After killing the mutant floaters, Xing Feng put his body into his backpack, this guy's corpse is not only valuable, but also like a luxurious luxury, of course, Xing Feng has no collector's habit.

He kept the mutant floater corpse for other purposes, not to sell it back to the city, but to give it to the meat ball.

Swallowing ordinary floaters can evolve the mouthparts of floaters, so what about swallowing this mutant floaters? If he could really get the evolution of mutation by swallowing mutant floaters, then Xing Feng really couldn't imagine the future development potential of Meat Ball.

However, at this time, the meat ball was still asleep, obviously absorbing the floater BOSS, and eating so many ordinary floaters, at this time it was evolving itself through sleep.

Then wait for the meat ball to wake up and then give it to eat the corpse of the mutant floater, and the main thing in front of me is to check the remains of the crypt.

Xing Feng opened the treasure chest guarded by the mutant floaters, and sure enough, he found a remnant map in it, compared with the previous map, it can be perfectly put together, and the second layer of the map in the cave ruins is also available, but there is still a part of the unknown area in the back, obviously, there should be a third layer in this cave ruins.

There was a key next to the remnant map, and after his previous experience, Xing Feng guessed that this key must also be necessary to open the ruins of the second-floor crypt.

In this treasure chest, Xing Feng not only found the map remnants and keys of the crypt ruins, but also a skeleton that was as bright as jade in the treasure chest.

This is supposed to be the spine of a wild monster, one meter long, with a faint white fluorescence in the turquoise color, and it is not ordinary at first glance.

Xing Feng was shocked, picked up this vertebrae, and held it in his hand heavily, much heavier than an iron object of the same volume.

"Materials for crafting weapons!"

Xing Feng's face showed joy, looking at the extremely extraordinary vertebrae like this, if it was used to make a magic staff, and then adding attribute yuan beads to it, the spiritual strength attribute that he wanted to increase would definitely be very considerable!

After all, this is a treasure chest guarded by mutant floaters, and the existence of the map is inevitable, but the existence of this vertebrae is a bit abrupt!

In the treasure chest guarded by the floater boss before, Xing Feng not only found the first map, but also found an intermediate attribute bead, so as a treasure chest guarded by mutant monsters, the value of the items in it must exceed that of the intermediate attribute bead!

Xing Feng put away this vertebra and prepared to take time to rush to Langtian City again, let Blacksmith Wang take a look and estimate the specific value of some of this object!

The second-layer map of the crypt ruins has arrived, and Xing Feng no longer delays, returning the same way, and starting to go deeper into the crypt according to the correct path marked on the map.

Along the way, Xing Feng killed a lot of wild monsters, and the corpses of these wild monsters can be used to exchange for the prestige of Burning Sky City, but Xing Feng is facing a trouble at this time, that is, the backpack space is somewhat insufficient, which has already occupied three-quarters of the time at this time, and there are no points on his body, so it is impossible to upgrade the backpack space!

Moreover, Xing Feng has only walked to the middle of the second layer of the crypt so far, and the number of wild monsters that he wants to hunt in the future will definitely not be small.

I had no choice but to waste some points and choose to consign in the system store!

Consignment items in the system store need to pay a lot of handling fees, a piece of equipment, to deduct 20% of the transaction amount as a handling fee, of course, from the seller's hands.

A piece of equipment is 20% worse, if the number of equipment is more, it won't be sold to death!

As a result, many people are happy to wander around the system store and want to buy the equipment that players are consigning, but few people want to consign it in the system store, even though the market is for all players, but the huge fees are unaffordable.

Therefore, players are willing to waste some time and return to the trading market in the city to trade, after all, there is no additional cost of exploitation of points or money obtained in this way.

Xing Feng had basically not had time to sell the loot obtained from hunting aliens in the plane battlefield before, so he randomly selected a few pieces of equipment that looked good and chose to sell them on consignment in the system store.

The price of Xing Feng's consignment equipment is not low, this is a market for all mankind, and the items sold are all from the alien side, which is a rare equipment on the human side! So as long as the price is not too high, there is no worry that no one will buy it.

After less than five minutes, during which the system prompted Xing Feng to tell Xing Feng that the items he was consigned for sale were sold one by one until they were all sold out.

Through consignment, Xing Feng obtained a total of 18 points, which were enough for Xing Feng to upgrade his backpack space twice, and after the upgrade, Xing Feng's backpack space expanded to 22 cubic meters, which was several times larger than before, and it was enough to hold the items harvested by the group in the crypt ruins!

From the perspective of the hairy corpse, after viewing, the maggot boss's HP is still 83% at this time, and it seems that it will take a long time to kill it.

