Hearing the voice of the fallen angel, everyone couldn't help but look in the direction of his finger.

Looking from afar, I saw a large pile of wooden barrels neatly stacked next to an inconspicuous big tent in the barbarian barracks. The barrels are very similar in size and shape to the barrels used by the defenders of the Great Wall to hold crude oil.

Don't...... Is it crude oil?

Yue Tian's heartbeat suddenly accelerated.

At this moment, I saw two barbarian soldiers walking up to the pile of barrels, and each of them picked up a wooden barrel, and then walked towards a bonfire not far away.

The campfires in the barbarian barracks are not the same as normal campfires. They first dug a circular pit in the ground, and then built a 20-centimeter-high edge around the pit. Each campfire pit has a shelf that can be used to hang pots to boil water and grill food.

When the two barbarian creeps with wooden barrels walked to the campfire pit, one of the minions pulled the stopper from his hand and poured the liquid from the barrel into the campfire pit.

Due to the distance, Yue Tian and the others couldn't see clearly what the liquid flowing out of the wooden barrel was. However, after the barbarian soldier poured the liquid in the barrel into the bonfire pit, he only heard a "whew", and the flames that were about to be extinguished in the bonfire pit suddenly rose nearly two meters high.

As soon as everyone saw this formation, they immediately guessed what the liquid in the barrel was. Everyone exclaimed almost in unison:

"Crude oil!"

"No, that's not crude oil." Yue Tian touched his chin and squinted thoughtfully.

"What? Not crude oil? Boss, you're not dazzled, are you? You see that the flames are so high all at once, what is not crude oil in the barrel? The fallen angel immediately answered.

"If I'm not mistaken. That's a refined essential oil! Yue Tianmeng's eyes widened, and two rays of light suddenly shot out of his eyes.

"Essential oils?" The crowd didn't quite understand.

"Essential oil is a high-quality petroleum that is extracted from crude oil. Although this essential oil is not as good as gasoline or diesel in our reality, it is compared to crude oil. This essential oil has fewer impurities and burns much better than crude oil. Before Yue Tian could speak, the Hujing Daoist beside him rushed to open a "literacy class" for everyone. This kid is an alchemist profession, and the process of refining essential oils from crude oil is originally one of the skills of alchemists.

"In this way, this essential oil is more high-end than our crude oil. If we have enough essential oils, what if the barbarians come to attack the city? It's a big deal to have a few more barbecue meetings. The hunter said in gray tones. The gray wolf beside him, who was inseparable from him, also whimpered and echoed his master.

"It's a pity we don't!" Holding a large bone in his hand, he shrugged his shoulders as he teased the gray-toned pet wolf Warrior Flame, Incineration. After saying that, he threw the big bone into the air, wanting the gray wolf pet with gray tones to come to the air to catch something.

Who knew that the gray wolf crawling on the ground didn't even lift his eyelids in the face of his usual favorite big bones. It rolled its eyes at the ghost flame and the incineration in disdain. Then she threw the back of her head at him. This fierce wolf warrior deserves to be the most beloved pet in gray tones. Anything else that is fed to it except the gray tones, it doesn't give a damn.

"Wow! I didn't expect this beast to have a lot of backbone. Come on, I won't tease you this time, let's eat! "Ghost Flame and Burning Death were so happy when they saw that the spectrum of a pet wolf warrior was so big. The kid bent down to pick up the big bone, and brought it to the gray wolf's mouth again.

"Woo......" Seeing that the annoying human being of Ghost Flame and Burning Death came towards him again, the gray war wolf immediately turned his head and glared at Ghost Flame and Burning Death, and let out a low roar of warning in his throat.

The kid Ghost Flame and Incineration immediately retracted his hand in fright. With a sneering look on his face, he said angrily:

"I don't want any good things delivered to my door, what a brute who doesn't know what to do!"

Hearing the words that Ghost Yan and Burning Death said casually, Yue Tian, who had been bowing his head and groaning, suddenly frowned.

"Of course you have to ask for something good to deliver to your door! Ghost Yan, you're on the point this time! Yue Tian smiled and patted the shoulder of the ghost flame and the burning corpse.

"Idea? What's the idea? The ghost flame and burning that Yue Tian was confused by and said blankly.

Yue Tian did not answer the ghost flame and burning. He excitedly clicked on the guild channel, and then sent out a guild message.

"Please come to the first beacon immediately for thieves above level 25, there is an important mission!"

A few minutes later. The thief players above level 25 in the Nirvana Guild Online all came to the first beacon where Yue Tian was.

Yue Tian counted the group of Nirvana Thief players in front of him, and there were actually nearly two hundred people!

