If the subway is set to a vacuum state, the speed will reach a very terrifying state.

In a vacuum state, it must be sealed. With rubber as a subway door, it is difficult for air to enter the tunnel.

Since crystals are synthesized, both hardness and toughness are good. I suddenly had an idea to use synthetic crystals to make carriages and rails?

Try it, crystals can indeed make rails and subway cars.

The tilted cave was dug out and was dug up to a thousand meters below. A lot of groundwater appeared below, making the project unable to proceed.

Ning Caichen controlled the mental power and true energy of more than a dozen rhinos, isolated the water, and then burned the rocks to form a tunnel shell, and engraved the magic circle on the shell.

It is just a hundred meters of tunnel shell, and the brain is dizzy and brain power is overspent.

Ning Caichen had no choice but to rest and sit down cross-legged.

After adjusting for a while, your brain power will quickly recover and become energetic, and you will start to consolidate the outer wall of the tunnel again.

Ning Caichen constantly used his brain power to control the mental power and internal strength of the Rhino King. After his brain power was consumed, he replenished many times, but he actually found that he had improved slightly. He was overjoyed and built the tunnel even more crazily.

When the tunnel is opened, it leads directly to Aihua Town, and the mental space reaches the critical point and reaches a bottleneck.

Ning Caichen thought that using brain space to control other people's internal strength can improve his brain power, so it is better to build a modern city.

The masters of the Rhino Clan and the Tianxian Clan were all concentrated. Ning Caichen used rocks to synthesize crystals and began to build Daxia.

When the Rhino City City was built, the brain power and space were shocked!

Ning Caichen was ecstatic and had already touched the bottleneck. He could break through with more effort.

Ning Caichen is looking forward to a breakthrough. After all, once it breaks through, the mental space can bloom within one meter of the body, and the mental power can also directly extract the mental power of the slaves. They can guide the brain to stand in the space without them blooming.

Ning Caichen simply destroyed and rebuilt the buildings in Aihua Town.

The small courtyard and mansion of the past were destroyed, and then the shining tall buildings of Daxia were built.

The subway has been opened, and the electricity from Rhino City has also been guided to Aihua Town.

All electrical appliances are used in Aihua Town.

The subway is intelligent, so Ning Caichen had to make a computer.

Since taking the subway requires a fare, the world is about exchanging materials, so I don’t know how to charge the fare.

Ning Caichen simply learns about the earth's mobile payment, shaving verification payment, blood verification payment, and breath verification payment.

We have created digital currency, and we just need to exchange materials for currency.

Ning Caichen did not expect that such high-tech payment would appear, and his sins would decrease rapidly, and he was overjoyed.

Wireless base stations were set up in the two cities, because the plane level here is very high, even immortals cannot use Qianli to transmit voice, and many spells cannot be used here.

Meng Xi and the four young masters can use magic here, after all, their cultivation level is too high.

Even the immortals in this world can be instantly slight.

This is a cultivation civilization, so there is no technological civilization. Ning Caichen created a technological civilization, so it is also a supreme merit and will naturally reduce sins.

Electronic data currency appeared, and many mercenaries were afraid to use it at first, but later they saw that it was so convenient, so they exchanged materials for currency.

Once you have electronic deposits, you buy a mobile phone, you will see your own wallet, and you will see many products on the mobile phone online.
