Many people from the group who saw Qi Zhiheng came up to greet him, but Qi Zhiheng could not remember most of them. However, he did remember some of the people next to them. Presumably, these familiar people were there when he rescued the people.

Qi Zhiheng talked with them for a while, and finally the leader of the Yuansheng Academy invited the Qi family to take the flying treasure tower back together.

After returning to the Qi family in the capital city, Qi Zhiheng merged the fragments of the Boundary Stone in his hand together, leaving only a small gap in the entire Boundary Stone.

Qi Zhiheng asked the moon beast, "Are so many guide stones enough?"

The Moon Beast said, "In terms of volume, it is enough, but this guide stone is a used guide stone. It can only be used on the original spatial channel. And that spatial channel has already merged with the laws of this guide stone. The two have formed a memory, so it must be complete."

Qi Zhiheng had a headache and turned to leave the space.

Currently, several members of the Qi family have already entered the late stage of Foundation Establishment, and they are almost all suppressing their cultivation. Qi Zhiheng needs to use medicinal baths and pills for the next stage, but he has no clue about the spiritual herbs in them. He has never heard of them on the Xuanling Continent. He can only hope that he can find these spiritual herbs in the cultivation world.

After Qi Zhiheng went outside, everyone began to discuss what they had gained in the secret realm, and to see if there was anything that other family members needed. After exchanging gifts, Qi Zhiheng brought up the issue of fire seeds.

“I have sealed many fire seeds in my space. The quality of these fire seeds may be average. Only the mother fire is of the best quality. However, the quality of the mother fire is too good. If any of us fuse with it, it may be very dangerous. Therefore, I do not recommend fusing with the mother fire,” Qi Zhiheng said.

Speaking of the fire seed, Gu Qinglin had the authority to speak: "I fused with a fire seed in the secret realm. I don't know the specific quality, but after fusing it, my cultivation level rose by three levels, and I entered the peak of the Foundation Establishment stage."

Qi Zhiheng nodded: "Then, if you are at the point of breaking through to the Golden Core stage, you should not fuse the Fire Seed for the time being, so as not to form a false core after the breakthrough."

Hearing about the fake core, Qi Wantian felt a pang of sadness. He was the only one restricted here. It was said that it was difficult for cultivators who had formed a fake core to convert it into a golden core, and he, who should have been the most powerful in the family, had suddenly become the worst at forming a golden core.

"Since the two types of sub-fires are of the same origin, can they be fused?" Qi Zhenhe also belongs to the category of those that cannot be fused. He has already entered the late stage of Foundation Establishment for some time. If he were to fuse the fire seeds, he would probably advance to the Golden Core stage.

Qi Zhiheng already had some understanding of this: "Sub-fires cannot merge on their own, but they can devour each other. However, this devouring is based on the premise that they are not of the same origin. Fires of the same origin will generally not kill each other when they sense each other's aura. However, it is a different story for fires with intelligence, such as the mother fire. Once it has subjective thoughts, it may control itself to devour the sub-fires."

"If it can devour anything as long as it's consciously manipulated, then a contracted sub-fire, under the master's control, can also devour other fire seeds?" Gu Qinglin asked.

Qi Zhiheng responded to his guess: "That's right, fire seeds can devour each other to advance. As long as the owner of the fire seed has this intention, even fire seeds of the same origin will devour each other."

This means that in the later stages, one can rely on gradually consuming other fire seeds to strengthen one's own fire seed. This way, one will not be overwhelmed by the prospect of not being able to consume it all at once, and one can slowly improve the quality of one's own fire seed.

Therefore, Qi Zhiheng does not intend to sell these embers; he wants to keep them for himself and his family.

Finally, Qi Zhiheng, Yang Yitian, Qiu Yuerong, Qi Zhenhao, and Qi Zhenhua are the ones who plan to merge the flames.

Qi Zhiheng led the group into the space, where fusion was much easier because Qi Zhiheng could consciously control the entire space.

With the restrictions imposed by the talisman, and the Qi family using the incantation for fusing the fire seed, the danger of everyone fusing together became almost zero.

Each of them underwent fusion, and their cultivation levels improved significantly.

Qiu Yuerong, Qi Zhenhao, and Qi Zhenhua directly entered the peak of Foundation Establishment, while Yang Yitian entered the middle stage of Foundation Establishment.

But Qi Zhiheng's situation is a bit of a disaster!

While others could at least improve their cultivation by three or four levels, he only improved by one level! His strength, which was originally around the second level of Foundation Establishment, has now been raised to the third level of Foundation Establishment.

There's no way around it; his cultivation can only progress when the spiritual energy he cultivates reaches saturation. Since his spiritual energy is currently unevenly distributed, his cultivation can only proceed slowly.

Although the spiritual energy in the fire seed could be transformed and absorbed, he did not transform and use it. He was too reluctant to directly transform such pure fire-attribute spiritual energy into attribute-less spiritual energy.

Perhaps he could collect all ten types of spiritual treasures that aid in cultivation, and use them together when he needs to break through.

The karmic burdens of a remnant soul are the source of dark-attribute spiritual energy.

Blazing Sun Sand is a source of light-attribute spiritual energy.

When combined with the fire seed, it becomes fire-attribute spiritual energy.

In addition, he also needs to collect items with other attributes.

