After breakfast, the eldest prince took the master and apprentice to a pavilion, "The Dragon Pool is inside, because there are regulations, you can only enter alone, so the Venerable is waiting at the door." ”

"Good. Meng Xue agreed, and then turned her head to look at Lin Xinhan, "Come in quickly, remember to soak in well." ”

"Got it, Master Cher. Lin Xinhan pushed open the courtyard door, glanced back at Meng Xue again, and said with a worried expression, "It's just that the apprentice doesn't know how long it will take to come out after entering this time, and the master can go to the neighborhood to enjoy it, and there is no need to wait for the apprentice here." ”

Seeing that the apprentice was a little uneasy, Meng Xue smiled and comforted, "Don't worry, didn't the emperor say it just now, it won't take long." ”

The eldest prince next to him also chimed in, "That's right, I went in once before I went down, and I was able to come out in less than half an hour." ”

"Okay. When Lin Xinhan heard this, he breathed a sigh of relief, and then walked into the courtyard.

As soon as Lin Xinhan came in, he felt that the aura here was abundant, and when he looked up, he was surrounded by hundred-year-old elixir spiritual plants, and in the center of the courtyard, there was a pool made of white jade, the pool was filled with mist, and there was a large amount of golden aura visible to the naked eye, for a while, Lin Xinhan thought that he had come to the fairyland.

Before coming to the pool water, Lin Xinhan stretched out his hand and put it into the pool water to feel it, and there was a wave of magic in his heart, it was winter now, but the water was hot.

Thinking that the master was still waiting for him outside, Lin Xinhan quickly found a suitable position, sat down cross-legged, and the warm pool water wrapped Lin Xinhan, making him relax quickly, but between breaths, he entered a state of concentration.

Lin Xinhan quickly felt that a gentle energy entered his body along the aura, slowly repairing his damaged foundation, and even some places where the meridians were blocked were also opened up under the washing of this energy.

In this way, Lin Xinhan was immersed in cultivation, and he didn't know how long it took, until he suddenly couldn't feel the supply of spiritual energy from the outside world, and then he slowly opened his eyes.

It's just that as soon as Lin Xinhan's eyes opened, he was shocked by the world in front of him, and all the familiar scenes before disappeared, and in their place, there was a black world full of eyes.

There was only black left around, and it was silent and eerie.

Lin Xinhan rubbed his eyes, the black color still did not change, as if what happened before was a beautiful dream, and now he woke up, and it was at this time that Lin Xinhan suddenly found that the aura in his body was completely inaccessible.

Why is this happening? Lin Xinhan wiped the cold sweat from his forehead and looked around, as if some desolate beast was staring at him in the dark.

Suddenly, he spotted a figure.

I don't know when a figure appeared in front of him, obviously he was in the dark, but he could vaguely see the appearance of that figure, it was a man, his face couldn't be seen clearly in the black fog, but the moment Lin Xinhan saw that man, every muscle involuntarily began to tremble.

This is the body's fear of the strongest, an imprint from the depths of the soul!

"Who are you?" Lin Xinhan looked at the man in front of him vigilantly, and at the same time, tried his best to suppress the trembling of his body.

"You don't need to know who this seat is, you just need to know that your next answer will determine your fate. The man said indifferently, just a voice, Lin Xinhan was unstable, and his soul was almost scattered.

"What does the senior want to ask?" Lin Xinhan shook his head, trying to drive away the roar in his mind.

"This seat asks you, are you willing to swear to this Heavenly Dao that you will spend your life to protect your master?" When the man said this, his tone was not as heavy as just now, which made Lin Xinhan feel a little better.

The oath of the Heavenly Dao is a promise made by the cultivator with the oath of the Heavenly Dao, once the oath is made, it cannot be violated, if it is violated, it will be full of demons, and it will never be recovered.

"Heavenly Dao Oath?" The unexpected question made Lin Xinhan's pale face appear with a touch of arc, "I will be good to her without being reminded by my seniors, so I don't have to worry about my seniors." ”

"If you don't swear, I'll never see your master in your life. The voice suddenly raised, and Lin Xinhan's body shook when he listened, and he almost spit out a mouthful of blood.

Trying his best to suppress a mouthful of fishy sweetness in his mouth, Lin Xinhan looked at the man with red eyes, "What do you want to do to Master?"

If he dared to hurt Master, he would definitely not let this man go!

Seeing Lin Xinhan glaring at him like crazy, the man nodded slightly, and his voice softened, "It's not your turn to dictate what this seat wants to do, you just need to remember that you are just an ant in the eyes of this seat, even if this seat wants to do something, you can only watch weakly." ”

"So, this heavenly oath, do you send it, or don't you send it?"

Glaring at the man fiercely, Lin Xinhan said solemnly, "I, Lin Xinhan, am willing to swear to the Heavenly Dao, as long as I don't die, no one can hurt Master Xue'er, if I disobey, my soul will be destroyed." ”

As soon as the last word was finished, a layer of pale gold appeared on Lin Xinhan's body, obviously, Tiandao had already acknowledged his oath.

"Remember your vow today, if you dare to live up to her, there will be no place for you at the ends of the earth. After the man finished speaking, he retracted the coercion, raised his right hand, and a little black light flew out from his fingertips, and quickly disappeared into Lin Xinhan's eyebrows.

Lin Xinhan was taken aback by the man's action, and hurriedly felt his body, but he didn't feel any discomfort, so he was a little relieved.

Seeing this, the man chuckled, and then said, "What I taught you just now is a technique that transcends the Heavenly Rank. ”

Really? Fake? Lin Xinhan touched his eyebrows, a little incredulous.

The martial arts of the cultivation realm are divided into four classes of heaven and earth, Xuanhuang, and each level is divided into upper, middle and lower grades, for so many years, Lin Xinhan has never heard of any exercises in the cultivation realm that surpass the heavenly level, no wonder he can't believe it.

The man saw that Lin Xin was cold and didn't believe it, so he bewitched, "If you can't grow up quickly, you won't be able to protect her, and this exercise can quickly improve your strength." ”
