Chapter 652: Improve the Four-Ring Necromancy Magic and Help Brother Lin Advance!

Gretel's lecture on the frog experiment, wrong, on central and peripheral nerves, and conjectures on nerve electrical signals, was a great success in Black Crow Swamp. After the lecture, the necromancers swarmed him and almost blocked him from entering:

"So the principle of the level 1 spell [Terror Spell] is to use spells to simulate electrical signals and conduct them to the nerves of the target?"

"Uh...I don't know about this...but I can provide a test method. You use a silver cage, the denser the better, to cover the whole body of the caster. Try to see if it can weaken the effect of the spell...If you don't have enough money, cover it Maybe the head can also..."

"So my suture monster always refuses to obey my orders. Is it because I injured my nerves while suturing?"

"Uh... I really don't know if the nerves in the corpse are still active. Maybe you should do an experiment to test it?"

"So, can adding nerve lines made of silver wire to the skeleton soldiers improve their control performance?"

"...Why the empty skeleton can move, I really don't know this!!!"

I have never made an undead creature myself!

I don't know how to order, scold, or turn away undead creatures!

I'm really not a necromancer! ! !

Fortunately, Archmage Edgar escorted him, and Gretel was able to leave the Sleepless Tower with all his beard and tail, and fled. After escaping back to his mage tower, Lin En heard that he was giving a lecture today and felt very regretful:

"Hey, why didn't you call me? I'm currently studying level 4 necromancy in preparation for advancement, and I want to hear more about it!"

"Well, I was temporarily pulled to give a lecture..." Grete shook off his sweat and said, "Then shall I give the lecture again?"

"No need...you have to write a paper anyway, I'll just take a look at it then."

"Okay... okay..." Gretel didn't force him, and was determined to write the paper in more detail. He added an outline of the paper in his mind and stretched his head out of curiosity:

"Brother Lin En, are you already preparing for the advancement? Which spell do you plan to use to advance? Manipulate the dead? Disease? Or fear?"

When he mentioned an option, Linn shook his head. Grete told him all the spells he could think of, and then he saw the golden skeleton next to Linn, shaking his head like a rattle, and fell down with a "snap":

"Click, click, click, click... Gulululu..."

In one breath, he rolled to the soles of Gretel's feet, spun around, and lay still on his shoes.

Gretel: "..."

"What you said has no meaning in improving my ability." Lin En smiled:

"Manipulating dead corpses, I already have a few skeletons to use, so I'm not in a hurry to learn it; the disease technique, since you revealed the transmission route of infectious diseases, it doesn't feel too difficult; the fear technique is nothing more than a level 1 panic technique. Scope.”

His eyes shone with confidence, and he seemed to have mastered advancement. He just wanted to pursue the best growth before choosing the most challenging research topic:

"I chose [Blood Burning Technique]. This spell has never been used in a similar way before, so it's worth spending more energy on it."

Oh... the blood-burning technique... Gretel quickly recalled it. Thanks to Archmage Carlisle, although he could not learn the fourth-level spells yet, he had memorized the names and introductions:

Burning Blood, a fourth-level necromantic spell. Inject a hot, corrosive substance into the blood of a living creature, causing the living creature to be harmed by both fire and strong acid.

The casting method is non-contact casting, the distance is 100 feet + 10 feet per level, and the casting material is 1 drop of blood + 1 saltpeter.

Burning Blood cannot affect constructs, elemental creatures, earth creatures, plants, and undead creatures. Simply put, it cannot affect anything without blood.

It sounded like saltpeter was dissolved in blood, and then a spell was forced into the blood vessels of the target, and then ignited... Gretel shivered and still asked with concern:

"Was the study successful? What were the problems?"

"There are quite a few problems." Linn frowned slightly. He was usually reluctant to trouble others, except Gretel. This guy often has fantastic ideas. Chatting with him can open up ideas and solve problems from another direction:

“First, the caster’s resistance will be relatively strong, and saltpeter will not be easily injected;

Second, it is easy to miss the mark. Even if it hits the torso or arm, the spell may fail;

Third, after injection, it is easy to fail to cause fire and strong acid damage. Sometimes there is only one, and sometimes none of them can cause..."

Gretel frowned after him. As for the resistance of the target, he couldn't understand why remote casting could inject a substance into the opponent's blood vessels. But he did have some ideas for the next two questions:

"Brother Linn, let's do it one by one. To solve the problem of failure of fire and strong acid damage, I remember that saltpeter can be ignited and can also be retorted to make nitric acid. So, should we change to other casting materials, such as nitroglycerin? "

emmm…

Linn thought carefully. Then, he asked Grete for a small bottle of nitroglycerin and went straight to the experimental area downstairs. Point at a rabbit, chant silently, and raise your finger——

"The spell resistance is much smaller, almost zero - but the damage is wrong!"

No fire damage, no acid damage. The rabbit fell silently.

Gretel flew forward. He felt the carotid artery, then picked up the rabbit's eyelids and looked at it. Based on his experience, the rabbit should still be alive, but it seems to have low blood pressure...

Also, a small grain of saltpeter can cause powerful fire and strong acid damage in the body of the target; if a small drop of nitroglycerin is poured in, won't the blood pressure drop to the bottom?

Gretel thought nervously for a moment, then took a shot of [Inspiration Technique]. Plop, plop, plop, a large amount of adrenaline is secreted, myocardial contractility is strengthened, heart rate is accelerated, cardiac output is increased, mucosal vasoconstriction, blood pressure increases...

After a while, the rabbit's chest rose and fell, and its front legs barely moved.

"Grete, why did the resistance of [Blood Burning Technique] decrease so much and the damage change when the casting material was changed to nitroglycerine?"

"Probably because nitroglycerin is a medicine, it may be beneficial... As for the damage being greatly reduced, maybe it didn't ignite?"

Grete is sad. This magic can be modified and it seems that it can become a powerful clinical rescue spell: for example, give some adrenaline, some dopamine, some lidocaine, etc.

It can skip blood circulation and go directly to the inside of the human body without invasive operations...

However, it is too difficult to control the magnification of this medicine! Looking at the way the rabbit fell, it was as if he had drank a large glass of nitroglycerine rather than just a drop of it!

Can I use 1 ml of casting material and the effective dose is only 1 ml?

"Forget it, let's look at the second question. It's easy to miss the mark and the spell fails... Is it because you can't identify the blood vessels?"
