After Li Ye left, Nie Tian carefully digested the information he revealed about the cracked airspace and started his own practice.

A night passed by.

In the early morning, when the sky was dawn, Nie Tian looked at the two shattered spirit stones in his hand and remained silent.

In the middle of the night, he consumed two spirit stones and used the spiritual energy in the spirit stone to refine the Dantian Spirit Sea little by little.

After breaking through to the late stage of the acquired realm, his Dantian Spirit Sea can expand again and recondensate the spiritual energy in the Dantian Spirit Sea.

This process may take a long period of accumulation to expand the spiritual sea to its limit and clean and refine the spiritual energy over and over again.

In the end, he may be able to reach the bottleneck of breaking through the Zhongtian realm and make a smooth breakthrough through the perception of his state of mind.

Perhaps the reason for saying it is because in his Dantian Spirit Sea, in addition to the three spiritual vortexes, there is also a star vortex, a flame vortex, and a grass vortex.

These three vortexes with different attributes also need to guide the power of stars, fire spirit power and wood spirit power with different attributes.

In his feelings, because he has practiced three additional spiritual techniques, if he wants to successfully enter the acquired realm, he must also refine and understand the three attribute spiritual techniques.

This means that the time it takes for him to break through the acquired realm is much slower than that of those who only have one attribute.

Since the Destroyed City has no spiritual energy to borrow, his cultivation can only pass through spirit stones. In the middle of the night, his cultivation consumed two spirit stones. If he practiced throughout the day, he might need eight spirit stones.

But there were only more than 300 spirit stones in his storage bracelet. At this speed, his spirit stones were only enough for more than a month.

The token given to him by Hua Mu only has a three-month period. After three months, the token deadline will arrive.

At that time, he had to continue the time with the spirit stone to the Blood Skeleton.

"Spirit stones are far from enough." Nie Tian secretly had a headache.

"Are you awake?" Li Ye didn't knock on the door and pushed it in directly. After walking into the stone chamber, he threw down a piece of blue-black wood from the storage ring and said to Nie Tian carelessly: "From today, you will be responsible for doing things for me. I will give you the corresponding spirit stones according to your efforts."

Nie Tian, ​​who was worried that there were not enough spirit stones, suddenly lit up and he said excitedly: "How to do it?"

“It’s very simple.”

Li Ye threw a dagger to him, took out a square piece of wood, and cut a piece of blue-black wood into the shape of a wood chip in front of Nie Tian.

"This is Heiyin Wood, an intermediate third-grade spiritual material, which can be used to build a formation. If you cut this piece of Heiyin Wood into a hundred pieces of wood that are large in this wood, you can exchange me for a spirit stone."

"As long as you don't waste too much, it's enough to cut out 150 pieces of wood like this. If you don't waste too much, you'll waste my materials and I won't give you a piece of spirit stone!"

"Also, this dagger is for you for the time being

If you use it, you will have to return it to me in the future.”

After Li Ye explained, he threw the dagger to Nie Tian and signaled Nie Tian to operate.

As soon as Nie Tian grabbed the dagger, he felt that the entrance was quite heavy and showed a cold feeling.

He immediately realized that this dagger was probably of a level not low, and it was definitely an extraordinary item.

Holding the dagger, he took a piece of Heiyin Wood, and he placed the finished piece of wood underneath, and began to carefully cut Heiyin Wood according to Li Ye's method.

When the dagger was pressed down, he used five points of force, and the black wood only cracked a gap and was not cut off in one go.

"Huh!"

Nie Tian shouted lightly, and couldn't help but increase the force. He used a lot of force before cutting off a piece of black wood with a "crack".

"This black wood is hard, better than many solid stones." Nie Tian was secretly frightened after cutting a piece of it, and then continued to cut other corners in front of Li Ye in the shape of the wood chip.

It took him half an hour to cut it into a piece of wood of the same size under Li Ye's gaze.

During this process, Li Ye just stared at him without saying a word.

After he finished a piece of wood, Li Ye said, "You guy, you have a lot of brute force."

"What's wrong?" Nie Tian looked up.

"It's nothing." Li Ye touched his nose and muttered: "Generally, those who have the acquired realm of cultivation need to use the spiritual power in their bodies to cut the black Yin Wood. Only by calling the spiritual power to support the dagger can they cut off the black Yin Wood. If you don't use a trace of spiritual power, just relying on hand strength, you will cut the black Yin Wood, which means you are very strong."

