Speaking of alloys, Chen Yi remembers that he had drawn one before, called Titan alloy manufacturing technology.

At this time, find this directly in the system backpack and read the introduction.

【This is a new alloy, characterized by toughness, lightness, and relatively simple production process. Once forged, it is extremely difficult to destroy. It is generally suitable for mecha shells, spacecraft shells and other projects. The defense depends on the thickness...】

As the reading introduction was introduced, Chen Yi's eyes became brighter and brighter.

These two technologies are put together.

It made Chen Yi think of a picture.

——Indestructible city.

Both of these are technologies that can be used for mass production, and the production cost is not high. Even if it cannot stop the impact and coverage of a tsunami, at least, hurricanes and earthquakes in the next few months should be able to block it.

That scale, existing cities cannot resist at all, and it is imminent to rebuild cities, or shelters, that they can resist.

Otherwise, if people are allowed to be exposed to bad weather, there will be only a dead end.

"Dingxiang, if you get these two technologies, simulate and calculate the feasibility." Chen Yi exchanged the technology through information storage and passed it to Dingxiang.

Then, let the lilac simulate the calculation.

This is a complex calculation project because many parameters are uncertain, such as the degree of earthquakes, hurricanes, and high-energy neutrinos also affect the parameters of air convection.

Even lilac can only make a lot of predictions.

Finally, a probability was obtained.

"The feasibility is between 46 and 85 percent." In the projection of the captain's room, a simulated picture of lilac appeared.

It was a city with a wall. The buildings in the city were extremely monotonous and connected into one piece. You can see that at the foot of the city, there was a huge foundation connected into one piece!

As the model begins to become transparent, it can be clearly seen that the entire city is a skeleton made of dense alloys.

Extend from foundation to every building.

This seems not a real city.

But a whole, indestructible industrial creation!

"Why is there such a big fluctuation in feasibility?" Chen Yi asked.

"The lack of data, coupled with it, I am not a top construction talent, and I cannot know the efficiency of mobilization and infrastructure." Dingxiang explained, "Besides, there is no accurate data on the scale of hurricanes and earthquakes at present."

"How are these two technologies at the same time?" Chen Yi asked again.

"From the perspective of this era, it belongs to the 'science fiction' level." Dingxiang directly showed Chen Yi some of the content contained in the technology. "The design concept of this building material takes into account the gravity and environmental factors of various planets. It should come from a civilization that has achieved large-scale interstellar colonization. The application of Titan alloy is also very widespread, with mecha shells, giant ship keels, and even spacecrafts. "

"This should be considered a complete black technology." Chen Yi exhaled, then frowned again, "Can it be produced with the production technology of this world?"

"It may not be possible to produce the best quality, but ordinary, or even inferior quality quality should be no problem." Dingxiang replied, "Captain, my calculations have included this factor together, otherwise, the highest feasibility should be approaching 100%.

Compared with the planets in the universe, those with worse environments.

Changes in the environment on earth can only be considered "moderate".

"Then." Chen Yi's expression became a little serious. He asked the last question, "What about the possibility of building an undersea city."

The entire continent will eventually be completely covered by sea water, and even after everything is calmed down, the parts that will be exposed are very sparse.

That should not be the mainland anymore.

It's an island.

Undersea city, if it is really feasible...

However, Dingxiang did not give the answer Chen Yi wanted.

"I'm afraid it won't work, captain." She gave the relevant pictures on the technical data directly. "The 'light' characteristics of this building material come from its unique 'window' structure, which allows it to stand on certain planets with high gravity. However, long-term soaking in water will not cause damage, but will allow water molecules to gradually penetrate into the building."

In other words, everything is good, it just doesn't block the water.

It won't be completely sealed either.

"So..." Chen Yi narrowed his eyes half-squinted.

Lightweight, easy to produce, strong resistance to strikes... It almost meets the survival needs of people in this world, but it is not waterproof.

"According to Dingxiang's speculation, such cities should have other supporting facilities in order to establish immigration areas in aliens." Dingxiang said, "For example, protective shields spread throughout the city are used to isolate toxic gases and establish micro-ecosystems."

She added a translucent protective barrier to the city model in front of her.

This is why I can barely be qualified to be an alien immigrant city.

But... I just didn't get such a technique.

No, technology is useless. With the industrial level of this world, this technology cannot be manufactured at all. It is necessary to draw equipment specially used to make large protective covers.

"I'll continue to draw a few times to see." Chen Yi glanced at his remaining points.

We must save some use. A transport aircraft like the one just now requires 200,000 points to buy one. Once the traffic road is really completely destroyed, it will definitely not be solved by dozens of aircraft.

Speaking of transportation, Chen Yi thought of the sea train technology he had drawn before.

If humans can really survive in a vast ocean.

Then this technology may play a huge role.

However, I have to live until then.

Chen Yi, continue to draw.

Even if there are many problems, such as air, food, etc., at least, we must first piece together a big direction and a viable big direction, and we cannot waste time and energy on the road to success when time is so tight.

This is his fifth draw today.

There is no purple, a pile of blue and white.

The sixth time, the same is true.

The seventh time, a purple-grade item appeared, which was a huge engine technology that was not as good as Dingliu's anti-gravity power furnace, but was also used on aerial fortresses like Dingliu.

Let Chen Yi's eyes lit up slightly.

Can it be used to create floating cities?

Unfortunately, the price is too high.

If you have 800,000 points, please let Dingxiang calculate it. In the end, more than 8 million points are needed, that is, ten such power furnaces can save one million people.

If you have not found a technology or item that can hope to solve the disappearance of land ten times, Chen Yi will be ready to stop for the time being.

Wait and get more points before starting to draw.
Chapter completed!
