Zhang Hao spread his hands: "Okay, it seems that I am right to bring you, at least we are not affected by radiation." ”

Sometimes, people always have an advantage.

Zhang Hao made a light and tough spell material, everyone could easily stand on it, Gary was responsible for making the board levitate with everyone, and Olivia used wind spells to push forward.

It can't be helped.

There is not even active energy here, Olivia casts any spells and awakening abilities on her own, Zhang Hao doesn't want to increase her consumption in this unknown environment.

With this kind of operation, Olivia's own energy can keep the board flying for a day, after all, she only needs to exert force forward, and she doesn't have to bear the weight of everyone.

There are also various means of transportation in the space tower, but almost all of them need to consume mental power and active energy.

Here Zhang Hao and Olivia are official primordial mages, and it is better for everyone to retain their spiritual power.

But soon, Zhang Hao's mood took a 180-degree turn.

Olivia's speed of pushing the board was not fast, and she deliberately flew past the metal wreckage so that Zhang Hao could collect the wreckage.

Athena's reminder soon came: "Unknown alloy discovered, unknown high-grade technology discovered." ”

This makes Zhang Hao very happy, is this a world of science and technology?

After a while, after collecting a large pile of wreckage, Athena suddenly issued a reminder that surprised Zhang Hao: "Unknown atomic reactor technology has been discovered, pay attention, the atomic reactor can be used as an auxiliary energy source for the space tower." ”

Zhang Hao was overjoyed, and couldn't help but let out a "" in his mouth.

Everyone looked at him, but Zhang Hao just said to Olivia: "Try to pass near the large wreckage, there are good things." He wants to make further sure that this atomic reactor technology is not universal.

If it's only a small amount, he may not be able to get his hands on it easily.

Next, Athena's reminders kept coming, and Zhang Hao was sure of one thing: the atomic reactor technology here was definitely popular, and unlike the power stations of Aqua Blue Star and Space 3, which were only fixed on the ground, they all existed in those mechanical wreckage.

The space tower is not limited to dark energy reactors, but even if the entire Great Xia generates electricity to charge it, the efficiency is only several times faster than that of dark energy reactors.

Can Zhang Hao input all the electricity of the whole Great Xia into the space tower? Of course not.

Not to mention all the power generation, even if it is one-tenth, Daxia is estimated to have a headache.

Daxia has a large population, and the power gap has always been not small.

And it's not impossible for him to get the atomic reactor technology from Aqua Blue, but let him get the raw materials himself? Maybe the raw materials he gets a year are not enough for him to deliver once.

But Athena's statement at the moment that the atomic reactor can be used as an auxiliary energy source for space towers means that the technology is not inefficient.

Zhang Hao has always been very helpless, that is, the charging speed of the space tower takes half a month at a time.

Although this charge speed is already fast, wouldn't it be better to be faster? Energy replenishment is fast, which is a huge improvement in the defense and security of the space tower.

However, after collecting a large number of metal wreckage, Athena reminded: "With these wreckage alone, I can't restore the technology, it's better for you to try to find the complete information of the technology, and it is better to get the finished product directly." ”

Zhang Hao thought about it for a while, and said to Olivia and Dakota: "Have you found anything?" Like humans? ”

It is said to be human because human bodies have been found in certain wreckage.

And some of them are still relatively intact, after Athena tested in the space tower, she found that the humans here are not much different from the humans in the previous dimensions, and even the appearance is the same.

Along the way, no traces of human activity were found, not even buildings, and the only signs of civilization that Athena had detected before were metal wreckage.

Zhang Hao thought about it for a while, and simply sent the other people back to the Space Tower, leaving only Dakota and Olivia to accompany him to continue the search.

Dakota is a spiritual boss who can feel all kinds of abnormal mental power fluctuations.

Olivia's wind spell Listening can hear sounds far away.

As the sky darkened, Zhang Hao looked at Olivia and Dakota, both of whom shook their heads.

Zhang Hao could only give up, and the three of them also returned to the space tower.

In this completely unfamiliar environment, and with highly developed technology, it is safer to go back to the space tower to rest.

The others were all reading and cultivating in the space tower, and when they saw them come in, they also cast concerned glances.

Zhang Hao spread his hands: "Everyone can do their own activities today, and I didn't find anything worth exploring today." Well, let's eat first. ”

A group of people have eaten, they disperse, they learn, they are lazy.

Zhang Hao asked Athena to project a few copies of the information found in those metal wreckage, and Olivia and Dakota, Black Beanding got together with him, and followed to see if there was anything worth noting.

After all, Athena is just an artificial intelligence, and some people can detect something wrong, but she may not be able to find it.

A few people looked at it, and probably formed a consensus.

There's certainly a lot of technology here, but there's no human being here. The wreckage appears to have been scattered here after an accidental crash, for unknown reasons.

But judging by the wreckage and the contents within, it is likely that the wreckage was part of some large ordnance.

Overall, this is a world worth digging into, even if it's only for atomic reactor technology, Zhang Hao has to explore it well.

The previous events in Space 2 and Space 3 have basically come to an end, so the exploration of Space 4 is expected to take at least a month, and everyone has plenty of time.

After a night's rest, the next day was still Zhang Hao, Olivia, and Dakota exploring outside, and the others stayed in the tower.

There was still nothing to be found during the day, even if Zhang Hao no longer let Olivia take a detour, but went straight as fast as possible, he couldn't find any trace of humans.

It's just that after leaving the area with severe radiation, various plants have appeared one after another, but they are not many and have all kinds of strange shapes.

There are also many animals and insects, proving that this planet is not a completely dead place.

Until dusk, the blood-red sunset hung in the sky, and Olivia's face suddenly moved: "There is a discovery." ”

Zhang Hao and Dakota were both in good spirits.

Olivia closed her eyes for a moment, opened her eyes and said, "It's definitely the sound of some kind of machine running, the frequency is very even, and it is relatively stable, and it is always working." ”

This means that only human beings, or at least intelligent beings, can be able to do so.

Olivia picked up speed again, heading towards where the sound had come from.

Olivia, who used the listening technique, could even hear sounds from tens of kilometers away with the wind, so the three of them flew for almost half an hour before finally discovering the machine at a distance of nearly a hundred kilometers.
