Liu Junhuai, who was meditating hard, finally let go of his thoughts, what should come will come after all, and the top priority is to quickly improve his strength. Originally, rebirth happened to him like a dream, and it is natural to have a few more incredible, Liu Junhuai smiled bitterly when he thought of this.

Liu Junhuai put away the "two-color blood tonic grass" and took out the golden essence stone. The golden essence stone must be absorbed in an expanded state, fortunately, the temperature in the cave and the valley is not much different, the golden essence stone will expand on its own once it is excavated, and the piece of golden essence stone in his hand is almost exhausted as soon as the "Nine Changing Hearts Method" exercises are running, and the true yuan power in his body has reached the extreme immediately. He felt the sound of several meridians in his body 'boom', and the whole person suddenly became lighter, and at the same time, he felt the endless new true yuan power surging from the dantian, and everything became extremely clear.

"Seventh Order Qi Training! The Golden Essence Stone is worthy of a god-level heavenly and earthly treasure, and its energy is really powerful. Liu Junhuai shouted excitedly.

Finally, in the late stage of advanced qi training, Liu Junhuai opened the Heavenly Eye, and immediately felt that the power of exploration and divine sense had expanded to a radius of thirty miles, and there were signs of fusion between the power of exploration and divine sense. He knew that the combination of the two would be more concealed, and the functions would be fuller, and what was even more rare was that the Heavenly Consciousness had attack power, and the attack launched under the condition of sufficient true Yuan power of the sea could be concealed and sharp, and it could have an unexpected effect.

Of course, advancing to the late stage of Qi refining, the strength, capacity, and quality were several times stronger than those in the middle stage of Qi refining, and he knew that this unintentional realm improvement mainly relied on heaven and earth spiritual objects, and he still needed to continue to collect and accumulate in order to cultivate to the Great Dao to the sky. Obtaining heaven and earth spiritual objects not only requires chance, but also requires all kinds of financial, material and human resources, and with sufficient strength to collect the necessary heaven and earth spiritual objects, Liu Junhuai's desire to improve his strength is even stronger.

After picking up another piece of golden essence stone and absorbing it, Liu Junhuai could feel the further expansion of the meridians and the capacity of the dantian more than doubled.

The Heavenly Divine Eye is still running, the golden threads are constantly generated, the golden balls are more solid, and the Heavenly Sense is becoming clearer and more free.

Out of the cave, Liu Junhuai continued to descend the stone steps, and returned to the cave before the true yuan power was exhausted, and the time he held on this time was twice as long as the previous one. After repeated training and recovery, the realm has improved slightly, and the time for training has come. These few times the cultivation in the cave did not use the golden essence stone, simply absorbing the aura can lay a more solid foundation, the golden essence stone is good to use when breaking through the bottleneck, only a solid foundation will have strong strength.

Teleported out by the formation, Liu Junhuai planned to take a turn on the second and third floors of the Vientiane Building, after all, he had not understood these two floors since refining the Vientiane Building.

On the third floor, Liu Junhuai couldn't cry or laugh. Of the five rooms on the third floor, only the refining room and the formation room can be entered, and the other three rooms all show that they have not reached the permission to use them. He didn't plan to go into the formation room, after all, he still didn't know anything about the formation. And the body refining room that can be entered is not necessary to enter for the time being because Liu Junhuai has cultivated the body quenching technique, after all, his own realm has improved, and he can make faster progress in cultivating the body quenching technique.

The library on the second floor made Liu Junhuai linger. The amount of knowledge here is too large, and there are all kinds of things involved, and he has been immersed in the sea of books for nearly two days.

In the past two days, Liu Junhuai digested more of the characteristics and functions of heaven and earth spiritual objects, practiced the basic introduction of pill refining, and had a further understanding of the geographical location and distribution of forces, and developed a strong interest in medical skills.

It's just that the amount of information about unknown new things required is too huge, and Liu Junhuai had to grit his teeth to stifle the greed in his heart, but he was full of confidence and courage in his future development direction.

