Speaking of lightning.

Here we must first address a common misconception:

That is, the explosion speed of lightning is not the speed of light; its propagation speed is the speed of light.

A complete lightning is composed of two parts, namely the leader and the return stroke.

The former is when the air ionizes to establish a path, and the latter is the current flowing from the ground to the clouds.

In terms of speed, the former is slow, and the latter is fast.

The average speed of the leader process is 1.5×10^5 meters per second, about 1/2000th of the speed of light.

While the speed of the return stroke is much greater than the leader speed, almost 1/10th of the speed of light.

Therefore, theoretically speaking.

As long as the computational power of the equipment is sufficient, it is possible to humanly locate the lightning's strike point.

And coincidentally...

The rabbits can indeed achieve this currently.

The technical support comes from our current T1 supercomputer:

Divine Power Taihu Light.

Of course.

Currently, the one in charge on the ground is not Taihu Light, but Tianhe-2.

Tianhe's computing power load rate remains around 60-70, with about 4%+ used for weather model calculations.

In the typhoon-prone summer season, it can sometimes increase to 7% or even 7.5%.

After the recent torrential rain in Central State, Tianhe's computing power was unprecedentedly allocated to weather simulation—a specific power ratio isn't clear, but it's rumored to be between 8.5% and 9.5%.

In summary, Tianhe ultimately predicted weather changes within 72 hours with an accuracy rate of 86%.

Don't think 86% is low, the computing volume of such simulations is unimaginably large.

With the current level of technology reserve.

Even if Tianhe put all its computing power into weather simulation,

it can only interfere with the formation of a small acid rain area of about 1 square kilometer using non-chemical means, with extremely low rainfall.

This is also why when a certain Bilibili UP talked about weather weapons, professional experts rebutted it so harshly they couldn't recognize their own mother.

This is actually quite interesting.

In some people's mouths, the eagle's technology level basically jumps back and forth between primitive man and the Trisolarans...

Either it's so primitive it's not even as good as Ah San, or it's so advanced it seems like they signed an agreement with aliens or dug up the legacy of the Indian Multiverse Empire from a pit.

Rationally speaking, excessive belittling or excessive imagination and praise are both unwise.

The so-called long-term vision doesn't mean you should see all the way to Andromeda at once....

However, difficult as weather simulation is.

Dynamic capture of lightning is still relatively simple, and we have even completed an artificial lightning explosion experiment.

Locating lightning strike points is different from intercepting missiles; it can be calculated through a magnetic sensing model.

Here we have to mention a renowned set of equations.

They are called Maxwell's equations.

In 2004, the British scientific journal "Physics World" held an event:

Letting readers select the greatest formula in the history of science.

Guess where Maxwell's equations ranked?

The final result was...

Maxwell's equations surpassed the mass-energy equivalence, Euler's formula, Newton's second law, the Pythagorean theorem, Schrodinger's equation, etc., ranking first.

This shows its influence.

The significance of Maxwell's equations in physics is that they describe electromagnetic interactions from the perspective of flux and vorticity, that is, from the field's angle,

revealing the principles of electric motors and generators, and predicting the generation of electromagnetic waves.

Considering some students may not understand this passage, let's be blunt:

Without Maxwell's equations, you wouldn't be able to watch small films in this lifetime—because cellphones might not have appeared at that time, let alone smartphones.

Based on the second item of Maxwell's equations, the extension of Gauss's theorem in magnetic fields, and substituting into the quantum field, an interesting result can be derived.

The fractal structure of lightning exhibits scale invariance, a feature of continuous phase transitions, which can be explained by resonance-percolation.

This is the currently widely accepted principle of lightning formation.

Of course.

There is still some distance from a consensus; based on the voting results from 2018, it has about 75% support.

Once the structural principle is determined, the rest becomes very, very simple.

As everyone knows.

Atmospheric molecules can be regarded as barriers encountered by charged particles composing the current, and the region between adjacent barriers can be seen as a potential well.

If a particle's energy is near a certain bound state energy level within, the tunneling probability will approach 1, or in other words, resonance tunneling occurs.

This double barrier structure resonant with particles can randomly form in the atmosphere, with discharge intensifying thermal fluctuations.

And gradually forming an ordered structure on a larger scale.

This is, such double barrier structures appear periodically in space, ultimately undergoing a percolation phase transition, and an extensive fractal conductive channel is formed.

This is the core technological foundation of the rabbits' 'transaction' this time.

Otherwise, without capturing dynamic lightning strike points, you'd either do nothing and get struck by lightning, or directly lock a specific area to attract lightning like other Tribulation Crossers.

Returning to the secret room.

At this moment, Ma Ning is introducing to Yang Zhengchu:

"The Divine Power Taihu Light Supercomputing Array is a treasured artifact of the Wind Spirit Moon Shadow Race.

The Yang Clan Elders can regard it as a sort of calculation deduction array.

Once this array is operational, it can pre-judge the strike point of celestial thunder.

And once we can capture the lightning strike point in real-time, we can proceed with the next part of the plan."

Yang Zhengchu has more or less caught up with Ma Ning's train of thought now, and he pensively said:

"Shopkeeper Ma, I seem to understand a bit of what you mean...

So first calculate each round's eighty-one celestial thunders' strike points through the calculation array, then isolate seventy-two of them, letting the remaining nine fall into the net?"

Ma Ning gave him a surprised look, not expecting that this big shot understood much more than he and the command center anticipated:

"Correct, exactly so."

Upon receiving Ma Ning's affirmation, Yang Zhengchu further asked:

"Shopkeeper Ma, not to mention how long the Magical Artifact for blocking the Thunder Tribulation can hold.

Just those nine celestial thunders left inside.... how do you plan to weaken them?"

This time Ma Ning did not answer him directly but instead took out...

A funnel and two plastic bags of sand.

Ma Ning first poured one bag of sand into his hand, then released his left hand.

Swish——

The sand instantly hit the ground, scattering into a pile.

Then he picked up the funnel and poured the other bag of sand into it.

Soon.

The upper part of the hourglass was filled with sand, with a fine sand line flowing out from the bottom of the funnel.

Fine, rapid.

But the volume was small.

Seeing this situation.

Yang Zhengchu had a flash of understanding in his eyes and suddenly looked at Ma Ning:

"Shopkeeper Ma, are you suggesting setting up a channel for the Thunder Tribulation, allowing it to fall controllably bit by bit?"

Ma Ning nodded gently and said:

"Yes, hadn't I mentioned to you before?

The energy of the Thunder Tribulation—or rather a part of its main energy, derives from its electric potential energy.

So long as we use some means to extend its potential energy difference from instantaneously.

During the entire process, the total energy difference of the thunder penalty won't decrease; it's just prolonged.

This way, without affecting the body-tempering material inside, we can reduce the damage caused by lightning to the body.

Just like the sand just now.

One falls instantly, the other slides down slowly.

The two would have no difference in total amount, the only difference is the time consumed.

And time...

Happens to be the least important factor in the Thunder Tribulation.

Clan Leader Yang, you should also know.

It is rumored that in ancient times.

Some cultivators even spent whole days crossing the Thunder Tribulation and eventually succeeded in breaching a realm."
