Wan Zhao not only gave the secret technique of "Taigu Jue" to Yan Yu, but also drove the hearse to take the second daughter to the Demon Sea region. He was tired all the way, and he never saw the rain take out a spirit stone! The spirit stones consumed by the hearse on the road were all from his pocket......

Still controlling the hearse to drive quickly, Li Yu behind Wan Zhao suddenly slowly stood up.

Seeing this scene, Wan Zhao's eyes lit up, and he quickly turned around and looked at Yan Yu with expectant eyes.

"Wan Daoyou, I have roughly mastered the "Taigu Formula", and now I need to experience it myself. Seeing Wan Zhao turn around, Yan Yu said without a look.

Hearing Yan Yu say this, Wan Zhao was slightly stunned, and secretly thought to himself, "This "Taigu Technique" is extremely mysterious, after the old man got it, it took more than ten years to be able to use it freely, I didn't expect this red-clothed female cultivator to master this method so quickly......"

After nodding to the rain, Wan Zhao pressed on the spirit plate with one hand, controlling the hearse to stop.

In a moment, the hearse slowly stopped, floating in the middle of the desert.

Flying down, Yu Yu stood in mid-air, the yellow sand around her swept by, blowing her red dress.

"Wan Daoyou, borrow your token......" Yu Yu looked back at Wan Zhao and said with a smile.

Hearing this, Wan Zhao was slightly embarrassed, and hurriedly took out a pure black token from the storage bag, threw it with one hand, and threw it to Li Yu.

Taking the token and feeling the power of thunder and lightning on it, Yu Yu nodded secretly.

Flying forward for some distance, Yu Yu stood in mid-air, holding the token in his hand, and activated the "Taigu Jue".

In an instant, the power of thunder and lightning appeared around her, and the crackling was very harsh.

There was a "stab" sound, accompanied by a dazzling light of thunder and lightning, and the rain disappeared.

Seeing this scene, Wan Zhao narrowed his eyes, and muttered in his heart, "This woman's comprehension is really good, and she has learned the "Taigu Technique" in a short period of time......

As for Wu Jing'er on the hearse, she was devoting herself to cultivating the magic tricks, completely shielding her senses from the things around her.

As soon as the lightning flashed, the rain appeared in a desert with no people, and the yellow sand was everywhere, and the scenery could not be seen clearly.

"Huh...... This secret technique is indeed true. Muttering to himself excitedly, Yu Yu carefully looked at the black token in his hand.

Now that I feel it again, the power of thunder and lightning in this token is still majestic, but compared to just now, it has passed a lot.

Looking at himself internally, the spiritual power in his body has barely passed, and the power of cultivation is still strong.

"It seems that this "Ancient Technique" is mainly to consume the power of thunder and lightning to perform, and there is not much demand for spiritual power and cultivation......" After muttering to himself for a while, Yu Yu unfolded his divine sense and enveloped himself.

Turning around, the "Forbidden Eye" instantly moved, carefully examining the black token in his hand, and feeling the power of thunder and lightning on it.

After watching it for a while, the rain once again started the "Taigu Trick".

In an instant, the electric light roared, and the electric wire reels were handed over to him. The rain slowed down, and the operation of the "Taigu Jue" also slowed down. Under the careful observation of the divine sense, a complex formation composed of electric wires appeared under his feet.

With a light "huh" in his mouth, Li Yu found that the complex formation that appeared under his body had no traces of forbidden arts, only the power of simple and manic thunder and lightning.

The lightning was bright, and the figure of the rain disappeared with the electric light, and a scorching smell in mid-air was blown away by the strong wind that swept the yellow sand.

As soon as the lightning flickered, the rain returned to its original position. After taking a slight look at the black token in his hand, Yu Yu found that the power of thunder and lightning in it had lost nearly one percent.

After a moment of silence, Yu Yu flew into the hearse.

"How about it? Are you sure that you can improve this 'Ancient Technique' into a large teleportation array?" Wan Zhao asked eagerly when he saw the rain returning.

"Logically, it should be possible, but it will take some time. I'll need to walk through it to know the final result. With a hint of uncertainty, Yu Yu said slowly.

Seeing this, Wan Zhao was silent for a while, and then said with a smile, "It's okay, Daoist friends slowly come to their senses." However, with the old man's understanding of Taoist friends, he will definitely be able to ...... in the end."

Yu Yu answered with a smile, and then sat down cross-legged. Take out the jade slip given by Wan Zhao from the storage bag and examine it carefully.

In this jade slip, what is recorded is the arrangement of a large teleportation array, although it is a little complicated, and the materials required are also a little difficult to find, but it is enough for Yu Yu to learn from it.

After half a day, Yu Yu put down the jade slip in his hand, and his body slowly floated.

With a wave of one hand, a forbidden array that isolated the senses enveloped itself. Then, after closing his eyes, he fused this "Taigu Technique" with the arrangement of the large teleportation array, and slowly deduced it in his heart.

In the time that followed, Wan Zhao would often stop the hearse, let the rain get out of the car to perform some "ancient tricks", and then get in the car and continue driving. During this period, Wan Zhao gave Yu a black token with a complete power of thunder and lightning, which was convenient for Yu Yu to perform the "Ancient Trick".

