Gu Feichen's cultivation increased greatly after refining the bone and purifying the marrow, but his cultivation potential was only a little better than that of ordinary cultivators.

In addition, there is a serious lack of heavenly and earthly treasures in the human world, and it is difficult to refine the elixir used to enhance physical fitness, so Gu Feichen's cultivation problem has not been fundamentally changed because of this opportunity.

Moreover, he is seriously inexperienced in fighting with people, if he goes with Bai Ruoxi to break through this sinister immortal cultivation realm, I am afraid that he will die a miserable death!

Therefore, Gu Feichen's best choice was to stay in Gushan, run the Gu Family Medicine Garden with Bai Ruoxi, and use the magic circle to protect himself.

Anyway, the secret room left by grandpa is enough for the two of them to use it until the Dan period, but whether they can succeed in the Dan marriage depends on the fate of the two.

And fortunately, there are still array flags and array disks in this world, so it is easy to carry a well-arranged formation magic weapon.

Although in this way, it is generally impossible to set up a powerful forbidden law array. But now in Drum Mountain, there are several layers of average-level formations to defend the medicine garden, which is still enough for the time being.

Besides, if it really doesn't work, just arrange a few more sets of formations. The number can also make up for some defensive holes.

Coincidentally, Gu Changsheng also wanted to make some array weapons for sale. Forbidden magic weapons such as the Array Banner Array Plate will refine a lot of them and flow into the Immortal Cultivation Realm every year, so that they can be exchanged for the required spirit stones, materials and other things.

And the Qimen Sect of the Tang Kingdom is the sect that is famous for cultivating immortals in several nearby countries with its formation, Gu Changsheng plans to go to the Fang Market there before returning to Jiuxiao Gate.

"Big brother, I want to refine a set of Eight Desolation and Six Formations, so that the defense of our Gu Family Medicine Garden can be foolproof!"

Gu Feichen shouted abruptly beside him, pulling Gu Changsheng out of his contemplative state.

For this idea, Gu Changsheng shook his head without hesitation and denied it, this is really unrealistic.

This "Eight Desolations and Six Arrays" is so famous, even in the human world, it is almost to the point that no one knows about it, and no one knows about it!

In some ways, every Immortal Cultivation Family and Immortal Cultivation Sect hopes to have such a large array that is both offensive and defensive.

This magical forbidden method that claims to be able to attract the qi of heaven and earth and create the "Eight Desolation Dragons" to protect the heaven and earth, in addition to covering a large area and having the effect of actively killing the enemy, its effect of transfiguring and covering up the mountain gate and confusing and trapping the enemy is a few points stronger than the great array of those big gate sects!

If the Gu Family Medicine Garden could be guarded by such a strange array, wouldn't it be very secure.

However, in addition to having a master who is proficient in the formation, such a powerful formation also needs to spend a lot of manpower and material resources, and the time it takes is at least two or three years, not to mention that there are a large number of strange formation pressure weapons in the formation!

What's more important is that the spiritual veins of Drum Mountain are too weak, and there is no strong leyline spirit fire to borrow from the spirit, so it is impossible to arrange this kind of large array.

This kid is probably looking at the content of the jade slip and feeling that this kind of formation is extremely popular, so he has this whim.

"Fei Chen, this kind of forbidden array that costs a lot of money, under the premise of not having enough resources, it is better not to spend too much effort on research. I suggest you start by making a small formation banner and get something to use! Gu Changsheng smiled lightly and looked at each other with eyes full of appreciation.

Although he felt that this matter was unreliable, he didn't want to hurt Gu Feichen's self-esteem, and some truths would only be slowly understood in practice.

When Gu Feichen heard this, he first frowned, and then said with a little doubt: "Big brother, the power of the small array is small, and the area covered is only a few zhang in radius, I don't think it's of much use!" ”

"This is a mistake, the small formation is properly applied, and the attack and defense can be reversed in an instant, the key is that you have to understand the way of attack and defense through the formation." Gu Changsheng planned to induce it step by step, and pointed out the key points in the application of the formation.

"The formations are all arranged in advance, and it is not easy to invite the enemy in. Coupled with the weak power of small formations, it is easy to be eliminated by the enemy, and its usefulness is really limited. Gu Feichen still insisted on his opinion, but because he was refuting the eldest brother, he was a little unconfident, so he stammered.

"Let's practice and you'll know the secret!" When Gu Changsheng heard this, he was not disappointed.

If the essence of the way of formation could be explained so easily, there would be formation masters all over the place. In the human world, the formation is mostly used for the defense of important places, and when it comes to applying the formation to the fighting method, most people are not interested.

It is more convenient to use spirit runes when fighting the method, and the application of the formation will only appear in the confrontation of high-level cultivators, so low-level cultivators are generally not interested in studying this kind of thing.

