Li Ran stepped forward and leaned against Zhang Hao's side, "I heard that the boy is a second-grade immortal root, and he was originally going to be brought directly into the inner door, but he was bitten to death by a wolf on the mountain!"

The second grade immortal root is even one level higher than Han Shi!

"How fast did you say the cultivation speed of the second-grade immortal root?" Li Ran asked Zhang Hao enviously.

"It won't take half a year to break through to the fourth layer of Qi training!" Zhang Hao still remembered that it took Han Shi less than a year to break through to the fourth layer of Qi training.

"Half a year!" Li Ran exclaimed in surprise, then covered her mouth and muttered, "It took me three years to break through to the third layer of qi training, and I don't know how many years it will take to break through to the fourth layer of qi training." ”

Zhang Hao wanted to tell her that it would take you four years of hard cultivation to break through to the fourth level of Qi cultivation, but he hesitated and didn't say anything.

Because next, it would take her eight years to break through to the fifth layer of Qi training, and then it would take sixteen years to break through to the sixth layer of Qi training, and then double the cultivation time and go up......

"Senior Brother Zhao Dao is dead!" Li Ran said suddenly.

Zhang Hao didn't answer, although he didn't have much contact with Zhao Dao, but after all, he was someone he knew, and he was still a little sentimental about his death.

As soon as I received the Bigu Dan, someone came to inform: "Senior Sister summons!"

Zhang Hao and Li Ran followed and went to see the senior sister.

In the cave in the middle of the ninth layer, Han Shi was explaining something to the three disciples, when Zhang Hao and Li Ran walked in.

Zhang Hao pulled Li Ran to the side and waited for a while, and vaguely heard their conversation: Cave...... Bigu Dan...... One year ......

After a while, Han Shi turned his head to look at Zhang Hao and Li Ran, "You two follow them, and they will tell you how to do it." ”

Zhang Hao and Li Ran left with the three of them.

But these three people didn't seem to want to deal with Zhang Hao and Li Ran, and kept walking briskly in front of them, and they didn't say what they were going to do.

Li Ran was a little angry and wanted to ask, but was stopped by Zhang Hao.

The three of them led the way in front, walked out of the Thousand Caves Cliff, and went around the back mountain to the bottom of a waterfall.

The waterfall falls from the top of the cliff and rushes straight down, which is spectacular!

Zhang Hao still has some impressions of this waterfall, he has just entered the mountain gate and walked on the plank road, and he has seen it.

On the other side of the waterfall should be the stone chamber where new disciples comprehend the exercises.

Zhang Hao couldn't help but look up at the opposite side, the distance was a little far, and he only saw a winding black line on the cliff.

After that, go around the waterhole below the waterfall and you will see a hole.

Walking into the cave and following the passage, you soon came to an underground cave.

This cave is inlaid with many night pearls for illumination, and the light shines on the stone pillars, and under the refraction of the stone pillar crystals, it flashes with colorful colors.

"You follow suit!" one of them casually explained to Zhang Hao and Li Ran.

Then, the three of them sat cross-legged under a stone stalactite, and used their aura in their right hand to absorb something from the stone stalactite.

I saw a drop of milky white liquid slowly precipitating from the stone stalactite!

"Chalcedony!" Li Ran suddenly exclaimed, a little incredulous.

Chalcedony?Zhang Hao looked at Li Ran suspiciously.

Li Ran said in a low voice: "Chalcedony is the essence of this mountain range!"

But Zhang Hao still didn't understand much, so he wanted to ask.

"Hurry up and sit down and work, each person must absorb chalcedony every day and condense twenty Bigu Dan!" another person said in a deep voice.

Zhang Hao and Li Ran respectively came to sit cross-legged under a stone stalactite.

Zhang Hao looked up and saw that after the chalcedony was separated from the stone stalactite, it gradually turned from milky white to gray under the absorption of aura, and thus condensed from liquid into solid, which was the most common Bigu Dan.

"Bigu Dan is divided into lower grade, middle grade and upper grade, the lower grade can be full for one day, the middle grade can be full for ten days, and the upper grade can be full for 100 days, we only need to condense the lower grade Bigu Dan!" the man explained just now.

Zhang Hao took the opportunity to ask: "Then how can we condense the middle-grade Bigu Dan and the high-grade Bigu Dan?"

