Over, Shen Yunjiao took out a ball of strings from his cuffs and said, "My lord, this is the string used for the long bowstring of the ordinary cottonman, let's try how lethal this string is." ”

Then, Shen Yunjiao replaced the strings of Zhao Lin from earlier, then put the wood on the shelf, repeating the action just now.

Only this time, the wood did not break, it left a deep trace.

screen, all the ministers are puzzled, aren't they all the same strings?

"Zhao Lin, can you explain to Master Wen why your strings are so lethal?" Shen Yunjiao asked.

"My lord, how do the grass people know," Zhao Lin said.

Shen Yunjiao didn't say anything, just cut off a part of Zhao Lin's string, put it on a plate, and lit it with a fire fold.

"I thought that with the right mechanism, ordinary strings could be used as a killer, but when I tried it and found that it didn't work, I thought my inference was wrong. Unfortunately, I discovered the secret of this string. ”

At the end, Shen Yunjiao used tweezers to clip out a piece of charcoal black, as thin as a hair, in the saucer, and raised it for everyone to see.

"This is the mystery of Zhao Lin's bowstring, ordinary strings, there will never be such a wire in it, not only the cost is too high, but this wire is not something that ordinary people can get.

Because this iron wire is not an ordinary iron wire, but forged from dark iron, iron wire of this material usually does not appear in the people, if I remember correctly, such a string will only appear in the ordnance prison. ”

Shen Yunjiao's words made the emperor and others behind the screen feel that this case may not be simple.

And Zhao Lin, at this time, did not have the previous calm in his eyes

"Knowing that this wire was unusual, it might have come from the Ordnance Superintendent, so I asked my father to go to the Ordnance Superintendent to check it, and the result was really something unusual.

There is a craftsman in the ordnance superintendent, named Wang Xian, who is proficient in dark iron forging, and this person is none other than Zhao Lin's younger brother of the same father and mother.

Zhao Lin, I really don't know if this younger brother of yours is fortunate or unfortunate to have an elder brother like you. ”

Over, no matter how nervous Zhao Lin was, Shen Yunjiao said to Wen Yue: "My lord, the lower official requests to summon Wang Xian, the weapons supervisor, to the court to inquire about the case." ”

After listening to Shen Yunjiao's words, Wen Yue also saw the nervousness on Zhao Lin's expression, and also knew that this Wang Xian Xu was the key person in this case.

"Pass on the decree and summon Wang Xian to Dali Temple." Wen Yue said.

The ordnance supervisor and Dali Temple were not far apart, and soon Wang Xian followed the yacha to Dali Temple.

Seeing Zhao Lin kneeling on the ground, grief and remorse flashed in Wang Xian's eyes.

"Xiaguan, the ordnance supervisor Wang Xian, I've seen Lord Wen," Wang Xian knelt on the ground and said.

Wen Yue didn't miss the emotion in Wang Xian's eyes before, and said quietly: "Show Lord Wang a seat"

After Wang Xian sat down, Wen Yue instructed the yacha to hand the previous Xuantie wire to Wang Xian, and said, "Lord Wang, your ability to forge Xuantie is full of praise, can you help the official to see, this Xuantie wire, but it is from the Ordnance Prison, from the hands of Lord Wang?" ”

Wang Xian took it, and without looking at it, he knew that the string was from his hand.

"Lord Hui, this is indeed my hand," Wang Xian said.

"Then Lord Wang, do you remember, who did you give it to? You know, this string is in a murder weapon. Wen Yue said
