Returning to the South Intermediate Court, with Yu Changming's additional advice, Sun Hao greatly improved his memory and preliminary understanding of the second-level basic formation. At the same time, according to the plan, collect all kinds of materials and prepare to go out for trials.

About twenty days later, Qing Lao sent the Yin needle of the mother and son. Moreover, bringing Sun Hao a sum of spirit stones amounting to as much as 5,000 yuan was the first time that the sect's new pill was divided. This spirit stone came very timely, which made Sun Hao's shriveled purse bulge again.

A month later, Qing Lao watched in amazement as the Yin Needle of Zimu was hidden in the grass and suddenly killed, and at this time, the ebony magic sword in Sun Hao's hand was flashing with brilliance to bless Sun Hao's Aoki Entanglement Spell.

Damn, it's really possible to use two magic weapons at the same time. Moreover, this yin needle can be invisible in the wood environment, silently, and with the strength of the young and old, it is difficult to find it without paying attention.

The Yin Needle made of gloomy wood for thousands of years, the main needle reaches the Cheng dù of the intermediate magic weapon, a set of Yin needles is close to the high-grade magic weapon, with Sun Hao's double magic weapon envoy, the two magic weapons are bright and dark, I don't know how many people have died in the perineum.

After confirming the disciple's cultivation and combat effectiveness, Qing Lao had no objection to Sun Hao going to the Fire Frog Swamp for trial. The Fire Frog Swamp is a low-level trial area, and the Fire Frog is a low-level spirit beast, with Sun Hao's cultivation, as long as he doesn't run into the Fire Frog King, the danger should not be great.

Sun Hao and Tong Li went to the Fire Frog Swamp again to begin the trial.

A few days after Sun Hao and Tong Li disappeared in the South Intermediate Courtyard, the manager of the South Intermediate Courtyard, Steward Li, a third-layer Qi refining monk who had always been low-key, honest and had a very low sense of storage, knocked on the door of Qu Youyan's courtyard.

Qu Youyan's injuries had already recovered, he was a personal disciple of Elder Dongfang of Dantang, and there was no shortage of healing pills, at this time, his face was gloomy, and he listened carefully to all kinds of information from the Southern Intermediate Court.

Is there a fire frog swamp? Is there still a shop in Xieyuefang City? After Steward Li withdrew, a cold glint flashed in Qu Youyan's eyes.

Standing in place and thinking for a moment, Qu Youyan walked towards the courtyard of his senior brother, and said, "Senior Brother Yu, senior brother has a question about alchemy, so I came to ask for advice......

Inside the Fire Frog Swamp.

Sun Hao took Tong Li to clean up the perimeter of the Fire Frog Swamp, remove some newly born Fire Frogs, and then re-established a temporary cave within the swamp.

In this trial, most of the fire frogs faced reached the late stage of qi refining, and the later stage of the fire frogs had territorial awareness, most of them acted alone, and a few times they would be a male and a female.

Therefore, Sun Hao and Tong Li can be killed alone.

Different from the first trial, this trial, Sun Hao and Tong Li took separate actions, of course, not far from each other, which was convenient to respond.

Tong Li's way of dealing with the fire frog is very simple, top the shield, step forward, and restrict the movement of the fire frog by the ground trapping technique, and then resist the fire frog, and begin to entangle with the fire frog and practice his own ten thousand grinding strength. In the later stage, the attack power of the fire frog has been greatly improved, and Tong Li can't kill a fire frog in a day.

After nearly half a year of Xiao Wan's polishing and the accumulation of Tong Li, Wan Mo Jin has reached the critical point of the third layer of Qi refining, and on the fifth day of entering the Fire Frog Swamp, Tong Li has already entered the fourth layer of Qi refining after a loud drink, becoming a mid-stage Qi refining monk. This cultivation speed once again surpassed the disciples of the Eastern Courtyard in the same period.

This time, Tong Li didn't show off in front of Sun Hao, because Tong Li knew that Sun Hao had already refined the fourth layer of qi, didn't he see that the materials for this trial were all conjured out of thin air, he had never seen horses eating grass and heard that horses were running, and the storage bag could only be used in the fourth layer of qi refining, Tong Li still knew, Tong Li was honest, but not stupid.

Sure enough, after Tong Li's cultivation was promoted to the fourth level of qi refining, and then looking at Sun Hao, he was already a fourth-level qi refining cultivator.

Compared with Tong Li's simple cultivation method, Sun Hao's cultivation is much more crazy, much more exciting, and much faster.

