Yu Xiao entered a long and narrow passage at this time, and walked down the dark staircase inside.

He had just been searching on the fifth floor of the King's Tomb, and finally found a special passage, and then entered it.

There are many traps arranged in the passage, Yu Xiao carefully dodge, and he was almost killed when he just came in, but fortunately he used teleportation relatively quickly.

The mechanisms here are all very dangerous nirvana, if they are triggered, they will be easily killed, Yu Xiao has to be careful, and he doesn't dare to be careless.

Yu Xiao has seen the power of the mechanism, and a crossbow arrow shot casually is powerful and powerful, and it comes with poison, just looking at it makes me feel terrifying, and Yu Xiao asked himself if he dared not try it easily.

An eerie cold wind blows from inside the passage, which is terrifying.

Yu Xiao walked to the end of the passage, there was no road ahead, only a big puddle remained.

Presumably, the real tomb of the king is under the water!

Yu Xiao jumped into the puddle without any hesitation, dived into the water, and swam inside. Although Yu Xiao has become an undead, an unformed undead like him still needs to breathe, so he has a limited amount of time to stay underwater, and he must quickly find the entrance to the King's Tomb.

I saw that this was a closed waterway, with smooth stone walls up and down, left and right, and the black forest in front of me was not clear at all.

Yu Xiao dived all the way, but the speed was not fast, in case he encountered any monsters, he would have time to deal with it.

At this moment, Yu Xiao suddenly felt that the stone wall on the left side was a little strange, and he was shocked, it was a mechanism.

I saw that the stone wall on the left suddenly revealed two black sharp arrow tips.

Whoosh, two arrows carried a series of bubbles and shot towards Yu Xiao.

Yu Xiao rolled in the water, turned his head sideways, and two arrows grazed Xiao on the cheek and chest respectively, and was almost hit in the head and heart, but fortunately he reacted quickly.

Two arrows were nailed into the stone wall.

After this incident, Yu Xiao became more cautious.

Diving deep along the narrow waterway, his eyes inadvertently swept over the wall on the right side of the waterway, and Yu Xiao suddenly found that there were some strange things on the wall next to the underground waterway, leaving some scratches and strange marks, leaving a series of special formations on it.

Yu Xiao felt that the strange formation pattern was somewhat familiar, and after looking at it for a while, he saw that the special feature of the formation pattern was exactly what he showed when he used the undead to summon it.

Could it be that this tomb of the king is still related to the bloodline of the Lord of the Undead? Yu Xiao couldn't help but think in his heart.

This is not the time to think about this, there is a feeling of suffocation in the abdomen, the time to hold his breath in the water has reached the limit, he must quickly find the entrance, and look for the wall, except for some subtle cracks, the wall is as smooth as a mirror, and there is no flaw to be found.

Could it be that I am thinking too much?

Yu Xiao always felt that the appearance of an undead summoned formation here should not be so simple.

He continued to expand his search, reaching into a corner beneath the stone wall.

Yu Xiao's hand touched the five fingerprints, and his heart jumped inexplicably, these five fingerprints were very light, even if he touched them, if he didn't pay attention, he might miss them.

Maybe there's some mystery to these five fingerprints!

Putting the five fingers of his right hand on these five fingerprints, Yu Xiao slowly pressed down and pushed these five fingerprints in.

A stone slab about an arm's length away slowly cocked.

There is a hidden grid on this wall, and the mechanism of the hidden grid is set up very hidden, and if you don't search the wall for a long time, you can't find the mechanism here.

The moment the dark grid on the wall was opened, a beam of colorful and gorgeous light bloomed in the darkness, Nie Yan looked into the dark grid, the bright light illuminated him dizzy, looking inside, the dark grid was a mess, there are many things that should have been lost, but there are still many things that have been preserved, all of them are some special gems and other things.

Yu Xiao collected these gems and counted them carefully, there were five first-level attack gems, three second-level life gems, and one third-level magic gem.

Gems of the first and second grades can still be bought in the auction house, but it is difficult to say for the gems above the third grade, after all, there is no one in the market to sell such things. If you let the gem craftsman set it on the equipment, the attributes that can increase the equipment are undoubtedly the highest, of course, this is only among the gems that Yu Xiao has obtained so far, I heard that there will be gems above level five in the future.

Find a gem tinkerer to create a groove in the equipment for two gold coins, and some equipment itself has additional grooves, such as the Star Scar Staff in Yu Xiao's backpack, so the Star Scar Staff can have two more grooves than other equipment.

The number of grooves that can be obtained is different depending on the level of equipment.

Spiritual weapon-level equipment can have one groove, and Hallow-level equipment can have three grooves, and then go up, and then increase in order.

Punch out the groove and spend three more gold coins to inlay the gem into it, inlay a first-level gem can increase the corresponding attribute by 5 points, and inlay a fifth-level gem can increase the relative attribute by 25 points.

Due to the huge role of high-level gemstones, each team almost rushed to ask for them, but the yield was extremely low, so there was basically no price in the market, and it was impossible to buy them at all.

At present, there are only first-class and second-class gemstones on the market, but many people still rush to buy them.

Yu Xiao's equipment could have been made to create grooves and inlaid gems a long time ago, but he didn't do that, because after the equipment is inlaid with gems, it cannot be taken out, that is to say, after all the grooves that you can have in your equipment are inlaid, even if you encounter high-level gems in the future, you can't replace them.

However, getting these gems still made Yu Xiao very excited. After all, for now, the price of these low-grade gems is ridiculously expensive, which is one of the reasons why Yu Xiao did not set gems into his equipment.

Putting all the gems into the backpack, Yu Xiao searched the dark grid again to confirm that there was no omission, and then closed the dark grid back and swam inside.

He has little time left to stay underwater now, and if he doesn't hurry up, he will have to drown in the water, and then his glorious killing god will die a little unjustly.

"Next time I come out, I will definitely go to the grocery store and buy some water-repellent beads!!" Yu Xiao said secretly in his heart.

After swimming in the narrow waterway for a few minutes, Yu Xiao finally saw a glimmer of light above, so he went upstream and poked out of the water.

In front of it is an incomparably large and huge space, which can accommodate hundreds of people, and in the center is a dark gold coffin, about five meters long, two meters wide, and two meters high, covered with sculptures, and all kinds of delicate formations are everywhere.

Except for this dark gold coffin, there was nothing here.

There didn't seem to be any monsters here, so Yu Xiao jumped up from the water and walked towards the huge dark gold coffin.

Yu Xiao is almost certain that this is the real tomb of the king, and it should be the ...... lying in the coffin
