Some time passed after that.

The invention of the hot air balloon caused violent repercussions throughout civilizations across the world.

Even now, many people can be heard talking about this novel gadget in restaurants and tea shops on the streets.

If we say that Luo Ji's previous development can only be called a reform.

So the emergence of hot air balloons is absolutely subversive for people of this era.

Humans, orcs, goblins, elves.

None of them can fly.

After all, they don't have wings like birds.

However, the emergence of hot air balloons made all people realize at this moment that they could fly into the sky without wings!

People of this era have officially taken their first step towards the sky at this moment.

From then on, the sky no longer became unattainable.

It has also become a part of the world waiting for them to explore.

The emergence of hot air balloons is of epochal significance.

And his use is of course not limited to collecting resources from ancient elven trees.

In addition, the Meteorological Bureau can also use hot air balloons to conduct high-altitude weather forecasts.

At the same time, in terms of military applications, the value of high-altitude reconnaissance is also huge.

As for civilian use, Luo Ji has no plans to put hot-air balloons into civilian use for the time being.

Although his people are extremely curious about this hot air balloon.

But he had no intention of changing his mind.

The reason is simple, because in this era, the sky is difficult to manage.

To give a simple example, what if someone with ulterior motives flies into the sky in a hot air balloon and throws kerosene barrels at the city below?

This is very dangerous!

It can be said to be a huge hidden danger.

Therefore, he does not intend to put hot air balloons into civilian use until he has sufficient control over the sky.

But even so, the enthusiasm of the people is still unstoppable.

Needless to say about the elves in the elven province.

Some people from outside the province couldn't hold back their curiosity about hot air balloons and traveled all the way to Kamikaze City to pay homage to this first flying vehicle in history.

This situation forced Luo Ji to order an isolation belt to be built around the ancient elf tree.

At the same time, additional patrols were deployed to maintain order around the area.

To prevent some onlookers from breaking in.

Then something dangerous happens.

As for the resource collection work of the ancient elven trees.

Luo Ji formed a special collection team.

The collection team was equipped with five hot air balloons as vehicles.

At the same time, four elf naturalists were added to the team.

They are nearly nine hundred years old.

I have a wealth of experience in nature research.

Specially responsible for taking care of the ancient elf trees.

How many leaves and branches can be picked at any given time without affecting the growth of the ancient elven tree are all left to the research and judgment of four elven naturalists.

To put it bluntly, Luo Ji found four nannies for the ancient elf tree.

After all, this ancient elf tree is a treasure and cannot be left to die inexplicably.

This is entirely based on profit and value considerations.

However, it is also in line with the elves' concept of maintaining natural balance.

As a result, his decision received strong support from almost the entire elven clan.

This allowed him to win over a wave of people's hearts by accident.

At the same time, the impact of the hot air balloon on the elves some time ago was taken advantage of.

Luo Ji began to deliberately arrange for goblin merchants to enter the elven provinces to open stores.

To put it bluntly, it is to increase the exchanges between the elves and goblins.

Human-powered bicycles and tricycles, as well as huge cranes and handling equipment.

The various technological products of goblin technology have brought many novel experiences to the people of the elven provinces.

Although the Elf King Zhang William and the Goblin King Gawain still dislike each other very much.

But the relationship between the people of both sides has been greatly eased.

The intimacy level has changed from zero to one.

This could be regarded as allowing Luo Ji to see some good signs.

If we try to improve the relationship in the future, we might be able to raise it to a friendly level.

Of course, this kind of thing cannot be done in a hurry and must be done slowly.

Being too impatient will only be counterproductive.

As the days went on, the cicadas outside the window kept barking, which was really noisy.

It’s already the hottest time of the year!

However, Luo Ji, who was leaning in the palace of Kamikaze City at this time, was not particularly miserable.

Probably because an entire elven province is located in the forest.

After opening the window, the wind in the forest was very strong.

Invisibly, it helped him dissipate some of the heat.

In addition, there are leafy ancient elf trees overhead to help block the sun.

During the recent period, Luo Ji had been relatively comfortable.

Take a gulp of the sweet lake water in the cup.

Luo Ji smacked his lips. Not to mention, the taste was indeed better than ordinary fresh water.

This is not ordinary water, but water taken from Xingchen Lake.

Xingchen Lake is only so big, and its freshwater resources are relatively limited.

It is certainly not enough to provide it to all people.

It's such a three-star natural wonder, we can't let them drink it dry, right?

Not to mention that the bottom of Star Lake also produces the important resource of ‘star sand’.

In this way, it is natural to protect it.

At present, the water of Xingchen Lake is only provided to Luo Ji, His Majesty the Emperor, and a few important ministers in the civilization of all realms.

At the same time, no one is allowed to steal water, and illegally selling water from Xingchen Lake is a serious crime.

In fact, William Zhang has done this before.

So for the elves, nothing has changed.

Let’s get back to the point.

After drinking all the water in the cup, Luo Ji had already made a decision in his mind.

That means that every summer from now on, we can go directly to the palace of Kamikaze Castle to escape the heat. The climate here is relatively comfortable.

However, the work that needs to be done still needs to be done.

Luo Ji did not forget that his own civilization was still in the Little Ice Age.

What's the scariest thing about summer?

Drought, locust plague, plague!

Prolonged drought will bring locusts!

If the drought has been going on for a long time, locust plagues will inevitably follow.

However, for these two natural disasters.

Luo Ji had already taken preventive measures before.
