Li Yan and Tie Dan stood by the lake, Li Na stood next to them and whispered a spell, and after a while, a layer of aqua blue transparent shield appeared around them, and then a wave came out of the lake, just when Li Yan was stunned, the wave swept the three of them into the lake.

But Li Yan found that the three of them were now standing in a transparent ball of water blue, while the lake water had been holding their transparent ball like a fountain, constantly moving forward.

This is the second time Li Yan has seen the magic of magic, the first time, Li Na just used a simple lighting technique and a simple water polo technique, but even then, it also made Li Yan, who saw magic for the first time, feel very magical, and this time it was even more magical than the last time, they were actually treading waves, and they were also alone with two people, which was even better than the "water floating" and "crossing the river with a reed" in Chinese martial arts.

Compared to Li Yan, who is half of the outsiders, Tie Dan's performance is much more shocking, he has long known the magic of magic, not to mention that Li Na is still an eighth-level water system great magician, fighting in the water with such a magician is everyone's nightmare, because it is their home field.

Li Na also has a relaxed face, she is very confident in her ability, on the water, she believes that she is an invincible existence, so when she said that there may be water-based demonic beasts in the water, she has no worried expression at all, because she believes in herself, even if there is a water-based demonic beast, she can easily kill.

It took them more than three hours to use magic to move on the water, but when they returned, it only took about half an hour to see a cave in front of them, and fortunately, this cave was the cave behind the castle, which also proved that this lake could indeed be used as a waterway in the sky, allowing them to secretly transport people to the canyon.

When Li Na withdrew the magic and Li Yan finally got his feet on the ground, he still felt that he couldn't help but jump, this down-to-earth feeling was really good.

When walking on the water, although he looks very chic, Li Yan always has a feeling that he is about to fall, which makes him very uncomfortable.

When the three of them came out of the cave, they happened to see the slaves working outside, it was not yet noon, they had not rested, there were many places to be cleaned in the cave, and there were many slaves doing carpentry in the cave.

If this cave is to be turned into a place to raise blue-eyed rabbits, it needs a lot of fences, and these things are made of wood, after all, Li Yan and they don't have so many iron tools now.

This time, considering the situation here in the castle, Zhao Lin and the others also bought some wood, but it was not very much, Zhao Lin and most of the things they bought were some finished products, because Zhao Lin knew that among those slaves, even if some of them could do carpenter work, they would not be able to make too complicated things, because good artisan slaves are not the same price as these ordinary slaves.

The appearance of the three of them surprised the slaves, and they immediately saluted the three of them, and the three of them just nodded and went out of the cave.

Outside the cave, Zhao Xuan and Goudan were standing there, and when they saw the three of them coming out, the two of them were also taken aback, Zhao Xuan hurriedly greeted them and said, "Young master, grandma, why did you come out of the cave?" ”

Li Na smiled and said, "Walking all the way from the lake in the cave, you can reach a canyon, which is the most suitable place for us to cultivate, and the young master has just improved ten acres of land there, so we will come back." ”

Zhao Xuan's eyes lit up and said, "Really? That's great, I didn't expect things to go so smoothly, grandma, young master, you go back to the castle and rest, I'll just watch here. ”

Li Na turned her head to Li Yan and said, "Young Master, go back to the castle and rest, I have something to tell you." ”

Li Yan was stunned for a moment, not knowing what else Li Na had to do, but when he saw Li Na's solemn face, he didn't dare to slack off, and immediately nodded and said, "Okay, then let's go back to the castle first, Tiedan, you stay here to help Zhao Xuan and the dog." Tie Dan answered, and Li Yan and Li Na walked towards the castle.

After the two arrived in the living room of the castle, Li Yan looked at Li Na puzzled and said, "Grandma Li Na, what can't you say outside?" ”

Li Na nodded and said to Li Yan: "Young master, when I came back today, I explored the situation in the lake by the way, but I didn't find any powerful water system magic beasts, there are only two explanations for this situation, first, that water system magic beast is very powerful, and it is very good at hiding its whereabouts, so I can't find it, but this situation is almost impossible, I am an eighth-level water system magician, and I am confident that there is nothing in the water that can hide from my exploration, and the second situation is, There are no powerful magical beasts in the water at all, and there are no fish in the water, there is another reason. ”

Li Yan was stunned, but he immediately realized the seriousness of the problem, the mountain lake is one of the important plans for the development of his fiefdom in the future, if there is really no way to raise fish there, then he will lose an important source of funds, and there is such a large lake water that cannot be used, which is really too wasteful.

