Seeing Lu Jun say this, the girl in red also touched the round mines on the ground and said, "But the people buried around us don't know, what if they are blown up when they come back?" ”

After the girl in red asked this question, Ruan Bing and Ruan Xue also set their eyes on Lu Jun, waiting for Lu Jun's answer.

"Don't worry, this is a G20 intelligent induction mine, it will distinguish between enemies and friends, as long as the enemy steps into the area they sense, it will explode, and our people will be fine when they step into it, as for the principle, I don't understand, anyway, that's what the introduction says." Lu Jun spread his hands and explained to the women.

Hearing Lu Jun say this, all the women showed expressions of sudden realization, and they touched these round induction mines again.

"Okay, let's bury it separately, just dig a small pit and throw it in, pay attention to concealment, if you find it out in advance, it will be troublesome." Lu Jun picked up a sapper shovel and picked up an induction mine and said to the women.

Although it's far from the research institute, they're safe, but the Silent Crusaders have searchlights and patrols, so they have to be cautious.

When the women heard the order of the road army, they all nodded, picked up the sapper shovel and the induction mine and scattered to get busy......

In this way, in the following time, Lu Jun, Ruan Bing and others spent time in laying mines, and soon their place was full of mines.

But in addition to this location, there are also main roads and other locations waiting for the road army to bury them, but the road army found that the efficiency of the four of them was too low, and it was dangerous to rush over to the side of the main road.

So for the sake of efficiency and insurance, Lu Jun spent 5,000 dragon coins to buy three small robots that specialize in laying mines from the trading module.

These robots are activated by A-tier hedron and have a one-cube hidden space in their body, similar to the space of the Road Army's armed mods, which can place a large number of mines in them.

With a high-speed rotating drill bit under his feet, he can instantly dig up the ground and put mines in, and it takes less than a second to bury a mine, which is much more efficient than Lu Jun and others.

On top of that, these robots have a bionic coating that blends into their surroundings during the day and at night, greatly increasing their concealment.

Looking at the small robots that had already begun to work, Lu Jun silently prayed in his heart that these robots and sensor mines that cost him nearly 10,000 dragon coins must work, otherwise he would lose a lot......

As time passed, more than an hour passed quickly, during which the robots worked smoothly, silently planting nearly 3,000 induction mines around the research institute, and they have not yet been discovered.

Looking at the robots who returned to the same place after completing the task, Lu Jun was very satisfied, and took back all three robots and kept them for next time.

But Lu Jun was a little irritable in his heart, because after so much time, they had no news from Mu, could it be that something happened?

Just as Lu Jun was thinking wildly, a deafening sound suddenly sounded from an unknown location in the distance, and a mushroom cloud rose up, and you didn't have to guess to know that there was a huge explosion.

However, all this did not end with the explosion, because Lu Jun found that the lights on the entertainment area had all dimmed three seconds later, and the brightly lit scientific research institute was also plunged into darkness.

"It's them! And they succeeded! Ruan Xue shook her fist heavily, with a bright smile on her face.

When Lu Jun heard Ruan Xue's words, he also grinned and nodded, indeed, all this means that Mu and the others have destroyed the power system in the inner city, and judging from the sound of this explosion, it is absolutely impossible for the power to be restored in a short time.

But before the army could say anything, there were also bursts of explosions from the entertainment and residential areas of the inner city, and these explosions were very inked, most likely grenades or rockets exploding.

After the explosion ended, it was clear that the originally dark entertainment and residential areas were lit up by fire, and they spread rapidly, illuminating the dark night sky red.

Seeing this, Lu Jun and the others knew that Anan and the Northern Lion had also started to act, and they came completely according to Lu Jun's plan, and everything went very smoothly.

Just after these events, a large number of figures with flashlights or gunlights suddenly ran out of the quiet research institute, their voices were confused, as if they were anxious to know what was going on outside.

However, in the absence of communication and electricity, it is impossible for them to contact the outside of the research institute, and they can only look at the entertainment and residential areas where the fire is getting bigger and bigger.

In the end, it may be that the commander of the scientific research institute couldn't stand it anymore, and couldn't help but send several teams of people to drive in the direction of the entertainment area in off-road vehicles, wanting to find out about the situation.

But the road army planted a large number of mines around the scientific research institute, and when these off-road vehicles reached a certain position, the mines were triggered.

Only a "boom boom ......" was heard, and all the off-road vehicles rolled over and exploded, and none of the people inside survived.

And a large amount of smoke and fire rose from the site of the mine's explosion, which may be a collateral effect of the mine.

Seeing this, Lu Jun also danced his fist, expressing his inner excitement, he was too satisfied with the effect of these mines, originally he was worried about whether these mines could block the off-road vehicle, but he didn't expect to directly blow up the off-road vehicle to the slag, which greatly surprised him......

And the defenders of the scientific research institute who also watched all this had a headache, because of the smoke blocking, they didn't know why the off-road vehicle exploded, so they could only sound the alarm of the scientific research institute in confusion.

But seeing that after the explosion fell into silence again, the commander of the scientific research institute was a little annoyed, and once again sent a team of people out without giving up.

It's just that instead of riding in a vehicle, the group chose to hike, and they had to see what was going on outside.

But this team had just walked to the area where the off-road vehicle exploded, and there was a sudden loud noise, coupled with smoke and fire, which directly "dissolved" the team into the night, and none of them survived......

Seeing this scene, the people of the scientific research institute also knew that they had been attacked, so they stood around the scientific research institute with weapons in their hands, and did not go out again, thinking in their hearts who had the audacity to attack the scientific research institute in the inner city......
