"All the planet's trade is quota trade. Xie Shangjun glanced at Gu Hanhan, "Do you understand the meaning of the quota, Hanhan?"

"Quota trade means that the amount of resources that can be sold on the earth every year is a fixed amount, and this amount will be distributed proportionally to each country, the region, the Covenant free trade body, and so on. That is to say, the amount and proportion of the earth's resources that each country, every celestial region, even every galaxy, and every planet buy every year are determined, and this is its quota. ”

"On the earth's side, the total amount of resources that should be exported each year is announced by the Earth National Resources Committee, together with the two scientific committees, the trade and commerce guilds, and other relevant departments, at the end of each year the types and quantities of the earth's resources exported in the following year. The trading enterprises that are members of the Earth Trade and Commerce Guild apply for the export sales right of the relevant share of export resources in the guild according to the number of agents owned and planned to be established in their own trade network and trade lines, which is the first quota of Earth Trade, the sales quota. ”

"In the space dimension, the Conference of the States Parties to the Convention on Reserves of the Earth meets every five years, at which the percentage of purchases to which each country is entitled, negotiated and distributed, and is determined by the conclusion of a treaty. The countries participating in the allocation can only be sovereign states and sovereign planets or planet associations joined by the Free Star Alliance, and each allocation is valid for five years, and must be purchased according to the quota signed by the treaty within five years. If a newly established State requested to participate in the allocation or objected to the established quotas, it would have to be re-amended at the next Meeting of States Parties five years later. This is the second quota in the Earth trade, the purchase of quotas. ”

"To be a local product company, on the surface, it is very simple, it is to deal with these two quotas. But in fact, it is far from being so simple, but very complex, and the key to the complexity lies in the earth trade line, and there is a earth trade line sandwiched between the two quotas. ”

"The capacity of the solar system is limited, and due to the limitations of the Earth Reservation Convention and the need for the United Nations to combat the trade of black ships, all the Earth trade in the universe is sold at the port. That is to say, in principle, the resources within the quota sold should be transported out of the earth by the earth trading company from the earth and then arrive at the trading place before they can accept orders for sale. Anyone who dares to take a risk and trade in this way of self-pickup will have their trading license revoked, their license revoked, and a fine will be imposed on the seller's Earth Trading Company. Both buyers and transporters are treated as pirates and are resolutely combated. ”

Therefore, when conducting space trade, earth and pharmaceutical companies and local product trading companies usually use the form of setting up trade points in the universe and sending foreign representatives to carry out this kind of mandatory quota to the port trade. The trade points that are close to each other are connected into a line, which is a fixed trade route and a shipping route, which is the earth trade route of the universe. Two or more trade routes with overlapping points and routes are known as the Earth Trade Network. ”

"Since the earth's trade route is a trade route, it must rely on the subspace shipping lane. But it is different from the subspace shipping lanes - the earth's trade routes are far smaller, narrower, and shorter than the subspace ones, and the distribution of agents for cargo ships on the trade routes is even more scarce, far from being compared with space hops. ”

With a wave of Xie Shangjun's right hand holding the ring, the mirror image of the Milky Way was projected in front of their eyes. Immediately afterwards, countless shining points of light stood out in the mirror, identifying a galaxy, a star field, a celestial region, and some thick rays of light connected in circles and rows to form an asymmetrical three-dimensional spider web. The center of gravity of the spider web is obviously tilted towards the Milky Way side in the direction of the Earth, and the central planet is marked by an extremely bright diamond-shaped block, which is the lighthouse star in the center of the universe.

Taking the lighthouse star as the origin, the cobwebs are ringed and spread out one by one, and in general, the closer to the lighthouse star, the tighter it is, and the farther away from the lighthouse star, the more sparse it is, and the distance between the rays ranges from hundreds of light-years to thousands of light-years before being assigned to one. However, locally, the cobwebs of light show an imbalance in distribution, in some places the distribution of the light web is much denser than the surroundings, and in some places it is sparser than the surroundings, spreading out throughout the cobweb, showing a patch of light and dark mottled, as if it is an old costume that has been bitten by insects and rats.

