Quartz ore is not uncommon in the Northland, and the composition of quartz ore and sand is very close, even if there is no quartz ore, sand can be used instead.

As for mushrooms, just collect some from around the ruins, the cultivation of mushrooms is not difficult, and the requirements for the environment are not high, Su Lun collected all the kinds of mushrooms here in the ruins, and then led people to catch all the remaining crystal beasts in the ruins.

The number of crystal beasts was not large, and there were twenty-six left except for the dead, and all of them were packed in cages and transported back. After finally searching the secret realm and leaving nothing of value behind, Su Lun walked back with the convoy.

Leaving the square, the monsters in the ruins all ran out of their nests, and the death pincer insects, giant centipedes, and a giant beetle like a tank rushed up immediately after discovering Su Lun and the others.

"Summon magical creatures!"

A six-pointed star array rose from the ground, and in the next second, four vigorous figures rushed out of the magic array, it was four silver giant wolves, these giant wolves were one meter and five meters tall at the shoulders, their bodies were strong, and their claws were sharp, and they rushed towards several mutant insects as soon as they appeared.

These giant wolves cooperated with each other, two harassments, two main attacks, if it weren't for the strong shells of those mutant beetles, they would have suffered heavy casualties.

"Lower your defense!"

"The whole army is excited!"

"Advanced Crowd Acceleration!"

"Crowd Demon Weapon!"

Spiritual light flashed from Su Lun's body, and everyone immediately felt that their bodies were full of strength. The centaurs continued to shoot arrows at the bugs, and clusters of steel arrows shot out mightily and then stabbed into the crevices of the mutant bugs' carapaces, green blood gushing out.

The gray dwarves had experience in dealing with giant beetles, and they attacked the limbs of the insects in small groups, and the sharp axes continued to slash at the joints of the insects' legs.

Those giant beetles didn't have time to resist, they cut off a few legs, and their huge bodies fell directly to the ground, and then they were swarmed by many gray dwarves and completely wiped out.

Several barbarian berserkers roared angrily, and then rushed forward with one hand wielding a giant axe, these big men who were more than two meters tall and full of muscles rushed to the back of the death pincer worm with a single jump? The powerful impact force directly caused the death pincer to smash to the ground? The giant axe in his hand slashed at its head even harder.

Protected by a hard carapace, but under the strange power of the barbarians? How many axes go down and the carapace is cut to pieces? Blood flies. The death beetle in pain swung frantically to shake the person off its back, but those savages stood on it with ease? Can't shake it off, but a few breaths? The movement of the death pincer insect is getting smaller and smaller? Finally collapsed with a bang.

"Fireball!"

"Chain lightning!"

"Ice Storm!"

Hathaway pointed at the staff in her hand, and a large fireball landed in the middle of the giant centipede, and a huge explosion sounded, and the giant centipedes around it were blown to pieces. A bolt of lightning flashed back and forth on the battlefield? Several giant centipedes were numb all over their bodies.

Countless ice blades appear out of thin air? Then it spun rapidly, and where the ice blade whirlwind passed, a large number of monsters were directly cut into pieces, and a large amount of blood smelled in the air.

With the clearing of everyone, the various mutated monsters in the ruins have rapidly decreased? With the spell blessings of Suren and Hathaway, the whole battle becomes very simple? In the past, it was still a headache to deal with such a rough-skinned monster, but after blessing various spells? Their weapons can easily tear through each other's defenses.

With Suren and Hathaway, the whole battle became very easy? Although there are a lot of mutant monsters rushing up? But it didn't make any waves. Soon with the cooperation of everyone? These monsters are either killed or run away.

After a simple collection of loot, the main thing is the carapace of insects, whether it is a giant beetle or a giant centipede, death pincer insects, these monsters have a large number of carapaces, these carapaces are hard, the toughness is also good, many carapaces are a good tower shield as long as they are simply trimmed.

After packing up the booty, the group returned to the goblin tribe again, and after converging the remaining troops, they escorted all the goblins back together.

The speed of the team's march became much slower, and the surrounding monsters had long since avoided the large army when they saw the large army, and along the way, Suren and the others did not encounter any enemies. The trip took three days to explore the ruins, and it was a great success.

After returning to the Minotaur's camp, Suren handed over the newly captured goblin slaves to the Drow Elves for training, and with the kobolds, the Minotaur camp soon had a workforce of nearly 5,000 men.

