Except that he was kicked in the head by a donkey, he wouldn't do it.

But what to do now, now that he has encountered this kind of dead end, how to choose.

At this time, he admired the monk who invented the Ice and Fire Cloak again, and it could be said that this Ice and Fire Cloak, which did not seem very practical, had actually been developed to the limit by him.

No matter how hard you try to get this hot and cold conversion device, you can't make any greater improvements.

How to increase the conversion speed of cold air and hot air in the case of sharing a channel, it is impossible, looking at the complex device above, what an ingenious idea, what is this want to attain, to come up with such a complex device.

By the way, Qin Gang slapped his head fiercely, sharing a channel, it is not right to use the pipes of the cold system and the heating system clearly, and the isolation device in the middle is also dynamic, and this is it.

This is not too difficult for Qin Gang.

I didn't think of the point of being exhausted, thinking that I had reached a dead end and couldn't solve this problem at all, and I suddenly thought of another better solution.

But Qin Gang was not a little complacent, why, because all his achievements were based on the monk who invented the Ice and Fire Cloth, if it weren't for him, with his current creativity, he would definitely not have thought of such a perfect solution.

It's all 'built on the shoulders of giants'.

Qin Gang thought so, if the person who invented the Ice and Fire Cloak knew that he thought so, he would definitely think that when he met a confidant, his painstaking work could shine more brightly on others, and then she would think that it was a blessing.

It can be said that Qin Gang's solution is not difficult to think of at all, but this does not mean that the master who invented this Ice and Fire Cloth is nothing more than that.

I can't even think of such a simple plan, and the actual situation is not so, because there is a very good saying, that is, I don't know the true face of Lushan, but I was born in this deep mountain, and this is such a thing.

The difficulty now is still not small, not compared to before, Qin Gang's confidence has increased by at least a hundred times, and the amount of transformation in this is relatively large, but it is not too complicated.

Qin Gang has an advantage, that is, he is patient, unlike some impetuous monks, if he repeats an action for a long time, he will feel annoyed and tired.

To put it mildly, Qin Gang is not like this.

Now he's all in it again, and he's lucky that all the materials he needs can be found in his storage bag, and the few that can't be found can also be replaced.

To say that he needs to invest a lot of time now is to make hot and cold pipes, first he used better fine iron stone to make a mold, Qin Gang felt that this was still a little difficult, that is, how to design its size.

This problem doesn't seem to be too big, that is, just make a few more types of pipes, it's nothing more than spending more spirit stones, and the time spent is almost negligible.

Putting the refined iron stone into the furnace to practice molten iron, even if the world's most powerful master of cultivation will take time, and he will not be much better than an apprentice.

The key is the design and mastery of the mold, which is the essence of the skill of practicing the weapon.

Now Qin Gang doesn't want to sit here and wait, he can still do other things, that is, he can come up with the materials needed for the pipe, and the heat pipe he wants to make now obviously can't use the material of fine iron.

The problem is then the material, since the mold comes out, what material should be used, first of all, the mold can be directly excluded, why, because this iron pipe is too easy to transfer heat, the heat is lost in the process of transportation, this is not cost-effective.

He now has his own understanding, this designer of the Ice and Fire Cloak is undoubtedly a very creative master of the cultivation weapon, but it seems that this person is very stubborn, if he thinks of an idea, he will continue to insist, even if he finds that he can't improve it, he doesn't want to use other methods.

This kind of persistence is not necessary in Qin Gang's opinion, because he can take a step back, and he can think that the original idea is not very good, and change to another method, but that guy doesn't seem to be able to even think about it.

It's often too easy for him to get into a dead end, but one thing that can be proven is that if his persistence succeeds, it will make the Ice and Fire Cloak perfect.

That is, even a Qi cultivation period cultivator with mediocre strength can create something inside.

Although Qin Gang's design works quickly, it is imperfect and can only be used partially, but it is correct for him.

Although Qin Gang, who is practical, has a deep respect for invention and creation, he is not a person who engages in invention and creation, and now he just wants to let himself have a suitable ice and fire coat for himself, which he is not as great as those inventors.

His thinking is very simple, simple but practical, in the world of cultivating immortals, there was not much cultivation in the past, and his cultivation in his life was only Jiedan, but people called him a great monk, which is an extremely honorable title for monks.

He knew a lot about cultivating immortals, known as 'Cultivating Immortals Bai Xiaosheng', and he even had to find the reason why people could no longer further cultivate in Yuanying, but it was just a little bit worse.

He once said that simple is good!

Yes, simplicity is good, that's what I said, and now that I think about this particular great monk, what he said is still very reasonable.

Qin Gang designed it this way, that is, to let the cold and heat converge to one point to protect his most important parts, which is very important.

The biggest failure of the designer of this ice and fire cloak is that he protects everything he wants, which is unrealistic.

Now the question in front of Qin Gang is, that is, what material to choose, by the way, someone once said that tree sap is a good material.

Just try it with tree sap, because Qin Gang has a mysterious space on his body, his space is huge, so Qin Gang brought a lot of materials, and this material is in its mysterious space.

If it was just to access materials, the mysterious space could be used infinitely, so since Qin Gang discovered this mysterious space, his cultivation speed was more than ten times faster.

He knew that this could not clearly summarize the role of this human object on himself, that is, without it, maybe with his qualifications, he would say that he cultivated diligently, and now if he reached the middle stage of foundation building, it would be very good.

To say that he is now a fake Dan cultivator, when he came to the Valley of Ice and Fire, he realized that if the time was right, he would not be far from a breakthrough.
