However, having said that, Liu Ergou himself has no clue about how to live the most gorgeous appearance in everyone's minds.

In order to save the people of Beiyuan City, Lord Zhao decided to stand up and become an idol...... It shouldn't be popular now, right?

walked aimlessly for a long time, and when Liu Ergou reacted, he was already standing on the wall of the north gate.

In addition to the warmth and comfort of Kitahara, the late autumn season is equivalent to the honor guard of death for most places in Kitahara, followed by the winter day when the wasteland is washed with cold winds and frost and snow.

Standing on the city wall, Liu Ergou really felt the biting chill of the evening breeze in the wasteland, and couldn't help but pull his collar.

Fortunately, thanks to the addition of the second group of freedmen and a large number of goblin workers, the production capacity of both cotton and linen raw materials and finished products has been greatly improved.

The current Kitahara City can already ensure the food and clothing of all citizens (including goblins) in an all-round way, and the food and firewood for winter have also been fully stocked.

On the side of the R&D Bureau, Dami has taken the research team and began to demonstrate the feasibility of the "urban central heating scheme" proposed by Liu Ergou.

However, due to the high terrain on the city walls, the soldiers guarding it still had to face the cold wind of the night, and had to light large piles of bonfires to keep warm.

Liu Ergou came to a bonfire at this moment and exchanged pleasantries with a few soldiers who were warming up around the bonfire.

And in a pot on the campfire, some kind of fragrant food is being cooked at the moment.

Dried animal meat and other ingredients are processed into small pieces, mixed with powdered white leaf melon, and then added with a few compound spices, encapsulated in a cloth bag, and this portable ration developed by Amber is formed.

When eating, as long as you add some water and cook for three to five minutes, it becomes a pot of meat porridge that is both delicious and nutritious.

And when the conditions are insufficient, you can also make do with water and eat it, but it will be more sticky to your throat.

Liu Ergou also served a bowl of porridge and sat next to the bonfire to eat and chat with the soldiers.

The vast night sky is like an endless curtain, covering every corner of this cold land.

The lonely Beiyuan Castle is like a small island floating in this boundless dark sea, silently enduring the baptism of the cold wind that lasts all night like waves.

And this small bonfire on the city wall is like a lighthouse piercing the night sky on an isolated island, bringing comfort to the night vigil warriors at the same time.

......

On a cliff outside the island, a strangely shaped boulder suddenly shook to reveal a pair of scarlet eyes.

The eyes turned slowly, then turned their gaze in a certain direction.

In that direction, there is a makeshift camp.

The eyes were fixed on the camp as if they would never get tired.

It took about half an hour for his eyes to stop looking and turn his gaze back to him.

The boulder continued to move for a few moments, revealing a four-clawed, winged, two-horned figure.

None other than Winston.

Winston, who was de-petrified, stretched his body and pulled out a small cage covered with cloth from his bosom.

In the cage, a blue-winged bat nested in a heavy and soft cotton cushion, sleeping soundly at the moment.

Winston held out a finger and poked the blue-winged bat with some kindness.

The blue-winged bat suddenly woke up and chirped at Winston with some dissatisfaction.

"Okay, okay, my fault, I shouldn't have disturbed your sleep," Winston's fingers scratched the ears of the blue-winged bat, who immediately snorted in comfort.

"I'll go to bed after finishing my work in a while, and I'll bring you jerky!" Winston said, plucking a piece of jerky from the small box next to the cage and shaking it at the blue-winged bat.

As soon as he saw the jerky, the little thing immediately stopped sleepy, not only staring at the jerky in Winston's hand with longing, but even the corners of his mouth dripped saliva!

"No! I'll give it to you after the work is done! As soon as Winston took it away, he took the jerky back, pulled out a small roulette wheel, and placed it in front of the blue-winged bat.

The blue-winged bat shook it a few times reluctantly, stretched out a claw, and put it on the wheel.

"Well, that's good," Winston said, pulling out another notebook and flipping through it for a moment by the faint light of a small piece of magic crystal.

Winston then spun a row of symbols on the roulette wheel according to a certain rule.

And with the rotation of the roulette wheel, this blue-winged bat also continued to exude bursts of fluctuations of different attributes, quickly passing in a certain direction.

This roulette wheel is the latest achievement of the "Blue Wing Bat Communication Project".

Taking advantage of the elemental resonance of the blue-winged bat, Dami, Liu Ergou and Ellanster teamed up to design such a roulette wheel that could emit magic of specific attributes.

There are five slots in the wheel, except for one "send" slot, the remaining four correspond to the four basic attributes of earth, fire, water, and wind.

As long as the slot of the corresponding attribute is transferred to the "send" slot, the magic circle in the wheel will be activated, and then a weak flow of mana corresponding attribute will be generated.

The blue-winged bat, which has been trained, will sense this flow of magic and send out corresponding elemental resonances in a specific direction.

Similarly, the blue-winged bat at the receiving end will input the corresponding mana flow to the roulette wheel according to the resonance of the received element, and then the roulette wheel will be restored to the original rotation order. The small notebook that Winston was holding was the "codebook" used to record the messages corresponding to the combination of elements and specific text messages.

However, for obvious reasons, this means cannot be used to convey too complex information.

And because of the small emotions that often appear in the "tool" itself, this means is also not suitable for use in scenarios such as the battlefield, where there are large stimuli and factors; "Tools" are equally unusable when they are emotionally unstable.

In fact, with the exception of Winston's group of secret sentinels, normal patrols rely on horns during the day and fireworks at night.

After sending the message, Winston handed the jerky to the salivating blue-winged bat, and reached out and tapped a few stones beside him.

After a slight shaking, the stones turned into smaller gargoyles.

Following Winston, the gargoyles rose silently into the air, and disappeared into the darkness of the night in an instant.

In less than a minute, the listening tower set up at the forward base received a summons from Winston. An Olo warrior on duty immediately spread his wings and took off, flying at full speed towards Kitahara City.

The reason why the listening post is set up in the forward base is to avoid the interference of the magic energy of Kitahara City, and secondly, it is also to facilitate the breeding and management of blue-winged bats.

In less than twenty minutes, Bufax, who received the news, found Liu Ergou on the city tower and informed him of the content of the summons.

"Boss! A camped unit was found about 450 kilometers southwest of the Huangtie Cliff, and it was preliminarily judged that it should be a mercenary group or a slave hunting group! ”