"Look, this is the backbone network of the subspace channel," Xie Shangjun pointed to the three-dimensional optical network on the mirror and said, "With the lighthouse star as the center, connect all the important planets, galaxies and galaxies of the galaxy. Even if the galaxy is the most remote, backward, sparsely populated, and barren space in the galaxy, at least there will be a main jump point on this trunk road, as a port to connect with the entire galaxy, so as to avoid the situation and possibility of being far away from the mainstream human society and civilization for a long time, and the entire universe will be desertified, discrete, and eventually completely degraded or even lost. ”

Xie Shangjun waved his hand again, and one of the subspace trunk channels of the optical network was infinitely magnified. In the universe around this short arterial road, many new points of light have been re-lit, and they also mark various galaxies, star fields, national port stars, etc., from the main jump point of this subspace arterial road, like branches, many smaller light whiskers stretch out, criss-crossing, branches, and spreading. The trunk road shrank back into the projection mirror, and all the jump points on the entire subspace backbone network stretched out such branches, densely paving the mirror image of almost the entire galaxy, but it was still denser the closer to the beacon star, the farther away from the beacon star, the more sparse, and some places were brighter. Some places are dark and mottled.

"This is a feeder network of subspace routes, and according to the principles and standards of the United Nations Routes Committee, it should be the star fields and places in the universe that you have heard of, and it can be connected. Xie Shangjun continued, "There are also subspace third-level and fourth-level channels under the branch line...... At most, it can go up to level seven, and the cosmic environment around the secondary channel galaxy can meet the minimum requirements for jump jumps to level seven channel, and the worse environment cannot build and connect to subspace. Of course, the pirate black merchants and other private waterways and secretly built jump points are not included in this list, they don't even have a level at all, they are all built privately. It is said that as long as there are human inhabited galaxies in the Milky Way, there will be a tentacle of a subspace channel that stretches out for connection, and is equipped with at least one jump point, even if this connection channel and jump point are so narrow that they can only accommodate a single leap of one ship at a time. But you also know how unreliable it is to say that 'it is said' that it is not good. Even in the core area of the Milky Way within 10,000 light-years of the lighthouse, there are still a large number of gray and black areas with low or no brightness of heading lights and skynet lights. Anyway, the Route Committee said that it was already fully covered, so let's just say that it was full coverage. ”

"That's not the case with our planetary trade routes—"

Xie Shangjun twisted on the ring, and the mirror image of the galaxy projection was on the side, from the main road to the branch line to the various secondary routes. The entire subspace channel network gradually darkened and blurred, becoming a background vein inlaid in the galaxy mirror. Instead, some bright red and eye-catching points of light appear in the picture, lit up one by one, and then connected into red lines.

The thirteen red threads that appear first, all of them connect to the Earth at one end, and scatter at the other end, radiating in all directions of the Milky Way. Each of them almost coincides with the trajectory of a major subspace road, and extends to the end of the universe, like an iron skewer that pierces the galaxy and puts the starry sky on a barbecue grill. Xie Shangjun pointed to these red lines and said: "This is the earliest earth trade route of the Milky Way, from the earth to the end of the universe, a total of thirteen,"

"It is said that two or three thousand years ago, there were countless branch lines that could trade to every planet connected by the subspace shipping lane, but I believe that it was probably just a legend, and there are only these thirteen ancient earth trade routes that can be examined at present. And since the center of the universe moved from Trajan to the Beacon with the United Nations more than a thousand years ago, these thirteen trade routes have basically declined. Although there are still trading companies' ships walking, and the stationing points and agencies along the way have not all been withdrawn, there are some trading companies with a long history and more nostalgic complexes will still do these trade routes, but the actual amount of goods passing through them is very small, and the trade points should be less than 100, probably adding up to only 12% of the total share of the Galaxy trade in native products, and 8% of the total share of the drug trade. We usually refer to these surviving remnants of the Earth's trade routes as paleotrade routes. ”

As Xie Shangjun explained, the light points connected by the red line continued to decrease, the light of the red line gradually weakened, and the length was also greatly shortened to varying degrees, the longest one was also shortened to about half the radius of the Milky Way, and the shortest one even came to an abrupt end less than 20,000 light-years away from the earth. Immediately afterwards, a thick and long red line appeared on the main subspace road from the earth to the lighthouse star, and the red line represented the light points of the trade points densely, and each trade point protruded in all directions with a few spike-like red lines, some longer, some shorter, but not long, only hundreds of thousands of light years away, three or two trade points. The thick red line is connected to the beacon star, and then with the beacon star as the center, dozens of red lines radiate out in all directions, long or short, thick or thin, some of which represent the red line of the trade channel is extremely long, which can pierce all the way to the end of the galaxy, almost piercing the border, and some are extremely short, leaving the beacon star for thousands of light years before ending in a hurry. From a distance, it looks like a hideous mace, on top of which is a giant sea urchin with crooked melons and cracked dates.

Gu Hanhan noticed that these red lines are basically on the backbone network of subspace, which is a part of it, and occasionally some will extend to branch routes, but there are none that will continue to extend to secondary routes.

"This is the bulk of our current planetary trade routes. Xie Shangjun said.
