The protagonist chased the villain, and Tiandao screamed in anger

Although many inventions still have some shortcomings, these things are well designed and can be used to defend against enemies after being improved.

You Mu took Luo's things and looked at them carefully, and then carefully pointed out the defects he could think of.

"There are a few problems. The shell can hold too little. If a larger device is used, the drive below will be difficult to drive. As for this, the accuracy still needs to be calibrated..."

"Yes, Mu, you still understand me. I have also been thinking about these things, but there is no better way..." When You Mu came back, Luo found a confidant.

He also knew that these inventions had flaws, but it would take time and effort to find solutions.

"These are not urgent. Have you finished the things that I asked Brother Wang to research before I left?" Putting down the things in his hands, You Mu asked about the purpose of coming here.

Luo Bai straightened the frame and thought for a moment, then dived into the pile of junk and rummaged around, patted the crab claws off his hair, and handed over a small tube of pink medicine.

"This has been prepared a long time ago, but Mu..." Luo brushed the hair away from her eyes. Although she didn't know what the prince wanted these for, she still reminded him seriously, "Although this blood has miraculous effects, we mermaids don't need it. If it is used on humans... humans are cunning creatures, don't be fooled by them."

Luo was worried that his brother would be deceived by humans. The mermaids have many secrets. If humans knew one or two of them, they would be in disaster even if they were in the sea.

Of course You Mu knew Luo's warning. He was not the little mermaid in the fairy tale who would be deceived by humans into giving up himself and turning into foam.

He held the potion against the night-shining pearl above his head. In the viscous medium under the light were strands of diluted light blood. You Mu turned the glass tube and assured Xiang Luo:

"Brother, don't worry, this is to protect Tislanton."

Over the years, humans have caught mermaids and used their blood for research, but they have not found any factors in mermaid blood that can prolong life or heal injuries.

But to this day, the legend that mermaids possess the secret of longevity is still believed by most people.

Immortality is naturally impossible.

Everything has a lifespan, and all things will eventually die. Immortality is a highly deceptive false proposition.

The mermaids did survive for many years, and their individual lifespans were relatively long compared to humans, but they were far from immortality.

As for the peculiarity of the blood, with the changing of times and the continuation of bloodline, that trace of divine power carrying the gift of the sea god has long been diluted.

Although mermaids have strong recovery abilities, the blood of ordinary mermaids is no different from that of humans.

Only the mermaid royal family, whose tail fin has a golden mark, still retains this trace of the unique color, indicating their prominent status.

But the mermaid royal family has a strong ability to control water, and humans cannot catch them in the ocean.

This is also the reason why Emperor Bird risked breach of contract and sent people to launch a sneak attack on that road in an attempt to get a drop of his blood.

But if mermaid blood is so good, how could he have been ill for so long?

If the mermaid is willing and willing to give it, it can be a life-saving medicine that can solve the urgent problem. If the mermaid is unwilling, this antidote can also become a poison.

Rather than saying that mermaid blood is a panacea, it is better to say that it is something similar to poison. It can help the host defeat pathogens, and when necessary, it can also become a new virus for the host.

Life or death depends on one thought.

It’s just the blood of the royal mermaid, which is useless to the same kind. This ability seems to be only aimed at humans.

This is a unique honor bestowed by the Sea God on the darlings of the sea, and it is also the price paid by the mermaid royal family for dominating the sea.

There is gain and loss. When something is too precious and rare, it runs the risk of being peeped, coveted and destroyed.

You Murangluo's research was to make the royal blood contain both antidote and poison. While it seemed to alleviate the condition, the toxicity gradually worsened.

He couldn't allow Bird to pollute the ocean, so in order to stabilize him, he could only let him "get better".

"You always know what you are doing. I rest assured that my father will hand Tislanton into your hands." Luo Kan saw that You Mu had a calm expression and knew that the other party had his own plans, so he did not ask any more questions.

"By the way, has there been any progress on the fish gills that can purify humus that Brother Wang mentioned in his last letter?" The ocean on which they depend for survival cannot be polluted, and in order to prevent accidents, they need to take precautions in advance.

"Yes, there are. The scavenger fish rely on their powerful acid stomachs to digest the waste. The gills are just auxiliary filtering, but digestion takes time. It is impossible to rely on these fish alone to purify the completely polluted waters in a short period of time. If we continue to extract the acid from these fish for purification, it would be too cruel."

"At present, I am still referring to the acid for the ratio, but Mu, you also know that many of our technologies are not as advanced as those of humans, and we do not have the natural advantage of storing supplies..." Luo sighed. This is the disadvantage of the mermaid race.

This is indeed a problem, but it is not unsolvable. Since it does not exist, we can just get some from where it is available.

"Brother Wang, please draw up a rough invoice for these missing items, and leave the rest to me."

While thinking, You Mu made a plan. He put away the medicine tube and asked Luo to continue his research.
