Construction

The second circle has a radius of 20 meters and is not a completely enclosed space. Yichen plans to build a 2-meter-high wall around this circle and then set up Defense Barrier on the wall.

The circular area between the first and second circles is the living area for Yichen and his companions. Normally, caravans are not allowed to enter, but during wartime, caravans are permitted to enter the living area for shelter after inspection.

The third circle has a radius of approximately 100 meters. Yichen selected dozens of points on this circle and used these points to set up a barrier that expands perception. This barrier has no defensive or offensive function; its only purpose is perception.

The ring area between the third circle and the second circle is also the caravan's activity area. There are signs on the outermost edge of this area indicating that ninjas from other countries are not allowed to enter.

There are three passages outside these three circles, Yichen will set up traps in the areas beyond these passages. Of course, these are open defenses, Yichen will inform all caravans not to enter these areas.

However, building Supply Station doesn't require too many ninjas. Yichen arranged shifts at the Supply Station before construction even began. Yichen's arrangement was that after escorting the caravan back to the Land of Earth, there would be a period of free time before the caravan set off again, which would be everyone's vacation.

However, some caravans were far from Iwagakure, so the escort teams didn't get a break. Yichen could only arrange for everyone to pick up caravans that were closer to the village from time to time.

In addition, Yichen pioneered trade routes, and the routes taken were predetermined by Yichen. Therefore, most caravans followed similar routes, and it was not necessary for each caravan to have its own squad. As a result, Yichen's Chunin squad were mostly free, allowing him to arrange extra rest time.

After the shift change was arranged, six teams immediately returned to the village to rest. After resting for different periods, they would return to the Supply Station one after another to replace the teams that were carrying out the mission.

The reason why six teams will return is that the caravans are currently all in the Land of Rain, and there is no need for so many people to carry out missions in the short term.

Then Yichen contacted the two nearby outposts. According to the rules of Iwagakure, both sides are of the same rank and must provide support when one side needs help. Therefore, Yichen needed to contact the outposts as soon as possible, both for safety and to avoid disputes during future missions.

After dealing with these matters, Yichen began the construction of the Supply Station. The construction of the Supply Station started from outside. The Logistics Department personnel who had transported supplies earlier had already returned with the six squads that went back to the village. Yichen could only command his own Team 7 members and the remaining four Chunin squad.

These four Chunin squad include the Meikou Team, the Shinohara Team, a team specializing in setting up traps, and a team led by Medical Chunin. The Chunin specializing Chunin setting up traps is named Inagaki Goichi. Qingtian Yichen the idea of setting up traps on the outside and asked them to think about how to set them up.

Then Yichen arranged for the remaining people to build the directional markers for the third ring and the walls for the second ring. Yichen himself needed to spend his time on the Sensory Barrier for the third ring and the Defense Barrier for the walls of the second ring.

As for the innermost core building, Yichen wasn't in a hurry. He would only build it after the walls were erected. After all, this core building was a secret even to the caravan, and Yichen didn't want outsiders to know its layout.

However, such a large Supply Station cannot be built in a day or two. Yichen and the others mainly focus their energy on cultivation, and only do some construction in their spare time. Yichen felt satisfied if it took half a year to complete the Supply Station.

The next morning, as usual, Yichen first underwent physical training and practiced B-rank Sword Technique, and then sought out Meikou to inquire about Fire Release cultivation.

Meikou had only recently grasped the Nature Transformation of Fire Release, and due to insufficient contributions, he had not yet exchanged for Fire Style Ninjutsu. Therefore, his understanding of Fire Release was not very thorough, but this was for the better, as their understandings were similar, making communication smoother. Meikou Yichen his understanding of the characteristics of Fire Release while practicing.

Yichen listened attentively and pondered the words, occasionally asking questions. The exchange between the two was quite effective, and both gained something, with Meikou seemingly gaining even more than Yichen. Yichen's ingenious ideas gave Meikou moments of sudden enlightenment, and Meikou felt that after a morning of conversation, his understanding of the Fire Release had deepened considerably.

This can be seen from his progress in practicing Fire Release. What was originally expected to take several days to make some progress in Fire Release took shape in just one morning.

Yichen felt a pang of envy as he watched Meikou spit out a mini fireball the size of a basketball.

However, Yichen also gained a lot. Yichen is currently at the border and dares not expend Chakra to practice Fire Release. Originally, he would not have been able to cultivate it and could only slowly increase his understanding. But under Meikou's guidance, and seeing Meikou improve little by little, Yichen's understanding of Fire Release has also improved a lot.

Now, the Fire Release Chakra within Yichen's body has become much more active, with more Fire Release breaking free from its original balance. Therefore, after a morning, Yichen was already able to use his original Chakra to spit out a few Fire Star.

Yichen was excited to see the progress he was making and decided to continue practicing tomorrow.

