The two of them searched carefully around again, but found nothing of value except for a few stone chairs that were not neatly arranged next to the stone table.

"Looks like we can't find anything useful here. Even if there was anything of value, it would have to be behind that door, so let's see if we could open the stone door. Zuo Liancheng once again returned to the stone gate in the corner, put his hands on the door, and carried all his Yuan Force, then roared and pushed forward violently. However, under the huge pile of three or four hundred catties, the stone gate still did not move.

Seeing this, Josia also hurriedly walked over. The couple stood side by side while standing on the door with their hands outstretched. "One, two, three!" both of them counted at the same time, and when they counted to "three", they tried to push the stone door open with brute force. But the two of them were soon disappointed, and although the two of them almost used the strength to feed, Shimen still remained the same, not moving at all.

"Don't push, brute force will definitely not work. "After several attempts, both were out of breath. Josia withdrew her hands, "Let's find a door opener." ”

Zuo Liancheng no longer insisted, so the two began to feel here and there in the stone house, knocking there, carefully looking for the mechanism to open the door. However, half an hour passed, not to mention the mechanism, not even a handle or button was found. In desperation, the two sighed at each other, left the hall, and returned to the stone platform stacked with dead grass at the entrance of the cave.

The fire at the entrance of the cave was not extinguished by the long absence of the two, but the fire was much smaller than before.

"I'm going to get some branches, this fire can't be extinguished, or it's dangerous to spend the night here." Zuo Liancheng greeted his wife, then picked up the long sword and walked out of the cave.

There were many trees at the entrance of the cave, and the light of the fire was lit, and it didn't take long for Zuo Liancheng to bring back a large number of dry or wet branches.

The night was already dark, and except for the occasional roar of beasts, all around was the long or short, high or low neighing of various autumn insects. Today is the end of September, and the moon in the sky has not yet risen, although the stars have diluted the thick night a lot, but except for the small space illuminated by the firelight, the mountains and trees in the distance are all immersed in the boundless dark night, which is particularly mysterious and profound.

The two chatted for a while, and before they knew it, it was almost midnight. "Rest early, it's getting late. Zuo Liancheng stood up, stretched long, and then put a few thicker branches on the fire, and then turned back to his wife and said.

"Well, get some rest early. Today I have worked in vain, and I haven't picked any medicinal materials, so I hope that tomorrow will be a little better. Josia also stood up, put a pile of stones at the entrance of the cave and stacked it into a stone wall more than a meter high, and then tied a bell to the outside of the stone wall. In this way, even if there is a beast attacking, it can also play a certain role in protection and early warning. As for their horses, they had been brought into the cave long before dark. Although the horses of the two have good foot strength and great strength, they have no combat power, and once they encounter a beast, they basically have to flee for their lives.

After the two of them had settled everything, they didn't use the haystack on the stone platform, which I don't know what age it was, and it shattered into powder at the slightest touch. The two of them spread the felt they brought with them on the ground to make a simple bed. The husband and wife are both people who have been hunting in the mountains for a long time, and they have long been accustomed to this difficult wild life, and it didn't take long for the two to have sweet dreams.

There was no word for the night, and by the next morning, when the two of them woke up from their sleep, the sun had already risen over the mountains in the east. The crystal clear dew drops sparkle in the sunlight, like colorful pearls.

The two of them quickly finished their breakfast, and today they had to go to find the other two main materials needed to refine the Replenishing Yuan Pill, the Soul Returning Grass and the Essence Blood of the Blue Blood Silver Snake. These two kinds of medicinal materials are not easy to find, the blue blood silver snake is different from ordinary snakes, once this snake is promoted to the third order, although its body has not changed much, it can already use simple magic to attack. The Bloody Silver Serpent is an icy species, with a snow-white body and a turquoise blood. Before the promotion, most of the blue snow silver snakes lurked in the fields, feeding on various frogs, birds and beasts, and did not do much harm to humans. However, as it progressed, the poison of the Blue Blood Silver Snake became stronger and stronger, and its living space gradually shifted to the depths of the forest. Those Blue Blood Silver Snakes who had advanced to the fifth order, although they could not transform into human form, were also overlord-level existences. Of course, like other demon beasts, the more advanced to the end, the fewer their number. The Blue Blood Silver Snake that has advanced to the third level is already extremely rare, and those who have advanced to the fourth and fifth orders or even beyond the fifth order only exist in the legendary stories.

"I hope we can have better luck today, and we won't be like yesterday, fighting hard for a long time, only to get nothing. Josia said as she sorted out her things.

"You don't have to be in a hurry, going up the mountain to collect medicine is a matter of luck. If you are lucky, the medicinal herbs that take a few days to collect will be collected in a while, and if you are unlucky, even if you are ordinary medicinal herbs, you will have to find them for several days to come across. Actually, we weren't unlucky yesterday, at least we had found the location of the Ivy League, and the Ivy Vines there were all good years. Our main goal today is to find the Soul Restoration Grass, and it's late autumn, which is the best time to look for the Twilight Grass. Zuo Liancheng was obviously much more optimistic than his wife, not only did he not feel troubled by yesterday's events, but began to comfort his wife.

