Their third experiment had two purposes: first, to corroborate the conclusion that the yin and yang qi would be transformed when perceived, and second, to test how long it would take for the yin and yang qi to be produced again.

This time, after changing Qianxue to depict the formation flag, after planting the formation flag, Jin Yang first sensed the area surrounded by the formation flag, and wiped out all the yin and yang qi in the area, and the formation naturally could not run.

But Qianxue was still a little worried, and said, "Senior Jin, if the formation is running, what if there are people in the space over there?"

Jin Yang said with a smile: "Little friend, don't worry, we have done two experiments before, even if there are people over there, they will never dare to stay in that space." ”

Qian Xue thought about it, so she opened the formation after Jin Yang perceived it.

The moment the formation was running, the formation flag did not crack, and their guess was indeed correct! The next thing was to wait for the formation flag to crack, and the moment the formation flag broke was the time when the yin and yang qi was born again.

An hour passed, and the flag remained motionless.

......

A day later, Jin Yang said to Qianxue: "Why don't you go and read the jade slips in the Tibetan Scripture Pavilion by yourself, don't miss it when you come in, there is an old man staring at it." ”

Qian Xue shook her head and said, "The junior entered the Scripture Pavilion just to find the Spirit Absorbing Array, since it is not in the Scripture Pavilion, the junior does not plan to stay in the Scripture Pavilion for a long time." ”

Jin Yang thought for a moment and said: "Actually, it is very simple to design a formation with the same effect as the Spirit Absorbing Array, as long as Xiaoyou can find a material that can absorb energy, why is it difficult to design such a formation?"

Qianxue remembered the cold stone, took it out and handed it to Jin Yang, and said, "Senior Jin, is this material feasible?"

Jin Yang sensed the moment and said with a smile: "Excellent! I will design a formation for Xiaoyou." ”

Qianxue was grateful, and then she deeply realized that if you want to be proficient in the formation, it is not enough to be familiar with the principles of the formation, but also have some understanding of other knowledge, so as to bypass the class.

Seeing that Jin Yang was staring here, he was idle, so he decided to go to the floor where the jade slips related to the materials were stored to have a look.

She picked out a jade slip with "material structure" written on it and looked at it.

All things are made up of the harmony of the five elements, and different structures form different substances.

At present, monks can only perceive the seven-layer structure of matter, each of which is extremely complex, and the distribution of light points within it is so complex that it is difficult to study thoroughly.

Some of the known properties: the distribution of light spots in one layer determines the morphology of matter, and the distribution of light spots in higher levels determines the distribution of light spots in lower layers.

That is to say, as long as the position of the light point on the second layer is slightly changed, the light point of the entire first layer will change, and if you are not careful, the material will collapse.

The higher the level, the more difficult it is to change, and the more difficult it is to move more than three layers.

If the second layer of light is forcibly pulled into the first layer, the matter will emit great energy, and this is one of the basic principles of the powerful magic of the monks in the foundation building period.

It's just that in terms of how to pull and which to pull, different monks have different understandings, and there is a difference between strength and weakness.

She was tirelessly reading the jade slip when she suddenly heard a secret voice coming into her ears: "Little friend, come here." ”

She hurriedly put down the jade slip in her hand and returned to the eleventh layer.

At this time, the array flag had been broken, and seven days had passed, which meant that the original place had once again generated yin and yang qi, although it was not known whether this yin and yang qi came out of nothing, or if it came from other places.

But Jin Yang's expression was a little strange, isn't this test quite conjecture?

Without waiting for her to ask, Jin Yang said, "We were wrong again!"

"What's wrong?"

"Just now, at the moment when the formation was activated, I accidentally pushed your cold stone into the formation, and as a result, the cold stone disappeared!"

"In other words, this formation will not only teleport things from other spaces, but also things from this space?"

"Yes, this should be a spatial exchange formation. ”

Qianxue was incredulous when she heard it, she really didn't know which monk created the formation, his formation attainment could really be described as a creation that conquered the heavens and the earth.

Her heart suddenly moved, and she said: "Senior Jin, since this formation is an exchange space, why don't we let someone teleport over, so that we can know where it is, how far away it is from here, and why this formation is located there." Knowing this, can't you decipher the meaning of that formation pattern?"

Once the meaning of the pattern is deciphered, why is it difficult to design a similar formation by yourself?

Jin Yang also dared to be interested, if he could know the true meaning, he would die that night, and he would have no regrets for the rest of his life.

It's just that it's really dangerous to go here, and a few days ago there was a broken palm from there, what if that person holds a grudge and ambushes there for seven days and seven nights in a row?

He was worried in his heart, it stands to reason that his cultivation is higher than hers, and he should go, but he really doesn't want to go outside the Scripture Pavilion.

He was pondering the pros and cons when he overheard Qianxue say, "I'll go." ”

He hurriedly said: "Or I'll go, your cultivation is low, in case of danger, how can you escape?"

Qianxue smiled: "This formation can only be activated by me, how can you come back?"

Jin Yang sneered and said, "Yes, yes, but I'm confused." ”

Qianxue is not in a hurry to go, since she knows that there is danger, she has to be prepared, at least she has to buy dozens of array flags first, otherwise she will not be able to come back.

Three days later, she came to the twenty-third floor again, bought the fifty array flags she had ordered, thought for a moment and asked, "What do you have here to defend yourself?"

The nun in front of the counter smiled, "What do you need?"

Qianxue had really never used a talisman seal, and asked, "What is the effect of the talisman seal?"

The female cultivator knew that the girl in front of her was wealthy, so she said patiently: "The monk engraves the spell on the rune paper to form a rune seal, although this kind of rune seal is not very powerful, but fortunately, it does not have to consume its own mana at all when using it, and it does not have to spend time to pinch the trick, and sometimes it can also have unexpected effects." ”

Qianxue asked, "What are the talismans and how much are they worth?"

"I have all the five elements of the talisman here, all of which are spells that can only be performed by monks in the foundation building period, and they are extremely powerful. A hundred medium-grade spirit stones. ”

Qianxue was startled: "Why is it so expensive?"

"The more powerful the rune seal, the higher the rune paper, and the lower the chance of successful carving, naturally more spirit stones. ”

For her own safety, Qianxue bought more than a hundred, and she silently counted her stock of spirit stones: eleven top-grade spirit stones, more than 100 high-grade spirit stones, and thousands of lower-grade spirit stones.

I felt a lot more relieved.

Before teleporting, Jin Yang handed her two jade slips, one was a spirit absorption array designed by him and needed a cold stone as a guide, and the other was a jade slip that he asked her to hand over to the descendants of the Jin family.

Formation activated!

Jin Yang watched Qianxue disappear into the air, and sighed with emotion, this girl is above him regardless of heart or courage, I just hope she can be safe.

A year later, he was still looking forward to it in the Scripture Pavilion, staring at the empty space on the table every day, hoping that one day that pretty figure would suddenly appear there.

It wasn't until ten years later that he finally gave up his thoughts and died in loneliness, sleeping with infinite sorrow.
