Astonishing!

However, Chen Mo did not adjust the shape of the psychic energy surrounding his body into a teardrop shape.

While the teardrop shape minimizes drag at normal speeds, the situation becomes much more complex once the speed exceeds the speed of sound.

When an aircraft flies through the air, its nose creates a disturbance in the air. This disturbance propagates at the speed of sound in the form of a disturbance wave. When the aircraft's speed is less than the speed of sound, the disturbance wave will propagate directly in all directions and will not affect the aircraft.

However, when an object moves at supersonic speeds, the propagation speed of the disturbance wave is less than the forward speed of the aircraft. As a result, the subsequent disturbance generated by the aircraft will be superimposed with the existing disturbance wave to form a stronger wave. The air is strongly compressed, forming a shock wave.

For supersonic fighter jets, shock wave drag accounts for a large proportion of their flight speed.

To reduce shock wave drag, fighter jets need to be designed to conform to the "area ratio" as much as possible. Simply put, the cross-sectional area of the aircraft should increase smoothly from the nose to the tail and then decrease smoothly until the very end of the tail.

The overall cross-sectional area of the aircraft should naturally be minimized as much as possible.

This is why we see that ordinary passenger planes are more like teardrop shapes, while supersonic fighter jets are flatter and sharper.

So, after trying this method, Chen Mo finally controlled his mental power to form a flat, spindle-shaped shape that could just cover his body. The largest cross-sectional area in the middle of the spindle was roughly the same as the cross-sectional area of his torso, while the front, back, head, and feet gradually narrowed, forming two sharp, sword-like corners.

This shape was adjusted by Chen Mo after experimentation to achieve the lowest possible flight resistance, based on the principle of minimizing air resistance and shock wave drag.

"J.A.R.V.I.S., report the speed."

Chen Mo clearly felt that after changing the shape of his psychic shell, his flight speed increased again. After reaching the maximum speed, he asked J.A.R.V.I.S. again.

"Sir, your current flight speed has reached Mach 3."

Upon hearing this, Chen Mo shook his head with some regret. It was indeed a significant improvement over before, but it was still far from the top speed of Mach 6 of the Iron Man suit.

It seems that long-distance flight still requires the Iron Man suit. At least for now, his own flight speed is not as fast as the Iron Man suit, and it also consumes mental energy continuously. Although the consumption is small, with his current mental energy strength, he can fly at full speed for several hours without any problem. But it is not as simple and convenient as the Iron Man suit.

However, when Chen Mo thought of the Iron Man suit, he quickly had a new idea.

He first slowed down and hovered in the air, then with a thought, he released the Iron Man suit directly from his spatial storage.

A jet-black Adamantium Iron Man Suit instantly appeared in front of Chen Mo, completely enveloping his front half. A series of deep mechanical sounds, accompanied by crisp metallic clanging, followed as the armor plates on both sides of the suit rapidly deformed and closed, completely covering Chen Mo.

All dressed!

The whole process took less than a second!

From the moment the suit was released to the moment the armor transformed and closed, the process was extremely fast, almost instantaneous. This was the result of Chen Mo's continuous optimization and improvement, all in order to minimize the dressing time and prevent the enemy from seizing any openings.

After donning the Iron Man suit, Chen Mo did not activate the thrusters. Instead, he used his telekinesis to lift the suit and himself into the air. This time, Chen Mo clearly felt the increased weight. Although it was not as much as the force he used when flying at full speed, it was not as easy as it had been at the beginning.

Chen Mo himself weighed about 100 kilograms, and with the 200-kilogram weight of the Iron Man suit, his total weight reached 300 kilograms.

However, Chen Mo only felt that it was a bit heavy. With his current psychic power, lifting a weight of 300 kilograms was no problem at all. Although he had not tested it accurately, according to his feeling, the current upper limit of his psychic power to control objects should be around one ton.

When it comes to adjusting posture in the air, the Iron Man suit itself is controlled by thrusters in the hands, feet, chest and abdomen. Although Chen Mo's control ability is sufficient to flexibly control it, it is far less convenient and faster than telekinesis. Chen Mo directly used telekinesis to control the suit to adjust to a flight posture, with his hands still naturally extended to his sides.

Then, under Chen Mo's control, the thrusters on the Iron Man suit's feet, hands, and chest/abdomen activated simultaneously, spewing out blazing white flames and propelling the suit forward at a sudden acceleration.

When the holographic projection inside the helmet showed that the speed had reached its maximum, Mach 6, Chen Mo once again applied his telekinesis to the battle suit, giving it an additional boost.

Once its speed stabilized, the Iron Man suit accelerated again, rapidly increasing its speed until it reached a new speed limit: Mach 7!

Don't be fooled by the fact that the speed only increased by Mach 1. At supersonic speeds, the drag increases more and more with increasing speed, and it becomes increasingly difficult to increase speed further.

In the real world, the fastest fighter jets only reach speeds of Mach 3.2. NASA did build a hypersonic aircraft with a top speed of Mach 9.8, the X-43. However, it was an unmanned experimental aircraft specifically designed to research scramjet engines and had no practical value. Its flight required being carried to an altitude of 100,000 feet by a B-52 bomber, then being taken to a higher orbit and accelerated to a very high speed by a Rocket. Finally, it separated from the Rocket and continued to fly for about 10 seconds, briefly reaching the Mach 9.8 top speed, before losing power and crashing into the sea.

Compared to them, Chen Mo's current speed of Mach 7 is already astonishing, and this is not the end.

Although the shape of the Iron Man suit has been optimized and its drag coefficient is already very low, its main function is still combat. Therefore, the shape cannot be significantly modified in pursuit of low drag. As a result, compared to fighter jets, its flight drag is still relatively high. Although its powerful engine allows it to maintain a high speed, further optimization of the shape could still greatly improve its performance.

Therefore, Chen Mo once again used his telekinesis to form a new layer of "armor" on the outer layer of the battle suit, changing its dynamic shape to a shuttle shape. The flight speed of the battle suit was also increased again, eventually reaching eight times the speed of sound! That is, 9,800 kilometers per hour, nearly 10,000 kilometers per hour!
