Artificially cultivated medicinal materials themselves are no different from commonly grown medicinal materials. In fact, artificially cultivated medicinal materials are even better than wild ones in essence.

Especially for many fruits, wild fruits are bitter, astringent, sour, not good in taste, and even cannot be eaten. However, after artificial cultivation, those fruits that cannot be eaten will become sweet and delicious.

Artificially cultivated medicinal materials grow faster than wild medicinal materials, and medicinal materials can be obtained easily without a long period of time.

But there is a disadvantage, that is, without the absorption of the spiritual energy of heaven and earth, no matter how perfect the cultivated medicinal materials are, their medicinal effects are far inferior to those of wild medicinal materials, let alone natural treasures.

"Yilin, although there are very few natural and earthly treasures now, if you are determined to look for them, you can still find some..."

After a while, Ning Beichen spoke.

"I believe in your ability. If you want to look for it, you can always find some, but a few medicinal plants are just a drop in the bucket and may only save a few people..."

Liu Yilin sighed and said.

Faced with the huge number of people suffering from cancer, even if Ning Beichen could find some natural treasures, how many people could he save?

"No matter what, you continue to research and think of other ways. I will find ways to find the treasures of heaven and earth. How many people can be saved? It is better than doing nothing."

Ning Beichen said to Liu Yilin.

He is not good at research, but Ning Beichen can still find things. It just so happens that he has been looking for the Cave Heaven Paradise, which does not conflict with his goal.

"That's fine. I'll continue to think of other ways. The road ahead may not necessarily be a dead end. Think about it back then, when you had no choice but to find another way, the road ahead may not be a dead end."

Liu Yilin clenched her fist and said with confidence.

"Okay, let's work hard together."

Ning Beichen saw that her confidence had become firmer, and he was also infected.

Next, Ning Beichen gave an order to the six mortals, asking them to go all out to find some of the treasures he designated.

After the six mortals received Ning Beichen's order, they naturally did not dare to neglect and immediately began to take action.

And the secular forces controlled by them also began to search for heavenly materials and earthly treasures all over the world.

But let alone mention it, with the help of these mortal beings, in less than a few days, a lot of heavenly materials and earthly treasures were found and delivered to his hands.

However, it is still far from Ning Beichen's requirements, because things such as natural materials and earthly treasures cannot be obtained with money.

For things like century-old ginseng and century-old Ganoderma, which are relatively well-known and commonly used, you can still find some of them by spending money to look for them in the market, but for some less popular medicinal materials, you can basically never find them.

However, there is one important medicinal material that Ning Beichen requested, and someone has found traces of it in the tropical Amazon rainforest.

It's just that the place is hard to find, and it's mostly in some very dangerous areas. These places are basically inaccessible, and no one dares to risk their lives to look for them.

So after getting the news, Ning Beichen planned to take a trip himself, because this medicinal material is one of the most important medicinal materials developed by Liu Yilin to treat cancer.

Soon Ning Beichen appeared in the Amazon rainforest, following a local guide beside him.

The place they are going to now is a place called Devil's ditch. After the person's name and the shadow of the tree, this place is called Devil's ditch. Naturally, it is not a good place.

The locals say that there is a devil in this place, and if you go in, you will not come out alive.

Although there are exaggerations, no one dares to enter this place.

The reason is simple, because most of the people who entered died.

And after some people who are not dead run out, they will become crazy and will not live long, and the rumors that there is a devil inside are spread from the mouths of these crazy people.

Over time, Devil's ditch became a place where no one dared to set foot.

But Ning Beichen didn't believe in any devils at all. Even if there were devils, Ning Beichen would take care of them.

There must be brave men under heavy rewards. As long as the money is enough, there will still be people who will take risks, so the guide around Ning Beichen is a guy who is not afraid of death.

However, the guide was still afraid after arriving outside Devil's ditch. After arriving here, he did not dare to go in. Anyway, he kept trying to persuade Ning Beichen to leave.

Ning Beichen didn't force him, he went into Devil's ditch alone and asked the guide to wait for him outside.

Devil's ditch is a ditch-shaped rainforest with a large area, and 80% of it is swamp. If you go in, you will be swallowed up by the swamp if you are not careful. It is estimated that most people don't dare to come here.

One of the reasons.

But for Ning Beichen, this is not a problem at all. Whether it is a swamp or a hard ground, it is like walking on flat ground under his feet. There is no difference.

The only difference is that there are more crocodiles in the swamp, but a few of them have been skinned by Ning Beichen and used as food rations.

When he came in this time, the medicinal material he was looking for was a medicinal material called rotten bone flower.

The rotten bone flower has very high requirements on the growth environment. This medicinal material has almost disappeared in the ancient Eastern countries, so Ning Beichen had to go to the Amazon rainforest to look for it.

Although there is news that there are traces of the rotten bone flower inside, and based on inquiries from some local old natives, they also swore that there was this devil flower inside.

But Ning Beichen didn't know whether it was real or fake, so he had to look for it himself.

Ning Beichen has been searching in Devil's ditch for two hours, but still has not found the whereabouts of the rotten bone flower.

However, the devil's ditch was very large, and there were towering trees and various plants everywhere, and there was a swamp at the feet, so Ning Beichen's search was not very fast.

To find treasures of heaven and earth, speed is not enough. The most important thing is to be careful, careful enough and patient enough.

When he arrived, it was already afternoon. Ning Beichen came in and searched for more than two hours before it got dark.

And Ning Beichen had no intention of leaving. He planned to spend the night here tonight and continue his search tomorrow.

If he went out now and came back tomorrow, he would waste a lot of time.

Anyway, he was alone and the weather seemed to be fine. Ning Beichen didn't even bother to build a shelter and just found a place to spend the night.

He built a bonfire and roasted the crocodiles he got during the day. It smelled delicious after a while.
