In the Thousand Swords Cliff.

Mu Lingxian was holding a long sword and constantly fighting with Chen Feng.

He has not long comprehended the sword intent, and he still needs to sharpen it to mature the sword intent.

The sword intent in the world that he has comprehended now is fundamentally still born from the Shihe Sword Dao in his previous life, so Chen Feng, the only one in the world who still has Shihe sword intent, is naturally the best object to sharpen.

I didn't expect that a disciple in a previous life would become a teacher in this life.

Mu Lingxian smiled slightly in his heart, relieved and at the same time, he also felt the wonder of fate.

At this time, neither of them used any magic powers, and only fought with sword intent.

If Chen Long had reached the pinnacle of kendo attainments in his previous life, he would naturally not lose to his disciples, but he was determined to start all over again, only to confirm the sword dao of his previous life in this life, and simply fight Chen Feng with the human sword intent he had just comprehended.

And over the years, Chen Feng has cultivated the Shihe Sword Dao that he has passed down to a few essences, and the sword intent is so strong that even when he was in the Emperor Realm in his previous life, Jia Shu can't compare to it, and the human sword dao that he has just comprehended can only barely resist the enemy.

However, he is also gradually improving, from the beginning of the barely resisting, gradually can already start to fight back gradually.

"Is this the way of the sword you comprehended?"

When Chen Feng took out his sword, he said in a deep voice: "Why do I feel that you haven't played all yet?"

Mu Lingxian smiled slightly: "It's not mature yet, so I need your help to temper it." ”

Half a day's time passed in a flash, and at this time, Mu Ling Immortal's sword intent confrontation with Chen Feng, who was suppressed in the Emperor Realm, was already almost equal, but he was slightly inferior.

"Teacher, it's almost time. ”

Mu Ling Xian suddenly took a step back, his left hand behind his back, and his right hand with a horizontal sword in front of him.

"My sword is called the world, please ask the teacher for advice!"

On the barren mountain, he comprehended the human sword path created by the true meaning of heaven and earth, and at this moment, he finally had to really exert it!

Chen Feng was silent, and a look of expectation flashed in his eyes.

At this moment, a sharp alarm suddenly sounded in the sky.

Both of them were shocked at the same time.

Chen Feng's eyes froze: "It's not good, there is a situation." ”

"You go back first, and then continue when I come back. He dropped a sentence and flew into the sky.

Mu Lingxian also reacted that this sharp siren was set up by himself in the past after the air defense alarm of the earth in the previous life, and it was used to warn the teachers and students in the academy when a critical situation occurred.

But when he was in charge of the academy, it never sounded.

Could it be that someone is attacking the Academy?

Leaving the Thousand Swords Cliff, Mu Lingxian found that the teachers and students along the way all looked calm, as if something had happened.

When I returned to the school building, I happened to meet Yuan Tianqi who came to the door.

"Do you know what's going on?" he asked, although Yuan Tianqi was only a second-year student now, he had always been very well informed, and he knew more about the current affairs in the academy than he, the former dean.

Yuan Tianqi gave him a blank look: "I really convinced you, why don't you know anything? This is the Hundred Domains Alert." ”

"Hundred Domains Alert?" Mu Lingxian said curiously.

After Yuan Tianqi's explanation, Mu Lingxian understood.

Since the outbreak of the demonic calamity, the entire continent and all regions have been in danger.

Unlike the Great War of the Hundred Clans back then, the Heavenly Demon invaded, and no part of the continent was truly safe.

Although the Invisible Heavenly Demon Lord was injured by the sword of Chen Long in his previous life and withdrew from the continent, there was also an army of true demons that erupted from the seal of the endless sand sea, as well as the primordial demons who had been lurking all over the continent long ago, preparing to break the seal.

Before this unprecedented disaster, even the Terrans and the Hundred Races who had just finished the Great War had to abandon their previous suspicions and fight against the Demon Calamity together. The powerhouses on both sides did their best, and barely blocked most of the Heavenly Demons and True Demons in the west of the continent, which was the front line mentioned earlier.

However, the demon race is invisible and cannot be completely blocked, and there is a possibility that a primordial demon will attack any part of the continent at any time.

Fortunately, most of the true demons above the Holy Realm will attack the base camp of the Terran forces. Most of the weak areas, such as the lower realms, are threatened by the ubiquitous magic golems.

However, this is not absolute, the strong man of the human race is an obstacle to the Demon Destruction Fighting Law Continent, so it needs to be solved first, but there are often true demons who bypass those powerful forces and directly attack those areas in the lower region where there is no strong person in the Holy Realm.

The power of darkness comes from destruction and nothingness, the more you destroy, the greater the power, an ordinary yin demon, after destroying a domain or more creatures, will also evolve to the level of an external demon, or even a heavenly demon.

This is the lesson that the Terrans have learned after decades of paying the price of the destruction of five lower realms and two small worlds.

However, the continent was so big, it was already extremely difficult for the two clans to maintain the front line, let alone draw out the Saint Realm powerhouses to sit in the Hundred Domains respectively.

Under such circumstances, the academy with the Boundary Gate and the Teleportation Array connecting the Heavens and Hundred Domains became the only way to stop the Primordial Demon from attacking the Lower Domain.

This is also the reason why in such a grim situation, several Sages have to be left in the academy. There must be a Sage staying in the academy and going to the Heavens and Hundred Domains to support through the Boundary Gate at any time.

Over the years, the two branch deans of the Heavenly Machine Master and Fu Xuanling have spent a lot of effort to set up all the outer teleportation arrays of the academy, which are enough to resist the attack of the Holy Realm True Demon in a short period of time, so as to support the strong people stationed in the academy when they rush through the boundary gate.

The Hundred Domains Alert is an alert to the academy headquarters when each domain is attacked or perceives a crisis.

Hearing this, Mu Lingxian couldn't help but nodded, slightly proud.

It was just a moment of arrogance that he set up the Hundred Domains Teleportation Array back then, and he wanted to accommodate the Heavenly Students, so he spent an unknown amount of money on it. However, there was a great war of the Hundred Clans, the invasion of the existing Demon Calamity, and the Hundred Domains Teleportation Array all played a vital role, and sure enough, his decision was still very wise.

However, he quickly came back to his senses, realized the problem, and hurriedly asked, "So, is there a lower domain that has been attacked by the primordial demon now?"

Yuan Tianqi shook his head and said: "It doesn't have to be a real demon attack, as long as it is suspected of encountering a crisis, it will issue a hundred domain alarm, but I heard that it hasn't sounded for several years." We used this method to stop the True Demon from attacking the Lower Domain several times, and it is even said that we even killed two primordial demons, and after that, they also learned to be obedient, knowing that this could not be done without our academy, so they rarely did this. ”

Mu Lingxian wanted to continue asking, but suddenly, the student ID card on his waist vibrate.

"All students from the fifth grade and above, hurry to the central square to assemble!"
