In fact, there is nothing to think about at all, and the answer is as obvious as a fly on a bald head.

The number of super-heavy elements in the republic's reserves is quite large, and there is no shortage of super-heavy elements for the time being. However, the consumption of super-heavy elements has always shown an increasing trend, although the vast majority of teleportation crystals are used in the military, but the increasing amount of use still weighs down the entire country.

Originally, I thought that grabbing the Poris pulsar would relieve some of the pressure, but after occupying it, I found that the crystal veins near the Poris pulsar were very barren, and for the Republic, that little reserve was only better than nothing, but it was only a little higher than the yield of artificial synthesis - artificial synthesis requires a lot of energy, and it is simply more than worth the loss.

In the short term, it will be difficult for the military's fleet to reach the farther neutron stars, so Betelgeuse is the last hope to find the veins of superheavy elements.

But the question now is, did the super heavy elements form when Betelgeuse exploded, if the super heavy elements were found, even if they smashed into half of the fleet, Ye Fei would not frown, but what if nothing was found?

With an extremely tangled mood, Ye Fei gave the order to break into the nebula, and an air-supremacy firepower ship slowly flew out of the outer armor of the mothership's side hole, and then suddenly accelerated into the nebula.

And then...... No more, after the air supremacy fireship penetrated to a certain distance, the interference of the nebula shielded the quantum communication between the battleship and the air supremacy fireship, and in just a few minutes, the remote-controlled air supremacy fireship completely disappeared.

At this moment, not only Ye Fei was dumbfounded. Even Xie Guohui was stunned, and he couldn't say half a word of pleading.

It's enough for his old face to be sold once, is it possible to reduce the price and get a big reward?

Ye Fei thought about it again and again, and finally made up his mind to continue the plan.

However, the battleship that entered the nebula was no longer remotely controlled, but a return time was set by programming, and the return time of the second air-controlled fireship flying into the nebula was ten minutes.

The battleship entered the nebula along the way, and after a few minutes the battleship lost contact...... The next ten minutes were as long as a dozen centuries, and when the news of the establishment of communication between the air supremacy and the mother ship again came out, the entire fleet erupted into crazy cheers as if it had won a hard victory.

Ye Fei immediately ordered all the warships to participate. Each has a different return time. And use the magnetic sensor to remotely locate the battleship entering the nebula-At this moment, Ye Fei hated the limited detection range of the magnetic sensor.

In addition to the detection fleet that had been sent to the front like death, a large number of reconnaissance satellites were left behind the positions that had already flown behind the battleship.

Nebulae have strong interference with communication systems. But Cheng Dù was far from being as close as the shock wave, and communication was still cut off. There is no problem with communication within a minimum of a few optical minutes. By relaying signals between satellites, long-distance communication can be realized.

As the fleet began to move deeper and deeper into the nebula, it began to move deeper and deeper into the nebula. In order to improve efficiency, Ye Fei even used several warships to set off at the same time, but the method of different return times was used to improve efficiency, and in less than an hour, the fleet was half a light-year deep into the nebula.

It seemed that good luck had come to an end, a way-finding assault ship failed to return within the scheduled time, and the cautious Ye Fei immediately ordered the fleet to stop advancing.

After studying the number of missing battleships, the fleet advanced again for a distance of less than ten minutes from the location of the missing assault ships, and each ship turned on the force field under the coordination of the Xinyuan and moved slowly, and at the forefront of the fleet were more than a dozen remote-controlled warships.

In contrast, the effective range of the radar is much closer, and even if the power is turned to the maximum, the effective control distance is only about seven light seconds.

The fleet advanced with extreme caution, and it was not until half an hour later that the radar of an air-dominated fireship detected a huge object with a diameter of no less than 100 kilometers directly in front of it.

Ye Fei didn't have the heart to study what that thing was, so he directly ordered the fleet to open fire, and several planetary burst bombs hit it, blasting the small celestial body blocking the way into pieces.

Ye Fei was more cautious in the next trip, but at most half a light year, the fleet would definitely bump into something, and he would have to take a lot of effort to move on.

However, it wasn't just that there was an obstacle in front of them, but things would float out from the side without warning, and several battleships were negligent in their precautions, and they were actually smashed by small celestial bodies and destroyed the outermost layer of armor.

The more troublesome you fly deeper into the nebula, the higher the chance of hitting an obstacle, and it's simply difficult.

By the time Betelgeuse was still a light year away, the radar was full of large and small celestial body reflection waves, and Ye Fei felt that the fleet could no longer use the speed of light to continue moving.

But having come to this point, he was really unwilling to give up, he gritted his teeth and simply used magnetic missiles to open the way.

Just a few seconds after the first wave of magnetic missiles were launched, they exploded in half in front of the fleet. Maybe the material density of the nebula is too high, and the concentrated explosion of the nuclear bomb actually pushed the nearby nebula a little away!

This result was so surprising that Ye Fei suddenly thought of a good idea, and immediately ordered the fleet to stop advancing and start loading gravity shells for the gravity cannons.

A few minutes later, more than a dozen gravity shells were slowly discharged, and shortly after leaving the battleship, the artificial gravity device inside the shells began to work, attracting nearby materials...... The massive matter is certainly not absorbed, but the nebula that spreads everywhere is no problem at all.

After a wave of gravity shells was over, everyone finally saw the situation ahead.

It can only be said that the situation is worse than imagined, and the number of small objects in front of us is far greater than everyone thinks, almost indistinguishable from the asteroid belt - the chance of collision when passing through the asteroid belt in a conventional way is pitiful, but it is difficult to say that it is difficult to pass through guò at the speed of light.

The fleet was almost trapped, and at this point, Ye Fei decisively ordered the assault ships with the remote control force field full open to enter the superluminal speed and crash through the obstacles in front.

He had already prepared for the loss of all the assault ships, but after nearly half of the more than twenty assault ships that were on the rampage, they actually succeeded in opening up a safe line!

After a long time, Ye Fei and the others knew that the fleet had actually accidentally intruded into a material-dense airspace, and if it had been changed to another direction, it would not have encountered such trouble at all.

It's a pity that it was too late to regret it at that time.

The passage opened by the assault ship led directly to the outside of this material-dense area, and next, the fleet actually traveled the distance of the last light year! (To be continued......)
