After a simple but hearty dinner, everyone was ready to rest early.

Dinner is simple because supplies are scarce here. Although it is a new supply, it is still a little simpler than the food in the mainland. It is said that it is rich because the company did its best to entertain them, so to speak, and served all the delicious food. So it can be said to be very rich, at least very rich for the warriors.

It may be because of the relatively high altitude, or it may be that the two days of travel are tiring, so everyone chose to rest early. Because it is a newly built barracks, the accommodation conditions here are better than the previous military station.

The two girls finally had their own rooms, and Han Li and the others didn't have to huddle together with the other warriors. So this night, everyone had a good rest.

Early the next morning, Zhao Xi and the male photographer will patrol along the border with the soldiers, which is also the daily task of the Shenxian Bay Border Defense Company.

In addition to stationary posts, they are also responsible for patrolling the border of several tens of kilometers. This patrol is a short-distance patrol mission.

On the one hand, it is a supplement to their periodic patrol tasks, and on the other hand, it is also to facilitate Zhao Xi's filming and interviews.

Because yesterday Zhao Xi proposed to Company Commander Liu that he wanted to follow them on patrol and film some of the patrol process. Although Company Commander Liu considered their physical fitness and persuaded them, at Zhao Xi's insistence, the company finally agreed, and arranged a short-distance patrol mission for them to follow.

And He Yuan and Zhang Chunli, two literary and artistic soldiers, got up early for morning classes, and then prepared for the condolence performance in the evening.

As for Han Li, he also has his mission. He was going to hold a reading party in the afternoon, to which the fighters were invited. The so-called reading club is to tell everyone about a book, or to tell a story, to tell everyone the content of a book.

In addition, it is some reading experience and experience, etc., anyway, it is such a symposium-style cultural activity, which is also an activity to send culture into the barracks.

Han Li's story is naturally his work, and the only one of his works suitable for telling soldiers on this occasion is his second "War Era".

The first book "Raiders of the Lost Ark", although it also tells about war, but most of them are some Raiders of the Lost Ark adventure stories, which are not suitable for this occasion. The third book, "War of Civilizations", is about a war between a scientific and technological civilization and a fantasy civilization, and there are ghosts and gods involved in it, which does not conform to materialist theory, so it is not very suitable.

So from this point of view, "Age of War", which has a strong science fiction color, is the best choice. And Han Li's theme today is not to communicate with the soldiers around the stories in the whole book, but around some of the future conceptual weapons and equipment mentioned in the book, which is also the content that the soldiers are most interested in.

If there is a breakthrough in directed energy weapons in the future, I think laser weapons will become the new favorite of warfare. Especially in space operations, the role of laser weapons will be brought into full play.

If the existing battery technology, as well as the power of the individual laser generators, are increased by breakthroughs. If the equipment itself can be well miniaturized, then the laser gun will replace the existing firearm as the main combat weapon of the future.

The principle of laser destruction of the target is actually to gather a large amount of energy on the target in a very short period of time, so that the target (surface) is subjected to strong thermal energy and the temperature increases sharply, so that the point quickly melts or vaporizes due to high temperature, so as to destroy the target.

The longer the exposure, the greater the damage to the target. Conversely, the shorter the exposure time, the less damage the target will suffer.

And this principle can also be applied to laser weapons, or laser guns. The longer the wavelength of the laser wave, the more powerful it is. During the irradiation period, the wavelength of the light wave is shorter and the power becomes smaller.

At the same time, this irradiation time is related to its rate of fire, to put it simply, if you want the laser weapon to be more powerful, you have to reduce the rate of fire and increase the wavelength of the light wave. In order to achieve a high rate of fire, it is necessary to shorten the wavelength of the light wave and reduce the irradiation time.

But even so, its long-wave rate of fire is several times higher than that of the machine gun currently with the highest rate of fire in the world, while the short-wave rate of fire will reach an astonishing height.

Of course, it's the power of the laser generator and the energy stored in the battery that underpins all of this.

……

The exoskeleton system, the exoskeleton full-body protective armor evolved from the exoskeleton system, referred to as Iron Man technology, and the robot technology evolved from Iron Man technology......

Han Li's narration seemed to open up the space for the imagination of the warriors, so it received an enthusiastic response. The warriors also let go of their previous restraints, joined in one by one, and began to have a heated discussion.

The so-called threesome must have my teacher, and Han Li also learned a lot from the discussion of the soldiers. A lot of things that the warriors say are from their shoes, such as the Gundam. Although there was a heated discussion about the Gundam, in the end, everyone unanimously rejected the Gundam's combat effectiveness, believing that it was useless.

I feel that although this thing is big, it is useless on the battlefield. In the words of the fighters, it is that the target is too big to hide, it is easy to be attacked, and so on.

On the contrary, everyone is very interested in the steel suit worn by Iron Man, that is, the exoskeleton full-body protective armor developed by Han Li with the exoskeleton system mentioned earlier, thinking that it is more in line with the future battlefield environment and more suitable for individual use.

In the end, because of the relationship of time, the reading club ended in everyone's reluctance. In the words of the warriors, it is not enough. Even after the evening condolence party, there were fighters arguing on this topic.

Early in the morning of the third day of coming to Sanctuary Bay, Han Li will say goodbye to this place and start their return journey.

Although both parties wanted to get together for a few more days, the limited conditions and the itinerary made them have to leave.

Facing the figures of the soldiers waving goodbye one by one, Han Li and several of them cried. The two girls were crying even more, reaching out the window and waving vigorously.

Although Han Li was not as exaggerated as the two girls, his eyes were red and he burst into tears. Especially when I hugged and said goodbye to the soldiers one by one, it felt as uncomfortable as cutting my heart with a knife.

In the following days, Han Li and the others were on their way back. This condolence activity is basically over, so they will drive from Yutian across the desert kilometers to Wushi to meet the condolence group there, and then end the nearly 20-day condolence trip.
