The smoke waves are vast like a vast ocean, among which there are seven pillars of heaven and earth that go straight into the clouds, directly cutting off the past clouds, and the endless aura of heaven and earth is pulled and gathered, where the aura is so dense that it almost turns into water mist droplets, and the seven pillars of the gods are transformed into different seven colors, gold, green, blue, red, yellow, cyan, white, and the seven colors represent the seven completely different elemental attributes of gold, wood, water, fire, earth, wind and thunder.

This is relying on the incomparably profound magic circle coupled with the blessing of incomparably powerful spiritual power to forcibly gather the aura floating between heaven and earth and form a space of its own for many disciples to cultivate, such a big stroke, even the knowledgeable Lin Yu was almost shocked to speak, he once again had a deeper understanding of the foundation of Xuantian Sect.

"This is the Spiritual Illusion Realm?" Lin Yu asked after a long time.

"Well, it's amazing, right?" Tang Guoyan said with a smile.

"Amazing, indeed very powerful, I have never seen such a magic skill, who is this magic circle from?" Lin Yu asked.

"It was the Sixth Elder Xuanjin Grandpa who set up the formation with his own hands, and then gathered the spiritual power of his father and the Seven Great Elders to make it work, and the consumption was not small...... However, this spiritual realm is also quite easy to use, not easy to break, according to my father, it is enough to repair it once in a hundred years. Tang Guo explained.

"I see?"

Lin Yu looked up at the seven pillars of the Heavenly Gods, and a sense of insignificance rose in his heart, like an ant, which made people powerless to resist.

"Alright...... Let's go......" Tang Guo took Lin Yu's hand and forcibly dragged him away, and then they went to the martial arts training ground, the armory hall, and the Yao Chi, which is famous all over the world and can be called a fairyland on earth, time passed unconsciously, and when night fell, Tang Guo sent Lin Yu back to the small courtyard where he lived, and then left with a few words.

Looking at Tang Guo's back, Lin Yu's heart was warm, this little girl's innocence and kindness left him with a great impression, in this inner door that respects the strong, she did not have any discrimination at all because of her low cultivation, but spared no effort to help herself, and answered all the questions carefully and in detail.

"It's really heartwarming. Lin Yu said softly, a heartstring was touched, and his heart of pity rose spontaneously, and he stood dumbfounded, until Tang Guo's back completely disappeared from sight Lin Yu came back to his senses, sighed softly and returned to the secluded courtyard, now his biggest problem is the progress of his cultivation, to break through the Xuan Rank within a month, so that he will not be swept away by the old man of Lei Hu.

Sitting on the big stone in the center of the courtyard again, running the Seven Star Sword Technique, Lin Yu's heart soon had completely settled down, and the power of the gathered stars shrouded his body, Lin Yu's figure looked a little hazy when he was shrouded, and his expression became extremely solemn, allowing the spiritual power to flow through the eight veins of the Qi Sutra, sensing the subtle changes carefully.

The spiritual power that grew step by step was surging, and Lin Yu was happy in his eyes, and he knew that his strength was increasing step by step.

Sitting cross-legged like this for three hours, Lin Yu spit out the turbidity in his body, slowly opened his eyes, and took out all kinds of pills he brought during the day, he was no stranger to the Gathering Spirit Pill, when he was in the outer gate, he robbed Wang Meng's Gathering Spirit Pill, which could easily break through to the Yellow Rank Sixfold, and the other two pills Washing the Pulp Pill, as the name suggests, can help the cultivator wash the essence and temper the flesh, and for Lin Yu today, the significance of swallowing the Essence Washing Pill is not very great.

Because he has reshaped his physical body when he was in the outer gate, his physical fitness is even much stronger than that of a cultivator of the Xuan Rank, and the effect of the Pure Heart Pill Lin Yu has also done some understanding, the Pure Heart Pill can allow people to get rid of distracting thoughts in a very short time, so that they can better understand that the power of heaven and earth has an extremely important effect on the future path to enlightenment, so among the three pills, the most precious may be the Pure Heart Pill, but to be honest, Lin Yu does not need the Pure Heart Pill, because he has a seven-star sword technique, and he does not need to rely on external forces to settle himself down......

