At This Moment, the World Has Entered the Ice Age

"My dear, this freezing rain is too terrible, and I can feel the cold air just falling on the ground through the protective clothing."

"It's true that I haven't encountered anything so cold since the Ice Age, and I can feel this biting cold even in winter clothes."

"It seems that some fences will need to be erected around this greenhouse in the future, otherwise the cold air generated by the freezing rain will enter the underground "Zero 20" base, and it will also cause damage to the built mechanical parts."

Soon the frozen fish had passed. I saw a layer of bright frost formed on the antifreeze greenhouse. The frost attached to the antifreeze liquid, which also decorated the antifreeze greenhouse with a beautiful landscape.

Now that the environmental problem of freezing rain has been solved, the next step is to start building underground bases.

A large number of workers came from all directions, armed with various digging weapons, and began digging deep into the ground under the antifreeze greenhouse.

It took a long time to dug out a huge pit with a depth of one hundred meters. The construction of the underground base is very simple. You only need to build it according to the previous design drawings for making giant soldiers.

Soon, a brand new underground base was introduced. The outer layer of this underground base uses a graphene and alloy structure.(Read more @ mtlarchive.com)

After all, the main threat to this underground base comes from the freezing rain above, and the freezing rain has been blocked by their uppermost frost-proof greenhouse.

Therefore, the materials used in this underground base are much rudimentary compared to the materials used to build the Giant God Soldier Manufacturing Center.

With a very safe engineering and construction base, they began to build huge hot air balloons, which are the most important part of the sky city that can float in the sky.

Without this huge hot air balloon, the city in the sky, even if it is exhausted with all the current technology, it would be difficult to suspend it in the sky.

Soon, everyone in the underground base made a huge hot air balloon using synthetic rubber materials, and then used a special coating to reinforce the huge hot air balloon.

In this way, this meat ball has become an indestructible rubber ball, even if it is pierced with a knife, a spear, a sword, and a halberd, it cannot cause any harm to it.

"As a result, this huge hot air balloon has been manufactured 0..."

The engineers from the National Engineering Department couldn't help but look at the huge hot air balloon in front of them, and saw that he can stack up to one floor in a dry state.

I really don't know what a terrifying scene such a huge hot air balloon would be if it were really opened.

"The hot air required for such a big hot air balloon must also be very huge. So far, the machine that can produce such a huge amount of heat is only the Vulcan Energy Heart. However, with such a huge volume, the Vulcan Energy Heart can only be supported by a few more. Live."

At this moment, the National Engineering Department received a good news, Binhai Energy Center developed an upgraded version of Vulcan Energy Heart called Vulcan Energy Supernova Core!

As the name suggests, the core of this Vulcan energy supernova is a fusion of ten Vulcan energy hearts. Its energy system is not as simple as one plus one.

"Next only need to use a Vulcan energy supernova and several other Vulcan energy hearts as control, then it can generate enough heat to make it lift off.".
