Lu Chen did not hesitate, and as soon as his mind moved, a mist-shrouded, divine and majestic dragon gate appeared at the center of his eyebrows. As soon as the majestic Dragon Gate appeared, there was a breath of antiquity and vicissitudes revealed. Then the dragon gate slowly opened, revealing the sea of knowledge hidden behind it.

During the battle with Ding Ling, at the last moment, Lu Chen combined the power of knowing the sea with the fire proverbs of the Nine Dragons Proverbs, imagined and constructed a huge flame dragon, and finally killed Ding Ling. However, his sea knowledge was also exhausted because the flame dragon had drawn too much power to know the sea, but at this moment, Lu Chen found that his sea knowledge had recovered to the size of ten acres, and the power of sea knowledge was like rippling waves.

I didn't know how to cultivate to replenish the power of sea awareness that was consumed, so naturally I didn't deliberately cultivate. Now that Zhihai is full of energy, it is obviously related to the fact that he has slept and got enough rest. Thinking of this, Lu Chen's sea of knowledge rippled with the birth of his own mind.

Seeing this scene, a touch of surprise appeared in Lu Chen's eyes, and at the same time, there was a wave in his sea of knowledge.

"The thoughts in my heart will actually react in the sea of knowledge!" Lu Chen said in surprise.

Seeing this, Gu Linglong glanced at Lu Chen, and said indifferently: "Zhihai is a combination of spirit and thought, as soon as your mind moves, Zhihai will naturally react." ”

"In this case, as long as I have thoughts and thoughts in my heart, or all the thoughts and thoughts in my heart, they will be manifested in the sea of knowledge? If other people have also cultivated the sea of knowledge, wouldn't it be easy to spy on the changes in other people's minds. Lu Chen asked the doubts in his heart.

"First of all, knowing the sea is a collection of spirits and ideas, and if a person thinks about it, his knowledge of the sea will naturally react. However, this is not uncontrollable, it's just that you have just opened up the sea of knowledge, and you have not yet truly mastered your sea of knowledge. Secondly, after cultivating the sea of knowledge, it is even more difficult for others to spy on what you are thinking, because there is a portal blocking it. ”

Pointing to the dragon gate in front of Lu Chen's eyebrows, Gu Linglong continued: "The portal is not open, and the sea is not visible. And if others want to spy on your sea of knowledge, the first step must be to find your sea knowledge portal, and then open your sea knowledge portal. If you don't lose consciousness, even if someone sneaks up on your portal while you're asleep and wants to open your sea of knowledge and spy on its secrets, you can find out immediately. ”

Lu Chen nodded slightly, knowing in his heart. The reason why their thoughts and thoughts will be expressed one by one in Zhihai is because their control of Zhihai is not proficient enough. It's like a baby who has just learned to walk, and although he can walk, he is prone to fall when he walks, and the baby can't control it. However, when the baby really grows up, unless it is tripped by someone, it generally does not fall easily, which is mastery, and it is now equivalent to the baby just learning to walk. And worrying about others snooping on their own knowledge of the sea is simply redundant, there is a knowledge of the sea of longmen, once someone wants to spy on their own knowledge of the sea, they can immediately find out and fight back.

"You have already used the power of the sea to perform the Nine Dragons Proverb once, and now try to run the Proverb of Fire again, and use the power of the sea to send out a flame dragon, let me see what you are lacking. Gu Linglong said.

If you do it again, I'm afraid that your power to know the sea will be exhausted again. However, Lu Chen didn't think much about it, nodded when he heard the words, and then ran the Proverb of Fire, and at the same time, the power of sea knowledge poured out from the dragon gate. Lu Chen secretly realized that when he used the power of sea knowledge, there was indeed an inexplicable fluctuation in the void. Before, it was this inexplicable fluctuation that woke up the sleeping Gu Linglong. It seems that mobilizing the power of knowing the sea in the sea of knowledge and mobilizing the true qi in the sea of qi are the same situation, and there will be different fluctuations, and it is impossible to be silent.

"Throat—"

With a high-pitched dragon groan, I saw a small fire dragon similar to the thickness of his fingers soaring out of Lu Chen's Zhihai Dragon Gate and slaughtering forward. As soon as the little fire dragon appeared, it was like blowing up a balloon, rising in the wind, and the dragon's head instantly swelled to the point that it was about the size of a water tank. At this time, the dragon tail of the little fire dragon had just broken away from the Zhihai Dragon Gate.

The power of knowing the sea is like a lake, and the little fire dragon is a round of flames scorching the sun. When the sun shines, the lake is evaporated at a rate visible to the naked eye. As the power of sea knowledge in the sea was violently consumed, the little fire dragon also underwent obvious changes, from a cute and small little fire dragon to a flaming fire dragon full of terrifying majesty.

The head of the Flame Dragon was huge, its eyes were like lanterns, and its two long dragon whiskers danced in the wind, sweeping over Lu Chen's cheeks.

And at this moment, a familiar feeling came again, Lu Chen's body trembled violently, his face was pale, his head was even more drowsy, and he only felt that the world was spinning, and his body was extremely weak. With a loud bang, the Flame Dragon swooped forward, hitting a large tree several feet tall in front of it, and after a while, the tree disappeared along with the Flame Dragon.

"Still can't work!" Lu Chen sighed, and then couldn't support it anymore, sat on the ground with his ass, and gasped.

Seeing this scene, Gu Linglong was slightly stunned, suddenly thought of something, stared at Lu Chen, and asked, "How long did it take you to open up the sea of knowledge?"