And it's no wonder. As the current number one person in the world of reincarnation, Yue Tian, the only thief hidden winner. He has always been the banner figure of the Nirvana Guild, and a large part of the players who joined the Nirvana Guild came for his name, and many of them were thieves like Yue Tian.

It can be said that at present, more than 70% of the thief players with the highest level and the best awareness and operation in the Qin Ding Empire are members of the Nirvana Guild, and there are many of them like Xiaoxiao Stupid Cat, Moonlit Night Star, Midnight Sadness, Shu Lian and Shadow Sniper, these top and different styles of thief master players.

As long as Yue Tian is willing, the Nirvana Guild can completely form a "Crazy Thief Group" with extremely strong combat effectiveness, in fact, Yue Tian has already had this idea, but he has not been free to do this.

Now there is a chance to test the strength of the Nirvana thieves. If Yue Tian's plan can be successfully completed this time, then the formation of the "Nirvana Bandit Group" will be a sure thing!

After gathering the group of nirvana thieves in front of him, Yue Tian cleared his throat and said to everyone:

"Nirvana's Thieves Brothers, I'm calling you together now because I need to pick a team of elite Rogue players to complete a very dangerous mission. Due to the difficulty of this task, I can't guarantee that you will all come back alive. So I need everyone to sign up voluntarily and then make a selection. Okay, no more nonsense, brother thieves who are willing to follow me to complete the task, take a step forward! ”

Yue Tian's voice did not fall, only listened to "Bang!" With a bang, the more than two hundred Nirvana thief players in front of them took a big step forward as if someone was shouting a password.

Yue Tian didn't expect the thieves players of Nirvana to be so united, he looked around at these thieves players with emotion, and saw that each thief player's eyes were emitting a blazing light.

Being able to fight side by side with his boss, Xin Yi, a thief in the reincarnation world, is something that Nirvana Thief players are proud of! Now that the good opportunity has come, who will take half a step back?

"Good, good!" Yue Tian looked at Nirvana's thief players with some excitement and nodded approvingly, "There really aren't any bad seeds in our Nirvana Guild!" Everybody's doing well! However, this mission is more special, I can only lead thirty thieves to carry out the mission, but don't be discouraged, next our Nirvana Guild will fight for seven days on this desperate Great Wall, everyone has the opportunity to make contributions! Okay, now I'll start picking people! ”

Ten minutes later, Yue Tian carefully selected thirty thief players from among the more than two hundred Nirvana Thief players. The average level of these rogue players is above level 28, and they are the best choice in terms of awareness, operation, combat effectiveness and teamwork, and they can be said to be the elite thieves of Nirvana.

After Yue Tian comforted the unsuccessful thief players, he arranged for everyone to return to their respective posts. As for the thirty elite thieves who were selected, they were led down by Yue Tian to the Great Wall of Desperation.

Next to the Qin Ding military camp on the south side of the Great Wall of Desperation, thirty Nirvana Rogue players with joy and pride on their faces lined up in three rows in front of Yue Tian.

Yue Tian took a step closer to these thief players and said:

"Brothers, we are going on a very dangerous mission later, and now I order: everyone except for the necessary life recovery potions, empty all the contents of your backpack!" After speaking, Yue Tian was the first to start vacating his backpack.

Although Yue Tian's order was a little inexplicable, none of these thieves asked what they were doing, and everyone began to vacate their backpacks.

A minute later, each Rogue player was piled up with a pile of miscellaneous stuff in front of them.

Seeing that everyone's backpacks were empty, Yue Tianchao said to the dust beside him:

"Store everyone's things in our temporary warehouse, and be careful not to mess up."

"Don't worry, I promise that when you come back, you won't be short of even a big man." The dust laughed exaggeratedly and everyone said.

Hearing the words of the dust, all the Nirvana thieves laughed. The tension before the departure suddenly eased a lot.

At this time, Yue Tian looked around, and then said to the Nirvana thieves with a mysterious expression:

"Attention, everyone, now I will tell you about the content of our mission."

Seeing that the boss Yue Tian was finally about to announce the content of the mission, all the Nirvana thieves suddenly pricked up their ears one by one.

"Brothers, as you may know, we have run out of crude oil to defend the Great Wall. Crude oil is a powerful weapon for defending cities, but as far as I know, there is one thing that works better than crude oil, and that is the essential oil extracted from crude oil! And our task for a while is to get essential oils! ”

"Getting essential oils? Boss, where are you going to get this thing? One of the Rogue players in the team raised his hand and asked.

"Where to get it? Hehe...... "Looking at this thief player who asked the question, Yue Tian didn't answer immediately. I saw him grinning, raised his hand and pointed to the outside of the Great Wall of Desperation behind him, and said to the Nirvana thieves word by word:

"Barbarian-Clan-Army-Battalion!" (To be continued......)
