The morning passed quickly, and in a short period of time, this group of people dug out more than 300 pieces of gold sand, each of which was very small, the largest was only the size of a peanut grain, and the smallest was only larger than ordinary sand, but more than 300 grains were enough for four or five taels, even if the purity of these gold sand was only about 60 percent, but you must know that the smelting technology itself in this era is not good, even if it is the so-called red gold, the purity is about 80 percent, and 60 percent of the gold sand can be used directly, and the value is equivalent to fifty taels of silver.

"Okay, that's all for today's work, let's go back to dinner and come back tomorrow."

Liu Yuetian wiped his face with his hands, and he didn't know whether it was sweat or mud on his face.

"Master, don't go! There is so much gold sand here, what if someone else digs it up? ”

The little stove didn't want to leave at the moment.

"It's okay, there's a lot of gold here, and it's ...... Without me telling you the place, you won't be able to find one even if you dig for a year. ”

Just kidding, there is a large area of tidal flats here, and the gold sand sinks under the thick silt, if there is no system prompt, even if thousands of people do it, I am afraid that they will not be able to find a few.

"Let's go, let's go back and have a good meal."

Everyone reluctantly left here.

Lunch was very good, the small stove spent two taels of silver to buy four sheep in the market, and played ten catties of soju, everyone ate sweaty, the cold in the body was swept away, this is the most pleasant meal Liu Yuetian came to Tianshui County to eat.

Full of wine and food, except for Liu Yuetian, everyone else went to rest, Liu Yuetian lay on his bed, and his consciousness was connected to the system.

"Exchange for a rice seed!"

Liu Yuetian's consciousness moved, and he saw that his merit value decreased a little, and at the same time, a golden rice appeared in his hand, which was several times larger than ordinary rice, like a peach kernel.

"Rice is excellent, as long as there is water and soil, not disturbed by any natural environment, six seasons a year, a seed can give birth to ten catties of rice, and only one hundred seeds can be planted per acre.

Note: This seed can only be grown by the host, it is ineffective if planted by others, the seed cannot reproduce, can only grow for two years, and will automatically wilt ......... after two years. ”

"System, exchange me for another ginseng seed."

Liu Yuetian communicated the system again.

Immediately, a milky seed appeared in his hand.

"Two harvests a year, equivalent to 50 years of old ginseng, has a great tonic effect, and regular consumption is enough to bring weak people back to the top."

"The seeds of these grains need to be planted in a hidden place, but the seeds of this precious medicinal herb can be planted in this courtyard.

"System, first exchange for two ginseng seeds, and then exchange two snow lotus seeds, two Ganoderma lucidum seeds, and two He Shou Wu seeds."

In just an instant, Liu Yuetian once again had eight more seeds in his hand.

He didn't delay, he immediately got up and came to the outside of the house, and planted these nine seeds in a corner of the courtyard, anyway, the system also said that this medicinal seed is the same as the grain seed, it only needs soil to grow, and it can produce medicinal materials after half a year, but a seed can only grow for one year, and after a year, you need to exchange for seeds.

In this way, Liu Yuetian took Xiao Luzi and others to the river to dig gold sand for three days, and after half a month, he had nearly fifty taels, and Liu Yuetian also found a problem.

Since the tidal flat began to go down more than ten miles of distance, there is a large amount of gold sand, if all the digging weight is more than four hundred taels, if these gold sand comes from the river, then even if it is buried deep in the river, people will find it for thousands of years, but in fact, for so many years, the gold sand hidden in the river is just a legend, and no one has really found gold from the river.

"It really doesn't make sense!"

Liu Yuetian was a physicist in his previous life, and his logical reasoning ability was far beyond others, and now his intelligence has reached a hundred, which can be extremely smart, and all the evidence shows that this golden sand does not come from the river.

Then there is only one reason.

Liu Yuetian looked up at the mountain that stretched for thousands of miles a few miles away.

The source of the Jinsha River is the Zangbo River, the Zangbo River flows thousands of miles and then pours down from the Funiu Mountain to enter here, and after flowing hundreds of miles on the plain, it enters another big mountain again, which is the mountain in front of Liu Yuetian, named Shu Mountain, this Shu Mountain is the barrier of Hanzhong, like a fast screen between Tianshui and Hanzhong,

Liu Yuetian's elder brother, King Hanzhong, was stationed in Hanzhong, why did even Liu Yuan attach so much importance to this Liu Che? It is because of the unique conditions in Hanzhong, where he is located.

There are only two ways to enter Hanzhong from Chang'an, one is to go directly south from Chang'an, and enter Hanzhong through the Shu Road that is known as the natural danger, and the other road is to enter along the Jinsha River downstream through the Shushan barrier waterway, but this waterway basically no one dares to go, because after entering Shushan, the river narrows rapidly, the water flow becomes turbulent, and after sailing dozens of miles, it will arrive at the famous nine bends and eighteen bends, in which the big ship cannot drive, that is, the small boat, and must be those experienced old boatmen to be able to drive through.

Therefore, the road to Hanzhong from the outside is only the sword pavilion that is not opened, there is this dangerous barrier, the outside army wants to enter Hanzhong is comparable to ascending to the sky, and Hanzhong is located in the Xishu Plain, where the climate is suitable and the people are rich in production, enough to make millions of people self-sufficient, Liu Che occupies this blessed land and continues to develop, so far there are nearly 100,000 troops, once the world is in chaos, his 100,000 army can compete with the princes of the world, and he can also establish his own independent kingdom when he retreats, It is almost impossible for the princes to attack Hanzhong, and the princes of all parties do not dare to take action against the Great Zhou now, and part of it is also the containment of Liu Che, the king of Hanzhong, in the rear.

Of course, Liu Che has nothing to do with Liu Yuetian now, he looks at the boundless Shu Mountain in the distance, which should be the reason for the production of gold sand.

"If I guess correctly, this gold sand comes from the Shu Mountain, after the river water impacted the mountain, a large amount of sand and gravel was washed down, most of it was brought downstream by the river, but a small part was washed back by the current, and the water flow slowed down in this tidal flat area and deposited, which allowed the system to scan it."

In order to verify his idea, Liu Yuetian walked several miles along the riverside and came to the foot of Shu Mountain.

The system scanned the huge mountain again.

"The scanning area is one square kilometer, and the gold content reaches seventy taels .........."

Part of the area scanned this time is the mountain, which is indeed richer in gold sand, and the small area reaches fifty taels.

"This is Shushan! It's clearly a gold mountain, but it's not so easy to mine! ”

Liu Yuetian and these people can pan for gold in the river, and it is delusional to want to dig rocks, but there are nearly 1,000 taels of gold sand in this river, and all of them are nearly 10,000 taels of silver, which is enough for Liu Yuetian to spend a year and a half.
