"Ahh......h So, what are you doing when you're back so soon? ”

Back on the second floor of the Alchemy Guild, the corpse had been carried away by the analysis team, and only a large amount of blood had been coagulated and the yellow and white things exuded a pungent disgusting smell on the scene......

Mu Zishuang bent down and pressed his knees, panting. The exhausted appearance was in stark contrast to Jiao Yan on the other side, who was in high spirits and quickly drew the array runes with his index finger.

Jiao Yan didn't answer, and continued to complete one rune after another at an extremely fast speed, waiting for half an hour. Massive runes are linked to each other and work in turnover.

"Light and shadow tracking circle? The range is 500 meters in circumference, and the time is ...... Six days? ”

Mu Zishuang probed over, and various images flashed in his pupils.

"Because today is the fourth day of the Emperor's Birthday, October 4th, and the first time Gu Salin looked for He Xinhang was before the Yinghong Wenwen exam on October 1......"

"So do you suspect that Gu Salin is the murderer?"

"It's not just suspicion, Zishuang, come and see ......"

The light and shadow echo, the formation starts, and everything is like a silent movie.

Day 1, September 29. He Xinhang refining magic weapons, except for the only time he called his subordinates to buy takeout, he did not leave his room all day, and no other outsiders came.

The next day, September 30th. As on September 29, there was nothing of note.

The third day, the Emperor's Birthday on October 1. In the early morning, there was finally movement, and a person came to He Xinhang's room, and he was also the only person in the seven days before He Xinhang was killed, so it was easy to determine his identity - Gu Salin. Originally, when Gu Salin first came in, He Xinhang still looked like he was ignoring it, He Xinhang threw out the jade slip, Gu Salin took over a few seconds and threw it back, and He Xinhang's face changed greatly when he checked the contents. After talking to Gu Salin for a long time, Gu Salin left. Then He Xinhang locked the door and started refining in the house.

When Gu Salin first entered the door, he was followed by a girl of the same age......

"Stop!"

Mu Zishuang suddenly shouted, his little hands dangling in front of Jiao Yan's face.

"What's wrong, Zishuang?"

"Look at the golden leaves on her umbrella, the old janitor obviously gave the token when he saw the child's umbrella......"

"Huh? Really...... Alas, golden leaves? This, this is ...... I count, one, two, three, four...... Eleven, twelve, there are actually twelve pieces in total, Gu Salin is actually related to this kind of person! ”

Then Gu Salin went up to the third floor, as if he had met two acquaintances, chatting and shopping for a series of rare materials......

"I know that those two people are the champion Long Aotian and the runner-up Qing who played the magic field competition before, and at the same time, Long Aotian is also a very famous newcomer king in Yinghong recently." Mu Zishuang added: "In addition, the materials he chose are, thick rock iron, burning gold, purple cotton wood, Tibetan stone ......."

Then Gu Salin went to the second floor and knocked on He Xinhang's door.

Then it went back to the first scene, and no one else was there throughout the day.

In the end, He Xinhang performed a high-level alchemy secret technique, and completed the magic weapon commissioned by Gu Salin overnight.

On the fourth day, October 2, the second day of the Emperor's Day, the Yinghong martial arts examination. Liu Yiming informed Gu Salin of the completion of the magic weapon, and Gu Salin came to the Alchemist Guild for the second time.

The strange thing is that He Xinhang seemed to stop Gu Salin when he was about to leave, and then Gu Salin seemed to be very reluctant to demonstrate the use and power of that magic weapon. Immediately rushed to the martial arts examination, and when he went downstairs, Gu Salin's face was very gloomy.

After Gu Salin left, He Xinhang greeted someone from the Alchemist Guild, and in the evening, the person from the Alchemy Guild came to send He Xinhang a storage bag, and the materials poured out after opening the storage bag were the same as the magic weapon that Gu Salin commissioned before!

Then, He Xinhang began to experiment with that magic weapon again and again, and no one came during this period.

The fifth day, October 3, is the third day of the Emperor's Birthday. Gu Salin came to the Alchemist Guild for the third time, but this time he went to He Xinhang's room first and quietly pushed open the door, looked up and saw the materials on display, and then left after saying a few words to He Xinhang with a very angry look, and then he went to entrust another alchemy master Zhu Zhu to refine.

"Wait, Zishuang...... Here, you put it upside down...... That's right, it was when Gu Salin first arrived on the second floor. ”

Gu Salin came to the second floor, and his eyes paused visibly as he moved to He Xinhang's room.

"Gu Salin suddenly didn't move, could it be that he thought of something?"

