As far as Lu Zhong knows, the things that are Dao are thousands of years old.

Lu Zhong is not sure that in modern times, this information has not changed, and there is really a lonely ghost in this world.

However, in Lu Chong's mind, even if there is such a thing as a ghost in the current society, it does not dare to have too much intersection with the living. It is important to know that the ghost of the Dao is a kind of void energy body, and it is yin in nature, and the living person, whether it is a man or a woman, has a strong breath of life or yang energy on its body. Although there is a saying that yin and yang attract each other in this heaven and earth, there is also the truth that yin and yang are mutually restrictive. If this ghost really intersects too much with the living, it is undoubtedly committing suicide in a chronic manner.

Except, of course, for ghosts who are guarded or cultivated by strange treasures!

Although Lu Zhong couldn't be sure that there were lonely souls and wild ghosts in the Second Attached Hospital, a place like the hospital was also a place where life and death were controlled, and there was naturally yin qi gathered over. And the longer the hospital is open, the more Yin Qi will gather. Naturally, a large amount of free soul energy will also accumulate here.

And these free soul energies do not have a master, but they are the real goal of Lu Chong's coming over this time.

The night was dark, and under the dim light of the street lamps, there seemed to be fog or cold air flowing around.

Lu Zhong spied unhurriedly in the hospital's garden, pond, rockery and other places.

Because Lu Chongzhi said that if there was really a ghost in the hospital, or if the ghost was conscious, it would definitely choose a place with the strongest yin qi to stay temporarily, so as to avoid the invasion of the blazing sun during the day.

The pond and rockery of the hospital are the best places for ghosts to stay.

The small artificial pond in the hospital is not large and is very long. The water here is sourceless and lifeless.

Lu Chong can now see at night, and he can even clearly see that the water in this pond is extremely turbid.

Walking around the artificial pond twice, I can sense that there is indeed a lot of yin qi gathered here. And there was a faint amount of free soul energy flowing around him.

Lu Zhong mobilized a trace of soul energy in his body to come out, and did not take the initiative to control it, allowing it to flow freely with those free soul energy in the air.

Under Lu Chong's induction, this trace of his soul energy was out of his control, but it was converging under a bridge in the artificial pond with other free energy.

"Where is it?" Lu Zhongzhong moved, but he quietly walked to the small bridge, and immediately opened his [Microscopic Yin and Yang Eyes].

Suddenly, in Lu Chong's eyes, there was a scene that could not be seen by the naked eye.

A large amount of free soul energy and yin qi began to burrow into a small hole under the small bridge.

This small hole is the size of a rat's hole, and it stretches for three or four meters in a zigzag, forming a pocket-sized passage with nine twists and eighteen bends.

There are no ghosts in the innermost part of this pocket-shaped passage, but there are three small black stones the size of a pinky.

The yin qi and free soul energy around him were converging towards the three small black stones.

"Gathering Yin Soul Stone!" Lu Chong was slightly moved, and there was a sudden surprise in his heart.

This Yin Gathering Soul Stone is a gemstone that can condense the Yin Qi on its own and collect the free soul energy. This thing, which was everywhere before the age of the gods, was simply dispensable to those supernatural powers. Even some real ghost cultivators can't look down on it.

However, this kind of [Gathering Yin Soul Stone] is quite beneficial to the newly born ghosts. As long as the newborn Yin Soul stays in its vicinity, this thing can help the newborn Yin Soul stabilize the Three Souls and Seven Spirits, so that they will not be scattered under the contact of the blazing sun and fire of the outside world. It can even help the newborn Yin Soul to cultivate unconsciously. And the best effect of [Gathering Yin Soul Stone] is that it can help Yin Soul walk freely in the daytime...,

In the ancient or god-sealing era, where would those immortals and great supernatural powers put the Yin Soul who could barely cultivate in their eyes? Naturally, they didn't look down on the [Gathering Yin Soul Stone].

But the current earth's aura is thin, and it is very different from the situation in the ancient and god-like eras. This thing can also be considered a treasure.

What's more, from Lu Yue's memory, I know that this [Soul Eater Worm] also needs to eat, and their favorite food in ancient times is this [Gathering Yin Soul Stone].

As far as Lu Zhong knew, these three small [Gathering Yin Soul Stones] could allow the [Soul Eater] mother worm to advance to LV2 level, and after the mother worm was promoted to LV2 level, it had the ability to make all 100 [Soul Eater] subworms under its control advance to L1 level!

"It seems that my luck is good!" Lu Zhong smiled slightly, and closed the [Microscopic Yin and Yang Eyes] in a moment's time, and by the way, released the mother worm of the [Soul Eater Insect] from the [Plague God Bead].

Although it is also possible to take the [Soul Eater] mother worm into the body, however, Lu Chong is a little unaccustomed to it for the time being, and the [Plague God Bead] has great benefits for insects, these days, when the [Soul Eater Worm] is not dispatched, it is placed in the internal space of the Plague God Bead by Lu Chong.

As soon as she came out, the mother worm of the Soul Eater sensed something, and couldn't help but crawl around in Lu Chong's palm with joy, then spread her thin wings, turned into a streamer, and rushed under the bridge, and quickly drilled into the small hole.

Soon, the little thing landed near the three [Gathering Yin Soul Stones], spreading its wings and singing softly with joy.

The [Soul Eater] mother worm stretched out its long and narrow mouthparts and kept gnawing on one of the [Gathering Yin Soul Stones], fearing that others would snatch it, and it even instinctively stretched out its thin wings to wrap around this [Gathering Yin Soul Stone].

Seeing the excitement of this little thing, Lu Zhong hurriedly used his soul to remind it: "Little guy, you are allowed to eat one first." The other two landed here for the time being. And you try to use these two [Gathering Yin Soul Stones] to absorb the soul energy that is free between heaven and earth during this time!"

"Squeak...... Squeak ......" The Soul Eater mother chirped softly twice in agreement. In fact, it is not weak in intelligence, and it also knows the truth of the long stream. It is also known that Lu Dao uses the [Gathering Yin Soul Stone] to maximize his profits.

Lu Zhong arranged the mother worm of the [Soul Eater Insect] here, and he was not worried about the safety of the [Soul Eater Insect] mother worm. Don't look at the small body of this female worm, and it is only LV1 level strength, but, in modern society, there are really not too many things that can threaten its life.

The mother worm of the [Soul Eater] is faster than its offspring, and the anesthetic toxin of its tail needle is also more powerful, and it even has a certain ability to attack souls.

In modern society, all kinds of supernatural creatures have long disappeared. Even if there were, it was pitiful. They are generally far removed from the human sphere. And the Soul Eater was now in that cavern beneath the ground, and there were even fewer things that could threaten it.

Under Lu Chong's calculations, he knew that the Dao Soul Eater Worm was definitely the best place to settle in this small cave.

With the presence of the [Gathering Yin Soul Stone], the free soul energy continuously generated by the entire hospital will continue to enter that small cave and be absorbed by the [Soul Eater] mother worm. Lu Zhong only needed to come over once a week, and absorbing the soul energy refined by the [Soul Eater] mother worm would allow his strength to grow steadily.

According to this situation, Lu Zhong has become a parasite!

Thinking of this situation, Lu Chong also smiled, it doesn't matter if he becomes a parasite or not, the key is that his strength can improve steadily!

After arranging the [Soul Eater] female worm, Lu Zhong was going to go to the oncology department of this hospital again before returning to school.

But at this moment, he suddenly felt an extremely strong coldness rushing through him, and then, he sensed the anger of the [Soul Eater] mother worm......