Lu Chen thought about it seriously and said, "It's about more than six hours." "Fortunately, when Gu Linglong blocked the entrance of the cave before, he left a breathable gap, and through the change of light, Lu Chen could grasp the passage of time, otherwise Lu Chen really didn't know how long it took him to open up the sea of knowledge.

As soon as Lu Chen said this, Gu Linglong's mouth opened slightly, looking surprised. Lu Chen opened up the sea of knowledge, and it only took more than six hours. Gu Linglong's mind flashed back to the situation when she opened up the sea of knowledge, and it took a month just to find the gateway to the sea of knowledge. As for himself, but he is a dragon clan with pure blood! Glancing at Lu Chen, a trace of jealousy appeared in Gu Linglong's eyes, how could this shameless Terran boy have such a high talent, he is really more human than a dragon, and he is angry with a dragon.

Gu Linglong just taught the secret method to Lu Chen, thinking that it would take a long time for Lu Chen to find the gateway to the sea of knowledge, and it would take even longer to cultivate the sea of knowledge, but it didn't take long for Lu Chen to open up the sea of knowledge. And after opening up the sea of knowledge, she directly comprehended the power of knowing the sea and the use of the Nine Dragons Proverbs, which is really more demonic than her, the dragon girl, is it possible that a random human boy has such qualifications and understanding?

"It must be because of the relationship between the soul fruit, if I had the soul fruit to take at that time, I would definitely open up the sea of knowledge faster than Lu Chen. There is also the power of knowing the sea combined with the Nine Dragons Proverbs, but it was just Lu Chen's mistake. Gu Linglong said in her heart.

"What's wrong?" Seeing that Gu Linglong's face was not quite right, Lu Chen asked in surprise.

"Hmph~~~ This dragon girl personally taught you the secret method of the dragon clan to open up the sea of knowledge, and there is a top heaven and earth treasure like the soul fruit to assist your cultivation, it took you more than six hours to open up the sea of knowledge, your qualifications and understanding are really too bad! Gu Linglong pouted and said, she is a dragon girl, how can she take the initiative to admit that her understanding is not as good as that of a shameless Terran boy.

"If you exclude the time it took to recover from your injuries, it would have taken less than three hours to open up the sea of knowledge. Lu Chen said weakly, his heart was worried, the time was shortened by half, and he didn't know if his qualifications and understanding could enter the eyes of Gu Linglong.

The girl's volley figure staggered for a while, and said with a cold face: "It's still very bad, and I can't catch up with this dragon girl even if I shoot a horse." ”

Hearing this, Lu Chen's eyes were gloomy for a while, it seemed that the gap between himself and Gu Linglong was really not ordinarily large, I am afraid that there was a world of difference.

Seeing Lu Chen's eyes gloomy for a while, Gu Linglong's heart was a little unbearable, and she said weakly: "Although your qualifications and understanding are not as good as this dragon girl, it is already very good to be able to open up the sea of knowledge, don't worry about how much time you have used, remember, diligence can make up for it." Now listen attentively, and I will teach you how to truly control and use the power of sea knowledge in the sea of knowledge. ”

As soon as Gu Linglong said this, Lu Chen's eyes became invigorated again, he had not really mastered the power of knowing the sea, and the Flame Fire Dragon could exert the power of the martial arts cultivator who killed the six heavens of the Qi Sea. When you really master the use of the power of knowing the sea, and then run the Nine Dragons Proverbs, I am afraid that your strength will skyrocket once.

"Mastering and using the power of knowing the sea can greatly improve your strength, and it is also a life-saving hole card, you must cultivate well!" Lu Chen said in his heart.

"No movement, no stillness, no thought, no thought, the intention comes from chaos, and the innate aura is ......" Gu Linglong told the dragon clan about the method of knowing the sea.

Lu Chen listened attentively, and at the same time secretly thought in his heart, as long as he encountered something he didn't understand, he would ask Gu Linglong.

After a while, Lu Chen pointed to the dragon gate in front of his forehead and said, "Linglong, if you say so, the Zhihai Portal is a bridge connecting Zhihai and the physical body, right?"

Glancing at Lu Chen in surprise, Gu Linglong nodded and said, "You are right, the Knowing Sea Portal is indeed a bridge connecting the physical body and the Knowing Sea!"

After that, Gu Linglong continued to teach.

Not long after, Lu Chen asked again: "Zhihai moves with his heart, can it be ever-changing? A person's Zhihai can be ten acres of lakes, or ten acres of fire, or even ten acres of woods, rocks, and flowers......" While speaking, Lu Chen's knowledge of the sea changed into ten acres of fire, but soon, Lu Chen's mind moved again, and the knowledge of the sea returned to the original state.

Glancing at Lu Chen in surprise again, Gu Linglong nodded.

The teenager and the girl were in a hurry, while cultivating, asking and answering, and time passed slowly. As for the questions raised by Lu Chen, at the beginning, Gu Linglong was able to give detailed answers and explanations one by one, but as his cultivation deepened, the questions raised by Lu Chen became more and more in-depth, and even Gu Linglong had to think for a long time before he could answer. And in the end, the question raised by Lu Chen directly asked Gu Linglong to the dumb fire.

"Hmph~~~ Master led the door, cultivation is personal! You can't expect me to answer for you one by one, you have to have your own thinking and understanding, so that you can make progress. After once again failing to answer Lu Chen's question, Gu Linglong pouted and said.

"Makes sense. Lu Chen nodded seriously, and then pondered.
