After leaving Jia Yapeng's former residence, Donald's mood finally recovered a lot. The two officially began to play in Yuzhang city. The game lasted until the evening. They arrived at the last destination in the plan: Tengwang Pavilion, the landmark ancient building of Yuzhang city.

As one of the three famous buildings in the south of the Yangtze River, Tengwang Pavilion is becoming more and more beautiful. The management department added a full set of neon lights to Tengwang Pavilion, making Tengwang pavilion the brightest and most beautiful one in Yuzhang at night.

However, today's Tengwang Pavilion is somewhat special, because when Donald and Emma arrived here, they found that there were children around Tengwang Pavilion, and almost all the children were carrying a big toolbox. Many children were preparing a car or something on the spot.

"What is this?" Emma asked curiously.

"This is a 4WD!" Donald said with emotion. Unconsciously, he hasn't played a 4WD for seven or eight years. Obviously, this is his favorite toy when he was a child, but he hasn't played for seven or eight years. Obviously, he is only 13 years old now.

"I'll inquire!" Emma talked to the security personnel behind her, and then excitedly ran over to tell Donald, "Donald, it turned out that today is the annual national 4WD tengwangge challenge. All the 4WD masters and players in China, including the Chinese Champions and the world champions in previous years, have come to participate."

"We are lucky to see such an interesting game today!"

"Tengwangge challenge!" Donald's expression moved slightly. He had heard of this competition to commemorate the whole country. However, this is only a separate track of tengwangge, so it can be finished in 20 minutes.

Moreover, 20 minutes is not a too difficult achievement. Simply speaking from the distance, 20 minutes is enough, but the problem is how to ensure that your 4WD car does not get off the track frequently or even break directly within 20 minutes, which is the biggest difficulty.

"OK!" Donald went to the nearby official store without hesitation for a long time. He took out a gold card and brushed it. In the envious eyes of the children around him, he began to report the names of various parts.

It can be seen that Donald has studied the 4WD, and the names of many parts are very professional, which Emma has never heard of. Finally, Donald paid more than 5000 dollars to buy these parts, and then spelled out a 4WD on the spot in the envious eyes of the surrounding children.

Because there are a large number of 4WD enthusiasts at home and abroad, many foreign 4WD players will come to the competition every year, especially Fusang people.

In those years, Fusang's 4WD car players suffered a disastrous defeat in this competition, which made Fusang hand over the title of the world's No. 1 4WD car player to Huaxia, which made many Fusang people resent it. Therefore, it was Fusang's biggest dream to win again in the tengwangge challenge and regain the honor belonging to Fusang.

Unfortunately, due to the terrible population base in China and the continuous 4WD championship, the 4WD masters in China have far surpassed Fusang and reached the point of seeking defeat alone. Fusang people have never had a chance to win the championship of this challenge, and even it is very difficult to enter the top three.

However, thanks to these Fusang people, the organizers of the event did not require to sign up with ID cards, and so did foreigners with passports. Therefore, Donald successfully signed up and boarded the stadium with his newly assembled 4WD car.

This time, there are 30 tracks in the initial stage, and six groups of tracks are side by side, so that a large number of players participating in the preliminary can not wait. As long as the registration is completed, they can start instantly and complete the preliminary stage quickly.

A large number of players came to the competition this time. There were seven or eight players competing with Donald. They each selected a track. As the starting gun rang, all 4WD cars rushed out at the same time.

Because there are a large number of racing cars participating at the same time and it is race time all day, there is no special referee to observe each player. The organizer uses the latest network technology and intelligent recognition technology to install a camera every 20 meters or so in the track, and then uses this camera to record all racing cars passing through the camera position.

Such a camera is called a checkpoint.

These 4WD cars can only get the final results by passing all the checkpoint records. If one checkpoint is missed, the game will fail, which can prevent cheating to a considerable extent.

It's a little pity that Donald's 4WD is temporarily assembled and not a well-designed car, so although it is installed with expensive parts.

However, after starting, it seems that there is some cooperation. The 4WD fell behind as soon as it started. Finally, when the 4WD rushed into the entrance of tengwangge, Donald's 4WD was more than ten meters behind.
