Hundreds of various bionic insects flew to all parts of the base and landed on radar and monitoring equipment, and the small atomic jamming systems they carried shielded all the monitoring systems of the base, making the enemy's monitoring system blind, and the reconnaissance birds constantly transmitted back to the layout of the base.

The staff officers who accompanied him first determined the location of the smelter, and the area near the smelter was the dormitory of the technicians. At this time, the smelter was still producing with the roar of machines, and the dormitory was already pitch black, and the people there should have fallen asleep.

About five kilometers to the east of the smelter, there was a brightly lit and heavily guarded area, a large area of bungalows, where patrolling groups of Marine mechs were constantly coming in and out, and finally it was determined that this was where the barracks of the enemy base were located.

On a large mountain in the distance, the naked eye can see some bright caves, and there is a sound in those hole-ridden caves, which are supposed to be mines that produce rare earths.

To the south near the barracks, there was a wide apron, where two frigates and more than a dozen large transport ships for transporting minerals were parked.

There is a large mecha fortress in each of the four corners of the smelter, and these four fortresses are very troublesome, and they cannot be attacked but can only be outwitted.

After determining the general distribution of the enemy's base, Jack gave the battle order, and immediately dozens of rats with miniature high-explosive nuclear bombs in their bodies were released, and they ran quickly in the dark, lurking around the enemy barracks unconsciously, quietly waiting for the moment of detonation.

Jack divided the 200 mecha fighters into five groups, the first group led 30 people to solve the smelter, the second group of 30 people to solve the smelter dormitory, the third group of 30 people to solve the tarmac, the fourth group of 30 people to solve the mine, and the fifth group of 80 people to take over the groups.

After assigning the combat mission, Jack looked at a patrol that had just walked away and gave the order to start the operation.

The battle groups quickly passed through the minefields in the open field, and then divided into five lines and headed straight for their respective combat objectives. Ten minutes later, all five teams returned with the message that they had safely arrived at the intended area, and Jack immediately sent a signal for a general attack to the fleet hidden in the distance.

On the planet where the fleet is hidden, thousands of air and space fighters that have been waiting for a long time take off into the sky, like a group of pterodactyls in the dark night, and swoop straight towards Baccarra.

The fleet's air and space fighters have already taken off, and there are still about twenty minutes to reach Bakka, so these five combat teams must solve the guards everywhere within these twenty minutes.

Jack led thirty mecha warriors straight to the smelter, the rest is not important, the first thing that needs to be controlled is the equipment and technicians of the smelter. Jack led thirty mecha warriors to the vicinity of the smelter, unloaded the mecha, wore a special color-changing camouflage suit that could blend in with the surrounding environment, and only carried a laser pistol and dagger, and sneaked into the smelter.

Those four large mech fortresses are the biggest obstacle, if they are not handled well, once the fortress mechs fire, then there is only one way to attack.

Jack chose the northeast corner of the smelter as the breakthrough, and everyone prostrate on the ground and looked at the giant mecha fortress in the distance, which occupied a circle of more than thirty square meters and a height of more than ten meters, like a huge round mushroom. It has sixteen anti-aircraft missiles, four large anti-aircraft laser artillery, and as many as 20 small rapid-fire laser self-defense artillery.

At this time, the guards inside the mecha fortress were smoking cigarettes, probably because of the hot weather and smoking, the hatch of the mecha was wide open, which was a good opportunity.

A reconnaissance bionic fly released transmitted back the image in the mecha fortress, which was similar to what Jack and the others had guessed, there were a total of twenty-four enemies in the mecha fortress, and the enemies were so densely gathered that it would definitely not work to attack with bionic insects. Because as long as there is only one enemy left, once the artillery is triggered, it will startle the snake and make the infiltration operation useless, and in the end it can only turn into a strong attack.

Jack made the group wait where they were, and he slowly crawled from the blind spot of the mecha fortress to get closer, the glare of the searchlight sweeping overhead, interrupting Jack's movement several times. The soldiers behind him all sweated for Jack, pointed the laser gun in his hand at the fort, and as soon as the enemy moved, he immediately opened fire to cover the general's withdrawal. Jack finally climbed under the iron fence on the periphery, Jack used his mechanical arm to cut a one-foot-square hole in the iron fence, and then carefully drilled in, crawling forward for more than twenty meters, and finally approached the giant fortress.

Jack stood up with his back pressed against the cold walls of the mech fortress. The guards in the fortress were chatting with each other, unaware of the danger coming. Jack no longer hesitated, took out three powerful anesthetic grenades from his backpack, opened the safety pin and followed the spiral ladder for two or three steps to the mecha fortress more than ten meters high, threw the tranquilizer bullet into the fortress, and then slammed the hatch shut.

Under the action of a high concentration of anesthetic, there was no reaction time of 0.01 second, and there was no movement in the fortress immediately.

In order to buy time to settle the battle as soon as possible, Jack divided the thirty mech warriors into ten battle teams, and each group of three people acted separately. Under the cover of night, the teams immediately dispersed and penetrated into the depth of the smelter.

Jack led three warriors through a warehouse area quickly, hid in a corner to observe the movement outside, the two warriors took out more than 20 attacking bionic poisonous bees from their backpacks, this poisonous bee has the function of identifying friend and foe, and the poisonous bee carries ten anesthetic poison needles in its body, which can approach the enemy unconsciously and attack the enemy at close range.

More than 20 bionic attack bees were released, automatically looking for and identifying targets. A minute later, two mobile guards appeared on the control display, and the attacking bionic bee immediately flew automatically towards the two guards, and when they were a few meters away from the enemy, several tiny poisonous needles that could not be seen by the naked eye shot out of the body of the bionic bee, and immediately the two guards didn't even say a word, and fell to the ground softly.

Jack secretly praised, what a weapon for assassination and sneak attack.

One by one, the enemies were silently killed by the bionic poisonous bees, and in less than two minutes, Jack's group took down three waves of mobile sentry posts.
