In the next half a year, the energetic two took root in the fire frog swamp, during the day, the two went out to kill the fire frog, Tong Li, resisted the fire frog and constantly honed his ten thousand grinding strength, and Sun Hao used a large number of fire frog skin to practice making blank rune paper.

In half a year, although in terms of cultivation resources, the two of them did not gain much, and even consumed a lot of cultivation resources, but the cultivation effect was extremely good.

Tong Liwan has made rapid progress, and has advanced to the late stage of the third layer, Sun Hao's annual ring wood needs to accumulate a large amount, and in half a year, it has also reached the peak of the third layer of qi refining, and as long as there is an opportunity, it is possible to break through to the fourth layer of qi refining.

In half a year, in addition to the improvement of qi refining cultivation, the two of them also had one of the biggest gains, that is, the casting speed has been greatly improved.

Sun Hao's casting speed was shortened from two breaths to one breath, and the casting interval was shortened to half a breath, Sun Hao made such a huge progress, I don't know what Cheng Dù would surprise his master again. Tong Li's progress is still obvious, and the time for the Earth Qi Shield to be cast has been shortened to two breaths.

Sun Hao's talisman making technique has also made great progress, a fire frog skin can already refine three to five blank rune papers, although the blank rune paper is not very valuable, but no matter how small the mosquito legs are, they are still meat.

It can be regarded as a hard work that pays off, and in half a year, Sun Hao's speed of refining blank rune paper with fire frog skin has reached the level of other disciples refining blank rune paper with other materials. For this alone, Sun Hao can be proud**.

Tong Li thought that this was more than worth the loss.

Tong Li, like the other disciples, didn't think that practicing the blank rune paper would be of any help to his cultivation.

The difference between Sun Hao and Tong Li lies in the understanding of cultivation, in the cognition of the monk system, in Sun Hao's cognition, Fu Dao is also one of the avenues of monks, and the method of Fu Dao cultivation is broad and profound, and it is also one of the paths of single law to heaven. And the method of refining blank rune paper is the basic cultivation method of the rune path, and in Sun Hao's understanding it is the foundation, and Sun Hao, who has already tasted the sweetness of Wanlun wood, naturally attaches great importance to the foundation of his own cultivation.

Although it is not yet known what special help refining blank rune paper will have for the rune path, Sun Hao thinks that practicing this basic lesson well is only good for himself, and there is no harm in practicing hard.

With the killing of Sun Hao and Tong Li, the number of fire frogs decreased sharply, and the battle line of the two continued to advance from the edge of the fire frog swamp to the inside of the fire frog swamp.

Although the Fire Frog Swamp has accumulated a large number of fire frogs over time, it cannot withstand endless killing. Fortunately, in the past six months, as the number of fire frogs has gradually decreased, the quality of fire frogs has continued to improve. At first, the number of low-level fire frogs was the majority, but after going deep into twenty miles, the fire frog team was in the middle stage of qi refining.

In the middle stage of qi refining, the blood of the fire frog is more refined, and the quantity and quality are stronger, so although the number of fire frogs killed every day has decreased, the blood of the fire frog required for Sun Hao's Five Elements Wheel Spirit Recipe refining has increased instead of decreasing.

For the Five Elements Wheel Spirit Formula, Sun Hao couldn't help but be very depressed, because the foundation was too solid, and Wanlun Mu, especially Mu Dan, was too strong, after half a year, although the fire strength was a lot stronger, but in front of Mu Dan, he was still like a strong man like a child, not worth mentioning, and there was still a long way to go from the wheel fire spirit root.

Half a year has passed, the two have gone deep into the fire frog swamp for thirty miles, the range of hunting fire frogs is larger, the fire frog cultivation is improved, a single fire frog has a sense of territory, and the hunting methods of the two have also changed, due to the decrease in the density of fire frogs, and more fire frog cultivation has approached the late stage of qi refining, and the spiritual intelligence has also improved, the previous pit killing is no longer suitable, and the swamp terrain is not suitable for the wall.

