In addition to the method of fishing for toads and swallowing qi, Su Mu also checked the breakthroughs in several other more important knowledge.

For example, the Spirit Luck Rune, the Cultivation Pill and the Concentration Incense......

Although the spirit rune is not helpful for cultivation, it has a very important role in many fields such as rune array and instrument cultivation, and if it can be broken through and applied to its rune array and magic weapon, it will definitely be able to improve in terms of quality and effect.

Su Mu has always wanted to break through the Spirit Rune, and he has tried before, but he has not received a response.

This time, the krypton plug-in finally did not disappoint him again.

As Su Mu silently broke through in his heart, a text appeared in front of his eyes: [Unable to break through, lack of necessary knowledge].

Su Mu immediately got a list of books needed for a breakthrough: "Unconventional Energy Conversion Studies", "Cultivation Physics", "Rune Data Structures", and a very famous book - "A Brief History of Time".

Do you have A Brief History of Time?

I don't have time, and even if I have it, I won't pick it up......

For the other books in this list, Su Mu can understand. Because they are either related to the rune array, or related to the transformation and application of energy.

But what is the situation in "A Brief History of Time"?

Isn't this book an introduction to the knowledge of the universe? Could it be that the spiritual runes, or spiritual powers, still have something to do with the universe?

Su Mu was amazed.

Because of the lack of relevant clues, I couldn't figure out an answer, so I could only write down this question first, and then find an opportunity to ask Principal Wen or the teacher of the Fu Array for advice.

Peiling Pill and Condensing Soul Incense can also make breakthroughs, but it is also necessary to give the liver books related to pills and chemistry such as "Analytical Chemistry", "Chemistry of Elixirs", "Medicinal Botany and Mineralogy" first.

Su Mu recorded the books needed for various knowledge breakthroughs one by one, and gave them a sequence.

The first thing to do with the liver must be books such as "The Nature of Qi" and "Mathematical Methods" that need to be used to break through the method of fishing for toads to swallow qi.

In second place are the books used to break through the Cultivation Pill and the Spirit Luck Rune.

As for the rest, it's all in the back row, and it doesn't matter if it's late.

Looking at the long list of book titles, Su Mu couldn't help but sigh: "It seems that my future life will be very fulfilling." ”

Now he kind of understands why players have the highest grudge against the liver and krypton game.

Took my money and wanted my life......

Can resentment not be high?!

"I'll go to the library tomorrow, and I haven't seen the book spirit for a while, so I miss it. Eh, wouldn't it be easier to get a book spirit to keep at home and borrow books?"

Su Mu was very excited, but he didn't know the book spirit and the school, would he like it?

Just as he was thinking about it, he suddenly heard the toad swallowing the moon furnace open its mouth and let out a cry of 'goo goo goo gourd'.

A cloud of hot water mist was sprayed out by the toad swallowing the moon furnace, and the scene was similar to a pressure cooker deflating.

Su Mu took a few steps back, distancing himself from the Toad Swallowing Moon Furnace.

The temperature of the mist it spewed out was not ordinarily high, and if it was scalded, even if it was a cultivator, it would be injured.

After a few moments, the toad swallowed the moon furnace and spat out a cloud of poisonous sand.

These poisonous sands are the Pure Land of Bliss.

Is it really dirt......

The Pure Land of Bliss is tangible when not in use. But as long as you take the spiritual power, it will turn into a colorless and tasteless cloud of smoke, which makes people unguardable.

Su Mu put the excess Pure Land of Bliss into the dimensional space, leaving only the amount for the experiment, and after activating it with spiritual power, he let it float towards the puppet man for the experiment.

As soon as the puppeteer's eyes opened, a light curtain was projected, which was the data indicators of various parts of the simulated body. At the same time, under the influence of the Pure Land of Bliss, its body began to dance, and its dancing posture was still very embarrassing.

It still had an expression on its face, sluggish and painful.

The real-time data in the light curtain shows that the experimental puppet man is in a state of psychedelia, and its internal organs are corroded and destroyed by toxins. That's why its expression is both sluggish and painful.

"It's kind of interesting. ”

Su Mu tried to increase the dose, and the painful expression on the face of the experimental puppet was even stronger, and the light curtain data showed that the destruction of viscera and organs was also accelerating.

"As with psychedelic poisons, increasing the dose has the effect of enhancing toxicity. ”

After a few moments, the test ended, and Su Mu got a test report.

In this report, not only the approximate toxic effect of the Pure Land of Bliss is given, but also the process by which this poison first causes the poisoned person to fall into hallucinations, and only then begins to destroy the internal organs.

Because of the deep illusion, even if the poisoned person feels pain, he will not be able to get out of the illusion, but will fall deeper and deeper...... Eventually, he was sent to Elysium to see the Buddha.

Su Mu called Amiya over, entered the test data into its brain, and asked it to simulate the situation of fighting enemies above level 3 and using the Pure Land of Bliss through calculations.

Amiya has followed him in battles with the Nine-Tailed Snake and the Fox Demon, and has also seen drums. The relevant strength model has already been built in the database, and the results calculated from this are at least seventy or eighty percent accurate, if not completely accurate:

Below the third level, the Pure Land of Bliss has significant effects. Levels 4 to 5 can also cause damage with only a higher dose.

