When the sun once again shone across the narrow river valley, a secret excavation mission commanded by Hao Yi himself began.

The logistics unit of the reinforced mixed corps was ordered to urgently bring in all the construction machinery that could participate in the excavation operation, including small SVC engineering machines and large nuclear-powered deep well excavators. In addition to this, the commander of the logistics troops was authorized to call on the power of any engineering machinery at any time to the large rear. This made the colonel, who was over half a hundred years old, feel flattered.

"From this area all the way to here, vertically, the excavation depth is at least 100 meters, and the excavation work must not be stopped until a huge hole is dug into the ground! Do you understand? Standing on the towering cliff on the side of the river valley, Hao Yi drew a circle with a radius of more than 100 meters on a holographic electronic map at hand, and commanded the logistics commander beside him in a deep voice.

"Such a large area? Uh, uncle, can you ask your subordinates what we are going to dig up this time? The bearded colonel was slightly stunned when he heard this, and asked in a low voice in surprise.

"Colonel, don't ask what you shouldn't ask, anyway, you just need to know that your task is to dig up a living treasure for me from the ground! As for what this living treasure is used for, as a high-ranking military officer, you should also know what is called a military secret, right? Hao Yi coldly reprimanded the old colonel, then turned around and left in a hurry with a group of staff officers.

"Why are you still stunned? Didn't you hear what my uncle said? Don't ask what you shouldn't ask, shut up Lao Tzu if you shouldn't be verbose! Hurry up and work for Lao Tzu, before dark, if you can't dig the depth specified by your uncle, you will all fucking jump in for Lao Tzu and gouge them one by one! ”

Watching Hao Yi's thin back gradually fade away, the old colonel, who was irritable for no reason, turned around and scolded his subordinates who were standing tall and upright.

After scolding, the old colonel still held back the curiosity in his heart and commanded the logistics troops to quickly launch the excavation operation.

First of all, the Fifth Mixed Division sent a large number of marines to assist the logistics engineers in cleaning up all the insect corpses and those broken and charred insect buildings in the designated area. Then, various types of excavation construction machinery began to wield all kinds of tools, digging through the already blackened soil layer, with bursts of thunderous engine roar, little by little disappeared from the ground.

Originally, according to the estimation of the experienced old colonel, with the working efficiency of the existing excavation construction machinery, it was completely possible to dig the soil layer specified by his uncle Haoyi before dark. However, what the old colonel didn't expect was that after the excavation work began, all kinds of unexpected situations appeared repeatedly.

After Xiangxia dug less than ten meters of soil, a fishy and sticky white mucus inexplicably oozes from the originally black and red soil. Not only does this slime make the soil more complex and much more difficult to excavate, but it also appears to be highly corrosive. Small construction machines, such as SVCs, simply cannot carry out excavation work in such an environment. Their armor, as well as the clear glass shield in the cockpit position, are not effective in stopping the erosion of this slime.

As a last resort, the Colonel had no choice but to order these small construction machines with weak armor to withdraw from the excavation work. However, it didn't end there. In the extremely complex soil layer under the base of the insect nest, a variety of stones with considerable hardness appeared, which actually caused various failures in the excavation equipment of those large construction machinery.

In less than half a day's effort, as much as half of the large construction machinery of the logistics unit was damaged. This made the old colonel very angry, but he was helpless.

"Holy shit, this soil is so complicated, how did those beasts get out of the ground? Could it be that they are all copper skin and iron bones? Looking at the piles of damaged construction machinery with black lines, the old colonel's depression naturally went without saying.

After dark, when helium lamps lit up in the ruined hive base, the logistics force dug less than a third of the depth.

"Immediately request the headquarters to dispatch more construction machinery support, and be sure to dig to the specified depth within three days!" Standing on the top of the hill and glancing at the depth of the big hole at the bottom of the valley, Haoyi frowned slightly, and gave a loud order to the staff officers behind him.

Half an hour ago, Hao Yi used the heart of the swarm to communicate with Lei, and learned that this goblin bug had become extremely weak, and if it was not dug out of the depths of the earth as soon as possible, it might suffocate to death in the depths of the earth. After all, the heart of the insect swarm almost concentrates eighty or ninety percent of the essence in the brain worm's body, and the rest can only barely maintain its minimum survival needs. Moreover, before leaving, Haoyi also solemnly warned Lei not to devour the heads of those humans again in order to absorb spiritual energy. Therefore, Ray is almost trapped deep underground without eating or drinking, and its miserable situation is self-evident.

The next day, the reinforcements who were urgently dispatched brought a large number of more advanced construction machinery, and the excavation progress finally made substantial progress.

At noon on the third day, the engineers finally dug the hole where the mine was. When the meat caterpillar-like thunder appeared in broad daylight, all the officers and soldiers involved in the excavation operation were stunned. Of course, the two piles of human heads in the cave and the feces of the mountain-like thunder also made many soldiers vomit again and again.