The only thing that disappointed Liu Junhuai was the lack of relative cultivation techniques and mental tips in the library pavilion.

But after speculating for a few breaths, he was much calmer in his heart. After all, the "Nine Changing Mind Method" and "Tianyantong" that I got were all against the sky, and even the "Escape Knife Technique" I got in the waterhole was also a Xuan-level technique. With the first two exercises, his horizons have also broadened a lot, not to mention that he has a more rebellious existence like Vientiane Building, Liu Junhuai even feels that there are no exercises and tips in Vientiane Building, or it is too precious to appear in the Library Pavilion, probably there will be a five-story treasure room, but unfortunately the realm can only enter when it reaches the Jindan period.

Thinking that it has been half a year since he came out of the cave in the Heguanling Mountain Range, Uncle Huan must not have entertained himself, and it is time to go back. It's just that Liu Junhuai is still thinking about the "Fire Eclipse Lotus" and "Heavenly Lotus Heart Fire" in the magma pool, although he has a magic weapon array in his hand, but his ignorance of the formation made him decide to go to the three-layer formation room to practice.

Come to the third floor and enter the formation room.

There were also more than a dozen jade plaques hanging on the walls of the formation room, and unlike the training room, only the first one had broken the seal. Heavenly Sense Penetration, it turned out to be the basic principle and derivative formation diagram of the Mixed Yuan Array.

In the library pavilion, Liu Junhuai learned some formations generalization, and the formation has nine base arrays, namely: mixed yuan array, yin and yang array, three-talent array, four-elephant array, five-element array, ** array, seven-star array, gossip array, and nine-palace array. All formations are evolved from the combination of these nine base arrays, and the mixed yuan array, yin and yang array, and three-talent array are the foundation of the foundation, containing the evolution of the Great Dao, and the truth of heaven and earth.

The simplest and most direct way to use the formation is to gather the aura of heaven and earth and use it in a certain area, so as to achieve the effects of attack, defense, sealing, and so on. And to gather the aura of heaven and earth, it is necessary to use the Mixed Yuan Array, to be precise, to use the Gathering Spirit Array that has been comprehended from the Mixed Yuan Array.

This jade plate is the construction principle of the derivative array diagram spirit gathering array and fire yuan array.

According to the cultivation of the formation mage, the spirit gathering array sets the corresponding level of advanced formations according to the grade of the spirit stone or spar, and the rune technique used to arrange the formation is not very cumbersome, but in this way, it took Liu Junhuai a few hours to become familiar with it.

Six pieces of lower grade spirit stones were thrown down according to the direction, and his fingers drew a few runes out of thin air with a few spells, a burst of white light flashed, and a primary spirit gathering array appeared in front of Liu Junhuai, and Liu Junhuai in the array immediately felt that the surrounding spiritual energy was slowly gathering in the array.

After trying out the medium-grade spirit stone and the high-grade spirit stone respectively, Liu Junhuai was very happy, and he was also a formation mage.

The Fire Yuan Array is similar to the Spirit Gathering Array, the difference is that it needs a Fire Spirit Stone to make the array eye, Liu Junhuai has a lot of Golden Essence Stone in his hand, but the effect after the trial is unexpectedly good.

Liu Junhuai, who was still immersed in the perception of being a first-time array mage, suddenly felt a jade plaque hanging on the wall trembling, and reached out to take it down and probe into the heavenly sense.

The jade plaque shows that with the cultivation of the array mage, the formation can be refined into a permanent array disk, which can be used by embedding the activation source. Formation mages are divided into nine levels, after which they can be promoted to formation masters. The formation master is level 3 and can be promoted to the formation grandmaster. The cultivation supreme formation master can refine the formation into a formation that does not need to start the source, and the formation symbol is a disposable item, and the power varies with the cultivation of the formation mage.

There are a total of fifteen jade plaques in the formation room, each of which represents the first level, and the next level of jade plaque will be automatically opened after each jade plaque is fully comprehended.

At the end of the jade plaque, there is a second-level formation diagram and a rune technique.
