A huge transport plane slowly landed on the cleared temporary runway.

Because the snow in Lucia is thicker than that in Yanguo, the runway is actually just the compacted snow and the marked navigation lights.

However, the huge transport plane is still very stable at the end of the runway, there is no accident.

"What are the goods and materials delivered this time?" Standing next to the plane, looking at the cargo unloaded from the cabin, Chen Xin inquired to the staff.

This is a small upgrade on the performance of the core sent by China. Chen Xin further optimized it to improve the heating efficiency and coverage area. In this way, it can affect more people and provide more survival points for Chen Xin.

Although the number of survival points that Chen Xin can gain from a refuge is online, no one has said that this energy tower is only for one refuge.

The situation in the capital of Lucia is different from that in the Republic of Yan. Most of the underground refuge facilities here come from the suvian era. Some of them are dug very deep, even more than a meter underground. For example, the capital subway station is such a deep existence.

But in addition, the capital of Lucia has many shelters similar to private basements, most of which are products of that era.

At the beginning, Lucia government did not have as strong executive power and infrastructure capacity as Yanguo, so it only connected a small part of the basement together and built a refuge similar to the community, so it put its main strength on the large refuge established by the government.

In this case, the scope that can be covered by the establishment of the energy tower should be the scope that the pipeline can be laid, not just the scope that can be affected by the heating place of the energy tower.

Moreover, the lucians didn't plan to build this energy tower on the ground, but on the ground. So what the lucians adopted was Chen Xin's original design of the second energy tower, which closed the heat dissipation of the whole tower body and relied entirely on pipes to transport heat.

This happens to be in Chen Xin's favor, because in this way, the pipeline can connect more refuges to avoid the upper limit of the number of survival points that can be obtained by opening a refuge.

As for Chen Xin, he can upgrade the heating pipeline and energy tower to influence more shelters and survivors, so as to gain more survival.
