After letting go of the divine sword and letting the sword spirit refine the dark and yellow Qi, Wang Chen's energy also focused on cultivation.

This time, Wang Chen got three pieces of spiritual materials, one of which was an ice attribute immortal tool. After refining this immortal tool, Jiezhu got more than 300 kinds of ice attribute mystery, but many.

The second is a lotus seed, which is said to be the lotus seed of the five element lotus. In fact, the lotus seed is true or false, even the disciple doesn't know. This lotus seed was only obtained by chance. There are too many descendants of such congenital immortals in the fairy world, but nine times out of ten they are fake.

However, Wang Chen felt extremely sharp, especially in the boundary beads. He vaguely felt the power of the five elements contained in the lotus seed, which was still a little familiar.

Innate five element Qi!

Wang Chen is looking forward to this. After all, the innate five element lotus is said to be one of the most suitable treasures for refining the five element magic power. If you can refine the immortal tool and breed it for a long time, it will greatly increase the power of the magic power, which is not comparable to ordinary treasures.

Wang Chen is very interested in this kind of treasure.

The third thing is soil.

The essence of the earth is the treasure of many properties of the earth and the properties of the earth.

Of course, another function of Xi soil is to cultivate spiritual materials. Of course, in general, few people do so. Xi soil is so precious. How can ordinary spiritual materials be willing to use this treasure.

Wang Chen is willing.

After getting a handful of Xi soil, Wang Chen felt the strong smell of soil attribute above, which was full of vitality. It was undoubtedly Xi soil.

"It would be nice if I could stay in the earth for nine days. This is really a rare spiritual material in the fairy world. If I can get it, I don't have to worry about my future cultivation."

Wang Chen thought in his heart that he took this piece of soil to Qingling sacred wood. Soon, on the soil, a dynamic earth attribute force entered the root of Qingling sacred wood, and then Qingling sacred wood grew up rapidly at a visible speed. The trees that were already one foot high kept soaring.

Hoo Hoo!

In a moment, the Qingling sacred tree rose to more than three feet high, and the branches radiated more than ten feet away. It looked lush. Even the breath emitted from the Qingling sacred tree made Wang Chen feel the situation of the spirit, as if he felt the change of the world in an instant.

The mystery and space barrier between heaven and earth become more clear, the soul moves, and the speed of understanding the mystery is greatly increased.

"Well, it is worthy of being a pure spirit divine wood. In this way, the speed of my understanding of metaphysics will increase, and the remaining metaphysics will be completed in a shorter time."

Wang Chen was overjoyed. At the same time, eight spirits used the power of measuring the sky and breaking the ruler to understand the mystery in the world beads. The remaining spirits controlled the body to continuously refine the spirit and improve cultivation.

Wang Chen has now understood more than 800 kinds of mysteries, and this number is appalling.

Ordinary celestial beings are more than 200 kinds, close to 300. After reaching 300 kinds of metaphysics, they can cast the fairyland. Unless they are monks with excellent talent and great confidence in themselves, they will continue to understand the metaphysics until 400, 500, 600, or even 900.

999 kinds of mysteries have reached the limit, and even casting the immortal base with the supreme magic is enough.

In fact, as long as there are 900 kinds of supernatural powers, the immortal base can be cast. This kind of immortal base is at least seven grade immortal base. If its own skill and talent are appropriate, it is likely to be eight grade immortal base or even nine grade immortal base.

However, in the fairy world, such a large fairy domain, a monk of nine grade fairy base only came out in a million years. It can be seen that the monk has understood the difficulty of metaphysics.

However, the higher the cultivation, the stronger the spirit, and the less it is to understand the mystery. Moreover, the higher the grade of Xianji, the less difficult it will be to understand the mystery.

Wang Chen didn't know the difference of Xianji before, but after entering the five element Xianzong, he saw and heard more, and he understood how terrible it was that Tang Shiyue said he was the Xianji at the top of the eight grades that day.

However, although he is a eight grade immortal base, he doesn't understand much. This is another way to obtain the immortal base.

One way to obtain the immortal base is to take the divine power as the immortal base and blend it to create it. The other way is to use the power of blood to produce the immortal base. The other way is to understand the immortal base that has not been existed before.

