After a lot of effort to find the golden needle back, Tang Zheng cleaned up the battlefield and cleaned up the traces of the formation.

He casually threw the tree spirit seed to Yiyi: "Oh, for you, I didn't expect this harvest to be cheaper for you in the end." ”

"What is this?" Yi Yi looked at the seed in his hand curiously, the seed was like an olive pit, the whole body was emerald green, but it was poked by Tang Zheng, and some green juice flowed out.

"The essence core of the tree spirit is also the essence of its whole body. Tang Zheng replied, picked up Yi Yi and pointed to the essence core and said: "The essence core, the demon pill, the ghost element, and the strange marrow are the core treasures of the four categories of goblins and ghosts, and this is the essence core of the tree spirit, and this one essence core alone is worth a lot of money." ”

"Then why didn't the wolf we killed before have a demon pill?" Yiyi asked curiously.

Tang Zheng smiled: "Spirits have no life, their blood and qi are insufficient and their spiritual energy is easy to gather, so it is easier to gather essence cores, but because of this, most of the other parts of their bodies are of little value, and most of the essence is concentrated here." Monsters are different from spirits, they are born with flesh and blood, and there is no soul and life, and the aura is integrated into the whole body, so the flesh and fur of the whole body are valuable, but the cultivation of the demon pill is not easy, if there is really one, it must also be a very strong existence. If we encounter such a demon beast, we really don't know how to die. Although this tree spirit is ranked as a low-grade tree, the life span is obviously not short, the days are long, and it is not uncommon to produce a sperm core, but the time to bear fruit is not long, it is smaller, I think this one is worth three or four hundred dollars at most. ”

"Is it any use?"

"It's very useful, whether it's used for alchemy and medicine, or for drawing runes, it has a role, just look at the different uses, and the effects are different. This tree spirit is ordinary in nature, as a lower grade, and has no special effect, but it is rich in spirituality and full of wood energy. ”

"It's such a good thing, my brother still sells it. Yi Yi put his arm around Tang Zheng's neck and said.

Although the little guy is a little naughty, he is also sensible, knowing that Tang Zheng came to ask for money, this essence core is the biggest harvest of Tang Zheng, if she is allowed to eat it, won't she die?

Tang Zai scratched her nose and smiled: "Silly girl, you eat it is the best use of it." Besides, this essence core was pierced by my finger just now, and the essence has begun to leak, if you don't eat it again, it won't be worth it until it leaks. ”

Although items such as the Essence Core Demon Pill are valuable, they are also the life of the monster, and they are often used to fight to the death before they die, so it is not easy to obtain a complete Essence Core Demon Pill. Tang Zheng is not strong enough in the end, and he can only use the golden needle in the face of that essence core attack, if he was a little reluctant in his heart at that time, he is afraid that he will die now.

Of course, part of the reason why he can be so willing is that with Yi Yi here, this essence core is at least not afraid of losing much.

Hearing this, Yi Yi didn't hesitate anymore and swallowed the essence core in one gulp.

After swallowing the essence core, Yiyi's face immediately flashed with green energy, a large amount of spiritual energy filled her body, and her body grew like an inflatable doll, and the small dot that was originally only twenty centimeters suddenly became the size of a newborn baby, and it was more than doubled.

Not only that, but the skin of the whole body has become crystal clear, and the brilliance is faintly visible under the jade white skin.

Seeing this scene, Tang Zheng frowned: "The aura is full of body, virtual but not real, scattered but not condensed......"

He swung the blue light sword and slashed at his wrist, cutting a deep wound, and pointed it at Yiyi: "Yiyi, drink!"

Yi Yi only felt empty in his stomach at this time, and he was indescribably hungry, and when he saw Tang Zheng's arm coming, he sucked at Tang Zheng's blood vessels desperately.

This time, her blood sucking was not more ferocious than before, but it was much more ferocious, and Tang Zheng only felt that the blood in her whole body seemed to be flowing towards Yiyi's mouth.

