That's right!
The principle of bombardment is to use a small amount of energy from directional detonation to prematurely and controllably destroy the bomb's detonation sequence or key structures.
But this requires pinpointing the most vulnerable, yet relatively independent, point on the 'explosion propagation path'!
Find that point through the casing amidst so much interference from so many lines and switches.
The explosive equivalent and placement method also need to be calculated.
This ensures that the shockwave from the explosion can both cut off the path of the explosive and avoid affecting the sensitive main charge...
This is ten times more difficult than removing stitches!
The risk is a hundred times greater!
Especially!
This bomb must be connected to another bomb on the other side of the collapsed mine shaft.
If something goes wrong here, something else could explode on the other side.
In that case, all seven missing persons could die as a result.
Team Leader Shen, let's be on the safe side and use a slightly more conservative approach!
I don't think it's necessary to complete the bomb disposal within the remaining twenty minutes.
Residents in the city are advised to be cautious and conduct thorough investigations.
Perhaps the next bomb in the city will not cause any casualties.
That would give us an extra hour to defuse the bomb.
That might be enough to figure out the bomb's trajectory.
I feel it's safer!
The two bomb disposal police officers were right.
"Explosion" is the universally recognized "last resort" in the field of bomb disposal, and it is truly "a dance on the edge of a knife".
It abandons the cumbersome and time-consuming conventional bomb disposal methods, attempting to perform a precise "surgical operation" on the bomb in the most violent way.
The goal is to disable the bomb's detonation function before it explodes completely.
However, the risk of explosion is also very high.
One wrong move and you could be doomed.
Therefore, Shen Ting had anticipated their strong reaction.
He neither refuted nor explained, but simply picked up the low-light probe again, his voice calm, as if he had already made up his mind:
"So now I need to find that 'best detonation point'."
To minimize the risk of explosion.
He ignored the anxious gazes of the two people behind him and immersed himself in observing the internal structure of the bomb again.
This time, his goal was completely different.
My gaze cuts through the annoying tangled wires, ignoring the treacherous switches.
The internal contours outlined by the X-ray imaging are combined with the details seen in the previous endoscopy.
Shen Ting quickly constructed a three-dimensional, simplified model of a bomb in his mind.
Modern high-energy explosives, such as TNT or B explosives (a mixture of TNT and RDX), are relatively stable in themselves.
It requires a strong initiation energy to detonate.
This energy transfer follows a standard path:
First, the most sensitive detonator—
These are usually lead azide, mercury fulminate, etc.
Its characteristics include being relatively easy to detonate, having a fast detonation speed but relatively low power.
They are detonated by a detonator controlled by a fuse or an electric spark.
Then, the detonation energy of the initiating explosive detonates the detonating charge.
RDX is commonly used in explosives.
It has moderate sensitivity, but stronger detonation power and extremely strong propagation ability.
Finally, the explosive charge provides a sufficiently powerful shockwave to detonate the insensitive but extremely powerful main charge.
This path, from "fuse → detonator → detonator → main charge," is the bomb's "detonation transmission path," and also its most crucial "spine."
What Shen Ting needs to do is to "explode" a relatively isolated and vulnerable "joint" on this "spine".
Then, a highly concentrated micro-directional blast is used to cleanly and decisively sever this "joint" in one go.
In this way, even if the bomb is detonated, the energy from the explosion will stop at this point and will not be able to reach the main explosive charge.
The "joint" that Shen Ting was looking for could not be too close to the sensitive detonator, otherwise it would be easy to trigger a premature detonation.
However, it cannot penetrate too deeply into the main charge area, as the shock wave may accidentally detonate the main charge.
The ideal location is usually near the junction of the explosive charge and the main charge, or at a weak point in the explosive charge that is easy to cut.
The confirmation of this detonation point was clearly a very meticulous process.

...
Time passed second by second.
Inside the mine, only the occasional soft sound of Shen Ting adjusting the angle of his probe and the heavy, suppressed breathing of the remaining three could be heard.
Although Zhao Gang and Chen Hao were extremely opposed to the plan, they didn't dare to disturb Shen Ting because of his focused state.
I could only watch him operate with bated breath, my palms covered in cold sweat.
Xu Xinyi's gaze followed Shen Ting closely.
She didn't understand the complex structures of those bombs, but she knew Shen Ting very well—
He has always been cautious.
And unless absolutely necessary, they don't like taking risks.
He usually has a strong sense of confidence when he decides to do something.

...
Seven or eight minutes passed slowly in the deathly silence.
Finally, Shen Ting gently tapped a spot on the X-ray screen with his finger.
There, beneath the shadows of the overlapping lines, the outline of a column slightly thinner than a little finger can be vaguely seen.
This is the detonation charge that Shen Ting determined.
It connects to a larger, high-density shadow behind it, which is the junction of the main charge.
There is a slight, seemingly process-induced, internal fitting gap.
