After learning about the situation that the Dragon Kingdom was facing now, Zhao Rongsheng didn't say a word, and went into the laboratory again to start the experiment.

This trial lasted for a week.

During this week, Zhao Rongsheng ate, drank, and lazard all in the laboratory.

During this period, Su Han was not idle.

He was often seen in the lab.

Whenever Zhao Rongsheng's team encounters any problems, Su Han will use the information he has obtained to help solve them as much as possible.

Regarding the problems on the mecha, one by one was solved.

As for the synthesis materials of mechas, there has never been a perfect solution.

Of course, it's not that Murphy's 'information' is insufficient.

It's because the materials needed to make the mecha of the Third Universe Civilization can't be found on Blue Star at all.

In this case, Su Han used the known information and began to synthesize the materials in the Blue Star.

Although this will reduce the balance and combat effectiveness of the mech.

But now it's the only way!

On this day, Su Han, as usual, began to synthesize the materials needed for the mecha.

Maybe it's because of the failures too many times.

Even Su Han didn't have too many illusions about this synthesis.

"Basalt, steel stone, Longyan rock steel ......"

As a series of materials were added to the special container, Su Han quietly waited for the result.

Five minutes later, an alarm sounded in the specially made container.

There is no doubt that this experiment failed again!

This made Su Han feel very helpless!

During this time, he found almost all the materials on the Blue Star.

However, due to the instability of these materials, there is no way to synthesize the materials needed for mechas.

Even Su Han himself didn't remember that this was already the first time he had failed.

On the side, Zhao Rongsheng saw this scene, and said in a somewhat low tone: "Su Han, it's been a week, but there has been no progress on the matter of mecha materials, otherwise ......"

Although Zhao Rongsheng didn't finish speaking, Su Han knew what he meant.

There is no progress in the matter of mecha materials, and another civilization will invade Blue Star at any time.

In this case, abandoning the mecha and building another defensive weapon is the best way to do it at the moment.

In Su Han's mind, there was also the technology of other civilizations.

However, these technologies must be supported by a strong level of science.

Even if Su Han knew the principles of these technologies, with Blue Star's current resources and technology, it was impossible to create the technology of other civilizations in a short period of time.

Thinking of this, Su Han couldn't help but shake his head: "Teacher, we don't know if the conventional weapons on the Blue Star are effective against the creatures of other civilizations, if we put a lot of energy into the manufacture of conventional weapons, and we can't cause harm to the creatures of that civilization at that time, then those weapons will turn into a pile of scrap metal." ”

Zhao Rongsheng did not know the specific situation of other civilizations in the universe.

But Su Han knew it.

He knew that the creatures of other civilizations in the universe were not only advanced in science and technology, but even their physical fitness far surpassed that of the people of the Dragon Kingdom.

Even, some cosmic civilizations have abandoned their flesh and blood to build a steel body for themselves.

This kind of body is enough to cope with the attack of conventional weapons.

Finding that Su Han had vetoed his proposal, Zhao Rongsheng sighed and restarted the experiment.

As for Su Han, he didn't immediately put himself into the experiment, but was thinking about what went wrong.

The order in which the materials were added and the various ratios were repeatedly explored, but there was not a single experiment.

Wait a minute......

Could it be that when it is synthesized, there is a problem in other links?

Su Han closed his eyes and began to simulate the entire experiment in his mind.

Five minutes later, Su Han opened his eyes again.

Su Han has always used human drinking water as a catalyst for this experiment.

But I forgot that seawater contains a lot of energy and substances.

Perhaps, these energy substances were the key to the success of this experiment.

Thinking of this, Su Han no longer hesitated and directly started a new experiment.

This time, Su Han did not use human drinking water, but directly ordered people to fetch seawater.

All known materials are put down, and finally an appropriate amount of seawater is poured in.

To Su Han's surprise, there was no alarm sound in the specially made container this time.

This made Su Han more cautious while being pleasantly surprised.

As the process of material synthesis was completed one by one, Su Han was surprised to find that he had obtained a special material.

Not only does this material have great tolerance, but it also has amazing defense.

"It's done!"

As Su Han exclaimed, Zhao Rongsheng couldn't help but cast a puzzled look.

When he looked at the materials in Su Han's hand, he said with a shocked face: "This is the necessary material that the mecha needs. ”

Su Han didn't sell it, and nodded directly: "Teacher, if you want to synthesize this material, you must use seawater, because seawater contains energy substances in it. ”

Hearing Su Han say this, Zhao Rongsheng asked rhetorically: "It's not so much the seawater, it's not the energy substances contained in the seawater that made this experiment successful, if we extract the energy substances in the seawater and add it to the test, I don't know what the result will be?" ”

At first, Su Han was too happy because of the synthesis of materials, so he didn't think of this problem.

After Zhao Rongsheng's reminder, Su Han immediately reacted and ordered: "Quickly go to the experts of the biology group and ask for a bottle of nutrient solution mentioned from the ocean." ”

Ten minutes later, someone delivered a bottle of nutrient solution to Su Han's hands.

Su Han did not hesitate for a moment, and poured the nutrient solution into a container specially used to synthesize special materials.

This time, the purity of the synthesized material is far higher and better than that of the material synthesized with seawater.

At the moment, this material is simply not enough to make mechas.

Next, Su Han increased the progress of synthesizing materials, and began to frantically synthesize the materials needed to make mechas.

The problem of materials was solved.

Then the next step is to build the mech.

Because Su Han had in mind the core technology of this series of mechas.

So it's not that hard to make!

Three days later, Su Han finally created the first set of mecha in the Dragon Kingdom.

And Su Han also ordered this set of mecha to be a Shenwu mecha, and decided to test the Shenwu mecha three days later.

Su Han didn't know that during this time of their busy time.

A spaceship departs from the Siqin Empire, travels through major galaxies, and heads straight for the Blue Star.

Of course, because Blue Star is far away from the Siqin Empire, even if this spaceship is a product of a second-level civilization in the universe, it will take half a month to reach Blue Star.

By this time, the ship was already halfway there.

In other words, they will arrive at Blue Star in a week's time.