The dark attribute spiritual power transformed from karmic obstacles will eventually run out, and he has already absorbed most of it.

Sunfire Sand can be continuously produced through Sunfire Source, but its effect is somewhat limited.

Some spiritual energy remained after fusing with the fire seed, but that was only for that one time. However, he had many fire seeds, so he could just use his own fire seeds to devour other fire seeds.

Yang Yitian, however, did not have as many concerns. After fusing with one fire seed, he devoured another, directly raising his cultivation to the mid-Foundation Establishment stage, surpassing Qi Zhiheng.

Qi Zhiheng: "..."

I don't know why I ended up being the one with the lowest cultivation level in the whole family...

In order to find a spiritual object that could improve his cultivation, Qi Zhiheng decided to visit the Yuansheng Academy.

Those insiders probably have a lot of stock, but they don't usually release it.

Qi Zhiheng found Sheng Mingyue.

Upon seeing Qi Zhiheng, Sheng Mingyue couldn't help but tease him, "Isn't this the Qi Zhiheng who doesn't forget to earn spirit stones even when he's on the run? What? You know I have spirit stones and want to try and earn some?"

Qi Zhiheng said helplessly, "Senior Brother Mingyue, can we let this matter drop?"

Sheng Mingyue laughed and said, "I was going to let this go, but aren't there quite a few people in the Yuansheng Academy discussing it? They haven't stopped yet."

Qi Zhiheng had indeed heard a lot of people pointing fingers and gossiping along the way. He had already made quite a name for himself selling pills before, and this time he saved many people in the secret realm. His popularity had not yet subsided.

Sheng Mingyue got down to business, saying, "What brings you here today?"

Qi Zhiheng explained his purpose: he wanted spiritual items of various attributes that would greatly benefit his cultivation. Sheng Mingyue, on the other hand, had become a formal disciple of the Yuansheng Academy, unlike them who were merely apprentices. They had fewer opportunities to come into contact with spiritual cultivators of higher cultivation levels.

Qi Zhiheng's business originated from exchanging elixirs for spiritual items. If you need any particular elixirs, you can contact him after confirming the price.

Qi Zhiheng added, "I don't have any spirit stones!" Although he had earned a lot of spirit stones in the Tianheng Secret Realm, with the space around him, no matter how many he earned, it wouldn't be enough. He had spent a lot of spirit stones to ensure that the spirit herbs he planted inside could grow smoothly.

These spiritual herbs were all harvested during this trip to the secret realm. Transplanting spiritual herbs has a certain failure rate, but fortunately, his spatial environment is quite good. As long as he can provide enough spiritual stones, the growth rate of these spiritual herbs can be improved, and their quality will also be relatively better.

Every time Qi Zhiheng saw spirit stones flowing away, he wanted to dig up a few more spirit veins to bring back!

But spiritual veins are not so easy to find, so he could only think about it in his mind.

Sheng Mingyue said, "You can rest assured, I will convey your request, and I believe many people will be willing to give you face."

"I never expected to have such influence," Qi Zhiheng said with a shake of his head and a smile.

After leaving some of the items he had obtained from the secret realm with Sheng Mingyue, Qi Zhiheng took his leave.

Thanks to Sheng Mingyue's promotion, many people came with spiritual treasures to ask for pills. The Qi family's pills are very famous, and now that they can specify which pills to refine, many people have come to them.

Qi Zhiheng also obtained a lot of spiritual items as a result.

After obtaining the spiritual item, Qi Zhiheng immediately went into seclusion. When he emerged, his cultivation had reached the mid-Foundation Establishment stage.

Qi Zhiheng went into seclusion for more than a month. After his breakthrough, he returned to the Qi family.

Yan Yu, who had previously mentioned visiting the Qi family in the secret realm, came to visit Qi Zhiheng just two days after he emerged from seclusion.

The group was fairly familiar with each other, and the Qi family seemed to have a good impression of Yan Yu, but the Qin Nianzhu incident left them somewhat uncertain.

Yan Yu came to visit and brought some gifts, and then he went back.

After Yan Yu left, Yang Yao and the others even began to suspect that Yan Yu was still unaware that Qin Nianzhu had been killed by their family.

Qi Zhiheng said, "Perhaps there's more to it than meets the eye. Since Qin Nianzhu could use a love potion on my uncle, maybe she could use it on Yan Yu too? If Qin Nianzhu dies, wouldn't the other party be normal?"

Qi Zhenhe said, "But didn't you say that after Qin Nianzhu died, the person on the other side of the love potion might die? I see Yan Yu is alive and well."

“Didn’t we already deal with the love potion? And it might not even be a love potion, it could be something else.” Qi Zhiheng sat down, took a sip of tea, and looked at Qi Zhenhao, saying, “And Uncle, how can you be so sure that Yan Yu likes Qin Nianzhu?”

Qi Zhenhao thought for a moment and said, "Qin Nianzhu said it."

Qi Zhiheng was speechless. He felt that Yan Yu was much more interested in Qi Zhenhao than in Qin Nianzhu. Maybe his uncle, being such a simpleton, had just made a misunderstanding.

He put down his teacup: "Whatever Qin Nianzhu says goes. Why don't you believe me when I say that our ancestor is still a Mahayana stage ancestor?"
