The Eminence in Shadow: Master of Garden: Main Quest Ch.24: Covert Combat

The fight didn't happen on a train; they were in pursuit of a carriage.
From the web novel:
“If you don’t come to me, then I can just come to you.”
“Eh………….!?”
John Smith slightly moved his finger.
At the same time, a thread wrapped around No.664’s neck.
No way--since when!?
Moreover, we should already be outside his Maai.
“Who said that the length of each and every thread is the same? Naturally its thickness is also different.”
“No way--!”
Looking closely at the thread wrapped around her, she noticed that it was extremely thin and very hard to see.
The strings they have seen up until now were the only ones that they were allowed to see.
“Don’t tell me, from the beginning………”
“Yes……from the beginning.”
No.664’s actions were manipulated from the start.
While her expression distorted due to the humiliation, the thread around her neck started to tighten.
Highly concentrated magical power is passing through the string. If he adds only a little more strength, her neck would be cut through.
“If you are going to kill me, then do it already. I don’t have any intention of talking.”
She glared at John Smith.
No.665 and No.666 were also bound. They’d already made up their minds.
Strength was being added to the threads.
At that moment, No.666 moved.
She rushed out from the front.
She simply came at him before he could pull the threads tight.
“Haaaaaaaa!!”
‘Faster, just a little bit faster--.’
She rushed at John Smith.
“Correct….”
But his stance didn’t waver.
He just pulled a finger on his right hand lightly.
“But who said that there was a thread only around your neck?”
No.666 suddenly fell.
She collapsed, and was made to float in the air with an unnatural pose.
A number of strings had already been wrapped around her limbs.
Naturally the other two were in the same state.
“Kuh…! Kill me!”
No.664 said as their movements were completely sealed.
However, he just tightened the strings and did not kill them.
“There is no meaning in killing you guys. Even if I were to kill you, others will come again, and so, this is just a warning. That’s all there is to it.”
And expressionlessly said.
“Don’t get in the way.”
With those words, he released them.
“*Cough*,* Cough*”
Despite her continuing to cough, No.666 glared at John Smith.
No.664 instantly leapt.
And held down No.666.
“Stop it already! We’re withdrawing.”
“---!”
No.666 bitterly lowered her face.
John Smith….. we have to inform Gamma-sama.
As long as he’s out there, the source of the counterfeit bills can’t be found. And the fact that there exists a person with that level of skill means that another powerful organization also exists out there.
No.664 watched John Smith’s figure as he left.