"One drop of chalcedony condenses the lower grade Bigu Dan, ten drops of chalcedony condenses the middle grade Bigu Dan, and 100 drops of chalcedony condenses the upper grade Bigu Dan. It's just that the cultivation of the two of you is too low, and you can't condense the middle-grade Bigu Dan and the high-grade Bigu Dan!" the man replied with a mockery.

Zhang Hao ran the aura to form a suction force in the palm of his right hand, tried it on the hanging stone stalactite, and soon precipitated a drop of chalcedony, and then under the continuous suction, the chalcedony fell in the process, detached from the water, from milky white to gray, it is a low-grade Bigu Dan.

Picked up the fallen Bigu Dan, just freshly baked, Zhang Hao couldn't help but look at it for a while, it felt very magical, it turned out that this is how Bigu Dan came.

Zhang Hao always thought that Bigu Dan was practiced through an alchemy furnace.

It's just that the process of absorbing stone stalactites to condense Bigu Dan has caused some consumption of aura, which is about one-tenth of the amount of spiritual energy in a week.

And if you have to condense twenty Bigu Dan a day, the amount of spiritual energy consumed is equivalent to the amount of spiritual energy obtained from two weeks of cultivation.

This little spiritual energy consumption is nothing to Zhang Hao, after all, he threw out thirty Zhoutian's spiritual energy with a spirit sword in his hand.

Zhang Hao turned his head to look at Li Ran, this was a lot of pressure on her, she only spit out cultivation for three weeks a day.

The next thing is to be busy with each other, condensing the Bigu Dan one by one......

Condensing Bigu Dan is very easy for Zhang Hao, after all, it is already the seventh layer of Qi training, not the third layer of Qi training and the fourth layer of Qi training. But Zhang Hao still maintained the same speed as Li Ran, and did not hurry to condense.

An hour later, the three of them were busy and began to cultivate to replenish their aura.

After another half an hour, Li Ran ended, and then Zhang Hao also ended.

Zhang Hao didn't go to practice immediately, he wanted to take the opportunity to condense some more Bigu Dan to make reserves for the future.

The three of them and Li Ran were all cultivating in meditation, and Zhang Hao continued to condense.

Zhang Hao didn't try to condense the middle-grade Bigu Dan and the high-grade Bigu Dan, but still condensed the low-grade Bigu Dan one by one and put it directly into his big jade bottle......

Under Zhang Hao's full condensation, he could condense fifty Bigu Dan per hour, so four hours passed......

Until someone finished from cultivation, Zhang Hao always paid attention to their movements, so he hurriedly stopped, pretending to close his eyes and concentrate on cultivation.

Then the others also finished their cultivation one by one, and they all stood up and moved.

"I'll send Bigu Dan to Senior Sister first, and you will stay here. With that, he walked out quickly.

Li Ran asked, "How long are we going to stay here?"

"One year!" someone replied, "I'll go back to Senior Sister in a year to receive the reward!"

Li Ran sighed, condensing the Bigu Dan had greatly delayed her cultivation speed, and she couldn't enter the Gongfa Cave to comprehend.

Zhang Hao got up and looked, he had entered the Baiche Cave in his previous life, and vaguely remembered that this landform was called karst landform, which was due to soluble rocks or something.

"I heard that there is also a sinkhole wonder here, so everyone might as well go and see it. One of them said suddenly.

Idle, the four of them walked to the depths of the cave.

The two of them led the way in front, Zhang Hao and Li Ran followed behind, and slowly felt a stream of air, which became bigger and bigger, and suddenly saw a pillar of light, and under the pillar of light was a bottomless sinkhole.

Zhang Hao looked at the pillar of light, only to see that the rock layer above had collapsed into a huge gap, which was aimed at the sinkhole below.

The other three looked at the sinkhole against the suction of the air current, and the black hole could not see the bottom.

"How deep do you think this sinkhole is?" asked another.

Li Ran shook her head, "It must be very deep, deep!"

"What happens if I fall?" he asked again.

Zhang Hao pulled Li Ran back with a smile, "Then you can only know if you fall yourself! Because if someone else falls, they will definitely not be able to get up, and if they can't get up, they won't be able to tell you." ”

"That makes sense! You don't know what will happen until you fall!" said the other.

Zhang Hao was not curious about how deep the sinkhole was and what would happen if it fell, he just wondered, why did such a strong suction force emanate from the sinkhole?

After looking around the sinkhole for a while, the four of them went back satisfied.

After that, they continued to cultivate.

The next day, Zhang Hao first used the comprehension +1 attribute to comprehend the first part of the Book of Bliss, and then began to condense the Bigu Dan......
