Well. Lin Yun nodded.

"By the way, the representatives of their company are in the imperial capital now, if Brother Yun has time and intentions, he can talk to them face-to-face. Liu Bo said.

"I don't have time these days, so let's do it, after a week, I'll leave an hour for them, and after a week, at noon, you bring them over. Lin Yun said.

Lin Yun's next time, if he wants to impact the senior alchemist, of course he is not available.

"Good. Liu Bo should go down.

After Liu Bo left, Lin Yun came to the practice room on the second floor of the villa and prepared to start alchemy.

The next thing for Lin Yun is to put aside all distractions and impact the senior alchemist!

Inside the practice room.

Lin Yun put the 9 beads of high-grade medicinal materials, and the intermediate medicinal materials and primary medicinal materials that he needed, beside him.

To refine a high-grade pill, in addition to one high-grade medicinal material, it is also necessary to supplement it with two beads of intermediate medicinal materials, plus 4-5 beads of primary medicinal materials.

"Whew, let's get started. ”

After Lin Yun's voice fell, he directly activated the internal force to urge the Danhuo.

Rumble.

A faint pill fire rose from Lin Yun's hand.

This Dan fire is urged by internal force.

Immediately afterwards, Lin Yun directly threw the medicinal materials he needed into the medicine tripod, and the refining began!

About 4 hours later, the first refining was declared a failure.

Such a failure was completely expected by Lin Yun.

After an hour of rest and adjustment, Lin Yun immediately began refining for the second time after recovering his state to fullness.

In the blink of an eye, another four and a half hours passed.

At this time, Lin Yun's forehead was covered with beads of sweat.

Refining high-grade pills is a great test of internal strength, with Lin Yun's golden pill strength, refining high-grade pills is very reluctant, even if it is refined once, it can exhaust Lin Yun's internal strength, and it is not enough.

Unless you reach the Yuan Infant, with the strong internal strength of the Yuan Infant, refining the high-grade pill can be easier.

Fortunately, Lin Yun's jade pendant, the aura of heaven and earth has been replenished enough, and Lin Yun used the aura of heaven and earth in the jade pendant to replenish his internal strength while refining the pill.

But this will divide part of the energy, and it will also lead to an increase in the difficulty of alchemy!

Fail!

Soon, the second refining also failed.

Although Lin Yun had long expected that he would not succeed easily.

However, when failure came, Lin Yun was inevitably very frustrated.

Moreover, the medicinal materials for refining high-grade pills were all obtained by Lin Yun with great difficulty, and after failure, they turned into ashes, and it was false to say that he was not distressed.

At this time, the sky outside the window has turned white, and a new day has come.

"Take a break, come again!" Lin Yun wiped the beads of sweat from his forehead, and his tone was firm.

Immediately afterwards, Lin Yun ran the exercises, absorbed the heaven and earth aura in the jade pendant, replenished the internal force in the body, and restored the state to fullness.

While recovering his state, Lin Yun was also thinking about the mistakes he had just refined and reflecting.

After an hour of state adjustment, the third refining opening began.

Fail!

Fail!

Fail!

It was another three consecutive refining, all of which ended in failure, and each time he refined, Lin Yun was exhausted.

Of course, Lin Yun was also in the midst of failure, summed up his experience, adjusted the control of the Danhuo, and looked for the best Danhuo size.

in the room.

"There are only three high-grade medicinal herbs left. ”

Lin Yun wiped his sweat while glancing at the medicinal herbs placed next to him.

This means that Lin Yun only has three chances left.

"Ding-dong, ding-dong. ”

Just then, the doorbell rang downstairs.

After Lin Yun heard the voice, he got up and went to open the door.

Lin Yun's cheeks were still pale, it was really refining high-grade pills, and the consumption of internal power was too terrifying.

After the door is opened.

What caught his eye was not someone Lin Yun was familiar with, but a middle-aged man in a white robe.

The cuffs of the robe are tattooed with a golden lotus.

"Jin Lian, are you from the temple?" Lin Yun exclaimed.

Lin Yun had been in contact with the people of the temple once, so Lin Yun knew that the cuffs were tattooed with golden lotus, and this was the costume of the temple!

"It seems that you still have some insight to know that I am a member of the Temple. The middle-aged man was indifferent.

"I don't know what the temple envoy is talking about?" Lin Yun looked at him calmly.

"This is, an invitation to the Temple Tryouts. ”

The middle-aged man handed a gilded letter to Lin Yun.

"Invitation?" Lin Yun's eyes lit up, and at the same time he understood the meaning of this person's coming.

"On the invitation, there is a date and a meeting place, remember, this is a rare opportunity. The man said slowly.

"Thank you. ”

Lin Yun accepted the invitation.

After the middle-aged man handed Lin Yun the invitation, he didn't say a word more, and turned around and left directly.

Lin Yun closed the door, then opened the invitation, glanced at the time and place, and then remembered it in his heart.

Counting the time, it will be two months and a few days.

There is not much time left for Lin Yun to improve.

"Hongling, thank you. Lin Yun muttered.

Lin Yun knew that this invitation letter was mostly due to Hongling.

This also made Lin Yun even more curious about her identity, she actually had the ability to help herself get an invitation letter.

"Don't worry, when the time comes, I won't let you down. Lin Yun muttered.

Lin Yun stored the invitation in the jade pendant space and returned to the second floor.

"Go ahead. ”

Lin Yunpan sat on the ground, first adjusted his state, restored his state to fullness, and then continued to refine the pill.

An hour later, the sixth refining attempt began!

Rumble!

The flame of the Shadow Pill rose up, and Lin Yun immediately put the medicinal materials into the medicine tripod and began to refine it.

This time the refining lasted for seven hours.

Seven hours later.

This time the effect is very good, and it has persisted until the Ning Dan period!

In the medicine pod, the medicinal materials that have been refined begin to slowly condense and transform into a pill!

Lin Yun, who was sweating profusely, stared at the medicine pod with all his attention, observing the changes at all times.

In Lin Yun's heart, he kept praying that he must persevere!

This is the most promising one so far!

At this time, the medicine tripod suddenly began to crack, and countless cracks were derived.

"What's going on!"

Seeing the cracking of the medicine tripod, Lin Yun's face suddenly changed.

The next moment.

Rumble!

A huge explosion suddenly occurred, and the entire medicine pod exploded with a bang.

The casualness of the medicine tripod splashed in the house, and the whole house was in a mess, like the scene of an explosion.

"Damn! Damn!"

Even though Lin Yun's current temperament couldn't help but scold again and again.

It wasn't Lin Yundan's failure to control the fire just now, which led to failure.

It was that the medicine tripod could not withstand the test of the Dan fire, which caused the medicine tripod to shatter and explode.

Can Lin Yun not be angry?

Immediately after, Lin Yun hurriedly looked to the side, wanting to see if the remaining three high-grade medicinal herbs had been damaged in the explosion.

Fortunately, none of these three high-grade medicinal herbs have been damaged, which can be regarded as a blessing in misfortune.

As for Lin Yun, this explosion naturally didn't cause damage to him, it just made him scorched black and looked embarrassed.

"If you want to refine a high-grade pill, you have to find a better pill tripod, this kind of ordinary pill tripod can't stand such a high-intensity torture of the pill fire. Lin Yun said helplessly.
