Immediately, he crushed the fourth lucky bag, and a golden crystal crystal quickly condensed on the top of his palm.

[Name: Universe Source Energy Crystal]

[Grade: Eighty-one Immortal Emperor Level]

[Introduction: Special crystals containing abundant cosmic source energy can improve the level of the Immortal Emperor's soldiers]

[Note: Slowly improve]

"This thing..." Ye Feng thought about it, and finally, his eyes fell to the sky, where the Nine-Star Alchemy Furnace and the Forging Furnace were colliding with each other, "Who is it for? Forget it, open the fifth lucky bag first. Generally speaking,

These crystals all appear in pairs."

Click!

As Ye Feng crushed the fifth lucky bag, another cosmic-level source energy crystal appeared.

"really!"

Ye Feng twitched the corner of his mouth, "In that case, these two source energy crystals should be used to upgrade the nine-star alchemy furnace and the forging furnace! However, the improvement effect of this crystal is slow, and it cannot directly make them break through to eight.

The eleventh-level Immortal Emperor Weapons can be continuously improved until they all become the Eighty-one-level Immortal Emperor Weapons."

Thinking of this, he shouted to the sky:

"Stop fighting!"

"If we continue fighting like this, we won't be able to kill anyone."

"So, come down!"

Hearing the sound, the forging furnace and the Nine-Star Alchemy Furnace were startled for a moment, and then, like little puppies being called by their master, they came to Ye Feng's side in a hurry.

"These are two cosmic source energy crystals, one for each of you two brothers. Make a breakthrough, do you understand?"

After saying that, he caressed both of them respectively.

Buzz!

The nine-star alchemy furnace and the forging furnace were rising and falling, as if they were nodding. Immediately, the lids of the two furnaces opened, as if to say: Master, please feed us!

Seeing this, Ye Feng threw two cosmic energy crystals into the furnace and let them absorb them.

"Now, it's okay."

Ye Feng waved his hand, and the Nine-Star Alchemy Furnace and the Forging Furnace immediately left, suspended on the grass at the top of the mountain, continuously absorbing the energy of the cosmic source energy crystals. Mysterious golden lines appeared on the furnace body, making it look more and more mysterious.

"Continue studying the Book of Alchemy!"

Ye Feng said, looking through the book of elixirs, inputting the names of various medicinal materials, and obtaining countless elixirs. He felt that this book became more and more pleasing to the eye.

Soon, he thought of something.

"The Nine-Star Alchemy Furnace can also deduce elixir recipes, and so can the book of elixir recipes. So, if I fuse the two, can I succeed? After success, can the effect of deducing the elixir recipe be further improved?"

Thinking of this, Ye Feng was looking forward to it.

He immediately sat cross-legged on the ground, drank a cup of enlightenment tea, raised his understanding to the limit, and began to deduce the feasible method of integrating the two.
