In 2069, the country's most famous inventor and the most famous invention maniac -- Dr. Bi Tiancai, Dr. Bi Da! Holding the latest type of energy block that he had just spent a huge amount of money to buy, he shouted in ecstasy: "Success, success! With this energy block, I don't have to carry a battery box weighing dozens of kilograms, and I can easily travel further through the era!"

This is another invention maniac just used a piece of extraterrestrial meteorite to refine the new type of energy block, due to the scarcity of raw materials, so this energy block was sold to Bi Tiancai at a price of 600 million yuan, or how to call it an invention maniac? 600 million yuan, Bi Tiancai didn't even hesitate to buy it, the old housekeeper only twitched in his heart, the tens of billions of assets left by Master Bi were squandered by Bi Tiancai in just ten years, and now the old housekeeper doesn't know how long the remaining money can last!

Bi Tiancai doesn't care about this, as long as his invention can succeed, what is it to spend some money! Bi Tiancai rushed to his own laboratory, and now the laboratory where Bi Tiancai is located was built in this remote place ten years ago with a huge amount of money, in order to make it more convenient for experiments, and at the same time to keep it more secret! This place was originally an abandoned reservoir, and there were no people around, and Bi Tiancai was very satisfied with this place.

Sitting in front of the computer, Bi Tiancai tried to set the farthest time to travel, the system showed that it was 71 years after calculation, Bi Tiancai thought about it, and said to himself: "It's 2069, 71 years, that's 1998, it's still too little, alas, no matter what, pass it over first, count how much energy needs to be consumed back and forth, this time you can stay for a while in the past, and feel the life of more than 70 years ago!"

Bi Tiancai is not worried about the safety of the crossing at all, he has successfully crossed several times, if he didn't carry a battery box of dozens of kilograms in his hand, he wouldn't have come back immediately every time he wore it. This time, the new energy block is only the size of a mobile phone and only three millimeters thick, so this time the crossing can be described as extremely easy!

Set the time span of the crossing on the host, then pick up the controller with the emerging energy block installed, enter the fingerprint, confirm the crossing, press the "start" button on the control board, and disappear in the laboratory in an instant!

Successful crossing, Bi Tiancai returned to 71 years ago, but our Dr. Bi Da was very happy and sad, too careless, ignoring the fact that the place he bought for experiments was once a reservoir, 71 years ago there was still water, although the last two crossings were in the same place, but that is, more than ten years ago, of course, there was no problem, but now Dr. Bi Da crossed over in the water, and was stuck between two stones, Bi Dacai was suddenly shocked, struggled desperately, and hurriedly pressed the control board on the " "Return" button, but it didn't make it back in time, oh my!

In this way, a great inventor fell in an abandoned reservoir, and in a flash, it was ten years, and the time entered 2008......
