The "Four Saints Academy" was an ancient academy located in the heart of the Mountain Range of Death. For thousands of years, countless peak-level powerhouses of the Monster race had walked out from this place.

The difference was that one belonged to a human, while the other belonged to a demi-human. They were born with brute force, but their intelligence was lacking, especially in the presence of the mirror, while the Four Spirit Academy, although they had the reputation of being the number one academy on the continent with a sword on their shoulders, did not dare to rashly provoke the Four Spirit Academy. This proved just how formidable the background of the ancient school that was as famous as the Four Spirit Academy was.

In the eyes of the demons, the Four Saint's Academy is the Four Spirit Academy in the eyes of the humans, and its influence has never been greater. The scariest thing about a school is not how strong its teachers are, but how many experts can leave the academy one day. If the Four Saint's Academy were to be struck by a destructive attack, and how many powerhouses would be summoned back, it would be hard to imagine just how spectacular that scene would be.

As the only city in the Mountain Range of Death, the Four Sacred Cities possessed immense power and after a thousand years of development, they had basically become a demon empire. The only difference was that the power here was extremely complex, with countless demon clan forces participating in it. Perhaps, an inconspicuous old man by the roadside had an astonishing background.

The distance between the Four Spiritual Academies and the Four Sacred Grounds was extremely vast. It would take over half a day to travel from the Four Spiritual Academies to the outskirts of the mountain range of death, and not even two or three months after entering the mountain range of death, you wouldn't even be able to reach the Four Sacred Academy. If you entered the mountain range of death without any Demonic Beasts attacking you, then normally, the outer perimeter of the mountain range of death would be filled with mirror shaped Demonic Beasts.

Fortunately, Old Fu would notify him in advance every time they traveled, which allowed Gu Lin to arrive at the Sacred City and leave the inaccessible land. After about half an hour of flying, the mountain range below them became extremely wide, causing Gu Lin to be stunned for a moment. Then, he raised his head and swept his gaze forward, only to see that at the end of his line of sight, the mountain range of death, which was originally as green as jade, was separated from the world inside by a thick wall.

"So this is the Sacred City of the Four Sacred Cities?" The corner of his mouth curled upwards and a smile as if he had been relieved of a heavy burden spread out from the corner of his mouth. According to what Elder Fu had said, this wall was the fences of the "Four Sacred Grounds". As long as one stepped inside, they would have completely entered the world of the demons.

"We're finally here." Gu Lin said softly before slowly descending. Although the "Four Sacred Cities" were right in front of him, he did not immediately choose to enter. Old Fu had always emphasized that the Monster race respected the strong. In that case, entering a world filled with demonic beasts in his current tiredness did not seem like a wise decision.

"Recover your Spiritual Energy first. It has already been hard on you for two months. This trip to the Mountain Range of Death has made your Azure Dragon energy more stable and your Spiritual Beast Transformation much easier." Old Fu's voice sounded in his heart.

"Alright!" Gu Lin responded and slowly landed at the foot of the wall. He quickly investigated for a while and after not discovering any demon beasts, he finally relaxed and sat cross-legged. A wave of talking Spiritual Energy spread out.

As Gu Lin entered his cultivation state, faint Spiritual Energy began to seep out from his body. The surrounding faint Azure Dragon Spiritual Energy was accompanied by Gu Lin's aura, and as it went in and out, it was started to be absorbed. As the Azure Dragon Spiritual Energy was absorbed, Gu Lin's complexion improved.

Changing the night from day to night, this kind of training continued for almost two whole days. The faint green dragon Spiritual Energy around Gu Lin's body gradually weakened and finally dissipated.

Frowning slightly, he slowly opened his eyes and an azure-green dragon shadow flashed across his eyes. Within his deep gaze, an azure-green aura surged out and there was the sound of an explosion. The Spiritual Energy waves caused by Gu Lin spread out violently.

Gu Lin raised his head to look at the spreading Azure Dragon spiritual energy and slightly opened his mouth. 'I broke through just like that?'

"Sure, young man!" "A sixteen year old Mastery Stage cultivator, not bad, you didn't run away in vain these past two months." Looking at Gu Lin's shocked face, Old Fu couldn't help but laugh.

Gu Lin nodded his head in satisfaction. He swung his arm and watched as the green dragon's spiritual energy quickly dissipated. In the past two months, he had not been on the brink of death.

"Enough, don't be too complacent, brat. I don't need to explain to you how many geniuses there are on this continent, but how many are going to be on the historical stage? Wasn't that expert experiencing life and death situations behind him? Entering the "Four Sacred Cities" in your current state is an additional safeguard. "Old Fu stroked his remaining beard as he stood in front of Gu Lin and looked at the Four Sacred Cities.

"Got it, Old Fu." Gu Lin nodded, stood up with both feet, and said, "Then we're entering the" Four Sacred Cities "now?

"En!" However, I have to remind you this: in the "Four Sacred Cities", there is still a difference between using "Spirit Dragons Transformation" and using "Spirit Dragons" as little as possible, after all, compared to using "Spirit Dragons Transformation", there is still a difference between using "Spirit Beasts" and "Spirit Dragons Transformation".

"No way!" Gu Lin was stunned. After a long while, he smiled bitterly and said, "I thought I could transform into a beast at any time over here. That way, it would at least guarantee that I would have the strength to fight against a Spirit Gathering Realm cultivator.

Haha, boy, as long as you maintain your human form in the "Four Sacred Cities", ordinary demon beasts would not provoke you. After all, those who can transform into human form are all Spirit Gathering level demons, and those below the Spirit Gathering level would not act against you if they had low intelligence. The experts in the Spirit Gathering Mirror are usually the management of the various forces. Elder Fu laughed heartily. "Alright, youngster, let's go. Let's see if the Four Sacred Grounds is truly like the legends, a heaven for demons.

Hearing this, Gu Lin smiled. Weren't they being chased after?! Hearing Old Fu's words, Gu Lin let out a sigh of relief. He tidied up his clothes, picked up his spear, and like an arrow shot from a bow, transformed into a cyan dragon as he dashed towards the gate of the Sacred City.

"Four Sacred Cities, I hope you won't let me down."
