After squatting on the ground for more than half a month, when he returned to the ground, Zhang Ying felt how comfortable the breeze was and how warm the sun was. With such beautiful scenery, why did he squat underground to practice ghost energy? These fellow students really don’t understand the thoughts.

After not seeing each other for more than ten days, Chi Chao has gained weight. The main reason is that there is no high-intensity practice. Chi Chao has become a fat tiger in the past ten days except for eating and sleeping.

Back in his yard, looking at Yiwu Jiuqi who was busy inside and outside, Zhang Ying suddenly called him.

"Yiwujiuqi, you ghost servants can also practice."

Hearing this, Yiwujiuqi's heart was ups and downs. It's been three years! It's been three years! He finally remembered me! Yiwujiuqi suppressed the turbulence in his heart and said with a normal expression: "Yes, ghost servants can also practice, but because ghost servants are not born perfect, they can only practice to the ninth level of Qi training."

Don’t underestimate the Ninth Level of Qi Practice. In the Tiger Ju Temple, the Ninth Level of Qi Practice can be called a master. Because if you go up again, you will be an elder in the Foundation Establishment Stage.

"Well... do you want to practice?" Zhang Ying asked.

Don’t have money to read novels? I’ll give you cash or coins, and I’ll receive them for a limited time of 1 day! Follow the public account [Book Friends Camp] and get them for free!

"Of course!" Yiwu Jiuqi said firmly. He served Zhang Ying conscientiously, and what he wanted was nothing more than that.

"Okay, I'll go and ask," said Zhang Ying.

"Actually, it's not troublesome! You just need to go to the relic academy to transfer me to your command, and then go to the library to exchange for ghost cultivation techniques. This is a must, otherwise even if I learn the techniques secretly, I will be destroyed." Yiwu Jiuqi said quickly.

Zhang Ying looked at him with a smile. Yiwu Jiuqi's heart moved and knew that he was being hasty! How could he help the master make an idea?

"Okay, I'll go tomorrow for your hard work for several years." Zhang Ying said with a smile. Sure enough, whether it is for people or ghosts, it is a great attraction that cannot be ignored.

Although Yiwu Jiuqi is Zhang Ying's exclusive ghost servant, the affair cannot live alone. He relies on the most core magic weapon of Huju Temple - the Tiger Zun Cauldron.

The Tiger Zun Cauldron is the magic weapon of the Jianshe Patriarch. After the ancestor ascended, the treasure stayed in the observation because the hundreds of thousands of ghost servants in the observation were all bound to this magic weapon. The ghost servants do not eat or sleep, but they are not a perpetual motion machine. Their energy supply all comes from the Tiger Zun Cauldron, and the Tiger Zun Cauldron absorbs various "qi" to maintain itself.

If a ghost servant wants to practice, he must first unbind the Tiger Tripod, and then bind it to the Xuanhu to become a real accomplice.

So Zhang Ying had to go to the relic academy to unbundle Yiwujiuqi and the Tiger Zun Cauldron, and then let Chi Chao take Yiwujiuqi as an accomplice. It is equivalent to changing a bound object. If the accomplice is not bound, then he will be absorbed by the underworld or be killed as a wild ghost.

The behavior of removing a ghost servant is not complicated. The senior brother of the relic can operate it alone. The tiger cauldron is placed in the main hall of the relic. When Zhang Ying came, he thought it was a decoration. Now he knows it is a magic weapon for the Golden Elixir cultivation.

This baby is two stories high and several meters in diameter. The three big feet are like pillars. The surface of the baby has various tiger patterns, flying tiger patterns, seat tiger patterns, etc.

After transferring the binding, Yiwu Jiuqi fell into excitement. In the past, binding the Tiger Zun Cauldron was like eating a big pot rice. The Tiger Zun Cauldron would not add food to you. It only maintains the minimum consumption of the ghost servant, and it is enough to be lost. But now it is transferred to Chi Chao, which means that he can fly alone and do it by himself. Whether he eats braised vegetables or is delicious or spicy in the future depends on himself!

The "Dark Ghost Book" that exchanges for the ghost servant's practice requires 30 tests, and Zhang Ying can afford it. When this book was given to Yiwujiuqi, Yiwujiuqi's whole body trembled. If it weren't for the ghost, Zhang Ying suspected that he would cry here.

From today on, Yiwu Jiuqi can absorb ghost energy and practice by himself. He is a ghost, and absorbing ghost energy is an instinct. He was restricted in the past, but now it is open. However, he is also busy, and he has to take care of Zhang Ying and take time to practice. However, as a ghost, he will not be tired, and he can do whatever he wants.

In the evening, when Zhang Ying was practicing, Yiwu Jiuqi could take time to practice. A ghost servant like him had the right to absorb ghost energy underground to practice. Anyway, there were so many ghost energy that it could not be used up.

In this way, Yiwujiuqi has reached the first level of Qi training in a month, which may be the result of being suppressed for too long. With magic power, Yiwujiuqi can practice magic, but Huju Temple has many restrictions on teaching magic, so this matter is not urgent.

The enlightenment pattern can be used again. Zhang Ying clicked it one day and began to realize himself. Since there is a lot of formation knowledge in his mind, the result of enlightenment this time is also related to the formation. Zhang Ying realized a very interesting formation.

