"Oh, got it." Zeng Rong, who was taking care of the table, raised his head and immediately continued to bury his head in his own business.

During this time, he has been going back and forth between Heibao and practicing boxing, and he simply feels that there is not enough time, and Zeng Rong is too lazy to watch one of the two beauties of his age.

"Yo, are you serious?" Seeing Zeng Rong's appearance, Cao Zhihao was very surprised, didn't this guy see a beautiful woman before, didn't his eyes shine?

"Ha, what is Zhu Lu? I'm still very good. Zeng Rong muttered.

"Okay, buddy, you're high-minded." Seeing that Zeng Rong really had no interest in beautiful women, Cao Zhihao didn't bother to pay attention to Zeng Rong, and kept looking at Zhu Lu with his eyes.

Since having a doppelganger, Zeng Rong's life has set off tremendous changes, and after coming to school this time, it has also brought great changes to the normal study life in the past.

In the past, when he was in class, Zeng Rong either read novels or slept, but now it is different, since he practiced the authentic inner family boxing method, Zeng Rong is surprisingly good, and it is not a normal lunch break in the daytime, and he can't sleep if he wants to.

Now in the ordinary class time, Zeng Rong spends all his time in the pile. Anyway, sitting on the chair, the posture is similar to that of the stake, and the butt is slightly off the chair, and no one can see it.

There are more than a dozen classes a day, and in addition to controlling Heibao's eating, he basically spends his time in the pile. In this way, Zeng Rong spent almost ten hours a day on the pile. Spending ten hours a day standing on the pile, let other martial arts cultivators know that they will definitely scold Zeng Rong to the point of blood! Standing piles is the most basic exercise, spending three hours a day to stand on piles has reached the sky, from ancient times to the present, it may be Zeng Rong alone to spend ten hours a day to stand piles.

However, ten hours a day of piling work made Zeng Rong's foundation extremely solid.

Originally, I used to like the life of the collective dormitory, but this time I returned to school, but Zeng Rong was not used to it. During the summer vacation, Zeng Rong will practice boxing at night, but if he practices in the dormitory, I am afraid that in three days, Zeng Rong will be famous in the entire Yucai High School in Linji County, there is a stupid x in the first class of the second year of high school, this stupid x is Zeng Rong!

On the seventh day of school, Zeng Rong finally couldn't bear it anymore, so he went directly to the head teacher and rented a student apartment.

Yucai High School has built a special building near the school, which is a single-room house with a bathroom, called a student apartment, which is specially provided for those who have money and do not want to live in the school. You don't have to pay to live in a dormitory, but if you rent a student apartment, you can pay 300 yuan a month.

A month's accommodation costs 300 yuan, which is definitely not affordable for ordinary students.

Four months in a semester, the rent is 1,300 yuan, which is still within the affordable range for Zeng Rong, who has earned more than 3,000 yuan throughout the summer.

Living in a student apartment, Zeng Rong began a life of practicing pile skills during the day and boxing at night and early in the morning.

In the eyes of his classmates, Zeng Rong slowly became a loner weirdo, in addition to Zhang Dingyun, Cao Zhihao and Cai Xingtao were able to maintain normal relations with Zeng Rong.

Heibao has been in the Dabie Mountains for nearly half a month, and the ore here is quite attractive to Heibao, and even makes Zeng Rong have a thought, is this ore a drug such as opium and marijuana compared to Heibao?

In half a month, the mountain has been gnawed out of a big pit by the black treasure, and there is a large pile of black treasure excrement on one side of the big pit, but fortunately, the black treasure swallows ore, metal and the like, and there is no peculiar smell except for the smell of rust.

Usually Heibao wakes up and eats, and falls asleep after eating, Zeng Rong doesn't know how to come to this day, after Heibao is full, he suddenly circles the big pit.

Looking at this space, which was already five or six cubic meters in size, Zeng Rong was quite proud in his heart, in the depths of Dabie Mountain, the interior of a mountain peak made such a space, how many people could do it!

This turn happened to come to the location where Heibao stacked the excrement, and suddenly, in Heibao's night vision, several places in the pile of excrement flashed a few shining brilliance.

"What's that?" Zeng Rong was puzzled, swam to the place where the flash, and swept his tail and fell off with a sweep of a fish's eyeball.

Heavy, yellow, with a metallic texture. In the past, when swallowing iron, there would also be incomplete iron in the stomach and intestines to form a grain of iron to be discharged, this time seeing this thing, Zeng Rong said in his heart, "Sure enough, this stone is a metal ore." ”

Brass or gold?

The yellow metal, Zeng Rong knew was copper and gold.

Then he swept the yellow metal body the size of the fish's eyes with his tail, which was unusually heavy.

Copper, Zeng Rong has often seen it in Zhang Dingyun, and when Heibao devours metal, occasionally Zeng Rong also gets some copper for Heibao to swallow, so Tong Zeng Rong is still relatively familiar.

This is definitely not copper.

Suddenly, Zeng Rong thought of another question, when he was fed copper before, copper was obviously more attractive to black treasure than iron.

The nose sniffed at the yellow metal. Sure enough, a rich, black treasure flavor came out of this metal body!

If you don't know that this is found in the excrement of the black treasure, the black treasure will definitely eat it immediately! Resisting the idea of swallowing, compared with the taste of copper, Zeng Rong immediately distinguished, this is not copper! This is a more attractive metal than copper for Black Treasure!

Gold for sure! So much information was intertwined, and Zeng Rong immediately determined it.

You bring tears to my eyes! Dude, no wonder you like to eat this ore so much, it turns out that this is a gold mine! Zeng Rong said to the black treasure in his heart. It turns out that all you eat is gold!

The international gold price has reached more than 1,700 US dollars per ounce, and the domestic gold price has reached 3560 yuan per gram.

Thinking of the gold that is rising in price every day in the gold store, Zeng Rong shuddered in his heart, and the opportunity to make money has come again!

And this time there is no risk, inside the mountain, there will be no people and animals at all, Heibao just eats, just pulls. Those gold that has not had time to digest, but have formed gold grains in the body of the black treasure will be pulled out, and these are all tickets that are pulled out!

The tail swept over the excrement, for fear of missing even a grain of gold.

As soon as I started class, I slept with my head propped up, and the books on the table were piled high there, and the teacher didn't pay attention. Besides, teachers generally don't bother to care about poor students like Zeng Rong. Zeng Rong slept all afternoon under the strange eyes of his tablemates.

In fact, Zeng Rong cleaned up the black treasure excrement for an afternoon.

The results were good, and more than 300 large and small gold grains were found in it, and the size of these gold grains was relatively uniform, each of which was about 1.5 grams, and more than 300 pieces were put together, and there were no more than 500 grams.

"The gold in the gold shop is more than 400 yuan a gram, and I can always sell it for 300 yuan a gram, right?" The economic situation of Linji County has been good in recent years, and people wearing thick gold necklaces are often seen on the street, and the price of gold is also quite popular. Zeng Rong still knows the price of gold relatively well.

Five hundred grams of gold, one gram of three hundred yuan, Zeng Rong calculated, this small pile of metal can be worth 150,000!

Heibao caught a rabbit for a month, and only earned more than 3,000 yuan, and now he eats and sleeps here, sleeps and eats, and he can earn 150,000 yuan in half a month! This made Zeng Rong a little difficult to accept excitedly.

"X, I knew I would have come here early in the morning, eat, sleep, sleep, and make a lot of money without doing anything!" Zeng Rong couldn't help but say a swear word in his consciousness, Hei Bao couldn't speak, and Zeng Rong could only swear in his consciousness.
