Lin Du solved the living beings, and wanted to go out, but his eyes just swept to a stone door on the right hand, but he didn't expect the stone door to open with a light push. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Lin Du went in and found that it was a room-within-a-room, but the scene on the ground directly stunned him!

Dozens of small black holes in the shape of circles appeared on the ground, each of which was distributed around a dark blue grass in the middle, and Lin Du took a closer look, and there were bare corpse bones under the circle.

Mass graves, the breath of the yin source, renew the soul and souls! It's no wonder that the dark blue grass in the middle is the Soul Continuation Grass.

Lin Du Darkness exclaimed, no wonder this stone room was filled with an extremely strong Yin and Cold Corpse Qi, it turned out that the creatures outside survived by devouring the underground Yin Source Corpse Qi.

After thinking about it, Lin Du also felt that it was not strange, the Soul Continuation Grass had been absorbing the Yin Source of the underground corpse bones for many years, as a guide for the soul of the living beings, resulting in these living beings being able to be active in this underground city tomb for a long time.

Soul Continuation Grass, I didn't expect to find it in this situation, and the color of this Soul Continuation Grass is very dark blue, which proves that its age is very high.

Lin Du was obviously very excited in his heart, the main materials of the Soul Continuation Pill were already complete, and there was no problem with the secondary materials.

After Lin Du took the Soul Continuation Grass, he directly used the spiritual breath in his body to refine the Yin Corpse Aura hidden in the Soul Continuation Grass, and then used his spiritual sense to search the surroundings to make sure that there was no spiritual grass with hidden spiritual energy, and quickly left the stone room.

After all, staying in it was really a bit cloudy, and the whole person felt uncomfortable, and after coming out, Lin Du didn't know which way to go, so he picked a big passage at random, and it took him half a day, seven turns and eighteen turns.

Lin Du was also completely stunned now, thinking to himself how big this city tomb was, how could he turn around and get to the place where he first woke up.

Lin Du was completely speechless, the compass here was completely ineffective, and the food in the ring could only last for a few days, and he couldn't help but feel a little impatient at the thought that the members of the Heavenly Strike were still waiting for him to go back.

It's just that I just turned around blindly and found that this city tomb also has a feature, that is, these stone rooms, and there will be an inner stone room on the right hand side of each stone room.

It's just that after going in one by one, I found that they were all rotten coffins, not to mention any gold, silver and jewelry, and not even a copper plate was picked up.

Lin Du, who was standing in the stone room, suddenly had a flash of inspiration, by the way, it is not strange that the coffin will decay, but in this sealed underground tomb, how can the contents decay so quickly.

There are also a few rusty utensils, which must be caused by the oxidation of the air and the wind, in this case, then this city tomb should not be fully sealed, and it seems that there is a glimmer of hope for going out.

However, it was up to his luck to find those vents, Lin Du walked towards the inner stone chamber on the right-hand side and cursed secretly, Made! Why is it another passage, and now when I see the long passage, there is a shadow in my heart.

But Lin Du walked down and found that this place was indeed very different from the stone chamber structure outside, a cave had appeared in front of him, and as soon as he entered the cave, he was immediately startled by an extremely cold breath.

Lin Du shuddered all over, thinking to himself what the situation was! This castle tomb is so weird, there are only strange phenomena that you can't think of, and it is a place that you feel can't be explained by common sense.

The stone room outside is stuffy, only separated by a stone wall, the stone room here actually exudes a cold and biting cold, and Lin Du also saw an ancient tree about two people surrounded by a large tree, with lush branches and leaves, and it seems to grow quite vigorously.

Lin Du immediately used the spiritual breath in his body to resist the cold, and walked towards the ancient tree, feeling that the closer he got to the ancient tree, the colder it became.

The spiritual breath of the late stage of the third stage of soul refining was indeed strong enough, and it quickly circulated in Lin Du's body for a few days, and his body gradually returned to normal body temperature.

This is a very old tree, as for the name, Lin Du didn't want to study it, when the palm of his hand stroked the ancient trunk, a thin aura entered the palm.

It is indeed because of the nurturing of the aura that this ancient tree can maintain such a lush growth function, and the ancient tree also directly implies the aura, but where is the source of the aura that gave birth to the ancient tree?

Lin Du didn't waste any time, he cultivated first, if he could use the aura of this ancient tree to break through the realm and reach the fourth level of soul refining, then this trip was really not in vain.

Lin Du, who was sitting cross-legged under the ancient tree, ate some dry food to satisfy his hunger, and he didn't dare to drink more water, but he just dipped it a little, and immediately calmed his mind, and after a while, he had entered a state of cultivation.

One day, two days, three days...... It wasn't until the fifth day that Lin Du woke up from his cultivation, and sighed lightly, he still failed to break through to the fourth level of soul refining.

I didn't expect the aura of the ancient tree to be so lacking, in fact, Lin Du also understood that the aura of the ancient tree could continue to cultivate for five days, which was already very rare.

After all, the realm of the late stage of the third level needs a huge aura as an aid to impact the fourth level realm, and at this time, it can be regarded as consolidating the realm of the late stage of the third level, so it should be regarded as a small gain.

Lin Du slowly stood up, five days of cultivation made him look abnormally energetic, but the gurgling sound from his stomach was that he was hungry, and he took out dry food to fill his stomach.

After a while, looking at this ancient tree, Lin Du nodded and said, "Although you didn't meet the requirements I expected, I still want to thank you." As soon as he finished speaking, he slapped his palm on the ancient tree casually.

Bang! The entire ancient tree instantly turned into sawdust, Lin Du couldn't help but be dumbfounded, he didn't use much force, this ancient tree was so unbeaten, how could this be possible.

Lin Du thought at this time, could it be because the ancient tree lost its aura and collapsed, this seems to make sense, but this ancient tree is not a thousand-year-old spirit tree, and it can be felt from the implied thin aura.

This goes back to the question just now, if there are other spiritual sources that are giving birth to ancient trees, then how can you not feel the existence of spiritual energy around you!

Lin Du's eyes suddenly focused on the place where the ancient tree had collapsed, and cleaned up the sawdust on it, only to find that the soil in the center seemed to be a little different from the surrounding ones, so he scraped the soil on it layer by layer, and after half an hour of cleaning layer by layer, he felt that his palms were a little numb.

After a while, his fingers finally touched a hard cold iron object, and a faint spiritual cold qi immediately penetrated into Lin Du's palm and went straight to his body, and Lin Du hurriedly used the spiritual breath in his body to relieve it.

It seems that his guess is right, there is really a spiritual source underneath this ancient tree that is nurturing its growth, but when Lin Du dug out the underground spiritual weapon and presented it in front of him, he couldn't hold back his excitement in his heart......
