"Miracle! Everyone, this is a miracle! Evangelion's speed in the water is much faster than the other cars! He's catching up to his opponents! "
"He's catching up! Evangelion has already caught up to the fire hydrant! He'll soon catch up to Pegasus!"
"Evangelion has now jumped to fourth place. The three cars in front of him have to be careful. There's only 200 meters left to the finish line. Can Evangelion break out of the encirclement and change his fate?"
"Super! He passed! In the last 50 meters, Evangelion overtook I Want Song Jiang and is now in second place. But it looks like it'll be very difficult for him to overtake the first place Whirlwind because he's only 10 meters away from the finish line. There's basically no suspense about the championship anymore! "
"No, my God! Whirlwind's speed is rapidly slowing down! He's stopped! It looks like there's a problem with Whirlwind's engine. It looks like our championship is about to undergo a dramatic change … Let's congratulate Evangelion for completing a shocking reversal! He's become our champion! "
"Evangelion is the champion!"
The 4WD Fighter finally shouted these words in a hoarse voice. Liu Nian looked at his car in disbelief. He originally thought that he would at most get into the top 10. He didn't expect to stand on the podium of the championship in the end.
At this time, the entire stadium was filled with cheers. No one liked to watch a competition that went smoothly. Only the kind of competition where one won the championship in the face of adversity and made an earth-shattering reversal was the kind of competition that the audience loved to watch and talk about.
Today's match was a stunning reversal of fortune. After suffering from the worst start, Evangelion managed to turn the tables with amazing underwater speed and clinch the championship. This caused the audience to go wild with cheers and shouts.
The other contestants looked at Liu Nian curiously. They couldn't understand how an Evangelion could be so fast underwater. It didn't make any sense at all.
"Contestant Liu Nian, can you share with everyone the secret of your mini 4WD car?" The 4WD Fighter put the microphone in Liu Nian's mouth and asked curiously.
"It's probably because my mini 4WD car is heavier!" Liu Nian thought for a while, then said, "Also, I modified the 4WD's shell at the last minute. That should have something to do with it!"
Liu Nian said. In front of the camera, he took off the hood of his car. Upon closer inspection, it was discovered that Liu Nian's car had indeed undergone an emergency modification. He actually directly cut off more than half of the car's hood, leaving only a curved hood. He also removed the entire rear wing. In the end, the hood could only barely cover the car.
"This is the most suitable shape for underwater operations!" Liu Nian took the car shell and explained, "This model doesn't have anything extra to create resistance. It can minimize the water resistance. It involves some simple fluid mechanics. Specifically …"
Liu Nian explained a lot of knowledge about fluid mechanics into the microphone, and the audience was dumbfounded as they listened.
"Uh, contestant Liu Nian, you just said that your vehicle is heavier than the others. Why is that?" the Four-wheel Drive Fighter hurriedly changed the topic.
"Because my car's engine can't be waterproof, so I can only use some other means!" Liu Nian stuck out his tongue and said. Then, in front of the camera, he skillfully opened the back cover of the engine. Only then did everyone realize that the entire back cover was filled with a large pile of yellow stuff. The entire back cover was stuffed to the brim.
"This is … lubricant?" the Four-wheel Drive Fighter said in surprise after smelling it.
"Yes, this is a lubricant that is insoluble in water. At the same time, lubricant is also non-conductive. I think that as long as I fill the entire rear engine room with lubricant, water can't enter the rear engine room. At the same time, lubricant itself is non-conductive, so it won't affect the normal operation of the engine, let alone the output of the engine!"
"In addition, I also applied lubricant to the contact area between the battery and the metal plate. The entire battery compartment was also covered with a large amount of lubricant, and wrapped with a circle of tape to ensure that the lubricant won't leak. In this way, the output of the engine can be maximized!"
"But because I used so much lubricant, the speed of the engine will definitely be affected. In addition, the weight of the car is seriously excessive, so the speed of the track is a little slow at the beginning!"
"Fortunately, the competition venue can provide unlimited lubricant for us to modify the 4WD, otherwise I wouldn't have been able to get so much lubricant!" Liu Nian said in a low voice, as if he was afraid that because he used too much lubricant, the officials would come looking for him to pay compensation.
"Lubricant, this guy …" Jia Yapeng was dumbfounded. Using a large amount of lubricant to make the 4WD engine waterproof … Jia Yapeng suddenly felt that he should find this little guy to be the screenwriter of "Four-wheel Drive Brothers". Such a fancy operation, Jia Yapeng himself couldn't think of it!
[PS: Lubricant waterproofing is a fancy operation that a friend of mine brought up when they were talking about 4WD cars. It has never been verified, and is completely nonsense by the author. Please don't try it in reality, or else you'll have to bear the consequences.]
"Then why did the speed become faster after the weight increased?" the Four-wheel Drive Fighter asked after thinking for a while.
"I think it's probably because the heavier 4WD cars have a stronger grip underwater!" The little guy said after thinking for a while. "It's very easy for the 4WD cars to slip underwater. The faster the motor, the easier it is to slip. On the other hand, the heavier 4WD cars are able to hold on tightly to the ground.
"In addition, when driving underwater, the torque provided by the engine is more important than the speed. It's like when you're going up a hill, a racing car with a high speed will have a hard time. Only a racing car with a high torque will be able to easily climb up hill after hill!
"Driving underwater is the same as climbing up a hill. You'll have to bear a lot of resistance to move forward. That's why I made some adjustments to the engine. I rewound the coil, adjusted the torque of the engine to the maximum, and lowered the speed of the engine. This is also an important reason! “
Liu Nian didn't hide anything. He explained all the modifications he had made to the 4WD car. At the same time, the surrounding contestants and audience were enlightened, and at the same time, they were sincerely convinced by him.
All the modifications were done by him personally. He was even able to rewind the coil to change the operation of the engine. Liu Nian truly deserved this championship!

With the end of the competition, the top three contestants stood on the podium in order. Then, they heard the Four-wheel Drive Fighter say, "Next, let's welcome the chairman of the Daqian Group, the founder of Hua Xia's 4WD, Mr. Jia Yapeng, to present the first, second, and third place prizes!"
The chairman of the Daqian Group!!
When they heard that the guest presenter was actually the chairman of the Daqian Group, all the audience, especially the parents, widened their eyes. They wanted to see who the guy who had made the 4WD car and sucked their wallets clean was.
Unfortunately, because the award ceremony was held in the center of the stadium, it wasn't easy to see a person's appearance clearly. Moreover, the TV screen only captured the side of Jia Yapeng's face, and it looked a little blurry.
"Uncle, Uncle Jia!!!" When he saw Jia Yapeng suddenly appear near the podium, Liu Nian was a little confused. It wasn't until the Four-wheel Drive Fighter said Jia Yapeng's identity that Liu Nian realized that the uncle who had been accompanying him and went home with him yesterday was actually the chairman of the Daqian Group, and the founder of Hua Xia's 4WD!!
Thinking of this, Liu Nian looked at Jia Yapeng with eyes full of little stars of worship.
He didn't worship Jia Yapeng because of how rich Jia Yapeng was. At this time, he still didn't know how powerful the chairman of the Daqian Group was in the economic field.
What Liu Nian admired more was Jia Yapeng's identity as the founder of Hua Xia's 4WD. If Liu Nian was a little Daoist, then in his eyes, Jia Yapeng was a proper Daoist.