Everyone practiced all morning. In the afternoon, they took some time to build. Although it was a short time, the ninjas' work efficiency was far superior to that of ordinary people, and the Supply Station slowly began to take shape.

These training days usually pass quickly. A few days later, the first caravan returned from the Land of Rain. This caravan did not venture deep into the Land of Rain, but only traded near the border. After sensing that everything was alright, Yichen Shinohara to escort them, and then paid no further attention.

Over the next few days, seven or eight more caravans returned. Yichen also dispatched Meikou, Inagaki Goichi, and the Medical Chunin Hosokawa's team. Fortunately, these caravans were generally heading in the same direction, so it wasn't necessary to send a team to escort each caravan.

This leaves only the Team 7 at the Supply Station. If another caravan returns before the squad that went back to the village for leave has returned, Yichen will have to arrange for the caravan to stay at the Supply Station for a while.

Fortunately, the teams that had been on leave from the village began to return one after another, the trade route missions gradually got back on track, Yichen's life became more regular. Now, Yichen's activity area is basically around the Supply Station. Except for training nearby, Yichen generally does not leave the Supply Station.

Meanwhile, the Akatsuki Organization in the Land of Rain was also on track in opening up trade routes. Perhaps due to the strong support of the Akatsuki Organization, the Akatsuki had at least twice as many ninja escorting the trade routes as Yichen's side. Yichen guessed that the Daimyo might have really gained a lot from it.

The trade route matters can proceed as planned; there's not much left for Yichen to intervene in. It's time to carry out another mission. In addition to accepting the tasks of opening up trade routes and building Supply Station, Yichen also has the mission of taking over intelligence on the Land of Rain and causing trouble for Konoha.

Yichen couldn't leave the Supply Station casually, so he arranged for Fu to secretly travel to the Land of Rain and make contact with intelligence personnel throughout the Land of Rain.

However, the information brought back by Fu was not of much value. Yichen could guess what these people knew from the original plot.

Since there was no movement, Yichen was not in a hurry and waited patiently at the border, only periodically sending talismans into the Land of Rain to collect intelligence.

Yichen never expected that this wait would last for two years.

Two years have passed, Supply Station has long been completed. Now, the trade route between the two countries of Yu and Tu has spread throughout the entire Ninja World. Only now do people realize that trade can flourish to this extent after tariffs are removed.

The trade route pioneered by Yichen and the Akatsuki Organization stretched from the coast on the other side of the Land of Earth all the way to the border between the Land of Rain and the Land of Sand.

Yichen estimated that there were about seventy or eighty caravans traveling along this trade route. Among them were caravans from countries other than the Land of Earth and the Land of Rain, as well as caravans from other small countries. For example, caravans from the Land of Bears, the Land of Demons, the Land of Birds, the Land of Grass, the Land of the Falls, Land of Iron, which are located near the Land of Earth, were among them.

Originally, their caravans were going to distant countries, and because they had to pass through many countries along the way, they would have to pay a lot of tariffs. However, by transiting through the Land of Earth, they would not need to pay tariffs. This was because, after seeing the booming trade between the Land of Rain and the Land of Earth, Ōnoki had persuaded the Tsuchikage to abolish all tariffs.

Nowadays, caravans from various countries travel through the Land of Earth. Firstly, because the Land of Earth is exempt from tariffs, and secondly, in order to protect the safety of trade routes, the Iwagakure has made great efforts to eliminate bandits within its territory in the past two years.

Currently, there aren't even a single missing-nin in the Land of Earth, and at least in most areas, caravans can travel safely without ninja escorts.

Therefore, it is a consensus among all merchant caravans in the entire Ninja World that as long as they travel through the Land of Earth, they can save a lot of costs.

For some caravans that are far from the Land of Earth, when they need escorts, they usually issue a mission like this: have ninjas escort the caravan to the Land of Earth border, and then after the transaction is completed, issue another mission in the Land of Earth, having ninjas escort them back to their original location from the border.

The flourishing commerce has brought great benefits to the economy of the Land of Earth. The tax revenue of the Tsuchikage has not decreased due to the reduction in tariffs, but has actually increased significantly. This development momentum is even catching up with that of the Land of Fire.

However, Iwagakure has not yet fully established a second trade route, since other countries do not have idealists like Akatsuki Organization.

However, Yichen heard that the Tsuchikage and Ōnoki were sending people to negotiate with the surrounding small countries, and he estimated that a second and third trade route would appear soon.

However, these things are no longer of much concern to Yichen. After two years of stationing himself at the Supply Station, Yichen is about to reap the rewards. In these two years, Yichen's Team 7 has only returned to Iwagakure three times.

Fu and the other two could take turns going out for a stroll from time to time. Yichen, however, could only leave once, after obtaining permission from the village and after the temporary commander arranged by the village arrived at the Supply Station.

It's fair to say that Yichen was practically suffocating.
