Chapter 405: Anyone who crosses this line will die.

It was daytime when Lin Du came out. When he heard the noise at the door, Xia Tianwu had already arrived.

In her hand she was holding a bamboo sieve with some strange grass seeds dried by the shade in it. Her features were clear as she walked towards them under the green shade, like a spring in the forest, quiet and clear.

"Junior Master? Your retreat is over? So quick."

Lin Du raised his eyes, "Not fast, it's been three years."

Three years may pass in a flash for those who practice cultivation, but for Lin Du, it is not a short time.

"I've almost finished learning, but recently a new wave of evil demons has arrived. This time it seems that they were not driven out, but a planned invasion by the evil demons. Mo Lin is now stationed in front of the border of Zhongzhou."

Xia Tianwu saw Lin Du's eyes wandering around the yard, so he began to explain.

Lin Du's eyebrows moved slightly, "Evil demon invasion?"

Xia Tianwu nodded, "Master Uncle and Junior Sister are still at the northern border. It is said that demons are invading there in droves."

"Got it. I'll go make peace with Mo Lin first and deal with those evil demons."

"Hey, Junior Master, take your pulse first!" Xia Tianwu stopped her.

Lin Du subconsciously wanted to run, but when he remembered that he was almost fully recovered now, with even blood turning into blood on his palms, he stayed where he was and let her take his pulse.

Xia Tian Wu Zai carefully felt the pulse, and his expression became more serious. Finally, he came to a conclusion, "There is indeed no Yin Qi or serious illness. The heart pulse sounds the same as that of an ordinary person, but the inner pulse is still broken. The Yang Qi is a little too heavy. Although it has been refined, it is a little too much. It needs to be cooled down."

Lin Du cautiously probed, "So am I healed or not?"

Xia Tianwu replied, "It's fine, but not completely. It's gone in a flash. I still need to take medicine."

Lin Du was at a loss, "Do you still want to take medicine?"

"Master looks fine on weekdays, but he is easily seriously injured. He is like a glass man. He can move around normally without any problem, but once he is injured, he is easily seriously injured and healed slowly. He cannot stop taking medicine."

The light that had just ignited in Lin Du's eyes was shattered just like that.

“Young Master-Uncle should be used to it, why is he still so bitter and resentful? It turns out he is still young…” Xia Tianwu no longer had any grudges in his heart, and he didn’t completely regard Young Master-Uncle as an elder, but as his own patient, and he habitually controlled Lin Du.

Lin Du was fooled. "It's just a drink of medicine. I'm used to it. Come on!"

In the summer, I ran to boil medicine unsatisfactorily. The medicine must be boiled while it is hot, so that it will be most effective and heal faster.

Lin Du was fed numbing medicine for three days before he arrived at the southwest front.

Mo Lin alone was able to defeat hundreds of people, but facing the evil demons who had greatly increased in strength and were clearly obsessed with killing, he was still unable to handle the situation alone.

No one was injured, but they were almost unable to hold the line, and many evil spirits were lost.

The long sword had been unsheathed long ago, and the black thunder was violent and rampant, intercepting many evil demons. Behind him, there were many Feixing Sect monks who were dealing with the evil demons that broke through Mo Lin's front line one by one.

“Junior Master, you set up the formation, I’ll go and help!” Xia Tian Wuyi knew that Lin Du was here to set up a defense line, so he rushed to the front without saying a word.

Lin Du responded and raised his hand to force out a zero-point line. A line of ice and snow appeared in the southwestern border where there was little ice and snow. The power of ice and snow suddenly emerged from the ground like sharp icicles, directly piercing through the evil spirits on the line from bottom to top.

"Anyone who crosses this line will die."

The calm voice was spread forward by spiritual power, causing all the demons to freeze for a moment.

"Is that... a cultivator in the middle stage of Qianyuan Realm?" The elder of Feixing Sect was stunned for a moment, then he clenched the magic weapon in his hand, raised his head and looked at the evil demon who was hesitant to move forward due to the line, and suddenly he felt some confidence.

"The cold stars falling from the sky can repel thousands of evil demons! All disciples of the Feixing Sect, get to the front of the formation and hold this line!!"

The man who was once described as the Star of Temptation by the "elder" of the Flying Star Sect did not care about the inspiring words that were made up on the spur of the moment, and was already carrying his things to set up a defensive formation.

