After Qin Hao had eaten and drunk enough, his whole person was much more comfortable, and then he promised that he would definitely refine the elixir to improve the cultivation of the three women as soon as possible. But before that, he wanted to see how far Yang Zi's research had progressed.

Alan and the three were fine, so they followed Yang Zi's laboratory. I saw that Yang Zi was already preparing to fuse the twelfth-order demon core with the leather armor of the Starry Sky Beast, this process seemed dangerous, but there was no accident. Because Yang Zi had already communicated with the remnant soul of the Starry Sky Beast, the two sides exchanged conditions, so the leather armor of the Starry Sky Beast was easily cut off, and the subsequent process of fusing the demon core was also extremely smooth.

To Yang Zi's surprise, the twelfth-order demon core given by Qin Hao turned out to be the magic core of another starry sky beast, but I don't know why the will of the starry sky beast in the demon core was forcibly erased, what kind of existence can this be?

With the remnant soul of the eleventh-order starry sky beast residing behind the twelfth-order starry sky beast's magic core, the original remnant soul seemed to understand the advanced method, so its transaction with Yang Zi went smoothly.

The next step is to culture the dark cells, which can only be carried out halfway through the process, and finally the excess dark cells are discarded because there is no suitable memory.

Now that there is a twelfth-order demon core as a memory for dark cells, this makes the storage of energy almost perfect. Yang Zi saw Qin Hao and the four of them coming, and said, "Brother Qin, Sister Lu, Sister Lan, Sister Xiu, you are just here, today I will let you see my great invention!" ”

After speaking, she motioned for the four of them to enter the Purple Dragon spaceship, and then disappeared into dimensional space.

"Brother Qin, you're all optimistic!" Yang Zi shouted: "Collect!" ”

Then with the Purple Dragon spaceship as the center, a violent devouring force spread. I saw that the endless dark energy in the dimensional space was included in the demon core, and within the demon core, as the dark energy was devoured, the dark cells became more and more active, and then continued to divide, then absorb, and then divide, and then absorb, which seemed to be an endless repetitive process.

I don't know how much time has passed, but finally the demon core finally turns off the devouring function. Then Yang Zi took out a crystal from the demon core and said, "Brother Qin, do you know what this is?" ”

Qin Hao took the black crystal, and he seemed to sense that infinite power was about to burst out, but this required a lead. It's like dynamite, if there is a lead, it will explode, and eventually a huge amount of energy will be released.

Qin Hao felt incredible and said, "Yang Zi, what the hell is this?" ”

"This is a magic crystal, or a dark energy crystal!" Yang Zi said seriously, "I guessed before what the final form of light energy and dark energy was? Now I've finally got the promise I wanted. If the final form of light energy is spirit jade, then the final form of dark energy is the dark crystal, but it is called a magic crystal in the demon race! ”

Regarding Yang Zi's explanation, Qin Hao and Alan understood that the so-called righteous demons are only relative, and the dark cells are extracted from the cultivator's body, and through the dark cells, they can absorb the aura of heaven and earth for their own use, which is a relationship between mutual roots and mutual use.

If you abandon the aura of heaven and earth and only absorb dark energy, you will become a demon in the mouth of the righteous path! Whether it is a demonic beast or a demon, the reason why they are stronger than human cultivators under the same cultivation level is already very clear.

In heaven and earth, there is only one kind of dark energy, but there are many forms of light energy, and this invisible differentiation makes spiritual power slightly lower than magic power. Thinking about this question, Qin Hao asked, "Yang Zi, can this dark crystal be obtained infinitely?" ”

Yang Zi nodded and said, "Theoretically, as long as the universe exists, there must be dark energy, and one hundred and eighty percent of it is dark energy, just like nitrogen in the air, other gases only account for a small part." As for why this is happening, I still haven't fully figured it out. ”

Qin Hao smiled: "You don't need to figure it out now, your next task is to collect more dark crystals, and then we can use your spaceship for interstellar travel!" ”

Yang Zi nodded, and left the dimensional space with the help of piloting the Zilong spaceship.

