"I estimated it based on the number and size of the caves, and the amount of demons that the smallest caves can hold. They are clearly a force with sufficient combat effectiveness to wage a war that can destabilize the power of a country. We have alarmed their guards and cannot go back. "Mulan Road.

"Well, okay then. We're almost resting now, so let's hurry back to the Great Wall. Xiao Zi said.

After a short break, the group continued to fly away south. After three days of flying and trekking, we finally returned to the Great Wall.

Baili Xuance happily went to the barracks to look for Kai, who was wiping his sword.

"Brother Kai, they're back, they're back." Baili Xuance said.

Kai raised his head suspiciously, looked at Baili Xuance inexplicably, and said with a smile: "Who is here?" Turns you on like this. ”

"My sister Mulan, they're back, and they've just entered the city." Baili Xuance said.

Kai's eyes suddenly became bright, he stood up, looked in the direction outside the camp gate, and said, "Xuan Ce, let's go, go and meet them." ”

"You don't want to see them, you want to see my sister Mulan." Baili Xuance laughed.

"Stinky boy, are you looking for a fight?" Kai touched Baili Xuance's head.

"Hehe, Brother Kai, I'll show you the way." Baili Xuance ran out of the camp gate as soon as he slipped through the smoke.

Since Gao Changgong stepped down as the Great Wall guard, Su Lie has acted as his agent.

"Mulan, you're finally back. This expedition to the north is hard for you. Su Lie said.

Hua Mulan just wanted to open her mouth to call Su Lie "Brother Su", but because of his identity, she immediately changed her title. Hua Mulan always felt that there was some kind of faint estrangement between her and Su Lie that was difficult to describe in words. "Sir, I'm a derelict captain, I took 10 people to set off at first, and now I've only brought back 4." Mulan lowered her head with a guilty look on her face.

"Mulan, I have a very clear understanding of the whole exploration process. Your captain is very competent, and your exploration team has also probed the general situation of the demons very specifically. This provides valuable parameters for our future strategic defense. Su Lie said.

When Mulan finished reporting her work, she went to the barracks cafeteria and happened to meet Kai. The two of them looked at each other, saying a thousand words but not knowing how to speak.

"Captain, I heard that you went to the Far North, and you just came back today." Kai was the first to break the silence.

"Well, I didn't expect you to come back, I thought..."Mulan muttered, her cheeks suddenly turning crimson.

"Well, I've only been back for a few days. I have recalled all the things of the past, and the great revenge has been avenged. The brothers of the Great Wall saved me back then, how could I just leave, I have long regarded this place as my home, not to mention... What's more, the captain also took good care of me. At the end, Kai looked at Mulan's eyes with affection.

The crimson on Mulan's face became even more intense, and she hurriedly turned her face away, flashing Kai's affectionate gaze.

"I'm going to get something to eat first, we haven't had a hot meal in a long time." Mulan hurriedly found a topic to defuse the awkward atmosphere.

"Oh, I just didn't eat either, let's go together." Kai smiled slightly.

"Okay, let's go." Mulan said shyly.

"Captain, you might as well tell me, what did you gain from going to the Far North this time?" Kai asked.

"This time, we went deep into the Northland and explored the distribution location, number, and weapons and equipment of the demons. They are mainly concentrated in the northernmost cave dwelling mountains, numbering 300,000, and they also have a special weapon foundry. "Mulan Road.

"In other words, if they want to start a national war, they all have the strength." Kai was surprised.

"That's right, it is estimated that in the absence of food sources, they can also use their green skin to photosynthesize to replenish their physical energy." Mulan Road.

"It's weird, aren't they moving plants, and the natives of Proxima Centauri are really extraordinary. In terms of sustained combat, we are not at all on the same level as others. They can replenish their energy while fighting, and we have to eat food. Kai Tut.

"Well, but they also have a weakness because of this, which is that they are slightly less capable of fighting at night than during the day. Therefore, in the future, we would better fight them at night. "Mulan Road.

"Well, that's really a coping strategy. Captain, but there is one thing I don't understand, since the demons have such a strong military strength, why do they always launch small-scale incursions and attacks instead of large-scale corps operations? Could it be that they are waiting for something? Suddenly, there were many suspicions.

"If I'm not mistaken, it's because of the arrival of the snow season in the north, the lack of sunlight and food, which caused them to retreat into caves and not be able to carry out large-scale military operations." Mulan Road.

"And how long will their snow season last?" Kaidao.

"Listening to Brother Sun Bin, it will probably last for half a year." Mulan Road.

"Half a year, that is to say, we only have half a year to prepare." Kai muttered quietly.

"Prepare what?" Mulan Road.

"After I returned to the Great Wall from the Land of Warriors, I heard a lot about the actions of the demons. Not only did they harass the Great Wall, pursued the Western Regions, coveted the Land of Origin, and colluded with those in power in Chang'an, but in this way, their perspective was to look at the entire Eastern Continent, even the Land of Warriors. "Kaidao.

"You mean to say that the demons want to dominate the entire King Continent." Mulan was shocked.

"That's right, their ambition is to rule the entire King Continent. If the armies of the entire King Continent were not united, the existing Tang army would not be enough to confront them, because their ambitions and growing strength should indeed not be underestimated. "Kaidao.

Kai saw that Mulan was inexplicably in a deep thought, didn't know what to do, and said in a gentle tone, "Mulan, what's wrong with you?"

As soon as the two words "Mulan" blurted out, Kai felt that he was reckless. Pretending to have an uncomfortable throat, he coughed twice.

When Mulan heard this, Kai changed her salutation, and a burst of crimson swept across her cheeks.

"Oh, I'm fine, I just didn't expect that the people in power in Chang'an would collude with the demons, so what is the point of us guarding the Great Wall?" Mulan seemed to be quite distressed.

"If the people in power in Chang'an disregard the survival of the people and continue to collude with the demons, our Great Wall Guards will naturally stand up and fight the demons to the end, isn't the original intention of our Great Wall Guards to swear to defend the Great Wall and protect the people?" Kai said angrily.

"What do you mean—" Mulan didn't dare to continue.
