Speaking of alloys, Shen Yi remembered 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 type of alloy, which is tough and light, with a relatively simple production process. Once forged, it is extremely difficult to damage. It is widely used in projects such as mecha shells and spacecraft shells. The defensiveness depends on the thickness.]

As he read the introduction, Shen Yi's eyes became brighter and brighter.

Put these two technologies together.

It reminded Shen Yi of a picture.

——The indestructible city.

Both of these technologies can be used for mass production and have low production costs. Even if they cannot prevent the impact and coverage of a tsunami, at least they should be able to block hurricanes and major earthquakes in the next few months.

Existing cities are simply unable to withstand an attack of that scale, and rebuilding cities or shelters that are strong enough to withstand it is an urgent task.

Otherwise, leaving people exposed to the bad weather will only lead to death.

"Dingxiang, take these two technologies and simulate and calculate the feasibility." Shen Yi exchanged the technology in the form of information storage and passed it to Dingxiang.

Then, let Clove simulate the calculation.

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

Even for lilac, it can only be estimated in large quantities.

Finally, a probability was obtained.

"The feasibility is between 46 and 85 percent." A simulation of Lilac appeared on the projection in the captain's room.

It was a city with high walls. The architectural style within the city was extremely monotonous. However, you could see that at the foot of the city, there was a huge foundation connected together!

As the model began to become transparent, the interior of the entire city was clearly displayed in front of Shen Yi, a skeleton constructed of dense alloys.

Extending from the foundation to each building.

This doesn't seem like a real city.

But it is an entire, indestructible industrial creation!

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

"There is a lack of data. In addition, I am not a top construction talent, so I have no idea about the efficiency of mobilization and infrastructure construction." Ding Xiang explained, "Besides, there is currently no accurate data on the scale of hurricanes and earthquakes."

"What is the level of these two technologies?" Shen Yi asked again.

"From the perspective of this era, it is at the 'science fiction' level." Ding Xiang directly showed Shen 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. Titanium alloy is also widely used. It can be used in large quantities on mecha shells and even spacecraft."

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

"It may not be possible to produce the highest quality, but ordinary or even inferior quality should be no problem." Ding Xiang replied, "Captain, my calculations have already taken this factor into account. Otherwise, the highest feasibility should be close to 100%."

Compared with those planets in the universe with more harsh environments.

This kind of change in the earth's environment can only be described as "mild".

"So." Shen Yi's expression became a little serious, and he asked the last question, "What about the possibility of building an underwater city?"

The entire continent will eventually be completely covered by sea water, and even after everything calms down, only a small part will be exposed.

That should no longer be the mainland.

Underwater city, if it is really feasible. However, Dingxiang did not give the answer that Shen Yi wanted.

"I'm afraid not, Captain." She directly gave the relevant picture in the technical data. "The 'lightness' feature of this building material comes from its unique 'empty window' structure, which allows it to stand on certain planets with high gravity. However, although long-term immersion in water will not cause damage, it will allow water molecules to gradually penetrate into the interior of the building."

In other words, everything is good except that it can't block water.

It won't be completely sealed.

"Like this." Shen Yi narrowed his eyes.

It is light, easy to produce, and has strong impact resistance, which almost meets the survival needs of people in this world, but it is not waterproof.

"According to Ding Xiang's guess, this kind of city should also have other supporting facilities to establish a colony on an alien planet." Ding Xiang said, "For example, protective shields throughout the city to isolate toxic gases and establish a micro-ecosphere."

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

This barely qualifies as an alien immigrant city.

But... I just didn't get such technology.

No, technology is useless. This kind of technology cannot be produced with the industrial level of this world. We need equipment specifically used to manufacture large protective shields.

"I'll try a few more times and see." Shen Yi looked at his remaining points.

You have to use it sparingly. A transport plane like the one just now requires 200,000 points to purchase one. And once the traffic roads are completely destroyed, it will definitely not be solved with just a few dozen planes.

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

If humans could really survive in an ocean.

Then this technology will probably play a huge role.

But, we have to live till then.

Shen Yi, continue the lottery.

Even though there are still many problems, such as air, food, etc., at the very least, we must first piece together a general direction, a practical and feasible general direction. We cannot let everyone in the world waste time and energy on a road that will not succeed when time is so tight.

This was his fifth draw of the day.

No purple, just a bunch of blue and white.

The sixth time, the same thing happened.

The seventh time, a purple-level object appeared. It was a huge spiral engine. It was not as powerful as Lilac's anti-gravity power reactor, but it was also used in air fortresses like Lilac.

Shen Yi's eyes lit up slightly.

Can it be used to build floating cities? Unfortunately, the price is too high.

One engine costs 800,000 points. Ding Xiang calculated that she would need more than 8 million points, which means she would need ten such engines to save one million people.

If he fails to find any technology or item that can solve the problem of land disappearance after ten attempts, Shen Yi will stop for the time being.

Wait to get more points and then start drawing again.
