The wheels of time slowly and continuously ran over the past, and the Soviets seemed to have acquiesced to the fact of defeat, and when they were ambushed by Liszt on the eve of the blizzard, almost all the helicopters were annihilated, and their land aviation regiment could almost be said to have been lost. They have lost the ability to deploy troops, and in the face of the complex mountainous area covered with heavy snow, they have also chosen to accumulate strength and wait for the spring of the next year, as well as the build-up of even larger troops.

In just one week's time, the air force from the Siberian Military District and the Bering Strait Military District has used Il-76 military transport planes to transport a large number of elite Soviet troops from various units on the mainland, and Soviet troops with battalions as the basic unit have also assembled on the Queen Charlotte Islands. Moreover, most of them are light infantry and light armored units suitable for mountain warfare, as well as a small number of armed helicopter gunships, which are completely positioned according to mountain warfare.

But all this is also unpredictable for Liszt, who is deep inside the cave base, because he has no access to the outside world, and he has no idea about the assembled troops on the Queen Charlotte Islands. Of course, this is also the opposite, even the size of Liszt's own troops is a mystery to those Soviets and Canadians.

In the current cave base, a week's time is enough for this group of idle and energetic marines to basically improve the facilities they need. As the engineering task was arranged, the small-scale blasting in full swing appeared deep in the huge Rocky Mountains.

However, their task is not complicated, after all, the various caves and tunnels have been excavated by them as early as two months ago. And now the task is only to make the rough areas as smooth as possible. At the same time, the grooves of the lines are dug out in the tunnels and karst caves. to connect the thick wires to the storage boxes in each cave.

Gentle lights have also appeared in all corners of the cave. The thick industrial lines have been built in the grooves, and the voltage regulators and sockets that have been shunted have also connected the large and small lamps. The lights in the tunnel, the chandelier in the cave, have also been installed by the group of young men, and after the current is turned on, it releases a bright light, which will be in the originally dim space. The light is basically clear.

However, a Marine Corps soldier is still wielding a pickaxe, digging out the rock wall that was blown by a detonator, and digging and expanding the surrounding karst caves to make the space larger. The No. 2 karst cave, which originally covers an area of more than 2,000 square meters, has been listed as the main task goal of the expansion.

More than a dozen soldiers of the Marine Corps were standing behind Liszt, and on the top of the rock wall four or five meters above his head, six evenly distributed chandeliers, had also been placed in the cave space of more than 2,000 square meters. The photo is quite clear. And Liszt frowned and looked at the underground dark river that originally existed in front of him, and couldn't help but ask in a deep voice: "Old man." Can you really be sure that this underground river is enough to support the operation of the generator set? ”

This underground river, which is more than half a meter deep, used to be only a place to draw water from the base of the cave, and it has little other use except for the necessary water for daily use and the occasional open bath water. But a relatively young-looking Soviet expert followed behind Liszt and nodded in his non-fluent English: "Yes, although I am not a geologist, according to the trend of the Rocky Mountains and the distribution of underground rivers, I am sure that there is an even larger underground river under the underground river in this cave!" ”

The young Soviet expert also had affirmation in his tone, and when he looked at Liszt, there was a slight fear in his eyes. Liszt's grim appearance, which did not care about anything at all, directly shocked all the Soviet experts, especially the colleagues who were still lying on their sleeping bags and trembling and moaning in pain, and made them feel terrified.

And he swallowed slowly, still looked at Liszt and nodded lightly: "Generally speaking, the more than 100-meter-long dark river in the upper karst cave should belong to the result of the water level rising and overflowing in the dark river of the lower karst cave. He slowly walked a few steps forward, bent down and touched the rock formation at the edge of the dark river with his hand, felt the wetness on his hand, and nodded: "That's right, the rock wall under this depression is not smooth, it is completely caused by the different water levels in each season. ”

"If that's the case, after opening up the upper and lower layers of the dark river, you can place hydroelectric generating units?"

Liszt nodded slowly, although he didn't know much about geology and didn't know much about hydroelectric power, but the Soviet heavy weapons research expert in front of him obviously had studied these. In the past, he had also considered using the underground river with strong water to generate hydroelectric power, but now that the Soviet expert was the first to mention it, it was more secure from a professional point of view than he had imagined it alone.

"Yes, we have to dig the rock walls on both sides to make the area of this dark river larger, and at the same time use lifting tools to destroy the intervals under the dark river, and at the same time let the water of the lower river pour up."

With a stiff smile on his face, the relatively young Soviet expert nodded hurriedly, and at the same time stretched out his hand in front of him, pointed to the underground river that was still flowing very fast, and said to Liszt in stiff English: "We can choose a smaller hydroelectric generator set, which can not only protect the rock formation of the cave itself, but also facilitate installation." After a slight pause, he also nodded softly: "And small hydroelectric generators can also be safer for logistics transportation."

The suggestion of this Soviet expert is quite scientific and reasonable, and Liszt also nodded slowly, his eyes swept over the dark river in front of him, which almost spanned the entire karst cave, and was quite turbulent about half a meter, and he also subconsciously glanced at several rectangular objects more than one person high in the corner of the wall. With the completion of ventilation, lighting, and communication systems, this expensive exchange item has almost become a consumable.

Squinting slightly, Liszt's retina also appeared in the retina of various generators in daily necessities, whether it was diesel or solar energy, all of which were listed on it. But he still looked at the hydroelectric generator, especially the small household hydroelectric generator set, but the price of 500 points for one unit has already made him quite excited.
