With Lin Yuan's current strength, even if he was lying down and sleeping in the monster's lair, he would not worry about any danger to his life.

This can be seen when Lin Yuan learned the sword technique of returning to the ruins and immersed himself in the sword intent.

Whether it is a spell attack or a physical attack, it is not enough to break through Lin Yuan's defense, after defeating the human-faced snake mother, updating a wave of equipment and skills, and making up for the final poison resistance shortcomings, the monsters here are no threat to Lin Yuan.

Therefore, even if the taunting gold coin locked the hatred of all the monsters around the ten kilometers on Lin Yuan's body, he was not moved, this was not ignorance, he did not know the power of the overwhelming monsters, but out of a kind of confidence in his own strength.

Soon, the first wave of monsters closest to the monster lair arrived.

In the face of this swarm of monsters, Lin Yuan did not use thunder to destroy them at the first time, but stood in place with the blade of the end of the world in his left hand and the sword of the ruins in his right hand, killing the monsters that rushed one by one.

Every time he took out his sword, Lin Yuan used the least strength, and sometimes even did not use any force, taking advantage of the situation, so that the enemy could kill each other.

In addition to saving as much effort as possible in the attack process, Lin Yuan also dodged the spells or poisons released by the monsters as much as possible, unless he really couldn't dodge, so he resisted with his own defense.

Although these monsters are not a threat to Lin Yuan, some additional effects of their skills will eventually have a subtle impact on Lin Yuan, causing him to consume additional physical strength to fight, and in group battles, the most taboo thing is to waste physical strength.

Surrounded by enemies, you don't know if there are any stronger ones among them that haven't yet appeared, or how many enemies there are.

In this case, only by conserving physical strength as much as possible and consuming the enemy's strength can it be possible to achieve the final victory, and at the same time, conserving physical strength is not only for the final victory, but also to deal with some unexpected situations on the battlefield, and it is likely to be able to save one's life at a critical moment.

Only by being careful enough can you live long enough in the midst of the crisis-ridden battlefield, this is the valuable experience that Lin Yuan has summed up from his many years of life experience, and he has practiced it.

Out of the sword, in the sword, in the sword....

The mechanical action has lasted for an unknown amount of time, even the human-faced snake mother emperor has been killed twice by Lin Yuan, and the number of monsters who have poured into the fortieth layer of the monster lair has not decreased, and they still maintain their strong attack power, and continue to attack Lin Yuan.

The mana and qi have long been exhausted, and the brute cow potion that can restore physical strength has already been taken, and even the effect of upgrading and restoring physical strength has been maximized by Lin Yuan, but the continuous battles for such a long time still made Lin Yuan's state slip to the bottom.

There was not much physical strength left, and there was a faint pain in the muscles and bones of his body, but Lin Yuan's mind did not fluctuate in the slightest, and he still steadily took out his sword, collected his sword, and killed the monsters that were constantly rushing towards him.

In his previous life, there were more dangerous and more difficult battles, Lin Yuan had experienced them, compared to the dangerous places where he could die at any time, the battle that was going on in front of him at this moment was just a pediatric for him.

After killing another batch of monsters, Lin Yuan finally showed a smile on his face, and the underground space no longer vibrate, which means that the number of monsters that are still pouring here is no longer much.

This also means that Lin Yuan's battle, which lasted for more than two days, is finally coming to an end.

Time flowed forward for another hour, Lin Yuan condensed the mana that had just recovered in his body, smashed it down with a thunderstorm technique, and the last batch of monsters in front of him were killed by flashing thunder in the sky, and after waiting for a long time, he didn't see any new monsters coming in.

It was only at this time that Lin Yuan was convinced that this battle was finally over.

The battle for two consecutive days really made Lin Yuan extremely tired.

However, such hard work is also worth it, not to mention that Lin Yuan's personal level has been raised to level 41, and the human-faced snake suit has been gathered to five, and the number of various equipment in Lin Yuan's equipment column at this moment has also exceeded a thousand, and he has also obtained a large number of star coins.

As well as more than a dozen white, blue-and-white skill books, and more than thirty precious materials that can be used for refining medicine or alchemy.

After packing up all his loot, Lin Yuan was not too dirty, as soon as he sat on the ground, he took out food and water and ate and drank, and before he was full, Lin Yuan found that the image of the purple gold coin imprinted on his palm was glowing.

It was a taunt gold coin, and after pulling enough monsters for Lin Yuan before, it turned into a tattoo and imprinted on Lin Yuan's palm.

At this time, Lin Yuan suddenly remembered that in the previous introduction to the taunt gold coin, if you can kill all the targets attracted by the taunt of this gold coin, you can get a mysterious reward.

"I don't know if there are any surprises in this mysterious reward. Lin Yuan thought optimistically while gobbling it up.

When the light of the taunting gold coin tattoo was condensed to the maximum, it suddenly dissipated, and then Lin Yuan's palm had an extra piece of paper, and the tattoo of the taunting gold coin completely disappeared.

"This is the mysterious reward given by the taunt gold coin?" Lin Yuan stuffed the last piece of bread in his hand into his mouth, took out a ham sausage, and while eating, he checked the item information of the paper in his hand.

Name: The only invitation to the Silent Deep Sea

Quality: Purple

Description: Using this invitation, you can open the Silent Deep Sea Secret Realm, after the secret realm is opened, you can enter a team of up to five people, and the secret realm will be closed after clearing the level.

The only secret invitation, this is a treasure!

No matter what the only secret realm is, no matter how high or low the difficulty is, as long as you can clear the only secret realm, you will definitely be able to obtain some ultra-rare technology, or a certain material that has been out of print, and even some unique secret realms, there are super opportunities for people to become gods.

The above three kinds of harvests, no matter what they are, are things that can change a person's fate.

Even in the future, three hundred years later, the only secret realm invitation is an extremely rare thing, and every invitation that circulates on the market will be auctioned for a sky-high price, which shows how rare it is.

Recalling the rare and only secret realm clearance experience in his previous life, Lin Yuan couldn't help but laugh, it was a super harvest that made him, the future human guardian god, unable to calm his mind.

In a good mood, Lin Yuan felt that the fatigue he had been fighting for several days seemed to have disappeared a lot, and with a great appetite, he actually ate twice as much food as usual, and then dug a pit and buried himself on the spot, and slept contentedly.
