It would be a pity to kill these gold-eating rats. Find the rat king and beat him up to force him to recognize his master.
It is most cost-effective to use the Rat King to command the entire rat group to help dig holes and speed up the advancement.
The Guichen Flame burned into the cave where the rats were. Wang Daoyuan was afraid of hurting the group of gold-eating rats, so he immediately put away the Guichen Flame.
The rats were very alert and were too frightened to move when they saw that the returning flames could burn through hard rocks.
After Wang Daoyuan returned to Chenyan, the rats watched him eagerly and wanted to surround him, but they were afraid that he would release the terrifying flames again.
After waiting for half an hour, a mouse over a foot long crawled over.
This mouse looks similar to other gold-eating rats, except that its large teeth are golden and its length is more than three times that of other gold-eating rats.
The spiritual power fluctuations on its body showed that it was a second-order low-grade monster, not far from the second-order mid-grade monster, and its cultivation was comparable to Wang Daoyuan.
It made a "squeaking" sound at the rats, and the rats began to commotion.
After a while, hundreds of first-level, top-grade gold-eating rats rushed towards Wang Daoyuan.
Wang Daoyuan wanted to lure out the Rat King, so he didn't subdue them directly, but used earth-attribute spiritual power to prop up a protective shield.
A group of gold-eating rats gnawed around the protective shield, but the earth-attribute spiritual power in the protective shield had the corrosive effect of the dust-returning flame. When the rats gnawed, the big teeth would also be corroded.
Wang Daoyuan can use his spiritual power to continuously replenish the protective shield. If his spiritual power is insufficient, he can also drink some red blood brew to restore his spiritual power.
A quarter of an hour passed, and the teeth of the gold-eating rat that pounced first were almost corroded and could no longer chew on the protective shield.
The Rat King was furious and jumped around on the spot.
More than a hundred gold-eating rats rushed forward and continued to chew on the protective shield.
There was no difference in the result. They only chewed for a quarter of an hour, and the large teeth were too short to bite.
The other gold-eating rats in the rat group did not dare to come forward. After the rat king squeaked a few times, he rushed forward himself.
Just waiting for it to come out, this guy has been hiding in the rat hole. Wang Daoyuan was afraid of using his true skills, so the rat king ran away directly along the rat hole.
By then, he would never have a chance to catch the Rat King again.
The speed at which the returning dust flame burns the stone wall is far slower than the speed at which the Rat King escapes along the rat hole.
If the Rat King comes out to seek death on his own, it will be easy to handle.
Wang Daoyuan summoned the Soul-Destroying Bell, but only exerted 10% of the Soul-Destroying Bell's power.
All the first-level gold-eating rats fainted.
The Rat King was also a little confused and could not stand firmly.
Wang Daoyuan used the quagmire technique to trap the Rat King.
The Rat King fell into the quagmire and could not move.
The mire was created by earth-attribute spiritual power and was corrosive. The Rat King had to activate his spiritual power to resist corrosion.
Wang Daoyuan sent a message to its spiritual consciousness: "Either surrender to me or die."
It is not difficult for the second-level monster to understand these words, but after all, the Rat King is the king of his clan and has his own pride and is unwilling to give in easily.
Wang Daoyuan summoned the Guichen Flame, forming a fire circle three feet in diameter with the Rat King as the center.
Then he slowly narrowed the scope of the fire circle, and when the flames burned past, a small pit an inch deep was burned into the ground.
Seeing that the fire was about to burn his tail, the Rat King let out a whine to express his surrender.
Wang Daoyuan did not put away the Returning Flame, nor did he remove the Quagmire Technique, but the fire circle stopped shrinking.
He sent a message to the Rat King: "Don't resist, I will let you go after I recognize my master.
If you dare to resist, I will burn you with fire."
The Rat King nodded obediently, indicating that he did not dare to resist.