In the Tianyuan world, high invincible and beast worshippers take the road of understanding Xianji by themselves. Those who can understand Xianji by themselves are people with extraordinary savvy and extraordinary talent. Xianji is not low, mostly above the seven grades, and even many of the nine grades. That's why Wang Chen made up his mind to understand Xianji by himself.

…………

After using Xi soil, Qingling sacred wood grew up rapidly, and the efficacy of Qingling sacred wood was greatly improved. Qingling sacred wood, which had little effect, played its role again.

In an instant, after Wang Chen had broken the ruler, his speed of understanding the mystery increased by 20%.

Twenty percent, it's a great change.

The mystery of the five elements in the world bead has been almost understood by Wang Chen. Therefore, Wang Chen no longer understands the mystery of the five elements, but focuses on the avenue of Yin-Yang mystery.

Yin Yang Avenue, that is, the mystery of yin and Yang, is the most difficult to understand. It is more difficult than ordinary mystery, and the speed of understanding is also slow. If Wang Chen didn't have a broken ruler, the boundary bead and the pure spirit divine wood, it would probably take thousands of years to understand a little.

However, now the understanding of Yin-Yang mystery is going on rapidly and steadily, but the speed is slowly slowing down.

The combination of yin and Yang metaphysics is roughly equivalent to more than 400 kinds of ordinary metaphysics, but it took Wang Chen nearly 700 years to understand more than 400 kinds of metaphysics. In the first 400 years, he understood 300 kinds of metaphysics, and in the remaining 300 years, he only understood 100 kinds of metaphysics, which can be seen that the speed of understanding metaphysics has slowed down.

After understanding the mystery of yin and Yang, Wang Chen felt the changes between heaven and earth.

The world originally divided into five elements and wind, thunder and ice attributes has changed again in Wang Chen's eyes. Both five elements and wind, thunder and ice can be divided into yin and Yang attributes.

"The avenue of yin and Yang is really extraordinary."

The more immersed in the yin-yang Avenue, the more Wang Chen can find the mysterious power of yin-yang, and after discovering that the yin-yang Avenue is different from other avenues, Wang Chen has a certain idea.

"In fact, this fairy base is like this yin-yang Avenue. It wants to integrate all kinds of metaphysics. It looks like an avenue to form a powerful force, which is different from other metaphysics."

Wang Chen has seen many Xianji. Naturally, he also has a lot of knowledge about Xianji.

Supernatural power is to combine the metaphysics together, combine them in different ways and different metaphysics, and then give play to a powerful power. This power is incomparably powerful with the help of the metaphysical power. However, Xianji is not. It seems that Xianji has transcended the heaven and earth, integrated the mystery understood in the heaven and earth again, and become an existence between the heaven and earth and outside the heaven and earth.

Wang Chen had these guesses, but he thought it was right.

"For example, the fire earth mystery melts into the lava fairy base. The lava mystery itself does not exist in the world, but the lava itself exists. Therefore, the basic body of the lava fairy is like pretending to be the main road in the world."

"Cultivating immortals is a journey against the sky."

Wang Chen has a little understanding of this. Since he has this understanding, Wang Chen has strengthened his confidence. Since he wants to cast a fairy base, he needs to cast a different fairy base. A unique fairy base is the most suitable fairy base for himself. For this, Wang Chen has some plans.

In addition, Wang Chen continued to understand the mystery of wind, thunder and ice. The three mysteries were originally the mystery of ice attribute, which was the least swallowed by the beads in Wang Chen's world. Who knows that after the bred ice attribute fairy ware was refined, the mystery of ice attribute was the most.

These three kinds of metaphysics attack 300 kinds, of which 200 kinds are ice attribute metaphysics. It took Wang Chen 400 years to understand these metaphysics.

So far, with the avenue of yin and Yang, Wang Chen understood more than 1500 kinds of metaphysics, nearly 1600 kinds. This number is terrible, especially with Wang Chen's cultivation of immortals.

Even around Wang Chen's body, as long as the skill is operated, there will be various lights flashing, showing the mystery that Wang Chen understands.
