boom!

The king of the ancient monsters flicked his tail fiercely, and sent the flat-headed brother flying away. He fell into an unknown corner and was buried in a large area of ​​ruins.

"What happened?"

"Why did Brother Flathead get hung up again?"

"That's how he is. Although his strength is average, he always likes to challenge the strong. The key is that after you beat him up, he is still stubborn."

"Hey, what kind of spiritual beast is that?"

The members of the Piaomiao Holy Sect noticed the ferocious battle between Brother Pingtou and the King of Ancient Giant Beasts, and they were all curious about this new giant beast.

"No need to guess, that is the king of ancient giant beasts, the eighty-first-level Immortal Emperor, whom I have just conquered. Now it has become a member of the Spirit Beast Pavilion."

Ye Feng explained.

Immediately, he didn't bother to care about Brother Pingtou and the King of Ancient Giant Beasts who were fighting on the horizon. Instead, he called Hu Dahong to popularize the secret realm of the ancient world.

"In the future, you can enter the ancient world to practice, compete with ancient giant beasts, and improve yourself."

After that, Ye Feng returned to Piaomiao Peak.

The rewards for the first sub-task are five lucky bags of different colors. They are an eighty-one-level immortal emperor-level top-level sect-protecting formation, a fusion pill, a soul-fixing bead, and a small piece of Luo Guanhua.

The Taoist tablet fragment of the true soul mark contains the ancient world of the 81st-level Immortal Emperor, the King of Ancient Giant Beasts.

Except for Fusion Pill, the other four rewards have been digested by Ye Feng.

Now, he is preparing to retreat.

"I have been grinding for more than half a year, but the Law of Cause and Effect has only fused more than 3,000 strands. The speed is too slow. Now I can just take the Fusion Pill to get an acceleration effect that lasts for half a month. Maybe I can break through."

"However, before taking it, you should research the Fusion Pill first to see if it can be copied."

Ye Feng chuckled.

Imitation? He likes it best!

As long as a low-end version of Fusion Pill can be developed, even though the efficacy is not as strong as the original version, as long as it can be continuously refined and has no drug resistance, that will be enough.

If the quality is not enough, then quantity will be enough.

With that said, he started researching.

In order to make the research smoother, Ye Feng directly stopped the Nine-Star Alchemy Furnace and asked it to come to him. He put the Fusion Pill into the forging furnace for analysis.

Half a day later.

The Nine-Star Alchemy Furnace said: "Boss, this elixir contains only a hundred types of medicinal materials, which can be found in the ancient medicine garden of Qiyun Tianzun."

"Oh?" Ye Feng's eyes lit up, "Can you refine it?"

"I can give it a try."

The Nine-Star Alchemy Furnace opened the ancient medicine garden of Qi Yun Tianzun, took out one hundred kinds of elixirs that were over a million years old, and started refining them directly.

Ye Feng was waiting aside.

The whole process lasted half a day.

When the Nine-Star Alchemy Furnace opened the lid again, a cloud of black smoke came out.

"Boss, I failed."

"Failed? It's okay, continue!"

The Ancient Medicine Garden has abundant reserves of elixirs and can withstand large amounts of consumption. Ye Feng does not feel distressed.

It's half a day later again.

puff!

A fart-like sound sounded, and the Nine-Star Alchemy Furnace failed to refine again, emitting large amounts of black smoke. However, there were some more golden medicine residues in the alchemy furnace, which meant that the refining this time had progressed.

"Don't worry, come again."

Ye Feng patted the lid of the Nine-Star Alchemy Furnace.

"okay!"

The Nine-Star Alchemy Furnace maintains the appearance of the alchemy furnace itself. In this case, the refining effect is better.

Tried again and again, failed again and again.

Ye Feng assisted from the side and helped the Nine-Star Alchemy Furnace to modify the parameters. Finally, after the hundredth test, a furnace of pale golden fusion elixir was successfully refined.

"Success?!"

"That's wrong. The fusion elixir given by the system looks like a milk candy and is milky white, but why is the one refined in the Nine-Star Alchemy Furnace light golden?"

Ye Feng was suspicious and opened his eyes of insight.

[Name: Fusion Pill]

[Grade: Pseudo-Tiandao Grade]

[Introduction: A special elixir, after taking it, can accelerate the fusion of laws, and the duration is one month]

[Note: imitation version]

This is an imitation fusion pill that he and the Nine-Star Alchemy Furnace worked together to refine. The fusion pill rewarded by the system is the Tiandao level. The one they refined is the pseudo-Tiandao level, which is half a level lower, but the duration of the drug's effect is extended to

One month is not bad.

"Very good, you continue to study fusion pills, I will take these pills first and try the effect."

Ye Feng smiled.

"Okay!" The nine-star alchemy furnace returned to the form of a child, nodded, and returned to the ancient medicine garden to continue studying the imitation version of the fusion elixir.

The top of Piaomiao Peak.

Ye Feng looked at the table.

There were eleven pills lying there, one of which was a fusion pill rewarded by the system, and the remaining ten were imitation fusion pills that he and the Nine-Star Alchemy Furnace refined.

"Hopefully it will be successful."

Ye Feng was the first to take the fusion pill rewarded by the system. The law of cause and effect in his body suddenly trembled, giving him a mysterious feeling. After experiencing reincarnations again and again, he gained a deeper understanding of cause and effect. The law of cause and effect in his body moved ten times faster than before.

Fusion.

Half a month later.

Ye Feng discovered that the efficacy of the medicine was lost and the integration of the laws in the body slowed down. Fortunately, the law of cause and effect has now been integrated into eight thousand strands.

"Boss, I'm done!"

At this time, the Nine-Star Alchemy Furnace left and returned, stretching out its fleshy little hand. Three milky white pills appeared in the palm, which were the same as the fusion pills rewarded by the system.

Ye Feng quickly opened his eyes of insight.

[Name: Fusion Pill]

[Grade: Tiandao level]

[Introduction: A special elixir, after taking it, can accelerate the fusion of laws. The duration is three days, but the growth rate of the fusion laws is five times faster than before]

[Note: Enhanced version]

After reading the information, Ye Feng was overjoyed.

Although the time limit has dropped from half a month to three days in the original version, the speed of law fusion has increased five times. In total, this elixir is better than the original version.

"You boy, you are amazing!"

Ye Feng couldn't help but praise him.

"Haha, that's not true!" The Nine-Star Alchemy Furnace turned red after being praised by Ye Feng and scratched his head.

"Okay, you continue to refine the enhanced version of the fusion pill, and get me at least a hundred pills in stock."

Ye Feng gave the order.

He will have to create new laws in the future, and at that time, he will still have to integrate those laws.

Therefore, Fusion Pill is indispensable.

"Take orders!"

The nine-star alchemy furnace left the elixir and continued running back to the ancient medicine garden to refine the elixir, looking very excited.

Since he has been practicing alchemy recently to promote the absorption of cosmic source energy crystals in his body, his cultivation has reached the peak of the seventy-eighth Immortal Emperor.

Soon after, he was able to break through the 81st level.

Looking at the back of the nine-star alchemy furnace, Ye Feng showed a smile of relief and satisfaction, put away the pseudo-Tiandao level fusion pill, and took the enhanced version of the fusion pill instead.

hiss!

As soon as the pill was taken, Ye Feng discovered that the fusion speed of the law of cause and effect in his body increased sharply, reaching five times that of taking the original version of the fusion pill, making the total increase speed reach fifty times, which can save a lot of time.

Time flies like an arrow, and time flies like a shuttle.
