The procession of nearly 300 people went down in a mighty way, some people were mining, some were carrying, some were building platforms, and everything was in order.

Xiling Chen commanded, adventurers with soil ability to carry out the initial excavation work, when they hit rocks, or minerals, they changed people, legends, supremes, and even the two emperors acted in person, no one was lazy, everyone was working seriously, and the excavation progress was very fast in such an environment.

A steady stream of gravel and gravel was transported to the surface, and in less than two hours the team dug more than 300 meters diagonally downward.

The undead don't need air, and the undead who have their own bodies don't need to breathe or anything like that, even if the underground environment is bad, it won't affect everyone.

More than 300 meters deep, there are already minerals appearing, it is an ordinary magic iron ore, it can go to the Qianshan pit to mine, this ordinary iron ore is not needed at all, at least it is a legendary-level mineral, and the excavated iron ore will be transported to the rear and directly smelted into a metal platform support or something that reinforces the pit.

Xiao Ling had already scanned the distribution of minerals, and he needed to continue digging down more than 500 meters, and more than 700 meters deep from the ground before he could touch the rare ore veins.

The undead plane has its own level, which just corresponds to the level of the adventurer.

There are a total of seven levels, the level of the Demon Venerable is the seventh level, the Great Emperor is the sixth level, the Supreme is the fifth level, the legend is the fourth level, and then the spirit level, the heaven level, the earth level, if calculated according to the game level, it is one to one hundred and sixty levels, the Great Emperor belongs to the one hundred and fifty level of the strong, the Supreme is one hundred and thirty levels, and the legend is one hundred levels.

Legend is also level four.

Minerals below the fourth level are not needed at all, these minerals can be mined outside, and Xiling Chen is very confident in himself, if he digs the top veins this time, maybe the fourth-level mines are not needed.

A few hours later, a high-grade ore vein was finally dug up, and this ore vein was also detected by Xiao Ling, which was more than 700 meters underground.

"My lord! It's a crystal sapphire mine! The member in charge of the excavation shouted excitedly.

Crystal Sapphire Mine, this is a gem type vein, and the role of Crystal Sapphire is very simple, increase mana storage and magic amplification, and it is all elemental, the amplification effect can reach 60%, as long as you find a gem carver with good skills, it can be set on weapons or equipment.

The grade of this vein is about level 4, and it can be mined with less level 5 gem ore.

The fourth level is also legendary, and the crystal sapphire can increase the magic ability of legendary equipment by 60%, which is a very huge improvement, and if it increases to the supreme level, it will weaken by half, about 30%.

Of course, the Kicker Supreme can use a level 5 crystal sapphire, so that there will be no weakening.

"Some people dig gem mines, others advance in the other direction, this direction, diagonally digging down!" Xi Lingchen commanded.

The members of the nearby Purple Phoenix Immortal Kingdom immediately took action after hearing this, some strengthened the cave, and some expanded the scope of the cave, intending to use this place as a transit station, after Xiling Chen designated the direction, the team began to work, and after expanding the pit, the Cold and Dark Empress took some members to start digging.

Xilingchen was not idle, using his spatial ability to transport the gravel to the rear.

Two hundred skeleton knights have built a transportation channel in the mine, which can quickly transport the gravel and excavated minerals to the surface, in fact, this kind of excavation is still very slow, after all, the preparation is insufficient, and the other forces come in with all kinds of advanced excavation tools, and the mining tunnels and the like are all advanced with large magic guide machinery, and even mechas, and the efficiency is not known how much faster.

It took more than three hours for the team to open a mine path underground, and this time the minerals encountered were not of high grade, but Xilingchen knew very well that there were better minerals ahead, so he did not let everyone stop digging, but continued to push down.

Since he wants to solve the problem of annihilation of the undead plane, Xiling Chen plans to let the Purple Phoenix Immortal Kingdom develop rapidly, and strive to dig up resources for several years this time, and it is best to fill all the warships.

In this pit, although I dare not say that there are seventh-level veins, there must be sixth-level ore.

Continue to dig more than 300 meters below, and sure enough, I came across a good ore vein, this time I encountered a fifth-level ore vein, a supreme-level ore vein, and a mixed ore vein, there are everything, there are energy crystals, gems, and metal ores, after finding this ore vein, Xilingchen let the large army dig in this area.

The Supreme class is enough, transport these minerals to the battleship, and when the time comes, make a batch of Supreme-level weapons and equipment for the dragoon squad to equip, so that an elite combat force can be formed.

The dragoon squad is the skeleton knight squad, the reason why it is called the dragoon is because the three bloodlines of the Kowloon goldfish are given to the three people of the dragoon squad, and when the skeleton knights have their own bodies, Xilingchen will let them turn into special classes such as dark knights and death knights.

The Nine Dragons Golden Fish can be divided into eight bloodlines, two of which belong to the two empresses, three to the dragoons, and the remaining three have not yet been chosen, Xi Lingchen plans to take a look.

And there is such a thing as bloodline, you must have a body, so you have to wait for the skeletons that come out of Bone City to condense their bodies before you can choose who to give it to, if you don't have a body, even if you want it, you can't do it.

Time passed day by day, and the members of the Purple Phoenix Immortal Kingdom were as isolated as they were from the world, mining every day, over and over again, although it seemed boring, but in fact, everyone's emotions did not decrease in the slightest, but they were all working hard, this is because there will be surprises every day.

Fourth-level ore veins, fifth-level ore veins, sixth-level ore veins, and even seventh-level ore veins, you can dig high-level resources every day, even if it is boring, it is very happy.

Everyone knows that the excavation now is for the rise in the future, and when the time comes, the equipment of the Purple Phoenix Immortal Kingdom will all start at the legendary level, according to the level of the equipment, the basic human hand spirit level or immortal weapon, magic weapon.

Mining can't go on like this, because the Ghost Valley is about to close.

Before the Ghost Valley closes, there will be a spirit signal similar to the general notification, this signal will last for three times, and it will be closed after the third end, under normal circumstances, ordinary adventurers will leave when the first signal is given, and the adventurer team with a force like the battleship will leave when the second signal is given.

After Xiling Chen carried out the initial command, he did not continue to be in the mine after that, he was using the excavated materials to make weapons and equipment, Xiling Chen personally made it, it must be at the silver level, and it is definitely equipment at the level of immortal weapons.
