Duolai was busy nearby, and soon he made half a basin of black and red liquid. He used a syringe to extract some things from it, and then took it to the side of the soldier. Looking at the terrified soldier, he said expressionlessly, "This is the crocodile dragon blood I purified. Although it has only reached the fifth level, there is no other way. I lack the main tools to derive a higher level of blood, so I can only let you suffer for now."

Dolai didn't have any living crocodile dragons on hand, so the crocodile dragon blood would be less and less as he used it. He came up with an idea, which was to let these people have crocodile dragon blood, so that he could get the relevant blood continuously and continue his experiments.

This incident seemed very evil and terrifying. In human society, it was definitely the behavior of a dark wizard. But when I thought about the fact that these people were desperate criminals and who knew how many innocent lives they had killed, the little bit of shame and uneasiness in my heart completely disappeared.

He who kills others will be killed.

Since they are not dead, they can just be the test subjects.

With Dolai's current knowledge of biology, he knows that blood transformation is divided into two parts. One part is that after the blood potion enters the body, it stimulates the bone marrow, reshapes the bone marrow, and allows the blood produced by the bone marrow to have the power of blood. In the second step, the new blood transforms the body, starting from the blood vessels, then to the internal organs, and then to every corner of the body, muscles, and membranes. In the meantime, if one link is not coordinated well, the blood experiment will fail.

With his level of potion refining, the success rate is naturally high enough, and this person is a level 5 warrior, his body should have good recovery power, so the failure rate will be reduced to the lowest, and should be infinitely close to 100%.

Thinking of this, he directly inserted the needle into the soldier's thigh.

The thigh did not react at all, not even a movement. After all the medicine was injected, Dole retracted the syringe, turned around and left.

Next to this man, there were three test subjects lying there, allowing Dole to operate them without any movement.

…

A light curtain appeared beside the man, with rays of light shooting out from it, covering the entire person. On the light curtain, lines of data began to appear.

"Bone marrow transformation is progressing slowly."

"The bone marrow transformation was successful and new blood began to be produced."

"Blood corrosion detection begins. Corrosion level is 13 percent. The recipient's blood vessels are rotting. Treatment begins."

"Blood went into the body, the body started to rot, and treatment began."

"The blood enters the five internal organs, causing them to rot, and the treatment begins."

"Blood gets to the brain, the brain is damaged, and normal healing begins."

A series of data is refreshed.

The soldier's body was shaking constantly. He was shaking violently on the experimental table. His eyeballs bulged and bloodshot spread from all sides, soon covering his entire eyeballs.

Pain, severe pain. Apart from the pain, he could hardly feel any other sensation.

Ahhhhhhh.

He screamed in his heart.

…

I don’t know how long it took, but the pain quickly subsided, the soldier rolled his eyes and fainted.

However, the body transformation is still in progress. From time to time, the body trembles, the skin turns bright red, and the blood vessels bulge and entangle, which looks very scary.

Dole left right after the injection, without worrying about failure at all. This medicine is very mature, so he felt relieved.

There were four unconscious people lying in the laboratory. Two had crocodile dragon blood, one had red dragon blood, and one had a blue dragon blood. One of them failed and was disabled.

There are three more of his current test subjects, and with these four, there are seven people in total.

Fortunately, the transformation was very successful. In a few days, he will be able to get fresh blood. Although the quality may be lower, it doesn't matter because it can still be purified.

In addition to blood tests, Dole will also conduct tests on other drugs.

After obtaining the complete versions of potions of various levels, he now has enough reserves of potions for researching many things. The sixth-level potion is no longer a chasm in front of him, but a thoroughfare.

In addition to regular potions, many unconventional potions are of great value to study. For example, the vanishing potion can simulate the wizard's invisibility spell, making a person disappear on the spot. Another example is the transparency potion, which can turn a person into the form of transparent glass. The pharmacology of this potion is worth studying.

Pharmacy is a profound and extensive subject that is well worth spending a lifetime studying.

In fact, after getting all the potions from President Puyousi, Duolai had no interest in potions below level 6. Only after reaching level 7 did he get some interesting potions.

For example, the Enlightenment Potion is a rather peculiar potion. It can instantly make a person's mental power more than a hundred times more active, instantly improve their comprehension ability, and make it easy to enter a state of enlightenment.

For example, physical fitness potions can directly improve a person's physical fitness and comprehensively improve a person's three measurements, which is quite powerful.

After reaching level eight, one corresponds to a level six wizard. The potions here are even more powerful, which makes Dolai very envious.

However, after reaching level eight, the rarity of medicinal materials increases sharply. Sometimes, even if you have the recipe, you may not be able to find the medicinal materials. This is the biggest problem.

When he came, he asked Grete to buy some level six and level seven medicinal herbs, which was already amazing. As for level eight medicinal herbs, their Orn family did not have many of them, so they had to be left to some high-level pharmacists, not to him.

Even those level six and seven medicinal herbs were only obtained because of the fact that Gretel was now in charge of the Wizard Tower. As Gretel was in charge of the Wizard Tower, she could obtain a huge amount of merits. By exchanging merits for medicinal herbs, the Orn family would not lose out.

The older generation of the Orne family are very calculating.

Three days passed quickly and slowly. Dolai's fourth experimental subject's body gradually stabilized and his breath increased significantly.

At this time, the weather outside finally cleared up, the wind disappeared, and the long-lost blue sky appeared.

The sky over the Arctic ice field is very blue, revealing a deep blue color. Looking out at the sky, there is a deep black color, as if brewing in the blue.

Dolai stood on the wizard tower and looked at the ice field.

It is boundless and very flat here. There is a layer of ice on the ground that is who knows how many meters thick. The air is very clear. At a glance, you can see hundreds of kilometers away, but you still can't see any edges.

I looked up and saw a hint of starlight even in broad daylight. I then looked at the sun, which had just risen and was only a little above the horizon.

After seeing the starlight, Dolai and Ash each sighed. They were indeed flying towards the innermost part instead of flying along the edge of the ice field, and now they had to go back.

Dolai took a close look at the sky, felt the weather around him, and thought for a moment, "I can feel that the weather will be sunny for a few days. Let's hurry and get to the beach first."
