3487 meters per second per second, nearly ten times the speed of sound, which is Zhang Tie's flying speed.

At 1,689 meters per second, nearly five times the speed of sound, it was the speed at which Zhang Tie threw his flying spear in a static state.

The moment the flying spear left Zhang Tie's grasp, the relative speed with Zhang Tie was 1689 meters per second, while its true speed was 5176 meters per second.

The gravitational acceleration brought by the process of landing at a height of more than 1,000 meters is negligible,

When the 56 kg flying spear hits the building that Zhang Tie chose at will, its kinetic energy is 56 divided by 2 and multiplied by the square of 5176.

As soon as the flying spear was removed from his hand, Zhang Tie already knew the kinetic power contained in his flying spear-750147328 joules, under the powerful calculation of his mind.

The kinetic energy of more than 750 million joules is almost equivalent to the equivalent of 180 kilograms of TNT explosion by the standard before the catastrophe.

Of course, in this era, there are no explosives other than alchemy bombs, and the destructive power of kinetic energy attacks is more concentrated, and the lethality of single targets is greater.

The flying spear hit the twenty-story building, and the ten stories above the entire building collapsed in an instant, dust was flying, rocks were scattered, and most of it collapsed.

Zhang Tie then threw the other two flying spears in his hand, and continued to hit the collapsed building. Under the damage caused by the three flying spears, the entire building collapsed and collapsed, and it was still on the ground. A large pit several meters in diameter was left.

Later, Zhang Tie tried the ability of Shenyu to control the attack of the object during the flight.

Zhang Tie found that the flight inertia of his body's speed cannot be transmitted to the object controlled by his mental power. When he uses his mental power to control an object, if the object is in the same direction as his own flight, its speed can only be the same as his own. The maximum flight speed is equal without exceeding their maximum flight speed. Only when you throw a flying spear, your body's flying speed and inertia can be transferred to the flying spear.

Under normal conditions, the kinetic energy produced by throwing a 56 kilogram flying spear at a speed of 1,689 meters per second per second is 79876188 joules.

At ten times the speed of sound, the kinetic energy produced by the flying spear of the same weight thrown by him is 750147328 joules.

Comparing the two, the power of the same flying spear is 9.39 times more powerful, and if your flying speed can be increased, the difference will be even greater.

The power of the flying spear was beyond Zhang Tie’s expectations, but it was still a little different from what Zhang Tie had imagined. Zhang Tie felt that the 50 kilogram flying spear was too light, and it was completely impossible to use the kinetic energy in his own hand. Power, there is still a lot of power in his body that hasn't been fully used. The kinetic energy of this flying spear strike can be increased many times.

When you use the flying spear to attack under the flying state of the gods, this is the fastest, easiest and most powerful kinetic energy attack you can output.

And once I can easily kill a black iron knight in this state with a flying spear, then, can I become the nemesis of all the black iron knights, and treat all the black iron knights of the demon race like an ant? Pressure? You know, this is something that even a knight in the sky may not be able to do.

Zhang Tie was excited. He couldn't help but feel that a golden avenue on the road of cultivation appeared in front of him. This golden avenue was reduced from complexity to simplicity using only two elements of speed and strength. , Can defeat and crush all opponents, and speed and strength are his biggest advantages now, the way of fighting under the rule of the gods. At this point, he can enter a new field and world, and his hands , Once again added a powerful hole card that can change the situation.

I rely on, I can almost become a humanoid hypersonic strategic bomber that launches kinetic energy weapons in the future!

Looking at the collapsed building again, thinking about his own gains in his mind, the next second, Zhang Tie withdrew from the realm of soul catastrophe...

...

Zhang Tie opened his eyes and saw Heller under the small tree, as if he knew he would wake up at this time.

"This time entering the realm of soul catastrophe, the castle master seems to be very rewarding!"

Zhang Tie stood up with a confident smile on his face, "I just suddenly found out what I should do in the future..." After saying this, Zhang Tie looked at the calm and calm face of Heller seriously. With a smile and the wise gaze in his eyes, he suddenly felt, "Did you already know the mystery of kinetic weapons? You should tell me earlier. If it weren't for the expeditionary army that raided the Holy Light Empire this time, maybe I wouldn't It turns out that I can have such a powerful means of attack!"

"When the castle owner uses the power of the divine master to achieve faster and faster flight speeds, the mystery of the so-called kinetic energy weapon is a layer of window paper for the castle owner. It is only a matter of time before it is pierced. To tell you prematurely, it may affect your practice and exploration in martial arts. This is not a good thing. In any case, even if you are a knight, you need to observe the world with your own eyes, use your own brain and Perceiving and thinking about the world, the experience and insights gained in this way will be more real and reliable. If you think about it, Lord Lord, if I told you that you can choose other attack methods after reaching the hypersonic flight state, you Will there still be such excitement and profound insights as today?"

"Well, you are right!" Zhang Tie did not argue with Heller on this matter, because this is Heller's consistent style. Heller never said a word about his own practice, he just adhered to it. The duty of the steward of the Dark Iron Fortress is at most just a reminder from the side, "Then do you think there is a future for the kinetic energy attack?"

"The power of a kinetic energy attack is closely related to power and speed. The so-called extreme power is close to Tao. Don’t Lord Lord want to see what the scenery at the limit of speed and power is? Moreover, the kinetic energy that the Lord now masters Attacks can already be comparable to the small tactical nuclear weapons before the cataclysm. In the future, with the improvement of the strength of the Lord Lord, the power of the Lord Lord’s kinetic attack will become stronger and stronger. Such a powerful, concise and efficient attack method, In the holy war, how can there be no future? Looking at the human race, in addition to the master of the castle, has the master of the castle seen other people have the same means?"

Zhang Tie understood what Heller meant. This was the first time Heller had such an attack on Zhang Tie. Heller's words further strengthened Zhang Tie's thoughts.

There is definitely something going on this road.

"Speaking of the increase in kinetic energy attack power, I think the gods of the Holy Light Empire finally left me something!"

Zhang Tie looked up, looked at the brilliant fruit of brilliance and the fruit of judgment on the little tree, his expression in his eyes suddenly became warm...
