Lin Yun took the box over and observed it carefully. The surface of the box was engraved with delicate patterns, and the lid of the box was engraved with arrays, which seemed to seal something inside.
I don't know what material the box is made of, blocking Lin Yun's Celestial Eye and soul power.
Lin Yun was not in a hurry and began to decipher the formation patterns on it.
Only a quarter of an hour later, the array pattern was cracked.
But before Lin Yun could breathe a sigh of relief, he immediately felt something was wrong.
A wave of heat rushed out from the gap in the box.
"Is there something in there?"
Lin Yun immediately stayed away from the box and said.
At this time, the mixed spiritual fire in Lin Yun's body was still trembling slightly.
"Is it possible that the fire inside is strange?"
Lin Yun felt the trembling of the mixed spiritual fire in his body and said.
Then, Lin Yun moved his fingers slightly, and formations appeared one after another, and a formation was arranged directly around the box.
Lin Yun slowly retreated. After retreating to a safe distance, Lin Yun used his soul power to open the box.
"Crack!"
As soon as the box was opened, first a bolt of lightning appeared, and then a red flame appeared inside the box.
The high temperature of this flame instantly turned the box into ashes, and the flame appeared in front of Lin Yun.
"Heavenly Thunder and Earth's Heart Fire!"
Lin Yun looked at the red flame surrounded by lightning and recognized the identity of the flame at a glance.
This is the Heavenly Thunder Earth Heart Fire that ranks thirty-one on the Heavenly Fire List.
The Heavenly Thunder and the Earth's Core Fire, as the name suggests, are the flames formed by the combination of the Heavenly Thunder and the Earth's Core Fire. Generally, when passing through the heavenly tribulation, in the tribulation cloud, endless lightning gathers, and a wisp of flame will appear.
And this flame will usually extinguish quickly. If it does not extinguish and falls to the ground, it will gradually extinguish because there is no energy provided by the flame.
Therefore, there is only one way to overcome the tribulation in a volcano or a place with abundant fire spiritual energy. Only in this way will this ray of flame absorb the fire spiritual energy and not extinguish, but will slowly grow stronger. But this is not enough. In the end, this A wisp of flame enters the volcano and follows the volcano channel into the center of the earth. Inside the center of the earth, this wisp of flame will continue to grow and eventually become a sky thunder fire.
Logically speaking, this is usually the case, and if the Heavenly Thunder Fire finds an Earth Fire that is comparable to itself, it will merge with it, and finally become the Heaven Thunder Earth Heart Fire. This process is very critical. If the Earth Fire is weak, it will Being swallowed up by the sky thunder and fire, it is impossible to fuse. If the earth fire is strong, it will swallow up the sky thunder and fire. Therefore, it must be equally matched, and the earth fire is already rare. It is even more difficult to meet an equally matched person. With this difficulty, this The birth of this flame is no less than the Nine Nether Demon Flame.
But now, this thunder and fire in the sky is right in front of him.
"Okay, after swallowing this flame, my strength can definitely reach the next level."
Lin Yun said.
But now is not the time to devour it. Although the mixed spiritual fire in Lin Yun's body is much more powerful than the sky thunder and earth fire, Lin Yun does not dare to take risks. After all, it is the flame that combines the sky thunder and the earth fire. I don't know how powerful he is. No matter how big it is, a lion fights a rabbit with all his strength.
At this time, Tianlei Dixinhuo stayed quietly in the formation, and there was no problem.
Later, after Lin Yun came out of the stone plate on the avenue, he flew towards the nearest city. He was going to buy some ice-type elixirs and refine them into elixirs to suppress the heat of the Heavenly Thunder and Earth's Heart Fire.
Lin Yun also changed his appearance on the flying boat. In this case, coupled with the isolation jade talisman, the people of the mythical beast clan would not be able to recognize him at all.
When approaching the city, Lin Yun put away the airship and entered the city on foot.
Lin Yun's goal was clear and he directly entered the largest chamber of commerce in the city.
"Sir, what do you need?"
A maid immediately came up to entertain Lin Yun.
"I need a lot of ice-based elixirs, are they available here?"
Lin Yun asked.
"Yes, sir, please come with me to the third floor."
the maid said.
Lin Yun nodded, followed the maid to the third floor, and entered a room.
And in this room, there are countless ice-type elixirs.
Because there are not many people who practice ice attributes, there is no one here.
"How much do guests need?"
the maid asked.
"I want them all."
Lin Yun said.
"Okay, sir, I want everything!"
The maid reacted and said.
"That's right. I want them all. Put them away and pay the bill."
After Lin Yun finished speaking, he left the room directly, leaving the maid in the room confused.
But the work efficiency was still good. After a while, a storage ring was delivered to Lin Yun's hand.
"Sir, they are all here. You need to pay. The total is 200 million Spiritual Essence Pills."
the maid said.
Lin Yun took the storage ring, looked at the elixir inside, nodded with satisfaction, and directly placed a storage ring on the table.
"Click it."
Lin Yun said.
The maid picked up the ring and took a look inside. The amount of Lingyuan Dan inside made her feel dazed for a moment.
"Okay, the number is correct."
The maid looked at it for a few breaths and then said.
Upon hearing this, Lin Yun immediately stood up and left here.
After purchasing the elixir, Lin Yun did not delay and went directly out of the city and entered the stone plate of the avenue in a hidden place.
"Old Bai, how are you? Is there anything going on with Tian Lei Di Xin Huo?"
Lin Yun asked hurriedly as soon as he entered the stone plate of the avenue.
"No, it's been quiet."
Bai Lao said.
Lin Yun also glanced over there, and the inner fire of Tianlei and Earth was still burning quietly in the formation.
"It's strange. Aren't the other strange fires extremely violent once they are released? Why is this one so quiet?"
Lin Yun looked at the Tianlei Dixinhuo in the formation and said in his heart.
But Lin Yun didn't have the intention to explore it, thinking that the fire in the heart of the sky and the earth must have been sealed for too long, and its strength was greatly reduced.
Afterwards, Lin Yun took out the alchemy furnace, opened the prescriptions obtained in the tomb, and began to look for ice-based elixirs.
"found it!"
Lin Yun found an eight-pattern elixir called Ice Spirit Pill in the elixir.
"That's it!"
Lin Yun thought for a while and realized that the eight-pattern elixir was also possible, so he began to look for the elixir needed to refine the elixir.
Soon, more than two hundred elixirs were placed in front of Lin Yun.
Putting so many ice-attribute elixirs together, the cold air emitted caused the surrounding grass to begin to freeze with frost.
Afterwards, Lin Yun began to preheat the elixir furnace and looked at the records on the elixir recipe to see how the elixir should be refined.
While Lin Yun was preheating the alchemy furnace, Lei Di Xinhuo seemed to be observing Lin Yun that day, and the flames were flickering.