The five of them returned to the City Lord's Mansion and were soon discovered by the Qu Mighty who was hiding in the city.

"Such a strong dark force, what is the City Lord's Mansion doing?" The mighty Qu man was puzzled for a moment, and then disappeared.

When he reappeared, he had already come to the City Lord's Mansion, but after some investigation, he found that it was the dark crystal collected by Yang Zi, and he was immediately surprised. Because if such a powerful energy is detonated, the entire West City will be annihilated.

In order to prevent accidents, and even more so to prevent Qin Hao from being affected, the Qu Great Mighty simply lived directly in the City Lord's Mansion, so that even if the demon core was detonated, he could protect Qin Hao as soon as possible.

Qin Hao returned to his alchemy room, and then transmitted the sound of Qu people to come over to exchange for the Tribulation Pill, Qu people thought they had heard it wrong, so they confirmed it again, and finally learned that Qin Hao was not joking.

One thousand two hundred third-order tribulation pills, this is not a small number, when Yan Yi was ordered to come to Xicheng, and then took the pill in Qin Hao's hand, he happily didn't know how to thank the other party.

I saw Yan Yi take out the refining materials collected by the Qu people for hundreds of millions of years and hand them to Qin Hao, and said, "City Lord Qin, these are all the materials we have collected for hundreds of millions of years, if it is not enough, we can only make it up again!" ”

Qin Hao smiled: "It's okay, I believe that Qu people will be trustworthy!" It's just that I won't be refining the Tribulation Pill for a long time in the future, so don't come here to bother me! I can't refine the Tribulation Pill for you every day, can I? ”

"That's nature! City Lord Qin, you are busy with you, farewell! "Yan Yi took his leave, and now he longed to return to the sun at once, and then tell all the people the good news.

Although the curse of the Qu people has been broken, the Qu people are still indispensable for advancing to the Tribulation Stage, and now there are 1,200 pills, which is enough to cultivate more than a thousand Tribulation masters.

It's just that not all of the Qu people today are masters of the Mahayana period, so these pills are enough for them to worry about it for a million years.

Qin Hao watched Yan Yi leave, and at this time he began to think about how to improve the spiritual power cultivation of the three of Alain, although Alan and Xiuxiu are mermaids, they are still a kind of human beings in nature. As for Lu Chengcheng, not to mention, there was only one way for her to improve her cultivation, and that was to refine the second-order top-grade soul-replenishing pill and the second-order top-grade replenishing yuan pill.

These two pills are not too difficult for Qin Hao, the difficult thing is that the three of them can't just be satisfied with distracting cultivation, so Qin Hao must refine the third-order lower-grade soul replenishing pill and replenishing yuan pill.

It's just that the elixirs required for these elixirs are very demanding, so the cost must be quite a lot. After thinking about it, Qin Hao felt that it was necessary to move the master's medicine garden, after all, Biyou Space was the master's life's work, and he couldn't waste it like this.

Then Qin Hao's voice transmission master, after getting the approval of the Biyou Daoist, he decided to go back to Linhai with Lu Chengcheng.

When Lu Chengcheng heard that Qin Hao was going back to Linhai, she was naturally willing to accompany her, after all, she hadn't gone back for a long time, and she didn't know what happened to her parents and grandfather now.

"Husband, what do you think we should bring back to visit my parents and grandfather?"

"Wife, you decide!"

Lu Tingcheng nodded, and then motioned to Qin Hao to go to the vegetable market first, and buy some delicious food when he saw it, as for the things he weared, he didn't need anything, because Allure's parents and grandfather didn't like the clothes that others bought, and only what they sold themselves was the most suitable.

Qin Hao is now wealthy, as long as Lu Chengcheng casually glanced at it, he immediately offered to buy it, and the shopkeeper said that he was unhappy when he saw such a gold owner, it was fake.

