"I opened a hydrotherapy technique for the mage water system." Li Shisi's words saved Ye Chen a lot of trouble, after all, this skill book of the mage's hydrotherapy technique is now the most sought-after in the safe zone, and it is even more sought-after than the mage's summoning system.

In an entire bookstore, there are only about two hydrotherapy books a day, but they often don't show up in the consignment shop because no one sells them.

At the beginning of the apocalypse, no one needed this skill, and this hydrotherapy technique was also regarded by all the power sects as the most urgently needed skill book at present, for only one reason, because it could add blood, and for such a reason, it greatly ensured the combat endurance and safety guarantee, which was incomparable.

Now that he has actually typed out this book by himself, this is naturally very good, and Ye Chen knows that the hydrotherapy technique of the bronze level is much better than the black iron level treatment effect in the bookstore, and in general, this is a treasure book of great strategic value.

You put this away, and after you go back to the city and change jobs, I'll buy you a fourth skill slot, and you can learn it.

"This, is this really good, such a valuable skill book is really for me to learn?"

"Nonsense, I don't want you to learn it from anyone, my minions will need you as a super milk-mom in the future." Ye Chen said unceremoniously.

"You're the granny, your whole family." The problem girl was almost annoyed, but she couldn't help but have a hint of sweetness in her heart.

Ye Chen obviously didn't have time to speculate on the girl's thoughts, and the two of them rested in place for about two hours, waiting until the blood volume of all the summoned creatures had recovered to full value, and then continued to move towards the deepest tunnel.

Then, after passing the previous big level, there are several waves of monsters below, and there is no greater threat.

Ye Chen had an idea, and he used the taming fruit on the way, and even subdued two more Demon Land Blood Bats, which made the comprehensive strength of his summoned biota group soar again.

With the absorption of the health of the two Demon Land Blood Bats, and then the feedback to add blood to the Bone Demon, the Bone Demon Heavy Shield Striker created by Ye Chen's center of gravity can be said to have stronger survivability, although the two Demon Land Blood Bat can only bring two health points per second to the Bone Demon, but with the high defense of the Bone Demon, this is enough to ensure that when killing the average monster group, its health value has not been reduced much.

Just as Ye Chen had killed the dozen or so monsters in the last wave of the tunnel, suddenly, one of the many old torches inserted on the pit wall caught his attention.

Because he suddenly found out that the torch was actually extinguished?

On the walls on both sides of the entire tunnel, there are two old torches on the left and right almost every tens of meters, although their existence cannot bring excellent vision to the transferee, but at least it is not black, but why is this torch different from the other?

This discovery made Ye Chen walk over and try to receive the torch in his hand with the pick-up command, but it turned out to be successful.

Torch of Deception (Special Living Item)

Life: Permanent

Attribute: +3 Illuminate Radius

Trait: Units other than allied units cannot share the illuminated vision provided by torches.

……

"I'm X, good thing." When Ye Chen got the details of this torch, he couldn't help but be pleasantly surprised.

"Isn't it just a torch, and you can buy a bundle of copper coins." Li Shisi didn't know why she came over and said, but when she saw the attributes of the torch, she knew that she was wrong.

"That's the benefit of entering the monster's lair dungeon for the first time, the good things are basically taken by the people who enter the dungeon for the first time, unless these people are not careful enough, just like you." Ye Chen was in a good mood.

"Why bother with people, but this torch is really a good thing, it is permanently lit, and the illumination range is three times that of an ordinary torch."

"Wrong, its most valuable thing is its characteristics, we can only share the vision it provides, but outsiders cannot, this is something that ordinary torches can never do, if I am asked to estimate, this special equipment for life alone is worth more than 10,000 copper coins." Ye Chen said with a smile.

"Is that an exaggeration?"

"It's all underestimated, imagine that at night in the wild, our vision is bright and sufficient, while others are dark, what will happen to this scene?"

