After nearly twenty days of expansion, two days before the end of the military training, the search process for metal seeds had been completely over, and Chen Chen had finally discovered all the metal seeds on the earth.

It has been determined that the total number of these metal seeds is 1,296.

Most of the metal seeds fall in the sea, and a few on land, about one-fifth of the total number of stations.

The initial drop range of the metal seeds was centered on a narrow strip of land such as the East China Sea and the South China Sea, and spread to the surrounding areas.

Naturally falling seeds, the northernmost one, in the Bering Strait between the easternmost tip of Asia and Alaska.

The southernmost one, in New Zealand, the easternmost one, in Hawaii, and the westernmost one, in the Red Sea.

This huge distribution area accounts for more than one-third of the entire Earth's surface area.

However, this was only their initial drop location, and after the metal seed was cracked and controlled by Chen Chen, they immediately started to act according to Chen Chen's plan.

They set out from the bottom of the sea, through the Red Sea and the Suez Canal, and into the Mediterranean. Some of them remained in the Mediterranean; One part crosses the Strait of Gibraltar and enters the Atlantic Ocean; One part changed shape, climbed onto land, and climbed the Alps.

They went east, crossed the Pacific Ocean, and some remained in the Pacific Ocean; Some landed on the North American continent and climbed over the Rocky Mountains, enveloping the American mainland.

They advanced to the southwest, and some landed on the African continent; One part goes around the Cape of Good Hope and into the Atlantic; Some continued westward to the South American continent and invaded the rainforests of the Amazon.

They passed through the Bering Strait and into the Arctic Ocean.

They traveled all the way south to the continent of Antarctica.

By the time most of the seeds were cracked, 1,000 of them had been evenly distributed across the entire earth under the coordination of the Reflection Crystal.

The pulse network built with metal seeds as nodes has been completely uniform and sufficient, covering every inch of the entire earth.

The pulse signal of each metal seed has an effective radius of more than 1000 kilometers.

However, due to the quantity, each seed order has a radius of 500 kilometers, which makes it possible for any place to accept signals from more than 4 nodes.

Through this network, Chen Chen can keep abreast of all changes in the entire earth at any time.

Even if the entire earth, all the wired and wireless networks of humanity collapse, and they will not be affected in any way.

In the future, if you want to publish your own mobile phone or computer, you can completely stop using the existing network.

No longer pay attention to other network providers, no longer pay attention to any chip manufacturers, no longer pay attention to any communication patents and communication equipment.

You only need to design a chip that can accept pulse network signals and install it in your mobile phone or computer.

You can get almost unlimited network signals anywhere in the world, whether it is a jungle or a high mountain, whether it is the bottom of the sea, or Antarctica.

Today's signal speeds and widths already exceed any wired and wireless network on the planet.

In particular, all nodes of this network are alive and can be upgraded indefinitely, and as long as they continue to be supplemented by iron, they can continue to improve the performance of the network indefinitely.

However, it is used as a network node, which is actually only a subsidiary function of these metal seeds.

Because of their true nature, they are so powerful that a single digit seed growing is enough to crush any discordant force on Earth.

Therefore, Chen Chen let the 1,000 metal seeds be used exclusively as communication network nodes.

After absorbing a certain amount of iron, reaching the size of a human being, gaining a certain self-defense ability, and meeting the signal strength requirements, they will no longer be upgraded and temporarily fixed in the network.

The remaining 296, 160 of which stop after the individual grows to about 1000~3000 tons, are evenly distributed to various densely populated areas on the planet and used as patrols.

Their main task is, first of all, to protect the security of ordinary communication nodes, to prevent them from being destroyed by humans who do not know the truth, or to use them for research.

Then a subsidiary task is to temporarily enhance the strength of the network when Chen Chen wants to focus on monitoring a certain place.

Then there are 60 more, and then grow to about 3000~8000 tons to stop, as the former's enhanced type, to patrol and protect within the continent or ocean.

Then there are 40 more, growing to 8,000~20,000 tons, which are used as patrol and protection teams around the world.

Then there are 20 more, which will be used as Chen Chen's last safe hole cards.

With these 20 seeds, Chen Chen did not limit their growth ceiling, allowing them to use all their resources to develop with all their might.

When they are fully mature, they can be as small as 20,000 tons and as high as 200,000 tons.

Their real purpose is to do so, to stand up to all the armed forces of the entire planet.

Even the strongest nuclear bombardment must be pit intact.

In this way, the total number of seeds that have been used is 1,280.

In the end, the remaining 16 seeds have been discovered by the national forces on the earth and placed in major laboratories, and various experiments are being carried out all the time, and it is not convenient for Chen Chen to control them at will.

Among them, there are 8 on Donghua's side, and Chen Chen has already cracked them, but they still need to stay in the laboratory to do research samples.

Then, because it is within the range of the metal seed landing point, Neon gets 3 metal seeds, South Korea gets 1, the Rakshasa Far East gets 1, and European countries also get 1 through the ocean fleet.

Finally, there is America, because of its strong military power distributed all over the world, and finally got 2 metal seeds.

After discovering the characteristics of metal seeds, researchers and governments in these countries, including Donghua, have made great efforts to carry out scientific research and try to figure out what these seeds are.

And Chen Chen, who has already covered the network all over the world, can crack and control these seeds at any time, and then he can make these seeds become whatever he likes.

But Chen Chen didn't move these 16 seeds for the time being, first of all, it was unnecessary, because he already had more than a thousand of the same things, and he didn't need to care about a dozen at all.

Moreover, it is completely impossible for these earthlings to crack and control the metal seeds, and they can get them at any time if they want, they are just temporarily helping them to keep them.

Moreover, putting them in these countries for the time being, if necessary, can send them the wrong signal through the reaction of the metal seeds.

All in all, if you put it there for the time being, you may be able to use it in the future, but if it is completely cracked, it will only be a dozen more redundant signal nodes, which is completely worth the loss.

However, for these 16 seeds, Chen Chen will not ignore them, especially the 8 in Donghua's hands.

They are now in their own laboratory, claiming that they want to crack them, and by now, they have been tossing for more than 20 days, and it is time to release some concrete results to the public.

So, after waking up the morning after the end of the military training, Chen Chen nestled in his sister's arms, sorted out his thoughts briefly, broke free from his sister's arms, got up and stretched, and was ready to do something serious.
