A lot has happened in the past week.

First, Su Mu read all the theoretical books needed to break through the Toad Swallowing Air Method.

The reading order that 404 helped him arrange was really the best.

After finishing the previous book, you can continue to read the next book. Not only will you not find it boring or difficult to understand, but you can also read ten lines at a glance, which greatly improves your reading speed and is much more efficient than reading books before.

It cost Su Mu 10 million to break through the Toad Swallowing Air Method!

This is five times the cost of breaking through the first level of knowledge!

Fortunately, during this period, Su Mu made a lot of money from the foundation-building tutoring classes, the krypton store, and the cat rice restaurant, otherwise he would have no money to make a breakthrough.

Technical research has always been very expensive. It is a good deal to spend only 10 million to achieve a breakthrough in the technique.

After the breakthrough, the name of the martial arts technique was changed to Golden Toad Qi Refining Art, and its grade was upgraded to Grade Three, Class A.

The difference between the new method and the previous one lies in the word "refining". The spiritual energy swallowed into the body is refined and absorbed faster and more efficiently.

When practicing the new technique, the belly will not expand and make a "gulp gulp" sound like a toad's croaking sound like in the "Fishing toad and Swallowing Air" technique. Instead, the six sounds of "he, hu, hiss, xu, hi, and chui" will be emitted to attract spiritual energy and nourish the five internal organs and the upper, middle, and lower three burners.

These are not the only books that Su Mu has finished reading in the past few days.

He also watched the complete video of Cheng Yunlong's flying sword modification technology course.

After spending money to upgrade his score to 10 (perfect), Su Mu discovered that this set of knowledge had two main uses:

First, it can modify the flying sword to better meet the needs and be more suitable for the user.

For example, when they were in the Snow Mountain, Xun Ling and the others' flying swords were restricted by the wind and snow, and their power was greatly reduced. With this technology, they can transform the flying swords before entering the Snow Mountain, so that they will not only not be weakened, but also exert a stronger power.

Secondly, after a breakthrough in flying sword technology, one can specify the direction of strengthening and achieve targeted strengthening, rather than relying on luck to brush attributes.

Of course, whether the enhancement points can be exploded still depends on luck.

"So, if I can summarize and figure out a set of transformation techniques for other magic weapons, can I also achieve targeted strengthening?"

After checking the effect of the flying sword transformation technology, Su Mu once thought about whether he should develop a set of transformation techniques for the multifunctional precision hammer and then create a batch of directional strengthening talismans?

But soon, he gave up the idea.

Researching transformation techniques is not an easy task. It requires studying a lot of books, doing a lot of experiments, and spending a lot of time. At this stage, he is unable to do these things.

Of course, the most crucial reason is the random strengthening symbols, which are better for defrauding krypton... ahem, no, it is to make users feel fresh and surprised during the strengthening process, and to strengthen some unique hammers and develop new schools.

If it is targeted reinforcement, there will be no fun in this aspect.

Su Mu works hard to ensure that consumers have a better experience.

Su Mu has almost finished reading several theoretical books on poisonology.

As for the poison formulas, antidotes, and poison-using techniques that Xu Yue taught, I also spent money to upgrade them to 10 points (perfect).

Unfortunately, Xu Yue didn't test him these days. He probably guessed that he had learned almost everything and didn't want to give him a chance to show off.

In addition to the books he learned and the improved knowledge, Su Mu's cultivation has also been further improved!

The power of the drum and the dragon's blood brought him more benefits than before, and they continued to play a role...

In the past few days, Sumu went to the Lingzhu Forest and helped Xiong Da turn the soil and apply fertilizer twice. He also brought back some Lingxi water, mixed it with Jiao saliva to make fertilizer water, and watered the Lingginseng and Jiaguo seedlings.

The two little ones are so happy, and it is obvious that they are growing faster!

With the Lingxi water and Jiao saliva, Ling Shen complained less and practiced more actively. I believe it won't be long before it can complete the foundation building and officially start the path of spiritual practice.

As for the fruit seedlings, they are much stronger than before. If they continue to be cultivated like this, it is not a dream that they will bloom and bear fruit. At the very least, there will be a lot of leaves that can be used to make wine.

During these few days, Su Ye has been staying at home honestly and has not gone anywhere. He is doing preparation and practice with his high school textbooks and exercises.

Of course, she also did not neglect her spiritual practice.

Although she couldn't learn spells, she still liked to practice. She felt that the more spiritual energy she had, the stronger her luck and affinity with nature would become, and the more obvious the effect would be, which greatly motivated her to practice.

In addition to these changes at home, some things also happened at school.

A new batch of rune figures have arrived at the krypton store factory.

Su Mu taught Ouyang the transformation techniques, as well as several rune figures with higher intelligence points. They completed the transformation of the newly arrived rune figures, thus saving him a lot of time.

