The original clothes had already exploded into pieces.

Wang Ye’s upper body and part of his lower body were exposed.

But since there was no one else here, being exposed didn’t matter.

As the bones of his right arm were extensively shattered and his body tissues were completely broken, intense pain instantly spread throughout the entire arm, and blood continuously seeped from the gaps, dripping onto the ground, quickly staining the grass beneath his feet red.

Clearly, the recent "Sonic Punch" had far exceeded his body’s limits. Just the pressure it endured was enough to shatter his body, now comparable in hardness to chromium, into pieces.

This was enough to demonstrate that the extreme speed at the moment Wang Ye threw his punch might have already exceeded ten Machs.

The Mach unit, specifically, is not purely a speed unit but a ratio of an object’s speed to the speed of sound. For example, 1 Mach is the speed of sound, and 2 Machs is twice the speed of sound. The event of the Mach unit’s birth is much earlier than when humans achieved supersonic flight; it was proposed by the physicist Ernst Mach. It was suggested for use by the physics community in 1929 as a form of expressing speed.

Later, when supersonic aircraft were developed, this unit was widely used by countless scientists. They clearly explored what obstacles and problems would be encountered at various Mach numbers, which include three barriers: the sonic barrier, heat barrier, and blackout barrier.

Although Wang Ye’s process of breaking through several Machs was only a moment, he still clearly sensed the feeling of breaking through several layers of barriers.

The first barrier he encountered is the widely known sonic barrier. The so-called sonic barrier refers to when an object’s speed approaches the speed of sound, shock waves appear around the object, causing the air resistance it encounters to greatly increase, putting immense pressure on the object.

Humans first realized the existence of the sonic barrier in June 1945 during a British test flight of the DH-106 when the aircraft approached the speed of sound, and the sudden appearance of shock waves tore the fuselage apart, resulting in the destruction of the aircraft and loss of lives.

British scientists studied the incident and said:

"The speed of sound is like a wall of obstacles in front of the aircraft."

Since then, the sonic barrier has become a professional term to describe this phenomenon.

After experiencing countless hardships, humans finally found a way to break the sonic barrier.

First, using advanced aerodynamic layouts like swept wings to weaken shock waves.

Second, further increasing engine thrust to offset resistance.

Third, developing advanced materials to reinforce the fuselage.

This barrier is not particularly difficult to break through because slightly advanced metal materials and aerodynamic layouts can easily cope with the pressures brought by the sonic barrier.

But for ordinary human flesh, it’s obviously not possible, as the pressure in that instant can instantly tear a person to pieces.

But Wang Ye’s bones and skin were already strengthened to a state comparable to metal. However, their aerodynamic shape doesn’t match that of an aircraft, so the shock wave pressure and temperature he endured would be higher than that of a regular aircraft, though these had no significant impact on him.

The second barrier Wang Ye encountered was the heat barrier that aircraft face when reaching 3 Mach speed.

At nearly 3 Machs, the temperature at the aircraft’s nose can rise to 350°C, which is a significant problem because the fuselage material is aluminum alloy, and 350°C is the limit for aluminum alloy to function normally. If this temperature is exceeded, the strength of the alloy would significantly decrease, causing the aircraft to disintegrate in midair.

If at this point the speed is forcibly increased beyond 3 Machs, the whole plane itself would become a scorching fireball due to air friction. To break the heat barrier, human scientists covered aircraft surfaces with composite heat barrier coatings, used ablation materials to combat heat, and installed heat-resistant equipment and cooling systems to ensure the plane doesn’t get destroyed by high temperatures.

The appearance of the heat barrier created a new sub-discipline in aerodynamics called aerothermal dynamics,

Generally speaking, high-speed aircraft exceeding 2.5 times the speed of sound must be designed according to the requirements of aerothermal dynamics.

If it doesn’t exceed this value, it can be designed according to the requirements of ordinary aircraft.

Naturally, Wang Ye’s skin had neither these heat-resistant devices nor cooling systems, nor the pressure-reducing design of aerothermal dynamics; he could only rely on the high-temperature resistance of his Protective Gang Qi to withstand it. Therefore, at the moment of breaking through the heat barrier, the surface temperature his skin endured even exceeded five hundred degrees Celsius.

Fortunately, his high-temperature endurance limit had already reached four-digit Celsius degrees, so this level of temperature and pressure wouldn’t bring too much intense impact on him, and even in his normal state, his arm throwing surpassed this speed.

After resolving the temperature of the heat barrier, the third obstacle Wang Ye encountered was the so-called blackout barrier.

At this point, the body’s temperature was high enough to ionize the gas molecules on the aircraft’s surface, forming a plasma sheath around the aircraft, which scientists called a plasma sheath.

This plasma layer itself is not harmful but can block signals. Thus, when shrouded by the blackout barrier, the plane would be in a completely uncontrolled state, relying only on existing inertia to fly blindly.

But the blackout barrier had little impact on Wang Ye,

because he didn’t need signals to maintain his detection ability.

The thing that concerned Wang Ye the most was the skyrocketing temperature and pressure after breaking through five Machs. Since the aircraft has excellent aerodynamic design, the temperature and pressure it bears are not considered too exaggerated. The momentary temperature rarely exceeds four digits, and with the advanced anti-high temperature coatings and cooling technology today, it’s easy to withstand such high temperatures without harming the pilot.
