In the blink of an eye, it has been two months since Xiao Tianxing returned to the Hungarian Fortress from Liyang.

During this time, the Hungarian fortress was never attacked on a large scale except for a tentative attack by the Xixia Principality.

Taking advantage of the period when the first pair was stable, the reconstruction work of the fortress was also carried out greatly.

Although Ran Yun has always wanted to build some fortifications outside the fortress, in anticipation of controlling the battlefield in the outer area.

However, after careful consideration, he gave up this plan for the time being.

It is true that according to the drawings of his own design, Ran Yun believed that he could control the battle forty zhang away from the fortress.

But after several engagements, he also figured out the dangers of leaving his army outside the fortress.

Even if all the dangers can be eliminated, even if the total amount of the entire project is lightly, it will never be completed within a year.

After carefully summarizing and sorting out all the invitations, Ran Yun felt that Xiao Tianxing's idea of building a town in the rear would be more feasible.

At least the entire Hungarian fortress served as a barrier, and the construction of the town was much smoother.

After figuring out everything, Ran Yun still didn't let go.

This time, his eyes were on the construction of a trap outside the fortress.

In fact, Ran Yun also drew this matter on the design drawings at first, so it was relatively easy to implement this time.

However, this time his plan made Xiao Tianxing, who had never complained bitterly, start to snort hard.

"Brother Ran Yun, what do you want to do? We have been dragged by you to dig a ditch, but it has been five days! You can't keep it a secret!"

Hearing Xiao Tianxing's complaints, the girls in the crowd also agreed.

"Yes, yes, it's all right for us to do the labor, but you should always tell us what you're going to do!"

Throwing a shovel of soil in the direction of the fortress, Ran Yun reached out to wipe the sweat from his forehead, and looked at everyone who was complaining.

"Okay, I'll tell you my purpose! I'm going to dig a moat. ”

"What? Brother Ran Yun, you don't have a fever, do you! Dig a moat!? Dig this moat, where are you going to get the water?"

"Hehe!" Looking at Xiao Tianxing's expression, Ran Yun also pretended to smile mysteriously.

"Don't worry about the water! Uncle Yi Shui will help us solve it. ”

"Second uncle? Yes, I haven't seen him for more than ten days, did you let him go looking for a water source?"

"That's right. And Tianxing, look at this moat we dug, how far away is it from the Hungarian fortress?"

"How far is it?" Looking back at the walls of the Hun Fortress behind him, Xiao Tianxing roughly calculated.

"It's about four feet away! At a distance of four feet, the wall is one zhang away, and if someone digs a moat here and fills it with it...... Brother Ran Yun, do you want to use this method to guard against attacks from underground?"

"That's right, I'm trying to use this method to prevent attacks from underground. First of all, within three zhang of the Hunga Fortress, because of the existence of special stone walls and nodules, those bugs cannot attack from the underground. ”

"In other words, if they want to attack from underground, they can only come out three feet away, which is the land under our feet now. ”

"Now that we're digging a moat here and filling it with water, what do you think will happen to these bugs when they attack from here?"

Ran Yun's words couldn't be more obvious, and everyone's eyes lit up instantly at this time.

"If the bugs are going to come up, they have to burrow. As soon as it burrows, whoever is inside the moat will pour into the cave, and their sneak attack will be discovered. ”

"That's right, although the water may not be able to drown the insects, but as long as they enter the water, and Uncle Yihan or Sister Ge Xin are here, what do you think will happen to them?"

Hearing this, everyone also understood what Ran Yun meant.

Yi Han cultivates Ice Source Qi, and if he attacks in a place with a lot of water, his power will definitely increase exponentially.

As for Ge Xin, it's even simpler, just thinking about the result of thunder and lightning entering the water, there is an instant feeling that makes people feel numb.

Just when everyone's minds were making up the wonderful picture, Ran Yun added again.

"Besides, we have Uncle Yi Han and Sister Ge Xin here, but there are also Sister Yao Xue and Sister Fei'er, the two of them are also ice and thunder!"

"If there is enough water, I believe that Uncle Yi Shui, as a cultivator of water attribute source qi, can also exert great combat power. ”

"You're right, kid, as long as there is water, my strength will indeed be much stronger. ”

The figure of Yi Shui appeared between the voices, and it also slowly fell from the air into the moat that Xiao Tianxing was digging.

Seeing that Yi Shui, who had not been seen for many days, came back, Xiao Tianxing threw away the shovel and ran over.

"Second uncle, where have you been these days? I miss you a little. ”

"Hehe! The second uncle misses you too. Well, judging by your spirits, there shouldn't have been anything major going on inside the fortress. By the way, how is my sister-in-law's health?"

"Ahh In addition to becoming fond of spicy food, my belly has become a little bigger. ”

"Oh, do you like spicy food, it looks like you want more than one sister!"

"Really, second uncle, how do you know that your mother is a sister in her belly?"

"Hehe! You'll know when the time comes. Alright, let's get down to business now!"

