The big spider is the best at cleaning up the garbage, especially in all corners of the room, where it can't reach.

On the other hand, Jiang Feng is very leisurely.

When he returned to his residence, Jiang Feng closed the door and directly released the clone, the big head and the big spider. They can now move or practice at home.

Then, Jiang Feng walked into the room, drank a few sips of tea, changed his clothes, and turned around to go to the refining room.

Now Jiang Feng has mastered a lot of skills, soul talismans, magic skills, soul attack skills, alchemy and refining weapons have all reached the prefecture-level realm, and there are various special skills, Eagle Eye, Yuanyang Red Fire, and various magic weapons, Shaoyang Nanliding, Shouyang Wanhua Furnace, Thousand Illusion Labyrinth, as well as Demon Rain and War Spirit Giant Axe Obsidian.

Taken together, these were enough to make Jiang Feng have a higher height, far more powerful than cultivators of the same level.

But there is no end to learning, and many things may not be used now, but when they are really used, they are indispensable. Right now, Jiang Feng began to study the Lei Yuan Stone, he wanted to integrate the Lei Yuan Stone into the soul rune, and upgrade Mu Yingxue's Thunder Egg again.

These two topics are quite difficult, because this is not a simple upgrade, it is basically a new attempt, especially for the integration of soul runes, it can be said that there is only the initial idea, and I don't know where to start.

Fortunately, the soul talisman is something that Jiang Feng himself has comprehended through painstaking research, and he has a deep understanding of the basic principles of the soul talisman. The thunder egg also had a small upgrade on the thunder egg that Mu Yingxue gave him.

This time, he tried to test them successfully before the refining competition was held.

As for the purpose of doing this, Jiang Feng thought that it was better to be prepared. He participated in the refining competition, and it was impossible for him to admit defeat willingly, so it was very likely that he would advance to become the final winner, and once he advanced to participate in the next round of the Yangping City Refining Competition, his name would be known by more people.

The consequences are self-evident, and the Zhao family is likely to target him and find out his identity and background.

And the worst result is to find out that he is the culprit behind the destruction of Zhao Zhenxuan's soul stone.

Of course, these are just speculations, but it is precisely because of these concerns that Jiang Feng feels the pressure, and he needs more things to press the bottom of the box to protect himself.

The development of soul talismans and thunder and lightning eggs is Jiang Feng's consideration of the unpredictability of the future, and he has many skills without pressing himself, and it has never been a good thing to find a breakthrough from soul talisman and thunder eggs.

In particular, Jiang Feng feels that if there is a breakthrough in these two aspects, it will inevitably bring unlimited results.

Coming to the refining room, Jiang Feng weighed it and decided to start with the Thunderbolt Egg first, after all, there had been a small upgrade before, but it was just to improve its function and type.

Jiang Feng actually had several new ideas in his heart, but they all had certain difficulties.

One is to make a lightning egg launch device, which can launch the lightning egg, which is suitable for the longest-distance sneak attack and shooting, and it is a hundred times stronger than ordinary hidden weapons.

In addition, if the launch function of the launcher is strong and can shoot a few miles away, then the radius controlled by the lightning egg will reach several miles, combined with Jiang Feng's eagle eye, he can use the launcher a few miles away to carry out effective attacks in the medium and long range.

There is also a kind of launch device, to be used for close attacks, the short is within a zhang range, the long is a few zhang range, the launch device, you can shoot dozens of hundreds of tiny lightning eggs at the same time, as if a large net cover past, all the space that the opponent may avoid at once, to achieve all-round, no dead angle attack.

Of course, the above form of attack has strict requirements for the shape of the lightning egg, which can be designed as a needle-shaped lightning egg.

Compared to the Thunderbolt Egg fired at medium and long range, the power of the needle-shaped Thunderbolt Egg will be greatly reduced, but it is almost indiscriminate and is likely to cause all-round damage to the target.

Medium- and long-range attacks, on the other hand, require accuracy and explosive power because of their singularity.

In addition to short-range, medium and long-range, Jiang Feng also considered a real long-range attack, but the requirements were even higher, and it was necessary to design a flying machine first, carrying a thunderbolt egg to the designated location to carry out a long-range attack.

This kind of difficulty is in the design of the aircraft, Jiang Feng can not do it in a short time, because the aircraft must not only be able to fly, but also automatically lock the position, of course, if the aircraft is replaced by some kind of spirit beast and bird, this difficulty will be overcome immediately.

The long-range attack of the lightning egg requires the power of the explosion, because this attack will not only target a person or animal, but the target of the attack may be expanded to houses, giant beasts, etc., and the explosion radius at that time should be at least in zhang.

As mentioned above, to sum up, there are three types of lightning eggs that Jiang Feng needs to prepare for development, short-range attack, medium and long-range attack, and long-range attack.

To be precise, the Thunderbolt Egg is only a part of it, in addition to the Thunderbolt Egg, there is also a corresponding launcher.

First of all, Jiang Feng is studying short-range attacks, and there are two key points in this, one is the launcher and the other is the needle-type lightning egg.

If the shape is too large, it is not suitable for operation, and if it is too small, it is impossible to achieve the effect of a network attack.

Jiang Feng was holding a pen in the refining room, facing the clean and smooth paper, not knowing how to start.

When he picked up the pen, he put it down again, grabbed it again, put it down again, and did it again and again, and he was undecided.

I've thought about all kinds of forms, but it's not ideal in the end. As a result, Jiang Feng, who was full of ambition and was ready to make a big splash, completely fell into a downturn at the beginning.

After suffering for an hour, Jiang Feng reluctantly walked out of the refining room. You can't hold it back or anything, it's better to come out and relax.

The big head was exercising his strength in the courtyard, and he had the body of Zhuqian, and he was as strong as an ox, no, the ox was not as strong as him. Not to mention comparing his strength with a cow, he can now grab a cow and easily lift it above his head with one arm.

He is now in a vacant lot in the courtyard, holding thousands of pounds of boulders as equipment, and performing various exercises to strengthen the muscle groups in his body.

Seeing the master come out, the big head hurriedly put down the boulder and trotted to meet it.

"Master, do you have any eyebrows for your research?" asked the big head flatteringly.

Jiang Feng shook his head, "No." I haven't gotten the hang of it yet, so I don't know where to start!"

"Oh, master, some things depend on inspiration, and when you have an idea, you have to think about it, I think the master lacks a little bit of inspiration for the time being. The big head shook his head and said.

"Yes, it does. Jiang Feng listened to it in his heart and felt that what the big head said was right, "In this way, I'll go out for a walk alone and see if I can find inspiration." ”
