Of course Zhang Han understands the principle of thermal expansion and cold contraction, but he didn't expect that metaphysical products can also be used.

Zhang Han still felt that it was not very reliable, if it was the prohibition laid down by the monks of the Jindan period, this method might be feasible.

The prohibition in front of him was arranged by the monks of the distraction period, and it was several orders of magnitude worse.

He confirmed with Jinmao Chicken Transmission again: "Is this method too big?" ”

"Not big." Jin Mao Chicken replied.

"This ...... Don't let me try it? The green tendons on Zhang Han's skull burst out.

"You have to cover it up, you pretend to blow it up for a while, and when the heat is almost over, I'll just secretly open a gap."

Zhang Han was speechless, isn't this a waste of time, but if you don't hide it, it will be difficult to explain, I'm afraid it will make people suspicious.

He found an almost suitable position on the prohibition, and beckoned to Mo Huaiyuan and the others: "Let's concentrate on this one point, first freeze it with the cold ice technique, and then I will use the detonating big fireball spirit rune to blow it up, and dozens of times back and forth should be able to open a gap." ”

Some of the people were skeptical, was it so easy to break the ban laid by the monks during the distraction period?

Seeing that everyone still had doubts, Zhang Han shook his head secretly, feeling that it was not easy to fool, so he persuaded him: "Believe me, you will definitely be able to explode, senior brother, you come first, just use the cold ice trick here." ”

Gao Zhenjie didn't think about it so much, and when he heard Zhang Han call him, he showed the ice trick very neatly.

The prohibition is invisible to the naked eye, completely transparent, and the ice trick acts on it, like an ice cube hovering in mid-air.

Seeing this, Zhang Han pinched a large fireball magic talisman with his two fingers, and crossed a true qi into it.

With a flick of his arm, he threw the flaming spirit rune towards the ice, and when it was about to be banned, a large fireball had already formed.

Zhang Han clenched his right hand into a fist and shouted: "Open!" ”

"Peng!" A big fireball exploded!

Ice cubes are made of pure aura, and large fireballs are also made of pure aura.

The two phases collided, except for a stream of water vapor drifting towards the roof of the cave, not even a wisp of black smoke came out.

Although the ban is invisible to the naked eye, in terms of movement, there is a high chance that it will be unharmed.

This...... It doesn't seem to work.

Of course, Zhang Han also knew it, and said with a smile: "Well, it's very good, a small crack has been blown up." ”

Everyone looked at the water vapor that disappeared suspiciously, and then looked at Zhang Han suspiciously.

Gao Zhenjie, who was outspoken, said to Zhang Han: "But I don't think this method is useful." ”

Zhang Han was a little embarrassed, coughed lightly, and threw Mingxue at Gao Zhenjie with a straight face: "Cough, I don't want you to think, I want me to feel." ”

Gao Zhenjie saw that Zhang Han wanted to use the master's name to pressure him again, so he honestly shut up.

"Believe me, I'm sure I'll blow it up."

Everyone Zhang Han seems to be very confident, but it's not easy to say anything, anyway, there is no other way now.

Mo Huaiyuan also felt that what Zhang Han said along the way seemed to be very reliable, if it wasn't for his insistence on digging a tunnel, everyone wouldn't have seen this medicine field.

Thinking that Zhang Han should also be a little sure, so he took the lead again and cast the Ice Trick on the same position.

Seeing that he had finally succeeded in flickering, Zhang Han threw out a large fireball talisman again.

"Kaka."

"Peng!"

"Kaka."

"Peng!"

……

For the rest of the day, everyone spent the time in constant freezing and exploding.

After dozens of cycles, when everyone was a little deflated, the somewhat boring brocade chicken finally had a move.

When Zhang Han had just thrown out a big fireball spirit rune, he secretly crossed a true qi to go up.

Zhang Han was about to detonate the big fireball as usual, but suddenly found that the big fireball was uncontrollable, and directly burned the ban out of a big hole and pierced it.

The edge of the large hole in the forbidden space flickered, and it seemed that a force was preventing it from repairing the hole.

Hey?!

It was a real success!

This method actually really blew a big hole in the prohibition laid out by the distraction monk.

Everyone couldn't help but be overjoyed, looked back at Zhang Han, and suddenly felt that his image seemed to be a lot greater.

At this time, the brocade chicken, which had been following Zhang Han's side, suddenly found a meaty insect and sneakily came to the entrance of the cave.

The little insect looked around with its fleshy body bowed for a moment, and suddenly popped out quickly.

The eyes of the brocade feather chicken flashed with a hint of essence, and suddenly spread its wings, "Whoosh! The sound flew to the forbidden hole, and pecked the small worm into the stomach.

Everyone was still immersed in the surprise of breaking the ban, and they didn't notice anything except Zhang Han.

The brocade chicken shook its wings and fell through the prohibition into the medicine field.

Zhang Han saw that the brocade chicken had passed through the prohibition, and also came to the entrance of the cave, and stretched out his hand to poke into the prohibition.

Seeing that his arm passed through the hole without hindrance, he couldn't help but exhale lightly, and he could finally make a difference.

Then he flicked his feet, and his whole body pierced through the hole, and then flipped over, and stood firmly beside the brocade chicken.

When Mo Huaiyuan and the others saw that he had arrived safely at the medicine field, they also rushed up and hurriedly passed through the hole.

As soon as everyone arrived at the medicine field, a strong medicinal fragrance came to their faces, and they took two more breaths, and there was a feeling of being fluttering like they had drunk too much wine.

"Hold your breath and stop breathing, you can be poisoned if you inhale too much." Jinmao Chicken reminded Zhang Han.

Zhang Han also noticed the abnormality, and after being reminded by the brocade chicken, he hurriedly held his breath, closed the pores of his body, and reminded everyone: "Hold your breath and be careful of poisoning!" ”

"Hmm...... Why, don't say it sooner. As soon as Gao Zhenjie came in, he felt that the medicinal fragrance was very comfortable in his body, so he took two puffs greedily, and his brain had begun to spin at this time.

After Zhang Han's reminder, Gao Zhenjie hurriedly sat down, and luck forced the aura he had just inhaled out of his body.

Zhang Han saw that everyone was fine, and his eyes looked towards the spirit grass scattered in the medicine field.

There are more than a dozen pillars of spiritual grass planted on the eight horizontal fields, which look very loose.

I don't know if some of them have withered, or if they have been planted so scattered on purpose.

Zhang Han didn't know most of the spiritual herbs planted in the medicine field, and he didn't understand the efficacy.

However, Ji Sicai, who has a medicinal herb business at home, can barely identify a few.

Gao Zhenjie grabbed a handful of leaves and pulled out a spiritual grass like a radish plucked.

"Brother Gao, tap it! Don't break the roots and affect the efficacy of the medicine! Ji Sicai suddenly exclaimed.

Ji Sicai was very heartbroken and took the spirit grass that had just been pulled out, looked at it for a moment and said: "This is the Yellow Dragon Root, which already has five branches, which means that it is already five thousand years old. ”

After speaking, Ji Sicai took out a jade medicine cartridge and carefully put Huanglonggen into it.

Only then did Zhang Han know that the spirit grass had to be stored in a special jade medicine box, otherwise the spirit grass leaving the soil would easily volatilize the medicinal properties.