"What Ran Yun asked for, I got it for you. Saying that, Yi Shui took out a drawing on his body and handed it to Ran Yun in front of him.

"I'm sorry for you, Uncle Yi Shui. ”

"It doesn't matter what trouble is not trouble. By the way, what are you doing here?"

"Second uncle, we are digging a moat, this is a good idea for Brother Ran Yun to defend against insects!"

"Moat, what are you paying attention to?"

"Ahh

After listening to Ran Yun's specific plan, Yi Shui slapped his thigh and sighed.

"Well, you kid just said no, if you had said earlier, I could have gotten you some water. ”

"Who are you going to get back? Uncle Shui, do you have a way to get the water back directly?"

"Of course, I'm also cultivating water attribute source qi! I can still do this. ”

At the end of the words, Yi Shui also took out a small blue bottle in his Rongkong Stone ring.

"This bottle is made of Rongkong Stone, and it is also a very precious water blue Rongkong Stone. ”

"This kind of bottle is used to hold water, and his role is to help transport water in those places where water is scarce, in fact, almost every water attribute cultivator will have this bottle on their body. ”

"As for the purpose of carrying this water, it is to prevent you from encountering an opponent with similar attributes, and you can use the water stored in it to help you fight. ”

Looking at the blue bottle in Yi Shui's hand, Xiao Tianxing's eyes were immediately full of little stars.

"It's amazing! Then second uncle, how many people can you hold in this bottle?"

"Well, I haven't really counted it, because the bottle is never full. ”

"But I estimate that if it is full, it should be enough for 2,000 people to consume water for a day!"

"Wow! It can hold so much water! Second uncle, where did you get this bottle?"

"Ah! This was given to me by a senior at the beginning. Unfortunately, when I met him, he died not long after he was seriously injured. ”

"Oh!

After lowering his head and thinking for a moment, Ran Yun raised his head and looked at Yi Shui.

"Well, with this bottle, you can fill the moat very quickly, but I think you need to prepare for a larger well. ”

"After all, we've been here for a long time, and the water in the moat will seep through for a long time. ”

"Well, that's exactly what you say. The places outside the fortress where there is abundant water have all been marked on the drawings. ”

"As for the water needed in the moat, I'll just go to the nearby river and use this bottle to get it. ”

Nodding at Yi Shui, Ran Yun also agreed with his approach.

"Well, then let's do it! Uncle Yishui, you arrange for someone to dig a well, and we will also speed up the speed to dig the moat. ”

After nodding at Ran Yun in agreement, Yi Shui also put forward his own opinion on him.

"I can help you with the matter of digging the well, and as for the matter of the moat, you should also hurry up. ”

"If you really can't do it, send more people, although you want to train yourself through this incident, but don't forget that this is the battlefield. ”

"The major events of the military aircraft are more important than your training, and the construction of the moat should be completed as soon as possible. ”

"Yes! I'll get the moat in order as soon as I can. ”

After Yi Shui returned to the Hung Tooth Fortress, the excavation of the fortress moat was also much faster.

Three days later, a moat more than 100 zhang long, two zhang wide and one zhang deep also appeared outside the fortress of Hun Ya.

With the help of Yi Shui and the joint efforts of everyone, after another three days, the moat was also filled with water.

After the work on the moat was completed, Ran Yun commanded the people to build a suspension bridge more than two zhang wide outside the city gate to serve as a way for the soldiers to enter and exit the fortress.

After completing the work of the moat, Ran Yun led people to use the soil excavated from the moat to build an earthen wall one zhang five feet high on the periphery of the moat.

After the construction of the earthen wall was completed, Ran Yun led people to dig a large number of pits outside the earthen wall.

Finally, outside these pits, Ran Yun once again led people to build a seven-foot-high earthen wall.

After almost a month of hard work, the fortifications on the perimeter of the fortress were completely completed.

After a month of high-intensity work, the children and soldiers who participated in the work have also greatly improved their physical strength and self-cultivation.

At this time, they all had a common hope to see how useful the fortifications they had built could be.

And such an opportunity also quietly came one night.

After three days of construction of the fortifications outside the fortress, everyone began their own practice and work after dinner.

After completing the necessary cultivation and work, except for the people on night duty in the fortress, the rest of the people in the fortress also rested.

As the lights gradually decreased, most people gradually fell asleep.

After everyone fell asleep, a small group of demon spirits outside the fortress also took advantage of the cover of night and quietly came to the edge of the fortification outside the fortress.

After carefully observing the surrounding situation, these demon spirits quickly climbed over the outermost seven-foot-high earthen wall.

However, just after climbing over this earthen wall, before they could take two steps forward, these demon spirits tasted the trap set by Ran Yun.

"Goo Dong! Goo Dong ......" With the sound of falling, the first group of demon spirits to climb over the earthen wall were defenseless, and all fell into the pit.

Although these pits were only a zhang deep, Ran Yun had people arrange them with cupola knives and Litian crossbows.

So after these demon souls fell into the pit, they were immediately pierced through their bodies by the iron awl inside.