"It's not here, what I'm letting you see is that when Gu Salin first arrived on the second floor, He Xinhang's side!"

Mu Zishuang's puzzled expression was even stronger, and it seemed that she didn't know what Jiao Yan had noticed.

"There's nothing wrong with it, He Xinhang was studying the magic circle on the table in front of the window at that time......"

"Haven't you noticed? Look at He Xinhang's doorknob for yourself, he was locked at that time! ”

"Fighting...... Lock? How the hell did Gu Salin push the door open! Mu Zishuang exclaimed, his body suddenly cold: "Could it be that there is a problem with the door lock?" ”

"Impossible, alchemists need to avoid disturbing when refining, so the Alchemists' Guild has equipped each room with a soundproof and seismic isolation array, not to mention the door as the main entrance...... Playing the door lock means that the alchemist does not want to be disturbed at this time, if it affects the refining, it will not only be a door that can be compensated, which I believe the Alchemist Guild knows better than anyone else, so it is absolutely impossible to have such a low-level problem as a broken door lock in terms of quality. ”

"That ......"

"Don't say anything else, let's move on to ......"

He Xinhang continued to concentrate on studying the use of magic weapons after Gu Salin left, and he didn't sleep all day, and no one except Gu Salin came to him.

The sixth day, the fourth day of October, the fourth day of the Emperor's Birthday, today. After He Xinhang studied the magic weapon for more than ten hours, he suddenly seemed to hear something, and then hurriedly went out of the door, but soon came back in less than an hour. Then he studied the Dharma on the desk in front of the window until ...... in the afternoon

Shortly after, a streamer flashed. The glass had not yet shattered, and the air that had been inhaled had not yet been exhaled, when something suddenly hit at an exaggerated speed, and in less than a breath, it directly shattered He Xinhang's body.

In this way, He Xinhang died, the Alchemy Guild was in chaos, and the president of Kesen City used Jiao Yan, who was the watchdog of the empire, through his relationship, and himself, as an adjutant, followed him without matching his front legs......

……

"That's probably it, so how did you know for sure that Gu Salin was the murderer?"

Faced with Mu Zishuang's entangled questions, Jiao Yan helplessly hung up the dead fish eyes.

"Gu Salin said that He Xinhang told him that a woman from the elf clan had asked about the drawings, so when did He Xinhang tell him?" Jiao Yan tugged at her neckline and said unhurriedly: "The elf woman asked about the magic weapon drawing, that is to say, the time frame must be before Gu Salin and He Xinhang were killed, and after Gu Salin, no outsiders have gone to look for He Xinhang at all, and he has been staying in his room, except for going out twice on the day he was killed, it is impossible to have any contact with the elves during the period, let alone telling Gu Salin, who is deliberately making an alibi in the magic field." ”

"Although it is true that he has been staying in the magic arena since this morning, it is very like deliberately creating an alibi, but it is true that he has never gone out...... How did Gu Salin complete the assassination? ”

"Remember the one I said earlier? Storage bags cannot carry living creatures, but they can carry dead objects of flesh and blood......"

"You mean, that elven woman is actually Gu Salin's puppet?"

"That's right, I'm afraid it's still quite a high-level puppet...... In this way, the murderer's methods and everything we investigated can be straightened out, but there are three last points that I can't figure out. Saying this, Jiao Yan's face darkened, and her face showed a thoughtful expression: "First, why can Gu Salin push open the locked door?" Second, Gu Salin took such a lot of trouble to assassinate He Xinhang, was it really just to kill people? Third, why would a murderer with such a strong sense of anti-reconnaissance make a low-level mistake when he is being investigated? Jiao Yan stopped, turned her head and chuckled: "So I left Gu Salin for a day, if he is really a murderer, he will definitely do something tomorrow......

But the real last thing to see is whether the day after tomorrow Gu Salin will come up with a real magic weapon, speaking of which...... Although the design of that artifact is similar, it is definitely not a product of the South! Although there are many styles of Oriental magic weapons, each of them has a very unique style charm, while Gu Salin's magic weapons have no Oriental feeling at all. As for the sword-based north and the west, which is dominated by array staffs, there is no way to talk about it, so whose hand is his magic weapon blueprint? ”

Mu Zishuang didn't answer this time, especially when she heard the end, she just laughed dryly, she didn't know what she was thinking, she just muttered a word in her mouth.

"Gun ......"

"Zishuang, did you say anything?"

"Ah, me? No, no, did you hear it wrong......" said Mu Zishuang suddenly took out the storage bag and took out a crystal ball from it: "Alas? The analysis team sent a message saying that He Xinhang's autopsy results are out, my lord, let's go back quickly! ”
