Immortal Space

At this time, the siege of monsters had been going on for several hours.

The opponent's Tier 3 monster and his own Golden Core cultivator have been fighting since the very beginning, but now there is no trace of it, and it is unknown where the fight has gone.

The monster attacking the city was no longer as fierce as it was at the beginning, and the monks defending the city were also extremely tired.

The battle that lasted for several hours has already exhausted most of the monks' spiritual power (mana).

And the remaining four flying boats are still trying their best to kill the monsters in the rear.

At this moment, the foundation-building cultivators on the flying boat each hold a middle-grade spirit stone, and while manipulating the spirit weapon to kill monsters, they are trying to draw spiritual power from it to supplement their own consumption.

These middle-grade spirit stones were distributed to them in advance by the high-level officials of Boundary City, and they were specially used to supplement the consumed mana.

Although the huge spiritual power in the middle-grade spirit stone is not comparable to the second-level spirit wine in replenishing mana, it is much faster than drinking the first-level spirit wine.

This is the benefit of occupying a medium-grade spirit stone vein.

However, there are not many middle-grade spirit stones in the vein, and the total amount of mining during this period is only a few hundred yuan.

These numbers can only give one piece to each of the Foundation Establishment cultivators on the six flying boats, because they fight the most frequently, and if there is no supplement, they will have lost their combat effectiveness long ago.

At this time, a group of Wang Hong and Wu Dayong had killed more than ten groups of flying monsters in the city.

Wang Hong has already drank spirit wine and replenished his spirit power several times. Wu Dayong has been the shopkeeper for so many years, so he has naturally saved a lot of good products, and he even has second-grade spirit wine.

As for the eight qi cultivators, Wang Hong simply sold them a bottle of first-order spiritual wine at a low price, so as not to delay them too much.

It's not that he can't afford to give away the spirit stones of the first-order spirit wine, but that the two parties can't just give them away if they are not relatives or reasons.

The overall strength of the flying monsters entering the city was stronger than the human monks in the city at first.

However, after more than ten groups were beheaded by them, the overall strength of the two sides can now be equalized.

At this time, outside the city, four flying boats finally entered the beast tide from the left and right sides, pierced through from the middle, and temporarily divided the beast tide into front and back.

Seeing this opportunity, the two flying boats assisting the city defense also boldly rushed in from the front, and immediately caused chaos in a small section of the herd in front.

The six flying boats took the opportunity to move back and forth in the beast tide, sparing no effort to kill the monsters.

At this point, the vanguard of the beast horde was in chaos, and there was no energy left to attack the city. The monks defending the city wall finally won a respite.

As soon as the six flying boats killed the monsters vigorously, two third-tier monsters flew out from the beast tide again and charged towards the flying boat.

And the six flying boats were not afraid, but in groups of two, facing a Golden Core cultivator.

Gathering the power of hundreds of foundation-building monks, plus the protective shield on the flying boat, they fought a third-order monster together. In a short period of time, the two sides fought evenly.

The remaining two flying boats were in front of the city wall, still wantonly beheading the monsters so that they could not gather their strength to attack the city.

The two third-tier monsters realized that they couldn't take advantage of it today, and they gave off a strong coercion. At the same time, they roared at the beast tide.

Hearing the roar, the herd of beasts retreated in the direction they came from, led by the second-order monsters.

When the herd was far away, the two third-order monsters also turned around to catch up with the beast tide and retreated.

Watching the tide of beasts recede, the monks on the city wall collapsed to the ground one by one, feeling that they had lost the strength to move a finger.

The six flying boats returned to the city again, and it took another hour for the Jindan elders to return to Boundary City.

Although the monster group has retreated temporarily, there are still many things to do in the future.

The first one is naturally to clean up the battlefield and collect spoils.

The battle was too chaotic, and there was no time to clean up the corpses of the monsters. Now they can only be collected and distributed.

All these tasks should be done by Qi training monks, and some foundation building monks will be assigned to supervise them, and then handed over to Elder Jindan.

Wang Hong also allocated three demon pills and some miscellaneous monster materials.

In addition, the city must concentrate its efforts on mining spirit stone mines.

In today's battle, the mid-grade spirit stones played a huge role, otherwise the foundation-builder cultivators on the six flying boats wouldn't be able to last long.

The city vigorously summoned the monks to mine the spirit stone mine overnight, and even called some foundation building monks to mine the spirit stone.

At present, the monsters have only retreated temporarily, and now they are all staying a hundred miles away from the boundary city, ready to launch the second siege at any time.

Wu Dayong also came to Wang Hong and invited Wang Hong to mine the Lingshi Mine together.

"Foundation cultivators are not allowed to bring storage equipment, but can bring other magic tools into the mine, and use magic tools to mine spirit stones in the mine. Think about it, how efficient will this mining method be?"

"It's really fast, but how much can the mined spirit stone give us?"

Wang Hong was also a little moved. You must know that even if a foundation-building cultivator uses magic weapons like flying swords to dig a cave, it won't take too much time.

"Now is a special period, and the treatment will naturally be much higher. The spirit stones dug out are drawn one out of ten. If ten pieces are dug out, the mining monks can allocate one piece."

"Oh, is it really that high? Is it the same for middle-grade spirit stones?"

A foundation-building cultivator can at least dig out dozens of spirit stones with a single strike. One out of ten is already very high, and it will definitely make a lot of money in a day.

"Of course it includes middle-grade spirit stones, otherwise I wouldn't have invited you. If you're lucky enough to dig out ten middle-grade spirit stones, you'll be able to share one middle-grade spirit stone."

Wu Dayong also knew that Wang Hong, as an alchemist, was very wealthy, if it was just a low-grade spirit stone, he might not be able to appreciate it.

"It is indeed a very good opportunity to earn spirit stones to be allocated middle-grade spirit stones. Unfortunately, after a big battle, I feel that my body is not right. I need to recuperate, so I can only miss this good opportunity." Wang Hong said with a regretful expression. Said.

"That's such a pity. Junior Brother Wang's health is still important. You must take care of yourself. Keep the green hills. Don't be afraid that there will be no firewood. I will leave."

Seeing that Wang Hong couldn't go, Wu Dayong could only leave with regret for Wang Hong.

That night, the spirit stone mine was full of heat, and monks cheered from time to time.

Legends such as who dug up a middle-grade spirit stone always aroused bursts of envious exclamation.

Boundary City has no formation protection at this time, and there are only more than 10,000 monks in total. Today's battle has caused many casualties.

At this moment, most of the remaining monks went to the mine to mine spirit stones, and the number of monks patrolling the city wall was extremely rare.

And at this moment, a black shadow quietly sneaked out of the boundary city from the city wall.

After leaving the city wall, the black shadow did not go away, but walked towards a pile of monster corpses.

In this battle, the total number of beast hordes was much larger than the last time they besieged Jin'an City.

When the beast tide was launched last time, because it was a sneak attack, the number that could be launched was limited, and there were still some monsters guarding the mine veins.

This time, most of the monsters in the Boundary Mountain Range were concentrated. Although the time was not long, the number of deaths in the battle far exceeded the amount of more than two days last time.

Not counting the birds killed in battle inside the city, at least one hundred thousand monsters died in battle outside the city. After the useful parts of the monsters killed in battle were cut off, several mountains were piled up outside the city.

After the black figure approached the mountain of corpses, the monster corpses on the mountain of corpses disappeared one by one. After a while, the entire mountain of corpses disappeared without a trace.

The black shadow walked towards another mountain of corpses...

Early the next morning, the monks guarding the city discovered a strange phenomenon. Several mountains of monster corpses outside the city disappeared strangely.