Tang Zheng knew that the Dao was not good, the more aura Yi absorbed, the more blood qi that needed to be nourished, the aura of this tree spirit essence core was extremely large, and even the blood he needed to pay was greatly increased, if she was really allowed to suck it like this, it would cause great loss to Tang Zai's body, and even if she cultivated for a few months, she might not be able to make up for it.

He knew that he was still reckless this time, and although he had already read what the master had said, there was always something that the teachers had not had time to say, and they could only understand it when they encountered it.

At this moment, seeing that Yi Yi was still sucking blood, the flesh and blood of his whole body were gradually filled, no longer like a crystal doll as before, but a pair of eyes gradually appeared red, revealing a trace of confusion.

Tang Zai knew that this was her critical moment, and it was definitely not suitable to disturb, so she simply gritted her teeth and took out a demon blood pill for herself to swallow.

This Demon Blood Pill is refined with blood refining demon pills, and after using it, the blood qi rises greatly, it is the essence of blood refining, which is suitable for nourishing Yiyi's blood qi, even if it is weak afterwards, at least it will not hurt the origin.

At this moment, under the effect of the Blood Refining Demon Pill, the blood qi in Tang Zheng's body soared, and at the same time, Yi Yi was also crazy about sucking blood, Tang Zheng's body was like a leaky pool, and there was a faucet on it, releasing water while leaking.

It wasn't until Yiyi's crystal-clear color gradually disappeared and regained its ruddy color that the little guy finally let go of his hand, and his originally confused scarlet eyes finally returned to clarity.

She let out a long breath, tilted her head, and fell asleep.

"......" watched the little things fall asleep when they were full of food and drink, and Tang Zheng was also speechless.

At this time, most of the demonic blood pill demon power had been absorbed by Yi Yi, and since there was still a trace of medicinal power left, Tang Zheng had not yet felt its side effects, but felt that he was in good spirits.

However, Tang Zheng also knew that this time would not be very long, and he didn't go hunting demon beasts anymore, just packed up his things, walked around the valley with Yi Yi on his back, and it didn't take long to return to the waterhole.

It's just that the tiger at the top of the peak is gone, and it may have returned to the cave to rest.

Tang Zheng walked towards the mountain.

Walking all the way up the mountain road paved with black stone slabs, when he walked to a distance of about one-third from the mountain peak, Tang Zheng saw a stone tablet with three big characters written on the tablet "Town Demon Tablet".

Stone monuments stretch across the road to the top of the mountain.

Behind the stele, the black slabs are transformed into red slabs, and the black and red strip is a clear dividing line, separating the peak and the bottom of the peak into two worlds.

This is the only psychic high-grade demon tiger imprisoned in the Tiger Roaring Valley.

Crossing the boundary means passing through the protection of the formation and entering the demon tiger cage.

Every year, a large number of students from the Moon Washing Academy enter the Demon Tiger Cage to duel with the Demon Tiger, and although most of the time they lose, it doesn't matter whether they win or lose here.

For the students, this is a necessary experience for them to grow up, and only after truly seeing the power of psychic high-level creatures can they truly understand what they can and cannot do in future trials.

Standing in front of the stone stele, Tang Zheng looked at the stone stele with deep eyes, and he didn't know what he was thinking in his mind.

After a few moments, he suddenly took a step forward.

He was stepping on the red slate.

"Roar!"

A tiger roared from the peak.

The tiger had reappeared, standing on a large rock, staring at Tang Zheng.

Tang Zheng stepped on the red board with his left foot and looked at the blackboard with his right foot, separating both sides of the boundary line, and also looked at the tiger with cold eyes.

One man and one tiger are facing each other like this.

Tang Zheng slowly raised his right foot and took another step forward.

At this point, his entire body was in the realm.

The tiger still didn't move, just looked at Tang Zheng.

Tang Zheng took another step.

Step 3!

Step 4!

