After getting up early in the morning, Bai Ziyun habitually opened the system game, and as soon as he entered the game interface, a small interface popped up: "Meet the teacher promotion standards, is it upgraded?" Yes/No. ”

Bai Ziyun smiled slightly, finally the karma value and merit value have reached tens of thousands, because Gongsun Chan went out to fight in the desert, the karmic value has increased very fast recently, and the karmic value has reached tens of thousands a few days ago, but the merit value mainly comes from the usual relief of refugees and the treatment of the plague, and the growth is stable, compared to the karma value that can skyrocket by killing people, and it only reached 10,000 today.

Bai Ziyun clicked "yes", and soon, the light curtain flickered, and then a small interface popped up: "Congratulations to the player for upgrading to level three, please keep up the good work!" ”

The game system has been upgraded to level three, in addition to the game store with three more level of items, there is also one more function: merit and karma can be exchanged two-to-one, that is to say, 2 merit points can be converted into 1 karma point, and the same 2 karma points can be converted into 1 merit point.

This function is very useful, but Bai Ziyun generally does not use this function, after all, the merit value and karma value are not easy to come by, and he doesn't want to lose half of it in vain.

Bai Ziyun looked at the third+-level items again, and found that the level of martial arts and immortal dao in the third-level items had been upgraded by one level, for example, he had seen a lot of martial arts in Huang Yi's novels, and the science and technology had almost been upgraded to the level of World War II, and weapons such as tanks, planes, and submarines appeared.

In terms of scientific and technological information, Bai Ziyun doesn't care much about it, and it is difficult to develop technology like tanks and airplanes without decades of scientific and technological accumulation. What makes Bai Ziyun care is those technologies that are easy to do but have a great effect. For example, cheats such as martial arts.

After looking for a while, Bai Ziyun unexpectedly found a lot of spell books, seeing such a wonderful thing, Bai Ziyun couldn't help it, and exchanged a book for introductory spells, only to find out after reading it that this is similar to martial arts, it is also to open the body's meridians and acupoints, and then use the handprint to form a magic circle to spread the true qi, thus forming a spell.

This kind of spell is called the seal spell, which is different from the immortal soul spell, the fairy soul spell is to burn the magic circle on the soul using runes, as long as you use the true qi, you can instantly send out the spell, but the seal spell is very cumbersome, and you need to keep sealing to complete a spell. Moreover, the amount of true qi that the human body's meridians can withstand is limited after all, so the sealing spell cannot be compared with the immortal soul spell in terms of power.

Although there were many shortcomings of the sealing spell, Bai Ziyun was very interested, and after looking for it in the store, he exchanged it for a book called Fire Serpent Technique. It was a very low-level spell, but it cost him three thousand karmic points, and the martial arts he had exchanged before had never been so high, which made him quite heartbroken.

The Fire Snake Technique is about more than 60,000 words, with several drawings and detailed analysis, just like the manufacturing drawings and usage methods of a cannon, it took Bai Ziyun a few days to understand, and then he retreated and practiced this Fire Snake Technique.

This will Bai Ziyun finally figured out how the spell came about, and the ability to issue spells is not to make the aura or elements resonate and produce spells as said in the novel, but the true qi has a special ability: temporary simulation.

Theoretically speaking, the True Qi can be temporarily simulated into any matter in the world using the magic circle, such as more than 100 elements on the periodic table, any atom and molecule, steel, water, sand and gravel, and even trees, flowers, animals, and humans.

What's a little funny is that the Fire Snake Technique is very similar to the so-called Fire Dragon Technique that Zhang Niujiao has made, which is a fire that spouts out, but to do this, it takes a lot of magic circles to cooperate. The first is the fuel area, this circle is the area where fuel is generated, what makes Bai Ziyun speechless is that the fuel simulated by this circle is actually gasoline; The second is the injection zone, this formation mainly creates a 30-50 air pressure, which can inject fuel to tens of meters to hundreds of meters away. The third is the switch and some other auxiliary areas.

By opening the meridians and acupoints in the human body, a full magic circle and a half magic circle are formed, and then this kind of magic circle is formed into a complete magic through sealing, and a huge dangerous fire snake is spewed out. The structure of this spell is somewhat similar to that of the flamethrower's flamethrower that was often seen on the battlefield in later generations. That's why this fiery snake technique is also called fire-breathing.

As a spell, the Fire Snake Technique is naturally mainly to open up the meridians and acupoints to form a magic circle of the Fire Snake Technique, this process is very monotonous and cumbersome, Bai Ziyun spent more than a month, and it took him more than a month to enter April, before the magic circle was made.

Once the circle is made, it's time to experiment with spells.

On this day, after Bai Ziyun announced that he was out of the customs, the housekeeper Fang Yuan ran over and said, "Master, things are not good, the barbarian Xianbei cavalry is attacking Zhuo County!" ”

Bai Ziyun was slightly stunned and asked, "When did it happen?" ”

"Just yesterday, the master clearly stipulated that you should not disturb your retreat and cultivation no matter what, so I didn't dare to disturb you." Fang Yuan said.

Seeing his relaxed expression, Bai Ziyun knew that the city defense was fine, and he sneered: "It's really surprising that the Xianbei people dare to go deep into Youzhou and enter Zhuo County." ”

"Liu Taishou's analysis may be that Gongsun Shaozhu beat Xianbei too badly, and these Xianbei people should come to retaliate."

"Revenge? How many centaurs did they come? ”

"About five thousand."

Bai Ziyun's eyes were cold, and he said: "Zhuo County is guarded by a city, and the barbarians are not good at attacking cities, so there is no way to take us, they will definitely invade the nearby villages." Pass on my order, the Dragon Elephant Army will bring armor to the enemy, and no matter whether it is a disciple of the Immortal Sect or others, as long as you kill a barbarian, you will get ten points and one level of points in the Hidden Scripture Pavilion. ”

"No!"

Fang Yuan's eyes lit up, this Hidden Scripture Pavilion points were very precious in Zhuo County, and as a supervisor, he was only one hundred level points per month.

After Fang Yuan passed Bai Ziyun's order to him, the soldiers and civilians of Zhuo County heard that killing a barbarian could get ten points and first-level points, which immediately caused a sensation in the whole city, and some martial arts people were sharpening their swords, preparing to kill a few Xianbei cavalry outside the city.

Bai Ziyun didn't take the five thousand cavalry in his eyes, the soldiers and civilians of Zhuo County were enough to deal with it, but he had been in this world for almost a year, and he had seen the so-called barbarians, so under the instigation of curiosity, he also took a group of servants to the city wall.

He was going to try his newfound fire-breathing technique on these Xianbei people. (i.e. Fire Serpent)
