I will return you 10,000 times my money. I am the strongest furnace in the Demon Sect.

Liu Yao had such an awareness, and of course Zhao Mu showed his sincerity immediately.

Hearing Zhao Mu's promise, Liu Yao felt happy, and a blush quickly rose on her face.

Liu Xi on the side became silly and happy.

Although the matter of revenge has not yet been revealed, with Zhao Mu joining the team, there is finally some hope.

She was also looking forward to it. It would be perfect if she could give birth to a child with the appearance of an emperor.

She is very self-aware of her talent. Let alone the Immortal Emperor in this life, even the Immortal King realm is a high mountain for her and impossible to cross.

But with a child who looks like an emperor, the situation is completely different.

During the following banquet, the atmosphere became much more harmonious. The three of them exchanged glasses, chatted, laughed and played, as if they had suddenly become a close couple.

Zhao Mu was also very happy.

This is a living heart of the emperor.

It was much better than the Heart of the Ancestral Dragon he had obtained before.

The key has not been returned yet.

Zhao Mu didn't even dare to think about what the result would be if it exploded ten thousand times and was returned.

But now it’s important to get down to business.

Full of wine and food.

There happened to be a hot spring pool in the cave, so Liu Xi suggested that the three of them take a bath in the hot spring together, so as to take this opportunity to enhance their relationship.

After all, Zhao Mu and the two sisters have known each other for a short time, and if they suddenly want to have a wedding, although it is not impossible, the two sisters will always feel it is a bit abrupt.

You still have to seize the time to raise the temperature so that it can be easily accepted during the wedding.

But at the critical moment, Liu Xi himself ran away.

"Sister, I will leave my husband to you tonight, and I will come back tomorrow."

After saying that, Liu Xi disappeared.

Liu Yao smiled, knowing that her sister didn't want her to be too embarrassed.

In fact, she can accept it.

Zhao Mu was a little speechless.

He was full of expectations just now.

As a result, the reward was directly halved.

The effect of these two sisters together is that one plus one is far greater than two.

In the hot spring pool, Liu Yao dared to stick to Zhao Mu and said with a smile: "My husband seems a little disappointed."

Zhao Mu nodded and admitted openly.

Liu Yao didn't expect Zhao Mu to be so shameless, and couldn't help laughing for a while.

"Gee... Husband, you can't rush this kind of thing. There will be a long time to come."

Zhao Mu nodded, of course he understood this.

Since that's the case, I won't think too much about it. Let's feel the charm of my sister tonight.

"Husband, it's almost time, how about we..."

The beauty invited her, but how could Zhao Mu refuse? He immediately picked up Liu Yao and flew to the room.

"Liu Yao's favorability +2"

"Liu Yao's favorability +1"

"Liu Yao's favorability +3"

"..."

"Liu Yao's favorability +30"

In the great harmony of life, Liu Yao completely dedicated herself to Zhao Mu and accepted everything Zhao Mu gave to her.

After a night of fierce fighting, Liu Yao's favorability score finally settled at 98, just two points away from reaching full.

To be honest, this was just a deal, and it was beyond Zhao Mu's expectation that Liu Yao's favorability could rise to such a high level all of a sudden.

She lay weakly on Zhao Mu, not even having the strength to move.

"Sir, the power contained in the Emperor's Heart is very domineering and terrifying. You must be careful when refining it and don't be greedy for too much. Otherwise, it may cause the Emperor's Heart to backlash and harm your own cultivation."

Liu Yao used her last strength to say something and then fell into a deep sleep.

Zhao Mu wanted to return the reward immediately, but after moving, he realized that he and Liu Yao were still in a negative distance link. If he moved even slightly, the sleeping Liu Yao would show a painful expression.

Hmm... let's get some sleep first.

Zhao Mu hugged Liu Yao and fell asleep together.

The next day.

Zhao Mu vaguely heard a soft pop, and when he opened his eyes, he saw Liu Yao who had just left him.

After being looked at by Zhao Mu, Liu Yao's face turned red with shame and she wanted to find a hole in the ground.

"Does it still hurt?"

"It doesn't hurt anymore, thanks to my husband's elixir."

"Then sit back."

When Liu Yao heard this, she immediately panicked.

Still coming...

Someone will die!

"Liu Xi is still waiting outside." Liu Yao tried to divert Zhao Mu's attention. She couldn't just suffer the pain herself, but she also had to suffer the consequences of Liu Xi.

Unexpectedly, Liu Xi's voice came from not far away the next moment.

"Sister, brother-in-law, please continue. I have to go out for a few days for something, so you don't have to worry about me."

After saying that, Liu Xi ran away, and this time she really ran away.

Liu Yao had a look of astonishment on her face, thinking that it was all over now and she was going to suffer a big crime today.

A few days later.

"Ding, you give Liu Yao a child, trigger a 10,000-fold return, and get a [Skill Upgrade Card]."

Um? No more SSS-level talents?

Zhao Mu consciously entered the system space to check.

"Skill Upgrade Card: Any ability can be upgraded to the next stage."

It sounds ordinary at first, but it seems to be quite powerful.

If it were in the hands of ordinary monks, the value of this skill upgrade card would actually not be high.

But here in Zhao Mu, the situation is different.

There are no restrictions on skill upgrade cards. Any skill that Zhao Mu has can be used to upgrade its level.

This means that his ancient heritage and unified cultivation system can be upgraded with this card.

Other skills are unnecessary, as they are far less cost-effective than these two abilities.

But should I upgrade the ancient heritage or the unified cultivation system?

Zhao Mu hesitated for a moment and made a decision.

Sure enough, it has to be the ancient heritage.

After all, this is the real inheritance of the emperor. Upgrading it is definitely the most cost-effective.

But when Zhao Mu used the skill upgrade card, he was speechless.

This skill upgrade cannot be used to directly upgrade the inheritance or the entire cultivation system, but can only upgrade a single ability.

He can upgrade the ancient giant body and the Qinghuang fighting spirit, but not the ancient heritage directly.

In this case, he has to weigh it carefully.

Wait...

Zhao Mu suddenly thought, is the system's return ability also considered a skill?

Zhao Mu plans to try it.

"Ding, do you want to upgrade the return ability? After the upgrade, the maximum return rate will be increased to 12,000 times."

I'm so excited, it actually works.

The upper limit of the return rate of the return ability is 10,000 times. If it is upgraded, it will be 12,000 times, which is an increase of one fifth.

Although it is impossible to get the highest return rate this time, the improvement of the return skill means that the usual return rate will also increase by one fifth, which is definitely very helpful.

Return is the foundation of Zhao Mu's life. Zhao Mu did not hesitate at all when there was an opportunity to increase the return rate.

He immediately consumed the skill upgrade card and upgraded the return skill.

"Ding, the skill upgrade card was successfully used, the return skill was improved, and the maximum return rate was increased to 12,000 times."

Liu Yao looked at Zhao Mu curiously: "What good news is my husband laughing so happily?"

"It's not me who is happy, it's you."

Zhao Mu's words made Liu Yao stunned at first, and she suddenly realized something and immediately checked her physical condition.

"I... am pregnant?"
