A quaint wooden box flew into Du Yu's arms, and Cai Jianlin's voice sounded from afar: "Take it, make tea for your sister!"

Looking at Cai Jianlin, who was anxious to go away, Liu Lang couldn't help laughing. It seems that the material problem has really bothered these people for too long, otherwise Cai Jianlin would not be so excited.

Cai Jianlin's purpose he also guessed, most of them were to find someone to partner with, after all, this is a big project, and the Cai family can't eat it.

"Thank you Cai Laozu! Thank you Brother Liu!"

Opening the wooden box and looking at the pale yellow chrysanthemums in the box, Du Yu was also excited and kept thanking him.

"Let's go! Let's go try it for Xiaorou!"

Back at Du's house, Du Yu took it upon himself to feed the tea brewed by Yangshen Ju into Du Rou's mouth.

Yangshen chrysanthemum looks unpretentious, just like ordinary chrysanthemums, but the effect is extremely significant.

Du Rou drank the tea for only a long time, and then opened her eyes in a daze, and her spirit was much better than before.

"Brother, what's wrong with me?"

Du Rou didn't know her own situation yet, and looked at Du Yu and Liu Lang standing in front of the bed, feeling very puzzled and awkward.

Du Yu cried with joy and hugged Du Rou tightly in his arms: "It's okay!

Seeing that the Yang Shen Ju was very effective, and Du Rou was much better, Liu Lang quietly left the room, leaving the space for the two brothers and sisters.

As soon as he went out, Liu Lang saw Du Wei leaning against the wall.

"Hmph!

Liu Lang smiled: "Then, do you want to be friends with me?

"The genius disciple of Tianxia Mountain, I can't afford to climb high!"

glaring at Liu Lang angrily, Du Wei turned around and left.

And Liu Lang walked to the place where Du Wei was standing and found that there was a small hole the size of a finger on the wall, just enough to see Du Rou on the bed.

"Knife mouth tofu heart, it's you!"

......

I don't know how Cai Jianlin discussed it with others, anyway, several Xiuzhen families in Yancheng all participated, and immediately started to act.

As a result, Yancheng was restless, and a large number of monks were recruited to start building railroad tracks along the four directions of Yancheng, opening holes in the mountains and building bridges in the rivers.

With a large number of monks, the construction of the railroad tracks was very fast, and in just one day, hundreds of miles were built, and it continued to grow.

"Look at it like this, it won't be long before the two places can be connected!"

"The train is also starting to be refined, and I believe it will be ready for use soon!"

On the hillside, listening to the words of Du Ruhai and Cai Jianlin's expectation, Liu Lang looked at the railway built below, which was indeed not much different from what he remembered, but he always felt that something was missing.

After recalling for a while, Liu Lang finally remembered that something was missing.

"You can lay some hard gravel under the rails!"

Liu Lang didn't know how this worked, only that it would be good for both the rails and the train.

Hearing Liu Lang's words, Du Ruhai and the others didn't ask anything, they immediately gave orders, and then looked forward to the future again.

Looking at the expectant look of the two, Liu Lang really couldn't bear to pour cold water, but another concern was like a fish in his throat, and he didn't vomit or feel unhappy.

"Two seniors! This can indeed solve your problems, but there will be a lot of people who are jealous, right?"

Hearing Liu Lang's words, Du Ruhai and the others were obviously stunned for a moment, and then smiled disappreciatively.

"Don't worry, nephew Xian! As long as there is no grudge, the four sects of Dao Buddha and Demon will not come to us for trouble!"

This title has changed, which shows that Liu Lang's status in the hearts of the two has improved a lot. However, Liu Lang cares more about the words of the two.

"Why?"

"Yancheng is remote and desolate, and there are few resources around, do you know why it still exists?"

Without waiting for Liu Lang to ask, the two explained one after another: "Because there is a dragon vein suppressed under Yancheng!"

"As we all know, the dragon vein is full of spiritual energy, but it is extremely violent. All monks who are contaminated with the aura of the dragon vein will all become violent and bloodthirsty. ”

"Therefore, thousands of years ago, multiple forces attacked at the same time to suppress and seal all the dragon veins in various places, so as not to let the aura of the dragon veins overflow. ”

"After the dragon vein was sealed, some monks volunteered to stay and guard the seal in case of accidents, and our ancestors were one of these people. ”

Liu Lang suddenly realized: "No wonder!"

He was still wondering before, in terms of the geographical location of Yancheng, there should not be a city at all, if this is the reason, it makes sense.

At the same time, he also understood why no one would come to trouble these families for no reason.

To put it bluntly, these families are paying for the entire cultivation realm, and bullying them is to be the enemy of the entire cultivation realm!

Cai Jianlin smiled bitterly: "They also persuaded us to leave and cut off our resource supply. But the ancestral precepts are difficult to disobey, and it is impossible for us to leave until the last resort, so we can only stay here!"

"Admire!" Liu Lang admired from the bottom of his heart.

They may have their own selfishness, after all, there is safety and security for staying here, but when it comes to a thousand things and ten thousand, they are all guarding the seal at the risk of great danger, so they are worthy of admiration!

Looking at the orderly construction project, Liu Lang was very satisfied and missed, but he was not ready to continue to delay here.

Since he left Tianxia Mountain, more than half a month has passed, and it is not far from the mission deadline of the Haotian Sword Sect.

As soon as he thought of this, Liu Lang hated Qiyuan River again. After he was attacked by Yuanhe and fell unconscious, he slept for nearly ten days.

Just as he was about to say goodbye and return to the city to see Du Yu for the last time, he suddenly felt a vibration under his feet, and then there was a loud earth-shattering sound below, and then countless exclamations sounded.

"What's wrong?"

Du Ruhai took Liu Lang and Cai Jianlin to fly down the hill and ask the panicked crowd.

"Two seniors, the front suddenly collapsed, and a deep pit appeared, and several Daoists were buried underneath!"

Liu Lang stepped forward and found that the pit was really deep, and he couldn't see the bottom of the pit, and it was pitch black.

Liu Lang shouted into the pit, "Is there anyone?"

The sound echoed through the crater for a long time, but no one responded.

"I'll go down and take a look!"

Du Ruhai flew down and slowly fell towards the bottom of the pit, but he quickly disappeared, and no sound came out.

After a long time, Du Ruhai did not return, Cai Jianlin began to be anxious, and shouted at the pit from time to time.

Two hours later, Du Ruhai finally came out of the hole, looking a little embarrassed, but he couldn't hide his excitement.

"Below is a cave mansion, covered by a formation! But it doesn't look very strong, and I don't know if it's been too long, or if the strength of the owner of the cave mansion is not high. ”

Hearing that there was a cave house below, everyone was excited, including Liu Lang.

As a monk, the most interesting thing is not to cultivate and entertain, nor to fight fiercely, but to explore the ancient caves, not to mention the excitement, the rate of return is still very high.

"Let's go!"

Liu Lang didn't know how the others went down, anyway, he was taken down by Cai Jianlin.

Speaking of which, Cai Du and the others were enough, and they didn't stop the others from going together, if they met other powerful monks, they would have cleared the field long ago, and there was nothing wrong with the weak at all.
