This tomb gate is six meters high and three meters wide, and it is made of some kind of cyan stone, and some mysterious images and runes are carved on it, and the atmosphere is ancient, and I don't know how many years it has existed.

In the center of the tomb door, there is a hole the size of a water tank, and the purple poisonous mist is constantly wafting out of it, poisoning the surrounding plants and monsters.

In the open space around the tomb gate, a large number of bones were piled up, including several human bones, from which it can be inferred that they wanted to open the tomb door and enter the inside to hunt for treasure, but they were poisoned by the poisonous gas floating from inside, and they did not even have time to escape.

Now Li Feng and the poisonous gas they saw was diluted for a long time, the concentration was not large, and the toxicity had weakened a lot, if it was the poisonous gas when the tomb door was just broken, they would have hung it up a long time ago.

Judging from these bones, the monsters that died here were very strong, and even they were killed instantly, so you can imagine how terrifying the poisonous gas was at that time.

Li Feng and Feng Wushuang Ling searched carefully around, but they didn't find any medicinal materials, and the nearby plants were all withered, and they didn't have the power to resist this poison.

Seeing that the layers of highly toxic states on their bodies are getting more and more, if they don't find a solution, they will really have to kneel.

The strange thing is that this kind of highly poisonous character will not be eliminated when it dies, and it naturally exists for five hours, I am afraid that it is at least a top-quality toxin, and it also has a special nature, even a top-level antidote cannot be removed, and a specific antidote needs to be used.

"The poison is escaping from inside this tomb gate, let's go in and take a look. Maybe a cure can be found. Feng Wu Shuangling proposed.

Li Feng nodded. said: "There is a possibility. In addition, these powerful monsters and adventurers want to enter this ancient tomb, and there may be treasures inside, but the poisonous fog inside must be very thick, and we cannot guarantee that the health value will be recovered in time. ”

This poisonous mist is very powerful, and it can't be resisted with god-level flames, and I don't know what it is released, which is extremely terrifying.

"How can you find treasures without risking your chances. You hurry up and develop a top-level poison resistance to weaken the toxicity of this poisonous mist. Feng Wushuang Ling said.

"That's the only way, I hope I can get something from going in, don't run in vain." Li Feng said helplessly, and began to refine the top-level poison resistance agent, although this poisonous mist is extremely powerful, but in the final analysis, it is still a poison attribute attack, and the poison resistance attribute can weaken the effect of this poisonous mist.

In Master Poison Xi's alchemy notes, the recipe for the top poison resistance agent was recorded, and Li Feng prepared the medicinal materials. said to Feng Wu Shuangling, "Aren't you coming to help?" ”

Feng Wushuangling's eyes flashed, and she sat opposite Li Feng. By joining forces, the two of them can increase the refining power of top-grade potions and reduce the refining time.

Half an hour later, two top-grade poison resistants were refined, they were about the size of a fingernail, black in color, and the surface was very rounded, like two black pearls.

[Top Poison Resistance] Top Elixir, after taking it, Poison Resistance +1000, Poison Attribute Damage Reduction by 30%, immunity to poison attacks below the top level, duration for 60 minutes, cooldown time 5 hours.

"Senior Sister Shuangling, the medicinal materials for refining top-grade poison resistance agents are all prepared by me, if you want to use them, you need to bear half of the material cost, and exchange ten high-grade potions." Li Feng said.

"It's stingy!" Feng Wushuang Ling snorted coldly, took out a batch of high-grade medicinal materials and traded with Li Feng.

Li Feng smiled and said, "My brother still settles the account, you are just my senior sister, and you have not reached the point where you can use it for free." ”

"To what extent does it have to be free to use?" Feng Wu Shuangling suddenly asked.

"Of course, you have to be my closest person, you know, even my stupid apprentice doesn't have the treatment of using my potions for free." Li Feng said.

Feng Wushuang Ling snorted coldly, took the top poison resistance, and walked towards the cyan tomb gate, Li Feng also used the medicine,

The edge of the big hole in the center of the tomb door is very neat, it should have been blasted open by some powerful magic, and the existence that can send out this kind of attack is extremely strong, and I don't know if I have entered this ancient tomb.

