Liu Yu, who was in the sea urchin base at the junction of the rock and the underground sea, didn't know that she had tentatively attacked the resource gathering pipeline of the student union group here, and there was a Sakuragi set below who watched her movements. Although Sakuragi's base is not in the completion form stage now, his main focus is on the robot team, so as long as he has the intention to hide, the sea urchin base is also difficult to find.

After approaching the position of about two hundred meters of the resource collection pipeline, Liu Yu found a junior reconnaissance robot patrolling around the pipeline, this distance is already the best attack distance for the sea urchin base, Liu Yu is too lazy to hide his whereabouts, without saying a word, a laser beam is hitting the resource collection pipeline, and the route of the attack also covers the primary reconnaissance robot by the way.

Liu Yu can be said to know more about the attack ability of the sea urchin base than Li Chen, the designer and maker, when Li Chen patted his ass and left as soon as he built this base, the attack system behind it was equal to Liu Yu's test for him, or the kind of test that was a painful and bloody game.

Originally, it was just a tentative attack on the resource gathering pipeline, and Liu Yu didn't concentrate all his energy on one point of the sea urchin base, just an ordinary blow. But with such a blow, the primary reconnaissance robot that was blocked in front of the resource collection pipeline was directly pierced by the molten hole like a piece of paper, and it didn't even take a second to do so.

However, to Liu Yu's surprise, it was this kind of attack that only left a wisp of white smoke on the resource collection pipeline, which could not help but surprise Liu Yu, it stands to reason that at this stage of the game, this level of attack from the sea urchin base was enough to penetrate ordinary defensive barriers, but this time even the skin of a bare pipe was not broken.

"Huh! This Wang Xuanling can! Liu Yu said to the sisters behind him.

"He's a tortoise, and it's not surprising that he only dares to show his head when he hides in the back of the back." 、

"Hmph, break his turtle shell today!"

Liu Yu didn't want to waste time with the student council here, this level of defense estimated that the student council would spend all their energy and time on this in the early stage, but they also underestimated the sea urchin base and her Liu Yu's speed.

Liu Yu began to adjust the attack pattern of the sea urchin base, and the protective shields that were originally covered on the perimeter began to converge towards the sea urchin base in the direction of the resource gathering pipeline. The fiery red light illuminated a large area of the originally pitch-black underground sea, and where the light shone, the reconnaissance robots of the student union quickly rushed to the resource collection port on the seabed, of course the student union knew that the sea urchin base was going to be real, they were worried that the robot would lose a lot in the periphery, and they did not dare to open the mouth around the pipeline to let the robot return, so they could only recover it from the pipeline mouth on the bottom of the sea, where the protection level was higher They were not afraid of the attack of the sea urchin base.

In the shadows where the light does not shine, a pair of robots that are slightly different from the primary reconnaissance robots also took this opportunity to pour into the resource gathering pipeline, and now everyone in the student council is focusing on the sea urchin base that is gathering energy, and the three teams have three kinds of reconnaissance robots, and now they are mixed into a small team of robots that are not too different from their robots, and there is no error in identifying the signal, so naturally it did not attract their attention.

After this team of robots successfully entered the resource gathering pipeline, the people in the Sakuragi group also high-fived each other happily, and the first step of their plan has been successful! The group of robots that now entered the resource gathering pipeline went all the way up the pipeline, directly towards the lair of the student union joint base.

At the same time, Sakuragi did not give up on the operation of the other two teams of robots, and while the contestants of the student council were focused on attacking their sea urchin base, the other two robot teams of Sakuragi set had also accelerated their pace and successfully arrived at the predetermined location.

However, Sakuragi has changed his plans, and the two teams of robots that were originally used to interfere with the students' council's vision are now on a more important mission, and he believes that his robot team can do more with Yanagi's interference.

Liu Yu didn't know that there was a group around here that was fighting the idea of the student union, but even if she knew, she wouldn't care, she was such a person who would not be disturbed by other things for the time being if she had a set goal, and as long as this unexpected event did not affect her original plan, she would not change.

The sea urchin base that has been charged is like a small sun in the underground sea, the crimson light and high-intensity energy radiation have clearly told all the contestants in the vicinity that Liu Yu is here with the sea urchin base, if the protection system of the joint base of the student union can't stop her attack, then it is estimated that no one can stop it.

"III.

Two

One! Attack! With Liu Yu's order, a dazzling speed of light directly bombarded the resource collection pipeline of the student union, "Boom! This attack was originally only an attack of an energy weapon, but now it seems that it is like a kinetic energy weapon that violently shakes the impact of the resource gathering pipeline.

The swarms of robots in the pipeline collided uncontrollably back and forth in this violent shock, and even the robot team of the fourth group hidden in it collided back and forth in the pipeline uncontrollably.

"Damn, don't you want to be so perverted in the sea urchin base!?" Sakuragi Ji originally just regarded the sea urchin base as an ordinary intermediate base, but now it seems that the attack ability of the sea urchin base is completely at the level of the advanced base, and this resource collection pipeline of the student union may not last long.

"Hey, boss, the turtle shell of the student council can't hold up this time!"

"Phew! Call sir! ”

......

You must know that this attack on the sea urchin base is not a kinetic energy attack, the violent shock just now is just a side effect, and the real key attack has been applied to the resource gathering pipeline!

The bright and piercing white pillar of light had burned a large hole about twenty centimeters thick on the resource gathering pipeline like a bayonet, and the diameter and depth of the large hole were still expanding at an accelerated pace, but the people of the student council did not even do anything to stop it, and let the energy weapons of the sea urchin base attack their pipes.

It's not that the people of the Student Union United Squad don't want to go out and stop the attack of the Sea Urchin Base, it's that they simply don't have the ability to stop the attack of the Sea Urchin Base now. Their main forces are used to develop defense systems and fortifications, and these defense systems are definitely not likely to cover the location of underground resource gathering pipelines that are hundreds of meters away from the base camp of the base, so they can only let the Sea Urchin base destroy it now, just hoping that the impact of this destruction will be as small as possible.

Of course, it is impossible to make this destruction have no impact, and the most important locations of their joint bases are now the base itself, the joint base station in the center of the three bases, and the last one is the pipe mouth of the resource gathering pipeline on the seabed.

The resources consumed by the construction of the pipe mouth of this collection pipeline are enough to make the student union joint base suffer for a while, and the reason why they can develop rapidly is completely dependent on the efficiency of the collection system of this pipe mouth, and now under this level of attack, it is impossible for them to recover the pipe mouth.

In fact, Sakuragi's initial goal was just the pipe mouth of this resource collection pipeline, and now with Liu Yu's help, he has a more important goal......
