After experiencing it himself, Ding Yang finally understood the mystery of the lake.

Scarce non-living objects may be temporarily left in the silt beneath the lake. But once the number reaches a certain limit, it disappears like a snowflake under the sun.

As for erecting corresponding building fulcrums in the lake water, as a way to reduce the distance of long-distance travel.

God knows how, and the work of the newly built concrete building is gone in the blink of an eye. No matter how hard it is, it will be scattered into ashes like tofu dregs after it is built.

After being blocked several roads one after another, Ding Yang thought about it and came up with a new plan to operate.

The problem is to reach the circular black hole in the center of the lake in the shortest possible time without touching the lake.

"Hmph, the fulcrum of the lower foot is gone, can't Lao Tzu fly over! As long as you design the right drawings, use the raw materials stored in the storage ring, and add the materials on the shore of the lake, it is still no problem to build a small airship. Hmph, I don't believe it! ”

At first, Ding Yang wanted to build a helicopter to fly over, but unfortunately the design drawings were too complicated. With his IQ, he went to study design, but he didn't know that he would graduate in the Year of the Monkey.

The second choice was to try the glider, but the design problem was still the same as before, and there was even another operational problem.

Not to mention the high requirements of the glider for wind power, with his current two-knife technology, he can't control the target that the glider wants to fly. Even if he could, he might 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 has no way to control the direction at all, so it can only cancel this setting.

The final plan was to build a simple airship to ensure that it could fly over. The architecture does not need to be too complicated, and the direction can be easily adjusted, so as to ensure that it can fly above the black hole in the center of the lake.

The next thing is that Ding Yang began to recall the design drawings of the airship that he had seen before, and he really studied this thing.

At the beginning, I didn't know what kind of wind it was, but I was particularly interested in the history of airships. Not only did I study all the history of the airship, but I also consulted various airship design drawings. I even bought a lot of small accessories to make a miniature airship.

At the beginning, the small airship was not good for carrying people, but it was still quite impressive as a toy.

So in the ensuing time, Ding Yang began to try to recall the original accumulation. With his unremitting efforts, he really drew the corresponding design drawings. After much deliberation, he determined that the drawing could be manufactured.

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

And after a night of integration, Ding Yang was sure that he could complete this small airship. Don't expect how far you can fly, and don't ask how high you can fly. As long as you can take him from the shore to the sky above the black hole in the middle of the lake, it will be enough.

After refreshing, Ding Yang even forgot to rest, and began to be busy again after relieving his spirit a little.

With the help of the Wish Power Badge, it didn't take long for Ding Yang to basically build a small airship.

The next step is experimentation, experimenting with the effects of airships and improving them accordingly. Make sure you're able to fly short distances, then try to stay in the air in a fixed position for a while.

This way, when he flew above the black hole in the middle of the lake, he had time to stop the airship and land.

Keep working hard, time flies. And Ding Yang didn't care about fatigue, constantly improving, and constantly trying.

Finally, another day passed, and the finished product was basically available after the sun had set. Ding Yang even sat on it and flew on the shore of the lake for a while, and the effect was not bad.

In addition to waiting for midnight, there was only one more test left to fly to the lake.

According to the results of tests conducted on the shore of the lake during the day, the airship can reach an altitude of thousands of meters. The limit of the airship's flight time is still uncertain, but the 8oo meter distance from the shore of the lake 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 actually fly a line to practice.

As a result, from the very beginning of this exercise, a shadow had already been cast over -- after Ding Yang boarded the airship, he was always less dexterous than before. It's a lot more difficult to turn around.

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

"Hey, I'm so grumpy, where did this evil come from!" Ding Yang was really a little scared, and he already had a bad premonition in his heart: "Could it be that this day and night made me do useless work again!" ”

As a result, it finally succeeded in turning around, and as a result, the airship had just flown over the lake, and it had not yet gone far before it had an accident.

The airship airbag overhead lost its airborne power for some reason, and even the airbag with the airship fell off the lake. This is not Newton's apple, how can it fall for no reason!

It's a pity that Ding Yang can't care about investigating the reason now, and it is important to ensure his own safety as soon as possible.

In case he himself fell into the water of Beihai Lake with the airship, it is estimated that he will shrink step by step like yesterday's horse clouds, and finally disappear completely in the lake.

From the wreck of the airship to the start of the fall, the time difference in between is very small. And the airship fell not slowly at all, it can be said that it fell from the air into the lake in the blink of an eye: "Poof! ”

Ding Yang could be said to be holding his breath during this period, staring at the lake with full attention, approaching his eyes little by little.

seized the moment when he was about to fall to the surface of the lake, jumped out, stepped on the edge of the airship basket, and shot out with his strength.

Before he could land on the shore of the lake from mid-air, the airship had already fallen into the lake water in its entirety and began to sink.

Fortunately, Ding Yang's airship just now was not able to fly far, and it was just over the lake and less than ten meters forward. Otherwise, if the distance is too far, even Ding Yang will not be able to leave the lake without borrowing strength.

This time, he tried his best in mid-air, but he just landed on the shore and didn't touch the lake.

"Good boy, good fellow!" When a feeling of luck that was immortal came to his mind, Ding Yang had just gained a firm foothold.

When I turned around and looked in the direction of the lake, I saw that the airship was slowly sinking with bubbles.

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

In just a few minutes, a large small airship had completely disappeared into the lake. And the lake water is still so clear that it seems to be so clean that there is no debris.

"Sizzle......" A cold air instantly rose in Ding Yang's heart, which was too terrifying
