After personal experience, Ding Yang finally understood the mystery of the lake.

For rare non-living objects, they may temporarily remain in the silt under the lake. However, once the number exceeds a certain limit, it will disappear like snowflakes under the sun.

As for erecting corresponding building fulcrums in the lake water, we can reduce the distance for long-distance raids.

God knows what's going on, but the concrete building just built disappeared in the blink of an eye. No matter how hard it is, it will be scattered like tofu.

After being blocked several times in succession, Ding Yang thought about it and came up with a new plan to operate it.

The current problem is that if you cannot get into the lake water, you can reach the circular black hole in the center of the lake water in the shortest time.

"Hmph, there is no fulcrum on your feet. Can't I fly over! As long as I design a suitable drawing, use the raw materials stored in the storage ring, and the supplies on the lake shore, it's okay to build a small airship. Humph, I won't believe it!"

At first, Ding Yang wanted to build a helicopter and flew over, but unfortunately the design drawings were too complicated. With his IQ, he studied design major, but he didn't know that he would graduate from the year of the Monkey and Horse.

The second choice is to try the glider. The design problem is the same as before, and there is even an additional operational problem.

Not to mention that the glider has high requirements for wind power, his current two-knife technology cannot control the target the glider wants to fly. Even if it can be made, he may not be able to fly above the circular black hole in the center of the lake.

As for the hot air balloon, it is simple, but it is impossible to control the direction at all, so you can only cancel this setting.

The final plan is to build a simple airship to ensure that it can fly over. The structure does not need to be too complicated, and it can simply adjust the direction and ensure that it can fly above the black hole in the center of the lake.

Next, Ding Yang began to recall the airship design drawings he had seen before. He really studied this thing a bit.

I didn't know which Feng I was trying to draw at the beginning, so I was particularly interested in the history of the airship. Not only did I study all the history of the airship, but I also checked various airship design drawings. I even bought a lot of small accessories to make a mini airship.

It was not possible to use that small airship to carry people at the beginning, but it was quite impressive as a toy.

So in the following time, Ding Yang began to try hard to recall his original accumulation. With his unremitting efforts, he actually drew corresponding design drawings. After repeated calculations, he determined that this drawing could be made.

Then we started to collect the corresponding raw materials, and by the time everything was ready, it was already bright.

After a night of integration, Ding Yang was sure that he could complete the small airship. He did not expect to fly far or high. As long as he could take him from the shore to the sky above the black hole in the middle of the lake, it would be enough.

After the spirit was greatly boosted, Ding Yang even forgot to rest. After a little relaxed, he began to get busy again.

With the help of the vow badge, Ding Yang basically built a small airship without long.

Next is an experiment, trying various effects of airships and making corresponding improvements. Ensure that they can fly for a short distance, and then trying to hang in a fixed position for a period of time.

This is how he can stop the airship and land when he flew above the black hole in the middle of the lake.

If you work hard, time passes quickly. Ding Yang doesn't care about fatigue, constantly improves and tries.

Finally another day passed, and after the sun set, the available finished products were basically taken out. Ding Yang even sat on and took off and flew on the lake shore for a while, and the effect was pretty good.

Next, except for the waiting time approaching midnight, there is only one more test to fly to the lake.

According to the test results made on the lake shore during the day, the airship's launching height can reach more than 1,000 meters. The flight time limit of the airship is still uncertain, but the distance from the 800-meter shore to the center of the lake is only a few minutes at most.

However, in order to determine the test, Ding Yang boarded the airship again and prepared to fly the actual route for exercise.

As a result, this exercise was covered with a shadow from the beginning - Ding Yang's operation and steering after boarding the airship was always not as flexible as before. It was much more difficult to change the direction.

It is not difficult to turn to other directions, but the key is that it becomes much more difficult to fly in the direction of the lake.

"Hey, my bad temper, where did this come from?" Ding Yang was really scared, and he already had a bad premonition in his heart: "It would be that I had done useless work this day and one night!"

As a result, the airship finally turned around successfully, but the accident had just flew over the lake, and before it could fly far away.

The airbag above the head lost its floating power for some reason, and even the airbag and airship fell off the lake. This is not Newton's apple, how could it fall down for no reason!

Unfortunately, Ding Yang doesn’t care about pursuing the reason now, so it’s important to ensure his own safety as soon as possible.

If he himself fell into the water of Beihai Lake with the airship, he would probably shrink step by step like the dark clouds of horses yesterday, and finally disappear completely in the lake.

From the crash of the airship to the beginning of falling, the time difference between the airship was very small. The speed of the airship falling was not slow at all. It can be said that it fell from the air in the blink of an eye and fell into the lake water: "Puzzle!"

During this period, Ding Yang held his breath and stared at the lake with all his concentration approaching his eyes little by little.

He grabbed the moment when he was about to fall to the lake and jumped out, stepped on the edge of the airship basket, and flew out with the force.

Before he could land on the shore of the lake from mid-air, the airship had fallen into the lake water as a whole and began to sink.

Fortunately, Ding Yang's airship just now was not able to fly far, and he just passed the lake and moved forward less than ten meters. Otherwise, if the distance was too far, even Ding Yang would not be able to leave the lake without leveraging the force.

This time, I tried my best in mid-air, but I just landed on the shore without touching the lake.

"Be good, good guy!" When a feeling of luck that survived the disaster came to my mind, Ding Yang had just stood firm.

When I looked back at the direction of the lake, I saw the airship slowly sinking with "gurgling" bubbles.

Under Ding Yang's gaze, you can clearly see that the hull and airbag of the airship sink while slowly disappearing after falling into the lake.

In just a few minutes, a huge small airship had completely disappeared into the lake. The lake water was still so clear that it seemed so clean that there was no debris.

"Hiss..." A cool air rose in Ding Yang's heart, which was too terrible.