Ye Chen explained the usefulness of this fraudulent torch, and he couldn't wait to equip it to his life equipment slot.

There are fifteen combat equipment slots, one place for special item equipment slot amulets, and three for life item equipment slots.

One of the special equipment columns of life, there is always a lack of lighting items, and most people will be equipped with candles, torches, or higher-level oil lamps, night pearls, etc., because this can always ensure that they have a certain vision advantage at night.

And this torch illuminates +3, simply put, it illuminates a range of thirty meters, which is twenty meters more than an ordinary torch, and it is directly not inferior to the current highest-grade night pearl.

Sure enough, when Ye Chen equipped it to the living equipment position, replacing the original ordinary torch, the vision of the two of them in the dark pit suddenly spread, and they could finally see the entrance of a huge lair in front of them from a distance.

"My mother, what kind of monster is that, it's so huge, it's much stronger than the door god." With a sufficient field of vision, Li Shisi suddenly saw a large humanoid creature in the depths of the nest, sitting on a big chair at the innermost part of the nest, munching on chicken legs.

This monster is estimated from the fact that it is more than two meters tall when it sits, it is definitely a behemoth with a height of more than five meters, and several bonfires are lit around it, and a large number of Shanhu monsters are having a bonfire dinner, and they are eating very happily.

And the food of these Hushan tribes, among them is mountain and forest beasts, fierce creatures, and even living corpses and humans.

"Gross." Li Shisi couldn't help but vomit on the spot.

"Slowly get used to it, otherwise it will be difficult for you to survive in the last calamity, and if you follow behind, I will blame you." Compared to Li Shisi, Ye Chen was obviously not much moved, after all, he had already adapted to these after more than a month of experience in his previous life.

"Bone Demon, give it to me, kill!"

This time, Ye Chen did not hesitate, even if it was the ultimate boss of this monster's lair, the ancestor of the Hushan clan, the strength of the silver rank.

Now with the assistance of the two Demon Land Blood Bats to regenerate blood, it is obvious that Ye Chen's summon biomass combat has continued to be greatly strengthened.

The bone demon received Ye Chen's order and rushed forward as soon as possible, and Ye Chen himself did not lag behind, because he had to go to the front line, otherwise the shadow guard's ten-meter range would be limited to the shadow guard's attack.

"Rolling Stone Bombing." For the first time, Ye Chen lured most of the monsters in the lair to the entrance, and then the door god used its devastating skill.

The next moment, a stone ball with a diameter of up to a meter from the pit with unparalleled momentum rolled violently into a large group of monsters in the lair.

Li Shisi clearly saw that these monsters, whether they were Hushan warriors or dark archers, or mountain beasts and split-tooth demon dogs, etc., all rose up row after row of damage.

“－100－100－100－100－100－100－100－100－100－100………”

But the stone ball's rolling attack was not finished, as it rolled into the center of the monster pack in a straight line, and then exploded violently.

A large number of stones exploded and splashed violently, and then Li Shisi saw a terrifying scene again, only to see that the damage of most of the monsters in the nest went crazy.

"-50-50-50-50-50-50-50-50-50......" round of rolling stone bombardment, directly causing one monster after another to fall.

In less than a few seconds, most of the monsters in the original lair were more than fifty units, but most of them were bombarded by the rolling stone of the door god.

Those who can still stand and fight, in the end, there are only a few mountain beasts and Hushan warriors, and two Hushan dark archers who are outnumbered, and the amount of blood is either half blood or residual blood.

A large number of Hushan Clan Dark Archers, Split-Tooth Demon Dogs, and Demon Land Blood Bats, all hated on the spot under the devastating bombardment-level skill of the Door God.

Astound!

This turned out to be the true terrifying strength of the Stone Ball Lord!

At this moment, Li Shisi finally understood why Ye Chen had taken a great risk to keep this Stone Ball Lord at the end, and use the domesticated fruit to tame it at any cost.
