Before Master Han returned to the mountain, Lin Hao knew that it was safe to use the bottle in the valley for the time being, because he was the only one in the entire valley, and no outsiders would rashly break into the valley in normal times, which ensured that there would be no accidents during this period, and he could use the bottle boldly and confidently.

Lin Hao estimated the time for Master Han to return to the mountain, and felt that it was impossible for him to find any good medicinal materials in the nearby places, he was afraid that he would have to go to a distant place to find it, and it was likely that he would have to go to those inaccessible places in the deep mountains and old forests, only in such remote places could there be hope to collect some rare medicinal materials, but in this way, it would take at least nearly a year to rush back to the mountains on such a way back and forth, plus the time spent searching for medicinal materials.

Now that nearly half a year has passed since Master Han descended the mountain, it is estimated that he should come back in six or seven months. In the days before he came back, Lin Hao could only give birth to as many herbs as possible that were useful to him, and he had to plan to obtain medicinal materials according to a few rare recipes he knew, and he couldn't blindly waste these green liquors.

The drugs that Lin Hao is about to make that will help increase his strength and break through the bottleneck are all the best holy medicines that Master Han wanted to prepare before, but he couldn't get together the required medicinal materials.

Even Master Han's medical skills are so skillful, and he has never seen any of these medicines, let alone made them himself. You must know that although Master Han has mastered the preparation methods of these holy medicines, he can only look up to the sky and sigh without the medicinal materials in his hands.

When Lin Hao was studying medicine from Dr. Mo before, he was very interested in these rare formulas, although he never expected that he would be able to prepare these extremely precious medicines, but he also memorized a lot of these formulas.

Now these formulas have become Lin Hao's heart, he honestly according to the medicinal materials of various years required above to give birth to herbs, not daring to relax a little, you must know that there is not much time left for him, he must hurry up to prepare these medicines before Master Han returns, and then hide the bottles, and never use them again.

Lin Hao didn't have the slightest confidence that he could use the small bottle in front of Master Han without leaking his feet, he knew very well in his heart how shrewd and careful Master Han was.

Master Han often looked at him with some kind of peculiar gaze, which made Lin Hao always feel that the other party had some secrets that were unfavorable to him, especially in the last year or two, Lin Hao's feeling was even stronger. This Lin Hao and Master Han can't be as close as ordinary masters and apprentices, and they don't have anything to say.

Master Han is actually very good to him in his daily life, neither punching nor kicking, nor scolding, and sparing no effort to help him create all kinds of best conditions in the cultivation of mantras, but there seems to be such a layer of separation between master and apprentice, and there is always an awkward atmosphere floating in his middle.

Master Han was obviously aware of the existence of this rift, but he didn't have the slightest intention of trying to bridge the relationship between master and apprentice, he still did what he had to do, and just blindly supervised Han Li's progress in cultivating the mantra. It's just that when he looked at Han Li, the original gaze that contained a strange expression seemed to gradually decrease, and he hadn't even revealed it for a long time.

But Lin Hao's keen fifth sense vaguely told himself that the other party did not really give up on some of his attempts, but cleverly covered up his own attempts, so that Master Han was a little more vigilant, in this case, how dare he let the other party know the secret of the bottle!

"You can't have the heart to harm others, and you can't have the heart to prevent people"

Whether Master Han really wants to be unfavorable to him, or the fallacy of his own feelings, it is not a bad thing for him to be vigilant against Master Han, if Master Han really has bad intentions for him, he can avoid himself from being hurt by strengthening his precautions, if it is the wrong judgment of his fifth sense, then there is nothing wrong with his increased vigilance, and he himself will not take the initiative to do things to deceive the teacher and destroy the ancestors, he Lin Hao is still a good apprentice of Master Han, and he will do his best to fulfill the filial piety that an apprentice should have.

Lin Hao was still a little uncomfortable thinking of this, he and a strange master and apprentice like Master Han were probably the only ones in the Tianxuanmen, and he couldn't help but sigh.

Lin Hao made all the plans, and also made up his mind to secretly collect the bottle in the future and no longer use it easily, so he was relieved and fell asleep on the bed in a daze.

In the following months, Lin Hao secretly used the green liquor in the bottle to give birth to a large number of precious medicinal materials. He used these medicinal materials to prepare a lot of rare drugs according to the formula, but there were many failures in the preparation process, and each failure made him feel painful. But this can't be blamed on him, these formulas are prepared for the first time, and it is inevitable that they will fail a few times, even if Master Han personally prepares these drugs, there will be one or two misses, and Lin Hao can only comfort himself in this way.

Qingling Pill, Huanglong Pill, Nourishing Myeloid Liquid, Golden Essence Pill, these rare medicines that are rare to see outside are all placed in more than a dozen small bottles, and they are placed in front of Lin Hao one by one, Lin Hao looked at these medicine bottles, his face was also full of joy, with these elixirs, not to mention the fourth layer of the mantra, even the fifth and sixth layers will not take too much effort to practice.

Among these medicines, the Qingling Pill, the marrow nourishing liquid, is the most helpful to his practice, and has the wonderful effect of increasing his strength and being reborn; and the "Qingling Pill" is a rare antidote in the world, which can cure all kinds of poisons in the world; the last "Golden Essence Pill" is a kind of elixir that has a miraculous effect on both internal and external injuries, no matter how serious the internal and external injuries are, as long as you take one of these medicines, even if you can't bring the dead back to life, the injuries will heal immediately, and you can also greatly reduce the injuries and save your life.