Finally, Xiao Ye added strengthening runes to these rune figures, which resulted in a batch of top-quality items. He then selected a few of them and integrated them with the fleshy magic tools.

This time, Su Mu did not look for the rune masters he had worked with before to make the rune components of the fleshy magic weapon, but instead gave it to Ouyang.

Our own people are more reliable and can do things faster.

With this batch of rune figures, the production efficiency of the krypton store factory has reached a new level.

The multifunctional fine hammer and strengthening talisman, which were originally sold out, are now online again.

After these days of fermentation, these two treasures have already become famous. Not only do weapon repairers want one, but people from other professions also want to get one and then enhance it to have the attributes they need.

So every day there are people who stay at the Krypton store page and refresh it constantly, waiting for today's goods to be put on the shelves so that they can start grabbing them!

It is said that a buddy gave the multifunctional precision hammer and strengthening talisman he had snatched to his goddess, and as a result, he won the goddess' heart in one fell swoop and successfully got rid of being single.

This story made many singles envious, barking and rushing to grab the goods, fantasizing that one day they could also get rid of being single with a hammer. There was no doubt at all that the guy who existed in the rumor was a fake.

The excitement of the krypton store happens on the Internet.

Meanwhile, inside the Qingcheng Mountain Cultivation University, there was also a lively event taking place, which was the library cleaning task.

After receiving the prizes sponsored by Su Mu, the book spirits immediately changed the task description. Not only did they follow Su Mu's instructions and list in detail the habits, strengths, and weaknesses of the armored fish to help students better complete the task, they also emphasized the task rewards!

Originally, the students were very unhappy with the library cleaning task, but after seeing the task update and the list of redemption items, all their unhappiness and dissatisfaction were forgotten.

Instead, there was a heroic roar: "I'm going to make these bookworms bankrupt."

Soul-mobilizing runes, soul-cultivating pills, incense to calm the mind and focus the spirit…there are even multi-functional precision hammers and strengthening talismans.

These treasures produced by krypton shops are all very much needed by students. Although they are sold in krypton shops, they cost money after all. If you can get them by completing tasks, who doesn't want to save some money?

Especially the last two treasures, the multifunctional precision hammer and the strengthening talisman. Even if you have money nowadays, you may not be able to get them!

For a while, the self-service task collection machine outside the library and the school's APP were all filled with various messages asking for team formation, and it was very lively.

"I have a first-class A-level cultivation, double majors in body training and sword control, and the scores of each subject are all above 90, support inspection. I can handle being a MT, and I have output as a DPS. I need a team with reasonable distribution. I won't do anything else today, just kill the armored fish, and I will vomit!"

"A professional beast tamer is looking for a team. Professional counterparts, familiar with the detailed information of the armored fish, and can provide tactical suggestions to the team to help the team kill the armored fish better and faster!"

"Spiritual plant major, with many years of experience in pest control, looking for a team with more female practitioners."

"Are there any teams that want a soft girl majoring in fairy drama? She can act cute and shout 666, add all kinds of buffs for you, and supports loli voice, mature sister voice, girl voice, Tieguanyin... giving you multiple sensory enjoyments!"

"Recruit those who can attack with high energy and break defense! Don't recruit those who are not strong enough, so as not to hurt the harmony between classmates. Private me, bring your homework book or final exam transcript!"

Although Su Mu did not go to the scene to see it, he knew about the excitement through 404's description and what he saw and heard in the school APP forum.

In addition to practicing and studying, he took the time to write a strategy article and put it on the school app.

There were few guides on armored fish at this time, and Su Mu wrote a very detailed one. Many students immediately followed the methods in his guide to hunt armored fish. It turned out that the efficiency was really high!

As a result, this strategy post was quickly featured and pinned to the top of the forum, and received worship and gratitude from countless students.

Students majoring in Dingshi are also very popular because they are mentioned in the guide.

Especially the students who are proficient in the butcher knife technique and the jieyi knife technique have become very popular and are fought over by various teams, giving the students majoring in Dingshi a chance to shine.

After a week, Su Mu received a large number of live armored fish and their shells.

Although a lot of rewards were given out, it was not a loss at all.

Su Mu did not leave the live armored fish in the yard, but arranged for Mao Sun to send it to the Krypton factory.

He asked Ouyang to build a breeding room for the armored fish in the factory, and have a special rune operator responsible for breeding and raising these armored fish so that they can produce shells continuously.

Once the shell production of the armored fish stabilizes, we can start mass-producing the 'Hard Shell Blade' and 'Silver Shell Armor' that are fused from them.

And that night a week later.

Su Mu, who had just finished his training and was about to rest, received a call from Ouyang from the Krypton Store factory.

Ouyang reported an important matter to him.

Someone broke into the Krypton store factory at night!

Those rats really set their sights on the Kryptonian factory and took action!
