Colonel Roy walked into the room with a middle-aged man whose temples were gray and looked a little old.

"Thank you Colonel for your concern, I'm much better now, and I'll be fine while sitting." Lin Xuan said with a smile.

"Let me introduce you, this is Dr. Marco, who we finally invited back, is a national alchemist, titled 'Crystallized Alchemist', who has been engaged in research on the application of alchemy to medical treatment in the central government."

"Don't exalt me, I don't deserve the title of national alchemist at all." Doctor Marco smiled bitterly and walked in front of Lin Xuan.

"Let me see your ......"

Because Lin Xuan was injured too much, he was thickly wrapped in a layer of gauze, and he looked a little like a mummy.

"It's unbelievable that they've all scabbed!" After seeing Lin Xuan's wound that had begun to heal and scab, Dr. Marco let out a sigh and immediately drew a refining array on the ground.

Looking at the refining array that was gradually taking shape, Lin Xuan was a little strange and asked, "Can such a simple refining formation really be used for treatment?" ”

In the library before, Lin Xuan also had a certain amount of research on the refining array, and knew that the more complex the refining array, the more powerful the effect, but the refining formation portrayed by Doctor Marco was very simple.

"Oh? You're also an alchemist? Seeing Lin Xuan ask like this, Dr. Marco looked at Lin Xuan in some surprise.

"No, I'm not an alchemist, I've just read some materials, and I wanted to learn alchemy with Colonel Roy." Lin Xuan shook his head, glanced at Roy, and said with a wry smile.

On this trip to the Fifth Research Institute, he earned a total of 1,000 Fame, but he was still 900 points short of collecting 3,000 Fame.

"You're not an alchemist, it's normal not to know...... "When an alchemist understands that technique thoroughly, he can simplify the refining array, and I used to treat the people of the town when I was in seclusion, and this technique is too familiar to me." ”

"Alright, let's stand on the refining array." After drawing the refining array, Doctor Marco said to Lin Xuan.

After Lin Xuan stood firm, Mark pressed his two hands on the refining array and began refining.

The green refining light lit up, and Lin Xuan felt a warmth enveloping his body, and an itching sensation gradually came from the wound, and the wound was healing at a speed visible to the naked eye.

At the same time, Dr. Mark was oozing sweat from his forehead, which showed that this was not easy for him.

It wasn't until the deepest wound on Lin Xuan's arm healed that Doctor Marco also stopped refining, wiped the sweat from his forehead, and said, "You suffered some skin injuries, and now you are fine, but it is best to recuperate for a while, it will not be harmful to your body." ”

Lin Xuan touched his arm and found that there was no trace of scarring, and he had to sigh once again at the magic of alchemy.

"Coo-......" At this moment, Lin Xuan's stomach rang out uncontrollably, and an unprecedented feeling of hunger surged into his heart.

"By the way, I forgot to tell you that due to the principle of equivalent exchange in alchemy, healing your body will consume a lot of energy in your body." Dr. Marco said.

Looking at Lin Xuan's embarrassed expression, Xiaolan couldn't help but laugh out loud.

"It's just noon, let's go eat first." Colonel Roy also smiled slightly and said.

After eliminating a few large bowls of rice, Lin Xuan finally patted his stomach with satisfaction. The extreme hunger he had felt before was really uncomfortable, and he didn't want to experience it again.

After eating, everyone including the Edward brothers was called into Roy's office.

After the bear walked into the office, he saw that Lin Xuan was also coming up, asking about his injuries, and it seemed that he had not alienated Lin Xuan because of the previous incident.

"Ahem......" Colonel Roy coughed as he sat down, and the office fell silent.

"What happened to the Fifth Research Institute is of a very bad nature, and I hope you will tell you what you know. Steel, you say first. Roy looked at Edward and said.

Edward, who was still a child, also stood up straight after seeing Roy's serious expression, and said: "After meeting Dr. Marco earlier, after he told me the clues about the Philosopher's Stone, I found the first branch of the Central Library, but when I arrived there, I found that the materials in the library were burned to the ground. ”

"Wait......" Lin Xuan suddenly interrupted Edward's words and asked, "The Philosopher's Stone... Does it really exist? ”

He wanted to ask in the Fifth Research Institute before, but due to the situation at the time, he couldn't ask.

