On March 26, 1173, at 9 o'clock in the morning, Yan Tielong was teaching the first pharmacy class in the first Holy Pattern Potion Warehouse, and in order to take care of the learning progress of the two young students, the two young students were Hami Eddie and Ingrid Jade, Yan Tielong started from the basics of identifying medicinal materials, of course, a certain student couldn't stand the content that Yan Tielong said was too low-level, so he left the class directly.

Regarding someone's departure, Yan Tielong told the remaining two Tianyu students that anyone who felt that his content was too low-level could leave early like someone.

And Peggy Ishel and Aiden Esqin heard Yan Tielong's dissatisfied tone with someone, they glanced at each other, and then they both listened very seriously.

Of course, Yan Tielong taught from the basis of portable medicine, and that was a last resort, after all, it was his first time teaching, and the three Tianyu students had different levels of medicine, and he promised Ingrid Jade yesterday not to snub her, so he proposed to let her learn pharmacy with him, Ingrid Jade agreed without thinking about it, and in addition to the fact that Hami Elliyi's mother had not returned, in order to let the two little pharmacy apprentices also learn knowledge, he started directly from the basics.

It's just that Yan Tielong didn't think that Hami Elli was not weak in the foundation of the potion, which caused Ingrid Jade to suspect that she was stupid, after all, Yan Tielong asked a question, and Ingrid Siyu couldn't even answer a question.

There may be Hami Elli, and Ingrid Isyu is very enthusiastic about learning.

The time soon came to 11 o'clock, Yan Tielong officially announced the official end of today's two classes, and then assigned fifty bottles of primary healing potion production homework for the two Tianyu Academy students, and for Inglisa Jade and Hami Elliyi, the homework was to carefully review the medicinal materials they knew today, and they would check it tomorrow, and if they made a mistake, they would write fifty articles on the names of the wrong medicinal materials.

Just as Yan Tielong and his students were returning to the hotel to prepare for lunch, Kiremis at the hotel counter stopped Yan Tielong and told Yan Tielong that because the black demon was seriously injured, he asked him to go to the Governor's Mansion to treat Rossion.

When Yan Tielong heard what Kilymis said, he asked Kilymis to take care of Hami Ariy and Ingliss Jade for lunch, while he took Peggy Ishel and Aiden Isqin to the Doge's Palace.

When Yan Tielong arrived at the Governor's Palace, Yanli Maen told Yan Tielong that his senior brother Xiqi Kane was already treating their Governor's Palace.

Originally, the Flame Lion Knight soldiers took their Governor back to Guyu Town, and they looked for Yan Tielong as soon as possible, but unfortunately they didn't find Yan Tielong when they went to the Rourou Inn, so they could only find Hiki Kane to treat the Governor, and Kilymis didn't know that Bu Rosain had already found Hiki Kane, so she told Yan Tielong to go to the Governor's Palace.

After learning that the governor was being treated by his senior brother, Yan Tielong was not bothered, so he asked Yan Li Maen if there were any other members who were injured and he could be treated for free.

When Yan Li Ma En heard Yan Tielong's words, he was very moved and took Yan Tielong and them to the other injured rooms.

According to Yanli Maen, the nearly thirty or so seriously injured members of this room were all caused by black demons, it turned out that Yan Tielong asked Xiaoyin to keep an eye on the black demon until the morning, and then told Bu Luo Sain the position of the black demon, and Bu Luo Sein asked Yan Li Ma En to order the townspeople and adventurers to dig the Cao River and surround Gu Yu Town to prevent the black demon from attacking.

And Bu Rosain himself led three hundred brothers to try the strength of the black demon, if the strength was not as terrifying as in the rumor, he would directly lead people to solve it.

At first, Rosain knew that the power of the black demon was very terrifying, so he used the advantage of speed to find an opportunity to slash the huge wound on the right side of the black demon's neck, and the black demon fell to the ground because of the difficulty of breathing.

When the people saw the black demon fall to the ground, they thought that the black demon was not far from death, so they all cheered, and felt that the black demon was not terrible at all.

It's just that everyone present didn't expect that the black demon who fell to the ground actually recovered the wound at a speed visible to the naked eye, just as everyone present cheered, everyone thought that the black demon who was about to die stood up and launched a charge to crash into the people of the Flame Lion Knights.

As a result, Bu Rosain was knocked away by the black demon, but Bu Rosain's full force blow also gave everyone in the Flame Lion Knights a chance to react.

In order to save their governor, the Flame Lion knights rescued Burosain at the cost of seriously injuring more than 30 people and lightly injuring nearly 200 people.

As for the specific situation that Yan Tielong wanted to ask about the battle, Yanli Maen only knew so much, and if he wanted to know more details, he could only ask the members of the crusade team, after all, he did not participate in the crusade team.

Qiang Ran Yan Tielong was very inquired about the specific situation of Bu Rosain and their battle with the black demon, but if the more than thirty soldiers of the Flame Lion Knight Order were not treated as soon as possible, they were likely to die, so Yan Tielong patiently led two of his students to start treating the soldiers of the Flame Lion Knight Order.