Tang Zheng walked forward cautiously step by step, staring at the demon tiger.

All the way to the tenth step.

The demon tiger finally moved.

It slammed into the air, leaping from the summit.

At the same time, Tang Zheng retreated.

He quits the first step!

"Roar!"

The fierce tiger let out a fierce roar, like thunder, and shocked Tang Zheng to a complete stagnate.

Just about to launch the purple lightning indulging method, it actually dissipated in this roar.

It's too late to run, and he'll retreat!

Step 2: Exit.

The demon tiger's body was completely volleyed, and the wind was surging under his feet.

The third step, the fourth step, the fifth step, the sixth step!

Taking four steps back, the body of the demon tiger drew a lightning-like light and shadow in the air, and swooped down, like a terrifying rainbow, and instantly passed through the hundred-meter-long sky!

He took a seventh step back.

The demon tiger is approaching, and the wind is blowing!

He took an eighth step back, his claws raised, and slapped at him violently.

Tang Zheng's body leaned back sharply, and the tiger's claws brushed his face, swept over his legs, and fell to the ground, bringing up a splash of blood.

Rumble!

Wind and thunder on the ground!

The tiger's claws hit the ground, bringing up the wind and clouds, wrapping up the sand and stones, and attacking the Tang Tribulation!

A large amount of rubble struck him like a bullet, and countless blood sprays were shot out in a flutter.

Tang Zheng vomited blood and flew back.

Step 9!

One foot out of bounds.

At this moment, a piece of ground thorns shot out from the ground on the stone slab, hitting the soles of Tang Zheng's feet.

Tang Zheng jumped up.

The demon tiger had already jumped up at the same time, opening its mouth and biting at Tang Zheng.

Being in the air, Tang Zheng no longer had time to dodge, so he could only tilt his body as much as possible and lean back with all his might.

At that moment, time passed so slowly.

His body moved backwards in the air, and in front of him was the rapid pounce of the descending tiger.

The huge tiger head opened against Tang Zheng's throat, revealing sharp and hideous teeth.

Tang Zheng had no doubt that if he let it bite this vital point, even with his current body, there would be only one way to die.

The sharp teeth widened in the pupils, occupying almost the entire field of vision, filling all the worldly realms of the Tang Tribulation, with a sharp cold glow, and the smile of death......

A little cold, it has touched his body.

At the moment when the sharp teeth reached the body, a huge golden net that enveloped the entire mountain suddenly appeared.

Tang Zheng's body passed through the golden net as if it were passing through the air.

The tiger's head is crashing into the net.

The lightning flashed, wandering on the Internet, and instantly converged into a huge electric light and fiercely slashed down, landing on the tiger.

"Roar!" the demon tiger let out a cry of pain and misery.

At this time, Tang Zheng finally flew out of bounds and fell heavily to the ground, his inertia did not decrease, and he sat on the ground with his buttocks.

Then he saw that the tiger did not flinch under the lightning.

It slammed headlong into the net, roaring wildly at Tang Zheng, and let out a terrifying roar.

It bangs its head against the net!

It tore the net with its claws!

It bites the net with its teeth!

Crazy!

It was greeted by even more ferocious and merciless lightning strikes.

The thunder and lightning in the sky slashed mercilessly at it, tearing its flesh apart, scorching its fur, and even exposing its bones.

It didn't finally fall until it couldn't hold it anymore.

It gasped, its eyes still on Tang Zheng, Tang Zheng could see that it was full of hatred!

Tang Zheng also looked at him and didn't say anything.

One person and one tiger, just separated by a net, are far away from each other.

After a long time, the demon tiger stood up again.

It staggered towards the peak, stumbling slightly.

Tang Zheng looked at its back, watched it walk back to the top of the mountain step by step, and disappeared to the top of the peak.

An unprecedented sense of exhaustion permeated his body, and Tang Zheng knew that his trip to Tiger Roaring Valley had come to an end.
