Destroying the Outer Bone Base is not Ye Fei's main purpose, the more important goal is to encircle the point and draw out other enemies that may be hiding somewhere in this galaxy.

"Report, I didn't find it, but ......" Ruan Peng said halfway through, and suddenly hesitated.

"But what, big man, don't spit it out." Ye Fei glared at Ruan Peng impatiently.

Ruan Peng is thin, no matter how he looks at it, he doesn't look like a soldier, if he takes off his military uniform, he will be much different from the little white-faced nerd in school, so Ye Fei deliberately said this to make Ruan Peng's words and deeds more masculine.

"Yes, an anomalous magnetic reaction has been found underground, possibly a residual biospaceship." After speaking, Ruan Peng hurriedly added, "The location where the abnormal reaction occurred is very deep. ”

Neutron bombs mainly kill living targets through the strong neutron flow generated by nuclear explosions, but the penetration of neutron streams also has a limit, and the thick rock formations are fully capable of blocking the neutron flow.

"What is the vertical depth?"

"About four kilometers, based on previous scan data, it should be a huge naturally formed cavity beneath the island, and the explosion only damaged the outer layer of the cavity." Ruan Peng put forward his own judgment for Ye Fei's reference.

Ye Fei frowned, and thought silently for two minutes: "How much of the destroyed space occupies the total volume of the void?" ”

"About two-thirds of them."

"Where is the remaining space that can escape the power of the neutron bomb?" Ye Fei asked again.

Ruan Peng was stunned for a moment, he had never thought about this problem, and hurriedly began to calculate, fortunately, with the assistance of the ship's computer, he quickly came up with the answer: "There are two locations in the space that has been scanned, and there is also a possible place, but there is a hole leading to the deeper underground, and the scanning system cannot penetrate the formation, so I don't know what is going on under the tunnel." ”

"Damn, Lao Tzu has been fighting for so many years, and the spaceship hasn't sat for a while, but the hole has not been drilled." Ye Fei grinned and scolded, "I think the Command Academy should open another course, and it's called Cosmic Earth Cave Studies." ”

There was a burst of laughter in the bridge, and the solemn atmosphere was washed away by Ye Fei's humor.

"Why, you think I'm joking, don't you?" Ye Fei looked like he believed it or not, "The first time I met the Outer Bone Figures, it was in the hole they drilled out, and every time I ran into them after that, I inevitably dealt with the hole in the ground. I don't understand, it's an interstellar race, so I have to burrow into the ground like a mouse. Don't think that with a battleship, you can do anything to the outer skeletons, they drill into the hole like this, and they can't even get a neutron bullet. You say, no matter how strong a battleship is, can it go underground? ”

Everyone looked at each other as if they were ...... The captain wasn't joking!

Cosmic geo-insight? It's awkward just to hear the name, how can the Command Academy agree? Even if this course is opened, it should be opened to the University of Geosciences, right?

But think about it on the other hand, even if the University of Geosciences offers this course, where will those who study this find a job after graduation? That is, the commandos cleared the outer bone people in the crypt, so that they could use this kind of off-the-beaten-path knowledge.

"Okay, I'm not going to talk to you about it, Ruan Peng, has the temperature of the explosion cooled down?" Ye Fei asked suddenly.

"Huh? It's already dropped, and the current temperature of the blast is minus 42 degrees Celsius...... The internal temperature is minus 70 degrees. Ruan Peng suddenly felt that he was responsible for more projects, and involuntarily began to think about how to share some "business" with others.

"Good." The satisfactory answer made Ye Fei make up his mind, "Black Bear, Wu Fei, you two take your brothers down, don't give me face, don't leave me a single bone person." ”

"Hey, hey, look at it, boss." The black bear's eyes lit up, and he waved his fist at his brothers, and more than sixty commandos picked up the rifles in their hands and stood up in unison.

"Understood." Wu Fei, the other captain, gave an unusually concise answer.

Don't look at the huge size of the Yangtze River, but there is only one regiment of commandos on board the battleship, and Ye Fei is also the commander.

Such a large battleship carrying more than 100 commandos is simply a cannon to fight mosquitoes, but the Yangtze River is nominally an assault ship, but in essence it is a multi-purpose warship that emphasizes the ability to attack on the ground, and carrying commandos is only one aspect of the many functions of the warship.

On the other hand, after the large-scale expansion of the Chinese Celestial Army, the commando was reduced to three divisions, all of which were veterans who had participated in at least one foreign campaign, and only nine regiments were at full strength.

Just one battleship on the Yangtze River can take all three divisions away, but the Celestial Army can't hand over all the commandos to the expeditionary force, right? Moreover, the commandos who are willing to join the expeditionary force can't even get together a division. If it weren't for the special circumstances of the First Fleet of the Expeditionary Force, an assault ship would not even be worthy of a regiment!

Half a year ago, the head of the Heavenly Army began to have a headache, just the Yangtze River and the Yellow River transferred two regiments of troops, and the commandos who volunteered to join the expedition were less than one regiment at full, and if the 14 warships of the Second Fleet were delivered, they did not know where to draw people to gather the two regiments...... It was simply too late to retrain, and the remaining commandos could only continue to be mobilized.

Black Bear and Wu Fei took their respective team members and took six landing craft to break away from the mothership and quickly dive to the ground.

The monkeys left behind were so anxious that they turned around: "Boss, let me go down too!" ”

In addition to Black Bear and Wu Fei, the last captain was Ye Fei's old brother Monkey, and the only captain and captain.

Back then, Monkey and Scissors were transferred to the fleet and became battleship officers, and later Monkey also signed up for the expeditionary force. After Ye Fei learned that the elder brother had joined the expeditionary force, he immediately used his authority to find all the elder brothers from the list and transferred them all to his subordinates.

When the commando team was downsized, because of the lack of personnel, most of the officers in the positions were high-ranking and low-level. Those who are familiar with the army know that no matter how high the rank is, it is only superficially good-looking, with a penny on his shoulder, but in fact he is a second lieutenant and a staff officer. And the high position and low military rank, the rank will soon be promoted because of the relationship between the position.

The black bear and the jar caught up with the good times, and the ranks rose like rockets.

Scissors and Monkeys, who were transferred to the fleet, missed the good time, and although the ranks were promoted when the fleet was expanded, the speed was far from comparable to that of the brothers who remained in the commando.

The rank of captain of the monkey is only equivalent to the squadron leader, and Ye Fei arranged him in the position of the captain, which also has the meaning of promoting old comrades.

"No, I can't leave any mobile forces behind, can I? Don't worry, there is no chance this time and there will be a next time, if you enter the expeditionary force, can you still have less fighting? Ye Fei patiently comforted.

Having said that, the monkey can only accept the reality with a loss of heart.