Li Yan said with a calm face: "Can you find out the specific reason?" ”

Li Na also said with a heavy face: "I heard a rumor, I don't know if it is related to the situation in the lake, I heard that because the Loess Plateau is too close to the Yunmeng Swamp, there are often some necromantic creatures and poisonous monsters composed of a coalition army to run to the Loess Plateau, they will kill all the living creatures here in the Loess Plateau, so the Loess Plateau has become a dead land, but because no one will come here on the Loess Plateau before, so this news has not been confirmed, If this news is true, then the reason why there are no fish in the lake may be because of this. ”

Li Yan's face changed, if it was really like what Li Na said, then the matter would be in big trouble, among them, except for Li Na, Zhao Xuan, Zhao Lin, Tie Dan, Dog Dan, these people have a little combat power, the rest of them are some slaves who have no combat power, if the necromantic creatures and poisonous demonic beasts in the Yunmeng Swamp really come to attack them, then they will die.

Li Yan lowered his head and kept rubbing his forehead with his hands, which was also a habitual action when he was thinking about things in his previous life.

Li Na looked at Li Yan's appearance, and was also very worried, if that situation really happened, then all their cultivation industry would have to stop, and it was very difficult to say whether they could live or not.

Li Yan couldn't think of any good way now, so he had to say: "If this matter is true, then we will be in big trouble, Grandma Li Na, this matter is still waiting for Grandpa Zhao Lin to come back, we are discussing and deciding, I think so, from tomorrow onwards, don't go to clean the mine first, gather all the materials in our hands, build some simple weapons, and then train those slaves, and at the same time carry out some repairs to the castle, if that really happens, We can at least rely on the castle to resist for a while, if it really doesn't work, I can only take everyone into my space, let everyone take shelter in the space, and when those necromantic creatures and monsters retreat, we will come out. ”

Li Na frowned and thought about it, but she really couldn't think of any good way, so she had to nod and said: "It seems that it can only be like this now, we have been here on the Loess Plateau for so long, and we haven't seen any changes in Yunmeng Swamp, there should be no problem, I hope my worries are superfluous." ”

Li Yan shook his head and said: "Whether it is unnecessary to worry or not, this matter has to be done, prevention is better than prevention, now that the last of our Kalin family is here, if we all lose, then our Kalin family will have no hope of turning over." ”

Li Na nodded and said, "Okay, then I'll arrange it right away, but we didn't bring many weapons this time, and most of those materials were some living supplies, so they couldn't be made into weapons at all, so what should I do?" ”

Li Yan doesn't have any good idea now, if the level of his farm is enough, he can plant some trees to use as weapons, but his current level is too low, he can't plant trees at all, he can't let people take a corn stalk to fight those necromantic creatures.

Li Yan rubbed his forehead vigorously, his forehead had been rubbed red a lot, but he still didn't come up with any good way, suddenly, he noticed the stone ground, a bold idea appeared in his mind, he looked up and said to Li Na: "Grandma Li Na, I think so, tomorrow we will organize people to pick some stones and come back, we can make some stone weapons, although the lethality of these weapons is not large, but we are only to defend the city, we should be able to use it, you see?" ”

Li Na thought for a while, nodded and said: "Okay, now we don't have so many supplies in our hands, when we came out of the imperial capital, they didn't let us bring weapons at all, and now we can only do this, when Zhao Lin comes back, let him go and purchase a batch of weapons as soon as possible." ”

Li Yan nodded impatiently, he never thought that one day he would return to the life of the Stone Age, and they had to face it.

Li Yan can be considered to have figured it out now, it seems that those old men in the imperial capital really don't give them a way to live, otherwise they won't come to a place like the Loess Plateau without letting them bring weapons, he doesn't believe that those big men in the imperial capital haven't heard of the rumors here on the Loess Plateau.

Now they have to face not only the danger of starvation, but also the possibility of being killed by those necromantic creatures and poisonous monsters.
