The reason why the exploration team came back this time is obviously very simple.

That's when winter is approaching.

According to their situation, without sufficient resources.

Obviously it is impossible to survive an entire winter in a bitter cold place.

Therefore, we must withdraw before winter.

To avoid being buried in the cold winter.

But even so, many people still died during the exploration team's trip into the bitter cold place.

Regarding the pension issue for the family members of the deceased.

Luo Ji has already ordered people to make arrangements.

The next task of the exploration team is to sum up experience.

Then, after the spring of next year, we will continue to carry out exploration missions deep into the bitter cold areas.

The area of ​​the Bitter Cold Lands is vast.

From the system map, Luo Ji could clearly feel that there was still a large amount of fog surrounding the area.

These horizons must be slowly opened up.

At the same time, locations with resources must be marked one after another.

This is all to prepare for his future territorial expansion.

At the same time, Luo Ji also went offline to check the ores brought back by the exploration teams.

If he was not mistaken, what the exploration team brought back should be 'tungsten ore', 'manganese ore' and 'titanium ore'.

Luo Ji clearly realized that the frozen soil was extremely rich in mineral resources.

However, the meal must be eaten bite by bite, and the road must be walked step by step.

He started to expand the size of Baihe City this year. In fact, he was already preparing to expand his territory to the bitter cold land.

According to his development plan.

The next step should be to occupy the northern mountain forests that connect the Central Plains region and the bitter cold land.

Build a mountain city there.

Then, using that mountain city as a bridge, we continued to expand towards the bitter cold land.

This is one of Luo Ji's expansion plans in the next few years.

There is no doubt that this is another big project.

The difficulty of building a city in mountainous and forested areas is much more difficult than that in plain areas.

Even before that, he had to build a sufficiently spacious mountain road in the northern mountains and forests.

Otherwise, the transportation of building materials for city construction would be a huge problem.

Time continues to flow, and as the days pass, the temperature of civilizations in all worlds becomes colder.

The season is gradually entering winter.

Luo Ji had also put on a warm cashmere sweater for himself.

Recently, on the other side of the grassland, Xueyu from Baize and Gege from Burigude have frequently sent letters via flying eagles, sending a lot of news.

One of them is, of course, that the extermination of the horse thieves went very smoothly.

So far, they have destroyed three dens of horse thieves.

It made all the horse thieves on the outskirts of the grassland feel more at ease.

Some groups of horse thieves even simply fled back to the depths of the grassland.

Another piece of news was sent back by spies who went deep into the grassland.

Deep in the grassland, there is no movement among the large tribes on the grassland.

Judging by the time, if those large tribes want to migrate to the outer areas to spend the winter.

Action should be taken as early as the beginning of the month, or even last month.

There has been no movement so far, which means that they plan to spend this winter quietly deep in the grassland.

On the contrary, it is those small tribes.

Probably because the large tribes have taken over all the pasture resources.

This makes it difficult for them to continue to survive in the depths of the grassland.

One by one they all started to run outside.

During this time, many small tribes have migrated outside.

Faced with this situation, Bai Ze and Burigude were asking Luo Ji for instructions.

Should we eradicate those few small tribes before the temperature drops further, or should we integrate them?

To this, Luo Ji's answer was to keep those small tribes at a safe distance from them.

In other words, everyone does not offend the river.

Luo Ji didn't pay attention to the threats posed by a few small tribes.

At this point in time, if he chooses to incorporate those small tribes, it will undoubtedly increase the food consumption and burden of the grassland city.

But if it is removed, it will easily cause extraneous branches.

This caused a strong backlash from other small tribes.

To put it simply, this matter is very troublesome!

Winter is coming soon, and this cold season will not be easy for ancient people.

If those small tribes know each other better, keep a good distance from them.

Wouldn't it be better for everyone to spend this winter peacefully?

Of course, if they don't recognize it, then take some trouble to get rid of it.

The task of sending the message was naturally given to Lve Ying.

Probably because of the bitter experience last year.

This winter, Lv Ying obviously has no plans to go out in the wild.

He stopped quietly on the scaffolding and dozed off.

Occasionally send letters to Luo Ji.

In this era when long-distance communication is difficult, flying eagle letters should be the most efficient means of transmitting information.

Of course, not everyone can afford to raise an eagle.

So Luo Ji had already started asking people to tame homing pigeons.

For this reason, I went offline to check the information for a long time.

However, so far, the domestication effect is not very good.

In the recent reports of pigeon training that have been sent, pigeons often get lost and letters fail to be delivered to the designated location.

This won't work.

Luo Ji wanted to use them to convey military intelligence and battle reports.

Such unreliable results obviously cannot meet his requirements.

There is no other way, just continue training. What else can I do?

In comparison, the new discoveries on the other side went very smoothly...

Luo Ji tore off the dirty-looking, yellow leather cord in his hand, and a trace of satisfaction flashed across Luo Ji's face.

This thing is rubber!

Of course, more accurately, it is natural rubber.

It was found in the large forest to the south where the orcs used to live.

Resin is one of the important resources of their civilization.

The most direct function is that it can be used to make hard leather, and then made into leather armor.

Therefore, after discovering a forest, the collection team will naturally rush to collect and confirm resources.

As a result, after they cut the bark of some trees, they found that those trees exuded a milky white glue.

It is the so-called natural latex.

After processing the natural latex to a certain extent, there was the small piece of natural rubber in Luo Ji's hand.

The role of rubber is undoubtedly extensive.

Take the military aspect alone, three-bow bed crossbows, catapults, hand crossbows, and other ordnance and equipment are all used for this.

In other words, these weapons and equipment of his civilization can be further improved and strengthened.

As for civilian use, there are even more places where it can be used.

However, priority will be given to military-related departments.

After all, the output of this natural thing is relatively limited.

It is not yet available in large quantities for civilian use.

As for those trees that can produce natural latex, Luo Ji simply named them rubber trees.

People have already begun to carry out artificial breeding.

Within a few years, he should be able to obtain a more sufficient and more stable supply of resources.
Chapter completed!