"The Netherworld Ghost Silk Refining Formation" is the result of Zhang Ying's knowledge collision and sublimation. It is the product of the combination of formation, silk drawing skills in the Jinyun Cover, and ghost energy knowledge.

When Zhang Ying recalled this formation, he couldn't help but smile. It turned out that the way to enlightenment was so wild!

The purpose of this formation is to extract ghost energy and refine it into something called "Nether Ghost Silk". This thing is similar to Yunxia Silk, but I don't know what it is for. Anyway, it cannot be used as a Jinyun shield, and its nature is different.

So Zhang Ying made a formation plate and handed it to Yiwujiuqi, saying, "This is the formation plate I made. You can automatically arrange it by inputting mana. This formation plate can refine a kind of silk thread. In the future, you will refine it for me when you go to practice."

Yiwu Jiuqi nodded and took it.

The next day, Yiwu Jiuqi brought Zhang Ying a piece of Netherworld Ghost Wire. The thread was dark brown and extremely cold to the touch. I don’t know what it was for. Zhang Ying nodded and said, “Continue to refine it. This short section is useless.”

Yiwu Jiuqi said: "This thread was born from ghost energy. The young master may not be of much use, but I think it is useful to me."

Zhang Ying laughed and scolded, "Okay, you're starting to think about your master's things!" Yiwujiuqi couldn't even shout, and she was so scared that she knelt down. Zhang Ying then restrained her. This kind of joke was not something she had in her previous life, but Yiwujiuqi would take it seriously here.

However, he still remembered Yiwu Jiuqi's words, and this thing seemed to be useful to ghost cultivators.

When the Netherworld Ghost Silk was several feet long, Zhang Ying hung this thing in the relicsyard and placed an order for sale at a "high price" of 20 yuan per meter of Qi Pill.

The maids have a trading function. Zhang Ying doesn't care after submitting the sample. Since he doesn't have time to try the usage of this thing, he will give it to others. There is always a leisurely and painful senior brother who is interested in this kind of thing.

Sure enough, a few days later, the property informed me that someone had bought a 100-meter-long ghost silk.

A few days later, the Netherworld Ghost Silk was instantly bought and bought all of them, leaving a message as much as you want.

Zhang Ying was very excited. Someone had found out how to use this thing! He did not care about the message, but sent Yiwujiuqi to inquire about the news.

This thing was obviously purchased by the same person and has not been circulated among disciples at present. But this is not a problem, so he naturally has his own channels.

A few days later, Yiwu Jiuqi told Zhang Ying about the use of this thing with a resentful look on her face.

"The senior brother who bought the Nether Ghost Silk is a ghost cultivator." Zhang Ying was not surprised by this. Who would be interested in this thing if it wasn't for those people?

"The senior brother thought it was interesting at first, so he tried the usage after buying it. But on the first day he used a usage. Wrap the thread into a rope and tie the ghost servant with this rope. The ghost servant cannot break away. No matter how strong the ghost servant is, it cannot do it!"

Yiwujiuqi paused and said, "The ghost servant who was tested was frightened. He didn't dare to work underground and begged others to change their positions."

Zhang Ying was stunned and said, "Has there been no such thing before?"

Yiwu Jiuqi shook her head and said, "I don't know anything else, but in Huju Temple, only formations, talismans and specific magic weapons are trapped. I have never heard of such a simple rope that can trap ghost servants. This thing doesn't even need to be sacrificed and refined, and it's not even a magic weapon."

Zhang Ying suddenly realized that he was equivalent to finding a new material that could trap ghosts at a lower cost.

‘If this is the case, this Netherworld Ghost Silk has the effect of rejecting ghost energy. Since it can be trapped, can it be defended?’ Thinking of this, Zhang Ying knew why the senior brother was eager to buy Netherworld Ghost Silk. He obviously wanted to try this effect.

The defense of ghost energy has always been a problem. Although there are talismans and formations, magic weapons can do this. However, talismans are consumables and formations are difficult to move. Can magic weapons be used by ordinary monks?

If there are replacements now, this...

Zhang Ying immediately estimated the potential value of the Netherworld Ghost Silk, and he told Yiwu Jiuqi: "Be careful when refining Netherworld Ghost Silk in the future, don't show the clues."

He walked around the house several times, thinking about how to maximize the value of this thing. Although he was a working person in his previous life, he also received a lot of information, and immediately thought of the word "investment".

As the best angel investor, he should be his master, Elder Qu Ji. First of all, he is his master, secondly, he doesn't like this thing, and in the end, Zhang Ying has no choice except him.

The next day, Zhang Ying found Master Elder Qu Ji and handed over the array plate he had made.

"Master, this is a formation I have figured out these days. Please give me a comment." Zhang Ying said that investment should be carried out step by step and you should not be in a hurry.

Qu Ji took the array plate and looked at it. With his cultivation level, he could see the array plate thoroughly.

'What a wonderful idea! This guy has something to do.' Qu Ji thought in his heart, but he said calmly: "The framework of this formation is the Xiaosan Talent Formation, and the core of the spell was transformed by himself. He has a good idea and his idea of ​​Xiaosan Talent Formation is also very unique. You are interested."

He had to admit that he had picked up a treasure. This disciple not only had a slow practice speed, but his understanding of magic and formations was also extraordinary. Although the formation is not complicated at the moment, it is prominent in the word "creative". Condensing the ghost energy into silk threads, this person could think of it.
