After the beast world boss read my mind, I became a goddess

Yu: "Okay, I also want to see what the candle you mentioned is."

Paraffin is needed to make candles, and paraffin needs to be extracted from petroleum, but finding petroleum is rather troublesome.

If we have petroleum, we can also refine kerosene and make kerosene lamps for lighting. Just add some kerosene in a container and put a cotton thread in it, and it will burn for a long time.

Oil is a brown-black flammable liquid extracted from deep underground. There are no detectors or excavators in the Beast World.

If you want to find oil, you can only dig blindly by hand, which will waste a lot of manpower and time.

However, the Orc Continent is underdeveloped and must not know the use of oil. There must be a lot of oil underground.

"Yu, have you ever seen brown-black flammable liquid deep underground?"

Yu shook his head. "I have always lived in the sea. I have been well-dressed and well-fed since I was a child. I have never dug the soil myself. If there are things growing on the seabed, I know everything about them."

"Why are you asking about the flammable liquid deep underground?"

"Oil is needed to make candles for lighting. Oil is a brown-black flammable liquid dug from deep underground. Oil is not found everywhere. I don't know where oil can be found so deep underground."

Yu: "Tomorrow I will go dig a hole with others to see if we can dig out the oil you mentioned."

Lu Qingqing: "Thank you, Yu. Blind digging will waste a lot of time and energy. It would be best if we can dig it up. If we can't dig it up, forget it."

Orcs have strong night vision and can see things clearly at night. The presence or absence of lighting does not affect their living habits.

But she is a human, her night vision is not as strong as that of the orcs, and she is also afraid of the dark.

Females are generally afraid of the dark, so if you have lighting, it will be welcomed by females.

Lu Qingqing snuggled in Yu's arms, Yu's fishtail flashing with a faint fluorescent light, which was dazzling even at night.

She has loved mermaids since she was a child and has fantasized about becoming a mermaid. She wished she could have such a beautiful fish tail.

Lu Qingqing stroked Yu's fish tail and exclaimed, "Yu, your fish tail is so beautiful. It glows at night. It's amazing."

Yu Wan'er smiled and said, "Not all male mermaids have glowing tails. Only the tails of the royal male mermaids have glowing tails."

"This is also the best proof of the royal bloodline of the mermaids. However, there are few female mermaids, and the number of royal family members born is decreasing."

"There are only three mermaid princes in my generation. Qingqing shoulders the responsibility of reproducing offspring. In the future, you must give birth to more cubs with royal blood."

Lu Qingqing: "Can newborn mermaid babies swim? When our babies are born, we will raise them in the pond outside."

Yu: "Yes, mermaid babies are born with the ability to swim, and they cannot stay out of the water for long periods of time. Their skin will easily become dry, so they must be kept in water for a long time."

Raising a mermaid baby is almost like raising fish. She is not good at taking care of babies in the water, so after giving birth to the mermaid baby, she will give it to Yu to raise.

Yu kissed Lu Qingqing gently on the forehead, "Qingqing, it's getting late, go to bed early!"

"it is good."

Yu hugged Lu Qingqing and fell asleep, and they both gradually fell asleep.

The next day, early in the morning.

Lu Qingqing came out of Yu's cave and saw Hu Zi and Mao Ning still waiting at the cave entrance.

Both of them had dark circles under their eyes. They had not slept all night and were in a very bad mental state.

Seeing the little female walking out of the cave, Mao Ning and Hu Zi became extremely alert, fearing that the little female would find out that they had not slept all night.

Lu Qingqing looked at the two of them and asked, "Why are you still guarding here? Didn't you sleep all night last night?"

Mao Ning said guiltily: "We are not trapped. It is our responsibility to protect you."

Hu Zi: "Yes, we are not sleepy."

The two men said they were not sleepy, but the haggardness on their faces and the dark circles under their eyes betrayed them.

If they continue like this, their bodies will break down.

Lu Qingqing: "You don't have to follow me around day and night. You don't have to guard me at night anymore. Go and have a rest! If you get sick, how can you protect me?"