"Only the Gathering Spirit Pill is useful!" Lin Yu muttered to himself, carefully put away the Purifying Pill and the Pure Heart Pill, picked up a Gathering Spirit Pill and swallowed it, it still tasted the same as before, a little bitter, but at this moment, Lin Yu's mind was smooth, and after the Gathering Spirit Pill melted, it turned into thousands of strands of pure spiritual energy and melted into the blood.

Lin Yu carefully guided, trying not to let any spiritual energy escape and cause waste, all said slow work, sure enough, Lin Yu completely digested a spirit pill actually consumed three hours, but Lin Yu's harvest was also very obvious, the spiritual power in his body became more powerful, although it was not too obvious.

"The second one. Lin Yu said, he had already bitten the second Gathering Spirit Pill, it was still a long and cumbersome fusion process, but Lin Yu would not feel impatient at all, the sky had slowly brightened, Lin Yu had been sitting all night, but he did not see the slightest tiredness, but looked radiant, this night his harvest was great, because after swallowing two Gathering Spirit Pills, his cultivation had reached the middle level of the Yellow Rank Sevenfold.

He didn't continue to swallow the Gathering Spirit Pill, firstly, because there was no starlight now, and the Seven Star Sword Technique could not exert its maximum effect, and secondly, it was because Lin Yu needed a period of time to let his body adapt to this sudden increase in strength, and to fight steadily, so as not to lay the seeds for his future path of cultivation!

Still sitting dry, letting the spiritual power flow, Lin Yu does not guide or block, there is a tendency to indulge, and it is three hours, after Lin Yu's body completely adapts to the current strength, his stomach is already a little hungry, go to the outside canteen to eat, he first came to Xingchen Peak, and there is no one else he knows except Tang Guo, Tang Guo did not appear today, it seems that he is busy with his own cultivation, Lin Yu has no other place to go, so he simply returned to his residence.

Lin Yu did not continue to cultivate, but took out the "Introduction to the Five Elements and Basic Theory" that he had just borrowed yesterday and studied it carefully, Lin Yu felt that the things that could be collected into the Xuantian Sect Library Pavilion must not be bad, he guessed well, although the "Introduction to the Five Elements and Basic Theory" was placed on the first layer, that is, the lowest layer, but the various knowledge contained in it still benefited Lin Yu a lot.

He mainly studied the attributes of the two elements of thunder and water, and there was no doubt that the thunder cultivator was undoubtedly the highest in terms of combat power under the same rank, and the use of elemental power was roughly divided into three stages, the first stage could be called borrowing, the second was control, and the third was domination......

The first stage of borrowing is the most elementary stage, which is to rely on the innate affinity for the elemental attributes, or use the elements of heaven and earth to merge on the weapon or a certain part of the body to achieve the strengthening effect, and whether the strengthening effect is strong or not depends on the individual's talent for that system, his own cultivation, and the extent to which he has perceived.

The control of the second stage is no longer comparable to the first stage, and the cultivators at this stage can completely concentrate on gathering the elements between heaven and earth to kill the enemy without relying on any medium!

The third stage of domination is very vague in the book, saying that very few people have reached such a state in the past thousand years!

Lin Yu thought carefully about the battle between Xiao Yang and Chu Xiangyue, they must have only been in the first stage, and he didn't know how many people in this Xuantian Sect had already reached the second stage, if he had the chance, he really wanted to see it.

Retracting his thoughts, Lin Yu continued to look down, compared with the battles accumulated in his previous life, Lin Yu often had a flash of inspiration, and his understanding of the power of the elements became more and more profound, and in the blink of an eye, it was already night, when the power of the stars was at its strongest, Lin Yu would definitely cultivate the Seven Star Sword Technique, and continue to swallow the remaining three Gathering Spirit Pills.

Cultivating and fusing the Gathering Spirit Pill at night, and reading books during the day, except for eating, Lin Yu rarely walked around outside, and his monotonous life soon passed for three days......

In the early morning of the third day, Lin Yu opened his eyes, that is, he had swallowed the last Gathering Spirit Pill last night, and his cultivation had reached the peak of the Yellow Rank Sevenfold, and he stretched his hands and feet, feeling unprecedentedly good......
