On the way back, because the airship had become a 'ship', and the corpse of the giant beast had to be dragged away, several people had to drift on the sea for three whole days......

Due to the dispute that broke out before, along the way, everyone raised their vigilance to the extreme, and they didn't even dare to close their eyes when they slept.

In this atmosphere of mutual jealousy, Lynn did not deliberately provoke disputes, after all, this 'ship' was too small, and once a fight broke out on it, it was very likely to damage the cabin or the compass in North's hand, and he would have to drift on the misty sea forever......

North, Hank, and Barbara obviously understand this, so even though the atmosphere is a little tense along the way, they still maintain a harmonious posture on the surface.

It wasn't until the evening of the fourth day that the 'ship' took advantage of the darkness to return to the land of wizards.

"It's finally back."

Stepping on land, Barbara slowly breathed a sigh of relief, feeling that her legs were trembling, the sea of mist was too torturous, there was nothing but white fog, and Hank even scolded that he didn't want to cross the sea by boat again in his life.

"Anyway, everyone has worked hard this time, and I promise you something, and I will give it one by one in a few days." North said tiredly.

"You'd better not delay too long...... Barbara reminded her that the money she paid for the high-grade magic crystal cannon was not a small amount of money she had paid for herself.

North just nodded in agreement, and then ordered his men to arrange a few carriages to send a few people back to the city overnight.

Lynn didn't mean to delay when he returned to the estate in Ladakh.

After returning to the castle in Ladakh, he asked Coleman and others to catch a hundred rodents for him to use as biological experiments.

With such an order, Coleman was directly dumbfounded, where did he catch so many rodents?

In the end, the apprentices who were doing the experiments had to stop what they were doing, catch mice in the castle, and work for half a night to barely make up half of them, so they had to go to other places to catch them.

Lynn quickly realized the convenience of having a power, whether it was potion materials or rodents for experiments, all of them were available to him in a matter of hours......

Taking advantage of this time, Lynn reviewed all the books in the Chamber of Secrets on the making of the Source of Magical Power, and then took out the crystal that had been taken out of the Eye of Death's brain.

The appearance of the crystal looks translucent, showing a dark red hue, and the surface is covered with strange runes and patterns, which makes people fall silent at a glance, as if the soul is about to be absorbed into it.

Judging from the weighing, it is only about 150 grams, which is very light, and according to Ladakh's notes, it usually takes 30 grams of spiritual essence to boil a serving of [Source of Magical Power] as a material.

In other words, these spiritual qualities are only enough to make five copies of [Source of Magical Power] at most, which seems to be a lot, but if it is used for experiments, I am afraid that it will not be enough at all.

Lynn could only save as much as possible, and placed the same amount of salamander, griffin, and death's eye spirit into the potion that had been boiled a long time ago, and made three bottles of [Source of Magical Power] of different colors.

Then, in units of 0.5 milliliters, nine rodents were arranged as the target of the experiment, each in a group of three, and each of them was asked to take the corresponding potion.

Probably because there are too few, after waiting for a long time, it doesn't have any effect at all.

According to Ladakh's notes, this thing should take effect in a matter of seconds!

Lynn was only able to slowly increase the dosage until the total amount of the dose exceeded two milliliters, and three of the rodents immediately began to move, and began to become more and more irritable, and one of them even tried to bite through the cage......

These rodents had just taken a potion made from the Spirit of the Eye of Death.

Lynn recorded all of these changes, and then grouped the control groups into groups.

Of the three rodents in each group, one dissected the recorded data on the spot, one remained as it was, and the other continued to increase the dose for the experiment......

A hundred rodents may sound like a lot, but in fact they are not enough in the case of controlled experiments, and in just one night, the materials at hand are almost used.

The wide bench was littered with dead rodents of all shapes, some of which he had dissected, and some of which had died of an overdose of potions.

The rodent who had taken the Eye of Death potion was the most terrifying, after drinking about five milliliters of the potion, his eyes began to turn red, his mouth screamed differently, and then died without warning after half a minute.

What frightened Lynn the most was that he even had the feeling of facing the eyes of death when he was looked at by those red pupils.

However, he killed all the main body, and Lynn was not afraid of a small rodent, grabbed the last test subject, forced it to take five milliliters of potion, and then directly performed live dissection without waiting for it to die.

"Is there a strong magical response in the brain?" Lynn discovered this unexpectedly.

In fact, as long as rodents take potions, there are some magical reactions in the brain, which is normal, and it is also a characteristic of magical creatures, indicating that the formula is correct.

It's just that this rodent is a little different, the magic reaction in the brain is too strong, and it has even reached the level of a ring of magic, which can only be described as an exaggeration, and then the symptoms of brain death appeared.

Lynn took Ladakh's notes and looked at them, only to find some records of brain death caused by taking potions, and there was no mention of the reason why the rodents were red in their eyes and showed extreme aggression.

This may be a peculiarity of the Eye of Death's spiritual nature.

As a potions master, Lakda has a deep understanding of the source of mana.

Of course, this guy is not as humane as him, he directly uses human beings as experiments, and many of the missing poor people in Nancheng are related to this magic workshop, and even Rakda has done experiments with wizard apprentices, accumulating a lot of "experience".

What Lynn is doing is to confirm whether Rakda is playing any tricks in his notes, and the strength of the Eye of Death's spiritual essence, judging from the previous state of rodents taking potions, the difference is probably more than ten times.

Such a strong medicinal effect made Lynn a little worried.

Thirty grams of spiritual essence is the best ratio summed up by the Council's potions masters, which can maximize the effect of [Source of Mana], but too powerful effects may cause some side effects.

After thinking about it for a long time, Lynn finally decided to create a weakened version of the [Source of Magical Power] and find someone to try it......

If there are no side effects, take the potion yourself......
