According to the direction of the passage, I finally found four exits. The passages were three or four meters wide and about three meters high, one of them had collapsed in the middle of the way, and the other three, all two kilometers away from the warehouse, had wide entrances, but they were all in extremely wooded places, obscured by plants, and difficult to be spotted.

The crowd carefully examined the vegetation and creatures near the entrance, sampled the environment, and finally confirmed that there were no mutated creatures running out of these entrances.

Considering that those beings do not have organs such as eyes, it is believed that they are a creature that is accustomed to living in a dark environment underground, and will not run to live in the sun.

The next day, with the arrival of a transport plane, 704 sent more advanced equipment.

After such a big incident, Lu Chen thought that 704 would send a commander who was more senior than Nangong Muxue, but he didn't expect that Nangong Muxue was still the supreme commander, and only some agents and experts were sent above, plus some equipment.

Lu Chen couldn't help but be secretly weird, they also trusted Nangong Muxue too much...... Belch...... No, Qin Lao knows that his brother is here, this is to believe in his brother's strength!

However, if you ask my brother to help, shouldn't you pay some price? My brother doesn't work for free!

Wait until you go back, let Qin Yushi and her father talk well.

Thinking of Qin Yushi, he couldn't help but think of yoga, and Lu Chen's heart couldn't help but move...... Do you want to teach Asuka Mochida Yoga......? It's a must!

……

Just thinking about what she didn't have, Nangong Muxue walked over and said, "Lu Chen, ...... next You command. ”

Lu Chen was stunned for a moment, "Just kidding, the commander here is you." ”

"I found that my abilities ......"

"Your ability needs to be ......improved," Lu Chen said, "But the improvement of your ability needs to be tempered on the front line, you continue to be your commander, and I will be your military advisor." ”

"That'...... Thank you!"

"Your own people, don't be so polite. Lu Chen smiled, "Take me to see the new guy sent this time." ”

"Okay......

Nangong Muxue immediately took Lu Chen to the temporary equipment warehouse.

In the equipment library, there are three humanoid equipment that look like robots.

Lu Chen couldn't help but smack his lips, "I'm obedient, humanoid mecha! This thing has been developed? Why hasn't it been made public? If this thing is equipped, the combat effectiveness is proper!"

Nangong Muxue shook her head, "After calculation, this complex humanoid mecha is not suitable for large-scale warfare, especially not for use in high-threat environments. ”

"Why?" Lu Chen said with a smile, "Mecha! It's a cow × in the cartoon." ”

"It can only exist in cartoons. Nangong Muxue said, "The current technology has not been able to make the mecha more flexible than humans, and the materials have not broken through, the protection is even inferior to the infantry fighting vehicle, and the large-caliber machine gun can be broken, only in small-scale special operations has some uses, but it is not irreplaceable, and the exoskeleton with a simple structure is better than this." ”

Lu Chenmo rubbed his chin, "You're right, this thing is just a look." Speaking of which, it seems that only now is the occasion that is more useful. ”

"Yes, so three were sent above, and by the way, you can assess its combat effectiveness in practical application. ”

Lu Chen nodded, "What is the weapon?"

"Chainsaws and machine guns. Nangong Muxue said.

"No flamethrowers or anything like that?"

"Yes, but not in an underground environment. Nangong Muxue said, "Underground fire will consume oxygen." ”

Lu Chen smiled, "Give me a feeling?"

Nangong Muxue nodded, "You can give it a try." ”

Lu Chen followed the technician's explanation and got into the mecha.

The height of this mecha is two meters five, and the height of the operator must not exceed one meter nine, and it can work for six hours when fully charged.

The armament is a three-barreled 23-mm cannon plus a sharp chainsaw, which can be used in both long-range and melee combat.

After manipulating the mecha and walking around and testing the strength, Lu Chen stopped the test, and after coming down, he said to Nangong Muxue: "Yes, with this thing taking the lead, the casualties will be much smaller, except for the mecha, what about other people's equipment?"

"According to the most powerful biochemical heavy infantry equipment. Nangong Muxue said.

"Hmm......" Lu Chen said, "I'll wear infantry equipment, this mecha is too clumsy for me, and I'm not used to it." ”

"You want to go down?" Nangong Muxue said, "I think you should command from above, didn't you say that I should be my military advisor?"

"As far as I know, the infantry system on the Huaxia side has completed decentralization, and each infantry can be used as a command node, you can just transmit the overall situation to me. Don't delay me from fighting. ”

"Okay. Nangong Muxue said, "I will open your infantry terminal authority, and all the information of the entire operation can be transmitted to you." ”

Lu Chen suddenly smiled and said, "Mu Xue, you have made progress, this time I know that you should be in command above!"

Nangong Muxue's face flushed, "Catch the ducks on the shelves." ”

Lu Chen laughed, "I'll help you this time, it's quite interesting to watch you slowly grow into a commander." ”

……

The plan of action was quickly formulated, first of all, it was necessary to destroy two of the three passages with deception medicine, and then send troops to attack the underground maze from the last passage, and arrive at the designated location to plant the deception bombs to destroy the entire maze.

In this operation, the three mechs were in the vanguard, followed by the heavy infantry, and the mecha opened the way when they encountered an attack, and the heavy infantry behind attacked the fish that slipped through the net.

Lu Chen thinks that this action is similar to playing StarCraft.

But there is no other better solution, so it can only be done for the time being.

……

Everything was ready, and I was about to act, when suddenly a lightning bolt pierced the sky, and it rained.

Lu Chen smacked his lips, feeling that this was not a good sign.

Boom! Boom! Boom!

……

A series of muffled explosions rang out, and it was the explosion of explosives that destroyed the other two passages, which meant the beginning of the operation.

Although Lu Chen was not the overall commander, Nangong Muxue handed over the command of the front line to him.

"Brothers, let's act!" Lu Chen's orders were nondescript, but the people of Seventy-Four were also familiar with him, knew his ability, and did not be verbose, and began to move forward silently.

Three mechs were in front, and thirty heavy infantry were divided into ten three-person battle teams, slowly following behind.

According to the width and height of the underground labyrinth road, the number of thirty people is just right, and if there are more people, it will be too crowded, which will affect the combat effectiveness.

Knock! Knock!

With the heavy footsteps of the mecha, Lu Chen led a team of heavy infantry into the deep underground world......
