Drink Black Tea Calmly at Hogwarts

Since December, students at Hogwarts have recently noticed some new changes in the classroom. ＷＷＷ.SUIMENG.lā

During the Potions class, Professor Snape's lectures were much more detailed than before, and his mouth was not so venomous.

If it weren't for the fact that his hair had always been unwashed and greasy, the students would have suspected that Professor Snape was fake.

In other classes, Hagrid would sometimes be seen sitting in the last row of the classroom, recording something in a notebook from time to time.

"Because Professor Dumbledore has talked to them."

Professor Zhang said this when discussing this topic with his classmates in the common room.

It was almost Christmas break, and a group of students quickly turned the conversation to the upcoming holiday.

Zhang Xu had already asked someone to help him book a plane ticket to return home. He was going to leave as soon as the holidays came. Even if Voldemort led the Death Eaters to attack Hogwarts, he would not be able to stop him.

"You have new text messages, please check them carefully!"×N

Zhang Xu, who was sleeping soundly, was awakened by a ringing sound.

I got up in confusion and found that the communicator used by the professor was ringing.

When someone woke me up in the middle of the night, it was definitely not someone bringing red wine to look at the moon.

Zhang Xu took the communicator and found that it was a text message from Dumbledore, telling him to rush to the principal's office immediately.

Suddenly remembering what was going on, Zhang Xu immediately put on his robe, wetted a towel with his wand, wiped his face and ran out of the dormitory.

Arriving at the door of the principal's office, Zhang Xu saw Professor McGonagall walking anxiously with a group of red heads, and Percy was also inside.

Behind this group of red heads, Scarlet came along.

Entering the office, Dumbledore immediately said to Zhang Xu: "Zhang, Arthur is seriously injured. The news from St. Mungo's is not optimistic. I need your help."

After Zhang Xu nodded immediately, Dumbledore continued: "Heraison, please take Zhang to St. Mungo's. I will ask Dai Lisi to notify the therapist at St. Mungo's to cooperate with you.

"

Hearing that the situation was urgent, Zhang Xu and Scarlet said nothing, said "Okay" and turned around to leave.

After the two quickly walked out of Hogwarts, Scarlet grabbed Zhang Xu's hand, and then used Apparition to take him to St. Mungo's Hospital for Magical Injuries and Injuries.

Dumbledore knew that Zhang Xu had a trump card in detoxifying, so he learned from Harry that Arthur Weasley had been bitten by a snake, and then learned about Arthur Weasley from the portrait of Delis de Winter. The wound was very difficult, so he asked Zhang Xu to help.

Zhang Xu had just remembered that Mr. Weasley was bitten by Voldemort's snake tonight, so he agreed to Dumbledore's request without saying a word.

Arriving at St. Mungo's Hospital for Magical Injuries and Injuries, Zhang Xu and Scarlet were led by the therapist waiting for them in the lobby to the medical room where Mr. Weasley was being treated.

Zhang Xu walked into the medical room, while Scarlet was waiting outside.

Mr. Weasley was lying on the hospital bed with his shirt off. His face was sickly pale from blood loss.

Several healers were using various methods to stop the bleeding from the wound in Mr. Weasley's side.

A bucket next to the hospital bed was almost full of gauze stained red with blood.

Seeing Zhang Xu come in, a man who looked like the attending therapist came over.

Although the reinforcements sent by Dumbledore were too young, the healer did not underestimate them.

After all, Lao Deng's signature is there, and they trust Lao Deng more than themselves on technical issues.

There was no plot like questioning → arguing → being slapped in the face → bowing down → the patient died because the rescue time was delayed. The therapist immediately introduced Mr. Weasley’s condition to Zhang Xu.

"Judging from the wound, the patient was bitten by a huge snake. His ribs were bitten off. The wound was poisoned and the bleeding could not be stopped even after using various methods." The therapist frowned and said, "Currently, the patient has lost too much blood. The situation is very dangerous. The patient's body is very weak, and the blood tonic medicine he drank is difficult to work."

"I will deal with the toxins." Zhang Xu said, "You can try to use local freezing to stop the bleeding."

"If possible, I recommend giving the patient a blood transfusion to prevent the patient from dying from excessive blood loss."

"Muggle method?" asked the Healer. "Would you use this method? I think we can try it."

"I don't know how, but I can find someone who can." Zhang Xu said, "That person is a parent of a Hogwarts student."

Zhang Xu remembered hearing Hermione say that her father was a dentist and her mother was a physician. They had never eaten pork or seen pigs running.

Mr. and Mrs. Granger have a good relationship with Mr. and Mrs. Weasley, and I believe they will help.

And since they are the parents of wizards, they don’t have to worry about their memories being erased by people from the Ministry of Magic.

Zhang Xu took out a black box wrapped in thick rubber. This is a magic-proof box that can ensure that the electronic products inside will not be damaged by magic interference.

Zhang Xu handed the box and phone book to Scarlet and asked her to contact the Grangers immediately after leaving St. Mungo's Hospital and ask them to come over for help.

The therapists began to use local freezing method to stop Mr. Weasley's bleeding according to Zhang Xu's suggestion. Zhang Xu had only seen the name of this method on the Internet in his previous life, but he didn't know the specific operation.

But this is a magical world, and there shouldn't be a situation where the patient dies even though the bleeding is successfully stopped.

And this seems to be more reliable than the ignited bullet flame inside to stop bleeding.

Zhang Xu walked to the other side of Mr. Weasley's wound, took out a first aid kit and put it on the shelf nearby. After opening the first aid kit, he took out a small syringe sealed in a plastic bag.

Then he took out another ampoule, cut the mouth of the bottle, sucked 0.1ml of antivenom into the syringe, and then added 1.9ml of physiological sodium chloride injection to mix it into an injection.

Relying on the skills he had practiced giving Wangcai injections at home, Zhang Xu injected 0.1ml of medicine intradermally into the palm of Mr. Weasley's forearm.

After the injection, Zhang Xu remembered that he had forgotten to disinfect Mr. Weasley's arm with alcohol.

Anyway, in this magical world, it should be fine without disinfection. Zhang Xu thought.

After giving Mr. Weasley a skin test with antivenom produced at home using basilisk venom, Zhang Xu took out a test strip for rapid blood detection from the first aid kit. This test strip can detect the bleeding type within one minute [Note] .

Zhang Xu breathed a sigh of relief when he saw Mr. Weasley's blood type. Because Zhang Xu himself also has a blood type, he can be given blood transfusions when necessary.

At this time, the healers had temporarily frozen Mr. Weasley's wound and the bleeding had been stopped.

Next, Zhang Xu tested the blood type of a therapist who was willing to donate blood, waited for the skin test reaction of the antivenom, and waited for reinforcements.
