The envoys of the four seventh-level civilizations left, but the shock brought by the four seventh-level civilizations to the living beings present was far from being eliminated.

In the universe, black holes are the most mysterious realm, but the four seventh-level texts can use black holes at will.

This technology alone is enough to make all the people present feel terrified.

Su Han let out a long sigh of relief in his heart when he saw that the envoys of the four seventh-level civilizations had finally disappeared.

This tone is not only an invitation to perfectly solve the four seventh-level civilizations, but also a blessing that the four seventh-level civilizations have not discovered that mysterious piece of metal.

The metal fragment obtained by the Dragon Kingdom has the effect of disturbing the surrounding magnetic field, so the Dragon Kingdom has not had a proper way to preserve it, and has been throwing it in the depths of a certain sea area.

Although that mysterious metal fragment has the effect of shielding all electronic components, in case the four major seventh-level civilizations search on Long Yuan Star on a whim, it is very likely to find that mysterious metal fragment.

Just now, Su Han thought of the existence of that mysterious metal fragment, and a cold sweat flowed.

Don't look at the four major seventh-level civilizations who are polite to themselves now, if they find out that Long Yuanxing has the piece of metal they need, they will definitely turn their faces in an instant.

No way!

That mysterious piece of metal must never be used again.

Even if you really want to use it, you must kill all the 'insiders'.

Once the four seventh-level civilizations learned that Long Yuanxing would not hand over a piece of metal if they got it, they would definitely have some kind of suspicion towards Long Yuanxing.

Although he had already made a decision in his heart, because there were civilizations from other beings on Longyuan Star, Su Han did not take immediate action.

Two days later, the number of civilizations that came to visit Longyuan Star gradually decreased.

A week later, creatures from other civilizations also left Longyuan Star completely.

After there were no more creatures of other civilizations on Longyuan Star, Su Han immediately pulled Liang Shuang to a certain sea area.

After Liang Shuang's confirmation, Su Han finally determined that the mysterious metal fragment was hidden under this sea area.

After Su Han's explanation, Liang Shuang also knew that the mysterious metal fragment was a time bomb for the Dragon Kingdom.

Now that he found that Su Han had pulled him here, Liang Shuang couldn't help but ask out loud, "Team Leader Su, what are you going to do with this mysterious metal fragment?" ”

Now, all the cosmic civilizations are looking for metal fragments from the eighth-level civilization, and once a civilization discovers that there is such a metal fragment on Longyuan Star, it will definitely bring a catastrophe to Longyuan Star.

In this case, secretly handing over this mysterious metal fragment to any of the seven civilizations of the four universes was the most suitable choice.

Because in this way, not only can the disaster of Longyuan Star be avoided, but also Longyuan Star can be fully supported by a seventh-level civilization in the universe.

Hearing Liang Shuang's question, Su Han turned his head slightly and asked rhetorically, "Liang Shuang, do you think we should hand over this mysterious metal fragment to one of the seventh-level civilizations of the four universes?" ”

Hearing this, the grain nodded instinctively.

Seeing this, a gleam flashed in Su Han's eyes: "Actually, at the beginning, I also had the idea of secretly handing over this piece of metal to one of the seventh-level civilizations of the four universes, but a week ago, after seeing the strength of the four major universe civilizations, I changed my mind. ”

"Give this mysterious metal fragment to the seventh-level civilization of the four universes, no matter how much effort we put in, our Longyuan Star will at most grow into the existence of the seventh-level civilization of the universe, but if we can find the other three mysterious metal fragments, our Longyuanxing may become the legendary eighth-level civilization."

"At that time, our Longyuan Star will stand at the pinnacle of the universe, eternal and immortal!"

Hiss......

When Liang Shuang learned that Su Han had such an idea, he couldn't help but gasp.

That's the legendary eighth-level civilization!

Long Yuanxing is now only at the peak of the third-level civilization of the universe at best, and I don't know how many levels are still in the middle.

Looking at Liang Shuang's ghostly look, Su Han secretly shook his head.

I was not surprised when such a thought first came to my mind.

But after thinking about it, he had Murphy's memory in his mind, as long as he had enough resources, it was only a matter of time before Long Yuanxing became a seventh-level civilization in the universe.

Since Long Yuanxing can become a seventh-level civilization in the universe, why not try to impact the legendary eighth-level civilization.

And this mysterious metal fragment is from an eighth-level civilization, and it contains a shocking secret.

If Long Yuanxing wanted to impact the eighth-level civilization, he couldn't hand it over.

Of course, for such an important matter, Su Han naturally would not make an assertion.

A few days ago, Su Han once informed the No. 1 boss of his idea.

After a brief shock, the No. 1 boss expressed unconditional support for Su Han.

It is precisely because of the support of the No. 1 boss that Su Han's determination to impact the eighth-level civilization has been strengthened.

I don't know how long it took, Liang Shuang finally recovered from the shock, and asked, "Team Leader Su, I see you mean that you don't plan to hand over this piece of metal to the four seventh-level civilizations, so what are you going to do with it?" ”

When Su Han heard this, he pointed to the sea area in front of him, squinted his eyes and said, "If I'm not mistaken, there are a lot of prehistoric sea creatures in this ocean, we can completely put that mysterious piece of metal into the stomach of one of the marine prehistoric creatures, and install a tracker on that marine prehistoric creature." ”

When Liang Shuang heard this idea, his eyes immediately lit up.

Oh, yes!

It was the safest way to put that mysterious piece of metal among the prehistoric creatures of the sea.

As long as that prehistoric sea creature does not leave Longyuan Star, then that mysterious piece of metal will always belong to Longyuan Star.

Although this will make it impossible for the dragon kingdom to study this mysterious metal fragment for the time being, it will also eliminate all dangers.

Unless other civilizations give Longyuan Star a massacre and slaughter all the lives on Longyuan Star.

Otherwise, they would not have thought that a certain prehistoric creature of the sea on Longyuan Star actually had a mysterious metal fragment hidden in its stomach.

Thinking of this, Liang Shuang didn't need Su Han's order, and directly led someone to capture a dragon.

After a brief treatment, the mysterious piece of metal was stuffed into the dragon's belly and a tracker was attached to it.

After doing all this, Liang Shuang clapped his hands and said with a smile: "Team Leader Su, it's okay now, let's no longer have to worry about that mysterious metal fragment being discovered by other civilizations." ”

But what Liang Shuang didn't expect was that Su Han shook his head and said in a deep voice: "Just like this, it's not enough!" ”