Among the materials about alchemy that Lin Xuan had read before, there was a clear record: "The stone with a bright red color like a pomegranate contains a huge amount of energy, and the alchemist can complete the technique without using the alchemy array, and without any price, it is the legendary gold stone." "But no one knows if the Philosopher's Stone exists.

"The Philosopher's Stone does exist." Roy nodded and said to Lin Xuan, "The reason why Dr. Marco is called the Alchemist of Crystals is because he once refined the Philosopher's Stone. ”

"Really, why didn't the Colonel tell us if he knew that Dr. Marco could refine the Philosopher's Stone? We've been looking around for a long time. Hearing Roy say this, Edward said with some dissatisfaction that the two brothers had traveled many places in search of the Philosopher's Stone.

"Dr. Marco was missing at the time, so it's useless to tell you......" Roy smiled wryly.

Hearing that Dr. Marco was able to refine the Sage's Stone, Lin Xuan also showed a surprised expression.

However, Dr. Marco covered his head in pain, as if he didn't want to think about the past, and said, "It's just that I was blinded by fame at that time, which caused the misery of life at that time......

Through Dr. Mark's mouth, Lin Xuan learned that the Philosopher's Stone was actually made of living people, and at that time, the military department put the refined Philosopher's Stone into the war, resulting in a one-sided situation at that time, and countless lives were completely lost because of the Philosopher's Stone.

"After the battle of Ishvar's annihilation, after seeing the terrible situation on the battlefield, I felt deeply shocked and regretful, my sins, even if I die, I will not be able to pay for them." Doctor Marco said slowly, and Lin Xuan found that Colonel Roy's face was also a little unsightly, thinking that he should have participated in that war at that time.

"But even so, I wanted to atone for my sins, so I quit the military department and went incognito to become a doctor in a small town."

Speaking of this, Dr. Marco smiled bitterly and said, "But it's really providential, I have been incognito for many years, and I was still met by Edward." ”

"Alright, Steel, you can go on." After Dr. Marco finished speaking, Colonel Roy brought the topic back again.

Under Edward's explanation, Lin Xuan and the others also understood the general idea of the whole thing. The Edward brothers infiltrated the Fifth Research Institute because of the two dead reincarnators. It's clear that they know the plot of this world and know it well.

It's just that what they didn't expect was that in the Fifth Research Institute, in addition to No. 48 and No. 66, there was actually a reincarnation hidden behind them, which led to the tragedy that happened next.

This also made Lin Xuan and the others sigh, they were not facing the enemy in their heyday, otherwise they would probably end up the same as Jiang Ze and the others.

"What about you? Why did you go to the Fifth Research Institute, and who are those two? After Edward finished speaking, Colonel Roy moved his gaze to Lin Xuan again and asked.

Seeing that he asked himself, Lin Xuan took out the words he had thought of in advance, and said, "At that time, I got a copy of the architectural drawing of the Fifth Research Institute from the enemy, and since then I have been a little strange, why does the other party have this drawing. ”

"Just when I suspected that the enemy might have some conspiracy, Major Hughes told me that Jiang Ze and the two disappeared near the Second Prison, and I felt that something was wrong, so I sneaked into the Fifth Research Institute."

Lin Xuan talked eloquently, his words were full of righteousness, as if they had infiltrated the Fifth Research Institute for the safety of the country, and even Xiaolan and the two of them almost couldn't listen to it.

However, when talking about Enwei and Rust, Lin Xuan didn't know what the other party was, the only thing he knew was that the other party belonged to the android camp, so he couldn't say this.

"I don't know who they are, but they all have one thing in common, that is, they can't be killed." Lin Xuan said with a solemn face, the other party did leave a great shock on him at that time. Although I have seen such similar abilities in movies, it is another thing to see them with my own eyes.

"In addition to the damage done to them, they all seem to have a Ouroboros tattoo on their bodies...... "With his observational powers, he can see that Envi has the same tattoo on his thigh and on the front of Rust's neck, which he can't be mistaken.

"Hmm......" After hearing Lin Xuan's description, Colonel Roy's brows furrowed slightly, obviously without the slightest clue.

"By the way, before we infiltrated the Fifth Research Institute, we were followed by the military, as if the president ordered them." Suddenly, Lin Xuan seemed to think of something and said.

As soon as these words came out, Roy suddenly slapped the table, stood up suddenly, and said, "What!? Are you saying that this matter may still have something to do with the president? ”