The Gu villages in the southwest are scattered, the towns are a mix of good and bad people, and the Feixing Sect has very few formation builders. It is difficult to build a defense formation for such a long border.

Mo Lin held a long sword in one hand, his body shape constantly changing, raising his hand to fend off a group of evil demons. Feeling that the spiritual energy in his body was about to run out, he hurriedly took out the Soul-Restoring Pill from the storage ring with his other hand.

There were more than ten bottles when I came, but now there is only one left.

He stuffed a handful of it into his mouth, not bothering to refine it. Just as he was about to rush forward, a stream of red fire sword energy with a snake-like arc swept away the evil demon in front of him, but there was a crackling sound, and the demonic energy surged out instantly.

Faced with such sword energy and power, Mo Lin's eyelids, which could hardly lift up, suddenly regained strength and his eyes widened.

"Junior sister!!"

A moon-white figure blocked in front of him, "Brother, step back, refine the medicinal power first, and leave it to me."

It was dark and then light again. After a night passed, the monks were exhausted. Then, a golden arc of light rose from behind their battle line, which made them burst into tears even more than the sunrise just now.

Just when the golden light was about to go out, an evil demon flew over and made the golden light light up again. With a crackling sound, the monks looked back and saw that the evil demon was directly blown up by the power of the defense array, and it was obvious that it was dying.

“Wow.”

Lin Du stood in front of the battle line and called out to Mo Lin and Xia Tianwu, "Let's go. We have a defense line now. If the Feixing Sect monks can't deal with the evil demons that have broken in, then our rescue will be in vain."

They came silently and left like a gust of wind.

The spiritual energy here is already dense, and it would be even more difficult in those border areas where the spiritual energy is thin. Without the power of a large sect, it would be easier for evil spirits to break through.

In the small courtyard of Fenghuang Town, Granny Ma thought that the two men had left and would never come back, but she didn't expect that they would come back one night later. However, they didn't treat this place as their own territory as before. They didn't just pick a room and go in. They just sat in the courtyard to relax.

"Didn't you leave? Why are you back?" Granny Ma was particularly disgusted.

Xia Tianwu spoke first, "You are also my master, how can I not come to pay my respects to you?"

Granny Ma snorted, "You righteous disciples are just strict in observing the rules, and you clean up these false things."

Lin Du raised his eyebrows. "When I deployed the formation, I asked the village chiefs on the border to swear to control the people in the village and not let the insects escape and harm people at will. Otherwise, I would not take their village with me when I deployed the formation, and this rule must be passed on to every village chief."

It would be troublesome for everyone to swear one by one. If there is someone supervising, we can find the leader when something goes wrong, and it will be much easier to manage.

Granny Ma's expression changed slightly when she heard this. She tilted her head and pursed her lips, "What does this have to do with me?"

Lin Du stood up and said, "We are really leaving. This time we are really leaving."

Granny Ma waved her hand and said, "Hurry up, hurry up, do you want me to prepare a table of wine for you to see you off?"

The three of them stood up, stood side by side, and saluted solemnly.

"Take care of yourself. If you need anything urgently, please send a message to us immediately, or contact the Supreme Sect. We will certainly come to help." Mo Lin promised earnestly, "We, the disciples of the Supreme Sect, will never forget any of your teachings and kindness."

Granny Ma stood there, her body hunched, looking at the three figures in front of her that were bent almost parallel to the ground. Her eyes moved slightly, and after a long moment, she said, "My skills don't require you. Just remember to give me a copy of your book when you finish it, Xia."

Xia Tian answered without hesitation, "Don't worry!"

Mo Lin spoke again, "You are the elder. We will send you gifts and letters during important festivals. If you are willing, you can also come to our Dingjiu City for a visit."

Granny Ma was not quite used to it. "What elders? I don't have any children. What kind of messed up relationship is this? You want me to pay for it?"

The two people's faces turned red. Lin Du turned around and waved his hands, "Then you wait. I've told you, if you're not at their desk, I'll come and invite you personally."

So don't be too quick to think about drinking the water from the Styx.

Granny Ma looked at Lin Du's graceful back, then suddenly turned her head and glanced at her crooked chair.

What a bastard! He left her a bunch of things to sort out before leaving.