"Uncle, are you going to get that thing out of the ground?" The commander of the logistics unit, the colonel, looked at the mountain of thunder, stammered and turned back to ask Haoyi.

"That's right! This guy is an important magic weapon for us to deal with the insects, we must find a way to get this guy up as soon as possible and transport it back to the base! Haoyi nodded, and explained vaguely to the size.

"But uncle, I estimate that with the weight of this guy, the existing construction machinery in our hands, I'm afraid there is no way to get it directly from the depths of the ground!" The colonel's old face couldn't help but worry for a while.

"Let the aviation help!" As the two spoke, a low roar was heard in the distance. Hao Yi looked up and followed the sound, and saw that there were five or six large transport planes arranged in a huge polygon, slowly flying towards this side, and below them, there seemed to be a huge square iron cabinet hanging with a thick wire rope. Haoyi knew that it must be a temporary cage tailored by Guo Ling for Lei. And it was the transport planes hanging from the cage that made Haoyi's eyes light up, and he raised his hand and pointed to the fighters hovering in the air, briefly reminding the old colonel.

"yes, I didn't think of those flying iron birds!" The old colonel suddenly slapped his head in realization, and hurriedly went to find the commander of the aviation force.

When the sky was dark, the gray-headed and dying Lei was finally hoisted up from the depths of the ground by five medical transport planes with steel cables.

"Master, if you dig me out of the hole in the ground half a day later, I'm afraid I'll suffocate to death!" When Hao Yi saw Lei who was carefully put into a special cage, Lei's slightly childish voice complained weakly in Hao Yi's mind.

"Okay, when I get back to the base, I'm treating you well, master!" Looking at Lei's pair of huge teary eyes, Haoyi was suddenly happy, reached out and patted Lei's fat and soft body, and smiled and comforted.

After successfully "rescued" the mine from the depths of the ground, Haoyi immediately ordered the withdrawal of the troops overnight, and asked the mixed fifth division to use high-yield high-energy explosives to re-blow up the entire insect hive base and this river valley solidly.

When a transport plane of the mixed legion Zuihou flew away, huge fireballs rose one after another, billowing black smoke soared into the sky again, and this so-called strategic counterattack against the alien insects came to an end.

"Uncle, how about this special cell? Can you still get into your eyes? ”

When the Marines tried their best to stuff the Roshan-like Lei into a prison cell in the Longtan base that was temporarily converted from the training hall of the Black Eagle Special Operations Force, Guo Ling proudly flicked the transparent holographic force field wall in front of him, and asked Hao Yi with a smile.

"Hehe, that's good, Lao Guo, I can't see it, you still have a talent for civil design!" Haoyi smiled and patted Guo Ling on the shoulder, looked at the specially made prison cell in front of him with great interest, and praised it sincerely.

The cell is located in a corner of the training hall. The two stainless steel back walls of the hall, which were large enough to withstand direct fire from large-caliber artillery, and three pillars of energy that could create powerful holographic force field walls, formed a solid cell with two sides transparent and closed on top. Two of the three pillars of energy were firmly embedded in the steel back wall, while the other was buried deep beneath the steel floor of the hall. Even the removable ceiling on the roof of the cell was welded from the thick steel armor used by the three layers of ships.

From the eyes of ordinary people, this is almost a solid cell that cannot be shaken at all. However, Rao is like this, Haoyi, who praised Guo Ling in his mouth, is still faintly worried in his heart.

Haoyi knew that if Ray hadn't been hit hard by himself and had given the Heart of the Swarm to himself, this so-called cell would not have been able to trap it at all.

"Well, in fact, this is all the method that those rabbit cubs under my hand came up with, because the time is too tight, and I can only make do with it first!" Guo Ling obviously also knew that this seemingly unusually strong cell was not worth mentioning at all for a brain worm that was once the supreme commander of the entire star region insect swarm. Therefore, although he heard Hao Yi praise himself, Guo Ling's heart was not easy, and he frowned slightly and asked in a deep voice: "Uncle, do you think that guy inside will be angry and tear down all this place?" ”

"It dare!" Haoyi glared at Guo Ling, and shouted loudly: "Then Lao Tzu has to pick its skin and pump its tendons first!" ”

"Then master, don't be busy trying to figure out how to peel my skin, I'm dying of hunger now! For the sake of the life of the most powerful and invincible pet bug in your universe, master, let's get some food first, right? At this time, Lei's childish voice echoed in Haoyi's mind again.

"Yo hey, you're really fucking shameless, and you're the most powerful and invincible? Who did you learn this from? Hao Yi was immediately happy when he heard this, and suddenly shouted at Lei, who was hiding in the prison cell, looking around curiously, which frightened Guo Ling beside him, and thought that Hao Yi was talking to him.

"Hehe, didn't you learn this from the most handsome, dashing, and powerful master in the universe?" The next moment, Lei's sycophant almost didn't make Haoyi directly scorched on the outside and yellow on the inside......