Four years have passed in a flash. The "Spirit Crane" driven by Wan Zhao still hasn't walked out of this vast desert.

And the Demon Sea region is still far away, if you want to reach it, it will be difficult to do it without more than a hundred years.

On this day, Yu Yu opened his eyes again, sat in the air, secretly thinking about something, and said nothing.

And Wan Zhao was holding a jade slip at this time, sometimes looking ahead, sometimes looking at the jade slip, his expression was a little overbearing.

When he felt the rain stop and open his eyes, he sighed, turned around and said with a slightly sad face.

"Fellow Daoist, in a few days, we will completely enter the border land of the Northern Cold Immortal Domain and the Demon Sea Region.

At that time, we will no longer be able to drive hearses so aggressively. There are monsters and monsters everywhere, and there will inevitably be some dangers......"

Saying this, Wan Zhao saw that Yu Yu didn't have any reaction, and suddenly understood. Running the realm, with the power of cultivation, the voice said the previous words again.

Wan Zhao's voice mixed with the late stage realm of the god transformation easily penetrated the forbidden array arranged by Yan Yu, and the sound also entered Yan Yu's ears.

Hearing this, with a wave of one hand, the forbidden array surrounding him also dissipated.

Sitting cross-legged in the air, he turned to Wan Zhao, and Yan Yu said helplessly.

"Wan Daoyou, this improved version of the "Taigu Jue", the little woman can already arrange it. However, the materials required can be a bit more complex. ”

Hearing this, Wan Zhao's face was overjoyed, and he immediately spoke. "It's okay, the old man has a lot of spiritual materials here, and it should be enough for Daoist friends to arrange a large teleportation array. ”

Yu Yu chuckled, obviously thinking that Wan Zhao was too confident.

Laughing to himself, Yu Yu stood up, looked at Wan Zhao and said slowly, "The technique of arrangement, I have deduced it many times in my heart, and there is no longer any problem. But it requires three materials that are extremely difficult to find......"

"Fellow Daoists, please speak. Full of joy, Wan Zhao showed a serious expression on his face.

Seeing Wan Zhao's current demeanor, Yan Yu just smiled and said, "First, a powerful thunderbolt is needed as the source of the activation of the improved version of the 'Ancient Technique'. Second, I'm afraid that a lot of top-grade spirit stones are needed, and the preliminary estimate is at least more than twenty. Third, it is necessary to have an "empty dimensional crystal". ”

Yu Yu has been deducing for a long time, and if you want to arrange an improved version of the "Ancient Formula", this powerful thunder and lightning power and the best spirit stone are indispensable things. And this "empty dimensional crystal" is also the most important and indispensable thing.

This kind of spar is extremely rare, and it will not appear in ordinary stars. Only in the broken space can there be a chance to find it.

And this "Empty Dimensional Crystal" is also an indispensable thing in the arrangement of a large teleportation array. According to the jade slip that Yu Yu saw, this spar contains a stable spatial power, and it is useful for stabilizing space across large teleportation arrays over long distances.

Hearing the three things that came out of Yu Yu's mouth, Wan Zhao smiled heartily and said with some emotion.

"No problem, what Daoyou said, the old man is prepared. It seems that the old man's plan back then was still very correct......"

After saying this with joy on his face, Wan Zhao controlled the hearse and slowly stopped.

When the flying car stopped, Wan Zhao took out a large pile of things from the storage bag, wrapped them directly with spiritual power, and handed them to Yu Yu.

At this time, Yan Yu was also a little excited, she really didn't expect that Wan Zhao would have so many good things.

Placing these things in front of him, the rain began to look at it.

There are twenty top-grade spirit stones, three black broken trees full of thunder and lightning power, and one of the purple spars is the most eye-catching.

Manipulating these things floating in front of him, Yu Yuyu made a move, and they were all collected into his storage ring.

And the purple spar was grabbed by Yan Yu with his hand and looked at it carefully.

This hedron is somewhat elongated, about the size of an adult's palm. It is heavy in the hand, the weight is really not light, and the water chestnut angle is distinct, and it is very lubricating to the touch.

Yu Yu put this spar in the sun, and when he looked closely, there was a chaotic purple-black inside, and the sunlight could not penetrate it at all.

The divine consciousness melted into it to check, and suddenly there was a roar in my ears, and my heart was shocked.

"Wan Daoyou, the power in this "Empty Dimensional Crystal" is really strange, and the divine consciousness I used to check it has been wiped out by it......"

Wan Zhao put his hands behind his back, looked at Yan Yu with interest, and said with a smile, "Haha...... There is a chaotic space power in this spar, I'm afraid even the old monster of the infant transformation stage will not dare to touch it!"

"The power of space, is this what it feels like?" Looking at the "Empty Dimensional Crystal" in his hand, Yu Yu muttered to himself in his heart.

After looking at the spar in his hand, Yu Yu turned to Wan Zhao and said with a smile.

"Wan Daoyou, according to my deduction, there will be twenty-four top-grade spirit stones required for this. The Divine Tree with the power of thunder and lightning, you still need to give me three. ”

Hearing this, the corners of Wan Zhao's mouth twitched unconsciously. This superb spirit stone is easy to say, but this broken wood with the power of thunder and lightning was obtained at a great cost. The value of each root is by no means under the "empty dimensional crystal".
