The night in the back mountain gradually became hazy, and a fog appeared.

Originally, the vision was not clear, but now it is good, and the trees in front of me are basically invisible.

The dragon dust was also bored, and threw the stone into the woods.

This stone seemed to stir up a tide, and countless small green eyes appeared.

"Senior brother, the hole in the ground has been dug for you to enter. Ye Yu approached the dragon dust and whispered.

When Longchen heard this, he was also happy, threw the remaining stones towards the pool, and immediately ran to the hole.

In the cave in the ground, Tian Yuan made the last layer of moisture protection, and he used wooden planks to lay out the two ear chambers before he walked out.

"Wow, Master, you can live in this cave. Longchen walked into the cave and said.

"One is left for you to alchemy, and the other is for Xue Yan, Ye Yu, you can come here with me. Tian Yuan said.

"Yes, Master. Ye Yu immediately agreed.

Xue Yan also walked out of her ear chamber, although it was simple, but it was good to have such a place in the mountains.

Tian Yuan saw that the three of them had arrived, and with a wave of his right hand, three giant spirit stones appeared in front of the three of them.

Xue Yan and the three of them were completely dumbfounded, they had never seen such a big spirit stone.

Can this be considered a spirit stone? How do you feel that it is full of liquid?

"Master, what kind of spirit stone are you?" Ye Yu asked in shock.

"Actually, I don't know very well, it seems to be called Super Rhyme Spirit Stone. One piece for each of the three of you!" Tian Yuan said.

"Haha, thank you, Master," Longchen said, and was about to pick up the spirit stone.

Tian Yuan hit a "popping chestnut", and then looked at Xue Yan and Ye Yu.

The three of them didn't understand what Master Shi meant.

"I haven't finished my sentence yet, so what's the hurry? Tian Yuan said.

"Oh, Master, you say, let's listen. Ye Yu said.

"I'll give you a task, Xue Yan, you step into the Jindan period as quickly as possible, and Ye Yu, you also have to step into the Jindan period, as for the dragon dust, you just need to step into the foundation building period as soon as possible." If this spirit stone resource is about to run out, let me know quickly, because there is not much time left for you. Tian Yuan said with a sense of crisis.

After hearing this, the three of Xue Yan were also stunned, is it really dangerous inside?

"Master, can't we stay here forever? No one will come here anyway. Ye Yu said.

Xue Yan and Long Chen also nodded at the same time, although they said that they would go to the back mountain, but they didn't say how to go to patrol the mountain, anyway, they were hiding here for a month and going back.

"No, as a disciple of the Heavenly Dao Sect, you must have a beginning and an end to do things, you guys hurry up, I don't want you to die in the hands of demon beasts. After Tian Yuan finished speaking, he walked out of the cave directly.

Now he is completely fighting wits and courage with his apprentices, and if the apprentices don't complete the task, he doesn't want to get a better reward.

As for death, he can only hehe, anyway, he doesn't want to die, just scare them.

Xue Yan and the three of them looked at Shizun's serious expression and the back of the leaving, and the three of them looked at each other.

"Master Venerable is right, since we are disciples of the Heavenly Dao Sect, let's show that we dare to be, Ye Yu, especially you, your task is the heaviest, not only to break through the foundation, but also to step into the Golden Pill. Xue Yan said.

"Don't worry, I just don't want to cultivate, now that I have this big spirit stone, I can build a foundation tonight. On the contrary, it is the second senior brother, and his cultivation is the slowest to improve. Ye Yu said indifferently.

Longchen also understands that indeed, in front of his senior sister and junior brother, his cultivation speed is indeed the slowest.

"Senior brother, don't refine the pill this time, you will use all your spiritual energy for cultivation. Xue Yan said.

"Well, I'll try my best. Longchen nodded.

"Okay, let's cultivate separately, hurry up, we will definitely be able to do it. Xue Yan said.

Long Chen and Ye Yu nodded, they understood that the test they were being had just begun.

Tian Yuan withdrew his senses, a happy smile appeared on his face, he sat on the dirt slope and glanced at the moonlight, he always had a bad feeling.

Forget it, let's work early, as long as the trap is good, at least the small monster beast can't get in.

Tian Yuan looked at the piles of soil, and also took out the bucket and walked towards the pool.

He prepared a clod wall, with this thing, not only to prevent moisture, but also to block the leakage of breath, and then to make a large vent.

He is now taking one step and thinking about three steps. If you can't dig a cave in the mountain stream, you can also build a simple cliff house.

Tian Yuan transported water again and again, made the excavated soil into a square shape, and then fixed the four sides with wooden planks.

If you don't know, you think that the mason is going to build a house.

The night passed quickly, and Tian Yuan also sat on the sidelines, waiting for the dirt to dry.

Suddenly, thunderclouds rolled in the sky, as if it was going to rain.

I'm going to play with me when it's raining!

Just as Tian Yuan was thinking this, the aura in the cave instantly skyrocketed.

Tian Yuan's first thought was the Thunder Tribulation! It's broken, it is estimated that Ye Yu has broken through the foundation.

Tian Yuan didn't even think about it, and ran towards the cave in the ground.

At this time, Ye Yu was still holding the giant spirit stone, and his expression was extremely happy.

"I'll go, my little ancestor, you're going to cross the catastrophe, and you're still holding it!" Tian Yuan said, directly pulling up Ye Yu and running out.

Ye Yu is also confused, and Zhuji is also going to cross the catastrophe?

And before he could react, he had already been pulled outside by Tian Yuan.

Above the sky, the thunderclouds were still condensing, and Tian Yuan didn't care about it, pulled Ye Yu to the edge of the pool, explained a few words, and he left quickly.

Ye Yu's face was confused, he hadn't experienced it at all.

The "booming" thunderclouds continued to compress, as if they were going to destroy Ye Yu.

"Master Master, if I die, you remember to help me take care of Senior Sister!" Ye Yu shouted loudly.

"Don't worry, you can't die, remember my words, hurry up and stop it!" Tian Yuan shouted as he stood on the dirt slope.

After Ye Yu heard this, he hurriedly lucked his aura and released layers of aura shields outside his body.

Tian Yuan was a little frightened when he saw that the thunderclouds on the sky dome were still condensing.

He had never seen such a terrifying thunder tribulation, how could this thunder tribulation be more fierce than the Dan tribulation?

And Tian Yuan didn't notice that in the woods now, where were there still demon beasts, and countless abyssal insects were rapidly approaching Ye Yu.

"Booming" thunder, flashing with purple lightning.

"Click", a purple thunderbolt, followed the trend. Straight towards Ye Yu, as if he wanted to kill him.

"Boom~!"

The entire pool exploded in an instant, and Ye Yu was also shocked, he glanced around and found that he was actually fine!

Even if the aura shield is not broken, is it crooked?

"Haha, Master Master, this thunder is crooked!" Ye Yu said happily.

Tian Yuan was also stunned, no, how could this thunder tribulation be crooked?

Tian Yuan immediately looked at Tianqiong, found that there was no problem, and looked at Ye Yu again, and this look almost scared him!