Zuo Liancheng's mouth said that the soul grass is a very peculiar plant, a section of the plant is the higher the temperature, the faster it grows, although the soul grass can survive in spring and summer, but the higher the temperature, the slower the growth, and after the beginning of autumn, it grows more and more vigorously with the decrease in temperature. This unusual out-of-season growth continues until around the winter solstice. This growth characteristic of it is a bit like the return of a dying person. Resurrection is not an annual herb, and under the right conditions, its roots can live for hundreds or even thousands of years. This medicinal material is the top-grade material for refining and supplementing Yuanli first-class elixir, and the longer the year, the better the medicinal effect. If you come across a soul revival grass that has grown for thousands of years, as long as you dig out its roots, even if you don't use other auxiliary medicinal materials, you can directly put it in your mouth and chew it and swallow it, you can quickly replenish the consumed yuan power. Of course, due to the different cultivation levels that each person has reached, the amount of Soul Restoration Grass needed to replenish Yuan Force is naturally different. All in all, whether it is a martial artist who cultivates martial arts or a mage who cultivates Taoism, this soul rejuvenation herb is their usual medicinal material. It is precisely because of this that there are too many people who collect it, which makes the originally extremely common Soul Rejuvenation Grass become more and more rare. Later, after some people saw the value of the soul revival grass, they began to plant it artificially, but this artificially planted soul revival grass, because it grows too fast, although the yield is high and the quality is good, but it is not as good as the natural growth in terms of medicinal effect.

This kind of soul rejuvenation grass is also specially cultivated in the tribe where Zuolian City is located. However, firstly, the cultivation year is not enough, and secondly, it is a public medicine garden in the tribe, and no one can dig it privately without the permission of the chief. So this time, when Dan Ivan proposed to ask Zuo Liancheng to refine the Replenishing Yuan Pill, the reason why he deliberately proposed that Zuo Liancheng could not use the medicinal materials in the tribal medicine garden was to prevent Zuo Liancheng from mining the soul rejuvenation grass inside.

Before leaving the cave, they prepared enough forage for their horses for several days, and moved them to the lake, where they could drink enough water. The two then used their own water bags to bring water from the lake and filled a stone jar in the cave with water. In this way, even if they do not return to the cave for seven or eight days, the horses in the cave will be able to eat and drink without starving.

You may ask, "Why don't you take your horse with them?" Actually, the question is very simple, it is indeed faster to ride on a horse than to walk on a plain or on a flat road. However, Zuo Liancheng and his wife were going to the deep mountains and old forests to collect medicine this time, and few people entered the deep mountains and old forests, so there were no ready-made mountain roads to walk. The two of them were looking for medicinal herbs in the mountains, and naturally they had to constantly climb cliffs and cross ravines, and it was very difficult for people to walk, let alone horses.

After the two of them had taken care of everything, they set off deeper into the mountains and forests. Along the way, he overcame thorns and thorns, climbed cliffs and crossed ditches, but except for finding some medicinal materials that were not needed this time to refine other pills, there was no gain now. In desperation, the two of them had no choice but to continue to advance into the depths of the forest, and before they knew it, they were fifty or sixty miles away from the cave where they had stayed last night.

"Dad, look, there's a soul revival grass in front of it!", just as the two of them were tired and ready to rest, Josia, who had better eyesight, suddenly cried out happily.

"Really?" Hearing his wife's cheers, Zuo Liancheng also stopped and followed his wife's finger to look ahead.

I saw an open land of about half an acre not far ahead, and all kinds of weeds that had begun to wither and yellow grew in the open field, and some green weeds with only one stem were growing sporadically in the weeds, and two or three inches near the top of the stem, surrounded by four or five long-shaped, erect leaves. This is exactly what the Soul Restoration Grass is. Determining the year of growth is actually very simple, and it can be judged by the number of leaves on the stem. Generally, the soul revival grass under two hundred years old, no more than two leaves, and then every more than a hundred years, another leaf is added, and the soul revival grass seen in front of you has four leaves at least, which means that their growth period has been at least more than three hundred years.

"It seems that there is really no place to find when you step on the iron shoes, and it takes no effort to get it! Let's go over and take a look, since we can see three or four hundred years of soul revival grass on the periphery, if we go inside, we should also be able to see even older soul reviving grass. Zuo Liancheng said as he used the long sword in his hand to split the weeds in front of him and walked towards the open field he had just seen.

However, just when the two of them were full of joy and were about to reach the area where the open field was, they suddenly seemed to hit something, and a sudden force slammed the two of them back. The incident happened suddenly, and the two couldn't regain their momentum, and suddenly fell heavily to the ground.

"What's going on? Someone seemed to have pushed me back with a lot of force. Zuo Liancheng's face was full of astonishment, and he said suspiciously as he got up from the ground in embarrassment, slapping the mud and weeds on his ass with his hands.

"Me too. It looks like someone was pushing me out just now. Josia also had a look of disbelief written on her face.
