Three days later, Yang Buyi's body completely recovered, so Yirong called him to go to the flame cave.

"We will call for harassment outside later. We all have the best flying skills, and they can't catch up with us." Yang Buyi reminded.

"I understand." Yirong nodded.

"The mountain flowers are already brilliant, and half of the sky is already dyed with redness. I think the fire will make the sky erupt, and the passage will open at that time."

Yang Buyi looked at the fiery red flowers all over the mountains and the sky that was reddishly reflected by the red flowers, and guessed in his heart.

"The mountains and flowers are brilliant for one year, and the clouds are red for two years. Now nine months have passed, and I think it should be soon." Yirong looked at the red sky with a hint of joy in his eyes.

"Wait until I go and put poison pills!" She said, then flew towards the flame cave. When she reached the entrance of the cave, she shot out four black pills and then flew away at a very fast speed.

The next moment, sharp anger erupted from the cave. A huge flame bird flapped its wings and flew out, opened its mouth and sprayed a gulp of flames in the direction of Yirong flying.

I was originally going to chase, but with a glance, I quickly saw Yang Buyi standing on the other side of Lingkong.

Yang Buyi looked at the flame bird with flames all over the body, felt the spiritual pressure that was several times stronger than the black-printed leopard, and couldn't help but feel secretly shocked.

He knew that the big guy in front of him was difficult to mess with and that he could not deal with.

"Cry!"

The flame bird screamed at a very fast speed. It appeared a hundred meters away from Yang Buyi when it spread its wings. Then it opened its mouth and sprayed out a large area of ​​flames, burning it.

Yang Buyi's reaction was also quick. When it spread its wings, it had already used the Five Elements Sword Control Technique to escape far away.

The fire bird roared in the sky without a single blow, and was extremely furious.

The burning flames suddenly surged, and a stream of scorching wind and waves spread around with the extreme high temperature.

"This guy is going to be serious. The level ten monster is very fast, let alone a level ten flying monster. Don't be careless and activate the flying technique to the extreme!" Yi Rong's reminder came from afar.

Yang Buyi stared at the flaming bird, the size of a house, in front of him, with spiritual energy surging in his body, ready to deal with all attacks.

The flame bird was in full swing. Just as it was about to fly over, a low whine suddenly came from the cave. The slightly weak tone made the flame bird's eyes look a little shocked.

Immediately, I turned my head and screamed, and suddenly flew into the cave.

"It seems that the poison has worked, but I just don't know if I can put them down." Yi Rong flew over and said happily.

"I'll go over and take a look!" Yang Buyi said.

"Don't go, the monsters are in extreme anger and extremely dangerous." Yirong stopped him.

"Don't worry, I'll use the secret technique to pass." Yang Buyi smiled mysteriously and immediately used the light and shadow technique. A figure that was exactly the same as him appeared. Under his control, it slowly became transparent and quietly lurked over.

"What secret technique are you? It can actually differentiate with the help of light to create a movable shadow?" Yi Rong's eyes flashed slightly, and she was a little curious.

"This is called light and shadow technique. Although it has no lethality, it is sometimes very effective." Yang Buyi smiled, and was also a little surprised that she could see the secret of light and shadow technique at a glance.

While the two of them were talking, the transparent shadow had already floated into the cave.

There is also a red light reflected by magma in the cave, and the use of light and shadow technique will not be affected.

"They looked a little painful, and they were lying on the ground and looked a little weak." Through the light and shadow, Yang Buyi saw the situation inside.

"It seems that the poison pills I have refined are still very effective, but I don't know how many levels of strength they still have now." Yirong said with a smile.

"Huh? What is that?" Through the light and shadow, Yang Buyi's gaze suddenly froze.

"What did you find?" Yirong said curiously when Yang Buyi's body was so excited that he trembled.

"On the wall of the hot cave, there is a Ganoderma lucidum. It is three inches tall and is as red as a soldering iron. It has a faint red flame on the surface, which looks weird and magical. This is..."

"This is...Di Zhong Huozhi?!"

Yang Buyi was shocked all over, and he looked at each other with Yirong, and spoke in unison.

Its appearance is exactly the same as the Earth-center Fire Zhi recorded in the ancient foundation-building pill recipe.

"There is actually a fire radish in the center of the earth? It is one of the three main materials for refining the ancient foundation-building pill." Yirong was also quite surprised, with a hint of joy in his eyes.

"Let my shadow get closer, take a closer look!" Yang Buyi suppressed his excitement and controlled the shadow to get closer slowly, but he only took two steps forward.

The largest flaming bird suddenly looked up and seemed to notice something. A trace of anger flashed in its eyes. It opened its sharp mouth and sprayed a flame not far away.

The light and shadow were burned clean in an instant.

The contact was cut off, and Yang Buyi's mind also shook slightly.

"Now don't show desire to the Earth-center Fire Zhi, otherwise those flame birds will find it, and they may eat it." Yirong looked at Yang Buyi with an excited face and reminded solemnly.

"I know!" Yang Buyi nodded and quickly calmed down his excitement.

"The three main materials for refining the ancient foundation-building pill are very difficult to find. Now the earth-center fire zhi is in place. As long as the remaining ones are found in the flower of the void and the fairy fruit of heaven and earth, you can refine the ancient foundation-building pill. If you can find these last two spiritual medicines, you will have hope of building the foundation!" Yirong smiled slightly and was happy for him.

"Hope, otherwise you will have to endure the life span." Yang Buyi also had a hint of hot hope in his wry smile. The appearance of the Earth-center Fire Zhi injected him with a dose of heart-boosting medicine, which made him extremely excited.

Now he has both hope and nervousness in his heart. He is afraid that the flame bird will eat the earth's center of fire. If so, then hope will be shattered again.

"Let's go and tease them, and see how much their strength has been reduced!" Yang Buyi said, flew over first, and Yirong followed closely behind.

call out!

A sharp Five Elements Sword Qi turned into a tiny flying sword and suddenly rushed into the cave. Under Yang Buyi's control, he strangled it wildly inside.

Suddenly, there was a constant cry of crying inside.

Huh!

Then two flame birds rushed out crazily, their eyes were blood red and almost crazy. When they came out, they used all their strength. Large pieces of flames roared and swept through most of the sky.

"No, the strength of this flame bird has not weakened much. It seems that although the pills this time hurt them, they are not fatal. Let's go back and I will continue to study them carefully. I don't believe that I can't refine a more powerful poison pill."

Yirong's face was bulging, and the flame bird hid in the cave was like blocking their way, and they had to be driven out.

"Okay, let's go back and harass them every once in a while from now on, so as to reduce their vigilance."

Yang Buyi said that, and left Yirong Fei.
Chapter completed!
