Chapter 198

"Miracle! Dear viewers, this is really a miracle. The evangelical soldier is much faster in the water than other racing cars. He is catching up with other competitors!"

"Catch up, the gospel soldier has caught up with the fire hydrant. He will catch up with Pegasus soon!"

"Now the evangelical warrior has jumped to the fourth place. Be careful with the three cars in front of him, but there are only the last 200 meters left from the end of the race. Can the evangelical warrior break through the siege and change his life against the sky?"

"Super! Over! In the last 50 meters, the evangelical warrior surpassed Song Jiang and now ranks second. However, it seems difficult to surpass the first whirlwind warrior, because the whirlwind warrior is only 10 meters away from the final destination, and the champion is basically no longer in suspense!"

"No, my God, the speed of the whirlwind warrior is slowing down rapidly. He stopped!! it seems that there is something wrong with the whirlwind warrior's engine, and it seems that our champion is about to change dramatically... Let's congratulate the gospel warrior on his amazing reversal! He has become our champion!!"

"The gospel warrior is the champion!!!"

The 4WD fighter finally shouted this sentence in a hoarse voice. Liu Nian looked at his car incredibly. He thought he would win the top 10 at most. Unexpectedly, he finally stood on the podium of the champion.

At this time, cheers broke out in the whole stadium. No one likes to watch the smooth sailing game. Only the game of winning the championship in adversity and amazing reversal is the game that the audience likes to see and talk about most.

Today's game was the best amazing reversal. After the worst start, the evangelical soldiers actually completed the reversal with amazing underwater speed and won the championship, which made all the audience cry wildly.

The other contestants around looked at Liu Nian curiously and incomprehensibly. They wondered why the speed of Gospel soldiers was so fast underwater, which was unscientific.

"Liu Nian, can you share with us the secret of your transformation of 4WD?" the 4WD fighter put the microphone in Liu Nian's mouth and asked curiously.

"Maybe it's because my 4WD is heavy!" Liu Nian thought for a while, and then said, "in addition, I temporarily modified the 4WD shell, which should also matter!"

Liu Nian said that in front of the camera, he took off the car cover of his car. When he observed nearby, he found that Liu Nian's car cover had indeed been urgently modified. He actually cut off more than half of the car cover directly, leaving only an arc car cover and removing the whole rear tail wing. Finally, the car cover can only cover the car reluctantly.

"This is the most suitable shell shape for underwater action!" Liu Nian explained with the shell. "This shape has no superfluous things to create resistance, which can maximize the reduction of water resistance. It involves some simple hydrodynamics, specifically..."

Liu Nian talked a lot of knowledge about fluid mechanics into the microphone and listened to the audience's confused face.

"Well, Liu Nian, you just said that your car is heavier than others. Why?" the 4WD fighter quickly turned off the topic and asked.

"Because my racing engine can't be waterproof, I can only use some other means!" Liu Nian spat out his tongue, and then skillfully opened the rear compartment cover of the engine in front of the camera lens. Until this time, people found that the whole rear hood was filled with a large lump of yellow things, Fill up the whole rear hood.

"This is... Lubricating oil?" the 4WD fighter smelled it and said in surprise.

"Yes, this is water-insoluble lubricating oil. At the same time, the lubricating oil is also non-conductive. I think as long as I fill the whole rear engine room with lubricating oil, then water cannot enter the rear engine room. At the same time, the lubricating oil itself is non-conductive, which will not affect the normal operation of the engine, let alone the output power of the engine!"

"In addition, at the position where the battery contacts the metal sheet, I am also coated with lubricating oil, and the whole battery compartment is covered with a large amount of lubricating oil. A circle of adhesive tape is wrapped outside to ensure that it will not lose, so as to maximize the output power of the engine!"

"However, because so much lubricating oil is used, the speed of the engine will certainly be affected. In addition, the weight of the car has seriously exceeded the standard, resulting in a little slow speed at the beginning of the track!"

"Fortunately, the venue can provide unlimited lubricating oil for us to transform 4WD, otherwise I can't get such lubricating oil!" Liu Nian whispered, as if he was afraid that the government would come to him to lose money because he used too much lubricating oil.

"Lubricating oil, this guy..." Jia Yapeng was stunned when he heard that he filled the 4WD Engine with a lot of lubricating oil to prevent water... Jia Yapeng suddenly felt that he should find this little guy to be the screenwriter of 4WD brothers. Jia Yapeng couldn't think of such a coquettish operation!

[PS: lubricating oil waterproof is a coquettish operation put forward by a friend when talking about four drive. It has never been verified. It is completely nonsense by the author Jun. please don't try it in reality, otherwise you will bear the consequences.]

"Then why does the speed get faster after the weight increases?" the 4WD fighter asked after thinking about it.

"I think it's because the 4WD with heavier weight has stronger grip under the water!!" the little guy thought about it and said, "the 4WD is very easy to slip under the water. The faster the speed of the motor is, the easier it is to slip. On the contrary, the 4WD with heavier weight can firmly grasp the ground."

"In addition, when driving underwater, the torque provided by the engine is more important than the speed. It's like when going uphill, the car with high speed has difficulty in driving and climbing. Only the car with high torque can easily climb one hillside after another!"

"Driving in the water is like climbing on a mountain. It has to bear a lot of resistance to move forward. So I adjusted the engine before, rewound the coil, adjusted the torque of the engine to the maximum, and reduced the speed of the engine, which is also an important reason“

Without the slightest concealment, Liu Nian revealed all the modifications he had made to the 4WD, which not only made the surrounding players and audience suddenly realize, but also convinced him.

All the modifications were done by himself. He can even wrap his hands around the coil to change the operation of the engine. Liu Nian is the champion!!

————————————

With the end of the competition, the top three stood on the podium in turn, and then heard the 4WD fighter say, "now let's invite Mr. Jia Yapeng, chairman of Daqian group and founder of Huaxia 4WD, to present the award to the champion, runner up and runner up this time!!"

Chairman of Daqian group!!

Hearing that the identity of the awarding guest was the chairman of Daqian group, all the audience, especially the parents, stared to see who the guy who made the 4WD and sucked his wallet clean.

Unfortunately, because the award is held in the center of the gymnasium, it is not easy to see a person's appearance clearly, and the TV picture only captures Jia Yapeng's side face, and it still seems a little confused.

"Jia, uncle Jia!!!" Liu Nian was a little confused when he saw Jia Yapeng suddenly appear near the award platform. Liu Nian didn't know until the 4WD fighter told Jia Yapeng his identity. This uncle who has been accompanying him and went home with him yesterday is the chairman of Daqian group and the founder of Huaxia 4WD!!

Thinking of this, Liu Nian looked at Jia Yapeng's eyes full of little stars of worship.

He didn't worship Jia Yapeng because he was so rich. At this time, he didn't know how powerful the chairman of Daqian group was economically.

Liu Nian admires Jia Yapeng's identity as the founder of Chinese 4WD. If Liu Nian is a little Taoist, Jia Yapeng is the proper Taoist ancestor in his eyes.
