Tianchu was like an old ox plowing the field, pushing all the way, and the doctor not far away looked at it in his heart, and at the same time couldn't help but admire.

There are people in this world who dare to collect medicinal herbs like this, especially this kind of medicinal herbs that have lasted for many years, just like pulling weeds, I am afraid that it is the only one.

However, the doctor immortal also shook his head slightly, the number of medicinal herbs in the place occupied by Tianchu is indeed large, but the grade is not high, the highest is the second grade medium grade, and the place where the doctor is immortal is different, most of them are in the B ranks, and a very small number of them have already stepped into the C ranks.

As for why there have been no higher-grade medicinal herbs in the past thousand years, this is mainly because of the qualifications of medicinal herbs, which brings limitations to medicinal herbs.

Generally, it takes three or five years for Grade A herbs to mature and sow seeds from germination, Grade B is short for more than ten years, long for hundreds of years, or even hundreds of years, and Grade C takes at least a hundred years.

Moreover, once the herb is ripe and sown, the herb loses its medicinal effect, and the essence it needs is distributed in the seeds that drift away in the wind.

This is also the reason why this medicinal field is full of medicinal herbs.

Feng Biqing took away a lot of herbs that he was more satisfied with, turned around and left, as if he didn't want to be with a few more people.

For Feng Biqing, the doctor didn't say anything, just gently pushed the box behind him, and then sat on the side of the road to study the remnants in his hand.

The swordsman also quickly ended the looting and took only the herbs he needed.

Dark Youji originally wanted to take away the herbs she needed and withdraw, but seeing where Tianchu was still cultivating the land, Dark Youji also buried her head and started the locust transit mode.

Although I don't know why Tianchu attaches so much importance to Grade A medicinal herbs, there is always nothing wrong with helping to collect them together.

Just half a pillar of incense, half an acre of medicinal herbs, not a single plant is left, all packed into the space bag, as for the nine-square grid, Tian Chu does not have the slightest idea, so many kinds of medicinal herbs, the nine-square grid can accommodate it.

Stretched out his slightly sore arms, looked at the sides, and actually had to fight the herbs that had not been collected, and there were some low-grade herbs among them.

"Come on, thank you!"

Tian Chu hugged his fist proudly towards the two, turned around and ran over, continuing his grand cause.

There are some herbs that Tianchu doesn't know, it doesn't mean that the system Lao Wang doesn't know, there are a lot of herbs that seem to be of low grade, but in fact, most of them are not yet mature.

The doctor immortal and the swordsman actually know it, but there is no way, before it is fully grown, even if he picks it back and plants it again, it is impossible for the herb to continue to survive, and if he doesn't pick it now, maybe there will be a chance to come in the future.

Seeing Tianchu's appearance, it is worth shaking his head slightly, and he secretly hates in his heart, why do you want such a stunned person, the herb is so ugly, don't you know if it has grown.

Tian Chu doesn't care so much, he has cultivation skills, as long as he doesn't die, he doesn't care if he is mature or not.

After the search, Dark Youji handed the space bag in her hand to Tian Chu, Tian Chu smiled, took the space bag, and directly put it into the Jiugong grid.

The doctor is still looking at the remnants in his hand, holding the compass in his right hand, gesturing from time to time, and babbling from time to time.

After a few days of following the doctor immortal, Tianchu also understood in his heart that the medical immortality was calculating the formation, simply put, it was the permutations and combinations in mathematics.

Each formation is composed of small formations, which are mixed together through means to piece together a more powerful formation.

After half a day, the doctor did not stop dying, got up and walked forward.

In the past, there was a village, about a dozen wooden houses to be exact.

One person walked inside, and as for Feng Biqing, he seemed to look down on this place, and directly skipped the wooden house.

Tian Chu chose a room and walked over, the ring buckle on the door panel was a little old, and the rust spots showed that no one had entered the house for a long time.

Gently push the door open, the room is very simple, a solid wood table, an oil lamp on the table, there is a small half of oil in the middle that is not burning, and an emerald green wick lies quietly.

A simple bamboo mat next to the table, a futon made of Bodhi rhizomes, and nothing else.

Tian Chu's face was happy, it was naturally impossible to be bad if he could go through the devastation of so many years without decaying.

This time, Tian Chu didn't use the space bag, and directly incorporated it into the nine-square grid, but the strange thing was that the three objects only occupied one grid, which made Tian Chu extremely curious.

After careful inspection, even the ground was knocked by Tian Chu several times, knowing that there was no secret room or anything below, and Tian Chu could only walk out of the door.

As soon as he walked out of the door, Tian Chu was startled, and the other three actually looked at him directly, as if they were looking at monsters.

"What's wrong?"

The doctor shook his head, turned around and continued to walk, the swordsman did not speak, turned to follow.

Tian Chu only looked at Dark Youji, and Dark Youji didn't seem to want to say more, pointing to Tianchu's back.

Tian Chu turned his head and looked at it, and was suddenly startled, the dozen or so wooden houses just now were gone, as if they had never appeared.

"I'm going, did I touch a certain mechanism?"

Tian Chu muttered secretly in his heart, and looked at the Jiugong Grid at the same time, this time Tian Chu was not lightly frightened, it was originally a three-piece set, but now it has become a twelve-piece set.

Looking at the twelve wooden houses in Jiugongge, Tian Chu looked confused, and the next moment he was ecstatic, I don't know how many years of wooden houses, will this material be worse?

After being excited for a while, Tian Chu calmed down, Tian Chu strode to follow, if he fell behind, Tian Chu didn't think he had the ability to leave.

The main thing is that this outermost layer is such a good baby, and if you go a little deeper, the benefits don't need to be mentioned.

Suddenly, the doctor didn't die, and the three of them naturally stopped, this kind of place follows the master, safe.

The doctor did not die, and his mouth began to chatter, and when he calculated, the compass in his hand also kept swinging, and the amplitude was limited.

After a long time, a trace of sweat oozed from the forehead of the immortal.

"Let's go!"

The doctor directly took back the compass, shouted, and strode in.

The other three naturally followed suit, for fear of making a mistake.

At this time, the doctor turned his head and smiled slightly, "This time, everyone is free!"

The three of them suddenly chuckled in their hearts, and the swordsman, who had a calm face, changed his face slightly.

"Old doctor, don't make such jokes!"

Tian Chu opened his mouth and said, here is the swordsman and the dark Ji, both of them are people who don't want to talk more, and this question naturally comes from Tian Chu.

The doctor didn't die, but his face was relaxed, "Believe it or not!"

"Lost thunder!" Tian Chu's violent temper was quickly suppressed.

If you don't suppress it, you can't do it, because the world in front of the four people is spinning, the road ahead is flickering, and there seems to be a figure floating, but if you look closely, there is only half of the body, and half of it seems to have been cut off by something.

"Don't be afraid, I won't die and walked through countless secret tombs, and that time I didn't walk out alive!"

The doctor said proudly.

But the other three didn't think that along the way, the doctor would hardly speak, unless there was something important, and the doctor would like to push the box on his back the most.

This time, the doctor is not just a chatterbox, but since he entered the formation, he has not moved the box behind him.

Feeling the eyes of the three of them, the doctor smiled, and pushed the box behind him with his right hand, "It's just a remnant formation, don't be afraid!"
