Countless fist shadows were stacked on top of each other, as if countless stars were exploding in the void. The ability to accelerate is constantly and continuously exerted, and at this time it is no longer possible to maintain it perfectly in the accelerated world, and they are strongly blocked by the real world.

However, for them with ultimate power, the strongest resistance is only to attract them to burst out with stronger power, and it will never reach equilibrium.

In reality, it didn't take even a second to get started, and the accelerated world was shattered under their intense bombardment, but their battle didn't stop. The void shook like a picture scroll, and where their fists and shadows intertwined, there was a pitch-black lightning dance, which was the ripple of space. A boulder of thousands of squares, half-exposed to the water, was struck by a pitch-black lightning bolt and burst open, and the debris bombarded the top of the cave, accelerating the collapse of the cave itself.

Yukihime and Gan Tian exert a huge force on each other at the same time, and after accelerating the collapse of the world, they inevitably separate. Even though their hands can't make direct contact, they can still exert a huge impact on each other's bodies through the medium of air. The more they increase the speed and power of their punches, the more force they exert on their opponents, and the more they separate. However, the more they separated, the more they had to continue to increase their strength, and the intensity of the increase would not decrease the force acting on each other's bodies.

Depending on the situation they are in at this time, they can get a mathematical calculation problem for the college entrance examination. First of all, it's worth emphasizing that because they are so strong against each other, they can ignore air resistance in other directions, as well as obstacles that stand in their way. Then it is known that the force exerted by them is the same, and that this power is constantly increasing, and the goal they want to achieve is to make the other person receive their own impact at a rate of double per second. Also, the air resistance behind them is linearly related to the quadratic of the speed at which they are moving. It should be noted that this problem does not need to consider the space difference caused by the time difference caused by the moment of jumping from the accelerated world to the real world, and the initial condition is set to one-third of the speed of sound, which satisfies the three laws of mechanics. Find all the unknowns, including the linear coefficients of drag and velocity, the initial values of the magnitude of the forces they superimpose, and so on.

Seconds later, they flew out of the ruins of the Black Jade Prison. At that moment when the suppression was lifted, the power between them skyrocketed again. Every punch almost creates a vacuum, and they are constantly pushing the limits of the medium. However, it turns out that as long as they exist in space, there is no such limit, and even after throwing a fist in a vacuum, beyond the limit of air, there are still other mediums at work. The air seemed to be compressed tens of thousands of times before it erupted, and the thunder was not enough to describe the strong seismic wave.

Their fists were already on fire, and the resistance they endured increased as the speed of their punches increased, and they could only increase the power of their punches even harder. The air was constantly compressed, gathering tens of thousands of times more force, and then blasting out in other directions. However, there was a limit to this, and soon the flames ceased to take the form of flames, but light, pure light.

From a distance, above the ruins, two dots pulled apart quickly, leaving a line. At first glance, there seemed to be nothing in that line, but gradually, the thunderous whistling sound was heard at the edge of the cavern, and the terrifying shock wave was felt.

The water was turbulent, but it was suppressed by the line and rippled, moving in all directions.

The black jade prison gradually collapsed, and even if it was not directly hit, the medium that was constantly exploding above still transmitted some of its power to the ruins. The ruins cracked open a large crack at first, and the cobweb-like cracks spread, and finally, with a bang, the whole thing was reduced to splinters.

The cavern was originally dim, and the line was deduced by something that had been bounced off. Gradually, however, the thread began to glow, as if it were burning, and then it became pure light again.

At this point, it had been less than ten seconds since they began to bombard, but the energy they had leaned into this space far exceeded the sum of their previous battles. At this point, no one can stop it. Whoever is weak with a punch will be beaten into ashes by the opponent's punch. The power has accumulated to such an extent that none of them can let go, but they can only continue to use the power, increasing the power again and again until the strength is exhausted.

They crossed the black jade prison, and after breaking free from the force of the bondage, the acceleration between them doubled at once, and in an instant they crashed into the edge of the cavern, and then continued deeper without hindrance.

Even if they are thousands of kilometers or 10,000 meters apart, their principle is to only increase and not decrease.

In such a situation, for every doubling of distance, the required force increases by several times or even tens of times, which is a geometric superposition, quickly calling for their limits, calling for the limits of ultimate power.

The two ends of the cave were pierced by them, and there was a stream of water between them, and without accident a huge hole was punched, and then the water was agitated, and after a few falls, it was knocked away several times, and each time it became more and more violent.

The earth shook, and the cave was ready to collapse completely. However, the two guys created a diffuse impact column inside it, and everything that came close was bounced off.

The formation is the same as them, the more it is bounced off, the more mass it has to be pressed, and the more it is compressed, the more mass it will have to provide resistance. No one is willing to admit defeat, so the only way to do this crazy ultimate power is to continue to superimpose.

Another second passed, and the line was really glowing, heating, and the gas was ionized, releasing a large number of high-energy particles. The earth was also beaten badly, again and again, and each time more and more fierce. The energy was close to the power of an earthquake, and strange ripples were swaying on Changming Lake far above, and some aquatic creatures had a premonition and jumped out of the water.

Hojo Reika grabbed one of them and frowned at Akane Takeda, "What are they doing down there?" I had a sense of foreboding. ”

Takeda Akane lifted her glasses and said seriously, "Minister, I feel the same way. ”

No one noticed that their boat was drifting towards a whirlpool in the lake.

……

Go back to the depths of the earth.

That's how the battle should be! Whether I won or lost, I did feel the climax that I hadn't seen for a long time, that heartfelt warmth. Isn't it just for this moment to come back to the world? If that's the case, they're not bad for me! ’

Yukihime thought frantically in her heart, her body had already been excited to the peak. She was caught up in an equation of times, demanding more and more strength, constantly calling for her limits, and she also wanted to see how far her limits, the limits after betting all of them, could go. Even if she wants to shatter this world, she doesn't care at this time, and that extreme pleasure is her instinctive appeal at this time.

Finally, she arrived. The last punch seemed to open a dark door, allowing her to see the familiar black abyss again.

I didn't expect that I would have such a moment of enjoying the battle, and this feeling of being able to overcome the physical orgasm is the root of what keeps those battle maniacs fighting? I seem to understand their thoughts a little bit, and I like this kind of battle, a battle that can't be stopped. In that case, it's better to use this to make a decision. ’

Gan Tian thought to himself. He had never been so involved in the battle, getting rid of that feeling of darkness and cloudiness, and at this moment he held the real power in his hands, and felt the thrill that seemed to surpass everything.

With the last punch, Gan Tian and Yukihime hit out at the same time.

In a moment, the thread connecting them was extinguished. It was as if a dark door had opened, allowing them to see the incomparably deep black abyss for the first time in a long time. In the eyes of the Phantom God, at that moment, they didn't just hit the power, with that last punch flying out, there was something on another level. Not only the physical impact, but also the release of light and heat from their souls.

So at that moment, the light and heat generated by the friction were taken away. At the moment of the collision of extreme forces, there was no fierce conflict, but it was like blending, quietly annihilated.

With the darkness of that line, all the light in the cavern seemed to be taken away at the same time.
