When Marin wanted to find a craftsman who was good at creating precision devices, he naturally wanted to create precision gadgets. What he wanted to create was a set of medical instruments - syringes, needles and infusion tubes.

Among them, the syringe is made of traditional glass. For skilled craftsmen, it is not too difficult to create a glass syringe. As for the infusion tube, Marin has also chosen the small intestine that has been cooked by the animal. However, a small valve that can adjust the infusion speed should be added on it. After all, the infusion speed should not be too fast or too slow. This is not too difficult for craftsmen who are skilled in making precision objects such as pocket watches.

The only difficult thing is to make the needle for the syringe. Because the needle needs to be thin enough and hollow. In addition, the needle must be guaranteed to have a certain strength so as not to bend easily...

Seeing this, all the old book fans guessed it - Marin is going to give Simon a blood transfusion...

Simon's symptoms are obviously a problem of excessive blood loss. Because of insufficient blood volume in the body, blood pressure is too low and the brain is insufficient, so he naturally falls into a coma.

Therefore, Marin plans to give Simon a blood transfusion to solve the problem of insufficient blood supply in his body.

But the problem is that Marin does not have the condensation reagent for blood type testing, so he cannot clearly test the blood type. If he makes a mistake, it will kill Simon.

Then, Marin remembered the problem of blood transfusions from his relatives...

However, Marin remembers that even brothers may have different blood types and cannot be transfusions randomly. Even fathers and sons may have different blood types. Therefore, he cannot determine who is suitable for Simon in his family.

However, Marin remembers that the blood type of the two parents can match the child. In addition, Marin also remembers that the blood type will affect a person's personality.

According to the characteristics of the Hoffman family, it seems that Marin and Albert have more temperaments like Madame Mary and like to use their brains. Adler and Simon are more like Old Hoffman and prefer to use their hands...

Therefore, Marin judged that the blood types of Simon, Adler and Old Hoffman should be in the same range, while he and Albert should be in the same range as Mrs. Mary...

However, he wasn't very sure. So, he'll try it...

...

The syringe syringe and the infusion tube with valve were quickly made, and the needle was indeed difficult to make. The craftsmen tried many materials, and at first they used sterling silver, but it turned out too soft. Then, they finally rolled the right needle with harder silver skin mixed with copper. In order to create the right needle, they failed hundreds of times...

Just so happened that Adler transported back to Emden by water and into Orich by cement, the needle was completed.

Then, Marin began to prepare for blood transfusion...

He didn't dare to use his blood to Simon. After all, he and Simon have a very different personality. So he could only find old Hoffman and Adler. But Adler was in Ireland at this time and couldn't help...

However, if he went to find Old Hoffman, Marin was afraid that the old man would beat him up. After all, his fake death indirectly cheated Simon. So, he was a little afraid of seeing the old man now...

Fortunately, Marin's troubles didn't last long before good news came - Adler heard that the North Sea Kingdom was in trouble, so he rushed to Emden with 40 knights and most of the fief's soldiers. Obviously, Adler planned to come back to help. After all, the unlucky things in the North Sea Kingdom reached Ireland, and Adler must be anxious.

When Marin heard that Adler was back, he was very happy. So he asked someone to quickly invite Adler to Orich.

Seeing Marin standing in front of her, Adler was stunned at first, then showed a happy expression. Then, he turned into anger:

"Why are there news of you dead in Europe? Don't you live well? I'll announce that you are alive so that the betrayed legion will return. Otherwise, the Beihai Kingdom will be lost!"

Marin carefully paid attention to Adler's expression, and was sure that he had not seen disappointment in his expression, so he became happy - it seemed that Adler had no ill intentions when he came back this time. Otherwise, he would definitely show a disappointed expression when he saw Marin.

Since the boss did not intend to bully Caesar, Marin naturally felt no grudges. Then, he asked Adler to keep it secret for the time being. Even, don't tell Old Hoffman and Mrs. Mary, so as not to accidentally reveal the secret.

But Adler still punched Marin angrily because he also thought that Simon's injury was related to Marin's fake death.

