Lan Xin's suggestion made Lian Xiang a little moved, "If you upgrade the 'Book of Natality' to cooperate with Lan Xin's saint-level martial arts, then the income will be calculated in the tens of millions." ”

After thinking about it, he decided to give it a try and get another high-level martial art to cooperate with Blue Heart.

Now there are a lot of martial arts that can be upgraded in Lian Xiang's hands, among which most of them are heaven-level martial arts, and there are only two saint-level martial arts, one is the saint-level low-level martial art "Sword Qi Vertical", and the other is the saint-level mid-level martial art "Sword of the King".

Theoretically, upgrading "Sword of Kings" to the high-level saint-level is the most valuable! However, Lian Xiang has many concerns, "The Sword of the King" is a middle-level martial art of the holy level, and upgrading to the high-level of the saint-level is too high, he is afraid that his innate true qi is insufficient! And if he really upgrades to a unique high-level saint-level martial art, he is still a little reluctant to sell it.

But the heaven-level martial arts are still a little unsightly now, and it's not worth the effort to upgrade them once!

Having made up his mind, Lian Xiang began to prepare his martial arts upgrade plan.

However, this time, Lian Xiang did not choose the method of going to the immortal space to fight to replenish the innate true qi.

Lian wanted to use light energy and heat energy to replenish the innate true qi to provide energy to the Book of Natal Beings, but after trying it, he found that although this method was feasible, the innate true qi consumed by the Book of Natal Energy when upgrading the content in it was too large to meet it in a normal way.

In the end, Lian decided to try the hedrons.

Because there is a pitiful lack of aura on the earth, congenital-level martial artists on the earth who want to quickly improve their cultivation will generally choose a spar to assist in their cultivation, refining the spar to absorb and store the aura in the spar, so as to improve their cultivation.

Lian thought that it was because he had too many ways to cultivate, so he didn't rely on the spars, so he had never been in contact with the spars.

However, the main reason is also because he has no money, so he does not use spars. Now Lian Xiang has money, and he still uses it to make money, so he wants to see if the spar can meet his requirements more quickly.

Although there are no spars produced on the earth, spars are a necessity for the cultivation of martial artists on the earth, and they are also the main energy source for people's lives, so there are spars sold in every city.

Lan Xin gave Lian Xiang two million before, and Lian Xiang bought all of them with spars.

100 Earth Coins may be exchanged for one Crystal. Crystals are made of hedrons, and 100 crystals can buy a finished crystal. Lian Xiang's 2 million Earth Coins can buy exactly 200 finished crystals.

200 pieces of finished spars, exactly two boxes. Lien wanted to use his flying car to transport them home, but the boxes were relatively large, and Lien wanted to use the flying car twice to transport them home.

Lian Xiang moved the two boxes of spars to the underground practice room, and looking at the wooden box more than one meter long, Lian Xiang sighed: "When there is a legendary storage spirit weapon, it will be trouble-free, and there is no need to move it around so hard." ”

Lian Xiang opened the wooden box, took out a processed cube spar from it, and studied it carefully.

Lian Xiang is still a close observation of the spar, boxy, crystal clear, like crystal, very heavy in the hand.

"Such a hedron can provide power for a flying car for more than ten years! It's incredible! Where is this thing made?"

Hedron is not a necessity for the cultivation of martial artists, and it is also the main energy source nowadays. It is pollution-free and energy-free, which cannot be compared to old energy sources such as nuclear, oil, and coal.

Lian Xiang took the spar in his hand and operated the "Refining and Refining Qi Vein" and "Spirit Fetus Breath Vein" in his body. Suddenly, the spar in Lian Xiang's hand changed, and a trace of energy gas emanated from the content of the spar surface, which entered his meridians through Lian Xiang's palm, and was converted into innate true qi through his meridians, and finally stored in the dantian qi sea.

The gas emitted by the spar is only a faint filament, but the innate true qi transformed is very large, even if the innate true qi of Lian Xiang is denser than the innate true qi of ordinary martial artists, it still transforms a lot of innate true qi.

"Good thing, this spar is really a good thing!" Lian wanted to speed up the absorption of the spar in his opponent.

One minute......

Five minutes......

Ten minutes......

After about ten minutes, the innate true qi in Lian Xiang's body reached a saturated state. Lian Xiang tried to impact the Innate Sixth Order, but he didn't succeed.

"It is said that the innate fifth order and the sixth order are a watershed, it seems that it is not enough to impact the innate sixth order light to have enough true qi, and it still needs to fight. ”

Lian Xiang is a combat-type cultivator, he can go all the way in battle, and no cultivation barrier can make it difficult for him.

Lian Xiang was not in a hurry to advance, his first task today was to upgrade his martial arts.

Lian Xiang observed the spar in his hand, and made the spar much lighter, and the weight was about one-third less.

"I didn't expect that the energy contained in a spar is so large, enough for me to use it twice!" "Lian thought about calculating that if all his true qi was exhausted, one spar would be enough to replenish his innate true qi twice.

Lian Xiang stopped absorbing the spar, and then woke up the sleeping Book of Natal in his mind.

"If the Book of Natal can directly absorb the energy in the hedron, then I won't have to bother. But it's okay to think of this process as a kind of cultivation. ”

Lian wanted to use his consciousness to open the "Book of Natal Life" in his mind, and was about to control the page of martial arts of "Sword Qi Verticality", when suddenly, the "Book of Natal Life" suddenly shook, and without any signs, it began to actinize, turning from a substantial book into a ball of multicolored light.

The five-colored light rushed out of Lian Xiang's sea of consciousness from Lian Xiang, and directly entered Lian Xiang's meridians, white, red, green, blue, and gold five different colors of colored light traveled in Lian Xiang's meridians, and then turned around in Lian Xiang's five internal organs and six mansions, annihilating the toxins and impurities in his meridians and five internal organs and six mansions, and finally penetrated through his body and rushed out of Lian Xiang's body.

Red, white, blue, green, and gold flashed out of Lian Xiang's body and swirled around his body.

Lian Xiang found that these five colored lights seemed to have some kind of connection with him, and as soon as Lian Xiang's mind moved, the five colored lights collided together in Lian Xiang's chest, and the colored light began to materialize, and the colored light slowly restored to the appearance of a book.

A moment later, the Book of Natal Destiny, which really existed in Lian Xiang's mind, appeared in front of his eyes, becoming a book that he could see and touch.

Lian Xiang seemed to have comprehended something, his mind moved again, and the "Book of Natality" in front of him began to photonicize again, turning into five colors, and then the five colors were sucked into his body, and finally gathered in his mind, restoring to the appearance of the "Book of Natality".

Then Lian Xiang tried again, and the "Book of Natal Destiny" turned into five colored lights again, rushing out of his body, and finally turned into a book that floated in front of his eyes.
