Fang Ling didn't take this seriously at the time, he just thought it was the Arabian Night Lake, but now when he saw this vision, he couldn't find any other explanation.

Although I don't know who put this dagger where it was, there is no doubt that it seems that because the dagger cut the palm, the palm has the ability to perform some kind of immortal magic.

His heart was beating wildly, as if a person who had fallen off a cliff had grabbed a lifeline, and Fang Ling faintly realized that this immortal technique was likely to change his fate.

But first, we have to understand what this right palm that has received immortal magic can do.

Fang Ling quickly calmed down, he first took out a cordyceps plant and a piece of deer antler velvet from the medicine bag, and when he held the two in his hand, there was no change.

Then, when Fang Ling held the two Cordyceps together, the warm feeling came again, and in the palm of his hand, the two Cordyceps miraculously merged into one, and the new Cordyceps was slightly larger than the disappeared Cordyceps.

Fang Ling suddenly understood, it seemed that what could be fused must be two identical things. He found two embroidery needles and shook his hand again, and after a while of warmth, the two embroidery needles actually merged together, and the new embroidery needles were not only larger, but also sharper.

After Fang Ling experimented several times in a row, he finally came to a conclusion: this hand can fuse two objects of the same kind, perhaps because his own ability is not enough, it is only useful for objects that can be held, and after fusion, the attributes of the object will be improved.

For example, the first two 10-year-old ginseng roots became about 20-year-old ginseng after fusion.

This discovery made Fang Ling's always calm heart also jump, the price of two 10-year-old ginseng and 20-year-old ginseng must have a big gap, if he can get two 10-year-old ginseng, and then sell them after fusion, wouldn't it be easy to earn the difference between them.

In this way, why worry about running out of money?

As long as you have money, you can take care of everything in the palace, whether it is a eunuch or a doctor, and your mother's health will be better at that time!

However, there was one of the biggest problems for him, and that was the lack of silver.

Although over the years, my mother has earned some silver every month by selling embroidery, but seventy-seven eighty-eight have been used to take some eunuchs, not to mention anything else, just take Xiao Wuzi, the little eunuch who delivers food, for example, he has to give him five taels of silver every month, even so, he often does not send meals on time, naturally the reward is too little.

If you don't have any money in your hand, it would be naïve to buy and sell.

Fang Ling pondered carefully, if he could get medicinal materials in the palace and sell them outside the palace, this would be a real profitable business, and the place with the most medicinal materials in the palace was undoubtedly the Tai Hospital.

He suddenly remembered that every few days, the warehouse of the Tai Hospital had to clean up some medicinal materials that had been damaged due to poor preservation, since this immortal technique could fuse two good medicinal materials into a better one, could it be possible to fuse the broken medicinal materials into intact medicinal materials?

Fang Ling thought so and decided to go to the Tai Hospital again.
