Because they were not in a hurry, they did not venture through the Burial God Swamp again, but chose to return to the Heavenly Throne Academy from the official road.

About ten days later, the group finally arrived at the Heavenly Academy, Gu Tengfeng went directly to the mission hall to deliver the task, Yun Yiyi accompanied Lin Xian'er back to the residence, as for Ling Feng and Jiang Xiaofan, they also returned to the Tianshu East Courtyard, ready to rest and rest, so they went to the Elixir Garden to find Yan Cangtian.

Although it was difficult to get the token that determined that the ghost-faced demon lord Lin Canglang had died, it was difficult to get the reward of the demon slaying task, but it was not for nothing.

Jiang Xiaofan got the Xuanwu Treasure Blood and was completely reborn, and as for Ling Feng, he also got a Ten Thousand Evil Poison Fruit.

I believe that after Yan Cangtian saw the Ten Thousand Evil Poisonous Fruits, he would probably go crazy about it.

After returning to the Tianshu East Courtyard, Ling Feng first took a beautiful bath, said hello to Jiang Xiaofan, and went straight to Yan Cangtian's Elixir Garden.

This time, I left directly for more than ten days, and I don't know if Yan Lao is still in the study "retreat".

After a while, Ling Feng came to the elixir garden and found that the things in the courtyard, how he walked and when he came back, they were all exactly the same, and they were even covered with some dust and cobwebs!

It seems that during the time he left, Yan Cangtian never walked out of the study at all!

"I can understand how Yan Lao completed the "Medicine King Sutra" back then, and the degree of concentration is really embarrassing!"

Ling Feng shook his head and walked towards the study in the side hall, and before he could enter the study, he heard an excited shout from the courtyard.

"Found it! The old man finally found it! Hahaha......"

Obviously, that shout was made by Yan Cangtian.

Ling Feng touched the bridge of his nose, his body flashed, walked to the door, gently pushed it open, and saw Yan Cangtian in the study, his hair was scattered, the whole room was in a mess, and countless books were placed indiscriminately throughout the room.

The most exaggerated thing is that Yan Cangtian's two eye circles are as black as a giant panda, with his half-step emperor's realm, he is full of energy, far beyond ordinary people, and as a result, he has boiled out such dark circles, it is conceivable that this guy has not rested since he sat in the study.

At this moment, Yan Cangtian held a thick scroll and laughed: "Finally found it! Hahahaha! The old man has finally found it!"

Ling Feng gently pressed his temples, and while cleaning up the scattered books in the room, he asked with a wry smile, "Old Yan, what did you find?"

"Ling Feng kid!" Yan Cangtian noticed that Ling Feng had returned, and immediately jumped out of the stack of books, patted Ling Feng on the shoulder and laughed, "You kid, didn't you go to participate in some demon slaying mission, and you came back so soon?"

Ling Feng's head darkened, "I said Yan Lao, it's been more than half a month!Do you think this is yesterday?"

"Half a month?" Yan Cangtian brushed the hair in front of his forehead and grinned, "No matter what, Ling Feng boy, you came just in time!"

Thanks to Yan Cangtian is a half-step emperor, the Dao body has reached the realm of being dust-free and not eating grains, otherwise, if you don't take a bath or change your clothes for such a long time, you may become something stinky.

However, Ling Feng could still see that there were several cobwebs on this guy's hair, and he had to focus on how much he didn't even know if his head was webbed.

Ling Feng frowned and said with a wry smile: "Old Yan, it's not too late for you to take a bath a little." ”

"No need!" Yan Cangtian excitedly grabbed Ling Feng's arm, walked directly to the desk, and laughed: "Boy, after my painstaking research during this time, I have summarized all the examples of non-emperor-level powerhouses who can come back alive after entering Heavenly Demon City, and finally found a way for you to be able to sneak into Heavenly Demon City safely!"

"Oh?" Ling Feng's eyelids jumped, and he looked at the books on the table.

"Experiences in the Demon Domain", "Travels in the Demon Domain", "Monsters in Southern Xinjiang", ......

The relationship is good, all the books are related to how to enter the demon realm.

Ling Feng was secretly moved in his heart, looking up at Yan Cangtian, a warm current surged in his heart.

"Look at what!" Yan Cangtian punched Ling Feng in the chest and pouted, "Listen attentively to what I say." ”

"Hmm. Ling Feng nodded heavily, already regarding Yan Cangtian as his teacher, a lifelong teacher.

"Since the establishment of the Tianbai Holy Dynasty, to the present Tianbai Empire for six hundred and twenty-one years, a total of more than 1,600 years have been experienced, and the southern Xinjiang generation has always belonged to the realm of the demon race, but the strong men of the human race, for various reasons, will still enter the demon domain, so they have glimpsed some secrets within the 100,000 mountains. ”

"Among them, most of the people who can come back alive after entering the Heavenly Demon City are naturally emperors, emperors, masters of this level, flying to the sky and the earth, omnipotent, even if they are discovered by the strong people of the demon clan, they also have the ability to escape, not to mention this. Although I am also a half-step emperor, compared to the real emperor, although it is half a step behind, it is a world of difference. ”

Ling Feng pouted, his current situation was to bring a cheap donkey, coupled with Yan Cangtian's protection, I am afraid that he would not be able to retreat after entering the demon domain.

"Except for the kind of master who can invade the Demon Domain with his strength, for more than a thousand years, there are only two people who have been able to arrive in the Demon Domain alive and come back alive!"

"Two of them!" Ling Feng's pupils shrank slightly, and he swallowed with difficulty, "Which two?"

Yan Cangtian smiled mysteriously, "The second person, you should be more familiar with it, because this person is the deceased Medical Saint, Ling Hanyang!"

"My grandfather!" Ling Feng exclaimed.

"Yes, twenty years ago, an old demon emperor in the Heavenly Demon City was infected with a vicious disease, so he sent a master of the demon clan to invite your grandfather to the Heavenly Demon City for treatment. ”

After that, the old demon emperor's strange illness was cured, and he also kept his promise, promising that during his lifetime, the subjects of the clan would never step out of the demon realm, and also sent the medical saint back to the Tianbai Empire. ”

Yan Cangtian said, a hint of admiration flashed in his eyes, "Although twenty years have passed since this incident, but now that I think about it, the old man really doesn't have the courage of your grandfather, and I am ashamed of this." ”

"Grandpa!"

Ling Feng clenched his fists, and a sense of pride arose in his chest, because Ling Kun once said that although his grandfather's medical skills were good, he had never set foot in martial arts, an ordinary man, he actually dared to enter the demon realm alone, his courage was really admirable!

"Your grandfather is worthy of the word 'medical saint'!"

Yan Cangtian turned around and patted Ling Feng's shoulder, looking at Ling Feng deeply, as if looking at a former medical saint.

He wanted to surpass Ling Hanyang in alchemy all his life, but unfortunately, until Ling Hanyang passed away, he didn't have the opportunity to see this medical saint, which was also a big regret in Yan Cangtian's heart.