After Yan Tielong first commanded and taught Peggy Ishel and Aiden Isqin to stabilize the serious injuries and delay time, Yan Tielong, who could not stabilize the injuries, began to treat, and when Yan Tielong treated the fifth person, he felt that there was a serious shortage of manpower, after all, it was too difficult for the three of them to treat more than 30 seriously injured people.

However, when Yan Tielong began to treat the sixth person, Xiqi Kane led his disciples to join the treatment team, and Xiqi Kane's treatment speed was much faster than Yan Tielong's, after all, the injured people on the scene were all internal injuries caused by the impact, and Yan Tielong was better at external injury treatment.

Seeing the arrival of Hitch Kane, Peggy Ichor and Aiden Iszin were very excited, after all, Hitch Kane was already known to be one of the disciples of the Potion Master of Platinum Wingkins.

After learning that Peggy Ishel and Aiden Isqin were Yan Tielong's disciples, Hitch Kane treated his disciples like any treatment of internal injuries and medicines, and even paid attention to treating the injured on the sidelines, in fact, Yan Tielong, who was eavesdropping, also benefited a lot.

It was already seven o'clock in the evening after the treatment of more than 30 seriously injured people, and Yan Tielong, who had finished washing his hands, asked himself Xiqi Kane: "Senior brother, Uncle Bu Rosain, what is the situation?"

Xiqi Kane Yan Tielong, who was washing his hands, asked, and said: "The governor's internal injuries are very serious, and he will need at least half a year to recuperate, and ~."

Hitch Kane said and looked around, and when he found that it was only him and Yan Tielong in the washing room, he took out a glass bottle, and the black and red liquid in the bottle.

When Yan Tielong was holding the bottle and was puzzled, Xiqi Kane continued: "The blood in this bottle was taken off the clothes on Bu Rosain's body, and the skin stained with black and red blood on the Governor's body has eczema, I have just wiped the light purification potion, and found that the two have reacted, this black and red blood stain is ominous blood!"

Hearing what Xiqi Kane said, Yan Tielong frowned, he knew that the blood in the glass bottle was the black demon.

Seeing Yan Tielong frowning, Xiqi Kane asked, "Tielong is like this?"

"Not good!" Yan Tielong shouted and looked for Yanli Maen.

When Xiqi Kane saw Yan Tielong's movements, he thought that the wounded that Yan Tielong had treated before were in the same condition as the governor, and now he went back to deal with them.

However, Hitch Kane was wrong, for the black blood stains on the seriously injured people's bodies, Yan Tielong had already purified them with water purification potion, and he was now worried that those soldiers of the Flame Lion Knights who participated in the crusade against the black demons were stained with black and red blood, so he now asked Yanli Maen to find out the soldiers and mounts who participated in the crusade against the black demons, and looked to see if those soldiers and mounts were also stained with black and red blood.

When Yanli Maen heard that Yan Tielong had a bad effect on contaminating the blood of the black demon, he sent someone to summon the soldiers who participated in the crusade against the black demon, and the situation of the war horse Yanli Maen sent someone to take Yan Tielong to check.

When Yan Tielong brought his two apprentices to the manger, they found that the manger took care of the horses and the groom was actually attacked by the horse, you must know that the groom is very familiar with the character of the horse, and it stands to reason that the horse will not attack the groom, after all, the groom is the parent of food and clothing in the eyes of the horse.

Yan Tielong used his dragon power to suppress the rampaging horses, and then checked the rampaging horses, and found that those rampaging horses were indeed stained with the blood of the black demon.

Yan Tielong distributed water purification potions to his apprentices and grooms to treat horses stained with black demon blood, and as a result, one hundred and fifty-eight horses were treated, causing Yan Tielong to use up all the water and light purification potions.

So Yan Tielong asked Yanli Maen to send someone to find Xiqi Kane, and after learning that Yan Tielong was looking for him to treat the soldiers who participated in the crusade, he took out a large amount of water and light purification potion, and the purification potion of other systems had little effect on the blood stains of the black demon.

It's a pity that the more than 300 soldiers who participated in the crusade were more or less contaminated with the blood of the black demons, and as a result, the Xiqi Kane potion was not enough, so Yanli Marn sent soldiers to urgently buy water and light purification potions, and then Yan Tielong and Xiqi Kane taught them to make water and light purification potions in front of their apprentices on the spot.

Peggy Ishel and Aiden Isqin were very glad that they could learn the water and light purification potion, and if they left early like Phoebe Berg, they would definitely not be able to learn the water and light purification potion formula.

After Yan Tielong and Xiqi Kane had finished making one hundred and twenty water and light purification potions, it was already ten o'clock in the evening, and after having dinner, they returned to the Rourou Inn.

And Yan Tielong returned to the inn, he didn't sleep, but used the identification technique to identify the black demon blood that he got from Senior Brother Xiqi Kane, he wanted to see what effect the black demon blood would have.

As a result, after five identification techniques, Yan Tielong discovered that the blood of the black demon actually had a high concentration of devil's blood, which made Yan Tielong think about the extermination of the Anyusi cult not long ago, and he suspected that the black demon might have been transformed by the Anyusi cult, and at the same time, the identification technique also showed that ordinary water could be used to treat the symptoms of being infected by the blood of the black demon.
