I am the son of the Dragon God in Douluo Continent.

"Bloodline connection? What is that? Is it like a life-sharing contract?"

The Dragon Emperor and the Diamond Dragon King looked at Xu Xingyu with puzzled expressions. Although their plane had things like mount contracts, they hadn't made much progress in that area, simply remaining at that level without conducting any further research.

Therefore, it is perfectly normal not to know about the bloodline bond.

To let the Dragon Emperor and his wife understand in detail what the so-called bloodline connection was all about, he generously explained it to them.

"From a certain perspective, your understanding is quite correct, because the bloodline connection is indeed very similar to the life-sharing contract, and in some ways, this contract is derived from the life-sharing contract."

"Simply put, this contract will connect the bloodline power of the two parties, allowing them to enhance each other's strength and inject the other's life force into one party at a critical moment, but only if both parties are willing."

"This contract is different from the mount companion contract in your plane. There are no racial restrictions. As long as both parties are willing, you can form a bloodline connection contract regardless of your race."

"If you use this method to help your daughter, you don't need to worry about the attributes or finding human assistance mentioned before. You can make a contract with your daughter yourself and then share your life energy with her. At the same time, with the power of the contract, you can also slow down the eggshell reinforcement process to some extent."

Upon hearing this, the Dragon Emperor stroked his chin thoughtfully and asked, "Does this bloodline bond contract have any side effects? I think every contract comes with a price, right?"

"Hmm." Xu Xingyu nodded and said, "As the saying goes, everything in this world follows the law of equivalent substitution. Bloodline connection, a contract with countless advantages, also comes with a price to pay, and there are two prices."

"The first cost is that if the difference in bloodline power between the two parties who are forming a bloodline connection is large, the weaker party will gain many benefits, such as bloodline advancement, etc., but conversely, the party with the stronger bloodline will be weakened to a certain extent, and sometimes the bloodline may even be contaminated because of this contract."

"The second cost is that this contract is derived from the life-sharing contract, so if one person dies after entering into the contract, the other person will also die."

"Of course, it's different from the life-sharing contract. It's easier to break this contract. At most, both parties will suffer some backlash after breaking the contract, but they'll be fine after a few days of recovery."

"I see," the Dragon Emperor murmured to himself, "In that case..."

Before the Dragon Emperor could continue, Irina, the Diamond Dragon King and his wife, suddenly spoke up: "Let me and the child form a bloodline connection!"

"No way!!!" the Dragon Emperor immediately shouted.

However, the Diamond Dragon Queen Irina retorted defiantly, "My mind is made up! I'm willing to sacrifice anything, no matter how much life force, to ensure my child's safe delivery!"

The Dragon Emperor refused without hesitation, saying, "No!!! Even if you have a tenth-level cultivation, the life force our daughter needs to hatch is considerable. If you overuse your life force, you will suffer irreversible damage!!! This should be done by me, with my Saint-level cultivation!!!"

But his wife, Irina, wasn't so easily persuaded. She immediately retorted, "You are the Dragon Emperor, the protector of our dragon race!!! The dragon race can live without me, but it cannot live without you, our pillar of strength!!! Even if you possess Saint-level cultivation, the life force you lose is not so easily replenished!!! And if this action weakens you, it would be even more unacceptable!!! Our children need your protection to grow up healthy!!!"

"Uh... but our children need your company too!" At this moment, the Dragon Emperor was not as heavy-hearted as before. It seemed that he was temporarily stunned by his wife's words. After all, his wife was right. The dragon race could do without the Diamond Dragon King, but it could not do without him, the Dragon Emperor.

However, he didn't want his wife to die young! Admittedly, he had four other dragon king wives, but the one he loved the most was the Diamond Dragon King in front of him. If he could, he wouldn't want Irina to sacrifice herself.

Just then, an untimely voice suddenly rang out: "Ahem, I know you two are having a rather heated discussion, but could you please let me finish? Although my plan is for one of you to form a bloodline contract with our daughter, when I said this contract would allow you to transfer life force, it didn't mean I wanted you to do it."

""ha?!?!?""

Xu Xingyu then produced an earthen-yellow dragon pill in her hand and continued, "My idea is for you, Dragon Emperor, to form a bloodline bond with your daughter, absorb the power of this dragon pill, purify the energy, and then transfer it to your daughter through the bloodline bond."

"This dragon core is something I obtained before I came here. It is the dragon core of the first Earth Dragon King, containing the purest bloodline of the Earth Dragon King and the divine position of the Earth Dragon King."

"I remember I mentioned before how the dragons of your Five Elements Plane were born? Your progenitor, the Dragon Ancestor of the Earth Dragons, descended into the nascent Five Elements Plane in the form of a dragon egg during the Dragon God War."

"The ancestor of the earth dragons not only has the bloodline of the mountain dragon king, but also the bloodline of the earth dragon king, making it a rare dual dragon king bloodline among the ancient dragon race."

"This also means that you, as his descendants, also possess the bloodline of the Earth Dragon King. In fact, it can be said that your so-called Diamond Dragon Clan is the product of the fusion and mutation of the Mountain Dragon King's bloodline and the Earth Dragon King's bloodline."

"Therefore, when you give the energy from the Earth Dragon King's Dragon Pill to your child, it will also stimulate the potential Earth Dragon King bloodline in her body, thereby strengthening her own vitality and helping her hatch."

"Besides, the Earth Dragon King lineage possesses abilities that help the Mountain Dragon Kings, who have transformed into mountains, to clear away insects and other pests. Therefore, the dragons who inherit the bloodline of the Earth Dragon King are the only dragons capable of breaking through the stable attributes of the Mountain Dragon King. That makes it easier to break the eggshell that traps your daughter."

"As for the energy that your daughter can't absorb, you can absorb it yourself. This way, your daughter will be born smoothly, and both you and your daughter will have the opportunity to inherit the position of Earth Dragon King."

"Don't you think this method is much better than directly transferring life force?"

The Dragon Emperor and his wife stared at the boy with a bright smile, somewhat dumbfounded, their expressions conveying a sense of "Why didn't you say so sooner?"

Xu Xingyu could only maintain a smile and say, "Hehe!"