This hole is the size of a water tank, which can be passed through, Li Feng and Feng Wushuang Ling drilled into the ancient tomb, it was very dim, the cold wind gusted, and some strange sounds came out, it was a very terrifying place.

Feng Wu Shuangling wanted to turn on the Fire Phoenix Divine Flame to illuminate, but was stopped by Li Feng, "Lighting up your body in this kind of place is simply self-defeating, I have a high-grade eye-catching potion here, you can see things in the dark, take it and use it." ”

"More money?" Feng Wushuang Ling asked.

"Damn, no money!" Li Feng said.

"What do you mean, didn't you just say that you have to be your closest person to use your potion for free?" Feng Wushuang Ling said coldly.

"Damn, my kindness has become a donkey's liver and lungs in you, since you like to pay so much, then it's better to pay double." Li Feng said depressedly.

"You said it's free, so I won't spend this unjust money." Feng Wu Shuangling directly took the high-grade eye-catching elixir in Li Feng's hand and used it, and walked inside with the Ziyan Phoenix Blood Sword.

Li Feng shrugged his shoulders and walked next to Feng Wu Shuangling, and when he came in from the tomb gate, there was a huge tomb road, and the entire passage was made of bluestone, which was very solid.

There was a damp and rotten smell in the air, there were many broken bones on the ground, some luminite stones were inlaid in the walls of the tomb, emitting some dim light, and the whole environment was lifeless, and there was not a single living thing in sight.

The further they went, the thicker the purple poisonous mist became, and Li Feng and the others had taken top-level poison resistance, and the blood was still relatively fast, but it was finally not to the point of being unbearable.

"Squeak!" Suddenly, from the depths of the tomb, a large number of vampire bats flew in, these bats were the size of a basin, with sharp fangs, red eyes and red lights, and on their backs, all of them were elite monsters of 70.

As soon as these vampire bats came over, they continued to fly around Li Feng and Feng Wushuangling, and the fangs in their mouths emitted blood, exerting a bloodsucking state on the two people, causing the blood volume of the two people to drop very quickly.

Without any nonsense, Li Feng and Feng Wushuang Ling each turned on the god-level flames and launched a fierce attack on these vampire bats, and under the scorching flames, a large number of vampire bats were killed in seconds, and the corpses fell to the ground.

However, the number of these vampire bats is very large, they have killed hundreds, and the number of vampire bats has not decreased, so they don't know when they want to kill, so they simply turn on the top-level concealment effect and avoid these vampire bats.

The two of them walked all the way along the tomb to the inside, the space here is very large, and there are bones of living beings everywhere, most of them are broken, I am afraid that they have experienced a tragic battle in their lives.

After walking for more than half an hour, the two of them came to a huge hemispherical tomb, and the bones inside were piled up, and there were even giant bones among them, but because time had passed, these bones had long since decayed, otherwise they could be picked up as epic materials.

Li Feng noticed that in the center of the tomb, there was an earthen cave with a diameter of two meters, and the purple poisonous mist was emitted from it, and around the earthen cave, some purple grass grew, and the purple light flashed on the surface, which looked very beautiful.

These purple grasses still grow so well under the influence of purple poisonous mist, showing that they are extraordinary.

"Senior Brother Snow Night, could those purple flowers be the antidote?" Feng Wushuang Ling asked.

"It may be an antidote, or it may be a stronger poison...... Li Feng's eyes flashed, he opened the abyss demon fire shield, and walked towards the earth cave, Feng Wushuang Ling was on guard beside him, and the purple flame and phoenix blood sword in his hand lit up to prevent a monster from sneaking up.

This time it was lucky, no monsters suddenly appeared, Li Feng walked to the side of the dirt cave and began to pick these purple grasses.

System Prompt: If you have successfully used the top-level picking technique, you have obtained [Poisonous Comfrey] ×2.

Li Feng collected all these poisonous comfrey in one go, and there were fifty copies in total, which was very small.

These strange grasses are indeed highly poisonous, and they are a special medicinal material condensed by purple poisonous mist, which can be used to refine special poisons, as for whether they can remove the poison of purple poisonous mist, further exploration is needed. (To be continued......)
