One stick of incense, two pillars of incense, half an hour, one hour。。。。。。 Finally, after two years and seven months of arduous struggle, Lu Yi's spiritual power broke through to the fourth order, and now Lu Yi can compete with the spiritual coercion of the quiet room on the fourth floor for three hours.

And Lu Yi's cultivation has also reached the peak of the early stage of the third order, and it is not far from breaking through to the middle stage. Out of the Shujue Building, Lu Yi came to Fang City and released his spiritual power, and in an instant, the situation in Fang City within 500 zhang appeared clearly in Lu Yi's mind.

You must know that when he was at the third level of spiritual power, Lu Yi could only feel the range of fifty zhang at most, but now it has increased tenfold.

Whether it is cultivation, formation, or spiritual power, the first, second, and third orders are called the primary stage, the fourth and fifth orders are the intermediate stage, the sixth and seventh orders are the advanced stages, and the eighth and higher levels are a brand new stage.

Reaching the fourth level of spiritual power means that Lu Yi has crossed a hurdle in spiritual power, providing strong support for the advancement of the cultivation formation.

Moreover, after the spiritual power reaches the fourth order, you can use the spiritual power attack, this kind of attack that hurts people invisibly is a fatal blow to the low-level monks.

Of course, a specific method is required to use a mental power attack, and there are many restrictions, and it also consumes mental power, if the other party's mental power is higher than yours, it will also bring you a strong backlash, and there is a key problem, that is, the scarcity of mental power attack techniques, there are few methods in the outside world, therefore, few people will use it, even if they can use it, they are generally not too sure, and they will not be able to cast it easily, Lu Yi still found this kind of magic in a pile of dusty jade slips on the fourth floor of the magic building, and learned a method called

"Divine Thorn" psychic attack spell. With Lu Yi's current formation cultivation and spiritual power cultivation, as long as Lu Yi's "Weilan Fingering" is the second major achievement, he will be able to depict and control the ordinary fourth-level formation and impact the fourth-level formation mage.

When the fourth-level formation mage arranges the formation, he does not need to be limited to carving the formation talisman with rune materials, but can use any object containing energy as the formation talisman, and even if some formations are engraved on items with no energy, the formation can also be activated by using spirit stones as formation eyes.

And when the formation reaches the fourth order, the formation can be engraved on the refining magic weapon, and the magic weapon engraved with the formation can be accompanied by special effects, making the magic weapon more powerful, because any magic weapon, no matter how high the level, as long as there is no engraved magic circle on it, it cannot be regarded as a perfect magic weapon, and the use effect is monotonous and the power will not be too strong.

The spiritual power has reached the fourth level, and the communication with the little turtle has instantly gone up to a higher level, and now, Lu Yi and the little turtle can clearly understand what the other party thinks, which makes the cooperation between the two more tacit, which is what Lu Yi yearns for the most.

The back mountain of Yaoshan is vast, inaccessible, there are many monsters, all kinds of flowers and trees are rich in minerals, and it is a natural warehouse of Yaoshan faction.

It is said that in the early years of the sect, an eighth-order monk had explored for thirteen years and arrived at a boundless swamp, where he encountered a shape-shifting eighth-order demon beast on the edge of the swamp, and according to this demon beast, the other end of the swamp stretched all the way to the Chaos Sea.

This powerful man reached an agreement with the shape-shifting demon beast, neither side was allowed to enter the hinterland of the other party's eighth-order or higher monk demon beasts, nor was it allowed to attack the other's cultivator demon beasts whose cultivation was lower than the eighth order, and the part behind the Yao Mountain was used as a training place for the low-level existence of both sides, and their cultivation was improved through mutual fighting.

For this reason, it has also become the best place for the disciples of the Yaoshan Sect to experience and explore, and many monks of the sixth and seventh orders have chosen to break through in the back mountain, leaving behind many caves, and it has also become a place for latecomers to find treasures.

Almost all the disciples of Yaoshan have the experience of exploring in the back mountains, and every ten years, the sect will also organize a back mountain exploration competition, setting goals of different difficulty for monks of different levels, and those who achieve the goals will have a lot of rewards.

After the breakthrough of spiritual power, Lu Yi planned to go out again to experience it, and by the way, break through the lower cultivation. Lu Yi took a one-year leave with Yulinzi, saying that he would go to the back mountain to test what he had learned in recent years, and Yulinzi told Lu Yi about the situation in the back mountain, and told him not to go too deep before agreeing to Lu Yi to go.

Niuniu has also grown up a lot now, and there are more than a dozen little demon beasts in captivity, and when she heard that Lu Yi was going to the back mountain, she shouted to go together, which made Lu Yi's head big, and finally she was able to get out after promising to find at least three or more fun demon beasts for Niuniu.

Lu Yi spent 5,000 sect contributions to buy a third-order flying mount rain goose in the Spirit Pet Hall, the rain goose is an adult third-order demon beast, with a wingspan of about four meters, which can be ridden by three adults at the same time, with a fast flight speed, docile temperament, easy to domesticate, the only drawback is that it does not have any combat ability, it can only be used as a mount, it is very popular among low-level monks, but the price is relatively expensive, so it is also a kind of chicken-like existence.

Lu Yi didn't expect to use it to fight anyway, but it was very much in line with Lu Yi's current needs. After two days of continuous flights, Lu Yi finally arrived at the area infested by third- and fourth-order demon beasts in the back mountain.

After landing, the rain goose was put into the spirit pet bag, Lu Yi released the little turtle and began to look around the surrounding environment.

The back hill is a descending slope, gradually and slowly lowering the height from the top of the hill to a swamp. The vegetation also changes from tall and dense to low and sparse.

The area where Lu Yi is now located, halfway up the mountain, is a red pine forest. The red pine is a second-order material, hard and abnormal, it takes hundreds of years of history to become a tree, the red pine trees in this pine forest are tall, four or five zhang short, dozens of zhang high, the needle-like pine leaves are like thorns, and they will bring a certain itch when they penetrate the skin, and there are a lot of pine cones hanging on the trees.

There are a large number of low-level demon beasts living in the red pine forest, which is the place where third-order and fourth-order demon beasts such as mountain bears and blue tigers dominate, and there are also some poultry demon beasts that also inhabit the trees.

Lu Yi let go of his spiritual power and felt the situation within five hundred zhang, but he didn't find any powerful demon beasts, only a mountain bear was lazily tickling on the red pine tree.

Lu Yi had no interest in it, discerned the direction, and strode towards the depths of the back mountain.

Every once in a while, Lu Yi would let go of his mental power to perceive, and continued to move forward without finding the target, paying attention to flowers and plants along the way to see if he could encounter some rare materials and pick them by the way.

After walking and stopping all the way for a long time, I finally found my first target today, a blue tiger.
