Because of his talent, Xu Feng can have two flying swords, one has been used as a combat weapon and has been used, and the other is in strict accordance with the records of the sword forging technique of the Sword Sect, using an ordinary-level long sword, which is conceived day and night with the essence of the true yuan, so that it has spirituality, condensed into a sword pill, and is hidden in the dantian;

This step took Xu Feng nearly half a year, no matter day or night, Xu Feng always carried this long sword on his back, and finally condensed the essence into an egg-sized sword pill, which was hidden in the abdominal dantian;

After the formation of the sword pill, it is a long stage of continuous pregnancy, this stage according to the records in the sword forging technique, the shortest time is six years, the longest is even more than eighteen years;

Xu Feng once remembered that in the sword forging technique, there were many predecessors' experiences, one of whom wrote, "Thirteen years of pregnant sword, one day to wipe out the enemies of the world, not too fast"

It took thirteen years just to conceive the sword, and you can imagine how difficult it is to have a flying sword of your own;

If it weren't for the good luck at the beginning and obtained a piece of the Five Elements Concentrate of the Innate Sword Blank, I'm afraid that by now, Xu Feng would not have a suitable flying sword as a weapon;

Looking at the seven-star dark gold quality long sword that firmly "bitten to death" his right hand and an arm, Xu Feng secretly sighed and put it into the storage ring;

Glancing at the hundreds of insect soldiers around him, Xu Feng took them all back, without the help of these insect soldiers, it would probably be a difficult thing to kill the skull crusher alone, but the soul energy consumed by Xu Feng in this battle was too large, and killing the mechanical clan could not get any soul energy supplement, which made people slightly depressed;

Looking at the bloodthirsty guardians around him and the mechanical exploration buildings more than ten meters high, Xu Feng was about to leave this area, without the D-level elite mechanical units, it was useless to stay here;

Just as Xu Feng was about to leave, he suddenly saw a flame burning behind a tilted mechanical exploration building;

Walking in, behind this mechanical exploration building, there was a treasure chest the size of a basketball, the surface of which was burning with raging flames, and it looked like a soldering iron that had just been taken out of the furnace, flashing with a crimson light;

On the side of the treasure chest, there is a mark of a mechanical gear, which seems to be still turning slightly after staring at it for a long time, and the slight friction sound of "click" can still be heard in the ear;

"This is ......" Xu Feng carefully identified it, and it took a long time to recall: "This is a treasure chest of legendary quality?" ”

Items are divided into one-star, two-star, three-star to nine-star according to the grade, and are divided into ordinary, black iron, bronze, silver, gold, dark gold, and colorful sacred according to the grade;

But between the dark gold quality and the colorful sacred, there are actually two more grades, which are legendary and epic;

And these two grades will not be obtained in the Destiny Chest, or by killing monsters, but can only be opened in the corresponding treasure chest, or purchased in the auction house;

The number of these two types of treasures is so rare that ordinary people may not see one in their lifetime, so they are rarely passed on;

The red flame burning on the surface in front of Xu Feng was a treasure chest of legendary quality, and there must be an item of legendary quality inside;

The epic treasure chest, on the other hand, has purple flames burning on the surface;

Xu Feng first took out a bottle of high-grade flame resistance potion from the storage ring and poured it down, before he began to approach this treasure chest;

The closer he got to the treasure chest, the more he felt bursts of stinging pain on his bare skin, and a series of more than a dozen points of damage came out from the top of Xu Feng's head;

Xu Feng's own flame resistance is much higher than that of others, plus he has poured a bottle of high-grade fire resistance potion, but he will still lose blood when he gets close, if it is someone else, I am afraid that if he is lucky to meet a treasure chest of legendary quality, he will not be able to open it closely;

The flames on the surface of the epic treasure chest are even more powerful, and I am afraid that with Xu Feng's current strength, he will not be able to get close to opening it, unless it is a treasure that is immune to flames;

Enduring the burning pain, Xu Feng came to the insurance and began to slowly open the treasure chest;

Fortunately, most of the legendary quality and epic quality treasure chests in the wild are unlocked, which is a good thing for Xu Feng, who has not learned lock-picking skills;

Now Xu Feng recalls the first time he encountered a locked treasure chest, and then smashed the lock, and he still feels a little funny in his heart;

If the legendary quality treasure chest is locked, if it is smashed, there is no weapon as sharp as a flying sword in Xu Feng's hand, it is simply wishful thinking, coupled with the surface flames, I am afraid that they will not even be able to get close to the treasure chest within three meters;

Xu Feng pressed his hand on the treasure chest seal, and a progress bar appeared in front of his eyes;

System: Open the treasure chest, progress 1%...... 3%…… 9%……

The legendary quality treasure chest seemed to sense that Xu Feng was opening, the flames suddenly became vigorous, and they burned more than three feet high, the flames kept licking Xu Feng's arm, and the scorching sting pain came, Xu Feng seemed to be able to feel that his arm was like barbecue, and it was making a "zizi" sound;

The blood volume is constantly decreasing, and every time it beats, it is nearly a hundred points of damage, which is not good enough because Xu Feng has more than 8,000 points of blood, which should be able to support the opening of the treasure chest;

Looking at the slow progress of unpacking, Xu Feng frowned slightly;

"It seems that I should buy a lock-picking skill book, if I encounter such a treasure chest next time, if there is no unlocking skill assisted by the unlocking speed bonus, I'm afraid just opening the box is a very troublesome thing."

Lock-picking skills, not only can only open locked treasure chests, but also can speed up the opening of boxes, the higher the level of lock-picking skills, the faster the speed of opening boxes;

Practice your lockpicking skills to the highest level, and you can even speed up unpacking by up to 80%;

Moreover, the more advanced the treasure chest, the faster the proficiency of the lockpicking skill will improve, and it is obviously an invisible waste and loss to open such a legendary quality treasure chest without lockpicking skills;

When Xu Feng's blood volume was less than 1,000 points left, this legendary quality treasure chest finally made a crisp "click" sound;

The chest opened slightly, revealing a crimson glow inside;

Xu Feng quickly lifted the treasure chest, swept away the treasures inside, and then quickly moved away, not caring about what treasures he had taken, he directly took out a bottle of high-level healing potion and poured it into his mouth;

Then he took out a piece of barbecue meat from the storage ring and began to devour it slowly, this is also the food that can restore the blood volume, under the double addition of blood, the dazzling red light that Xu Feng's blood bar has been flashing has finally slowly disappeared, and the blood volume began to increase rapidly;

With his blood volume restored, Xu Feng began to check the newly acquired treasures in his virtual backpack, and a hint of surprise flashed in his eyes;