Suren named the city Crete City, and then commanded a large number of slaves to build the city, including the Minotaur, a large number of slaves began to build the city, and the most important thing in the underground world is the rock, more than two hundred Minotaurs mined the rock under the command of Chrissy, and then began to build the city after being repaired by the gray dwarves.

The city of Crete is small in size and has a small permanent population, and more often acts as a transit point to transport the minerals mined from the surrounding mining areas. Suren deliberately built a teleportation array in Crete City, and then appointed Chrissy as the lord of Crete City.

Su Lun now has a serious shortage of management talents, and there is no choice but to let Chrissy stay in Crete City temporarily, but because of the existence of the teleportation array, Chrissy can return to Zhenbei City at any time, and even manage the city in Crete City during the day, and will be attacked in Zhenbei City at night, without delay at all.

After having the support of the obsidian mines in Crete City, the wizard tower in Zhenbei City began to continue to be built, Suren did not stay in Zhenbei City for long, and he had to build a suitable breeding base for those crystal beasts as soon as possible.

Before the construction of the breeding base was completed, a piece of land was set aside in the north city of Sulun Town for these crystal beasts to live temporarily, and when they arrived in the new environment, these crystal beasts quickly adapted, probably because there was no radiation, these crystal beasts looked a little sluggish.

It is used to feed the crystal beast is the river sand and mushrooms and other plants collected by the Su Lun faction, and the meat is basically fish, and the supply of beef and mutton in the north of the town is still scarce, so it is naturally impossible to feed the crystal beast, but fish is also a good choice.

Su Lun is going to build the breeding base of the Crystal Beast in the secret realm, where the elemental energy is abundant, and the place is also hidden enough, as long as the equipment is reassembled, this place will be very suitable for the Crystal Beast to breed.

Coming to the secret realm through the teleportation array, after the repairs of the harpy, this secret realm finally looks a little popular, not as dilapidated and desolate as before.

"Welcome back, master!" the voice of Taling One rang in his ears.

"Long time no see, Taling One. Su Lun said hello casually.

"Master, this is the progress of the restoration of the secret realm during this time, as well as the list of materials needed to repair the secret realm. "Taling One projected a curtain of light, which recorded all kinds of materials, and just looking at a part of it made Su Lun's scalp tingle.

Although most of them were ordinary materials, the price required still made Su Lun feel painful.

"Alright Taling One, you should know the value of these materials, now we don't have that much money to buy them, so we can only repair a part. Su Lun rubbed his eyebrows and said.

"By the way, I got some Iron Golems this time, do you have any way to control them?"

"Master, I can try to control the Iron Golem, it will take time to break through their soul barriers. Taling One said.

"That's good, these steel golems are useless anyway, you just take your time to break them. Su Lun nodded, and then directly took a few steel golems out of the storage space.

Three of the six steel golems were damaged, and three were intact. However, these three intact ones were controlled by Su Lun using special methods, and they were unable to resist at all.

"Connecting the Steel Golems..."As soon as several Steel Golems appeared, Taling One instantly began to work, and a wave of soul fluctuations appeared. The steel golems instantly fell into a state of stupor, and the red light in their eyes began to flicker continuously.

"The connection was successful... Cracking is underway..."

"Target defense mechanisms are being analyzed..."

"The defense mechanism simulation is successful, and the invasion begins..."

"The intrusion was successful, and the original program of the target was revised... The program is being retargeted..."

With the icy mechanical sound of Taling One, a large amount of energy poured out of the elemental pool for Taling One to consume, and those steel golems seemed to suddenly fail, and their bodies continued to rotate.

"The modification is complete, and the Iron Golem has been successfully dominated!"

"The permission modification has been completed, and the current maximum permission is set to Suren. ”

"The setting is successful, the device is restarting..."

As a legendary-level tower spirit, Taling No. 1 has a crushing advantage over low-level Taling and Steel Golems, and these Steel Golems were successfully modified by Taling No. 1. Starting today, there are a few more Steel Golems in the secret realm.

The remaining three Steel Golems have been damaged, but Suren did not destroy them when he destroyed them, their damage was not serious, and after being scanned by Taling, they were fully capable of repairing them, and only needed to replace or repair the parts and cores of the Steel Golem.

There are many steel golems in the secret realm that have lost their repair value, and there are many intact parts left in these golems, which can be used to replace them directly.
