make a mistake in this kind of thing, so there is no need to re-test." ”

"Uh......"

Hearing him say this, Philip couldn't help but be greatly disappointed.

When Robert saw that Leo seemed to have something to say, he asked, "So what do you want to do?"

"Let them try some simple problems. Leo replied, and then asked the squire, "Do they all know numbers?"

The attendant had worked in Joseph's Castle for many years, and of course he knew Leo and his experience, so he hurriedly said respectfully: "Master Hui, they have already learned the basic addition and subtraction with the family scholars. ”

"Well, that's good. Leo nodded and looked at Robert, "Can I cast spells here?"

Although Robert was a little strange, he quickly replied, "Yes, I have set up a magic stabilization magic array here, and there will be no problems in general." ”

Leo didn't say anything more, just spat out a few syllables, and the three quills on the laboratory not far away floated into the air, each dipped in ink, and began to write.

Philip didn't know much about magic and didn't know what it meant, the three children looked curious, apparently longing for it, and the squire grew in awe of Leo.

Only Robert, his eyes widened instantly, and he was speechless in surprise.

As a level 4 mage, multi-casting is not a difficult task for him, but it is difficult to control three objects at the same time so precisely, and it is not ordinary movement, but writing at the same time!

What a subtle mental power control this is!

For a moment, the way he looked at Leo was very different from before.

Although it is not clear what Leo's specific level is, this junior, who is much younger than himself, already has such a strong magical control, maybe he may really help his experiments! (To be continued......
