Emperor Ming's grandson

Chapter 25 Our eldest grandson really has a solution!

The properties of objects mainly include mass, volume, shape, density, hardness, color, and temperature. Mass is equal to the product of density and volume. Now that the volume is limited, it is equivalent to only studying density. Because other hardness, The probability that object attributes such as color and temperature affect the transmission of items is obviously smaller than the more stable attributes of density and mass.

The tree chosen by Zhu Xiongying is also the same kind of tree, namely Macaranga tanarius. Macaranga tanarius is a tree of the genus Macaranga in the Euphorbiaceae family. It is named after the sap secreted from the broken branches of its branches turns blood red when oxidized by the air.

Macaranga tanarius grows to a height of more than ten meters and is often found on islands or coastal low mountain shrubs or secondary forests. It is one of the most common trees on southeastern coastal islands.

Therefore, the density of Macaranga tanarius must be basically the same, and the only variable that affects the time regression of new and old Macaranga tanarius branches is the growth time.

When the density of the old and new Macaranga tanarius branches is the same, the experimental result is that the older Macaranga tanarius branches can be transmitted to the Ming Dynasty world and become newer, but the newer Macaranga tanarius branches cannot be transmitted to the Ming Dynasty world.

Zhu Xiongying took branches from other trees and came to the same conclusion.

This shows that for items with the same density, the time-tracing effect on the items should be the same, so the old ones become new and the new ones disappear directly.

Even the branches of old Macaranga truncatula and other trees should only have a few decades of growth time at most. Therefore, the time of the wood can be traced back to a relatively vague range of several decades.

Soon, Zhu Xiongying had tested everything he could find.

According to the feedback from the other end, as long as the cross-section of these things is smaller than the cross-section of the mysterious vortex, most of them can be successfully transmitted to the Ming world through the mysterious vortex.

As for things like bricks and stones, it is difficult to detect how much the time-traveling effect works on them, especially stones.

But it is obvious that for trees grown at different times, the impact of time retrospection on them is obvious.

Then, Zhu Xiongying went to the beach to pick up some shells and seaweed. To his surprise, none of the shells could be transmitted.

This gave Zhu Xiongying some guesses about the rules of mysterious vortex transmission items.

First, in terms of density.

Capsule＜Twig＜Shell＜Brick＜Stone
While pills can only go back a few years, tree branches can go back decades. The shells have not been tested to determine the specific time back range. The bricks were found from the ruins of a building built in the last century and are visually estimated to be seventy years old. , Stone cannot verify the effect of time retrieval at all, because stone may not change for hundreds or thousands of years.

Therefore, Zhu Xiongying speculated that the rules for the mysterious vortex to transport items are likely to be related to the density of the items.

If this hypothesis is true, it can explain why shells cannot be transmitted because shells are denser and have a shorter life cycle. Even if they die and become shells, they will be affected by corrosion such as weathering. Similarly It didn't exist for long, so the shells he picked up from the beach were thrown into the mysterious whirlpool. The time could go back several decades, and then they would disappear directly and would not be transmitted to the Ming Dynasty world at all.

So Zhu Xiongying temporarily came to a conclusion that seemed quite reliable.

——The smaller the density of the object, the smaller the effect of the time retroactive effect; the greater the density of the object, the greater the effect of the time retroactive effect.

However, there are still some things that cannot be explained.

First, why are there always some items that can be transferred according to this rule, but cannot be transferred in the end?

Zhu Xiongying's guess is that the mysterious vortex may be damaged due to swallowing and other factors during the process of transporting items, or it may not be 100% successful in transmission, and some "tolls" must be paid.

Second, since the density of objects has an impact on time retrieval, what about mass? Is there a transmission upper limit for the total mass of an object? After all, although the cross-section of the mysterious vortex is fixed, the length is not known. If there are no restrictions, it can theoretically even be sent across thousands of kilometers of railway tracks.

In response to this, Zhu Xiongying made another attempt, that is, he moved two long stones and threw them in.

Although these long stones don't look wide, they are long, but they are not light in weight. If you really don't have any strength, it will be difficult to even lift them, let alone carry them.

Fortunately, Zhu Xiongying paid great attention to physical exercise. He managed to drag it to the grave, then raised it high and threw it in like a javelin. However it was not successful.

This also gave Zhu Xiongying another conjecture, that is, the cross-section of the mysterious vortex limits the volume of the transported object, and at the same time, the "infinitely long" method cannot be used to increase the mass of the transported object as much as possible.

In other words, the mysterious vortex directly limits the cross-section of the transmitted object. Once it hits the edge, it will directly produce an "annihilation" effect. In fact, it also limits the overall quality of the transmitted object.

Therefore, as an object of the same density, you can throw a branch, but you cannot throw the trunk, because when the cross-section is limited, the longer the object, the greater the mass.

Zhu Xiongying clearly observed that the cross-section of the mysterious vortex was getting larger each time.

So can we also guess that as the cross-section of the mysterious vortex expands, the limit on the mass of objects that can pass through it will gradually be relaxed?

Zhu Xiongying wrote down three conjectures tested through experiments on his mobile phone memo.

①The law of time retracement of objects is that the smaller the density of the object, the smaller the effect of time retracement, and vice versa.

② Even if the transmission conditions are met, the current object still has unexplained losses during the transmission process.

③The mysterious vortex will expand over time, and the limit on the mass of the transmitted object will also expand.

"yeah!"

Zhu Xiongying waved his fist vigorously.

He finally roughly understood the principle of the mysterious vortex's transmission of objects.

After this test, Zhu Xiongying has determined that his idea should be feasible.

So, Zhu Xiongying said to the mysterious whirlpool: "Grandpa, it shouldn't be a problem to solve the air seal, but it will take some time for me to find communication items that can solve the air seal."

------

Zhongshan.

Hearing this answer, Zhu Yuanzhang was very satisfied.

Our eldest grandson really has a solution!

But at this time, Zhu Biao suddenly said thoughtfully: "Father, if there really is something on Ying'er's end that can solve long-distance communication."

Zhu Yuanzhang looked at his son, a hint of surprise flashed in his eyes, and he thought of many things in an instant.

If there is such an artifact, then the communication and connections throughout the Ming Dynasty will be greatly strengthened!
That means that the problem that the imperial power could not reach the local area in time that troubled him before will be easily solved by Da Sun!

At this moment, Zhu Yuanzhang couldn't help but look forward to it.

It's not that he can't afford to kill in a big way, but the artifact that Dasun is about to send is more cost-effective.