But for the powerhouses above level six, the effect of the Pure Land of Bliss is almost none.

Even so, it was very strong. If you change it to a spell, you won't be able to achieve this effect.

It is no wonder that Principal Wen wants to study the way of poison, not without reason.

But there is also a weakness in killing monsters with poison, and that is to spend a lot of money!

Take the Pure Land of Bliss as an example, there are several herbs in the materials for refining, all of which are very expensive.

For many cultivators, if they have that money, isn't it fragrant to buy some Pei Ling Dan to eat? Why spend it on poison? Moreover, there is also the risk of refining, if one is not careful, the enemy is not poisonous, but he poisons himself, how embarrassing is it?

But this is not a problem for Su Mu.

Isn't it just krypton? Dude, I can afford krypton!

I'm not interested in money at all, and I can cheat someone else out of it anyway.

I don't produce money, I'm just a porter of nature!

After doing the test and calculation, the time was already more than two o'clock in the morning, Su Ye had already gone back to the house to sleep, the vegetable cat was lying in the cat nest at the door of her house, and was dozing off with her eyes closed, but she was more vigilant, and when she made a slight noise, she immediately opened her eyes and looked around vigilantly.

Su Mu checked the puppeteer for the experiment and made sure that the test just now had not caused damage to it, so he put it into the space bracelet together with the Toad Moon Swallowing Furnace, Toad Medicine Scale and other magic weapons.

After packing up his things, Su Mu returned to his room, originally to rest, but I don't know if it was because he slept for a few days before, or because of a series of fusions and experiments just now, which made him feel so high that he couldn't sleep.

Lying on the bed, after tossing and turning for a while, Su Mu simply got up.

"I can't sleep anyway, so I might as well find something to do. Didn't you just fuse the snake bone knife, red scale armor, and other equipment? Just take the previous equipment back to the furnace and renovate!"

Su Mu, who had made up his mind, first put a mute spell on Su Ye's room, so as not to disturb his sister with his own operation later. Then he walked to the courtyard and took out a furnace and a set of forging equipment from the space bracelet.

Two spirit crystal cards were inserted into the furnace, and the indicator light of the furnace immediately lit up, and the fire rune array in the furnace immediately operated, and the raging flames appeared with the scorching heat.

Su Mu took out his commonly used war knives, kitchen knives, and a multi-functional Seiko hammer that was strengthened into a melee electric hammer by Su Ye, and at the same time took off the bracelet that could be transformed into a riot armor suit and threw it into the furnace.

This furnace is also a magic weapon, after being improved by the krypton gold plug-in, not only the temperature becomes higher, but it can also smelt up to five different materials at the same time, so that they will not affect each other, greatly improving the melting efficiency.

If it weren't for this function, Su Mu wouldn't dare to throw so many things into the furnace at the same time.

What if there is a reaction and the refining is broken?

After throwing his equipment into the furnace, Su Mu walked up to the rookie cat, raised his foot and kicked it: "Don't sleep, give me your equipment, and I'll give you a boost." ”

The rookie cat was originally unhappy to be kicked, but after hearing this, he immediately turned his anger into joy, and quickly took out his war knife, riot armor suit, and bow and arrow.

With a smile on its face, it asked kindly, "Do you need my help?"

Su Mu didn't say anything polite to it, and nodded, "You have a good grasp of the fire, come and help me watch the fire in the furnace." ”

"Huh?" the rookie cat's face froze. It wanted to tell Su Mu, I just said politely, why are you still serious? But for the sake of equipment, it could only endure it, obediently followed Su Mu into the courtyard, squatted next to the furnace, and became a 'fire burning boy'.

Su Mu threw the rookie cat's equipment into the furnace as well. Looking at the winged bird under the eaves and the bamboo shoots next to the courtyard gate, he added a lot of materials to the stove.

"Don't you give your master a boost of equipment?"

The vegetable cat asked while paying attention to the heat.

Su Mu shook his head and replied: "Your master's strength is not enough, after the equipment is strengthened, the grade will be improved, I'm afraid she won't be able to use it." Besides, aren't you protecting her?"

After a while, the materials in the furnace were refined, and Su Mu took them out one by one, added the snake bones, snake scales, snake skin and other materials of the nine-tailed snake, raised the multi-functional Seiko hammer, and began to forge and manufacture, stirring up pieces of sparks.

When the sky was dark, Sumu finished forging.

A piece of brand-new weapons and equipment was placed in the yard, so that the rookie cats and hairy bamboo shoots were a few of them, and they were drooling at the same time.

"This set is yours, snake bone knife and red scale armor, I won't say more. The string of this bow has been replaced with the tendons of the nine-tailed snake, which is much more powerful, but the force required to open the bow has also increased. ”

After distributing new equipment to the rookie, Su Mu waved his hand at the winged bird and the bamboo shoots: "Don't drool, there are yours too, come over quickly." ”

Winged birds and bamboo shoots are overjoyed.

And Lingshen is unhappy again.

Because it's not equipped...... But who made it too weak to fight?
