The officials on both sides came to each other's cities for a meeting, and of course they visited and inspected each other, and when the officials held a meeting on each side and made sure that there was no malicious intent on both sides, a large-scale public visit began, and for the citizens who could only live in their own cities, such a visit was already equivalent to tourism.

The meeting went very smoothly, and many cooperation projects were passed, such as the research on magic science conducted by the two sides after the fall of the Langton Empire, although the conditions were limited, and everyone's research results were not much, but after the researchers of both sides got together, different ideas would definitely bring new developments, and for example, the troops of both sides carried out exercises, which could only be carried out with troops in the same city before, everyone was an acquaintance, and the combat effectiveness was already quite clear, and the exercises with unfamiliar troops could also improve their combat skills.

And the largest cooperation, is the exchange of population, as a former fourth-level civilization, although the magic science of this world and the development direction of science and technology in the main world are completely different, but the harm of marriage between close relatives, the people of this world also know, but everyone lives in the same city, so long time has passed, there is not much communication with the outside world, which leads to the blood relationship of all people getting closer and closer.

Although the population is large, even if there is a kinship, it is three generations away, but the trend of blood degradation is in the eyes of everyone, although three years ago I also met another city, but at that time the other party did not have a Natalia-like character, and He Ping had not yet appeared, so they did not trust each other, and in the end, although there was a certain exchange, it was very shallow, and no one proposed to exchange population.

This time, the city of Garth and the city of Garland are close to each other, which can be said to be a godsend, for many people on both sides, especially young and middle-aged people, have long been tired of living in the city and unable to go out. The love has not yet receded, unlike many old people who are reluctant to leave their hometowns, therefore, after hearing the news, many people on both sides responded positively, and even some people who have already started a family are willing to take their families to live in another city.

The final result, the two cities are willing to respond to the call of the exchange population of more than 50,000, in line with the principle of one person into one person, the two sides finally set the number of people to exchange at 50,000, each side sent 50,000 people to each other's city, and need to be responsible for the residence and work and study of these people, this is not a small project, the people who participate in the exchange need to immediately start preparing to move, but also to hand over their work to other colleagues, job vacancies, I can only wait for the people who have moved over from the other side to settle down before recruiting.

All the people in the Senate (Temple), the town hall and the council began to work overtime, so it was important to make this exchange a complete success, without any flaws, not only to ensure that the people who went out had a comfortable new life, but also to ensure that the people who came from the opposite side could adapt as soon as possible.

And He Ping was not idle at this time, he and Natalia, and more than a dozen young men and women were concentrated in the temple of Garland City, Hans, James, Victoria and Noelle and other squadron leaders of Garth City were impressively listed, and the remaining few young men and women were young officers of various units in Garland City, and the reason for gathering here was very simple, except for Natalia who could not leave Garland City, the rest of the people were the main force of the ruins exploration plan they had discussed before.

The two biggest problems in ruin exploration, one is to find the location of the ruins, and the second is how to reach and enter the ruins, the first problem is not difficult, with Natalia's prophetic ability, plus some maps left behind, determine your current location on the map, and find the nearby ruins is not a difficult task, the key is that the second problem has almost no way to solve, the ruins have been entrenched by the demon worm for a long time, once the demon worm is alarmed, let alone the exploration team, even the city is in danger of extinction.

"The number of people can't be small, but it can't be too much, especially when you enter for the first time, only a few masters can go in to find out, and then you can adjust the personnel structure according to the actual situation." He Ping said his opinion, no one knows what the situation is in the ruins, but it will definitely not be safe, if the strength is not good, it can only cause trouble if you go in, and you also need other people to protect it, if there are too many people, it is easy to expose your whereabouts and attract demon insects.

"And how do you get to the ruins?" Natalia raised her own question: "You must not let the city beast move to the vicinity of the ruins, such a large target will definitely cause a large-scale swarm attack, it is too dangerous for the city, but it is too slow on foot, the magic guide car is a good choice, but there are also many restrictions." ”

He Ping nodded, this is not a small problem, although the magic guide car is fast enough, but it is more picky about the road conditions, and it cannot act on some special and complex ground, and at the same time, the space of the magic guide car is also limited, and it can't contain many personnel and materials, considering that it may be attacked by the magic worm, it may pass through the area where the demon worm is located, etc., the magic guide car can only be used as a backup option, which is not a solution.

"That's right!" He Ping had an idea: "Can we redevelop a new means of transportation?" In the past, because it was limited to the scope of a city, it did not put much effort into the development of transportation, but now with researchers from both sides, if we can provide a general idea according to the actual requirements of this exploration, how likely is it that researchers will develop new means of transportation? How much time does it take? ”

New Vehicles! He Ping's proposal immediately aroused everyone's interest, indeed, there was not much research on transportation before, because the scope of activity was only within the city, and the highest-end ones were only magic buses and trucks, and the flying machine had no meaning, losing the city as a support, and always facing the threat of magic insects, no one wanted to use the aircraft in such an environment.

But now, they have a reason to go out, and the existing means of transportation cannot meet their needs, and the development of new means of transportation is urgent.

"Great idea! If there is a vehicle that can carry dozens of people and can carry a certain amount of supplies, it will be a good way to go out in the future! ”

"It's best to add the function of flying, land and air, walk on the ground if the road condition is good, easy to hide yourself, and fly over when you encounter special terrain!"

"If there are some achievements in the research and development of weapons, can some heavy weapons be loaded on them and obtain a certain combat effectiveness?"

"And the shield! Don't forget the defense! ”

Hearing this, He Ping thought of some ideas again: "With my attribute-free adaptability, plus the silver obsidian circuit, I can have an invisible function!" ”

ps:There will still be two more tomorrow.,There will be no notice for the next two changes.,The status is not good to update the abnormal.,Or when you want to add a change.,I'll notify you in advance.。