However, Xing Feng's purpose is not to kill the cave maggot boss, the longer the time drags on, the better, after all, the venom spewed by the cave maggot boss has a very large effect on the attribute improvement of the hairy corpse, very quickly!

At this time, the physical attributes of the hairy corpse have increased by about 20% compared to the beginning, and it can be said that the attribute advantage that the hairy corpse has gradually fallen has risen again, and it has become the number one killer among the puppets controlled by Xing Feng again!

There are more and more floaters on the road, and in the second half of the back passage, the almost narrow passage has almost been blocked by floaters elites, and Xing Feng's travel speed has also been greatly restricted.

For the next whole day, Xing Feng was struggling to walk, and after such a long time, he finally came to the end of the first layer of the crypt ruins.

There is no boss guarding here, but it is separated by a bottomless giant ditch, the giant ditch is nearly thirty meters wide, and there is no rope suspension bridge at all, I think it is up to the player to find a way to pass!

This huge ditch is enough to make the vast majority of players stop here, and the method of relying on the rope to throw it to the opposite bank will not work, and there are no rocks on the opposite bank to fix the rope, which is indeed a very difficult scene.

However, Xing Feng, who saw this scene, his eyes lit up, and his face showed surprise.

Since there will be such a setting in the crypt ruins, it means that there must be a special opportunity on the second or even third floor of the ruins, otherwise it would not be so difficult, at least the scene at this time has changed people, and there is no way to continue walking.

But these are not a problem for Xing Feng at all, Xing Feng's profession is a spiritual master, and he has the ability to control wild monsters as puppets, and Xing Feng is also very lucky, controlling a flying snake in the plane battlefield.

With the gliding ability of a flying snake, will Xing Feng still be trapped by the giant ditch in front of him?

So Xing Feng directly summoned the flying snake puppet, rode up, and easily crossed the giant pit to the opposite bank.

There was no strange existence on the other side, but there was an iron gate that was almost the same as before, Xing Feng stepped forward and opened the iron door with a key.

The moment the iron door opened, a wave of heat suddenly hit his face, Xing Feng subconsciously covered his face with his arm, and only after getting used to it a little bit did he take his arm away and frown slightly.

Inside the iron gate, there was a fiery shijie, red, and swept by bursts of flame storms, which was extremely shocking to watch.

Xing Feng hesitated slightly, switched the perspective to the hairy corpse, and checked, the health bar of the cave maggot boss was still 42%, and after measuring, Xing Feng still didn't summon the hairy corpse.

Fighting against the maggot boss is an extremely rare way to improve attributes, Xing Feng didn't want to waste this opportunity, so he decided to let the hairy corpse continue to improve, in this sea of fire, even if there is no hairy corpse to help, he can be completely careful, if he encounters unbeatable trouble, Xing Feng has the confidence to successfully retreat.

After making up his mind, Xing Feng decided to be careful and explore the second layer of this crypt ruins.

After entering this sea of fire, the originally gloomy cave was completely replaced by the bright fire, walking on the second floor of the crypt ruins, always be careful of your feet, most of the cracks on the ground, if you don't pay attention, it is still a trivial matter to be tripped, but if you fall into the gaps, it is definitely a fairy to save!

There was golden-red magma flowing in the cracks, and Xing Feng on the ground felt a burst of hot feeling, let alone falling into the magma!

From Xing Feng's point of view as a reincarnation, this place is absolutely extraordinary, at least in terms of his current strength, he should not be able to play the second layer map of this crypt, but Xing Feng also has some hole cards, in line with the idea that even if he can't sweep the second layer of the crypt ruins, he has to find out, Xing Feng walked out of a distance, and finally met the first wild monster in the crypt ruins.

A whole body is red, like a soul wandering in the world, without legs, and the lower body is just a vague phantus, appearing in Xing Feng's sight.

Xing Feng was shocked, before reincarnation, although Xing Feng had never been to this crypt ruins, he had heard of this wild monster. Moreover, Xing Feng has also encountered the advanced form of this wild monster, so it can be said that he still knows this wild monster very well.

This is the 'Flame Ethereal', a fourth-order primary creature.

According to the method of distinguishing the strength of wild monsters, the fourth-order wild monsters are equivalent to the strength of the player's comprehensive attributes reaching 40 points.

Xing Feng was invincible in the plane battlefield, and his spiritual strength at that time was only more than forty points, which showed how strong the strength of the fourth-order wild monsters would be!

Another point is that although the fourth-order monster is equivalent to a player's comprehensive attribute of 40 points, which seems to be one-sided, this shows that it is a player's comprehensive attribute.

How far can a player with 40 stats reach? Maybe this is not more than too much explanation, of course, it also involves some skills, battle prediction ability and other factors, so it is difficult to make an evaluation.

But Rao is like this, and it's not something Xing Feng wants to face.