So the two hunted the fire frog and became a single pick-and-kill, searching and meeting the fire frog, Sun Hao a convex wooden stake led over, Tong Li Tuqi shield on the top, and then, Sun Hao's convex wooden stake and Qingmu tangle attack to death, and dealing with low-level fire frogs two times is different, the current fire frog, Sun Hao needs to continue to use the help of green wood entanglement to make Tong Li stabilize the formation, the convex wood stake is close to the late stage of gas refining The lethality of the fire frog is also sharply reduced, often to eliminate a fire frog, the two need a quarter of an hour to half an hour or so.

Half a year later, the two of them killed more than 30 fire frogs again on this day, and then returned to the cave and began to cultivate.

This harvest is good, thirty fire frogs, not only contributed two bottles of hard work, but also the temperature of this hard work is higher, and the color is more bright.

As usual, Sun Hao swallowed his heart and began to refine.

After half a year, refining the heart and blood has almost become Sun Hao's instinct, skillfully and quickly decomposing the blood mass and refining.

Drop by drop of fire frog blood was quickly refined in Sun Hao's body.

Soon, as if reaching a critical point, the annual rings in Sun Hao's body shook violently, and the running speed suddenly seemed to pause, and then they rushed towards Mu Dan, and Mu Dan no longer stayed quietly in the liver area, but ran along the meridians to the dantian, and turned in the dantian.

With the rotation of Mu Dan, pulling the annual rings Mu Zhenqi kept converging towards Mu Dan, and Mu Dan's size gradually grew up in this rotation, and after half a moment of effort, Mu Dan had grown up a circle. And it looks even more refined.

In the air outside Sun Hao's Cave Mansion, a spiritual energy vortex had been formed, and a large amount of wood spiritual energy swarmed in, dripping down the funnel quickly, and was frantically inhaled by the Mu Dan in Sun Hao's body, like a long whale sucking water.

The momentum of the Spirit Spiral was so great that it even surpassed the scale of the Qi Refiner entering the late stage of Qi refining. Feeling the change of aura in the air, the fire frog in the fire frog swamp roared, and in the depths of the swamp, a huge majestic fire frog lying on the ground suddenly opened its eyes, and everywhere it looked, the swamp grass sneered and burned, and glanced in the direction where Sun Hao was, and the fire frog closed its eyes again.

After Mu Dan increased his circle, he slowly stopped rotating, and then, this Mu Dan ran along the meridians to the liver, as if it was his old nest, and he had just gone to the dantian to play around.

After Mu Dan returned to the liver, the Dan body immediately erupted a steady stream of extremely pure annual ring wood true qi, the surging and vigorous annual ring wood true qi was like a wave in Sun Hao's body layer by layer, one by one the tricks that had not been run before were washed over, and the veins that had not passed through the three layers of qi refining were washed over, Sun Hao only felt that his ears and eyes were clear, his body was light, and his heart was tight, and he had already realized that the three layers of qi refining had broken through.

Sun Hao entered the fourth layer of Qi refining.

Qi refining cultivators, the early stage of qi refining and the middle stage of qi refining are a hurdle, and many monks are stuck in the third layer of qi refining for a lifetime and cannot advance an inch.

Sun Hao, who was still a teenager, had already become a mid-stage Qi refining cultivator.

After the fourth layer of qi refining, you can control things, and the monks in the middle stage of qi refining can realize the flight of imperial objects.

After refining the fourth layer of qi, Sun Hao could try to set up a formation.

Sun Hao didn't expect that he would enter the fourth layer of Qi Refining so quickly, and this cultivation speed once again disrupted his cultivation plan.

The original plan was to try in the Fire Frog Swamp for about a year, and then return to the sect when the Wheel of Fire Duel cultivation was almost over.

It's just been half a year, and this round of fire duel has not yet been practiced, and his cultivation has actually improved.