Moreover, the array mages in the immortal cultivation realm are even rarer than alchemists and refiners! Because once you decide to study deeply, it is actually equivalent to giving up the possibility of becoming a great road. After all, people's energy is limited, and it is impossible to take care of cultivation and study advanced formations at the same time in a limited time.

For the immortal cultivators and people of the small sect in the human world, as long as they can use this strange array to protect their own vital points, it is enough to quickly use the formation for both offensive and defensive ends, which is something that is unimaginable!

After all, there are a few Immortal Venerables who have tens of thousands of years of free time like Gu Changsheng in his previous life, and have played alchemy, artifacts, and formations to the point of being superb!

The two walked out of the medicine garden all the way, wanting to find a clearing where they could cast spells, and they happened to meet Bai Ruoxi on the way, and Gu Changsheng called her together to experience the way of formation attack and defense.

Out of the medicine garden, he came to a hillside, and Gu Changsheng decided to demonstrate here.

"That's it, I'll hit two. As for the rules, I can't use anything other than the array, you can do whatever you want. ”

As soon as the words fell, Gu Changsheng took out a few array flags, and with a shake of his body, he attacked them.

The young couple was not slow to react, Bai Ruoxi used the Nine-Leaf Green Bamboo Sword Technique, using a few bamboos next to him, to shoot out dozens of green rays.

Gu Feichen took the opportunity to erect an earthen shield and protect it in front of the two of them.

Suddenly, a flag flew like an arrow, straight into the ground seven or eight feet in front of the two of them.

"Block!" Gu Changsheng snorted.

Immediately afterward, a small defensive array appeared in a radius of five feet, blocking out all the green rays that were shooting.

Gu Changsheng did not enter the formation, but circled the edge of the small formation and quickly approached the two.

Immediately afterwards, his sleeves flicked, and a formation flag flew two feet behind the two of them.

"Get out of the fire!" Another snort.

A small trap formation with a radius of three feet trapped the two of them in place, unable to move. Immediately after that, several fireballs the size of walnuts shot out from the wall of the array, crashing into the inside of the trapped array, and exploding a cloud of red flames when they touched something.

What's even more outrageous is that several fireball charms have been built into this small array in advance. A fist-sized fireball flew in the air, frightening the two of them to hide in Tibet, but the trapped formation was as far as the space of three feet, and there was no place to hide.

In the face of a stormy attack, the two of them had no time to destroy the array flag two feet away behind them. There was no way to dodge, so Bai Ruoxi had no choice but to use the Ice Talisman and Gu Feichen's earth shield to barely block the attacks of these fireballs.

However, this trapped formation is one-way inward, and you can throw magic weapons at will to attack outside, Gu Changsheng took advantage of the two of them to defend the fireball, went around behind the two, and smashed the two of them with mud.

"Don't throw it away, it hurts! It hurts! Big brother spares his life! Gu Feichen felt sorry for his wife, and used his body to help Bai Ruoxi block the mud, and suffered a lot of crimes.

Seeing that the other party begged for mercy, Gu Changsheng withdrew from the trapped formation and said to the two: "If you come to attack, I will defend!" ”

"Coming back? Don't do it! Gu Feichen had already seen the power of this small formation, and he was timid.

"Don't talk nonsense! If you don't suffer a little, how can you understand the profound truth. You see that Ruoxi has more fighting spirit after learning the lesson, how can she be like your mother-in-law! "Gu Changsheng has just been playing, where is he willing to stop.

These array flags were samples made in the last few days, and the materials spent were much more complicated than the talisman making, and if it weren't for the few storage bags he had recently harvested and had a lot of good things in them, he would still be reluctant to make these gadgets.

Gu Changsheng turned around and ran away, motioning for the two to chase after him.

Bai Ruoxi smiled, took Gu Feichen's hand, and chased after him together.

The two chased all the way, and when they were about to catch up, a boulder suddenly appeared in front of them, and Gu Changsheng disappeared all of a sudden. The two were stunned for a moment, and then a green light flew out of Bai Ruoxi's hand and shot at the boulder in front of them.

However, as if it had hit the surface of the water, the green light disappeared directly into the stone.

"This is the Phantom Array!" The two immediately realized that they had inadvertently broken into Gu Changsheng's trap.

"Quickly find that array flag, destroy it and you can break this phantom array!" Gu Feichen was very experienced, and immediately reminded.

However, someone suddenly slapped him behind him, and when he turned around, he only saw a white mist.

Immediately afterwards, Bai Ruoxi's shoulder was also patted, and when she came back to her senses in shock, she didn't know where the opponent had gone......

"Okay, okay, let's surrender, senior brother should withdraw this phantom array!" Bai Ruoxi was also convinced.

"Well, if this small formation can be applied flexibly, the effect will be even more powerful than the spirit rune! And what's even more interesting is that they can be used over and over again! Gu Changsheng said proudly.
