Assessment requirements: 72 hours in chaos star domain. Destroy at least ten warships of the same rank or above. The longer you persist, the more points you get.

This is a team task, which should have been evaluated by everyone. But they are a group. Considering their integrity, the college has given the task of the team.

Is it hard to live in chaos for 72 hours? It's hard. This star is the most difficult experience place for small and medium-sized warships. Even a commander with a very sophisticated command of warships can easily overturn accidentally here. Because no one knows what kind of opponent they will encounter in the chaos universe.

There are only two kinds of people who can come here to practice. One is to have great confidence in the control ability of your warship. The other is to plunder resources.

Those who plunder resources usually get some rare metals and run away. And those who practice manipulation don't care about that, just to practice their own abilities.

There's a ranking for the chaos galaxy. The number one warship, the survival time here is 208 hours.

It's also a meteor class attack ship, but it's the area he entered with three supply ships. With its own strong strength, it took such a long time to protect its supply ship as much as possible while killing the opponent.

It seems that the gap between 72 hours and 208 hours is quite large.

But actually, LAN Xuanyu's warships have no supplies. Under normal circumstances, the energy of warships can fly in the universe for a month. Even longer. But this is without fighting.

Once in the combat state, both the shield and attack energy output will consume a lot of warship energy.

Why does a fleet need a huge Mothership as its core? It's because there's enough energy in the mothership.

They were even required to carry no more than three tons of rare metals as energy. This fully limits the duration of their fighting.

In this case, it is not easy to persist in 72 hours in the chaos star region, and every point of energy must be accurately calculated.

What's more, they are required to defeat ten warships. It is necessary to fight, and the energy consumption in the fight can be imagined.

Therefore, they not only want to fight, but also plunder the rare metals that can be used as energy, so that they can really persist.

The difficulty of the task is conceivable. Even the meteor class attack ships officially in service by the Federal Military can only be achieved by the most ace fleet.

LAN Xuanyu sat in the main control position of the warship and silently received various data summaries.

"Twenty one minutes to reach the chaos galaxy." Ding zhuohan's report came.

"OK. Keep going at a constant speed. " Uniform speed is the most energy-saving.

They have been here many times. They are familiar with the situation here. But this time, it's different. Because they have no chance of failure.

This is a real battle to assess them, only once. Because in reality, failure once means death.

LAN Xuanyu felt the change of the outside world calmly, and his mental power was completely connected with the warship. At this moment, everyone is absorbed. Before the warship takes off, LAN Xuanyu tells everyone to forget the gains and losses and go all out. All the rest is to him.

In the Star Wars experimental class, everyone has no hesitation about LAN Xuanyu's trust. Because he led people to create miracles again and again, this time is no exception.

Twenty one minutes passed, and they were once again on the edge of the chaotic galaxy.

Still in no hurry to enter, the warships began to slowly cruise around the chaos Galaxy periphery, looking for the best entry point.

The 72 hour countdown that appears in the top right corner of the screen doesn't start. This countdown will only begin when they actually enter the chaos universe.

Today's chaotic Galaxy interior is quiet, with no explosions or rumblings.

They were very patient, and the cruise time soon reached half an hour.

Cruising doesn't consume much energy, but the longer the driving time is, the greater the mental consumption of students is. The continuous 72 hours of operation without sleep does not require a high level of physical fitness. But we should always concentrate on the control, which requires a lot of energy.

At this time, Ding zhuohan's voice suddenly sounded, "there is a slight energy fluctuation in the front right, and it is suspected that there is an invisible warship approaching."

There was no movement inside, but there was movement outside.

"The ship is silent." LAN Xuanyu did not hesitate to give the order.

His voice can be heard not only by his friends, but also by the teachers outside.

Hearing the words "Silence" of the whole ship, Sakura almost jumped up. This assessment has not officially started yet. How did LAN Xuanyu take risks?It's not easy to detect the silence of the whole ship, but the problem is that once it enters the silence state, it will take time for the warship to start again! In case of encountering the opponent's undifferentiated cover attack, it will be found out from the void. They're in big trouble. It's hard to fight back.

But what LAN Xuanyu ordered was so decisive that he did not hesitate.

The warship quickly entered a state of silence, all energy systems were shut down, and only the stealth system remained. In this case, it is very difficult to be found.

They have cooperated very skillfully. When LAN Xuanyu gives the order of silence, his classmates will understand what he is going to do.

They are waiting for the same invisible warship to show its birth. When the other party is about to enter the chaos star domain, it is bound to remove the invisibility.

There is no mistake in judgment, and luck is on their side as well.

A few minutes later, a warship quietly entered the chaos star field, and then revealed itself.

"Charge the main gun. The warship starts. " LAN Xuanyu immediately gave the order.

When the warship enters the chaos star domain, not only the warship's stealth effect is invalid, but also all kinds of detection radars will be interfered by the influence of the star domain magnetic field. That's why LAN Xuanyu and others need to wait for the best time to enter chaos. Once entering, it is the most dangerous situation to be attacked in the process of entering.

It's really hard to meet such an opportunity. The chaos Star area is very vast. It's absolutely a once-in-a-lifetime opportunity to encounter a warship entering just when cruising outside. From this point of view, LAN Xuanyu's luck in the graduation exam is absolutely good.

The charge of the main gun will naturally send out strong energy fluctuations, but that warship is just beginning to enter the chaos star domain, which is the weakest time for all aspects of exploration.

In the dark space, under the command of LAN Xuanyu, suddenly a dazzling light came on, almost chasing after the bottom of the previous warship, and pounding hard at its tail.

That warship dare to enter the chaos star domain, naturally, it has no weak ability, but there is no way at this time. If it can't dodge, it will be hit hard by LAN Xuanyu's main gun.

In the fierce roar, the protective cover behind the warship exploded in the strong light and rain, and the protective cover suddenly became unreal. This is a real bombardment by the main gun of the warship, without any dodge or resistance.

"Speed up!" LAN Xuanyu issued the order to fully open the thruster. At this time, he could not love the energy reserve, because once he and the other party entered the entanglement state, they would consume energy in a short time, which is absolutely less than the consumption of quick battle.