Soon, the husband and wife bought everything they could eat in the market and what was delicious, and they didn't calculate how much money they spent.

After buying it, the couple then went to the portal, then stepped through the portal and disappeared. It's just that what the two didn't expect was that just after they left Ximeng City, suddenly a person with a hat also left.

Qin Hao and his wife naturally didn't find anyone following, and they went straight to Linhai City. Before coming to the big villa of the Lu family, there is not much change here from before, if you really want to say that the change is naturally that the security personnel have changed batch after batch. At this time, this group of security guards didn't know Lu Tingcheng and his wife at all, and at this moment, the big housekeeper walked out, and after he saw Lu Tingcheng, he said happily: "It's the eldest lady and uncle, why are you free to come back?" ”

Lu Chengcheng said: "Uncle Qian, Qin Hao and I came back to see my parents and grandfather, are they at home?" ”

The big housekeeper said: "Miss, your parents are traveling, and the old man is at home!" Come in. ”

After speaking, Qian Bo took the husband and wife to the living room, and the old man quickly walked out. It's just that he seems to be a little old, and his mental state is not good.

"Hao'er and Allure are back! It's good to come back, a little money, and make tea for their husband and wife. Lu Jiahao signaled.

Then he looked at the two of them and said enviously: "It's better for you to step into the door of cultivation, after so many years, you are still so young, unlike me!" ”

Seeing that his grandfather was a little old, Lu Chengcheng's heart tightened, and then said: "Grandpa, you don't have to be sad, as long as you want, we can help you." Also, this time we came back and brought you and your parents a lot of delicious food, so you don't have to cook! ”

After speaking, Lu Chengcheng motioned for Qin Hao to take out the food, Qin Hao waved his hand, and the table was suddenly full of good wine and food. Although most of the old men have seen it, they have not necessarily eaten it, and even if they have eaten it, the taste may not be the same.

Qin Hao said: "Grandpa Lu, this is a spirit fish, not only delicious, but also stimulates the potential in the body, do you want to taste it!" ”

Lu Jiahao did not refuse, took the spirit fish and tasted it, it was delicious and tender, and it was really the best among the fish. He couldn't help but take a few more bites, and suddenly coughed violently.

Qin Hao asked puzzledly, "Grandpa Lu, what's wrong with you?" ”

The old man said: "I have caught a cold recently, so I can't eat more of this delicious fish." ”

Qin Hao nodded, and then motioned to Qian Bo to remove the fish, and then distribute it to the others to eat. Then he tore off a big leg of lamb for the old man and said, "Grandpa, try this, I heard it tastes good!" ”

The old man took the leg of mutton, and then tasted a few bites, the taste is indeed very different, although it is the same roasted whole sheep, but the roasted whole sheep of Ximeng is more fragrant, and the meat is firmer.

Obviously, the quality of the meat of these sheep has changed since they were brought to the Western Union. Next, the old man tasted roast beef and roast chicken, and the taste was different, which was why Qin Hao bought a little bit of everything.

After all, the old man was old, and he didn't eat much, so he asked Qian Bo to take the meat away and distribute it to others. This can be regarded as a cheap person, but Qin Hao and Lu Chengcheng didn't say much.

Then Qin Hao took out a Longevity Pill and said: "Grandpa, you must accept this Longevity Pill, we will rarely come back, if you want us, you can go directly to Ximeng to find us!" ”

The old man accepted the pill and asked, "Are you planning to leave?" ”

Qin Hao nodded and said, "This time we will go back to Linhai to do some business, the time is a little urgent, so we have to leave now!" ”

The old man sighed, and then watched the couple leave.

Just after Qin Hao and Lu Chengcheng left, suddenly a man in black came to the Lu family's villa. In order to avoid unnecessary trouble, the man in black entered the villa incognito, which made the security guard not notice it in the slightest.
