Just when Treasure Bay was in a carnival, Leng Feng, as the protagonist, did not participate, because, at this time, he was arranging for people to carry some ore mining equipment into the Proudmore auction house.

These devices cost Leng Feng nearly thousands of gold coins.

When the three-day carnival time in Treasure Bay passed, all over the bay were plastered with notices of missing people, and the content of the notices was to find the five-person team where Khadgar was, and it was the Prodmore Auction House.

A few days passed, and to Leng Feng's surprise, the brown-haired man Adolf took Khadgar and a group of five people to the Proudmore auction house.

When Leng Feng explained the upcoming action, the brown-haired man Adolf patted his chest and promised to complete the task, because, in their hearts, they still owed Leng Feng a great favor, that is, the five bottles of primary super grade potion.

Early in the morning of the second day after the arrival of the five Khadgars, in front of the Proudmore auction house, Leng Feng sorted out the team that was about to leave. Senjin and thirty well-armoured, metal-armed Darkspear Trolls stood beside Leng Feng, and judging from the aura of these Darkspear Trolls, it seemed that the equipment Leng Feng had provided them with was very satisfied.

At the front of the line were the five of Adolf and Khadgar, and behind them, stood hundreds of goblins carrying parts of mining equipment.

These goblins, all from the goblin poors of the Savage Coast, since the last battle with the cannibal trolls, these goblin poors have suffered a lot of vitality, this time Leng Feng intends to requisition some manpower, so he did not hesitate to choose the goblins there, which can be regarded as a gift to the place where he once stayed.

This special team left from the Treasure Bay in such a mighty way, and there were many people in the Treasure Bay who were still very strange, and they didn't know what Leng Feng was going to do with so many people.

Only Leng Feng himself knew that in the depths of the mountain behind the jungle, there was a vein where many Arcane Crystals were buried.

In the days leading up to the engineering battle, Leng Feng had been wandering around that vein, not because of anything else, but because the long vein of the Acanon Crystal was accompanied by a powder called Inert Dust, which was the key to making the Ancient Goblin Engineering Bomb.

Arcanon crystals generally absorb a large number of elements, and elements are more unstable in the world than gunpowder. Inert dust is the substance that minimizes the activity of the elements, and without inert dust, it is undoubtedly impossible to form a vein of arcane crystal.

Ever since he saw the Arcane Crystal necklace around Senkin's mother's neck, Leng Feng knew that the Ancient Goblin Project Bomb could be crafted, because there were ore veins, which often represented inert dust.

The value of the Aoneng Crystal, from the fact that the old man Lack has collected more than a dozen of them for several years, can be seen that each Aoneng Crystal is extremely precious, representing a large number of gold coins, which can be described as the hard currency of this world.

However, Leng Feng thought of more than just making money to develop the Aoneng Crystal vein, most of the reason was because engineering needed a lot of Aoneng Crystals, especially the Reaper T200, and the Aoneng Crystals needed were not ordinary Aoneng crystals, but a kind of Acaneng crystals that reached the best quality.

In addition, Leng Feng's newly obtained design drawings, the black technology * arcane rifle, and the arcane crystal is charged with an arcane crystal.

In its simplest version, the rifle can unleash an arcane attack equivalent to the power of the three-ring arcane force, and it is fired in bursts.

If the energy produces this kind of rifle, the army equipped with the Arcane rifle is undoubtedly a great weapon on the battlefield.

Thinking of this, Leng Feng's heart was on fire, and it was precisely because of the Arcane Rifle that Leng Feng believed that why the once powerful black technology would be attacked by a group, because they were too powerful. After all, the ability of a civilian who is powerless to unleash the Triple Ring Arcane is undoubtedly a nightmare for the opponent he kills. What's more, the Arcane Rifle is just the tip of the iceberg of black technology.

When re-entering the Misty Valley jungle, Leng Feng's team was extremely cautious, with thirty Darkspear Trolls armed to the teeth scattered in all directions of the team, keeping guard, while Senjin was responsible for leading the way in front.

To be honest, in the jungle, only the Dark Spear Trolls who were born here and grew here would not get lost, and even if Senjin took Leng Feng to the location of the ore vein once, Leng Feng would not be able to go there alone.

Because the war between Booty Bay and those cannibal trolls has just passed, there are very few cannibal trolls in the jungle of Mist Valley, and there are so many people on guard along the way, so there are no accidents.

Out of the Valley of the Mist, there are two paths, one is the territory of the Gulabash Troll Empire, and the other is into the valley of the vast mountains.

There is no doubt that Leng Feng and his party will naturally not go to the territory of the Gulabash trolls to make themselves bored, although it will save a lot of time to get from the territory of the Gulabash trolls to that ore vein.

A few days passed in a flash, and after Leng Feng and his party had climbed several mountains, they came to the bottom of the valley of a mountain range, and outside this unknown mountain range was the territory of the Gulabash Empire.

And the location of the Ao Neng Crystal vein is under this mountain range.

Because of this, Leng Feng asked everyone to try not to disturb the birds and beasts in the valley, so as not to be discovered by those man-eating trolls.

The place where Leng Feng found the inert dust was a natural cave, this natural cave was covered in vines, and it was impossible to find the location of the cave without careful searching.

The reason why Senkin's mother knew about this place was because Senkin's father discovered the location of this place when he inquired about the Gulabash Troll Empire, and Senkin's father also brought an Arcanon Crystal to Senkin's mother as a gift. Later, Senkin's father died in battle, and Senkin's mother managed the affairs of the Darkspear tribe on his father's behalf, during which he brought Senjin here in order to mine some Arcanon crystals and exchange some materials with the treasure bay, which is why Senjin also knew where this vein was.

Leng Feng slowly entered the cave, before that, he asked the thirty dark spear trolls to be in charge of guarding within ten miles of the cave, and he himself led the five people of Khadgar's team into the cave, and hundreds of mining goblins followed not far behind them.

The purpose of this trip, Leng Feng had already made it clear to Adolf, and Leng Feng intended to let them lead these trolls to garrison here, as for the benefits, they were divided with them, which made the five Adolf a little overjoyed, and even Khadgar, who had never shown his emotions, was also very moved.

At this time, it was pitch black in the cave, and at this time, everyone took out a stone that emitted a white light to illuminate the cave.

This stone is called Moonstone, which is specially used for mining lighting, and this time because it is going to be mined, the cold front has brought a lot, so everyone has one piece.

The direction of the cave is oblique downward, although there are some forks, but the cold front that has come once, here will naturally not get lost again.

At the end of the cave, there is a concave mine, the mine is not deep, only a few meters, and it is here that the cold front excavates the inert dust.

Seeing this, Leng Feng commanded those mining goblins and began to assemble the mining equipment, and an hour later, a roar sounded in the cave, and waste soil and crystals were constantly being sent out, and those inert dusts were specially sorted by Leng Feng sent a few goblins.

The work of mining was carried out in such an orderly manner.

What Leng Feng didn't expect was that Khadgar had just come here, and he immediately sat down and started meditating.

Seeing this, Leng Feng was stunned at first, and then he was overjoyed.

Because, I was carried away by the excitement of developing crystal ore veins, and I didn't even realize at this time that this place was full of fire elements!