Wang Daoyuan began to use the method of recognizing the master in the secret code of controlling spirits. After a quarter of an hour, the recognition of the master was completed.
As soon as he thought about it, the Rat King immediately rolled on the ground in pain.
Confirming that the master was indeed successful, Wang Daoyuan put away the Return to Dust Flame and removed the Quagmire Technique.
His life was saved, and the Rat King jumped up and down happily.
One day later, all the stunned gold-eating rats came to their senses.
Wang Daoyuan passed the Rat King and ordered the rats to drill holes in the rocks.
It is better to bloom more and dig several small holes in one place at the same time.
When the dust flame is released to burn, the flame pours into multiple small holes and burns at the same time, more than doubling the speed.
He originally wanted the gold-eating rat to dig holes in the front, while he set fire to the rocks in the back.
But these gold-eating rats are too timid. They run away when they see Gui Chenyan and don't dare to dig holes at all.
In desperation, he could only let the gold-eating rat dig a hole first. After digging forward for a mile, the gold-eating rat withdrew, and then he released Chen Yan.
The speed of burning rocks is much faster. It can advance one mile in two days, but it cannot be burned all the time.
At each mile advanced, stop burning and let the gold-eating rats dig holes.
It takes a gold-eating rat three days to dig a mile-long cave in hard rock.
Overall, the average progress is one mile every five days.
However, Wang Daoyuan has three days of practice every five days.
In order for the gold-eating rats to contribute, they must be given some benefits, otherwise they will be passive and slow down their work.
Fortunately, the gold-eating rat is not picky about food and will eat anything from watermelon rinds to bones to rotten wood.
He felt a little guilty after taking some leftover materials from space products and letting these gold-eating rats dig holes.
With enough practice time, Wang Daoyuan's cultivation has also improved.
One month after conquering the gold-devouring rats, his cultivation level finally broke through and reached the fourth level of foundation building.
There have also been changes in the space, and the concentration of spiritual energy has increased a lot, reaching the level of second-order high-grade spiritual veins.
However, the size of the space did not change. After the incense test, it was found that the time flow rate had not changed, and was still forty times.
Wang Daoyuan observed the boundary of the Lingzhu space through his clone and discovered something unusual.
When I first discovered the Lingzhu space, looking out from inside the space, there was a gray mist everywhere, with a hint of purple in the gray.
There is obviously less purple now, and the gray fog has become thinner.
Where the gray fog is extremely thin, you can still vaguely see a large area of dark space through the fog.
After observing carefully for a long time, the clone also discovered that there seemed to be a slight crack at the edge of the spirit bead space, and gray mist leaked from the crack.
It's just that the leakage speed is very slow, and the space is not affected.
It seems that this spirit bead has been seriously damaged. This promotion only increases the concentration of spiritual energy, but does not increase the size of the space and does not speed up the flow of time. This may be related to this damage.
If this damage cannot be repaired, I am afraid that the size of the spirit bead space and the flow rate of time will not change again in the future.
The current space size and time flow rate are sufficient. As long as the spiritual energy concentration increases, third-level spiritual plants can be planted.
In the future, as your cultivation level increases and you find high-level spiritual objects, you may be able to repair the cracks on the spiritual beads.
It's useless to think about it any more now. Let's just set fire to the stone, reach the location of Guishui Mingquan as soon as possible, and get the water attribute spiritual fire.
Improving one's own strength is the most important thing, as long as the Lingzhu space is enough.
After the cultivation of the fourth floor of the foundation was consolidated, the returning dust flames continued to be released to burn the rock wall.
The concentration of spiritual energy in the space increased, and the Returning Flame burned more vigorously.
The speed of burning rocks has also been slightly accelerated, but the advancement speed has not increased.
The closer to Guishui Mingquan, the more underground water veins there were. In order to save his life, Wang Daoyuan could only avoid these water veins.
It cannot advance in a straight line, so the distance required to dig is longer.