"So that's the case." Nie Tian smiled, "I'm really stronger."

"It's nothing strange." Li Ye curled his lips, too lazy to pay attention to him, and said, "I'll leave first, I'll come again before dark. Let's see your results at that time."

"Oh." Nie Tian nodded.

As soon as Li Ye left, Nie Tian focused on cutting black wood into wood chips of the same specifications to earn the spirit stones he was in urgent need.

A piece of black wood turned into more than a dozen pieces of wood under his careful cutting.

"Gurl!"

He was concentrating on doing things, and suddenly heard the sound of hunger and thirst from his stomach. He took out some spiritual beast meat from the storage bracelet and teared it.

After looking out the window, he found that it was already evening without realizing it.

The cutting of more than a dozen pieces of wood chips actually took him half a day, which made him suddenly feel a little depressed.

Shaking his head, he quickly accelerated his progress and continued to cut the wood chips in exchange for the spiritual stones for cultivation.

Before dark, Li Ye arrived as scheduled, glanced at the wood chips made by Nie Tian, ​​counted them, and said, "It's exactly twenty. It's agreed that one hundred yuan can be exchanged for a spirit stone. You can continue to work hard later."

He took away the twenty pieces of wood, ignored Nie Tian, ​​and left with a shaking head.

Nie Tian looked helpless

He stopped practicing that night and devoted all his energy to cutting those wood chips.

Two days later.

Exhausted Nie Tian finally collected a hundred pieces of wood and exchanged a spirit stone from Li Ye.

"You can't do this." Li Ye said drunk, "You are too slow, and you just earn spirit stones and give up your own cultivation. If I were you, I would do things during the day and practice with all my heart at night."

"The spirit stones I earn are far from the speed of consumption." Nie Tian said angrily.

"That's your business." Li Ye laughed and said, "Who made you incompetent and don't know how to refine weapons. You can only do the simplest thing that can't earn too many spirit stones." After mocking Nie Tian for a few words, he left in a good mood.

In the next half month, Nie Tian guessed that Li Ye was deliberately targeting him, and did not earn too eagerly. Instead, according to Li Ye's statement, he cut the black wood during the day to earn spirit stones, and at night he used the spirit stones he had hidden to practice seriously.

In half a month, he exchanged five more spirit stones from Li Ye.

But the spirit stones he consumed were about fifty, which resulted in the number of spirit stones in his storage bracelet being only about two hundred and eighty.

At night, he also tried to guide the light of the stars through the Star Break and incorporate it into the star vortex in the spiritual sea.

Unfortunately, through the light curtain of the Destroyed City, he could clearly see shining stars, but because of the existence of the light curtain, he could not condense the light of the stars from the stars in the void, and even the vortex of the stars could not be refined and operated.

Later, due to the shortage of spirit stones, he had to use the few remaining fire crystal stones to practice the Flame Spirit Art and increase the power of the flame in the flame vortex.

During this period, he almost never went out, and he had never seen Pei Qiqi's shadow.

On this day, Li Ye arrived again, put away another hundred pieces of wood chips, threw them to Nie Tian a spirit stone, and suddenly said, "Do you think you've made too little?"

"Yes." Nie Tiandao.

"Do you want to get rich?" Li Ye's eyes flashed.

"What's the way?" Nie Tian was excited.

"I think you are quite honest, so I will give you a chance. As long as you are honest and obedient, I guarantee that the spirit stones you earn will exceed the sum of these half a month!" Li Ye said insensation.

"Let me tell me." Nie Tiandao.

"You are very powerful and useful to me. If you go to the Huankong Mountains with me, I want to get something out." Li Ye said.

"Leave the Destroyed City and go to the Huankong Mountains?" Nie Tian's face changed.

"Don't be nervous, I have my way. Of course we are not hiking. We can borrow the space teleportation array of the Destroyed City to go directly to the Huankong Mountains to avoid the garbage wandering outside the city." Li Ye smiled, "Senior Sister Pei will go too. She built a small teleportation array in the Huankong Mountains, which allows us to enter and exit the Damnkong City and the Huankong Mountains."

"good!"
