“fire in the hole!”

Nan Ruoping lit the fuse of the gun, covered her ears and ran to the side.

Nan Yi stared at the pointer on the instrument. As the gun exploded with a bang, the pointer began to shake.

"Dad, how's it going? Is there a treasure cave?"

"From the perspective of wave impedance, there are only hollows in wells and underground waterways, not treasure caves."

"Ah, there is no treasure." Nan Ruoping said disappointedly: "Dad, my great-grandmother said that these two instruments are very expensive."

"Haha, if there is no hole, it doesn't necessarily mean there is no treasure. Dad will use a gold detector to take another look. Maybe there will be big gains."

"Will there be gold?"

"Maybe there is. If you find it, daddy will give you two."

After the underground cavity detector detected no holes in the ground, Nanyi put the detector aside, took the gold detector in his hand, turned on the instrument, and the large disk of the detector swept over the ground in the yard inch by inch.

.

Didi didi!

At the beginning, the instrument made a beeping sound.

Nan Yi inserted a bamboo stick into the ground and continued to sweep forward, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep, beep.

The accurate detection range of this instrument is about five meters, and the subsequent alarm may not necessarily indicate any new discoveries.

Nan Yi no longer scanned inch by inch, but walked to the corner of the yard and scanned from the edge to the middle. The little girl Nan Ruoping followed Nan Yi, even more nervous than Nan Yi.

When you hear the beeping sound, your little eyes will light up.

"Dad, is there gold?"

"I don't know. The sensitivity of this machine is not very good. It might be other metals."

Nan Yi said this, but actually he didn't think so in his heart.

Although this detector is not 100% accurate, its sensitivity is actually quite good. With such a strong response, it is almost certain that there is gold underground.

Although the detection was very careful, the courtyard was only that big in total. In more than an hour, Nanyi had completed the detection of the entire courtyard.

The bamboo sticks on the ground were connected in series to form a fan-shaped area with the well as the center and a radius of 3.2 meters, which had a strong metal reaction.

"3.2×3.1415926÷360×100≈3㎡, Dad, how much gold can be stored in 3 square meters?"

"Your question is very problematic. If you don't know the thickness, you can't calculate the volume. But let's assume that there is just one layer under the ground. The default thickness is 8 mm. The density of gold is 19.32 grams/cubic centimeter. If you

, you do the math."

"Okay." Nan Ruoping nodded and started to count, "3 square meters is 30,000 square centimeters, 30000×0.8=24000 cubic centimeters, 24000÷19.32=1242, dad, it's not much, only two kilograms

A little more."

"Haha, it's quite a lot. If there is really gold down there, then the two kilograms you mentioned is the minimum amount. How many meters is the thickness?"

When Nan Yi heard that it was two kilograms, he didn't react for a moment and thought that the little girl had made a mistake. But as soon as his mind changed, he immediately thought that Xiangguan used "Sima Liang", one kilogram is sixteen taels, and one tael is 37.4 grams.

, 600 grams is one pound.

"One meter is two hundred and fifty catties, two meters is five hundred catties, ten meters is two thousand five hundred catties, one hundred meters..."

"Okay, stop daydreaming. One or two meters deep would be great. Do you still expect to dig through the earth?"

"Hey hey hey!"

Nan Ruoping giggled.

Nan Yi fell into deep thought, "If a large amount of gold is dug out from the ground, then the Liu family's wealth will be a bit excessive. Could it be that the son-in-law of the Liu family is in charge of logistics in the Guangdong army?

Damn, that’s a lot of military pay.

However, it doesn’t matter where the gold comes from. I don’t care where it comes from. The younger son of the Liu family is a hidden danger, and we must find this person as soon as possible."

"Dad, when are we going to dig?"

"Don't worry, dad will cook. After dinner, we will take a nap. We will sleep well during the day and then dig again at night."

"Uh-huh!"

After lunch and putting the little girl to sleep, Nan Yi's mind started to spin again.

"The temperature of the well water is low, which is not surprising. The well may have been dug in the cold water zone of the groundwater. The fact that the two snapping turtles did not enter hibernation is worth pondering.

Also, there was no food chain in the yard at the beginning, and there was probably a tunnel leading to the outside world. But I have surveyed the entire house, and there is absolutely no secret tunnel.

The first time I came to South House, the courtyard door was closed, and there were no ivy or other plants on the courtyard wall. Where did the poisonous snake enter the courtyard?

Courtyard gate, threshold, screen wall, dog hole...

Um, dog hole?

Why had I forgotten the dog hole? It had not been taken care of for many years. The yard was dark, damp, and overgrown with weeds, which breeds various insects and attracts toads. The presence of toads also attracts venomous snakes.

This seems to make sense.

However, there are too many venomous snakes. How to explain the territorial awareness of venomous snakes?

Could it be that the Liu family is still a snake-playing group of people?"

The more Nan Yi thought about it, the more clues there were and the more unclear he became.

Perhaps, there is no big treasure house underground at all in the south house, but there is a "key" to open the treasure house.

Nan Yi actually already had a guess. Those two strange snapping turtles might have some clues engraved on them that lead to a treasure house... words, numbers, and graphics are all possible.

If Nan Yi's conjecture comes true, he will not feel happy.

The more confusing the identity of the Liu family is, the greater the threat to him is the younger son of the Liu family.

Digging for treasure?

After eating enough to hold on, Nanyi has little interest in digging for domestic treasures, even those from abroad.

Whether it was the Fengwen treasure at the foot of the Philippine mountain or the German treasure, when he was bored, he had studied it carefully and he roughly knew where it was buried.

But are treasures so easy to find?

The original indigenous old people in Southeast Asia are not dead, and the old devils are not dead;

The ** is not dead, and the Jewish revenge organization back then is not dead. If Nanyi dares to touch the treasure they have been thinking about, he will face their fire, so he can just wait and escape in a hurry.

Making a fortune by digging for treasure is something more outrageous than winning the lottery and getting your first pot of gold.

Maybe when the Nan family is strong enough, and when they are free, they can form a few treasure hunting teams to explore the secrets of the earth.

At the moment, it is better to do business down-to-earth, and when the strength is almost accumulated, then think about the oil deposits and gold deposits that have not been explored yet, so as to realize the rapid appreciation of wealth.

…

It's past ten o'clock in the middle of the night.

Nan Ruobing was sent to the wall by Nan Yi to look after the wind. He dug in the yard by himself. He used a hoe to dig up the ground, and then put on the shovel and pickaxe.

Dig, keep digging.

At one o'clock in the morning, the shovel made a clanging sound and sparks came out.

Nan Yi knelt down and dug into the soil with his hands. A piece of oilcloth came out of the soil, and bursts of golden light blinded his eyes.

Nan Yi continued to pull calmly until the entire oilcloth was exposed to the soil. Nan Yi used a shovel to cut open the oilcloth, and golden square pieces fell out from the oilcloth.
Chapter completed!