Sun Hao's comprehensive combat power surpasses Tong Li's strength, and a fire frog in the late stage of qi refining, Sun Hao has no difficulty coping with it. A green wood is entangled, a few convex wooden stakes go down, the ebony magic sword flies out, and a few swords go down, you can kill a late-stage fire frog of the seventh layer of qi refining. The ebony magic sword has two effects, one is an amplification spell, and the other is a direct attack, and the low-level magic weapon still has a lot of lethality against the fire frog of the seventh or eighth layer of qi refining.

And often, this fire frog didn't even have a chance to send out a fireball, so it was hacked to death by Sun Hao, and it couldn't touch Sun Hao at all.

Because of the Mu Dan in his body, Sun Hao's true qi recovery speed has increased greatly, as long as he does not use two magic weapons at the same time, and does not use flying grass spells, in the area where the seventh-layer and eighth-layer fire frogs are active, Sun Hao can basically achieve continuous combat.

Kill the fire frog, skin it, refine the effort, and then set up a basic formation in the area where the fire frog is active.

Practicing the formation is an important part of Sun Hao's trial. The area where the fire frog is active is often a place with relatively abundant aura in the nearby area, which is conducive to the formation of the formation, so every time he kills the fire frog, Sun Hao will practice.

This exercise is quite extravagant, requiring spirit stones and a lot of array materials, and in the past few hundred years, there is really no disciple in the Aoki Sect who has practiced so extravagantly.

There are more than 20 basic formations taught by the Aoki Sect, and there are also more than 30 second-level basic formations imparted, and Sun Hao's plan is to lay out all these basic formations.

After really starting to set up the formation, Sun Hao found out how difficult it was.

At the beginning, with just one basic formation, Sun Hao had to spend more than an hour.

In principle, as long as the disciples can arrange the array materials in place according to the formation diagram and place a spirit stone in the eye of the formation, the basic formation will be successfully set up and will start to operate.

The process seems simple, but it is not easy to really lay out, the material will be misplaced a little bit, and the specific distance between several nodes can not have the slightest error, and the shape and angle between the nodes can not have the slightest error.

Especially the angle, it is difficult to grasp, at the beginning, it is often not the angle is large, or the angle is small, the formation is arranged, the spirit stone is placed in the formation eye, the formation fails, and the basic formation refuses to operate.

Sun Hao was tireless in this, and sank into it, until a month later, Sun Hao set up the first basic formation when he killed more than seventy seventh-layer fire frogs refining and advanced ten miles deeper into the depth of the fire frog swamp again, and immediately approached the eighth-layer fire frog area of qi refining.

Sun Hao's first practice was the basic water array, although the fire frog is a fire spirit beast, but the fire frog swamp is actually a water environment, and the first basic formation Sun Hao chose is the basic water array.

The basic water array is laid out, and the effect is weak, which only makes the nearby water spiritual energy more active, and each courtyard of the Aoki Sect has a spirit gathering array, and the effect is thousands of times that of this basic water array.

However, as the number of fire frogs killed by Sun Hao increased and the number of successful basic water arrays increased, Sun Hao found that the situation had changed slightly.

More than a dozen basic water arrays that are not far away seem to have a superimposed effect, and the activity of the water spiritual qi and the concentration of the water spiritual qi in the nearby area seem to have been greatly improved.

After discovering this change, Sun Hao stopped killing the fire frog and stayed in this area, observing carefully and thinking about the reason for this change. Sun Hao found that these dozen or so basic water arrays seemed to have formed a certain connection and achieved some special effects.

After the imperial envoy ebony magic sword took off to observe, compared with his own formation knowledge, Sun Hao found that if the positions and nodes of the twelve basic water arrays in front of him were slightly transformed, the shape of these twelve basic water arrays was exactly the shape of a second-level basic formation "Double Water Array".

Sun Hao had wondered why there was such a big difference between the basic water array and the secondary basic water array. Now, by chance, Sun Hao discovered that the second-level basic water array was not a superposition of two water arrays, but a formation formed by arranging and combining twelve basic water arrays in a special way.

Sun Hao set up a water array on the spot in the place where he killed the fire frog, and by chance, the twelve water arrays formed the prototype of a double water array, which was inadvertently discovered by Sun Hao.

After discovering this secret, Sun Hao was immediately full of energy, and according to the formation diagram, he outlined the connection between the twelve water arrays and laid out the nodes of the two water arrays.

After more than ten days of busy work, the double water array was finally successfully deployed.

If the basic water array only has one percent of the spirit gathering effect of the first-level spirit gathering array, then the effect of the double water array gathering spirit water aura has reached fifty percent of the first-level spirit gathering array spirit water aura, and the effect of this promotion is quite huge.

The unexpected success of the double water array means that Sun Hao has taken a key step forward in the study of the formation.