Although the corners of his eyes were blushed, Marin was not angry at all. Because Adler beat him up for Simon, he did bear great responsibility.

After beating Marin, he heard that he was going to draw blood. Adler rolled up his sleeves without hesitation...

...

But Marin didn't dare to be careless because even brothers may not match their blood types. Marin did not have a technical verification of accurate blood types, so he could only guess.

In order not to kill Simon, Marin hesitated for a long time and drew a small amount of blood from Adler and injected it into Simon. In this way, even if it doesn't match, Simon will not be finished.

After the first blood transfusion, Marin observed for three days and found no abnormalities before breathing a sigh of relief - it seems that the statement that blood type determines personality did not lie to me, and the blood types of muscle men and muscle men are indeed matched...

Then, he increased his blood transfusion, but still did not get a large amount. After observing for two more days, he finally got a large dose...

Then, Simon's pulse began to become stronger, and his face turned pale and rosy...

...

"Huh... I'm scared to death, I'm afraid I'll kill Simon! It seems that I still have to study serum specifically used for blood type testing! This... may be handed over to Ada?"

When it comes to medicine, Marin knows a lot, but he is always a joke. His real medical level is not as good as Da Vinci. Therefore, the burden of developing blood type reagents has to be on Da Vinci. Who said that he is not only good at medical means such as anatomy, but also knows alchemy.

No matter what method he uses, as long as he can develop one or two reagents that can coagulate a certain blood type but make other blood types unable to coagulate, it can be used for a simple blood test. It would be even better if he could simply measure blood type O, the king of blood transfusion...

As Simon's condition gradually improved, Marin's guilt finally breathed a sigh of relief...

However, Marin, who was full of conspiracy and tricks, suddenly had another plan...

"Simon, keep pretending to be unconscious! Only in this way can I have more reason to avenge you and kill those who murder you!"

Marin said it was high-sounding, but in fact, it only gave him more excuses to annex the enemy. However, this reason was enough to coax Simon, who was not interested in using his brain.

"Okay, I continue to pretend to be unconscious. But it's so troublesome to pretend to be unconscious..." Simon looked at Marin pitifully. Subtext - I want benefits!

Marin thought for a while and said:

"Don't you want to fight? After this war, I will ask you to lead troops to the wild continent to destroy an indigenous country!"

Marin was worried about letting Simon lead troops to fight in Europe alone. However, there was no problem in sending to eliminate the Aztec and Inca empires in Mexico. Simon had no brains, but the Indians were even more stupid...

When he heard that the battle to destroy the country could be fought, Simon immediately agreed to cooperate with satisfaction. Then, he began to fantasize about his dream of commanding tens of thousands of troops to slapped the enemy country.

But Simon didn't know that if he could destroy the Aztec Empire and the Inca Empire, he could push him to the right place with only a thousand soldiers. Thousands of troops? He was dreaming... But now Marin would not tell him the truth, so that he would not regret it...

...

After Simon agreed to continue pretending to be unconscious, Marin began to find spies who were proficient in makeup, making Simon's face more sick. Then, he arranged to "repair" in the planned house. Marin even specially arranged foreign envoys to visit Simon in the "unconscious".

In order to make Simon even worse, Marin not only asked the spy to put on Simon's very sick makeup, but also wrapped a blood-stained bandage on his wound. Of course, he usually doesn't wrap around, and when someone comes to visit him, he will immediately add a layer of "blood-seepage" bandage on his real bandage, which looks extremely miserable...

...

Then, Marin instructed Angela to issue a relatively young battle manifesto in the name of 10-year-old Caesar, announcing the news that his uncle Simon was "hardly injured and unconscious, and at risk" after being injured by the Eight-Nation Alliance. Then, he publicly vowed to destroy the eight countries and avenge his uncle...

After the manifesto was made public, many people sympathized with the 10-year-old Caesar and were also gloating. When the two Dukes of Henry learned about it, they laughed:

"His uncle was so beaten up by us that he was just a 10-year-old brat who could defeat our powerful coalition? Celebrate, allies, we will win!"
