"Kill vampires and get traits: Enhanced Physical Fitness (5X9), Air Elemental Affinity (2), Super Self-Healing (2/10)."

In twenty days, after driving 2,000 kilometers all the way and traveling through more than a dozen towns, Qin Heng's strength has been greatly improved.

After killing more than 20 vampires, he gained a total of 9 characteristic fragments, among which the characteristic fragments with enhanced physical fitness made his physical fitness reach the level of 160, and his comprehensive score was eight times that of Captain America.

The Air Elemental Affinity has accumulated (8/10), increasing his speed even more.

And the newly acquired trait is super self-healing, and it is also a trait that he has been longing for before.

Qin Heng, who has the 'immortal body without headshots', combined with the enhancement of these two characteristics of physical fitness, has the ability to heal himself is already a non-human existence, and after his heart was pierced by the sword, it only took two days to heal himself after consuming magical energy.

And now, even if he only got two super self-healing characteristic fragments, his self-healing ability has also risen to a higher level, and if there is another injury to his heart being pierced by a sword, he can completely recover in two days without spending magic energy to accelerate self-healing.

There is also a reason for the re-enhancement of physical fitness.

If he is willing to expend magic energy or the power of faith energy, his self-healing ability is no weaker than that of a vampire.

[After this characteristic is superimposed, the heart penetrates this injury, and it can completely heal itself in an hour or two, and the rebirth of the severed limb can also be done, if you count the energy value of magic energy or the power of faith to enhance the self-healing ability, I am not much worse than Wolverine and Deadpool.] 】

Qin Heng sat in the co-pilot, supported Daisy to drive to the next destination, and began to practice himself.

Using magical energy to create a barrier to isolate his brain, he doesn't need to worry about his thoughts being sensed by vampires with prophetic abilities, which is actually not a big consumption.

The co-pilot's window was open, and Qin Heng's hand stretched out of the window, swaying as if he was bored.

"How fast do you like to drive?"

Twenty days also made Daisy and Qin Heng familiar, and even dared to joke with Qin Heng and asked: "40 yards or 60 yards or 80 yards?" ”

Qin Heng glanced at Daisy, and Daisy decisively shut up and drove seriously.

Familiar, but Daisy has also learned to shut up when it's time to shut up, and open up when it's time to speak.

Qin Heng felt the high-speed flow of air elements outside the car window, and the characteristic magic energy was slowly output, capturing some air elements and then starting to compress and set.

The construction diagram, principle and other information of the jet engine have all been found out and sorted out by Daisy, and Qin Heng has also memorized it by heart.

The overall improvement of physical fitness, although it cannot improve IQ, can improve memory, information analysis and processing ability, so that Qin Heng, a junior college student majoring in computer science, has the ability to build an 'air engine' by himself.

The principle of a jet engine is simple: the action of force is mutual.

If no one controls the nozzle, the high-pressure water pipe will only run around due to the water pressure, and even if the person holding the nozzle is not strong enough, it will push the person away.

Qin Heng needed to do more than just make a high-pressure water pipe, although he could compress the air and then release it to generate a strong power, compressible air took time, and it also took time to capture the air element, which would cause the kinetic energy obtained in this way to be intermittent and not stable enough.

And jets alone cannot provide the kinetic energy of high-speed flight.

What he needs to do is to use magical energy to stabilize the four working processes of a jet engine: air intake, compression, combustion, and exhaust according to the principle of a jet engine.

One of the most difficult to do is combustion, which is to simulate the 'internal combustion engine' of an engine.

Under normal circumstances, even the temperature of the combustion chamber inside the engine of a fifth-generation fighter is less than 2000 degrees, while the temperature of a general turbofan engine is 1400 degrees - 1700 degrees. And the flame magic that Qin Heng was able to create could reach this temperature, and the temperature of the scorching dragon flame could even reach 4,000 degrees.

Therefore, the difficulty is not in the temperature, nor in the conversion of heat energy into power, but in the air element 'engine' structure made by Qin Heng, which cannot withstand such a high temperature.

From a scientific point of view, it is the development of materials science that restricts the development of engine manufacturing technology.

Because Daisy was next to him, Qin Heng was only compressing the roundness of the air that seemed to be an invisible substance, and he didn't use magic energy to create flames.

[If the propeller is made purely from the air element, although it can also provide some flying ability, because of the existence of the propeller and the control of its high-speed rotation, it needs to consume too much magical energy, and it will not be able to fly for a long time, and the speed will be very slow.] The same amount of magic energy consumed to create flames can generate much more kinetic energy that can be converted into high temperatures, both in terms of flight speed and flight distance. 】

[However, I have compressed the air to the extreme I can compress, and I still can't withstand the power generated when the flame's high temperature converts kinetic energy, let alone the dragon flame, which is hotter and can produce more powerful kinetic energy. 】

Qin Heng looked at the 'Air Element Jet Engine' that had stabilized suspended in the air in his hand stretched out of the car window, and began to think about how to solve this problem.

[Materials science is one of the main disciplines restricting the development of science and technology, even controlled nuclear fusion technology, in the final analysis, it is because of the constraints of materials science, it is impossible to manufacture materials that can withstand the high temperature of controlled nuclear fusion. To put it simply, scientists want to put the sun into a box, and then convert the heat energy generated by the sun into electricity and kinetic energy, but scientists don't know how to make that box, and the existing materials can only resist a few seconds. 】

[And my current problem is that I can't hold it for a second, otherwise, I can fly in a second.] 】

The combination of science and magic was much more difficult than Qin Heng had imagined.

[How can the air element withstand the high temperature of the flame?] 】

Scattering the air engine that had been formed in his hand, Qin Heng's hand stretched out outside the window felt a strange touch.

The constant wind is shaped by the shape of the palm, and it has a rounded feeling.

Qin Heng suddenly figured out the question that Daisy asked him just now, in the case of different speeds, the touch of air based on the shape of the palm is also different, and the specific difference is in size.

Glancing at Daisy, who was driving, Qin Heng was suddenly stunned.

[Continuous? 】

Looking at his windward palm outside the car window, as well as the continuous touch in his palm, Qin Heng's eyes brightened a little.

[It is true that the air element cannot withstand the high temperature and kinetic energy of the flames, but a cloud mage like Eastlong can defeat the fire warlock, because Eastlong can continuously create an air element barrier to block the fire damage of the fire warlock. 】

[A drop of water can't extinguish a fire, but what if it's a continuous raindrop?] It is true that the engine made of compressed air elements cannot withstand the high temperature of the flame, but when the air element is destroyed by the flame, I continue to replenish the compressed air element? 】

[As long as the flame can be controlled within a certain range, and then the kinetic energy generated by it can be continuously output, relieving the internal pressure and strengthening the air element barrier, isn't it equivalent to obtaining a stable engine?] 】

Feeling the touch in his hand increase, Qin Heng looked at Daisy, who had secretly sped up the car.

"Find a place to park."

Daisy was stunned for a moment, looked at the wilderness around her, coughed dryly, and said, "Why don't we get to the town and find a place to live...... It's also easier to take a shower. ”

Qin Heng frowned: "I said, stop." ”

The off-road vehicle braked to the side of the road, and Daisy took a deep breath in anticipation.

The co-pilot's door was opened, and Qin Heng got out of the car and ran wildly towards the wilderness, and disappeared into the woods not far away after a while.

Daisy was dumbfounded: "Did he drill into the grove?" Shall I follow? ”
