Originally, Lin Hao didn't plan to prepare the last two kinds of drugs that had nothing to do with practice, but after thinking about it carefully, he felt that he was half a person in the rivers and lakes no matter what he said, and God knows if he would have a natural disaster one day? Will he be involved in some fights and killings on the rivers and lakes? It is better to prepare some antidote and healing medicine in advance, in case he is poisoned and injured, and hangs up because there is no good medicine, wouldn't it be too wronged!

After thinking about it like this, Lin Hao still prepared a small amount of the latter two medicines, ready to take them with him in case of accidents, after all, all people's lives are only one, and Lin Hao didn't want to die young.

Although this will affect the quantity of the other two elixirs, thus slowing down the cultivation progress of the mantra, it is also a helpless thing, after all, there can not be so many perfect good things in the world, and there are always some trade-offs in being a human being at certain times.

On the day that the pill was prepared, Lin Hao began to eat one "Huanglong Dan" and "Golden Marrow Pill" respectively according to the taking method mentioned in the formula. These two medicines really deserve to be the legendary holy medicines, under the powerful and amazing power of the medicine, without much effort, he broke through the bottleneck that night and practiced the fourth layer of oral duel.

As soon as he arrived at the fourth floor, Lin Hao immediately experienced a completely different feeling from before, his five senses were "boomed" and was raised to an incredible realm, everything in his eyes suddenly became so bright and clear, and some subtle things that he couldn't see suddenly became magnified, and the details were visible in his eyes, even the slender spider silk in the corners of the room could be seen clearly.

The ear's sense of hearing suddenly became extremely sensitive, and countless sounds that had been heard or unheard before all poured into the ears, such as the "rustling" sound of an earthworm burrowing into the ground more than a dozen feet away, the "buzzing" sound of an unknown insect flying in front of the house, etc., these sounds seemed to sound in his ears, sounding so real and clear;

Lin Hao was surprised and delighted, this was the first time he felt that the time he spent was not wasted in practice since he practiced this mantra, and such a different feeling showed that this mantra was not useless, but had its own uniqueness.

Although the previous layers of cultivation had also improved his five senses to a certain extent, they had not changed so obviously and so dramatically like the fourth layer, which was simply a qualitative improvement, just like a completely different person.

In addition, he also felt that his body was much lighter than before, and his spirit had also made great progress, and now let Lin Hao not sleep for three or five days, it is estimated that there will be no big problem.

Lin Hao savored the things in his body that were completely different from before. If he stayed where he was and didn't move for a while, he could understand the big and small things that were happening within dozens of zhang, and this feeling of being in control of everything made Lin Hao very obsessed. Now he realized that practicing this mantra to the fourth level was really a slight success.

What kind of wonderful feeling will you have after practicing the fifth and sixth layers!

Not long after Lin Hao had just comprehended the mystery of the exercises he was cultivating, Master Han returned to the valley. Not only did he come back on his own, but he also brought back another mysterious figure.

The familiar coughing sound, he was meditating and cultivating in the stone room at that time, striving to be able to improve himself as soon as possible. After noticing Master Han's voice, he quickly regained his luck, walked out of the stone room, and walked in the direction of Taniguchi to meet the master who had not seen him for nearly a year, and as a result, he met Master Han not far from Taniguchi.

Seeing Master Han again, Lin Hao was taken aback, the person was still the same person, but what caught his eye was a gray face without a little anger, although he was also scorched and sick, but he would not be as corrupt as he is now, and he looks like the ultimate has arrived.

What surprised Lin Hao even more was that behind him was a mysterious figure with a cloak on his head, and his whole body was tightly covered by a wide black robe. This person was unusually tall and burly, two heads taller than Lin Hao, but because he was wearing a cloak, Han Li couldn't see this person's face clearly from the outside, and could only vaguely feel that this person's face would definitely be hideous and terrifying.

Lin Hao pressed the question in his heart, hurriedly stepped forward to salute Master Han, and then stood aside respectfully, waiting for Master Han's question.

He knew very well in his heart that the other party didn't care whether his apprentice was polite and respectful to him, but for him as a disciple, the proper master-apprentice etiquette must be done sufficiently, and he couldn't be abandoned at will, giving the other party a feeling of being unruly, which would only put him in a more unfavorable environment.

According to Lin Hao's various understandings of Master Han, and judging from how much he cared about his mantra cultivation on weekdays, he hadn't seen him for such a long time, so it was estimated that as soon as he saw him, he would first ask him about his mantra cultivation status to determine how Han Li's progress was.

Sure enough, Master Han saw Lin Hao take the initiative to greet him from the valley, he was slightly stunned, coughed twice and then asked weakly:

How are you doing?Have you made any progress?" followed by a look of anxiety and anticipation. Lin Hao had already prepared his mind in advance.

It's the same as before, nothing has changed much. Lin Hao didn't intend to tell the other party the truth about his cultivation, because he couldn't explain his current progress like divine help, how could he suddenly and miraculously jump from the third layer to the fourth layer without external force.

Reach out your hand. Master Han's expression became gloomy, and his tone suddenly became stiff.

After Lin Hao noticed Master Han's expression, his heart suddenly chuckled, and he felt a little uneasy.

However, he was not afraid that the other party would personally take the pulse to find out the true qi in his body. Because after entering the fourth layer, Lin Hao unexpectedly found that he could manipulate the strength of the strange true qi in his body at will, and he could completely control the strength of the true qi when he was in the third layer, but he could hide it from the sky and the sea, and he didn't have to be afraid of Doctor Mo's personal inspection.
